What is Nutrition?
Nutrition is the science of how food affects the body’s health and performance. It involves the intake of nutrients—such as carbohydrates, proteins, fats, vitamins, and minerals—that are essential for growth, energy, and cellular repair. A well-balanced diet, rich in these nutrients, lays the foundation for a healthy lifestyle.
Why is Good Nutrition Important?
Proper nutrition is critical for maintaining overall health and well-being. It helps boost immunity, reduce the risk of chronic diseases (like diabetes, heart disease, and obesity), and supports mental health. Children and adolescents especially need nutritious food for proper growth and development.
Benefits of Healthy Nutrition:
- Increases energy levels
- Enhances mental clarity and focus
- Promotes healthy weight management
- Supports muscle growth and repair
- Strengthens the immune system
Key Nutrients Your Body Needs
1. Carbohydrates
Carbohydrates are the body’s main energy source. Found in fruits, vegetables, grains, and legumes, complex carbs provide lasting energy and are rich in fiber.
2. Proteins
Proteins are crucial for building and repairing tissues. Sources include lean meats, eggs, dairy, legumes, and plant-based proteins like tofu and tempeh.
3. Fats
Healthy fats, such as those found in avocados, nuts, seeds, and olive oil, support brain health and hormone production. Avoid trans fats and limit saturated fats.
4. Vitamins and Minerals
Micronutrients like Vitamin C, D, calcium, and iron are essential for immune function, bone health, and blood production. These are mostly found in fruits, vegetables, dairy, and lean meats.
5. Water
Staying hydrated is a key part of good nutrition. Water supports digestion, nutrient absorption, and temperature regulation.

How to Improve Your Nutrition
Improving your diet doesn’t have to be overwhelming. Start with small, sustainable changes:
- Replace sugary drinks with water or herbal tea
- Choose whole grains over refined grains
- Include at least 5 servings of fruits and vegetables daily
- Reduce processed foods and opt for home-cooked meals
- Read nutrition labels to make informed food choices
