- Complex carbohydrates (starches and fiber)
- Dietary sources of carbohydrates
- Fruits, vegetables, grains, legumes
- Impact of carbohydrates on health
- Blood sugar regulation
- Fiber and digestive health
- Risks of excessive sugar intake
3. Macronutrients: Proteins
- Importance of proteins for bodily functions

- Enzyme and hormone production
- Sources of protein
- Animal-based (meat, dairy, eggs)
- Plant-based (legumes, nuts, seeds)
- Complete vs. incomplete proteins
- Definition and examples
- Role of proteins in muscle building and repair
4. Macronutrients: Fats
- Types of fats
- Saturated fats
- Unsaturated fats (monounsaturated and polyunsaturated)
- Trans fats
