Food digestion time
As practice has shown, not all people are interested in the question of how much food is digested in the stomach .
And I want to tell you that because of the lack of a clear idea of the importance of this issue, many people, without even noticing it, are driving their health into a dead end.
The idea is that different foods require different "attention" from our digestive system.
What happens to food after we swallow it? In order for the food to bring a person benefit and give the necessary energy, it must turn into chemical elements, which the body then absorbs. This process begins in the mouth when the saliva dissolves and the teeth grind the food.
Later, in the stomach, it is affected by acid and gastric juices. Coming out of the stomach, food enters the intestine, 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.
Table of time digestion of food in the stomach
If you drink water on an empty stomach, water immediately passes into the intestines.
Juices and salads
Fruit juices, vegetable juices and broths are digested for 15-20 minutes.
Semi-liquid (grated salad, vegetables or fruits) 20-30 minutes.
Watermelon is absorbed in 20 minutes.
Melons - 30 minutes.
Oranges, grapefruits, grapes - 30 minutes.
Apples, pears, peaches, cherries and other semi-sweet fruits - 40 minutes.
Mixed salads (vegetables and fruits) are digested within 20 - 30 minutes.
Raw mixed vegetable salads - tomatoes, leaf 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, the time is increased to more than an hour.
Cooked, steamed or steamed vegetables
Leafy vegetables - spinach, chicory, kale - 40 minutes.
Zucchini, broccoli, cauliflower, green beans, pumpkin, corn on the cob - 45 minutes.

Turkey - 2 hours (without skin).
Beef, lamb - 3-4 hours.
Pork - 4-5 hours.
Categories of food by the time of its digestion in the stomach
More specifically, all food can be divided into 4 categories according to the time it is digested in our stomach:
- the food that passes quickly (it is mostly carbohydrate food)
- average digestion time (this is mainly protein food)
- food of long assimilation (it includes fatty foods and a combination of fatty and protein foods)
- overly long in the assimilation of food and practically indigestible
Now let's describe everything in more detail and structure the information a little.
The first category includes: almost all fruits (except for bananas, avocados, and the like), vegetable and fruit juices (not mixed), berries, kefir.
All the above products do not linger in our stomach for more than 1 hour. For example, fruits pass into the intestines from the stomach within 40 to 45 minutes. In some situations, they can be in 35-40 minutes.
The second category includes: vegetables, greens, dairy products with the exception of cottage cheese and hard cheese, sprouts, soaked nuts and seeds, all dried fruits. All of them get into our intestines in approximately 1.5 - 2 hours.
The third category includes: cereals and cereals, nuts and seeds, which are not pre-soaked in water, cottage cheese and hard cheese, all types of mushrooms, legumes (if boiled), bakery products made from high-grade flour. Their time in the stomach is 2 to 3 hours from the moment they arrive.
And finally, group 4 includes: tea with milk, coffee with milk, meat (including poultry, and fish), pasta (except for those made from whole-grain flour or flour from durum wheat), all kinds of canned food. All products from the 4th group are digested very problematically, or are 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 yourself health - you need to eat as much as possible products that are digested for a short period of time. Thus, you save and your digestive system, and the body spends less energy on its processing.
- Avoid or eat at a minimum the food that belongs to 4 categories.
- It is not recommended to combine food and food products that have different digestion times in the stomach.
- If you have stomach or intestinal problems, eat only food from categories 1 and 2.
- In the evening, you can eat foods, too, only from categories 1 and 2.
Let's look at specific examples.
How much cottage cheese is digested? First you need to understand that at lunchtime, digestion is stronger. Accordingly, in order to fully understand: how much cottage cheese is digested - it is also necessary to take into account the time of its use.
For example, if you eat it at lunch - it will already go to the intestines in 2 hours. If you ate it in the morning or in the evening - the time increases to 3 hours and even more (for example, if you ate it before bedtime).
How much is a banana digested? Banana, as we all know, refers to fruits. Accordingly, the answer to the question of how much a banana is digested is very simple. As a fruit, it is ready for further processing in 45–50 minutes. If the banana is green, it will be assimilated for 10 minutes longer than a well-ripened one.
How much warm food is digested? Warm food in the stomach is digested for about 2-3 hours and only after that it enters the small intestine, where the stage of splitting of useful substances from food continues. Two to three hours is the optimal time to digest food in the stomach and break down proteins. This is the norm, since fermentation begins with the entry of undigested proteins into the small intestine.
How much cold food is digested? Cold food in the stomach is digested much faster: proteins do not have time to digest normally and go straight to the small intestine, whose function is based on the breakdown and absorption of carbohydrates, because it is in it that bacteria are responsible for this "event".
As a result of ingesting undigested food in the stomach (proteins) in the small intestine, proteins, of course, are not normally absorbed. In addition, the bacteria that live in meat products (proteins), begin to multiply, which leads to various types of discomfort in the digestive tract (bloating, gas, constipation, etc.).
Golden rules for excellent digestion
In order to be healthy and live long, it is very important to know and take into account the time of digestion in the stomach. According to doctors, a person who, while feeding, does not take into account the time of digestion of food, carries kilograms of rotting food, earns many diseases and shortens his life. For good digestion, you must consider the following key points:
- It is absolutely unacceptable to throw into the stomach, as in the "firebox", requiring different times for digestion products - that you put it additional and unjustified load. For example, a dish of potatoes and pork will be digested in about 5 to 6 hours, while separately consumed potatoes would be digested and go to the intestines within an hour.
- It is optimal to mix food of the same digestion time (vegetable salad, apples with pears, carrot and beet juice) - this only slightly stretches the time the food stays in the stomach due to the difficulty of selecting enzymes for processing compared to monofoods. This version of the "hodgepodge" is the most gentle for the body.
- The addition of oils, even in 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.
- Water, tea and other liquids should not be consumed if there is undigested food in the stomach - with this you dilute the gastric juice, complicate the digestion of food and increase the load on the gastrointestinal tract. In addition, along with the liquid in the intestine inevitably "slip" undigested products, which will long rot in it or wander.
- 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 start of processing with enzymes 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 protein breakdown), and only after that enters the small intestine, where the stage of splitting 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 bacteria found in meat products (proteins) begin to multiply and cause discomfort in the gastrointestinal tract (bloating, gas, constipation etc.)
