The three Macronutrients that are the major nutrients one’s body needs to survive. They are protein, carbohydrate and dietary fats. One requires to consume each of the 3 in fairly large quantities to facilitate optimal health.

  1. Protein.  Protein functions as one’s body’s building blocks. It’s in charge of building, maintaining & repairing all a person’s body’s cells. They are created from the chains of 22 amino acids, 8 of which are essential (as they are not produced by one’s body) while 14 are non-essential (as they could be produced by a person’s body). There is an unlimited number of protein kinds as they could be manufactured from any number & combination of the twenty-two amino acids. Then again, protein could be broken down into 2 major types: complete (holds all 8 essential amino acids) & incomplete (doesn’t contain all 8 essential amino acids).

Aside from playing a major role in the production and preservation of healthy cells, they have other essential roles in one’s body. Protein assists in the synthesis of enzymes, antibodies and hormones, helps clot blood and controls several critical processes in one’s body.

Carbohydrate. This macronutrient is a person’s body’s initial source of energy. Carbohydrates or carbs are made from oxygen, hydrogen and carbon. They could be either complex or simple with complex carbs holding 3 or more sugars while simple carbs holding 1 or 2 sugars.

Besides being a terrific energy source, carbohydrates are also a superb source of phytonutrients (protects one’s body from free radical injury) and vitamins. While the majority of this macronutrient supplies one’s body with energy, fiber (or cellulose) is the exclusion from the rule. Fiber is a complex carb that can not be digested & instead of presenting energy, it keeps the glucose levels in the blood under control, promotes regular bowel movement & protects one from various diseases.

  1. Dietary fats. These Macronutrients are produced from a mixture of hydrogen and carbon. Dietary fats can be broken down into 4 major kinds: saturated fats (all carbon molecules are attached to hydrogen molecules), monounsaturated fats (where carbon molecules are attached to the hydrogen molecules at all but 1 point), polyunsaturated fats (carbon molecules are not attached to hydrogen molecules at 2 or more points) & trans fat (initially unsaturated fats that contain a carbon molecule added to them either naturally or artificially).


With the exclusion of man-made trans fat, each dietary fat is advantageous to one’s health and have several roles in his body. Monounsaturated fats keep one’s blood glucose levels under management while protecting him from cancer. Polyunsaturated fat is essential for brain health & also keeps bones strong, good vision and healthy skin. Saturated fats support one’s vital organs, keep his immunologic system healthy & strengthen one’s cell membranes and bones.
