It is noticed that a solid portion of fries with meat ensures long-term heaviness in the stomach, and after eating fruit salad after 30 minutes there is a feeling of hunger. So what foods are easiest to digest and that can slow down this process?
The easiest to digest fruits, vegetables and juices. And, of course, water. It is therefore recommended to start the meal with fruit and them it and finish. Particularly useful in this regard, the apples – they are two times increase the speed of assimilation of food. Among the easiest fruits to digest watermelon, because 80-90% of it consists of liquid. Cooked and eaten fruit salad from oranges, melons, grapefruits and grapes you're hungry after half an hour. The same applies to eating salad of peppers, celery, cucumbers, lettuce and tomatoes.
Most quickly the body processes foods rich in easily digestible carbohydrates. We are talking about sweet cherry, cherry, bananas, persimmons and figs. A little longer time to digest leaving the stomach and intestine into candy, jam, sugar, honey, jams, jellies, cookies, cakes, pastries and sweet drinks. The easiest in your stomach is processed and milk products: yogurt, cottage cheese, yogurt, fermented baked milk, etc.

Other products are heavier and slower to digest, but this process can be greatly accelerated, if you follow certain rules. First, you need to chew your food and to sit down 5-6 times a day. Secondly, there is a need in a calm atmosphere and do not mix in one meal the elements with different time of digestion.
What does it mean? This means that if you are in a vegetable salad add a little fruit, this does not change the speed of assimilation of food, but if you're going to sunflower oil, the time of digestion will increase in two times. And if you're going to drink this "mix" with water, the liquid will push nezapravlenny food in the intestine, where it also will not have time to be fully absorbed and released with feces. To do so is impractical because the water dilutes the gastric juice, making it less concentrated, which ultimately affects the quality of assimilation of food.
That's why nutritionists advocate a separate food, not recommending to use both products rich in fats with foods rich in protein; foods rich in glucose, with dishes rich in protein etc. the same applies to the combination of starch and sugar, and milk for all other products. Ie your stomach is the easiest to recycle food that is a member of one group at the speed of digestion.
