The balanced food is not only guarantee of physical and intellectual activity of a human body, but also a necessary element for its existence. Process of digestion of food is a work of many internals.
The main objective of absorption of food is not esthetic appointment and satisfaction of flavoring addictions of the person, and need of maintenance of physical shape. In the presence of any diseases, first of all change a food allowance to improve the general health. It is caused by the fact that the diet and competently picked up diet are a basis of successful recovery.
Consumption of food includes process of a metabolism and energy (on the movement, a conversation, breath, thinking, a dream). The more the person spends energy during the day, the above there has to be a caloric content of the eaten dishes daily. Food is "fuel" for a human body. Also expense of energy depends on age of the person.
It should be noted that the amount of the consumed food has to correspond to physical characteristics (age, sex, weight category, the state of health, etc.). The lack of food leads to organism exhaustion, and overeating negatively affects work of internals, digestion process is broken, load of a cardiovascular system raises, body weight increases. For the person it is very important to chew carefully food, otherwise the insufficient amount of saliva is distinguished. It leads to increase in load of a stomach, deterioration in process of digestion and possible overeating. It is expedient to chew food slowly that there came the gradual feeling of saturation. The best digestion is promoted by the use of liquid which softens food and allows to pass with ease on digestive ways. It is also very important to eat at the same time as the organism, as a rule, is guided by rhythmical work. Meal at different times forces it to reconstruct and to adapt constantly to the new mode.
