| Balanced diet | Diet containing the correct proportions of the 6 nutrients |
| Glucose | A sweet tasting, monosaccharide |
| Six nutrients | Fats, vitamins, minerals, water, carbohydrate, proteins |
| proteins | This nutrient contains the elements carbon, hydrogen, oxygen and nitrogen |
| Carbohydrates | Function: provides the body with energy |
| Fructose | This is the sugar found in fruit |
| Lactose | This is the sugar found in milk |
| Sucrose | This is table sugar |
| Tooth decay | This is a health problem associated with too much sugar in your diet |
| Starch | This is a large, insoluble carbohydrate found in plants |
| Glycogen | This is a large sugar molecule found in animals |
| Cellulose | This is an indigestible carbohydrate that humans cant digest (forms fiber) |
| Fibre/roughage/ | This prevents constipation |
| Monosaccharide’s | Single sugar units |
| Disaccharides | Two sugar units |
| polysaccharides | Many sugar units |
| Lipids (fats and oils) | Used for energy and protection of delicate organs |
| Lipids | Contain the elements carbon, hydrogen and oxygen but less oxygen than carbohydrates |
| carbohydrates | Contain the elements carbon, hydrogen and oxygen but more oxygen than lipids |
| Animal fats | Type of fat that is solid at room temperature |
| Vegetable fat | Type of fat that is liquid at room temperature |
| Lipids | Made up from 3 fatty acids and 1 glycerol molecule |
| Proteins | Made up from chains of amino acids joined together |
| Cholesterol | Taken into the body in dairy products, made in the liver, forms part of cells, causes heart disease |
| Meat, fish, eggs, cheese, beans | Foods that are good sources of proteins |
| Growth and repair | Function of proteins |
| Fish liver oils, carrots, butter | A good source of vitamin A |
| Fresh fruit and veg | A good source of vitamin C |
| Sunlight, fish liver oils | A good source of vitamin D |
| Dairy and veg | A good source of the mineral Calcium |
| Red Meat and spinach | A good source of the mineral iron |
| Healthy eyes | The function of vitamin A |
| The function of vitamin C | Sticks together cells lining surfaces such as the mouth |
| The function of vitamin D | Healthy bones and teeth |
| The function of calcium | Making bones and teeth |
| Making haemoglobin so prevents anaemia | The function of iron |
| Iodine goes from red/brown to blue/black | Test for starch |
| Benedicts solution warmed goes from blue to red(or orange or green) | Test for sugar but not for sucrose |
| Biuret test: goes blue to purple | Test for proteins |
