Nutrition is the science that studies the physiological and metabolic processes that occur in the body with food intake.
Many common diseases and their symptoms often can be prevented or alleviated with a certain power; for this reason, nutrition science tries to understand what specific dietary aspects that influence health.
The purpose of nutrition science is to explain the body's metabolic and physiological response to the diet. The human body is made of chemical compounds such as water, amino acids (proteins), fatty acids (lipids), nucleic acids (DNA/RNA) and carbohydrates (e.g. sugar and fiber).
Adequate food is which covers:
• Power requirements through the metabolism of nutrients such as carbohydrates, proteins and fats. These energy requirements are related to basal metabolic expenditure, expenditure by physical activity and diet-induced spending.
• The needs of non-energy micronutrients like vitamins and minerals.
• The proper hydration of the consumption of beverages, especially water-based.
• Sufficient dietary fiber intake.
Types of nutrition in human beings.[

• Heterotrophic nutrition is that those organisms that need others to live carry out.

In the middle of the pyramid are vegetables and fruits, which help power most natural and without side effects. To ensure that you get more than half of our calories from complex carbohydrates it is necessary to consume the servings suggested in this group. The tip or apex of the pyramid represents the smallest group of foods such as fats, oils and sugars, which must eat less.
