食物金字塔

食物金字塔 A "Food Guide Pyramid" is a guide for healthy eating. The pyramid shape shows the proportions (比例) of various food groups that we all need in our diet. Food groups at the bottom of the pyramid are to be eaten more than food groups nearer the top. Bread, cereal (谷类), rice and other grains are a good source of carbohydrates (碳水化 合物). They give us the basic energy we need for our active lives. Vegetables provide vitamin A and C, carbohydrates and fibre. They are needed to help us fight many diseases, including cancer. Fruit also supplies vitamin A and C, and minerals, which keep our skin, eyes and gums (齿龈) healthy. Milk, cheese and yoghurt (酸奶)— the dairy group — provide protein, calcium (蛋白 质和钙) and vitamin D. These are all needed for strong bones, teeth and muscles. Meat, fish, eggs and nuts supply protein, iron, vitamin B and minerals for strong muscles and healthy blood. But what about the snack food (零食) that we all enjoy, like chocolate and candies (糖 果)? Small amounts of candy, soft drinks (不含酒精的饮料), and other sweets can be eaten occasionally (偶尔) if you fill up on food from the basic food groups first. But remember, this type of food should not be eaten every day. Try snacking (吃零食) on food that come from each of the different food groups, especially fruit.
