Studies suggest that broccoli, carrots, tomatoes, strawberries and whole grains may help prevent cancer, states WebMD. However, there is no credible evidence to prove that the foods can lower risks of cancer completely. Garlic and spinach may help prevent cancer as well.
Some research indicates that lycopene found in tomatoes may aid in reducing the risk of prostate cancer, stopping growth of tumors and boosting the immune system, states WebMD. Still-in-progress studies suggest that broccoli and other cruciferous vegetables can help lower risks of esophageal, mouth and stomach cancers.
Research shows that strawberries are enriched with flavonoids, which aid in protecting DNA and treating lung cancer, and antioxidants, which help in destroying carcinogens and inhibiting the growth of tumors, explains WebMD. Although studies are still in progress to determine how fiber reverses colorectal cancer, whole grains generally contain saponins, which prevent multiplication of cancer cells, and lignans, which inhibit oxidation. Cooked carrots contain high amounts of beta-carotene, which may help prevent toxicity and decelerate multiplication of cancer cells.
Garlic contains sulfur compounds that inhibit carcinogenic activity, destroy cancer cells and boost DNA repair, according to WebMD. Garlic counteracts bacteria that cause colon and stomach cancer. Unconfirmed studies suggest that spinach is enriched with carotenoids, including lutein, which help to counter free radicals in the body, lowering the risk of mouth, esophageal, ovarian, stomach and lung cancers.
