Study Notes
Nutrition
- Body cells are constantly damaged and repaired, requiring a continuous supply of nutrients for chemical reactions (metabolism)
- Energy is needed for bodily functions, and intake of nutrients from food is key for healthy functioning
- Two crucial dietary reference values (DRVs) are important: estimated average requirement (EAR) and reference nutrient intake (RNI)
- The recommended daily intake (RNI) provides the amount of a nutrient needed by 97% of a population group.
- The UK uses the Reference Nutrient Intakes (RNIs) while some Caribbean regions utilize Recommended Dietary Allowances (RDAs).
- Five main nutrient groups exist: protein, fat, carbohydrates, vitamins, and minerals.
- Macronutrients (protein, fat, carbohydrates) are needed in large amounts, while micronutrients (vitamins and minerals) are needed in smaller amounts.
- Water is essential for life and can be classified as a nutrient.
- Dietary fiber (non-starch polysaccharide) is also important for the body though not a strictly defined nutrient.
- Dietary needs vary depending on factors such as age, sex, and health status. Specific figures in DRVs are averages and not strict targets for individuals
Protein
- Proteins form the building blocks of cells
- Proteins, a key component of protoplasm, are crucial for cell growth, repair, and maintenance.
- Proteins perform many varied functions in the body, including structural support and various bodily movements.
- Some proteins involved in defending against germs
- Protein helps build bones and teeth
- Protein in muscles enables contraction.
