How much pilaf is digested in the stomach. How long does it take to digest and assimilate different foods

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, therefore, filling the stomach with various foods 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 already at the initial stage of 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.

The older the 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 body of a seven-year-old child, compared with an adult, needs 2 times more time to process food. Upon reaching the child's body at the age of 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.

In the 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 with 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.

Physical activity - physical activity of 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 for a long time, bloating, heaviness occurs.

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 consume protein food in a warm form, in this form it will stay in the stomach longer - 2-3 hours, and all useful 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.

Simultaneous intake of food and water should be avoided. 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 lingers in the body for 60–90 minutes, but this will not lead to better absorption of 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 under the condition that the products were consumed separately. These numbers may vary slightly for different people.

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 a meat dish, discomfort cannot 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, poor health, which ultimately affects the life expectancy of a person.

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.

How many hours does a person digest food

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

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

Digestion time in the stomach:


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

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

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

What is absorbed the fastest (table)

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.

Category Products Time
Rapid absorption (carbohydrates) Berries, fruit and vegetable juices, fruits(except banana, avocado), vegetables

No more than 45 minutes.

How much fruit is digested - 35-45 minutes

Medium digestion (proteins with little fat) Eggs, seafood, poultry, dairy products (except cottage cheese and hard cheese)

About 1-2 hours.

How much fish is digested - 1 hour

Long-term absorption (complex carbohydrates) Potatoes, cottage cheese, hard cheese, cereals, mushrooms, legumes, bakery products, nuts

Approximately 2-3 hours.

How much porridge is digested - 2 hours

Not digested Canned fish, stews, pasta (from durum varieties), tea and coffee with milk, animal meat, mushrooms

More than 3-4 hours or simply displayed.

How much pork is digested - up to 6 hours

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

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

In the third situation, it will be especially difficult for the body to assimilate the incoming fuel due to fats, which create a film that repels gastric juice, and stretching the processing time of the “material”. As can be seen from the table, meat and mushrooms are digested the longest. Take this into account when planning a menu, especially for children: fast-digesting food is preferable for a child.

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 of general rules, following which will greatly facilitate the work of the digestive tract:

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

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

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

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

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

7. Cold food is processed faster and can lead to obesity due to a violation of the absorption process. The feeling of hunger returns faster, the processes of absorption and utilization are disrupted, the intestines undergo decay processes. 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. Keep in mind that the most favorable time for processing the “material” is lunchtime, so it is fashionable to quench the thirst for mixing incompatible categories without consequences. Breakfast and dinner do not differ in such activity, so try to select foods of the same digestion time and quick assimilation.

9. When asked if food is digested during sleep, the answer will be a call to simple logic. Night time is a period of rest and recovery for the whole organism, 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 best time for various products

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

Many are interested in how much rice porridge is digested in the stomach - the same as regular rice - 3 hours. The time for assimilation of semolina porridge is slightly less - 2 hours. Boiled corn takes approximately 2.5 hours to digest, depending on the ripeness of the cob. And the most easily digestible cereals, as you probably already understood, are familiar from childhood - an ideal quickly digestible porridge for children and adults.

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 much duck meat is digested? Approximately 3.3 hours
  • How many hours meat (beef) is digested does not depend on the part. Approximately 3.3 hours.
  • How many dumplings are digested in the stomach - 3.3 hours.
  • The digestion time of fat can exceed a day.

The rate of digestion of meat in the stomach also depends on the method of its preparation. For example, the time it takes to digest ground beef will be reduced if you add pureed vegetables such as zucchini or carrots when cooking ground beef patties. But jelly from pork legs will be digested for a very long time - more than 5 hours. Chicken jelly is digested a little faster - about 3-3.5 hours.

Seafood

  • How long fish is digested depends on the variety: low-fat (cod) will fit in 30 minutes, fatty (herring, salmon, trout) - 50-80 minutes. A hake is quickly digested in the stomach - no more than 2 hours.
  • How long do shrimp digest? About 2.3 hours.
  • Assimilation of sea cocktails will take approximately 3 hours.

When compiling a menu, do not forget about such a factor as the compatibility of various products.

Vegetables

  • How long does a potato take to digest? Young - 2 hours.
  • How long does a fried potato take to digest? Already 3-4 hours. Boiled - only 2-3 hours. How long does a baked potato take to digest? Young - about 2 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).

Now you know which vegetables are poorly digested: cabbage, fried potatoes, celery root will also take a long time to digest. The rate of assimilation of lean cabbage soup also depends on the time of assimilation of cabbage and will be approximately 3 hours. Why else soup can be digested for a long time: tough meat for broth, the use of too fatty a piece of meat for broth, a high content of vermicelli and long-digestible cereals.

Fruit

  • Consider kiwi. The digestion time will be 20-30 minutes.
  • How much an orange is digested - 30 minutes.
  • How many tangerines are digested - also 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.

There are other types of fruits that are digested for a long time by the gastrointestinal tract. For example, do you know how much persimmon is digested in the human stomach? Almost 3 hours! Therefore, you should not eat this product at night.

Animal products

  • How much milk is digested - 2 hours.
  • How long does curd take to digest? Approximately 2.5 hours. Is the cottage cheese low fat? About 2.4 hours.
  • How much cheese is digested - 3.3 hours.
  • I wonder how much kefir is digested? 1.4 to 2 hours (non-greasy - fatty).
  • The digestion time of ryazhenka will be 2 hours.
  • How long does yogurt take to digest? Approximately 2 hours.
  • For gourmets: how long does ice cream take to digest? The process takes 2.3 hours.
  • How long a boiled egg is digested - 2.2 hours. What about egg white? The same indicators.
  • How much fried eggs are digested depends on the volume. A dish of two hard-boiled eggs - 2-3 hours.
  • How long does an omelet take to digest? A little over 2 hours.

flour products


  • The time of digestion of bread in the stomach depends on the type of flour: from 3.1 hours (wheat) to 3.3 hours (rye).
  • The question of how much bread is digested is difficult. The product has a lot of fiber (100 grams = 4 loaves of rye bread), which is digested for a long time.
  • 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 the right ingredients at the right time to avoid overloading the digestive tract and causing fermentation, choose the right time. It's easy to be healthy.

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

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

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

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

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

The first category includes: 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 hour. For example, fruits pass into the intestines from the stomach after 40–45 minutes. In some situations, it can take 35-40 minutes.

The second category includes: 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.

The third category includes: cereals and cereals, nuts and seeds that are not previously soaked in water, cottage cheese and hard cheese, all types of mushrooms, legumes (if they are boiled), bakery products from high-grade flour. 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, meat (including poultry, as well as fish), pasta (with the exception of those made from whole grain flour or durum wheat flour), all types of canned food. All products from the 4th group are digested very problematic, or practically not digested at all.

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

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

The numbers below show how much time the products spend in the stomach and refer to people with a healthy digestive system when eating only one of the indicated products at a time.

In order to be healthy and live long, it is very important to know and take into account the digestion time of food in the stomach. According to doctors, a person who, while eating, does not take into account the time of digestion of food, carries kilograms of rotting food, earns many diseases and shortens his life.

1:1053 1:1063

For good digestion, the following key points must be considered:

  • It is absolutely unacceptable to throw into the stomach, as in a "furnace", products that require different times for digestion - by doing this you expose it to an additional and unjustified burden. For example, a dish of potatoes with pork will be digested in about 5 to 6 hours, while separately consumed potatoes are digested and would go to the intestines in an hour.
  • It is optimal to mix food of the same digestion time (vegetable salad, apples with pears, carrot and beetroot juice) - this will only slightly extend the time the food stays in the stomach due to the difficulty in selecting enzymes for processing compared to mononutrition. This version of the "hash" is the most gentle for the body.
  • The addition of oils, even to salads, lengthens the time spent in the stomach by 2-3 times, due to the effect of enveloping food, and the impossibility of its rational processing with juices and enzymes.
  • You can not drink water, tea and other liquids if there is undigested food in the stomach - this dilutes the gastric juice, complicates the digestion of food and increases the load on the gastrointestinal tract. In addition, along with the liquid, undigested foods inevitably “slip” into the intestines, which will rot or ferment in it for a long time.
  • If you drink water on an empty stomach, it immediately passes into the intestines.
  • Chew food thoroughly - this also speeds up the digestion process due to better grinding and the beginning of enzyme processing in the oral cavity.
  • Eat protein foods only in the form of heat - warm food in the stomach is digested for about 2-3 hours (which is the optimal time for the breakdown of proteins), and only after that it enters the small intestine, where the stage of breakdown of nutrients from food continues.
  • Cold food in the stomach is digested much faster, so proteins do not have time to digest normally and go straight to the small intestine, as a result of which the bacteria found in meat products (proteins) begin to multiply and cause discomfort in the gastrointestinal tract (bloating, gases, constipation). etc.)

For example, drunk water on an empty stomach immediately enters the intestines.
Freshly squeezed vegetable and fruit juices absorbed by the body in fifteen to twenty minutes.
Also, in twenty minutes the body is absorbed watermelon.
It takes the body half an hour to digest: salads (mixed, from vegetables and fruits), melon, oranges, grapefruits, grapes.
In forty minutes, fruits and berries are digested, such as: cherries, apples, pears, peaches, apricots etc.
It also takes forty minutes for the body to digest tomatoes, lettuce (red, roman, Boston, garden leaf), celery, yellow peppers, cucumbers, and various other juicy vegetables.

For the processing of root crops, for example, such as carrot or turnip the body will require about fifty minutes.
Avocado, eaten on an empty stomach is digested within two hours, since it contains a large amount of fat.
to digest vegetables that contain starch the body will need at least an hour.
Cereals that contain starch, such as: rice, buckwheat, barley etc., are digested from sixty to ninety minutes.
Legumes such as beans, lentils etc. the body assimilates in ninety minutes.
From an hour to two, the stomach will need to digest foods such as: soft-boiled egg, cocoa, broth, rice, boiled river fish and milk.

For digestion sesame, pumpkin, and sunflower seeds the body will take about two hours.
Almonds, pecans, peanuts, brazil nuts and walnuts our stomach will digest in two and a half to three hours.
From two to three hours, our stomach will digest foods such as: scrambled eggs, bread, hard-boiled eggs and boiled sea fish.
Boiled chicken and beef, rye bread, ham and potatoes will be digested for about three to four hours.
From four to six hours the following foods will be digested: peas, herring, mushrooms, fried meat.
