Study Notes
Learning Outcomes
- Describe the composition and caloric content of a healthy diet.
- Explain energy balance, Basal Metabolic Rate (BMR), diet-induced thermogenesis (DIT), and Daily Energy Expenditure (DEE).
- Understand Dietary Reference Intakes (DRI) and Total Parenteral Nutrition (TPN).
- Identify essential dietary factors and the consequences of nutritional deficiencies and malnutrition.
A Healthy Diet
- Focuses on fruits, vegetables, whole grains, lean proteins, and low-fat dairy.
- Should limit saturated fats, cholesterol, sodium, and added sugars.
Composition of a Healthy Diet
- Emphasizes a broad variety of foods to meet nutritional needs.
- Encourages physical activity for 30-60 minutes daily to support health.
Principles of Nutrition
- Adequacy: Ensures enough essential nutrients.
- Balance: Includes different food types for nutritional diversity.
- Energy Control: Avoids overeating and undereating.
- Moderation: Consumes nutrients wisely without extremes.
- Variety: Incorporates a wide range of foods for health.
Classification of Nutrients
- Macronutrients (g): Carbohydrates, fats, and proteins provide energy.
- Micronutrients (mg): Vitamins and minerals regulate body functions.
Energy Yielding Nutrients
- Carbohydrates: Provide energy through oxidation; include sugars and starches.
- Proteins: Supply amino acids for bodily functions.
- Lipids: Yield more energy when oxidized; essential for growth and recovery.
Vitamins and Minerals
- Vitamins: Water-soluble (B vitamins, vitamin C) and fat-soluble (A, D, E, K) required to prevent deficiencies.
- Macro-minerals: Include calcium, phosphorus, potassium, and their daily recommended intakes.
- Micro-minerals: Trace essentials like iron and zinc crucial for body function.
Energy Unit: The Calorie
- Energy from food measured in kilocalories (kcal) and kilojoules (kJ).
- Carbohydrates and proteins: 4.0 kcal/g; fats: 9.0 kcal/g; alcohol: 7.0 kcal/g.
Basal Metabolic Rate (BMR)
- Energy used at rest for vital functions, approximately 24 kcal/kg/day.
- Affected by gender, age, and physiological conditions; higher in males and children.
Total Daily Energy Expenditure (TDEE)
- Total calories burned in a day from BMR, physical activity, and diet-induced thermogenesis (DIT).
- Maintains body weight when energy intake equals energy expenditure.
Dietary Reference Intakes (DRI)
- Guidelines for assessing nutrient intake for healthy populations.
- Includes Lower Reference Nutrient Intake (LRNI), Estimated Average Requirement (EAR), Recommended Dietary Allowance (RDA), and Upper Limit (UL).
Total Parenteral Nutrition (TPN)
- Method of feeding intravenously, bypassing the digestive system, providing essential nutrients.
Body Mass Index (BMI)
- BMI calculates body weight relative to height, correlating with health risks.
- Example calculation: Weight (72kg) and height (1.83m) yield a BMI of 21.5 kg/m².
BMI Ranges
- Utilized to evaluate whether an individual is underweight, healthy, overweight, or obese, indicating potential health risks.
