All food is composed of a varied combination of three macronutrients: proteins, carbohydrates, and fats. A macronutrient is a nutrient that is needed in relatively large quantities for normal growth and development of an individual. Macronutrients are the body's source for calories - energy that fuels the body. Each macronutrient has a designated number of calories per gram: proteins - 4 calories/gram, carbohydrates - 4 calories/gram, fats - 9 calories/gram.

Over the next 3 weeks we will take a more in-depth look into each macronutrient; what it does and its importance to the function of the human body. So stay tuned for the upcoming macronutrient blogs: protein 101, carbohydrates 101, & fats 101.
