• Portion sizes and food groups
• Recommendations to prevent chronic diseases
• Meal planning basics

3. Food Groups and Nutrient Sources

• Classification of food groups
• Nutrient composition of each group
• Essential nutrient sources: plant vs animal
• Impact of food choices on nutrient intake

4. Digestion and Absorption of Nutrients

• Anatomy and physiology of the digestive system
• Process of digestion: mechanical and chemical
• Role of enzymes in nutrient breakdown
• Absorption mechanisms for macronutrients and micronutrients
• Factors affecting nutrient bioavailability and gut health

5. Energy Balance and Metabolism

• Concepts of energy intake and expenditure
• Basal metabolic rate (BMR) and factors influencing it
• Thermic effect of food (TEF)
• Energy storage and utilization
• Metabolic pathways for macronutrients

6. Nutritional Requirements Across the Lifespan

• Nutritional needs in infancy, childhood, adolescence
• Adult nutritional requirements
• Nutrition during pregnancy and lactation
• Nutritional considerations for older adults
• Impact of growth, development, and aging on nutrient needs

7. Macronutrients

7.1 Carbohydrates

• Types: simple, complex, fiber
