The food pyramid is a guide for planning a healthy diet. I f you eat the recommended portions of each food group every day, you will get all the nutrients you need and you will have enough calories to keep you healthy. It is also important to vary the food you eat as much as possible within each food group, because different foods contain different kinds of nutrients. Carbohydrates make up the biggest part of the pyramid, Nutritionists recommend that 60-65% of the food we eat everyday should be made up of carbohydrates. They provide vitamin B, minerals and fibre. Foods in this group include head, cereal, and pasta. Nutritionists recommend we cat 6-7 portions of these foods per day Fruit and vegetables also contain carbohydrates and are a good source of vitamins, minerals and file. We should eat between 3-5 portions of fruit and vegetables each day. Protein is important but should be eaten in moderation We can find it in dairy products such as milk, cheese yoghurt. These foods also contain calcium and vitamins. We should choose dairy products with lower levels of fat and only cat i -2 portions per day. Meat, fish, beans and eggs contain the most protein Beans are very healthy as they contain high levels of protein and fibre, but do not contain much fat Proteins, which come from animals, are called complete proteins as they contain essential amino acids. However, our cholesterol level can rise if we eat too much red meat. Fats, oils and sweets are at the top of the pyramid: this means that we should not cat them too much. Remember that fats are contained in other food groups too. But not all fats are bad. Saturated fats like butter should not be eaten too often, but unsaturated fats like olive oil are good for us in moderation.
