What is nutrition?

In the eyes of a dietitian, many people in our time, lose all reason when it comes to the consumption of food and beverages. Power in itself serves the purpose of maintenance metabolism, but does this mean that eating, every time a person has to take care of metabolism, rather than to satisfy hunger or catering requests? And what a layman would know about such a balance in your body?

We know that we must eat to live, not to live to eat! Satisfaction of food a person can get and keeping elaborate diet. In this respect, we perhaps might envy, and our remote ancestors who lived "closer" to her and the natural environment. Now, all rely on modern culture, requiring more and more consideration of factors that affect the human body. Food culture in our time developing on the basis of scientific principles.

Pokrovsky), if we take 100 grams of protein per unit , the optimal ratio of B: F: V (by weight) should be 1:1:4, with employment in heavy physical labor - 1:1,3:5. With a sedentary lifestyle (eg, employees of the institutions, cabinet "hermits") - 1:1,1:4,1.

Distribution of food intake during the day (the energy value, composition and weight).
