Nutrients are divided into two: Macronutrients and Micronutrients.


Within this group are:

  • Carbohydrates, which is the main source of quick energy for the body. They are divided into simple and complex carbohydrates, the difference of which is based on the rate of absorption.

Simple carbohydrates release glucose more easily and stimulate the production of the hormone insulin to a greater extent, which increases appetite and induces more body fat to be created. For this reason, it is convenient to obtain glucose from complexes, which are found in pasta, cereals, flour, rice, among others.

  • Proteins : vitamins are nutrients that regulate an infinity of vital functions for the human body. Among its main functions, it is responsible for transporting substances through the bloodstream, in addition to particularly in the formation of new enzymes, proteins and cells. Its structural function is one of the most important for muscles and organs in general.

In micronutrients are vitamins and minerals.

  • Vitamins perform many functions within the human body, especially by participating in many chemical reactions, serving as a catalyst. Among the most important are vitamin E, A, C, D, K, and the B complex.
  • Finally, minerals also act as catalysts, being of importance in the transmission of nerve impulses and in the regulation of muscle contractions. They also participate in digestion and metabolism. The most important are copper, magnesium, zinc, iron, calcium, etc.
