Study Notes
Energy and Nutrient Sources
- Swimming for 20 minutes does not justify consuming a large candy bar or ice cream cone, as it does not provide enough calorie expenditure to offset that intake.
- Carbohydrates should provide the majority of energy requirements for both adults and children.
- Starch, lactose, and sucrose must be fully digested to be utilized for energy.
- Insufficient energy from fats and carbohydrates forces the body to use protein as an energy source.
Importance of Dietary Components
- Cellulose is not a traditional nutrient but plays a significant role in maintaining a healthy diet.
- Infants have high energy requirements due to rapid growth, necessitating adequate calorie intake.
- Fats are energy-dense, offering more than double the calories per gram compared to proteins or carbohydrates.
- Increased fruit consumption doesn't effectively eliminate sugar from the diet.
Fat and Protein Considerations
- Unsaturated fats are not primarily sourced from animal foods; they are mostly found in plant-based sources.
- Proteins are typically reserved for energy use when there is a deficiency of carbohydrates and fats.
Nutrient Classes and Energy
- Vitamins do not supply direct energy while all other nutrient classes (carbohydrates, fats, and proteins) do.
- Fats are identified as the most concentrated energy source in the diet.
- Carbohydrates encompass sugars, starches, and certain fibers, integral for energy.
- Complete digestion of carbohydrates results in the formation of simple sugars.
Nutritional Calculations and Factors
- If 50% of a diet consisting of 1,800 calories comes from carbohydrates, it equates to 225 grams of carbohydrates.
- Key factors influencing a child's caloric needs include their rate of growth and physical activity levels.
Dietary Compositions
- Foods high in dietary fat include combinations such as butter, milk, and corn oil.
- Fats from beef, lamb, and butter are notably rich in saturated fats rather than polyunsaturated fatty acids (PUFAs).
Energy Requirements and Digestion
- The thermic energy of food encompasses the energy required for digestion, absorption, and metabolism of that food - all actions are necessary for energy processing.
Cholesterol Sources
- Major dietary sources that contribute to cholesterol levels include poultry, cheese, and milk.
