Food nutrition is the study of how food provides the essential nutrients the body needs for growth, energy, and maintenance. It includes macronutrients, micronutrients, and water.
1. Macronutrients
Carbohydrates: The body’s main energy source, found in grains, fruits, and vegetables.
Proteins: Important for building and repairing tissues; found in meat, legumes, dairy, and nuts.
Fats: Provide long-term energy, support cell function, and help absorb vitamins. Healthy fats come from sources like avocados and nuts.
2. Micronutrients
Vitamins: Regulate body processes (e.g., Vitamin A for vision, B-vitamins for energy).
Minerals: Support bone health, oxygen transport, and fluid balance (e.g., calcium, iron, potassium).
3. Water
Essential for hydration, digestion, temperature regulation, and waste removal.
