Role in Human Nutrition

Macronutrients are critical for human nutrition as they provide energy, build and maintain body structures, and support various biological functions.
The three primary macronutrients are carbohydrates, proteins, and fats.
Carbohydrates are the main source of energy for the body.
Proteins offer essential amino acids necessary for the growth, repair, and maintenance of body tissues.
Fats supply energy, help protect organs and form cell membranes, and facilitate the absorption of fat-soluble vitamins A, D, E, and K.
A balanced intake of these macronutrients is vital for optimal health and wellbeing.
