The stomach is an organ with a length of 25 cm. It also can receive four liters of solid or liquid food. It was created for mechanical degradation, but also for chemical welding of food. The walls of the stomach consist of a multitude of folds or spine.Inside of the stomach covers the thick layer of mucus.

When this protective layer would not exist, the stomach would be punishing itself. Gastric juices would warn him along with food. The lower part of the stomach is the so-called. Pylorus (hole) to bring the digested food from the stomach into a twelve-tube hose.

It is equipped with a circular, thick layer of smooth muscles that control the release of gastric contents through the pyloric opening into the twelve-tube hose and at the same time prevents the return of stomach contents back.


What happens in the stomach while eating?

The stomach processes food in three phases.The first is chemical, the second occurs in the peristalsis.Muscle contractions that make the mixing of contents – food in the stomach. And the third stage involves moving the cooked food.

First, the upper sphincter (the type of muscles in the upper part of the stomach) closes and secretes gastric acids, the most effective of which is hydrochloric acid, which is a very strong solvent and is used in industrial production for the dissolution of metals.

The acids slowly concentrate and surround the food, which lasts about forty minutes. Then, the second phase of welding follows, the stomach walls begin to collect and wider, in order to ensure good mechanical crushing of food.

When all the food in the stomach reaches the same pH value and is equally warped, the third stage of digestion is reached – the transfer of food in small quantities into the duodenum. Under normal circumstances, this process lasts four hours, while digestion of very fat food lasts up to six hours.

The stomach needs a REST, and after the digestion process, we should give it at least one hour of rest. Therefore, our recommendation is to have an optimum break of at least five hours between the main meals (from the end of one to the beginning of the second).

By observing the digestion process using an RTG image, doctors have come up with shocking knowledge. A man who after a regular breakfast every two hours eats a few chopsticks of chocolate, after 13.5 hours in the stomach has more than half of the contents of breakfast.

In the second study, students received cereals, toast, fruits, and eggs for breakfast. Special tests have confirmed that after four hours students have empty stomachs. For several days students received the same breakfast, and then, on another occasion, they gave them another sandwich with peanut butter or a piece of melon cake with milk after two hours.

The result showed that even after 6-9 hours part of breakfast was still in the stomach. One day, after breakfast, they gave two times a day for a bunch of chocolates and repeat the same afternoon. The results showed that even after 13 hours after breakfast, some of the contents remained in the stomach.


What happens when two hours after a meal in a stomach comes new food?

Thanks to the arrival of new food, the pH of the stomach environment immediately change. The stomach stops its activities and re-emerges all three stages of digestion. From concentrating digestive juices, through peristaltic to leaving digested food from the stomach. The food that was previously flushed again goes through all three phases.Similarly as when we stop the washing process in the washing machine. We add even more and we include the program from the beginning.


What happens to the old, but partially cooked food?

In the food, toxic fermenters and other chemicals – aldehydes, alcohols, amines and esters affect the brain, liver, kidneys and other sensitive tissues, are starting to form. The productivity decreases and the person feels a bit stunted, has problems with concentration, and can become irritable.

 As a result of the fermentation of the previous food, a situation similar to that after drinking alcohol is created. The constant presence of food in the stomach forces the stomach to produce large amounts of acid and digestive enzymes.They dissolve not only food but also gentle mucous membrane of the stomach walls. Over time there is inflammation – gastritis and stomach ulcer.

When eating between main meals, an acid reaction is maintained in the mouth for a long time. This later LEADS Te formation of caries. For two hours after a meal, there is an outflow or rupture of minerals from the teeth (so-called demineralization). And only after the expiration of that period, minerals are returned (remineralization).

Snacks and snacks also contribute to overweight and obesity. Especially because sweet and fat foods are commonly consumed between main meals.

After the meal, triglyceride levels are also increased. As a result, increased adherence of platelets increases the risk of blood clots (infarction, ischemic stroke).

Each meal stimulates the pancreas to produce insulin. If too often it produces insulin, it is overloaded and can cause low blood sugar – hypoglycemia. This may be the first symptom of diabetes, which is sometimes apparent a few years later.
