Digestion time of dairy products. How much watermelon, melon, cabbage and bananas are digested in the stomach

The time it takes to digest food significant indicator, but usually no one takes it into account. Nutrients are a source of energy. By correctly arranging the components and calculating the time spent on the processing of a particular product, you can, without maintaining strict diets, always be in shape and not feel hungry. It is not necessary to keep an infinite number of numbers in your head, for this a colossal work of nutritionists has been done and a generally accepted table of digestion of food by time has been compiled. You should not layer meals unnecessarily, feelings of hunger, and if the body did not have time to process the product eaten the day before.

When using culinary delights, it is important to consider that the benefits, the time of absorption by the body and the release of nutrients depend on many factors. Freshness, the method of preparation of the additive, compatibility - everything is important and requires special attention.

The main stage of digestion of products is carried out in the stomach and can take from 30 minutes to 6 hours, while the processing period until the time of defecation takes approximately 20 hours.

The speed of digestion is determined by the moment when food enters the intestines, to simplify the task, consumption products must be properly systematized:

Group	Ingredients	Length of time (in hours)
Fast digestible	Juices of vegetables, fruits, vegetables, berries, fruits (bananas, avocados are not included in the list).	0,45
Medium digestion	Eggs, poultry, seafood, dairy products (cottage cheese, hard cheese are not included in the list).	1 – 2
Prolonged digestion	Potatoes, mushrooms, nuts, legumes, cottage cheese, hard cheese, cereals, bread.	2 – 3
Not absorbed	Canned vegetables, stews, pasta coarse varieties, mushrooms, tea, coffee with milk, protein food animal origin.	3 - 4 or excreted without digestion (pork 6 hours)

Considering the digestion time of food, you can significantly improve your health. Ignoring this indicator, a person carries an impressive amount of rotting food, which adversely affects health, causes diseases of the digestive system, and the cardiovascular system. Moreover, improper, unhealthy diet negatively affects life expectancy.

In order for the processing to be complete, it is important to follow simple rules:

By consuming at the same time products that require a different interval for digestion, the body is exposed to excessive load, which makes no sense. Self-eaten boiled potatoes could get into thin department intestines in an hour, when combined with pork, it is doomed to digestion for a long 6 hours.
The best solution for cooking your favorite dishes, this is a combination of products that require the same amount of time to process. This will use up a little more time than with mono-feeding, but this approach is most acceptable when mixing.
Used as a salad dressing vegetable oils, it should be borne in mind that the processing time in the stomach will increase several times (by 2-3). Oil creates a shell on vegetables, which complicates the processing of salad ingredients by gastric juices and enzymes.
It is impossible to drink food immediately after taking it with teas, water, any drinks. After a meal, it is necessary to wait for the time for the transition of products from the stomach to the intestines. If the rule is violated, there is a decrease in saturation gastric juice, digestion deteriorates and the load on digestive system. Water, diluting food, excludes full digestion, because of this, whole fragments of food penetrate the intestines and, as a result, active action putrefactive microorganisms subject undigested food to decomposition and fermentation.
Drinking water in its pure form, without additional inclusions, it immediately enters the intestines without delay.
Any meal does not tolerate fuss. When consuming any product, it is necessary to chew food carefully, slowly. Thanks to this simple action, it is possible to significantly speed up the digestion process, since the stomach will not need to expend energy on grinding ingredients, and enzyme processing also takes place thoroughly in the oral cavity.
By eating food of animal origin, rich in protein it is important to understand that when heated, it is digested for 2-3 hours, then it passes into the thin section to continue the breakdown of valuable components from food components.
It takes less time to digest cold foods, proteins do not have time to digest and fall into small intestine, where they create favorable conditions for the reproduction of bacteria, which later cause discomfort in the digestive apparatus (gas formation, constipation). It is the use of cooled or chilled food that leads to the accumulation excess weight and the acquisition of a diagnosis of obesity.
The best time for food fermentation - lunch. If there is a need to mix incompatible products, then it is better to do this during the day. Breakfast and dinner do not fully use the reserves of the body. In the morning he has not yet woken up, in the evening he is already ready for bed.
Night time is a period of rest. During this period, food is in stomach dead cargo until the moment of awakening. Deposits of products are decomposed and have a negative impact on the body.

The digestion time of food in the human stomach can be controlled. It is important to understand how quickly each product undergoes enzymatic processing.

The most popular and commonly used ingredients are presented in the table.

The conclusion is obvious. The residence time of food in the stomach is ambiguous, the value can change. It can be adjusted and controlled. Maintaining the health of the body is not difficult, it is enough to be attentive to what enters the mouth. Food should be wholesome, healthy and not create discomfort. With the rational use of food, you can avoid feeling hungry between meals.

With carbohydrates, things are more complicated. Two concepts are required here: "digestion", "assimilation". And they form the basis of the diet for a raw food diet, so clarity is important in this matter. It is when a person decides to switch to a raw food diet that the question arises, what is the rate of absorption of products.

Unfortunately, little attention is paid to this issue, despite the fact that it is fundamental in such a nutrition system. Separate intake means not just sequential consumption of food, which is separated in time, but the intake of one class of products after digestion (assimilation) of another. It is worth saying that the time and speed of assimilation of various products can vary significantly.

Let's talk now about digestion and assimilation of food.

For our body, food is vital, it receives from it the substances necessary for life: nutritious and biologically valuable. But in order to get them, you must first digest food, first splitting it into chemical components, and then assimilate it.

The process of digestion takes a long time, it begins with enzymatic and mechanical processing of food in the oral cavity and ends in the last sections of the intestine. Such a journey of food in the body in time looks like in the following way: food is digested in the stomach from 30 minutes to 6 hours, continues to travel further to the stomach until 7-8 hours small intestine, continuing to split and assimilate along the way, and only then everything that has not had time to be digested enters the large intestine and there can be up to 20 hours.

Now let's move on to the time of digestion and assimilation of products. This time is also called the speed of digestion (assimilation) of products. But in fact, at this time, food is processed only in the stomach. So.

Vegetables:

Tomatoes, cucumbers, lettuce, peppers, herbs - 30-40 minutes (vegetables that are seasoned with oil - up to 1.5 hours).
zucchini, green bean, cauliflower, broccoli, corn - boiled are digested for 40 minutes, seasoned with oil - 50.
Parsnips, beets, carrots, turnips - will be digested within 50-60 minutes.
Potato, sweet potato, Jerusalem artichoke, chestnuts, pumpkin, yams - in 60 minutes.

Berries and fruits:

Berries, watermelon are digested for 20 minutes.
Melon, grapes, citrus fruits and other juicy fruits - 30 minutes.
Apples, pears, cherries, sweet cherries, peaches, apricots and other fruits are digested for 40 minutes.
Fruit, fruit and vegetable salads - 30 - 50 minutes.

Liquids:

Water is almost instantly absorbed if there is no other food in the stomach. It immediately enters the intestines in this case.
fruit, vegetable juices absorbed within 10-30 minutes.
Broths of various saturation - 20-40 minutes.
Milk - up to 2 hours.

Cereals, cereals, legumes:

Buckwheat, polished rice, millet are digested in 60-80 minutes.
Barley, oatmeal, cornmeal - 1-1.5 hours.
Peas, chickpeas, lentils, beans (red, white, black) - 1.5 hours.
Soy - 2 hours.

Nuts and seeds:

Sunflower, pumpkin, sesame, and melon pear seeds are digested on average in about 120 minutes.
hazelnut, peanut, pecan, almond, Walnut- digested 150 - 180 minutes.

Eggs:

Protein is digested in 30 minutes.
Yolk - in 45 minutes.

Milk products:

Any fermented milk drinks- 60 minutes.
Cheese, cottage cheese and homemade fat-free cheese - 90 minutes.
Milk, fat cottage cheese - 120 minutes.
Hard fatty cheeses such as Swiss and Dutch take 4-5 hours to digest.

Fish and seafood:

petty, not oily fish will take 30 minutes to digest.
Oily - 50-80 minutes.
Protein from seafood is digested in 2-3 hours.

Bird:

Chicken, skinless chicken - 90-120 minutes.
Skinless turkey - just over 2 hours.

Meat:

Beef will be digested - 3-4 hours.
Lamb - 3 hours.
Pork is digested in about 5 hours.

We examined the rate of digestion in the stomach of food, as well as the processes that affect this rate. Now you know what digests faster and what is slower, and you can use this knowledge in the fight against extra pounds.

To lose weight, simply do not eat while there is food in the stomach. So, one class of products should be consumed only after the digestion (assimilation) of another has taken place. To do this, you need to know the time of digestion of products. Eating according to this principle will help not only say goodbye to overweight but also keep healthy gastrointestinal tract. The stomach will gradually decrease in size, and the habit of overeating will forever remain in the past. Find out in the article how long it takes to digest different foods.

You should stop eating 3-4 hours before bedtime. Digestion time also depends on individual features body and the amount of food that was eaten.

How long does it take to digest food - find out on estet-portal.com.

Various properties of the human digestive system directly depend on its age. Even in the mother's womb, the first mechanisms of digestion are launched in a child. This is so unique phenomenon, because the life of a little man has not actually begun yet. Gradually, throughout life, digestive process in the stomach of an adult becomes more and more slow. How exactly does digestion and assimilation of food occur in the human body, how does digestion occur in the stomach, what does it depend on and how long do these processes take in adults and children?

The period of processing and assimilation of food are two different concepts. The time frame for this work depends on various factors. Processing is the period during which food is in the stomach, that is, the period during which proteins and fats are broken down. Processing and assimilation of carbohydrates in the body has significant differences. When food enters the esophagus, digestive enzymes break down the complex components of food, and their absorption takes place through the stomach. So, how much food is digested in the stomach?

The food that got into the stomach stays there from half an hour to 360 minutes. In the stomach, under the action of acids and gastric juice, splitting and partial assimilation takes place. nutrients in the small intestine (after about 360-420 minutes). Anything left undigested passes into colon, in which there may be a long period (perhaps a day), after which it exits naturally. How much the stomach digests food can only be understood when all these internal “movements” have passed, it is impossible to speed them up. Water in its pure form is a single liquid that does not need to stagnate in the stomach. When you use a large amount of it on an empty stomach, it almost immediately goes to the intestines.

In an adult and a child, each food requires digestion in different ways, the hours spent on the work of the intestines also differ.

For example, why do newborn babies eat only breast milk, artificial dry substitute or milk from a large cattle? This is due to the fact that their still unformed stomach is capable of assimilating only milk proteins. It takes 120-180 minutes to break down breast milk, and more than 240 minutes for cow or goat milk. Only after 6-7 years the stomach will be able to finally form and increase in volume. Then the duration of assimilation of food will be longer than at a younger age.

Unlike adults, children at this age will take 2 times less effort for the duration of digestion from the prescribed norm for an adult. By the age of 10-12, the coefficient will be approximately 1.5 of the norm. And boys and girls from 15 and older will need as much time as an adult. In addition, it is necessary to take into account the fact that men have a faster metabolism than women. In people old age(70-80 years old) digestion basically lasts twice as long as in adults.

All the food that we eat can be divided into 4 categories according to the duration spent on its processing and assimilation in the stomach:

carbohydrate (the fastest food);
protein (medium);
oily (long);
food digestible with difficulty (too long).

Let's move on to a more detailed description of the categories:

What kind of food is better to eat in order to speed up the function of the stomach for a fast and high-quality metabolism? In order not to harm, but, on the contrary, to help the stomach speed up the metabolism, firstly, you need to eat those delicacies that are digested quickly. Secondly: food belonging to category 4 is not recommended to be consumed daily. Replace pork with chicken, as it contains half the fat. If you suffer from diabetes, then eat everything edible from categories 1 and 2, exclude only sweets - cake, cookies, jam, chocolate. Honey is allowed to be eaten, as it is considered a healthy food for bee production. Nutritionists recommend replacing sugar with honey.

in rational and balanced diet there is a condition called glycemic index and accompanying table. GLYCEMIC INDEX (GI) is an indicator that reflects the speed with which this or that edible product is retained in the body and how it is broken down. The GI table contains a list of foods with high, medium and low scores. GI has a significant impact on the ability to lose weight and obesity.

Under conditions of normal nutrition, the passages of food intake are very simple, the passages of assimilation are a little more complicated, since the efficiency of digestion can vary significantly. It is strongly influenced by such factors:

well-being;
performance of each of the organs;
metabolic rate;
hunger or satiety;
cooking food and more.

Let's consider some of them. For example, why, when comparing the processing of food of a hungry and well-fed person, the assimilation moves will be completely different from each other? Because when a person eats normally, in moderation, he a good appetite, then his metabolism will be good and the digestibility of food will be carried out remarkably. If there is no feeling of hunger, food is consumed without measure, there is nothing to do, then digestibility will proceed in a sluggish form, and the energy consumption of the body will double. This will not bring anything good either for well-being or for internal organs.

The assimilation of food is influenced by the culinary processing of food: boiling, stewing, frying, etc. Porridges are quickly digested as they are boiled. Beef falls into the category of heavy grubs, especially when fried. Sauerkraut is a heavy delicacy and it is not easy for the body to digest it, so it is eaten in fasting, thereby replacing high-calorie products.

The number of dishes affects the body. If for lunch you take: borsch 1 portion, for the second - an omelette, a piece of bread, then the food will be absorbed well. Otherwise, if you take: borscht 2 servings, 2 slices of bread; chicken, fried potatoes, scrambled eggs, for sweets - chocolate and coffee, you will only overload the body and good assimilation you do not shine. Very great importance has a measure in the use of food.

Of course, among other things, the course of assimilation is also influenced by gender, age, habits, characteristics of the organism, even nationality. As you can see, many factors fall under the influence of digestion, and all of them depend on something.

Some foodstuffs are digested in the body a little longer. For instance:

Lactic products. Cow and goat milk when it enters the stomach, it remains there for 120 minutes. Pasteurized and boiled is processed in the stomach more than fresh, as it is known that fat does not dissolve. Kefir, fermented baked milk, curdled milk stay in the stomach for up to 60 minutes. Homemade cheese - after 1.5-2 hours; cheese - up to 4-5 hours, slowly because fats do not dissolve.
Fruits, roots. Fresh apricot puree can take 20 minutes to digest; cherries and other berries, apricots, apples, plums - 40 minutes; pumpkin, zucchini, potatoes - up to 45 minutes; different types of vegetables (carrots, beets, turnips) - up to 50 minutes; sauerkraut processed in the body 3-4 hours. This happens due to the fact that the stomach increases the production of hydrochloric acid. It will take 50 minutes to digest an apple, pear and other hard fruits.
Beverages. Water is absorbed almost immediately if you drink it on an empty stomach; fruit juices 10 minutes-20 minutes; meat broth or light soup - 20-30 minutes; beer and low-alcohol drinks - for a long time, up to 4-6 hours.
Meat products, fish products. Beef, lamb linger in human stomach for quite a long time. For example, chicken - maybe for 60 minutes, and poultry - for 1.5-2 hours; beef - for 180-240 hours; pork - up to 4-5 hours. Chicken is the least fat, and pork is the most, so its frequent use can adversely affect the liver. Fish pickles are absorbed by the stomach quickly - an average of 30 to 60 minutes. Fish and fish delicacies are insanely useful in nutrition.
Cereals and pasta. Buckwheat, rice, millet are digested for 4-5 hours; pasta - 180 minutes.
Beans, corn. Beans, lentils, peas, corn and other legumes are digested on average 1.5-2 hours.

Few people think about what is the optimal temperature for food, what better food- cold or hot. Cold dishes that have undergone heat treatment are harmful due to the fact that they are slowly digested. If there are such dishes, then you can accelerate indigestion, increased gas formation, violation of intestinal motility. It is most harmful to consume cold food for breakfast and dinner. Children are especially undesirable to eat cold food. For example, scrambled eggs, boiled potatoes or soup made in the evening will not work for breakfast if they are served cold. It is better to spend a few minutes and warm them up.

Because of the cool dishes, children often develop a sore throat, and soon problems with the tonsils, which in some cases can even fester.

Nutritionists recommend not to abuse fast food, such as: pizza, hot dogs, pancakes in the form of tubes and envelopes, yeast pancakes with mushrooms, donuts, etc. These delicious products are mostly fatty and high-calorie, low in carbohydrates and proteins . They disrupt gastric functions, metabolism in the body, negatively affect the liver.

All food and drinks are best consumed warm, at room temperature, their assimilation will take 120-180 minutes. Mixing hot and cold food should be avoided, such as eating a bowl of hot cabbage soup and then an ice cream cake. Such a sharp temperature drop is harmful to the body. It is necessary to protect the stomach and intestines from negative impacts, then they can work normally, without failures.

Important processes of mechanical and chemical processing of food and its preparation for further digestion in the intestine take place in the stomach. Due to its shape in the form of a bag, the stomach contributes to the accumulation of food masses and their delay for some time. This is necessary for a more complete processing of food. But not all foods are digested and absorbed at the same rate. Depending on the type of food is in the stomach from a few minutes to several hours.

1 Digestion in the stomach in children and adults

The human stomach is able to digest most of the products that enter it. Food processing occurs due to the production of two main components by the gastric glands - pepsin and hydrochloric acid. They come into contact with the food that has entered the stomach and turn it into chyme - a homogeneous mushy mass, which is then evacuated through the pyloric sphincter into the duodenum.

The process lasts from half an hour to several hours, depending on the type of food eaten. This is what happens in adults. In children infancy the stomach is poorly developed, has a small volume and is able to digest only breast or cow's milk. Digestion in the stomach of a newborn child lasts no more than three hours, which explains the need for frequent feeding.

Pancreas: structure, functions and diseases

2 Product types

The quality composition of the products affects the time of digestion of food in the stomach. Based on this, 4 types of dishes can be distinguished:

1. Food processed by gastric juice for more than 3 hours.
2. Dishes that take 2 to 3 hours to digest.
3. Products that are in the stomach from 1.5 to 2 hours.
4. Food that does not require more than an hour to digest.

The first type includes almost all canned food, dumplings, meat, poultry, coffee and tea with milk, as well as pasta made from first grade flour. The second category of dishes includes bread and other pastries, hard cheeses, cereals, legumes, cottage cheese, all kinds of mushrooms, seeds and nuts. The third type includes different types of vegetables, dried fruits, herbs, dairy products (except for hard cheeses and cottage cheese). The fourth group includes vegetable and fruit juices, kefir, berries, fresh fruits (except banana), chicken egg.

Digestion time individual products in the stomach:

Products	Digestion time
Water	Goes directly into the intestines
vegetable broth	Up to 20 minutes
vegetable juice	Up to 20 minutes
Fruit juice	Up to 20 minutes
Fresh vegetables and vegetable salads without dressing	Up to 40 minutes
Berries and fruits containing a lot of water	20 minutes
Pears, apples, peaches	30 minutes
Boiled vegetables	Up to 40 minutes
Corn, zucchini, all types of cabbage	Up to 45 minutes
Most root vegetables (except those containing starch)	50 minutes
Salads from fresh vegetables with added vegetable oil	Up to 1 hour
Egg	45 minutes
A fish	Up to 1 hour
Vegetables containing starch	1.5 to 2 hours
Cereal porridge (buckwheat, millet, rice and others)	Up to 2 hours
Dairy products (milk, kefir, yogurt, fermented baked milk), except for hard cheeses and cottage cheese	up to 2 hours
Legumes	up to 2 hours
poultry meat	2.5 to 3 hours
Various types of seeds	3 hours
nuts	3 hours
Beef and lamb	4 hours
Pork	5.5 to 6 hours

The small intestine: the structure of the organ and possible diseases

3 Digestion of individual foods in the stomach

Despite the fact that many products can be combined into separate groups in terms of processing time, there are also differences within the groups themselves in terms of their residence time in the body.

Liver functions and symptoms of its diseases

4 Water

Drinking water does not carry an energy load, therefore it does not require digestion and a long stay in the stomach. Drinking on an empty stomach, it immediately enters the small intestine.

5 Fresh fruit

The rate of fruit processing in the stomach directly depends on the content of carbohydrates and water in them:

Grapes and citrus fruits are digested in the stomach for about 30 minutes.
A ripe banana will take 50 minutes to process, while a green one will take about an hour.
It also takes about an hour to split the pineapple pulp.
The most difficult fruit to digest is mango, which takes about 2 hours.

6 Dairy products

The rate of digestion of dairy products is affected by their fat content, the method of preparation and storage:

Faster than all products, the stomach will leave kefir (up to 90 minutes).
Curdled milk, yogurt and fermented baked milk will take up to 2 hours
Fat-free cottage cheese will take about 2 hours to digest, and it will take up to 3 hours to break down a more fatty product.

7 Cereals and legumes

Various types of cereals pass through the stomach in 2-3 hours. Legumes, although they are vegetable crops, require quite a lot of time to digest, as they contain a large amount of protein in their composition:

Will break down the fastest oat flakes(up to 90 minutes). But whole grains can take up to 2 hours to process.
For buckwheat, millet, rice groats need about 2 hours.
The stomach will cope with corn in 150 minutes.
Fresh peas are in the stomach for up to 160 minutes.
Boiled peas require about 3.5 hours to digest.
The organ will spend 3 hours on lentils and beans.

8 Bread

The rate of digestion of bread depends on the grain from which it is made, as well as the ingredients added during the cooking process. rye or wheat bread usually stays in the stomach for 2 to 3 hours.

9 Hard cheeses

The digestion time of hard cheeses depends on their fat content. Processing low-fat varieties can take up to 3 hours. Fatty cheese made from whole milk will stay in the stomach for up to 5 hours.

10 Meat and meat products

Digestion of meat depends on many quality characteristics(fat content, freshness, etc.):

Pork tenderloin leaves the stomach after 210 minutes of processing. Fatter parts require much more time.
The body needs to spend about 3 hours on lamb and beef.
The heaviest product is lard, which can take up to a whole day to digest.

11 Poultry

It takes about 90 minutes for the stomach to process chicken breast. More fatty parts will take more than 2 hours. Turkey also takes a little over 2 hours to digest. Duck and goose, due to the fat content of meat, can be in the stomach for about 3 hours.

12 Vegetables

The speed of digestion of vegetables mainly depends on the content of starch and fiber in them. And the more of them - the longer the process of digestion will continue.

13 Fish and seafood

Low-fat fish species (hake, pollock, cod) are processed by the stomach for about half an hour. More fatty varieties(salmon, pink salmon, trout, herring) require up to 80 minutes of processing. It takes 2 to 3 hours to digest shrimp and sea cocktails.

14 Factors affecting the rate of digestion of food in the stomach

The speed of digestion is influenced by many factors related to the state of the digestive system, and to the methods of preparation of products. Even the way food is eaten significantly affects its further processing and movement through the gastrointestinal tract.

It is known that the reduced acidity of gastric juice significantly reduces the rate of digestion of products. This effect can be observed in people with hypoacid gastritis, who are forced to take drugs that increase acidity and speed up digestion.

Chopped foods will be exposed to the action of gastric juice much faster. Therefore, thoroughly chewed or chopped food in a blender will speed up digestion. Consumption a large number liquid during meals leads to dilution of gastric juice, a decrease in acidity and a delay in food masses. The speed of digestion is also affected by the time of consumption of food. Digestion will be faster in the morning and afternoon.

The way food is prepared and served plays an important role in the speed of its processing. Thermally processed food is digested more slowly than raw (boiled vegetables are processed by the stomach more slowly than fresh ones). Usually meals contain products from different categories. Ingredients that take a long time to digest slow down the processing of other ingredients. For example, pork served with vegetables will significantly reduce the digestion rate of the latter.

Digestion of food is quite difficult process, which depends not only on the qualitative composition of the products, but also on the method of their preparation and consumption, as well as on the individual characteristics of the organism.

And some secrets...

If you have ever tried to cure PANCREATITIS, if so, then you have probably encountered the following difficulties:

medical treatment prescribed by doctors simply does not work;
replacement therapy drugs that enter the body from the outside help only for the time of admission;
SIDE EFFECTS WHEN TAKING PILLS;

Now answer the question: Are you satisfied with this? That's right - it's time to end this! Do you agree? Do not waste money on useless treatment and do not waste time? That is why we decided to publish THIS LINK to the blog of one of our readers, where she describes in detail how she cured pancreatitis without pills, because it has been scientifically proven that pills cannot cure it. Here is a proven way...

Balanced nutrition is the most reasonable type of nutrition today. The term "digestion" in medicine means the time that food is in our stomach. This time is enough to digest proteins and fats, since the time of their splitting is equal to the time of digestion in the stomach.

Let's talk now about digestion and assimilation of food.

The process of digestion takes a long time, it begins with enzymatic and mechanical processing of food in the oral cavity and ends in the last sections of the intestine.

If you suffer from an unhealthy habit - overeating, think about it, maybe you start eating while your stomach has not yet coped with the previous dose of food?

Different foods require different “attention” from our digestive system. What happens to food after we have swallowed it? In order for food to benefit a person and give the necessary energy, it must turn into chemical elements, which the body then absorbs.

This process begins in the mouth, when saliva dissolves and teeth grind food. Later, in the stomach, it is attacked by acid and gastric juices. After leaving the stomach, food enters the intestines, where it continues to interact with gastric juice. Then it is absorbed through the capillaries into the blood passing through the liver - thousands of enzymes located there neutralize any poison (such as alcohol, for example), while retaining useful iron, vitamins and glucose.

More specifically, all food can be divided into 4 categories according to the time of its digestion in our stomach:

- the food that passes quickly (this is mainly carbohydrate food)
- average assimilation time (this is mainly protein food)
- food of long assimilation (it includes fatty foods and a combination of fatty with protein)
- food that is too long in assimilation and practically indigestible.

To the first category include: almost all fruits (with the exception of bananas, avocados and the like), vegetable and fruit juices (not mixed), berries, kefir. All of the above products do not stay in our stomach for more than 1 time. For example, fruits pass into the intestines from the stomach after 40–45 minutes. In some situations, it can take 35-40 minutes.

To the second category include: vegetables, herbs, dairy products with the exception of cottage cheese and hard cheese, sprouts, soaked nuts and seeds, all dried fruits. All of them enter our intestines in about 1.5–2 hours.

To the third category belong: cereals and cereals, nuts and seeds that are not previously soaked in water, cottage cheese and hard cheese, all types of mushrooms, legumes (if they are boiled), bakery products flour higher grades. Their residence time in the stomach is 2–3 hours from the moment they are received.

And finally group 4 includes: tea with milk, coffee with milk (more than 9 hours or not digested at all!), pasta (with the exception of those made from whole grain flour or durum wheat flour), all types of canned food. All products from the 4th group are digested very problematic, or practically not digested at all.

What conclusion can we draw now, guided by the information about how much food is digested in the stomach? Everything is very simple:

- If you want your health, it is not necessary to stick to a diet, you just need to eat as many foods as possible that are absorbed in a short period of time. Thus, you protect your digestive system, and the body spends less energy on its processing.
– Avoid or eat at a minimum those foods that belong to category 4.
– If you have problems with your stomach or intestines, eat only food from categories 1 and 2.

Digestion time in the stomach

After dinner, food is digested in the stomach for two to four hours, after which it enters the small intestine, where the digestion process lasts another four to six hours, after which the food passes into the large intestine, where it can stay for about fifteen more hours.

Water
If you drink water on an empty stomach, the water immediately passes into the intestines.

Juices and salads
– Fruit juices, vegetable juices and broths are digested in 15-20 minutes
– Semi-liquid (mashed salad, vegetables or fruits) 20-30 minutes

Fruit
– Watermelon is digested in 20 minutes
– Melons - 30 minutes
– Oranges, grapefruits, grapes - 30 minutes
– Apples, pears, peaches, cherries and other semi-sweet fruits - 40 minutes

Vegetables
– Mixed salads (vegetables and fruits) are digested within 20-30 minutes
– Raw mixed vegetable salads - tomatoes, leaf lettuce (“roman”, Boston, red, leaf, garden), cucumber, celery, green or red pepper, other juicy vegetables are digested within 30-40 minutes

- If vegetable oil is added to the salad, then the time increases to more than an hour– Vegetables boiled in steam or in water, as well as leafy vegetables - spinach, chicory, kale - 40 minutes

- Zucchini, broccoli, cauliflower, green beans, pumpkin, corn on the cob - 45 minutes
– Root vegetables - turnips, carrots, beets, parsnips, turnips, etc. - 50 minutes

Semi-concentrated carbohydrates - starches
– Artichoke, acorns, corn, potatoes, Jerusalem artichoke, yams, chestnuts - 60 minutes
– Starchy foods, like husked rice, buckwheat, millet, cornmeal, oatmeal, quinoa, Abyssinian panicle, barley are digested on average 60-90 minutes

Concentrated carbohydrates - cereals
– Brown rice, millet, buckwheat, corn flakes, oats (the first 3 are best) - 90 minutes

Beans and legumes (Concentrated carbohydrates and protein, starches and proteins)
– Lentils, lima beans, chickpeas, peas, kidney beans and beans - 90 minutes
– Soybeans - 120 minutes

Nuts and seeds
– Sunflower seeds, pumpkin seeds, pepita, sesame - about 2 hours
- Nuts - almonds, filberts, peanuts (raw), cashews, Brazil nuts, walnuts, pecans - 2.5-3 hours

Milk products
– Skimmed milk, low-fat cottage cheese, ricotta, low-fat cottage cheese or cream cheese about 90 minutes
– Whole milk cottage cheese - 120 minutes
– Hard cheese from whole milk - 4-5 hours

animal squirrels
– Egg yolk- 30 minutes
– Egg (full) - 45 minutes
– Fish - cod, scrod, flounder, sole seafood - 30 minutes
– Fish - salmon, trout, herring, oilier fish - 45-60 minutes
– Chicken - 1-2 hours (no skin)
– Turkey - 2 hours (without skin)
– Beef, lamb - 3-4 hours
– Pork - 4-5 hours

Warm food in the stomach is digested for about 2-3 hours and only after that it enters the small intestine, where the stage of splitting nutrients from food continues.

Two to three hours is the optimal time for the digestion of food in the stomach and the breakdown of proteins. This is the norm, since with the ingestion of undigested proteins in the small intestine, the fermentation process begins.

Cold food in the stomach is digested much faster: proteins do not have time to digest normally and go straight to the small intestine, whose function is based on the breakdown and absorption of carbohydrates, since it is in it that the bacteria responsible for this “event” are located.

As a result of being hit undigested food in the stomach (proteins) to the small intestine, proteins, of course, are not normally absorbed. In addition, bacteria living in meat products (proteins) begin to multiply, which leads to various types discomfort in the gastrointestinal tract (bloating, gases, constipation, etc.).

Many people, even those who monitor their diet, do not take into account such a factor as the time of digestion of food in the stomach and what it affects, so in this article we will understand in detail how long food is digested in the human stomach and what affects the speed of digestion.

Drinking water and other liquids during meals. It is not recommended to drink water and drinks during meals, as they dilute the gastric juice and the digestion time of the food increases (or the food is not completely digested).
Many products after heat treatment(boiling, frying, stewing) are absorbed in the human body longer (the time for assimilation of products increases).
Cold food is digested faster.
Food eaten at lunch is digested faster than food eaten in the morning and evening.
The rate of digestion in the stomach and assimilation in the body is strongly influenced by the type and amount of food consumed, since various products nutrition is absorbed at different rates (from several minutes to several hours), while mixing them may increase the digestion time.

Of these factors, which significantly affect how quickly the food eaten and drinks drunk will be digested, we will dwell in more detail on the speed of digestion of all foods separately and consider how many hours various foods are digested (meat, fish, cereals, vegetables, fruits, etc. .) in the human stomach.

At detailed review presented table, we can conclude that the digestion time in the stomach of various categories of products is:

Water and drinks are absorbed within 20 minutes.
Vegetables are digested within 30-60 minutes (with the exception of vegetables containing starch in large quantities).
Fruits and berries are digested within 20-40 minutes.
Legumes are digested within 2 hours (120 minutes).
Cereals and cereals are digested within 2 hours (120 minutes).
Nuts and seeds are digested within 3 hours (180 minutes).
Milk and dairy products are digested within 2 hours (120 minutes).
Fish and seafood are digested within 1 hour (60 minutes).
Poultry meat is digested within 2.5-3 hours.
Cattle meat is digested within 4-6 hours.
Eggs are digested within 40-45 minutes.

On a note: the most quickly digestible foods are berries, fruits (excluding banana and avocado) and vegetables (with the exception of potatoes and Jerusalem artichoke), as well as fruit and vegetable juices. And products such as coffee, tea with milk, hard cheese, canned fish and meat, stew, pate are digested long time or leave the human body without being digested (partially or completely).

More thoroughly chewed food is digested better and faster.
It is more beneficial for the body to eat foods that have the same digestion and assimilation time in order to reduce the load on the stomach.
Foods with a high protein content are best consumed only in a warm form (they are digested longer in the stomach, due to which all proteins useful for the body are broken down). Cold protein products they do not have time to be digested in the stomach and are sent to the intestines, which can lead to unpleasant consequences (gastrointestinal upset, constipation, bloating).
It is better not to drink water and drinks during meals, so as not to dilute the gastric juice. By the way, ordinary drunk water is absorbed quickly (drinking on an empty stomach), while it does not linger in the stomach and immediately goes to the intestines.
Nuts and seeds are better absorbed if they are first soaked overnight in water, and then crushed.
Vegetables are better absorbed and bring more benefits to the body when they are not seasoned with oils (vegetable, olive), which prevent them from breaking down in the stomach (covering them with a “protective” film).

We hope the table in the article helped you find answers to questions such as how much oatmeal porridge on water, sauerkraut, canned corn, fat-free cottage cheese, dumplings, chewing gum, lard, fish, meat, bread, apple, tangerines, bananas, are digested in the stomach, grapes, persimmons and mushrooms.

In conclusion to the article, it can be noted that knowing how much food is digested in the human stomach, you can build your diet so that there is no big load on the stomach, and many healthy foods are absorbed better and they would be more beneficial for the body. Their helpful tips and reviews, on the topic: the time of digestion of products in the human stomach, leave in the comments to the article and share it in in social networks if it was helpful to you.

Sometimes, without being a doctor, it is worth delving into the details of the digestion process, assessing how long food passes through the gastrointestinal tract, and comparing the absorption of foods by duration. Why know how to digest food quickly? The body of the dock in this matter, let him deal with it. Because the unconscious choice of unsuccessful combinations makes the stomach work harder and provokes the occurrence of complications. Let's see why it is important to know the digestion time of food.

The fuel consumed in the form of food is essential for the functioning of the body. Without the necessary nutrients, the development, repair and protection of cells is impossible. Eaten foods go a long way before becoming the bricks needed for the body, however, the energy costs of processing are highly dependent on the food belonging to a certain class.

The answer to the question of how much food is digested in the stomach may surprise you with a range: from half an hour to 6 hours. How long does it take for food to enter the intestines? After 7-8 hours of moving through the small intestine with parallel splitting, the food passes into the large intestine, where it can stay for about 20 hours. To sum up, how much food fuel will be processed to feces as much as possible (we apologize for the terminology “off the table”): around 1.5 days.

It is necessary to separate the concepts of "digestion" and "assimilation". The first determines how long the food is in the stomach, undergoing processing in the form of splitting into simple chemical compounds. The second involves the absorption of the received elements and their use to replenish energy needs, regenerate cellular tissues, and maintain the viability of organs and systems.

The end date of protein processing is significantly different from the indicators of how much carbohydrates and fats are absorbed over the same period. For the first, the splitting process coincides with the moment of digestion, facilitating further absorption, for the second, digestion is already transferred to the intestines ( complex carbohydrates), delaying penetration into the blood.

It is important to understand how much food is in the stomach, to distinguish between the time of digestion of products and the time of assimilation. Doctors are not recommended to mix meals, throwing in a new batch of "fuel" before the old one is completely processed. In our article, digestion will also mean complete assimilation for ease of orientation.

The period indicating how long the food enters the intestines after being processed in the stomach is the rate of digestion. Products sometimes differ in directly opposite characteristics with respect to this parameter.

The table of digestion of food by time will help to systematize indicators and divide food into groups.

Rapid absorption (carbohydrates)	Berries, fruit and vegetable juices, fruits (except banana, avocado), vegetables	No more than 45 minutes. How much fruit is digested - 35-45 minutes
Medium digestion (proteins with little fat)	Eggs, seafood, poultry, dairy products (except cottage cheese and hard cheese)	About 1-2 hours. How much fish is digested - 1 hour
Long-term absorption (complex carbohydrates)	Potatoes, cottage cheese, hard cheese, cereals, mushrooms, legumes, bakery products, nuts	Approximately 2-3 hours. How much porridge is digested - 2 hours
Not digested	Canned fish, stews, pasta (from durum varieties), tea and coffee with milk, animal meat, mushrooms	More than 3-4 hours or simply displayed. How much pork is digested - up to 6 hours

It became clear how much food is digested in the stomach. The table reflects approximate product grouping vectors, presenting the big picture. However, certain ways of processing and mixing ingredients can affect the absorption of food. We single out three stages of complicating the life of the gastrointestinal tract:

The same digestion time, no heat treatment, fats and sugar are not mixed.
The same digestion time, sugar or butter, spices are added.
Different digestion times, different processing and preparation methods, oils or fats are added.

In the third situation, it will be especially difficult for the body to assimilate the incoming fuel due to fats, which create a film that repels gastric juice, and stretching the processing time of the “material”. A feeling of heaviness and lack of appetite will tell you how long the food actually takes to digest. The simple compatibility of the components in terms of processing time and the pacification of fanaticism from fats will improve overall well-being.

A competent analysis of the data, how much food is digested, will allow you to build an infallible nutrition system that is ideally suited to the body. There are a number general rules, following which will greatly facilitate the work of the digestive tract:

1. Try not to mix products of different time parameters so as not to burden the stomach.

2. Strive to create recipes and combinations within the same time group.

3. The addition of oils increases the duration of food digestion by an average of 2-3 hours.

4. Dilution of undigested food with any liquid will reduce the concentration of gastric juice, complicate the processing of "material" and clog the intestines with undigested residues subject to fermentation.

6. Boiled and fried foods lose some of their useful properties and lose their original structure, so the digestion time increases by 1.5 times.

7. Cold food is processed faster and can lead to obesity due to a violation of the absorption process. The feeling of hunger returns faster, the processes of absorption and utilization are disrupted, the intestines undergo decay processes. Especially this rule concerns protein foods, which should be digested for at least 4 hours, and leave the body cold in 30 minutes.

8. Keep in mind that the most favorable time for processing the “material” is lunchtime, so it is fashionable to quench the thirst for mixing incompatible categories without consequences. Breakfast and dinner do not differ in such activity, so try to select foods of the same digestion time and quick assimilation.

9. When asked if food is digested during sleep, the answer will be a call to simple logic. Nighttime is a period of rest and recovery for the whole body, including the gastrointestinal tract. Eating before bed is tantamount to filling the stomach with useless rotten food, since the body will digest and assimilate the fuel fermented during the night only in the morning.

Despite the visual isolation and independence of the gastrointestinal tract, the indicators of how many hours food is digested in the stomach sometimes directly depend on our conscious choice. Make it easier for your body.

The indicator of how many hours food is digested in the stomach directly depends on the nature of the material itself. This topic has already been touched upon by the above table “The time of digestion of foods in the human stomach”, now we will analyze the categories in more detail.

Cereals and legumes

Let's take cereal. Buckwheat - the digestion time will stop at 3 hours.
The digestion time of rice in the stomach is 3 hours.
The digestion time of millet porridge is 3 hours.
How much barley is digested? Also 3 hours.
The digestion time of oatmeal is 3 hours.
How much is oatmeal digested in water (from flakes)? Only 1.5 hours.
Is corn digestible in the human body? Yes, if there is enough weight in the body to secrete the necessary enzymes. The procedure will take 2.3 hours (corn grits).
Let's move on to beans. How long does it take to digest lentils? The answer is 3 hours.
How much peas are digested (dry) - 3.3 hours.
The digestion time of green peas will stop at 2.4 hours.
How much beans are digested in the stomach? At least 3 hours.

Meat

How much pork is digested depends on the part: tenderloin - 3.3 hours, loin - 4.3 hours.
The digestion time of lamb converges at 3.3 hours.
How long does it take to digest chicken breast? About 3.2 hours.
How many hours meat (beef) is digested does not depend on the part. Approximately 3.3 hours.
How many dumplings are digested in the stomach - 3.3 hours.
The digestion time of fat can exceed a day.

Seafood

How long the fish is digested depends on the variety: low-fat (cod) will fit in 30 minutes, fatty (herring, salmon, trout) - 50-80 minutes.
How long do shrimp digest? About 2.3 hours.
Assimilation of sea cocktails will take approximately 3 hours.

Vegetables

How long does a potato take to digest? Young - 2 hours.
How much is digested roast potatoes? Already 3-4 hours. Boiled - only 2-3 hours.
How are raw carrots digested? For 3 hours. The question why carrots are not absorbed without oil is not entirely correct: vitamin A is poorly absorbed, since it is fat-soluble. With oil, carrots take longer to digest, but the benefits are higher.
How much fresh cabbage (white cabbage) is digested - 3 hours.
How long does sauerkraut take to digest in the stomach? About 4 hours.
How much is boiled beets digested? This will take approximately 50 minutes.

Fruit

Consider kiwi. The digestion time will be 20-30 minutes.
How much an orange is digested - 30 minutes.
Let's take a grapefruit. The digestion time is 30 minutes.
How long does it take to digest an apple? The process will take 40 minutes.
How much is a banana digested? Approximately 45-50 minutes.
Wondering how long a pineapple takes to digest? The answer is 40-60 minutes.
How long does a mango take to digest? About 2 hours.

Animal Products

I wonder how much kefir is digested? 1.4 to 2 hours (non-greasy to fatty).
The digestion time of ryazhenka will be 2 hours.
How long does yogurt take to digest? Approximately 2 hours.
For gourmets: how long does ice cream take to digest? The process takes 2.3 hours.
How much is digested boiled egg- 2.2 hours. What about egg white? The same indicators.
How much fried eggs are digested depends on the volume. A dish of two hard-boiled eggs - 2-3 hours.
How long does an omelet take to digest? A little over 2 hours.

flour products

The time of digestion of bread in the stomach depends on the type of flour: from 3.1 hours (wheat) to 3.3 hours (rye).
The question of how much bread is digested is difficult. The product has a lot of fiber (100 grams = 4 loaves rye bread), which takes a long time to digest.
How long does pasta take to digest? Approximately 3.2 hours.

Sweets (honey, nuts, chocolate)

How much marshmallow is digested - 2 hours.
The digestion time of chocolate will be 2 hours.
How much is halva digested? Approximately 3 hours.
Peanuts, like other nuts, are digested on average 3 hours, but the process can be accelerated if the product is crushed and soaked.
Let's take dry fruits. Digestion time varies from 2 hours (raisins, dates) to 3 (prunes, pears).
The digestion time of honey is 1.2 hours.

Liquids

Coffee with milk is not digested, as tannin and milk proteins form an indigestible emulsion.
The digestion time of tea in the stomach will be about an hour.
How long does water stay in the stomach? Together with food - about an hour. The liquid, drunk on an empty stomach, immediately enters the intestines. It is absorbed at one time about 350 ml (concerns water and food).
How long does soup take to digest? Vegetable broth - 20 minutes, meat - depends on the base and ingredients, difficult to determine.

The residence time of food in the human stomach is an extremely variable value, but it can be easily brought under control. Follow simple rules meals, combine ingredients that are appropriate in time to avoid overloading the gastrointestinal tract and causing fermentation, choose right time. It's easy to be healthy.

The digestive system in the human body has different motor properties depending on age. The mechanisms of digestion of the child in the mother's womb are launched, when the time of life has not actually begun its countdown. In the course of history, food in the stomach of an adult begins to be digested more and more slowly.

To maintain health, a person should know the nuances of his metabolism and how the process of digestion occurs. This information becomes especially relevant when studying cooking methods. various dishes. Then the digestion time becomes optimal. At the same time, the stomach feels comfortable, it will not be tormented by toxins from undigested food residues.

Speaking of digestion, they usually mean a full cycle, that is, the period of time from food entering the human body to its complete breakdown into useful substances. A gastroenterologist can say that even for severe meat products digestion time does not exceed five hours. However, in this case we are talking only about the moment of finding food directly in the stomach. Indeed, this is the average time a lump of food stays in it. Then it moves to the small intestine for absorption, after which it reaches the large intestine, where it is excreted. Of course, how long a specified cycle lasts depends largely on physical condition a person, the individual characteristics of his gastrointestinal tract. In addition, food will be digested differently with excellent diets, the size of single servings of food, and the compatibility of products with each other.

In the science of proper nutrition, there are various tables with the division of products into certain categories. The main thing is to listen to your body and know general principles digestion of food. For ease of reference, the following table can be suggested.

Factors affecting absorption

When planning proper nutrition, it is important to know what determines the time spent by food in the stomach. The following factors influence this:

1. Temperature of finished products. The rate of assimilation of cold food is lower than that of hot food. The digestion time of warm food is the most optimal for the stomach.

2. The method of heat treatment, that is, how exactly a person prepares his food. So when cooking or frying food, its original structure, characteristic of the raw state, changes, some of the enzymes are destroyed. As a result of such transformations, the time required for digestion increases several times.

3. How much food is digested in the stomach also depends on the duration of the meal. The most optimal time for digestion is in the middle of the day (lunch). During the morning and evening receptions food to a person for the same process, you need to spend more resources of the body.

4. Mixing food is one of the most important factors for digestion time. It has been established that different products are characterized by an unequal rate of assimilation. For example, hard cheese takes about 7 times longer to digest than an apple. There are types of food that are not digested at all, or it takes a lot of time and body resources to do this. Accordingly, the time of digestion of food in the stomach will depend on what products get together with a person.

Answering the question about the digestion time, most often they talk about the variety of dishes on the menu and their usefulness, while forgetting to mention the importance of the thermal cooking regime. In this case, warm food of medium temperature is most suitable. This is due to the peculiarities of the structure and functioning of the mucous membranes. human body. In case of violation temperature regime epithelial tissue internal organs begin to suffer, negative processes are triggered that can even lead to cancer.

Science knows the fact that cold and icy food can lead the body to obesity. This is due to the disrupted time of digestion of chilled food in the stomach. Instead of the necessary 4-5 hours, she leaves it in half an hour, as a result of which normal digestion becomes impossible. It is much more difficult to get enough, a feeling of hunger covers a person faster. In addition, the indicated reduction in time leads to an increase in the processes of putrefaction in the intestines, and the normal mechanism of assimilation and utilization is disrupted.

How long the stomach will digest food is directly related to its temperature. Drinking after a meal, even a glass of cold water can do much harm. The protein component does not have the ability to correctly break down into amino acids, and bypassing the stomach, it begins to actively rot in the intestines. Thus, food is digested incorrectly, which in turn serves as the basis for inflammatory diseases(for example, colitis, enteritis, dysbacteriosis). As a result, a person falls into a vicious circle when food is digested in a disturbed way.

Hot food is no less dangerous for the proper functioning of the body. In a similar temperature state, the walls of the esophagus are burned and its mucous membrane necrosis occurs. This can lead to swelling of its tissues and impaired swallowing. Further similar situation leads to the formation of ulcers, which, when healed, cause a narrowing of the esophagus. Thus, at incorrect temperatures, food is not only digested incorrectly, but poses a danger to the functioning of the whole organism.

In order for the diet to be as balanced as possible, it is recommended to take into account not only calorie content, but also compatibility. There are three main categories:

1. In the first - easily combined products that are digested the same amount of time. This category includes fruits and vegetables, as well as mixed salads and broths.

1. bitterness in the mouth, putrid smell;

2. frequent disorders of the gastrointestinal tract, alternating constipation with diarrhea;

3. fast fatiguability, general lethargy;

2. Products of the following type can also be mixed, they take approximately the same time to assimilate. However, sugar, spices and oils are added to them. Due to this, the stomach releases a large portion of acid for digestion, which leads to an increase in the time the food bolus stays in it. Eggs, fish, skinless chicken fall into this list.

3. The third category is characterized by different chemical indicators. They will digest large quantity time, as they are subjected to additional processing during preparation. A wider choice is already presented here: nuts, cottage cheese, cereals, potatoes, mushrooms and legumes.

Thus, food is digested both depending on its physical properties, and from the products with which it is taken. The following list of foods will be digested the longest in the body: pasta (mainly from durum wheat), hard cheese, canned fish, stews, pates, tea and coffee with milk.

Basics separate power supply

It is optimal for the body as a whole, and in particular for the stomach, to eat one type of food at a time. Since the time relevant for its digestion is the same, this approach makes it possible to accurately calculate it and maintain the necessary pause, after which you can eat products from another category. When a person eats inconsistently, it not only changes the time the food stays in the stomach, but also clutters the intestines, leading to the accumulation of toxins.

How long should I wait before the next meal? The amount of time required for this process directly depends on the category whose products are used in this moment. How many hours then do not eat at all? According to the principles of separate nutrition - about two. The exception is fruits: the time between taking them can be reduced to half an hour. It is also important to initially eat liquid meals, do not drink during and after meals. Chew thoroughly until soft. The fewer items a person mixes at one time, the better the food will be digested and there will be less chance of earning obesity.

Even without a medical education, often a person is interested in the intricacies of the digestion process in order to find out how long it takes for food to pass through the gastrointestinal tract, and also to compare the absorption of food by duration.

But why do we need to know this if the stomach does everything by itself without our conscious thinking? And in order for a person to avoid a combination of unsuccessful products, which not only make the stomach work harder, but also provoke the development various pathologies digestive organs.

Food is an integral part of the life of not only a person, but also all living beings that inhabit our planet, as it is a fuel for the body, a source of energy for future achievements. Without vital nutrients, the development, protection and regeneration of body cells cannot be carried out. Foods that enter the body go an extremely long way before they become necessary. building element. It should be noted that the energy consumption for processing certain products depend on their belonging to a certain group.

How much food is digested in the human body. The range is quite large and is half an hour to six hours. How long does it take for food to enter the intestines? After 7-8 hours of slow movement through the small intestine with parallel splitting processes, the food gradually passes into the large intestine, where it can stay for about 20 hours. Average duration conversion of food into feces is one and a half days.

It is also worth pointing out that the terms "assimilation" and "digestion" are completely different. The first implies absorption of incoming nutrients and their use as energy needs, serving to maintain the viability of systems and organs, as well as for the regeneration of cellular matter. Second determines how long food stays in the stomach undergoing staged processing in the form of synthesis into simple chemical compounds.

Every person who cares about their health and the health of their loved ones should know how long food is in the digestive organs, delimiting the time of digestion and assimilation of products. Doctors strongly do not recommend starting a new meal at a time when the old "batch" has not yet gone through the process of complete processing.

The time of digestion of food in the human stomach: table

Digestion rate is an indicator that indicates how long food enters the intestines after processing in the stomach. Sometimes products differ dramatically with characteristics relative to the specified parameter. Therefore, it is important to know how much cottage cheese, meat and other products are digested.

The table below will allow not only to find out the time, but also to systematize the obtained indicators for dividing food into groups.

Category	Products	Time
Not to be digested	mushrooms, meat, tea and coffee with milk, durum pasta, stew and canned fish, mushrooms	The duration of digestion of pork is about 6 hours. More than 4 hours or immediately withdrawn
Sustained absorption (complex carbohydrates)	Nuts, baked goods, legumes, mushrooms, cereals, hard cheese, cottage cheese, mushrooms and potatoes	Cottage cheese - about two hours. Other products - about 2-3 hours
Average digestion time (proteins with little fat)	Dairy and sour-milk products (in addition to hard cheese and cottage cheese), poultry meat, seafood, eggs	Fish is digested for no more than one hour. Other products - about 1-2 hours
Rapid absorption (carbohydrates)	Vegetables, fruits (excluding avocado and banana), vegetable and fruit juices, berries	How long does a banana take to digest? About an hour. How much other fruits are digested - no more than 45 minutes

Based on these data, you can have an idea of how long it takes for the stomach to digest the incoming food.

However, it is worth noting that the method of processing and mixing the products plays a special role.

Let's highlight the main points that greatly complicate the life of the organs of the gastrointestinal tract:

the same digestion time, no heat treatment, no added sugar and fats;
the same duration of digestion, spices, butter and sugar are added;
different duration of digestion, different processing and cooking methods, different fats and oils are added.

A competent approach will allow you to systematize the data obtained and build an infallible nutritional algorithm that is ideally suited directly to your body. Let's get acquainted with the existing number of general rules, which will significantly facilitate the work of the gastrointestinal tract:

Optimal time for various products

It is worth noting that the indicator of the number of hours of digestion of food in the stomach depends directly on the nature of the product itself.
