Carbohydrates

Carbohydrates are macronutrients that provide energy for the body. Their primary functions include providing fuel for the central nervous system, enabling fat metabolism, and supporting physical activity.

Carbohydrates are classified as simple or complex. Simple carbohydrates include sugars like glucose and fructose, while complex carbohydrates include starches found in grains, legumes, and vegetables.

The recommended daily intake of carbohydrates is around 45-65% of total daily calories. However, individual factors such as age, sex, activity level, and metabolic health can influence the specific carbohydrate needs of an individual.
