The three primary macronutrients–protein, fat, and carbohydrates–all perform essential roles in the human body. Macronutrients are the main components of our diet. Our bodies require others nutrients as well, such as vitamins and minerals. However, these are needed in much smaller quantities, and thus are referred to as micronutrients. All three macronutrients are needed in the diet, as each perform vital functions in the body.
1.Protein
Protein should consist of about 10 to 35 percent of your diet. Protein builds, maintains and repairs body tissue. It is especially important to physically active individuals. Among its many functions, protein also aids in the immune process
2. Fat
The misconception about fat is that it is always bad for you. In fact, fat is essential for maintaining a healthy body. Your diet should consist of about 20 percent fat. The trick is to eat more of the good fats such as nuts, avocados, and olive oil and less of the bad fats.
Fat has many roles in the human body including promoting growth and development, as well as maintaining cell membranes. Additionally, Vitamins A, D, E, and K are fat soluble vitamins, meaning they need fat in order to be absorbed into the body.
3.Carbohydrates
Carbohydrates are the main energy source of the body. For this reason, your diet should consist of at least 45 to 65 percent carbohydrates. Carbohydrates are found in many foods. However, you should stay away from sweet foods with excess sugar. Instead, opt for healthier options like fruits, vegetables, beans and nuts, as well as whole grains.
