Growth and Development. -
Provision of Energy.
Repair and maintenance of the body's cells.
Carbohydrates
Carbohydrates give you energy, calcium and B vitamins. These could be servings of pasta, rice, oats, potatoes and sweet potatoes or noodles, yam, couscous, bread, barley and rye. Breakfast cereals are also a carbohydrate and many contain extra iron too.
Protein
Think of proteins as building blocks for the body – they help it grow and repair itself. Protein is found in meat, fish and eggs, while nuts, beans, lentils, peas, dahl, Quorn and soya are great vegetable proteins. These foods also provide us with iron and other vitamins and minerals.
Dairy products
Packed with calcium, protein and vitamins such as vitamins A, D and B12, dairy products keep our bones and teeth healthy. Our bodies easily absorb the calcium from these foods, such as milk, yoghurt, fromage frais and cheese.
Fruit and vegetables
Fruit and veg – fresh, frozen, tinned, dried and juices – are brilliant for our diets. They’re full of health-giving vitamins, antioxidants and fibre – that keep us feeling full and our digestive systems healthy – plus they’re low in calories. By eating a wide variety of fruit and veg, you’ll be getting a range of the important nutrients they contain.
Fats and sugars
It’s important not to have too many foods from this group as they give us a lot of energy from calories but not much nutrition. Try to keep foods such as butter, margarine, cooking oils and salad dressings to a minimum and save chocolate, crisps, sugary soft drinks, sweets, jam, cream, cakes, pudding, biscuits and pastries for the occasional treat.
