How protein fat and carbohydrates in the diet provide.

The human body needs proteins, lipids, and carbs for energy and building components. Each macronutrient contributes to the diet:

Structure, function, and regulation: Proteins are necessary for tissue and organ function. They are essential for muscle, tissue, enzyme, hormone, and antibody healing.

Proteins are made of amino acids. The body cannot generate vital amino acids, hence they must be eaten.Sunlight:

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.
