Core Principles of Contemporary Nutrition:
1. Understanding Macronutrients:
Macronutrients-carbohydrates, proteins, and fats-are the building blocks of nutrition. Each serves distinct roles in the body:
- Carbohydrates: Primary energy source; found in grains, fruits, and vegetables.
- Proteins: Essential for tissue repair and growth; found in meats, legumes, and dairy.
- Fats: Provide long-term energy storage and support cell structure; sourced from oils, nuts, and fatty fish.
Balancing these macronutrients according to your activity level and health goals is crucial.
2. Micronutrient Essentials:
Micronutrients, including vitamins and minerals, are critical for physiological processes like immunity and bone health. For example:
- Vitamin C: Supports immune function and skin health.
- Calcium: Essential for bone density and muscle function.
Incorporating a variety of foods ensures adequate micronutrient intake.
3. The Role of Fiber:
Fiber, a non-digestible carbohydrate, is vital for digestive health. High-fiber diets are linked to reduced risks of heart disease, obesity, and type 2 diabetes.
Sources of dietary fiber:
- Fruits and vegetables

- Legumes
