Unit 1515: Comprehensive Nutrition Fundamentals

1. Introduction to Macronutrients and Micronutrients

• Definition of macronutrients and micronutrients
• Importance of nutrients in diet and overall health
• Key differences between macronutrients and micronutrients

2. Macronutrients: Carbohydrates

• Role of carbohydrates in the body
  • Energy production
  • Brain function
• Types of carbohydrates
  • Simple carbohydrates (sugars)
  • 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
  • Tissue building and repair
  • 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
• Functions of fats in the body
  • Energy storage
  • Cell membrane structure
  • Absorption of fat-soluble vitamins
• Sources of healthy fats
  • Olive oil, avocados, nuts, fatty fish
• Impact of fats on heart health
  • Effects of different fats on cholesterol and cardiovascular risk

5. Micronutrients: Vitamins

• Role of vitamins in the body
  • Metabolic processes
  • Immune function
  • Antioxidant properties
• Classification of vitamins
  • Fat-soluble vitamins (A, D, E, K)
  • Water-soluble vitamins (B-complex, C)
• Dietary sources of vitamins
  • Fruits, vegetables, dairy, fortified foods
• Consequences of vitamin deficiencies
  • Common deficiency diseases (e.g., scurvy, rickets)

6. Micronutrients: Minerals

• Importance of minerals for bodily functions
  • Bone health
  • Nerve transmission
  • Enzyme function
• Classification of minerals
  • Macro minerals (calcium, potassium, magnesium)
  • Trace minerals (iron, zinc, selenium)
• Sources of minerals in the diet
  • Dairy, meat, whole grains, vegetables
• Health implications of mineral deficiencies
  • Anemia, osteoporosis, thyroid disorders

• Significance of water as an essential nutrient
• Functions of water in the body
  • Temperature regulation
  • Transport of nutrients and waste
  • Lubrication
• Importance of hydration
• Consequences of dehydration
  • Physical and cognitive effects

8. Nutrient Interactions

• How macronutrients and micronutrients interact
• Absorption and utilization of nutrients
• Impact of nutrient interactions on health
• Importance of a balanced diet for optimal nutrient availability

9. Recommended Daily Intake (RDI) of Nutrients

• Explanation of RDI and its purpose
• RDIs for macronutrients and micronutrients by age group and population
• Strategies to meet nutrient requirements through diet
• Special considerations for vulnerable populations

10. Nutritional Supplements

• Role and purpose of nutritional supplements
