What is Nutrition?

Nutrition involves the process by which living organisms receive and utilize the nutrients necessary for growth, maintenance, and repair of tissues. Nutrients are substances obtained from food and fluids that are essential for health. These include macronutrients—carbohydrates, proteins, and fats—and micronutrients—vitamins and minerals.

Macronutrients: The Energy Providers

1. Carbohydrates: - Function: Primary source of energy. - Sources: Found in fruits, vegetables, grains, and legumes. - Importance: Supports brain function and physical activity. 2. Proteins: - Function: Essential for building and repairing tissues. - Sources: Meat, fish, dairy, legumes, and nuts. - Importance: Composed of amino acids, crucial for enzymes and hormones.

3. Fats: - Function: Energy storage, insulation, and cell structure support. - Sources: Oils, butter, avocados, nuts, and fatty fish. - Importance: Helps in the absorption of fat-soluble vitamins.

Micronutrients: The Body’s Helpers

1. Vitamins: - Required in small amounts for various bodily functions, ranging from vision to immune health. - Examples include Vitamin A, C, D, E, and the B-complex family.

2. Minerals: - Support processes such as bone health, oxygen transport, and nerve function. - Key minerals include calcium, iron, magnesium, and potassium.

The Role of Water
