There are three macronutrients (macros) that comprise all of the foods we consume on a daily basis. These three nutrients are proteins, fats, and carbohydrates.
Each macronutrient plays a vital role in the functioning of our bodies. Eating a healthy, well balanced diet includes all of these nutrients. The ratios may differ based upon a number of different factors, including body size and shape, as well as age. The one thing that does not change is that all three are required in order for the body to perform all of it’s functions.
