Nutrition rules
The first thing you need to pay attention to is the state of your teeth. If the teeth react painfully to cold or hot, to salty or sweet food, then this can be a manifestation of caries or hypersensitivity when exposed to the roots of teeth, with defects in their hard tissues, cracks or chips. All this is the reason for compulsory treatment to the dentist - poor chewing food is reflected in the work of the stomach.
When chewing food, saliva is released, and the enzyme , contained in the saliva , lends it bactericidal properties. For a day, a healthy person releases up to 2 liters of saliva. It contains enzymes that can break down carbohydrates and proteins in alkaline and neutral media.
Hydrochloric acid is released in the stomach, which creates a highly acidic environment. This is necessary to know, for, creating a very acidic environment in your mouth, you exclude the necessary work of the stomach.
Vegetables and fruits - the main sources of carbohydrates - should be thoroughly chewed in the mouth, thus contributing to their splitting.
People who badly chew food almost always have stomach problems.
When talking about eating, you need to know one more truth: more food is cooked with love and joy, as well as from the products that nature gives us. Do not eat in an excited, nervous state.
Speaking about nutrition, it should be emphasized that one of the costs of civilization is the creation of new products and, especially, sugar.
If you take sugar moderately, it's not very scary. However, as scientists have established, if you eat 50 g of sugar, then after 2 hours the concentration of insulin in the blood increases, increasing by 2-3 times.
In the experiment it was proved that with this addition of insulin, after only 30 minutes, the synthesis of cholesterol in aortic tissue is increased by 2 times.
The use of animal fat can not be excluded - it contains vitamin D. However, the basis of the diet should be vegetable food - fruits and vegetables.
This reduces the risk of cancer and slows the rate of atherosclerosis.
It has been found that the lower content of animal fat, sugar and restriction of table salt in the diet, but the greater addition of starch, vegetables and fruits to the diet reduces the risk of premature development of myocardial infarction, stroke and hypertension, as well as diabetes and cancer.
Optimal is the preservation of weight, which was in 20-25 years, if during these years the person was healthy.
The choice of an individual diet should be determined by individual characteristics, the nature of the person and family predisposition to certain diseases.
According to the famous physiologist KM Bykov, the causes of many pathologies of the gastrointestinal tract is the mismatch in the intake of food with the time when the body is ready to take it.
In addition, you need to know that within a day the need for food quantity in persons of different chronotype is different.
People of the morning chronotype - "larks" - after awakening like to have a good breakfast, and in the evening they have a light dinner.
People of the evening chronotype - "owls", on the contrary, in the morning they limit themselves to a light breakfast, and in the evening they prefer a thick dinner.
Scientists believe that every biological species during life can use only a certain amount of energy. This opinion in our time confirmed and IA Arshavsky. And the sooner this limit of energy is achieved, the shorter the life of an individual.
Throughout history, mankind is looking for a single, rational diet for all.
Various diets have been created to prevent cancer, cardiovascular and other diseases.
However, people have different types of metabolism, different heredity, different tastes and other characteristics.
All this allows us to consider that the generalized approach to nutrition is clearly insufficient. What is useful to one can be undesirable for another.
In recent years, interesting work has appeared on the study of the relationship of the blood group in humans and the predominant content of a protein supply.
For example, in group II, people prefer lamb or pork, while group I - beef and chicken. People with group III prefer rabbit.
With a pronounced tendency to develop hypertension and atherosclerosis, the decrease in cholesterol in blood plasma is advisable up to a certain level. Therefore, the medicine of the future is also an individual selection of a diet too.
