Editor's Notes
approx. one: raw animal proteins are digested in more than a short time than that given above for prepared/heated animal fats.
approx. 2: given time digestion is given for the ideal situation where you eat one food at a time, chew well, your digestive tract works effectively, as, for example, after fasting. This is the digestion time for optimal healthy person with healthy eating behavior. For the most part, these data are taken from the work of Dr. Gian-Curcio and Dr. Bass.
Digestion times for normal diets, for people with suboptimal digestion who are low on energy, and for meals that are mixed with a large number of ingredients (not assembled in right order), 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 the stomach with a senseless load in the form of some apple eaten between lunch and dinner. Fast-digesting foods give a person fast energy, digested slowly - a long feeling of satiety. Everything that is not included in the digestion time described below is digested even longer.

Useful products that deserve more attention.

There are a number of products that we very rarely or never buy. Let us recall at least those vegetables and fruits that our mothers and fathers forced to eat, but we stubbornly refused. It's a pity! They help to improve 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 is last years became a regular guest on our shelves. One kiwi a day covers daily allowance 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, potassium mineral salts and fiber, which helps to eliminate cholesterol from the body and normalizes digestion.
Second useful productcranberry. 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, enhances the secretory activity of the pancreas.
Raisins are delicious and nutritional product, has many useful properties. Raisins have a strengthening effect on nervous system, helps to suppress anger, strengthens the heart. Raisins contain substances that stop the growth of bacteria that cause tooth decay and gum disease.
Ends our list broccoli. This is an excellent supplier of vitamins C, PP, K, U and beta-carotene. ascorbic acid(vitamin C) in broccoli is almost 2.5 times more 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 terms of not only mineral salts, but also protein. Even for broccoli, the fame of a famous cancer fighter was entrenched - 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 some 30 kcal per 100 g!

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? For food to benefit a person and give the necessary energy, it should 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 maintaining 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 to: cereals 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 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 much as possible. more products, which 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 for 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, lettuce (romance, 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 food, like husked rice, buckwheat, millet, cornmeal, oatmeal, quinoa, Abyssinian panicles, 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

Dairy
– Skimmed milk, skimmed homemade 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 small intestine, where the splitting step continues useful substances from food.

Two or three hours 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 it is digested much faster in the stomach: proteins do not have time to be digested 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 different foods are 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 the drinks drunk will be digested, let's take a closer look at the speed of digestion of all foods separately and consider how many hours are digested various food(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 different category 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.
• large meat cattle absorbed 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 for a 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.
• Products with high content it is better to use protein 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 do not have time to be digested in the stomach and are sent to the intestines, which can lead to backfire(disorder of the gastrointestinal tract, 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 digested and bring more benefit body, when they are not filled with oils (vegetable, olive), which prevent them from breaking down in the stomach (covering with a “protective” film).

We hope the table indicated in the article helped you find answers to questions such as how much oatmeal is digested in the stomach on water, sauerkraut, canned corn, fat-free cottage cheese, dumplings, chewing gum, bacon, fish, meat, bread, apple, 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 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 development, restoration and protection of cells are 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 along small intestine with parallel splitting, 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 absorbing the received elements and using them to replenish energy needs, regeneration of cellular tissues, maintaining 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.

It became clear how much food is digested in the stomach. The table reflects exemplary product grouping vectors, representing 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 various processing and cooking 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. Diluting undigested food with any liquid will reduce concentration gastric juice, will complicate the processing of the "material" and clog the intestines with undigested residues subject to fermentation.

6. Boiled and fried foods lose part 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. In particular, this rule applies to protein foods, which should be digested for at least 4 hours, and leave the body cold in 30 minutes.

8. Consider what is most auspicious time for the processing of "material" - lunch, so that the thirst for mixing incompatible categories can be quenched 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.
• Digestion time 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 excrete the right 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.

• 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 sea ​​cocktails will take approximately 3 hours.

Vegetables

• How long does a potato take to digest? Young - 2 hours.
• How much is digested fried 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.
• How long does a cucumber take to digest? An average of 30 minutes (like tomatoes, lettuce, peppers, herbs).
• Vegetable corn is not digested for more than 45 minutes (cook without oil).

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

• 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 a boiled egg is digested - 2.2 hours. BUT 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 for eating, combine ingredients that are right on 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 the methods of preparing 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 residues food.

Speaking of digestion, they usually mean a 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 heavy meat products, the 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 human, individual features 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 finished products. Assimilation 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, how exactly a person prepares his food. So when cooking or frying food, its original structure, characteristic 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 periods of morning and evening meals, a person needs to spend more body resources on the same process.

4. Mixing food is one of the most important factors for digestion time. Determined that different products 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 of the human body. In case of violation temperature regime the epithelial tissue of the internal organs begins 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. Drunk after a meal, even a glass cold water can do a lot of damage. 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, the person gets into 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 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 secretes big portion acids 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 subject to additional processing when cooking. 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 of separate nutrition

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, such an 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.

Meat is one of the main products in daily diet. The digestion of meat human body occurs according to a special mechanism. Food of animal origin contains protein, minerals and vitamins that the human body needs. But each type of this product has features that are worth knowing.

Composition and properties

Meat is rich in proteins, fats, carbohydrates, cholesterol and essential amino acids. The composition of this product contains trace elements such as iron, sodium, zinc, magnesium. And also in meat food there are vitamins of groups A, B, E, D, which regulate the functions of neurotransmitters, thereby guaranteeing the working capacity and activity for a person. These substances are essential for the proper functioning of the body.

Meat contains proteins foreign to the human body. When using this product in large quantities, the natural intestinal microflora is disturbed.

Animal products can and should be included in your diet. Only they should be fresh and in moderation. The benefits of meat depend on how it is processed. Nutritionists do not recommend eating fried and smoked meat, it is better to bake or cook the product. Any meat product is recommended to be eaten simultaneously with vegetables or porridge, so that the absorption of the product will be complete.

Digestion process

When it enters the mouth, the product is subjected to mechanical processing - chewing. The more thoroughly the food is chewed, the faster the digestion process will be. Food is coated with saliva, which is characterized by bactericidal properties. After swallowing the crushed food, it moves to the stomach. By using of hydrochloric acid product fibers are oxidized and more easily broken down by enzymes. Under the influence of pepsin and trypsin, the protein is broken down into amino acids.

Next, the lump falls into duodenum, there it is affected by bile and pancreatic juice. In the small intestine, proteins are broken down and fats are absorbed. Under the influence of enzymes, amino acids and vitamins enter the bloodstream. The rest of the food moves into colon. There, the assimilation of useful nutrients takes place, which then spread to all cells and ensure the maintenance of the body's vital functions. The large intestine absorbs minerals needed for normal functioning person.

Types of meat and digestion time

Meat is usually divided into 2 groups:

• Diet varieties:
  • rabbit meat;
  • chicken;
  • beef;
  • turkey.
• Fat varieties:
  • pork;
  • mutton.

Diet varieties digest faster. Assimilation of the fatty type of this product is considered difficult for the body and can cause stomach discomfort. But each type of meat has its own characteristics:

• Rabbit meat. It is considered the most dietary. Rabbit meat is hypoallergenic, so it is given to young children. The human body absorbs it by 90%. Rabbit meat contains a small amount of cholesterol, it is rich in minerals, vitamins and fats. Contains an omega-3 substance that promotes brain activity. The digestion period is a little over 3 hours.
• Chicken. The most common type of meat product. Often used in the diet of athletes. Contains a lot of protein balanced composition amino acids, lean. The speed of digestion of chicken meat depends on its variety, but on average it is 1.5 hours.
• Turkey meat. Very similar in composition and properties to chicken, but contains a large number of macro- and microelements and low-calorie. Digestion of turkey takes longer than chicken, more than 2 hours.
• Beef. Beef contains amino acids, protein necessary for the human body. This meat is rich in zinc and iron capacity. The digestion time of beef takes 3-4 hours.
• Pork. Contains many minerals and vitamin B group. It contains fat and is more difficult to digest by the body than other types. Therefore, in diseases of the gastrointestinal tract, pork is excluded from the diet. Eating a significant amount of pork leads to obesity. In the human body, such a product is digested for about 5 hours.
• Mutton. Contains little cholesterol big number vitamins. Fatty substances are less than in pork. But despite this, lamb is harder for the body to digest, the process is more than 3 hours. Therefore, people with diseases of the stomach lamb is contraindicated.

The amount of meat consumed is determined by the type of human activity. People who are actively involved physical labor and children are advised to use more protein. And the average person is normally enough for 70 grams per day. Therefore, you should not eat meat products every day, 3 days a week is enough. On other days, it is good to eat dairy products or fish.

How much food is digested in the human stomach? Many do not think about it, but it is very important point. If you choose the right products, you can ease the work of the stomach, and, conversely, unsuccessful combinations can lead to health problems.

Digestion of food, general numbers

How much food is digested in the stomach? How many hours does it take? It depends on the food that a person has eaten, but if we take average values, then from 0.5 to 6 hours. But there are two different processes. This is "digestion of food by the stomach", the amount of time that food bolus stays in the stomach. And the second concept is “digestion of food”, that is, its complete processing when it is split into chemical elements. The assimilation of digested products can last much longer: it moves through the small intestine for at least 7-8 hours, where it is split, and remains in the large intestine for up to 20 hours, that is, everything takes more than a day.

Categories of food digestion

How much food is digested in the human stomach? There are four main categories:

1. Foods that are digested fairly quickly.
2. It takes an average amount of time.
3. Food that takes a long time to digest.
4. Food that can be digested for a very long time and almost not digested.

Which products belong to which category?

Rules for compiling a diet

We figured out how long this or that food is digested. Why is this needed? To properly compose your diet. Thinking through the menu for the next week, it is advisable to follow the following rules:

1. Try to include foods from categories 1 or 2 in your diet. They digest much faster. This means that your digestive system is not overloaded, the body spends less energy on digestion, it is spent on something else, no less important.
2. People who have gastrointestinal diseases are also better to choose light food, which is absorbed much faster, that is, from categories 1 and 2.
3. In the evening, it is also desirable to eat the food that belongs to these categories. At night, the human body rests, including its gastrointestinal tract, so part of the food will remain in the stomach until the morning, and by that time it will have time to ferment.
4. Do not eat foods from category 4 too often.
5. If you are compiling a menu, try not to mix foods that differ greatly in digestion time, as you overload the stomach.
6. Remember that if you put in food various oils, for example, eat a salad with sunflower oil, the period of digestion of food increases by about 2-3 hours.
7. If you expose products heat treatment, that is, before you eat boil or fry, their original structure changes, as does the digestion time, it increases by 1.5 times.
8. Many people like to drink food. If the food has been diluted with any liquid, then the concentration of digestive gastric juice is reduced, so food processing may also take longer.

How long does a particular food take to digest?

Sometimes it is important to know exactly the time of digestion of food in the stomach, namely, exactly how many hours this or that food is digested. Let's talk about this in more detail, in the form of tables.

What does digestion depend on?

We told how long a person can digest food. But these are general figures, in the human body everything is much more complicated, the food that has entered the body can be digested both faster and slower, it depends on the amount of food, and on the quality, and on many other factors. What exactly influences the process of digestion:

1. The well-being of a person, the performance of the organs of his gastrointestinal tract, whether gastric juices are secreted correctly, and so on.
2. Whether he is hungry or full. If a person has a good appetite the food will be better digested. When he eats not because he is hungry, but because. That you need to somehow spend time or because of other reasons, food is digested longer.
3. The amount of food eaten. Many experts say that you can not overeat. If a lot was eaten, the body is overloaded with work, the food is absorbed worse.
4. The speed of metabolism. It depends on the person's gender and age. From the age of 25, metabolic processes begin to slow down.

There are other factors that affect these processes, including the way food is cooked, the characteristics of the human body, its habits, and so on.

If you want to stay healthy, you should follow the basic rules for nutrition, among which there is a rule about correct selection food. Try to eat foods that are in the stomach for the same time, eat light food, do not drink food, and then you will have much less problems with health.

It takes a certain amount of time for the body to get useful substances from the consumed products. Gastric juice is unable to instantly break down what has entered the body. How much food is 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 various food leads to decay of its residues, toxins and toxins accumulate in the body.

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

Effect of age and sex on duration

The duration of the process of digestion of food 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 for digestion of food approaches the same values ​​as for an adult.

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

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

Secondary factors influencing the processing process

The following factors affect how long food stays in the stomach:

• Thermal processing of products. In the process of cooking, some of the nutrients are lost, and the digestion process increases.
• Dish temperature. Food eaten hot is able to linger in the stomach a little longer, in the cold - it will quickly enter the intestines.
• The best option is warm food.
• Meal time. Foods eaten at noon are digested and excreted from the body faster compared to morning and evening meals.

Compatibility of the ingredients of the dish. In order to avoid unnecessary stress on the organs, the food used for cooking should be digested by the body in approximately the same time. Subject to this rule, the duration of food in the body will not differ much from the time of digestion when separate meals. The presence in the meal of a component with a long splitting period leads to a delay in the entire meal in the stomach.

Exercise stress - physical activity a person after a hearty meal helps to slow down the digestive processes.

Snacks during physical work should contain mainly foods containing carbohydrates. Such food is quickly digested and will not cause heaviness. If food is digested long time, there is swelling, heaviness.

In the process of digestion, an important factor is the rate of absorption of nutrients, and not the stay of food in the body.

All products should be chewed thoroughly, manipulation contributes to better processing and absorption of food.

It is more useful to eat protein food in a warm form, in this form it will stay in the stomach longer - 2-3 hours, and all healthy proteins will have time to break down to the state necessary for their further digestion in the intestine to amino acids. If you do not adhere to this rule, the stomach will not have enough time to digest them, 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 splitting process is carried out under the action of saliva swallowed with food.

Should be avoided simultaneous reception food and water. Under the influence of diluted gastric juice, food is digested longer, the quality of digestion decreases. Water promotes the penetration into the small intestine of food that has not gone through the entire process of digestion. Such food does not break down and is not absorbed, therefore it begins to rot. Together with food, bacteria 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 whole ones.

The use of oil in the preparation of vegetable dishes prevents the breakdown of products in the stomach due to the fact that it covers them with a greasy film. Food stays in the body for 60-90 minutes, but by better assimilation it won't bring food.

An example of calculating the duration of the digestion of products

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

The figures given in the table for the duration of the digestion of food are average values ​​​​and are valid provided that the products were consumed separately. At different people these numbers may vary slightly.

Subtleties of eating

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

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