 Nutrition: Macronutrients

Macronutrients are classified as the nutrients that we need in the largest amounts. They include Fats, Proteins and Carbohydrates and are essential for many processes in the body. The reason why we need such large quantities of the nutrients compared to the micronutrients is because they provide the energy the body needs. While the amount of each micronutrient each person needs remains relatively stable, the type and quantity of each of the macronutrients required can vary greatly and on a day to day basis.

Carbohydrates form our main energy source as it is most readily used by the body, particularly the muscles and the brain. It therefore is the macronutrient that should vary most in quantity, as it is the best fuel for exercise. Once you have established the best protein and fat intake for you, it is best to try and keep these relatively stable, and vary your carbohydrate intake according to you daily energy needs.

Fibre is also an important part of the diet for good health. Fibre consists of carbohydrates that cannot be digested, and therefore are not strictly nutrients as they body does not absorb them, but they are crucial for the digestion of the other nutrients.
