How much is buckwheat digested?
When planning separate meals and other types of therapeutic or health diets, an important place is taken by taking into account the time of digestion and assimilation of various products. Many nutritionists recommend not mixing food with different expected residence times in the stomach. At the same time, cereals from different cereals occupy an important place in a healthy diet, so it is worth considering how long buckwheat is usually digested.
Digestion process
In medicine, it is generally accepted that the process of digestion of food begins in the oral cavity during chewing. After all, saliva contains a number of enzymes that cause the beginning of the breakdown of complex substances that make up food into simpler ones. Although all the components of food are finally broken down only in the stomach, because in it the products experience the complex effect of hydrochloric acid and digestive enzymes, the most important of which is pepsin. It is this substance that is responsible for the decomposition of proteins contained in food into amino acids.
At the same time, the fact that Pepsin only works in highly acidic environments. And such an environment inside the human body exists only in the stomach. Already in the next link of the digestive system after the stomach, namely in the duodenum, the environment becomes slightly alkaline, which leads to the termination of the action of pepsin. Therefore, although food, moving through the intestines, is partially affected by intestinal enzymes and microflora, the stomach still plays the most important role in digesting food.The role of the intestine is reduced to the assimilation of food, that is, the absorption of food components useful for the body into the bloodstream.
Total food spends in the human body:
- a few minutes in the mouth and esophagus;
- from half an hour to 4 hours in the stomach;
- up to 8 hours in the small intestine;
- up to 20 hours in the large intestine.
What affects the duration of assimilation
The most important factor on which the duration of the stay of food in the stomach depends is its composition. Carbohydrates break down the fastest in the stomach, proteins usually take a little longer to process, and fats resist the effects of acid and enzymes the longest. In addition, the presence of gluten and fiber in it affects the duration of digestion of food. Gluten binds pieces of food together, forming large clumps that can take a very long time to digest. Well, fiber itself is almost not digested.
In addition to the composition, it greatly affects the rate of processing in the stomach and the state in which the food got inside it. Thoroughly chewed food is digested much faster than the one that enters the stomach in large pieces. Cold food is usually digested faster than warm food, and raw food is often digested faster than the same cooked food. This is important to take into account when eating protein foods, since proteins, due to the termination of the action of pepsin in the small intestine, do not break down, but instead begin to ferment. Therefore, a meal consisting mainly of protein should spend at least 2 hours in the stomach, which means It is best consumed warm, not cold.
The acidity of gastric juice greatly affects the digestion process - the higher it is, the stronger the pepsin acts and the faster the products decompose under the action of acid.Therefore, drinking large amounts of water along with food can prolong its absorption for some time. Finally, the residence time of food in the stomach depends on the time of day.
This process lasts the longest at night, and at lunchtime, products usually do not linger too long in this part of the digestive system.
Food groups by digestion time
Depending on the composition, four main groups of food products can be distinguished according to the rate of assimilation.
- Water - enters the intestines without delay.
- Fast-digesting food that spends about half an hour in the stomach. It includes all berries and other relatively soft and juicy fruits, such as melons, peaches, grapes and watermelons. This group also includes fruit juices, kefir, honey, chocolate and confectionery (cakes, pastries, cookies). Thus, this group contains products consisting mainly of "fast" carbohydrates. In addition to them, this group also includes soups and tea, which can be digested up to 40 minutes.
- Products of the average assimilation period, which are in the stomach for one and a half to two hours. This group includes fleshy fruits (apples, citrus fruits and bananas), vegetables and herbs, fish dishes, dairy products (except cottage cheese, cheeses and kefir), nuts, dried fruits, chicken dishes, chicken (and quail) eggs, boiled rice. It is easy to see that this group includes mainly protein foods.
- Products of long digestion, which are in the stomach from three to four hours. These include cereals from various cereals (including buckwheat), boiled legumes, cottage cheese, most types of bread. This group includes foods of a complex, predominantly protein composition.
- Products with a very long assimilation period, which include all fatty foods (lard and butter), meat (except chicken), all kinds of canned food (including those obtained by fermentation and pickling), pasta (except those made from durum wheat) , mushrooms, tea and coffee with milk. Food from this category passes into the intestines only after 4 or even 5 hours in the stomach.
The benefits and harms of buckwheat
Buckwheat porridge boiled on water has the following BJU formula:
- up to 60% carbohydrates;
- up to 13% proteins;
- up to 4% fat.
The calorie content of 100 grams of the product is about 320 kilocalories. In addition, buckwheat contains a large amount of iron, as well as potassium, zinc, calcium, phosphorus, molybdenum, iodine, fluorine, cobalt and other useful trace elements. Buckwheat is rich in vitamins, especially group B:
- B1 it contains up to 0.5 mg / 100 g;
- B2 - up to 0.2 mg / 100 g;
- B6 - up to 0.4 mg / 100 g.
In addition, 100 grams of buckwheat contains up to 4.5 mg of vitamin PP. Finally, the composition of this product also includes substances that reduce cholesterol levels.
This product is contraindicated only for persons with intolerance to its constituent proteins or starch.
Features of the digestion of buckwheat
It is easy to see that boiled buckwheat porridge, like other cereals, falls into the group of products with a relatively long digestion time. This particular product usually leaves the stomach within one and a half to 3 hours. At the same time, the indicated period is valid only for buckwheat boiled in water. The presence of fatty milk and a large amount of butter in the composition can increase the digestion time of buckwheat porridge, increasing it to a period of more than three hours.
Thus, it would be best not to combine buckwheat porridge with either very quickly digestible food (mainly carbohydrates) or very long digestible (mainly fatty and complex protein). In terms of diet optimization, buckwheat porridge will be the best side dish for chicken breast or boiled egg.
