Study Notes
Nutrition - Energy and Nutrients
- Body needs energy for metabolic reactions; this is achieved through nutrients, like all living things.
- Nutrients are categorized into five main groups: protein, fat, carbohydrate, vitamins, and minerals.
- Macronutrients are needed in large amounts, like protein, fat, carbohydrate, and some minerals (sodium, calcium, potassium, phosphorus, and magnesium).
- Micronutrients are needed in smaller amounts, like vitamins, essential fatty acids, and trace elements (iron, zinc, copper, iodine, selenium, chromium, and cobalt). Water is also vital.
- Dietary Fibre (non-starch polysaccharide) is not strictly a nutrient but still important.
Dietary Reference Values (DRVs)
- The UK Department of Health provides charts for energy and nutrient requirements.
- These charts summarize dietary reference values (DRVs).
- Averages are used, not specific targets for individuals.
- Needs vary with age and life stage (e.g., a 5-year-old boy versus a pregnant woman).
- People with illnesses, malnutrition, or specific medical conditions might have individual needs; Average figures may not fit well for these people
Protein
- Proteins are crucial as building blocks and for growth materials.
- Cells are constantly replaced and repaired in the body, with new cells being added as the body grows.
- Protein are a major component of protoplasm, the substance within each cell.
- Proteins have many functions; some are involved in structural support, muscle movement, or disease resistance.
- Protein is crucial in cell composition.
- Different proteins have various roles in cells dependent upon their type and location.
