Introduction to the nutrients
Aims
- To show how nutrients are classified and discuss their main roles
- To describe how nutrients may interact to fulfil similar roles
Classification of nutrients
- Macronutrients are required in relatively large amounts, usually expressed in terms of grams per day.
- Micronutrients are required in small amounts, usually expressed in terms of milligrams or micrograms per day.
Macronutrients
- Carbohydrates and fats are the major providers of energy, although proteins can also be used to provide energy.
- They all have a structural role in the body, the most important in this respect being proteins.
- All contain carbon, hydrogen and oxygen. In addition, all proteins contain nitrogen, while some amino acids (cysteine and methionine) that are found in proteins contain sulphur.
