Study Notes
Understanding Nutrients
- Nutrients are essential for health and energy, functioning similarly to fuel for a car.
- Two main types of nutrients: energy-providing and body-building.
- A diverse diet is crucial to obtain the necessary nutrients and avoid deficiencies.
- Nutrient deficiencies are rare in industrialized countries but can lead to severe health issues.
- Over 40 identified nutrients grouped into six main classes: proteins, carbohydrates, fats, vitamins, minerals, and water.
Proteins
- Proteins support healing, growth, and tissue repair.
- Built from amino acids; complete proteins (e.g., meat, fish, eggs, soybeans) provide all essential amino acids.
- Many plant foods lack one or more amino acids; vegetarians may need to combine foods (e.g., beans and rice) to meet protein needs.
Fats
- Fats help induce a feeling of fullness; not all fats are created equal.
- Saturated fats (found in butter, cheese, meats) are solid at room temperature and can raise LDL cholesterol, increasing heart disease risk.
- Unsaturated fats (from plants, like olive oil and nuts) remain liquid and can lower heart disease risk.
- Cholesterol has two types: HDL (protects against heart disease) and LDL (contributes to heart disease).
Vitamins and Minerals
- Vitamins aid against disease, while minerals regulate bodily functions.
- Two categories of vitamins: water-soluble (e.g., Vitamin C, B; require daily intake) and fat-soluble (e.g., Vitamins A, D; stored in fat).
- A varied diet helps ensure adequate intake of vitamins and minerals; supplements can aid but shouldn’t replace healthy food.
Water
- Vital for all body functions; a person can only survive about a week without it.
- Water transports nutrients, aids digestion, removes waste, and regulates temperature.
- Recommended water intake: about nine cups daily for teen girls and 13 cups for teen boys.
- Foods like fruits and vegetables provide additional hydration; caffeine-containing beverages should be consumed in moderation.
Carbohydrates
- Primary energy source, made of sugar molecules; 45-65% of daily energy needs should come from carbohydrates.
- Two types: simple (natural sources like fruit and milk) and complex (starches from potatoes, seeds, and whole grains).
- Complex carbohydrates must be digested before use; fiber, a form of complex carbohydrate, aids digestion but is not a direct energy source.
- High-fiber foods can reduce risks of heart disease and certain cancers.
Fats (continued)
- Some fats are necessary for proper bodily functions, including cell membrane maintenance and the absorption of certain vitamins.
