Study Notes
Macronutrients
- Provide energy and support growth and maintenance of body functions
- Three main categories:
-
Carbohydrates:
- Provide 4 kcal/g of energy
- Found in grains, fruits, vegetables, and dairy products
- Main function: energy source for the body
-
Protein:
- Provide 4 kcal/g of energy
- Found in meat, poultry, fish, eggs, dairy products, and legumes
- Main function: build and repair body tissues
-
Fats:
- Provide 9 kcal/g of energy
- Found in oils, nuts, seeds, avocados, and fatty fish
- Main function: energy storage, hormone regulation, and brain function
-
Carbohydrates:
Micronutrients
- Essential for maintaining optimal health, but required in smaller amounts
- Two main categories:
-
Vitamins:
- 13 vitamins recognized by the human body
- Fat-soluble (A, D, E, K) and water-soluble (B, C)
- Important for energy metabolism, immune function, and growth
-
Minerals:
- 15 minerals recognized by the human body
- Essential for maintaining fluid balance, nerve function, and bone health
- Examples: calcium, iron, potassium, zinc
-
Vitamins:
Nutrient Deficiencies
- Occur when the body does not receive sufficient amounts of essential nutrients
- Can lead to various health problems, including:
- Fatigue and weakness
- Impaired immune function
- Poor wound healing
- Increased risk of chronic diseases
- Common deficiencies:
- Iron deficiency anemia
- Vitamin D deficiency
- Calcium deficiency
- Omega-3 fatty acid deficiency
Diet Planning
- Involves creating a personalized eating plan to meet nutritional needs
- Key considerations:
- Caloric needs: based on age, sex, weight, and activity level
- Macronutrient balance: balance of carbohydrates, protein, and fats
- Micronutrient intake: ensuring adequate intake of vitamins and minerals
- Food variety: including a wide range of whole, unprocessed foods
- Effective diet planning strategies:
- Meal planning: planning and preparing meals in advance
- Portion control: controlling serving sizes to maintain appropriate caloric intake
- Mindful eating: paying attention to hunger and fullness cues to avoid overeating
