Information on Macronutrients for Body
Carbohydrates, lipids or fats and proteins are the three macronutrients which provide energy and other micronutrients to the body to perform vital functions. Carbohydrates and proteins provide 4 calories each per gram and lipids provide almost double that is 9 calories per gram.
Carbohydrate is considered as a preferred fuel for energy by the major organs of the body like heart, brain, and kidneys. Carbohydrates can be divided in to 2 groups that are simple carbohydrates and complex carbohydrates. Simple carbohydrates are metabolized and digested in the body quickly which cause blood sugar spike, however they are also famous to give instant energy in emergency situations like hypoglycemia. Complex acarbohydrates on the other hand get digested slowly in the body by releasing small amounts of glucose at a time. Common examples include whole cereals, grains, pulses, beans, and vegetables.
Proteins are required to build muscles in the body and are known as the building blocks of the body. They are also required for other body functions like synthesis of hormones, maintaining healthy bones, nails and hair, and connective tissue.
Fats or lipids are complex molecules composed of glycerol and fatty acids. Fats are often seen as culprits for weight gain and obesity, but some amount of fat is required for various body functions in the body. Excess fat is however stored in the body when not utilized.
