How much red caviar is digested. How much food is digested and what is the most favorable combination of products

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.

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.

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 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 put together 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.

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.
The second useful product in a row -cranberry. This berry is indispensable for colds - it has an antipyretic effect, kills viruses in acute respiratory infections. The use of these healing berries lowers blood pressure in hypertensive patients, strengthens the gums, 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, 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!

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 pre-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 figures 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.

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

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

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

Questions for a specialist

How much food is digested in the stomach: food table

The process of digestion of food lasts from 2 to 10 hours, sometimes up to 2 days. The duration of digestion is affected by the type of food, the presence of heat treatment, the time of eating, its quantity, the age of the person, as well as the individual characteristics of the gastrointestinal tract, the state of health of the digestive organs. In this case, the gastric phase - the breakdown of products in the cavity of the stomach - is usually 3-4 hours, but can be longer, up to 10 hours.

How much food is digested

The process of digestion consists in the breakdown of food into its simplest components - amino acids, sugars. Gastric digestion is carried out by gastric juice. It contains a mixture of hydrochloric acid and pepsin. Gastric juice breaks down crushed food into a homogeneous mass - chyme.

Food products differ in calorie content and digestion time. This must be taken into account when compiling a food menu. You must first - eat foods that are easily digested. And then - those that are absorbed for a long time.

Foods that are easily and quickly digested include fruits and fruit purees, juices, as well as vegetables, leafy greens, and salads. Most of them are absorbed within 15-20 minutes.

Easily digestible food

The fastest digestible product is plain water. It does not linger in the stomach and immediately enters the intestines. Liquid foods are digested more slowly. So, juice, fruit pulp, milk - split in the stomach from 15 to 25 minutes. Thus, liquid food - juices, compotes - are the fastest and most easily digestible products.

The assimilation time of watermelon pulp is comparable to the time of assimilation of juice or liquid fruit puree and is 20-25 minutes. Also, melon pulp is digested for a relatively short time - 30-40 minutes.

Half an hour of assimilation require almost all fruits. Oranges and grapefruits, grapes and cherries, apricots, peaches are digested in 40-45 minutes. At the same time, fruits with a more liquid consistency of the pulp are absorbed faster. And denser apples, pears are absorbed more slowly.

Also quickly, in 30-40 minutes, vegetables with juicy pulp are digested - tomatoes, cucumbers, sweet bell peppers, greens. Medium-density vegetables are digested a little longer - cabbage, radish, zucchini, broccoli. Their digestion time in the stomach is 40-50 minutes.

Vegetables with a dense structure, root crops, split in the stomach for about an hour. Carrots, beets, sweet potatoes, Jerusalem artichokes are such "long-digestible" vegetables. The time from splitting in the stomach is 60-70 minutes.

All of the above is true for the process of assimilation of raw vegetables. Their pulp contains a large amount of enzymes that are also involved in digestion. But boiled, baked, thermally processed vegetables are digested longer. Heat treatment deprives the products of most of the vitamins and enzymes, so the time for their splitting increases.

Products that digestion up to 1 hour are called easily digestible. In addition to the above vegetables and fruits, liquid kefir, fermented baked milk, and broth are among the quick-digesting products.

Note: it is important to know and take into account when compiling the menu - adding vegetable oil to vegetables increases the time of their breakdown in the stomach by more than an hour.

And now we will describe the features of the rapid assimilation of some products.

Banana

It differs from other fruits in high calorie content. On bananas, you can successfully gain weight, since each 100 g contains 90 kcal. At the same time, banana pulp is digested quickly enough. Due to the combination of natural sweetness and fast digestion, bananas are not recommended for diabetics.

How long does a banana take to digest? If the fruit is ripe, the digestion time in the stomach is 30 minutes. If unripe, green, then it will split 40-45 minutes. The prolonged digestion time of an unripe fruit is due to its more difficult digestion.

Apple

Persimmon

Contains more dietary fiber (fiber) than an apple. This means it takes longer to digest. How much persimmon is digested also depends on its ripeness. The pulp of ripe fruits is split in the stomach in 40-45 minutes.

Chocolate

Natural and sugar sweets, honey and caramel sweets, chocolate are also quickly digestible foods. At the same time, they are a source of a large amount of carbohydrates that enter the human blood rather quickly. All of the above is true for sugars without fats. If you add vegetable or animal fat to the sweet - sour cream, cream - then such sweetness will be digested for a long time.

How long does chocolate take to digest? Pure chocolate without additives, fillings, cream passes through the stomach in 20-25 minutes. But milk chocolate with filling, nuts - splits longer, up to 40 minutes to an hour.

"Average" products in terms of assimilation time

The average assimilation time includes those products that are digested from 1 hour to 3 hours. As a rule, they contain almost no fat, since the fatty components significantly lengthen the digestion time. These are cereal cereals, bread, as well as milk and vegetable proteins - cottage cheese, nuts, legumes. This also includes eggs and dishes based on them.

Protein food: cottage cheese

This protein is absorbed in the human body almost completely. How long does cottage cheese take to digest? Usually the time of its splitting in the stomach is 1.5-2 hours. But liquid dairy products - milk, kefir, are absorbed faster, in 40 minutes, and are easily digestible foods.

Grain food: bread, rice, buckwheat

Complete assimilation of cereals, cereals, bread, lasts about 6 hours. At the same time, the time of their splitting in the stomach is up to 2 hours. Such a long assimilation is explained by the need to break down, “disassemble” the food received into simple carbohydrates.

How much is buckwheat and rice digested? The process of digestion differs by 20-30 minutes. Buckwheat splits in 2 hours. Rice - is more "heavy", it is digested in 2.5 hours.

Bread - moves faster from the stomach to the intestines, but lingers longer in the intestinal cavity. Yeast bread causes an imbalance in the intestinal flora. It causes fermentation, delay in the evacuation of intestinal masses, as well as gas formation, bloating, incomplete digestion of food.

How much bread is digested in the stomach? Up to 2 hours.

Starches

Starch and starchy vegetables - potatoes digest longer than grain cereals.

So, the digestion time of potatoes in the stomach is 3 hours. However, jelly is a liquid food, which contains potato starch, is absorbed faster, about an hour.

"Heavy" products of long-term assimilation

Long digestible foods include those whose digestion time in the stomach exceeds 2 hours. These are animal proteins and vegetable animal fats.

How much meat is digested depends on its type. In the process of assimilation, the protein is broken down into simple amino acids, and this process takes several hours. Poultry and fish are digested faster. Slower - beef, lamb, pork. The meat of large animals is digested more difficult than poultry.

Fish, chicken, beef, pork

The time it takes for fish to break down in the stomach can be fast—a little over an hour—if the fish is raw and lightly salted. Boiled and especially fried fish are digested longer - up to 2 hours (boiled) and up to 3-4 hours (fried in oil).

Poultry is digested longer than fish. The time of its splitting in the stomach is about 2-2.5 hours - provided that the chicken or turkey is without cartilage and skin.

The maximum time of gastric splitting in beef (4 hours) and pork (5 hours - and this is only in the stomach, not counting the time for further absorption in the intestines).

Prolonged breakdown of protein components explains the effect of saturation. After a plentiful meat meal, a person does not want to eat for 6-8 hours, and animals after a successful hunt do not feel hunger for 1-2 days.

Features of digestion of animal protein

The peculiarities of the digestion of any meat include its ingredient to the splitting action of saliva. Thus, the protein enters the stomach without pre-treatment with enzymes - in contrast to carbohydrates, which are broken down in the mouth during chewing.

In the cavity of the stomach, the meat is also not completely digested. It contains difficult to digest components - veins, cartilage, skin.

The digestion time of meat products is long and not always complete. You can reduce it by the joint use of greens and vegetables.

Table - how much food is digested in the human stomach

In this article, we will consider digestion time various products . I think this will be interesting to many and everyone should have an idea about this.

If you will know food digestion time , then you can cook dishes that are normally digested in your stomach and will not poison the body with toxins from undigested food residues.

talking about food digestion time , we will understand the full cycle, that is, the period of time that is necessary for the products to be completely broken down into useful substances. Many gastroenterologists will tell you that digestion time even heavy meat products does not exceed 4-5 hours. But they talk about digestion time in the stomach. In fact, food is not in the stomach for more than 4 hours. After which she goes first to small intestine , where the assimilation process takes place, and then in colon for withdrawal.
The figures below are average values. The time of digestion and assimilation also depends on the individual characteristics of the body, on the diet, food composition, the amount of food eaten and on the compatibility of products with each other. So friends, let's take a look at which products pass through our stomach almost instantly, and which ones stay there for long hours.
Water - if your stomach is empty, then water passes immediately into the intestines

Digestion time of fruits and vegetables

Fruit on average, 30-60 minutes are digested. Energy and enzymes are almost not spent on the digestion of fruits.
Fruit and vegetable juices and vegetable broths- 20-30 minutes.
Semi-liquid juices, such as pureed vegetable or fruit salad- 20-30 minutes. For example, a glass of freshly squeezed orange juice will leave our stomach in 20 minutes after you drink it.

Roots- carrots, beets, parsnips, turnips, etc. - 50 minutes

Digestion timeh millet, cereals and legumes

Grain digestion time
concentrated carbohydrates- cereals and cereals. The time of digestion of cereals and cereals in the stomach increases dramatically. Therefore, it is recommended to eat fruits on an empty stomach, separately from cereals and cereals. A plate of ordinary porridge leaves the stomach only after 4-5 hours!
Brown rice, millet, buckwheat, cornmeal, oats, pelovka- 90 minutes

Soaked Nuts: 1.5 hours

Digestion timedairy products

Raw milk slowly leaves the stomach, pasteurized even more slowly and boiled even more slowly. High-fat milk passes through the stomach more slowly than low-fat milk.
Skimmed milk, ricotta, low-fat cottage cheese, cheese, homemade cheese - digested for about 90 minutes.

Fish– 45-60 minutes
Chicken- 1-2 hours (without skin)
Turkey- 2 hours (without skin)
Beef, lamb– 3-4 hours
Pork– 4-5 hours
On average, meat is digested in the stomach within 4-5 hours, and absorbed by the body for a very long time. Bacon is digested slowly, because of the fat it lowers stomach acidity. For most people, it is difficult to digest. Fat significantly prevents the release of gastric juice after eating, reduces absorption and delays the digestion process.

Digestion time fatty food

It can be either fat in its pure form, for example, lard, or just fatty meat or fish, ice cream, and so on. Fat greatly inhibits gastric digestion. Fatty foods take the longest to digest. By the way, fatty fried meat, such as barbecue, is digested up to 72 hours, while our body spends a lot of energy on digesting such food. A person who regularly eats meat carries in himself several kilograms of feces, which turn into toxins and release toxins that poison the body.
It is not important how long the food is in the stomach, but in what form, digested or not digested (digested or not fully digested), it will pass into the intestines, and what will happen to it next.
