Nutritional needs: fats, proteins and carbohydrates

Every day, we need food correctly in order to enjoy good health. This is so, because our body has a series of nutritional needs that have to do with fats or lipids , proteins Y carbohydrates that we need to consume daily.


In this aspect, foods contain organic elements (such as lipids or fats, carbohydrates and carbohydrates, vitamins, proteins and mineral salts) and water and even fiber that are certainly essential for the body.

For this main reason, our daily diet should include up to 50-55% of carbohydrates or carbohydrates, 25-30% of fats and between 12 and 15% of proteins.

Nutritional needs of our body

  • Carbohydrates and carbohydrates
    As we have mentioned, our daily diet should include up to 50-55% of carbohydrates and carbohydrates, which are the most important nutrient for our body.
    This is because carbohydrates are absorbed in the form of glucose, and our cells depend on it to function properly.
    As far as carbohydrates are concerned, they are ingested from polysaccharides, especially vegetable starch.
  • Fats or lipids
    They have to form between 25 and 30% of our daily diet, and they tend to provide a very caloric energy, although fundamental, since they intervene in the absorption of those vitamins called liposoluble.
    In this case, there are two types of fats, which are divided into vegetable fats (which we must take, but in moderation, since through them we metabolize fat-soluble vitamins, and accumulate fats), and animal fats (which are the first that, for example, we must eliminate from the diet when we want to control the high cholesterol ).
  • Proteins
    They are necessary and essential to form and regenerate the different tissues of the body. Of course, when we do the digestion, these are transformed into amino acids, which, some of them, are called as essential amino acids , since our body can not produce them, and are responsible for the energy and composition of hormones, antibodies and enzymes.
