Introduction: Food not only can satisfy one's hunger, but can also play an important role in health-care. Different kinds of food have different nutrition and effects. Traditional Chinese medicine recommends the following five kinds of food, which can protect your health and make you away from some diseases.

1. Berries
According to the study of U.S. Department of Agriculture, it shows that blueberry contains the highest content of antioxidant in all the fruits, and the second is cranberry, followed by blackberry and strawberry. Antioxidants can neutralize the free radicals in the body. These free radicals can cause chronic diseases such as cancer, heart disease and so on. What's more, berries, especially cranberry, can also prevent catheter infection.

2. Dairy products
Dairy products not only can provide human body with a lot of calcium, but also contain a large number of protein, vitamins (including vitamin D) and minerals. All of these nutrients are the key elements to prevent osteoporosis. American nutritionists suggest that people should take in three kinds of low-fat dairy products every day, which can make the bones much stronger.

3. Fish
Fish such as salmon and tuna contains a large number of Omega-3 fatty acid. This fatty acid can fight against diseases, and help reduce the amount of fat in the blood. At the same time, it can also prevent clotting which has something to do with heart disease.

4. Vegetables
Vegetables are also one of the best food to resist against diseases. These vegetables include spinach, kale, cabbage, lettuce, and so on. They contain a variety of nutrients, such as vitamins, minerals, β-carotene, vitamin C, folic acid, iron, magnesium, carotenoids, phytochemicals, antioxidants, and so on. A study has found out that, if you often eat some food which contains a lot of magnesium, such as spinach, it can reduce the possibility of diabetes.

5. Whole grains
Whole grains include whole wheat, barley, rye, millet, brown rice, and so on. These whole grains contain various kinds of nutrients, including folic acid, selenium and vitamin B, all of which are beneficial to the health of the heart. At the same time, these nutrients can also control your weight and reduce the risk of diabetes. In addition, whole grains contain plenty of dietary fiber, which can give you a sense of satiety, so that you will not feel hungry between meals. What's more, the high content of dietary fibers can also promote the digestion of food.
