A
Scientists are studying different foods, and they will see which foods protect us from cancer(癌症), and which cause it. It is known that a healthy diet(饮食) will help keep a healthy body weight, which can also decrease the risk(风险) of many types of cancer.
Fruit and vegetables
Fruit and vegetables are an important part of a healthy diet. They can decrease the risk of some cancer types like mouth and throat cancer. They are a good source of many important nutrients such as vitamin A, vitamin C, vitamin E, and are an excellent source of fiber.
Our advice
Try to get plenty of fruit and vegetables in your diet. Eating fruit and vegetables with a variety of colors will help you get many kinds of vitamins and minerals as the chemicals that give these foods their colors are good for you.
Meat
Eating lots of red and processed meat can increase(增加) your risk of stomach cancer. Red meat includes all fresh and frozen beef, pork and lamb. Processed meat includes ham, bacon and sausage. White meat, such as chicken, is unlikely to increase your risk of cancer.
Our advice
Eat smaller and fewer parts of red and processed meat. Try using beans or peas instead of meat in your diet. When you cook meat, use low-temperature methods.
Fat
Fat is a necessary part of our diet but high-fat diet can increase our risk of cancer, heart disease and other diseases. Meat is higher in saturated fat(饱和脂肪) and eating too much saturated fat may increase your risk of breast cancer.
Our advice
Try not to eat too much fatty foods. In particular, try to cut down on saturated fat contained in fatty meat, biscuits, and butter. Try to avoid frying foods in lots of oil.
