How much broth is digested. Everything you need to know about how food is digested

Digestion of food, depending on its type, takes from 15 minutes to 6 hours, however, these time frames have individual fluctuations. The maximum activity of the digestive tract occurs in the middle of the day, the minimum - at night, according to this, the time for digestion of food changes. In children and young people, digestion is accelerated, in the elderly it is slowed down. Slow down digestion and pervert its diseases and digestive disorders. Food combinations also affect the speed - if they have different digestion times, the total time spent in the gastrointestinal tract increases.

From several factors:

• chemical composition - carbohydrates are absorbed the fastest, their digestion begins already in the oral cavity, followed by proteins, and fats close the list, for the breakdown of which many enzymes and the entire surface of the small intestine are required;
• water content in the product - the more water, the faster the absorption;
• food temperature - cold food is digested several times faster;
• cooking methods - raw foods are digested within an hour, and the assimilation of complex dishes of multi-stage cooking can take many hours;
• food combinations - dishes from foods with approximately the same digestion time are quickly digested;
• uniformity of food intake and portion sizes - fractional meals with a break of no more than 3 hours and a volume of about 1 cup are recognized as the most physiological;
• eating habits without a feeling of severe hunger - if the previous portion of food is not digested, the absorption of the next one slows down, fermentation processes develop.

Easily and indigestible foods

By the time of assimilation, all products can be distributed as follows.

How to speed up the digestion time of food?

It is necessary to speed up digestion only when there are violations, and the doctor confirmed the presence of the disease. In all other cases, it is better not to interfere in the processes regulated by nature itself, so as not to harm yourself with rash actions.

If such a need still exists, you can use the following methods:

When I eat I am deaf and dumb

This saying is true in all cases. When a person eats, he should not do anything else. Nutrition is the most important process for sustaining life. Food is the "fuel" on which each of us lives. Everything that interferes with digestion must be set aside:

Food swallowed "under stress" cannot bring benefits. When a person is involved in emotions, whether positive or negative, the whole organism reacts to it. The heart speeds up, the lungs breathe faster, and the stomach and intestines contract. Normal digestion against the background of the scandal is completely impossible. Food is "stale", rotting begins with all the ensuing consequences.

What about in other countries?

In many nations, the laws concerning food are dictated by the peculiarities of the climate. The Jews were especially successful in this. Their food is divided into 3 types: meat, dairy and neutral - cereal and fruit and vegetable. In the kitchens of many restaurants, and some at home, there are 2 refrigerators - separately for meat and dairy products.

Before the invention of the refrigerator, the separate consumption of meat and milk protected Jews from food poisoning in the heat of the day. Over time, this acquired a religious consecration, but the principles remained unchanged.

For those who have slow digestion, it makes sense to adhere to this division. Meat and milk are digested in completely different ways, since proteins have a completely different structure, different enzymes and digestive juices are required. The simultaneous "loading" of the digestive system with heterogeneous proteins and fats can significantly disrupt digestion in those who already have a defect. Therefore, it is advisable to use meat and dairy food separately, mixing it only with neutral - cereals, pasta, vegetables.

You can also avoid complex gravies and sauces that contain a lot of superheated fats. It is convenient to bake meat with fruit - organic acids not only make it soft, but add flavor and perfectly replace the sauce.

It doesn’t take much to “tune” digestion - just don’t throw anything into your mouth.

Each of us wants to live happily ever after. And if you also have good health, then life would be just perfect. To fulfill these desires, it is important to know how much food is digested in the human stomach, table. It will be convenient to navigate the time of the next meal.

How food is digested

The digestive system works differently at different times in a person's life. Moreover, she begins her work even before his birth, and gradually slows down with age. The scheme for promoting products along the gastrointestinal cycle is the same in all ages. Without further ado, it looks like this: mouth - stomach - small intestine - large intestine - rectum. In self-care is important to lose weight and be healthy.

How much time is spent on this process largely depends not only on age, but also on the general condition of a person, the characteristics of his digestive system and the state of each internal organ in particular. How much food is digested in the human stomach, the table has average time data. That is, for someone in the body, this process will occur faster, for someone more slowly.

What can affect digestion time:

The temperature of the food being eaten. Cold food is digested much faster than hot food. The best is the time of digestion of warm food.

Processing methods for products. Raw, unprocessed foods are digested in a minimal time, and foods that take a long time to cook and stay in the stomach for a long time.

activity of the digestive system. She is most active in the middle of the day, that is, during lunch. This is probably why breakfast and dinner have a lighter meal.

The right combination (compatibility) of products. To alleviate the fate of the stomach, digesting your lunch, it should contain products that are excreted from the body in about the same time.

Example! To digest baked pork, your stomach will need to spend up to 5 hours, and kefir is enough for 20-30 minutes - and out. Which one can be read.

Time of digestion of food in the stomach (table)

Nutritionists advise not to eat until all the food has been digested in the stomach. This is good for health and for those who seek to bring their forms closer to ideal. By the way, will help to improve your weight and lose weight.

Note! There are many conflicting opinions about the “correctness” and “incorrectness” of products, the need for heat treatment or a raw food diet, as well as other aspects of proper nutrition. Therefore, how much food is digested in the human stomach, the table with the given data may differ from those indicated in other sources.

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

Digestion in the stomach in children and adults

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

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



Product types

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

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

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



Digestion time of individual foods in the stomach:

Water	Goes directly into the intestines
vegetable broth	Up to 20 minutes
vegetable juice	Up to 20 minutes
Fruit juice	Up to 20 minutes
Fresh vegetables and vegetable salads without dressing	Up to 40 minutes
Berries and fruits containing a lot of water	20 minutes
Pears, apples, peaches	30 minutes
Boiled vegetables	Up to 40 minutes
Corn, zucchini, all types of cabbage	Up to 45 minutes
Most root vegetables (except those containing starch)	50 minutes
Fresh vegetable salads with vegetable oil	Up to 1 hour
Egg	45 minutes
Fish	Up to 1 hour
Vegetables containing starch	1.5 to 2 hours

Legumes	up to 2 hours
poultry meat	2.5 to 3 hours
Various types of seeds	3 hours
nuts	3 hours
Beef and lamb	4 hours
Pork	5.5 to 6 hours



Digestion of individual foods in the stomach

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





Water

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

Fresh fruits

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

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



Dairy

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

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



Cereals and legumes

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

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

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. Processing low-fat varieties can take up to 3 hours. Fatty cheese made from whole milk will stay in the stomach for up to 5 hours.

Meat and meat products

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

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



poultry meat

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

Editor's Notes
approx. one: raw animal proteins are digested in a shorter time than those listed above for cooked/heated animal fats.
approx. 2: This digestion time is given for the ideal situation where you eat one food at a time, chew well, your digestive tract works efficiently, as, for example, after fasting. This is the digestion time for an optimally healthy person with a healthy eating behavior. For the most part, this data comes from the work of Dr. Gian-Curcio and Dr. Bass.
The digestion time for a normal diet, for people with suboptimal digestion who are low on energy, and for meals that are mixed from 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 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 has become a common guest on our shelves in recent years. One kiwi a day covers the daily requirement of vitamin C, which, as you know, strengthens the immune system, blood vessels, increases the body's resistance to all kinds of infections, and 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 a delicious and nutritious product with many beneficial properties. Raisins have a strengthening effect on the nervous system, help suppress anger, and strengthen 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 of 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!

Digestion of food means the processing of food in the stomach for a certain amount of time. Here the main process of food processing takes place with further direction to the sections of the large and small intestines. In them, it is absorbed to a greater extent. Fruits belong to the class of carbohydrates. They are distinguished by the speed of decomposition as a result of the general action of the alkaline component of saliva and the acid component of the stomach.

Features of the digestion of fruits

Now the opinion prevails about the need for separate intake of different types of products - proteins, fats and carbohydrates. The period of digestion of proteins and lipids in the stomach is equal to the time of their splitting. But one thing is how meat and dairy products behave in the stomach, and another thing is how persimmons or fruits that grow in temperate latitudes are digested.
Carbohydrates, which at first glance are easier to decompose into elementary components, require the separation of periods of digestion and assimilation. The reason is not just in the consistent use of food, but in different splitting rates. And this determines the possibilities of physiological processes in the endocrine and digestive systems. Interaction reactions are long. They begin with mechanical and enzymatic treatment with saliva. They end up in the large intestine. The duration of the processes is from 30 minutes to 7-8 hours. Everything that has not had time to be digested is in the large intestine for about 20 hours.

Important! Optimal fruit digestion time is determined by key factors:

• the composition of food products;
• the presence of oils of vegetable or animal origin;
• simultaneous use of water, tea, other liquids;
• thoroughness of chewing.

The simultaneous use of the first and second courses, and then, immediately after them, fruits is not welcome. In this case, carbohydrates are retained in the stomach and reactions begin with the release of gases. It is allowed to mix food with apples, pears, carrot-banana mixture.

The digestion time of an apple in the stomach is like that of a pear. Similarly, carrots and bananas are herbs with a longer processing time than other fruits. The reason for this selection is the need for the body to produce similar enzymes.

Vegetable oil is not added to fruit dishes, but together with some vegetables it makes the diet more varied. This is especially true for children who are sick people. Therefore, how many hours a banana with cereals is digested depends on the type and quality of the latter. It is known that sunflower oil prolongs the absorption of plant foods by 2-3 times.
