What is Nutrition?

Nutrition is the science of how our body uses food to function, grow, and stay healthy. Every bite we eat provides energy and nutrients that support our body’s systems—from fueling our brain to strengthening our muscles and keeping our immunity strong.

Why is Nutrition Important?

Good nutrition is the foundation of health. It:

• Provides energy for daily activities.
• Supports growth and repair of cells and tissues.
• Strengthens the immune system to fight diseases.
• Helps maintain a healthy weight.
• Lowers the risk of chronic illnesses like diabetes, heart disease, and obesity.

The Building Blocks of Nutrition

1. Carbohydrates (Energy Providers)
   • Main source of energy.
   • Found in: whole grains, fruits, vegetables, legumes.
   • Choose complex carbs (brown rice, oats) over refined (white bread, sugary snacks).
2. Proteins (Body Builders)
   • Essential for muscle repair, growth, and immune support.
   • Found in: lean meats, fish, eggs, beans, lentils, nuts, dairy.
3. Fats (Energy & Hormone Support)
   • Provide long-lasting energy and help absorb vitamins.
   • Healthy fats: avocado, olive oil, nuts, seeds, fatty fish.
   • Limit unhealthy fats: fried foods, processed snacks, trans fats.
4. Vitamins & Minerals (Micronutrient Heroes)
   • Support vital functions like immunity, bone health, and metabolism.
   • Found in colorful fruits, vegetables, nuts, and seeds.
   • Examples: Vitamin C (oranges) for immunity, Calcium (dairy, leafy greens) for bones.
5. Water (The Forgotten Nutrient)
   • Vital for digestion, circulation, and temperature regulation.
   • Aim for 6–8 glasses a day, more if active.
