For what reasons does the human body requires nutrition.  (Part-1)

The body needs nutrients for health, growth, development, and physiological activities. Here are the main reasons humans need nutrition:

Carbs: The body's main energy source. Cells run on glucose, which comes from carbohydrate breakdown.

Proteins develop and repair muscles, organs, skin, and enzymes. Proteins are essential to cell structure and function.

Vitamins and minerals regulate biological reactions as cofactors and coenzymes. They are necessary for metabolism, immunity, and nerve transmission.

Fats: Concentrated energy storage and insulation. Fat in adipose tissue stores surplus energy for peak energy needs.

Fiber promotes regular bowel motions, prevents constipation, and supports the gut microbiota.

Calcium, Vitamin D, and Phosphorus: Essential for strength and bone health. Bone structure requires calcium and phosphorus, and vitamin D improves calcium absorption.

Fats: Produce hormones, especially steroids. Hormones control metabolism, growth, and other processes.
