Study Notes
Nutrition - Chapter 1
- Body's complex chemical reactions are called metabolism
- Energy is needed for all metabolic reactions, and the body must remain healthy to be efficient
- Intake of nutrients in food is crucial for all living things
- There are five main groups of nutrients: protein, fat, carbohydrate, vitamins, and minerals
- Macronutrients (protein, fat, carbohydrate) are needed in larger amounts, and include minerals like sodium, calcium, potassium, phosphorus, and magnesium.
- Micronutrients (vitamins, essential fatty acids, and trace minerals like iron, zinc, copper, iodine, selenium, chromium, and cobalt) are needed in smaller amounts.
- Water is also considered a vital nutrient
- Dietary fiber (NSP) is important to the body, but not strictly a nutrient
- Dietary reference values (DRVs) are used to establish people's requirements for energy and nutrients.
- DRVs are not meant to be targets for individuals, they are general values established for different population groups with changing needs based on factors like age and health condition.
- Estimated average requirement (EAR) and reference nutrient intake (RNI) are two important values, and can be compared to the RDA (recommended dietary allowances) values determined in the Caribbean
- People with illnesses, malnutrition, or medical conditions may have different needs for certain nutrients
Protein
- Our bodies are composed of millions of cells that are constantly being replaced and repaired.
- New cells are added as the body grows.
- Each cell comprises protoplasm, containing protein among other substances
- Proteins have many versatile roles depending on their nature and cell type.
- Example functions: providing structural support, involved in bodily movement, & defending against germs
- Protein is primarily important for cell growth and body building
