How long does it take to digest oatmeal cookies? How long does it take for foods to be digested in the body?

The time it takes to digest foods in the stomach plays a key role when creating a menu against the background of diseases of the gastrointestinal tract, as well as when switching to a raw food diet. Digestion of food in medicine is the total time a bolus of food spends in the gastric cavity. During digestion, food is broken down into carbohydrates, proteins and fat components.

The digestion of carbohydrates is more complex and involves multiple digestive mechanisms. Given the importance of carbohydrate-containing components to human health, the question of the rate of digestion raises some difficulties.

Mechanism of food digestion

All food consumed by humans is natural source nutrients, vitamins that are so necessary for the health of the body. The complex digestive mechanism clearly separates combined substances into simple ones, distributes all substances to the necessary parts of the human body.

Everything that is not assimilated is removed from feces. This can simply explain the entire process of digestion. Clinicians talk about the following stages of food digestion:

grinding food in the mouth and breaking down carbohydrates with saliva;
food enters the stomach and is treated with hydrochloric acid for about 4 hours (during this time, primary breakdown and antibacterial treatment occurs);
transformation of the food bolus into mush in the duodenum;
absorption of nutrients;
excretion of undigested food from the colon with feces.

Food is pushed through the intestines at different speeds by contraction of smooth muscle - the peristaltic process.

Note! Thus, digestion time is the interval between food entering the stomach and the penetration of the food bolus into the small intestine for the distribution of nutrients.

Factors influencing the speed of food digestion

On the speed and speed of digestion of food in the cavities gastrointestinal tract the following factors influence:

Temperature conditions. Hot foods always take longer to digest than cold ones. So, 1 hour is enough to digest okroshka, and 3-4 hours to digest hot soup or baked potatoes with meat.
Meal time. Digestion of food occurs faster and more actively during lunchtime, so these hours are the main ones for consuming the bulk of food.
Heat treatment. Raw vegetables are digested in the stomach and intestines much faster than steamed or fried foods. The latter are absent special enzymes, which are responsible for processing food components.
Compatibility of food ingredients. Popular dishes that increase the speed of digestion of food in the stomach include salads and complex dishes. For example, a salad with an apple and hard cheese will take about 4 hours to digest, despite the fact that a fresh apple is digested quite quickly.

Problem excess weight, is also due to non-compliance with the rules therapeutic nutrition. You should not eat until the previous food bolus has been digested.

Classification of products by digestibility

Clinicians, gastroenterologists and nutritionists conditionally classify all food products into several main groups. The classification is based on digestion time. The following groups are distinguished:

Carbohydrates and carbohydrate-containing products. The processing time for food components is about 30-50 minutes. This group includes salads, freshly squeezed juices, raw vegetables or fruits.
Protein foods and some types of fats. The processing time for food made from these ingredients varies within 2 hours. This group includes lean meats, fish, all seafood, chicken eggs, milk.
Complex carbohydrates and starchy ingredients. Processing such food requires the digestive mechanism about 4 hours. This group includes nuts and legumes, hard cheeses, full-fat cottage cheese, cereals, and potatoes.
Indigestible or difficult to digest food. The food ingredients included in this group take a long time to digest or are not digested at all. Such products include coffee and coffee drinks, canned food, mushrooms in any form, fresh flour and confectionery products, pasta, especially those made from wholemeal flour.

Table: type of food and digestion time

How long does it take for foods to be digested? Below is a table of the digestion speed of popular food ingredients

Type of food or food group	Digestion time in hours (1 hour = 60 minutes)
Purified or sparkling water	Instant passage through the food tract to the intestines
Freshly squeezed vegetable juice	25-30 min
Fresh squeezed fruit juice	40-45 min
Raw vegetables and vegetable salads with oil, including raw carrots, cucumbers, tomatoes	45 min
Watery fruits, berries	50 min
Oranges, tangerines, grapefruits	30-45 min
Apples, pears	40-60 min
Peaches, cherries, grapes	45 min
White cabbage, zucchini, eggplant	1-2 hours
Porridge, legumes: beans, corn, peas, buckwheat, rice	2 hours
Dairy and fermented milk products	2.5-3 hours
Beef, pork/poultry meat	5 hours/2.5 hours
Nuts and dried fruits, especially prunes, dried apricots	3.5 hours
Vegetable oils	2 hours

If you combine products with small and high speed digestion of food, then the time spent in the organs of the digestive system is calculated based on the longest digestible product.

A nutritionist-gastroenterologist will help determine which product and how much is digested in the gastric cavity. The longest-lasting products are meat products, including sausages, smoked meats, and semi-finished products. Frying foods and stewing them in large amounts of fat and oil increases the digestion time. Even if the products are fresh are digested in 30 minutes, then when frying or fatty heat treatment, the speed increases to several hours.

Taking into account the speed of food digestion is important when peptic ulcer, gastritis with a tendency to perforation of the mucous membranes, with impaired sphincter function, with gastroesophageal reflux. For such pathologies, the diet includes foods that are digested quickly and prevent the food bolus from stagnating in the stomach.

About the digestion of foods in different time days in a popular program about health:

Important processes of mechanical and chemical treatment food and its preparation for further digestion in the intestines. Due to its bag-like shape, the stomach promotes the accumulation of food masses and their retention for some time. This is necessary for more complete processing of food. But not all foods are digested and absorbed at the same speed. Depending on the type of food, food remains in the stomach from several minutes to several hours.

Digestion in the stomach in children and adults

The human stomach is capable of digesting most of the foods that enter it. Food processing occurs due to the production of two main components by the gastric glands - pepsin and of hydrochloric acid. They come into contact with food entering the stomach and transform it into chyme - a homogeneous pasty 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 happens in adults. In children infancy the stomach is poorly developed, has a small volume and is capable of digesting only breast or cow's milk. Digestion in the stomach of a newborn baby lasts no more than three hours, which explains the need for frequent feeding.

Types of products

The time it takes for food to be digested in the stomach is affected by the quality of the food. Based on this, we can distinguish 4 types of dishes:

1. Food exposed to gastric juice for more than 3 hours.
2. Dishes that take 2 to 3 hours to digest.
3. Products that remain in the stomach for 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 types of mushrooms, seeds and nuts. The third type includes different types vegetables, dried fruits, herbs, dairy products (except hard cheeses and cottage cheese). The fourth group includes vegetable and fruit juices, kefir, berries, fresh fruits(except banana), chicken egg.

Digestion time for individual foods in the stomach:

Products	Digestion time
Water	Goes straight to 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 that contain 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 starchy ones)	50 minutes
Salads from fresh vegetables with added vegetable oil	Up to 1 hour
Egg	45 minutes
Fish	Up to 1 hour
Starchy vegetables	From 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 hard cheeses and cottage cheese	up to 2 hours
Legumes	up to 2 hours
Poultry meat	From 2.5 to 3 hours
Different types of seeds	3 hours
Nuts	3 hours
Beef and lamb	4 hours
Pork	5.5 to 6 hours

Digestion of individual foods in the stomach

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

Water

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

Fresh fruits

The rate at which fruits are processed in the stomach directly depends on their carbohydrate and water content:

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

Dairy

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

Kefir will leave the stomach faster than any other product (up to 90 minutes).
Curdled milk, yogurt and fermented baked milk will require up to 2 hours
Low-fat cottage cheese will take about 2 hours to digest, and more than fatty product will take up to 3 hours.

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 number of squirrel:

Most likely to undergo splitting cereals(up to 90 minutes). But for processing whole grain may take up to 2 hours.
For buckwheat, millet, and rice cereals, it takes about 2 hours.
The stomach can handle corn in 150 minutes.
Fresh peas stay 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.

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.

Hard cheeses

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

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. The fattier parts take much longer.
The organ 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.

Poultry meat

It takes the stomach about 90 minutes to process chicken breast. For the fattier parts it 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 the meat, can remain in the stomach for about 3 hours.

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 swallow it? In order for food to benefit a person and provide 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 preserving useful iron, vitamins and glucose.

More specifically, all food can be divided into 4 categories according to the time it is digested in our stomach:

- food that passes quickly (this is mainly carbohydrate food)
– average digestion time (this is mainly protein food)
– food of long digestion (this includes fatty foods and a combination of fatty and protein foods)
– food takes too long to digest and is 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 within 40–45 minutes. In some situations, it can take 35–40 minutes.

To the second category may 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 approximately 1.5–2 hours.

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

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

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

– If you want to be healthy, you don’t have to stick to a diet, you just need to eat as many foods as possible that are digested in a short period of time. Thus, you protect both your digestive system and the body spends less energy for its processing.
– Avoid or eat to a minimum those foods that belong to category 4.
– If you have stomach or intestinal problems, eat only food from categories 1 and 2.

Digestion time in the stomach

After lunch, 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 remain for about another fifteen hours.

Water
If you drink water on 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

Fruits
– Watermelon is digestible 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, lettuce (Romaine, 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, the time increases to more than an hour– Steamed or boiled vegetables, as well as leafy vegetables - spinach, endive, 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, such as cracked rice, buckwheat, millet, corn flour, oatmeal, quinoa, Abyssinian broom, pearl barley, are digested on average in 60-90 minutes

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

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

Nuts and seeds
– Sunflower seeds, pumpkin seeds, pepita, sesame seeds - about 2 hours
– Nuts - almonds, filberts, peanuts (raw), cashews, Brazilian nut, walnut, pecan - 2.5-3 hours

Dairy
– Skim milk, low-fat cottage cheese, ricotta, low-fat cottage cheese or cream cheese about 90 minutes
– Whole milk cottage cheese - 120 minutes
– Hard cheese made from whole milk - 4-5 hours

Animal proteins
– Egg yolk- 30 minutes
– Egg (completely) - 45 minutes
– Fish - cod, scrod, flounder, sole seafood - 30 minutes
– Fish - salmon, trout, herring, more fatty fish- 45-60 minutes
– Chicken - 1-2 hours (without 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 stomach. small intestine, where the stage of breakdown of nutrients from food continues.

Two to three hours is the optimal time for digesting food in the stomach and breaking down proteins. This is the norm, since when undigested proteins enter the small intestine, the fermentation process begins.

Cold food in the stomach is digested much faster: proteins do not have time to be digested normally and are sent straight to the small intestine, the function of which 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 the hit undigested food in the stomach (proteins) into the small intestine, proteins, of course, are not absorbed normally. In addition, bacteria living in meat products (proteins) begin to multiply, which leads to various types discomfort in the gastrointestinal tract (bloating, gas, constipation, etc.).

Many people, even those who monitor their diet, do not take into account such a factor as the time it takes for food to be digested in the stomach and what it affects, so in this article we will look in detail at how long it takes for food to be 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 food increases (or the food is not completely digested).
Many products after heat treatment(cooking, frying, stewing) are absorbed in the human body longer (the time for assimilation of products increases).
Cold food is digested faster over time.
Food eaten at lunch is digested faster than food eaten in the morning and evening.
The speed of digestion in the stomach and absorption in the body is greatly influenced by the type and amount of food consumed, since different foods are absorbed at different speeds (from several minutes to several hours), and when they are mixed, the digestion time can increase.

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

With a detailed review of the table presented, we can conclude that the digestion time in the stomach for 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 large quantities of starch).
Fruits and berries are digested within 20-40 minutes.
Legumes are digested within 2 hours (120 minutes).
Cereals and porridges 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.
Large meat cattle absorbed within 4-6 hours.
Eggs are digested within 40-45 minutes.

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

More thoroughly chewed food is digested better and faster.
It is healthier for the body to eat foods that have the same digestion and absorption time to reduce the load on the stomach.
Products with a high protein content are best consumed only warm (they take longer to digest in the stomach, due to which all proteins beneficial to the body are broken down). Cold protein products 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 is immediately sent 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 being broken down in the stomach (by covering them with a “protective” film).

We hope the table indicated in the article helped you find answers to questions such as how much oatmeal in water is digested in the stomach, sauerkraut, canned corn, low-fat cottage cheese, dumplings, chewing gum, lard, fish, meat, bread, apples, tangerines, bananas, 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 heavy load on the stomach, and many healthy foods are absorbed better and have more benefits for the body. Their useful tips and reviews on the topic: time of digestion of foods in the human stomach, leave them in the comments to the article and share it in in social networks, if it was useful 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 is good at this matter, let it deal with it itself. Because the unconscious choice of unsuccessful combinations makes the stomach harder and provokes complications. Let's see why it is important to know the digestion time of food.

Fuel consumed in the form of food is essential for the functioning of the body. Without the necessary nutrients, cell development, restoration and protection are impossible. Eaten foods go a long way before becoming building blocks needed by the body, but the energy costs for processing strongly depend on the food’s belonging to a certain class.

The answer to the question of how long food is digested in the stomach may surprise you with its range: from half an hour to 6 hours. How long does it take for food to enter the intestines? After 7-8 hours of progress along small intestine with parallel breakdown, food passes into the large intestine, where it can remain for about 20 hours. Let’s summarize how long it will take for food fuel to be processed into feces (we apologize for the terminology “not for the table”): around 1.5 days.

It is worth separating the concepts of “digestion” and “assimilation”. The first determines how long food remains in the stomach, undergoing processing in the form of breakdown into simple chemical compounds. The second involves the absorption of the obtained elements and their use to replenish energy needs, regenerate cellular tissues, and maintain the viability of organs and systems.

The completion date of protein processing differs significantly 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 spreads 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 foods and the time of assimilation. Doctors do not recommend mixing meals, adding a new batch of “fuel” until the old one is completely processed. In our article, digestion will also mean complete assimilation for ease of orientation.

The period indicating how long it takes for food to enter the intestines after processing in the stomach is the rate of digestion. Products sometimes differ in directly opposite characteristics regarding this parameter.

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

Fast absorption (carbohydrates)	Berries, fruit and vegetable juices, fruits (except banana, avocado), vegetables	No more than 45 minutes. How long does it take to digest fruits – 35-45 minutes
Medium digestion (proteins with some fat)	Eggs, seafood, poultry, dairy products (except cottage cheese and hard cheese)	About 1-2 hours. How long does it take for fish to be digested – 1 hour
Long-term absorption (complex carbohydrates)	Potatoes, cottage cheese, hard cheese, cereals, mushrooms, legumes, baked goods, nuts	Approximately 2-3 hours. How long does it take to digest porridge – 2 hours
Not digestible	Canned fish, stewed meats, pasta (from durum varieties), tea and coffee with milk, animal meat, mushrooms	More than 3-4 hours or it simply disappears. How long does pork take to digest – up to 6 hours

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

Same digestion time, no heat treatment, no added fats or sugar.
Same digestion time, added sugar or butter, spices.
Different digestion times different processing and cooking methods, whether 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 the lengthening of the processing time of the “material”. The feeling of heaviness and lack of appetite will tell you how long the food is actually being digested. A simple combination of components according to the processing time and pacification of fanaticism from fats will improve overall well-being.

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

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

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

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

4. Diluting undigested food with any liquid will reduce the concentration. gastric juice, will complicate the processing of the “material” and clog the intestines with undigested residues susceptible to fermentation.

6. Boiled and fried foods lose some 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 disruption of the absorption process. The feeling of hunger returns faster, the processes of absorption and utilization are disrupted, and the intestines undergo rotting processes. Especially this rule concerns protein foods, which must be digested for at least 4 hours, and when cold leaves the body in 30 minutes.

8. Keep in mind that the most favorable time for processing “material” is lunchtime, so the thirst for mixing incompatible categories can be quenched without consequences. Breakfast and dinner are not characterized by such activity, so try to select foods that have the same digestion time and rapid absorption.

9. When asked whether food is digested during sleep, the answer will be a call to simple logic. Night time is a period of rest and recovery for the entire body, including the gastrointestinal tract. Eating too much before going to bed is tantamount to filling your stomach with useless rotten food, since the body will only digest and absorb the fuel fermented overnight 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 to work.

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 in the above table “Digestion time of foods in the human stomach”; now let’s look at the categories in more detail.

Cereals and legumes

Let's take cereals. Buckwheat – digestion time will stop at 3 hours.
The digestion time of rice in the stomach is 3 hours.
Digestion time for millet porridge is 3 hours.
How long does pearl barley take to digest? Also 3 hours.
Digestion time oatmeal is 3 hours.
How long does it take to digest oatmeal 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 legumes. How long does it take to digest lentils? The answer is 3 hours.

Flour products

The time it takes for bread to be digested in the stomach depends on the type of flour: from 3.1 hours (wheat) to 3.3 hours (rye).
The question of how long the bread takes to digest is difficult. The product contains a lot of fiber (100 grams = 4 loaves rye bread), which takes a long time to digest.

The digestion time for chocolate will be 2 hours.
How long does it take to digest halva? Approximately 3 hours.
Peanuts, like other nuts, take an average of 3 hours to digest, but the process can be speeded up if the product is crushed and soaked.
Let's take dried fruits. Digestion time varies from 2 hours (raisins, dates) to 3 (prunes, pear).
The digestion time for honey is 1.2 hours.

Liquids

Coffee with milk is not digestible, since 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. Liquid drunk on an empty stomach immediately enters the intestines. About 350 ml is absorbed at one time (applies to water and food).
How long does it take for soup to digest? Vegetable broth - 20 minutes, meat broth - depends on the base and ingredients, it’s difficult to determine.

The time food spends in the human stomach is an extremely variable value, but it can easily be brought under control. Follow simple rules when eating, combine the ingredients at the right time to avoid overloading the gastrointestinal tract and causing fermentation, choose the 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 yet actually begun to count down. As history progresses, 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 digestion process occurs. This information becomes especially relevant when learning how to prepare various dishes. Then the digestion time becomes optimal. At the same time, the stomach feels comfortable, it will not be tormented by waste from undigested food residues.

When talking about digestion, we usually mean the full cycle, that is, the period of time from food entering the human body until it is completely broken down 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're talking about only about the moment the food is located 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 the process of its elimination occurs. Of course, how long a given cycle lasts depends largely on physical condition person, individual characteristics his gastrointestinal tract. In addition, food will be digested differently with different diets, the size of single portions of food, and the compatibility of foods with each other.

In the science of proper nutrition, there are various tables dividing foods into certain categories. The main thing is to listen to your body and know general principles digestion of food. For ease of remembering, we can offer the following table.

Factors influencing absorption

When planning proper nutrition It is important to know what determines the time food spends in the stomach. The following factors influence this:

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

2. The method of heat treatment, that is, exactly how a person prepares his food. So, when cooking or frying food, its original structure, characteristic of the raw state, changes, and 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 reception To eat food, a person needs to spend more resources of the body on the same process.

4. Mixing food is one of the most important factors for digestion time. It has been established that different products have different rates of absorption. 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 you need to spend a lot of time and resources on it. Accordingly, the time it takes for food to be digested in the stomach will depend on what foods are delivered to a person.

When answering the question about digestion time, they most often talk about the variety of dishes on the menu and their usefulness, while forgetting to mention the importance of the thermal cooking mode. In this case, warm food is most suitable average temperature. 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 begins to suffer, negative processes are launched that can even lead to cancer.

Science knows the fact that cold and icy food can lead the body to obesity. This occurs due to impaired digestion time of chilled food in the stomach. Instead of the required 4-5 hours, it leaves it in half an hour, as a result of which normal digestion becomes impossible. It is much more difficult to get enough; a person is quickly overcome by hunger. In addition, this reduction in time leads to increased decay processes in the intestines, and the normal mechanism of absorption and utilization is disrupted.

How long the stomach takes to digest food is directly related to its temperature. Drinking even a glass of cold water after a meal can cause great harm. The protein component does not have the ability to be correctly broken 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, dysbiosis). As a result, the person ends up in vicious circle when food is not digested properly.

Hot food is no less dangerous for the proper functioning of the organ. In this temperature state, the walls of the esophagus are burned and its mucous membrane becomes necrosis. This can lead to swelling of its tissues and difficulty swallowing. In the future, this situation leads to the formation of ulcers, which, when healing, cause a narrowing of the esophagus. Thus, at incorrect temperatures, food is not just digested incorrectly, but poses a danger to the functioning of the entire body.

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. The first contains easily combined foods that take the same amount of time to digest. This category includes fruits and vegetables, as well as mixed salads and broths.

1. bitterness in the mouth, putrid odor;

2. frequent disorders Gastrointestinal tract, alternating constipation with diarrhea;

3. fatigue, general lethargy;

2. Products the following type They can also be mixed; they require approximately the same amount of time to be absorbed. 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 remains in it. Eggs, fish, and skinless chicken are included in this list.

3. The third category is characterized by different chemical indicators. They will be digested large quantity time, as they undergo additional processing during preparation. There is already a wider selection available here: nuts, cottage cheese, cereals, potatoes, mushrooms and legumes.

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

Separate Power Basics

It is optimal for the body as a whole and in particular for the stomach to eat one type of food per meal. Since the time required 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 foods from another category. When a person eats inconsistently, it not only changes the time food spends in the stomach, but also clutters the intestines and leads to the accumulation of toxins.

How long should you wait before your next meal? The amount of time required for this process directly depends on the category whose products are consumed in this moment. How many hours then do you 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 and not drink during or after meals. Chew thoroughly until the consistency is as soft as possible. The fewer items a person mixes at one time, the better food will be absorbed and there will be less chance of becoming obese.

Editor's Notes
approx. 1: raw animal proteins take longer to digest a short time than that stated above for prepared/heated animal fats.
approx. 2: given time digestion is given for an ideal situation when you eat one food at a time, chew well, your digestive tract works effectively, such as after fasting. This is the digestion time for optimal healthy person with a healthy eating behavior. Much of this data comes from the work of Dr. Gian-Curcio and Dr. Bass.
Digestion time for a normal diet, for people with suboptimal digestion who have little energy, and for dishes mixed with a large number of ingredients (not assembled in the correct order) is much longer.

For proper nutrition, you need to know not only the number of calories in food, but also the time it takes to digest a particular product, so as not to burden your stomach with a meaningless load in the form of some apple eaten between lunch and dinner. Fast-digesting foods give a person quick energy, while slowly digested foods provide a long-lasting feeling of fullness. Everything that is not included in the digestion time described below takes even longer to digest.

Healthy products that deserve more attention.

There are a number of products that we rarely or never buy. Let us at least remember those vegetables and fruits that our mothers and fathers forced us to eat, but we stubbornly refused. It's a pity! They help improve your health without a doctor's prescription. The benefits of such products have been proven by many years of use, and some - literally for centuries.
First on the list -kiwi. This exotic fruit has become a regular guest on our shelves in recent years. One kiwi a day covers daily norm vitamin C, which is known to strengthen immune system, blood vessels, increases the body's resistance to all kinds of infections, helps the body fight stress. In addition, kiwi contains a lot of magnesium, mineral salts potassium and fiber, which helps remove cholesterol from the body and normalizes digestion.
Second in a row useful product - cranberry. This berry is indispensable for colds - it has an antipyretic effect, kills viruses in acute respiratory infections. The use of these healing berries lowers blood pressure in hypertensive patients, strengthens the gums, and enhances the secretory activity of the pancreas.
Raisins are delicious and nutritious product, has many beneficial properties. Raisins have a strengthening effect on nervous system, helps suppress anger, strengthens the heart. Raisins contain substances that stop the growth of bacteria that cause tooth decay and gum disease.
Finishes our list broccoli. This is an excellent supplier of vitamins C, PP, K, U and beta-carotene. There is almost 2.5 times more ascorbic acid (vitamin C) in broccoli than in such recognized suppliers of this vitamin as citrus fruits. In addition, broccoli is a valuable source minerals: in terms of the content of potassium, calcium, phosphorus, sodium, iron, it competes with its closest relative - cauliflower, surpassing it twice in the content of not only mineral salts, but also protein. Broccoli has also gained fame as a famous fighter against cancer - because of selenium, which this product is especially rich in. And finally, for those who care about their figure, it will be useful to know that the calorie content of broccoli is only about 30 kcal per 100 g!

It takes the body some time to obtain beneficial substances from consumed foods. Gastric juice is unable to instantly break down what has entered the organ. How long does it take for food to be digested in the human stomach? The time distribution table reflects all the nuances of the digestive process.

Undigested food is not absorbed by the body, so filling the stomach with various foods leads to rotting of its remains, and waste and toxins accumulate in the body.

Taking into account the medical interpretation of the digestion process, its duration is determined by the period of time during which the food is in the stomach. The processing process begins from the moment food is in the mouth, where it is chewed and simultaneously processed by saliva. Some substances are absorbed into the blood already at initial stage processing. After chewing, food enters the stomach, and its breakdown begins under the action of enzymes. The next stage - the absorption of products - occurs in the small intestine, where they also continue to be broken down. Food remains in this section of the gastrointestinal tract for 7–8 hours. After this, the remains are sent to the colon. In this place, products can linger for 20 hours.

The influence of age and gender on duration

The duration of the food digestion process is affected by:

physiological characteristics of a person - age, gender;
general health, stressful situations;
the functioning of each internal organ;
individual characteristics of a person and his digestive system.

How older child, the larger the volume of his stomach becomes, and the time required to digest food approaches the same values as for an adult.

The organ of a seven-year-old child, compared to an adult, needs 2 times more time to process food. Upon reaching child's body aged 10–12 years, the ratio of the considered values is 1:5. After 15 years, food in the stomach of a person, both a child and an adult, takes the same amount of time to digest.

IN female body this process takes a little longer. With age, the digestive system begins to work more slowly, so it takes longer to digest food.

Minor factors influencing the processing process

The length of time food stays in the stomach is influenced by the following factors:

Heat treatment of products. In the process of cooking, some of the nutrients are lost, and the digestion process increases.
Temperature of the dish. Food eaten hot can stay in the stomach a little longer, while food eaten cold will reach the intestines faster.
The best option is warm food.
Meal time. Foods eaten at noon are digested and eliminated from the body faster compared to morning and evening meals.

Combination of dish ingredients. To avoid unnecessary stress on the organs, food used for cooking should be digested by the organ in approximately the same amount of time. If you follow this rule, the duration of food in the body will not differ much from the time of digestion when separate meals. The presence of a component in lunch with a long period of breakdown leads to retention of the entire dish in the stomach.

Exercise stress - physical activity After a hearty meal, it helps slow down digestive processes.

Snacks during physical activity should contain mainly foods containing carbohydrates. Such food will be digested quickly and will not cause heaviness. If food is digested long time, bloating and heaviness occur.

During the digestion process important factor– the rate of absorption of nutrients, and not the residence of food in the body.

All foods should be chewed thoroughly; manipulation promotes better processing and absorption of food.

Protein foods are healthier to eat warm; in this form they will stay in the stomach longer - 2–3 hours, but that’s all. healthy proteins will have time to break down to the state necessary for their further digestion in the intestines to amino acids. If you do not adhere to this rule, the stomach will not have enough time to digest them, and the products in this form will go to the intestines, where they can linger. Cold foods containing proteins often cause constipation, indigestion and bloating.

Complex carbohydrates in the stomach are almost not digested; the breakdown process is carried out under the influence of saliva swallowed along with food.

Should be avoided simultaneous administration food and water. Under the influence of diluted gastric juice, food takes longer to digest and the quality of digestion decreases. Water facilitates the penetration of food into the small intestine that has not undergone the entire digestion process. Such food is not broken down and absorbed, so it begins to rot. Along with food, bacteria also enter the intestines, so such food is not only not absorbed in the intestines, but also causes indigestion.

Nuts and seeds soaked in water overnight and then crushed are digested better and faster than when eaten whole.

Using oil when preparing vegetable dishes prevents the breakdown of foods in the stomach by covering them with a greasy film. Food stays in the organ for 60–90 minutes, but by better absorption it won't lead to food.

An example of calculating the duration of food digestion

The obtained value is approximate; in addition, it is necessary to take into account the amount of the predominant ingredient in the dish. If the vinaigrette includes vegetables, the dish is digested within 1–1.5 hours, and peas – 3 hours. The arithmetic average is 2 hours. There are more vegetables in the salad, so the nominal digestion time for the dish is 1.5–2 hours.

The indicators given in the table about the duration of food digestion are average values and are valid if the products were consumed separately. U different people these numbers may vary slightly.

Subtleties of eating

Foods must be consumed in the correct sequence, taking into account their digestion time. If you eat fruit immediately after meat dish, discomfort can't be avoided. The main meal will not allow the fruit to pass first into the intestines until it is digested, so the fruit will begin to ferment and cause bloating in the stomach area.

Kilograms of rot in the intestines cannot but affect your health. A person who does not observe the time intervals necessary for complete digestion of food dooms himself to illness, bad feeling, which ultimately affects human life expectancy.
