WHAT IS NUTRIENTS?
Substances are usable by the body that make life possible and found in foods unevenly distributed: carbohydrates, fats, proteins, vitamins and minerals. Water and fiber are not fed, but they play an important role for the proper functioning of our body.
Nutrients have the following functions:
- Get the energy needed to perform vital functions (heart pumping, breathing, maintaining body temperature …) and development activity in general.
- Carbohydrates: simple (sugars) and complex (starch)
- Fats and lipids
- Build and sustain organs, tissues, and our defense system against external agents and infections
- Protein: complete (animal) and incomplete (plant)
REGULAR all processes taking place in our body so that all flows in perfect harmony
- Vitamins (water soluble B-group and C-and lipid-A, D, E, K) and minerals
Nutrients are not uniformly distributed in food. In each of them, therefore, predominantly one or the other nutrient. This has been classified into different groups according to their affinity nutrient or principal role in our body the nutrients in each food predominant.
Foods in the same group are interchangeable, provided in adequate amounts, because they share similar nutritional properties. This allows us to vary widely diet without changing significantly the nutritional composition of food daily. We must not forget that in some groups there are differences depending on the amount of fat and sugar (or full-fat milk, fat or lean meats, yogurt with no sugar or sugar …), resulting in greater or lesser number of calories.
BUT WHAT IS A SERVING?
The quantity or type of food rations and to consume depends on the caloric needs of each individual. As an example, follows normocaloric diet of about 2,200 kilocalories per day, valid for an adult weighing about 70 kilos carried out moderate physical activity (sedentary job but you exercise-walking, for an hour every day .)
