The human body needs proteins, lipids, and carbs for energy and building components. Each macronutrient contributes to the diet:
Food Sources: Protein-rich foods include meat, poultry, fish, dairy, eggs, legumes, nuts, and seeds.
Function: Fats provide concentrated energy and help absorb fat-soluble vitamins A, D, E, and K. They help in cell structure, hormone production, and insulation.
Function: The body gets energy from carbohydrates. They are converted to glucose, which is used for energy or stored as glycogen in the liver and muscles.
Food Sources: Whole grains, fruits, vegetables, legumes, and starchy vegetables (potatoes, sweet potatoes) are carbohydrate-rich.
Dietary macronutrient balance is essential for health. The optimal macronutrient distribution depends on age, sex, physical activity, and health goals.
