| Function of Proteins | For growth and repair of cells. During digestion proteins are broken down into amino acids. |
| Proteins in the body | there are 20 naturally occurring amino acids in the body. these can be joined together to form proteins. They make up: muscles, hormones,enzymes, nails, antibodies and haemoglobin The body can make 11 of these amino acids and the rest are required from food. |
| Sources of proteins | mainly found in animal and soya (high biological value) Other plant sources (low biological value) ANIMAL INCLUDES DAIRY PRODUCTS |

| Ethical considerations of meat alternatives | They can be produced organically They are made in controlled environments keeping pollution to a minimum They are cheaper and quicker to produce than actual meat they can be stored easily because they're dry products |
| FATS | ENERGY: stored in the body until it's needed when energy is needed, fat already in the body is used up PROTECTION: fats surrounds vital organs and it is under our skin and helps us to keep warm TASTE: used to add flavour and colour to foods It makes us feel full because it is slow to digest VITAMINS: provides the body with fat soluble vitamins: ADEK |

| Functions of Carbohydrates | Provide the body with energy and aid growth and repair. |
| Types of carbohydrates | Starch: polysaccharides (BREAD) Sugar: monosaccharides (sucrose and fructose) also disaccharides (lactose and sucrose) NSP: Oats, bananas, fibrous products |
| Conversion of carbohydrates into energy | Sugars are absorbed quickly in the body. they provide instant energy. Starches are converted into energy more slowly. they must first be broken down into sugars during digestion. |
