Functions of Each Macronutrient in our diet

Macronutrients are essential for the day to day operation of your bodies. Macronutrients include fats, carbohydrates, and proteins which are responsible for various functions in the body.

It is important to understand the purpose of each macronutrient by knowing what core functions they play in the body. Below is a breakdown of how each works.

Carbohydrates

Carbohydrates are mainly energy giving foods. This is because they are digested to produce glucose which is the main source of energy for the body. The glucose is also referred to as sugars. It is the energy source for both the central nervous system and muscles. Excess glucose is converted into triglycerides and stored in the cells until the body needs energy when they are converted back. The name carbohydrates come about due to their chemical composition. They contain carbon, hydrogen, and oxygen. 

Sources of carbohydrates include grains, starchy vegetables, whole fruit and dairy among others.

Proteins

The main function of proteins is bodybuilding and acts as a repair agent. However, in particular, proteins are an important component in every cell in the body. Your hair and nails are majorly made of proteins. It is also used in making enzymes and hormones among other body chemicals. Lastly, proteins are considered an important building block for muscles, cartilage, bones, skin, and blood.

Food sources of proteins include lean meats, poultry, fish, beans, soy products, and nuts.

Fats

Fats can also be considered as a source of energy for the body though it should be consumed in moderate amounts. When the body lacks carbohydrates as a source of energy, then the body reaches into the fat reserves and begins breaking down fat for energy. It is consumed in moderation because when carbohydrates are available, the fat is stored away. 

Sources of fat include fatty fish, avocado, butter, cheese, nuts, seeds and vegetable oils.
