About 35 percent of cancers are related to nutritional factors. To help prevent cancer, eat a wide variety of foods rich in nutrients that protect your body’s cells from damage, such as these.

A diet rich in fruits and veggies can help protect against many cancers. People who eat at least four servings of fruits have a 50 percent lower risk of cancer than those who consume no more than two such servings each day.

1. Red Apples
   Researchers found that red fruits such as red apples and vegetables protected against breast cancer in rats. Vitamins in fruits and vegetables with red skin can effectively inhibit production of cancer-promoting proteins and suppress the response of tumors to female hormones, thus reducing the risk of breast cancer.
2. Mango
   Research found that women who eat more mango have a lower risk of breast cancer. Researchers conducted a study of polyphenols, focused on bio-active ingredients called tannins, which prevent and inhibit cancer progression. Tannic acid, which is found in mango, is a kind of polyphenol with a bitter taste. It was found that polyphenols can disrupt the cell division cycle. Grape seeds and teas also contain polyphenols.
3. Citrus
   Citrus fruits such as oranges, grapefruit, lemon, kumquat are rich in vitamin C. Vitamin C can help prevent the formation of nitrosamine which may occur after eating processed meat. Vitamin C is good for patients with gastric cancer, laryngeal cancer, breast cancer and lung cancer.
4. Hawthorn
   Hawthorn is commonly used as an appetizer to boost digestion and lower blood lipids. It inhibits cancer cell growth and is rich in vitamin C. It’s good for the digestive tract and female reproductive system cancers such as gastric cancer and breast cancer.
5. Jujube
   Rich in B-carotene, vitamin C and B vitamins, this fruit contains a group of triterpenoids, an anti-cancer active ingredient. Jujube may be eaten in porridge or simmered with astragalus.
6. Kiwi
   Kiwi is a powerhouse of vitamin C. It has 4-12 times more vitamin C than an orange, 3 times more than an apple and 60 times more than grapes.
7. Avocado
   Contains Lutein (a carotenoid along with Vitamin E), Magnesium, and monounsaturated (healthy) fats. Avocado helps fight cancer of the mouth, breast, and prostate, and improves skin tone. It also improves absorption of nutrients in other foods.
