There are MANY foods that have been shown to have positive effects on cancers, here are a few:
Red Grapes contain bioflavonoids, powerful antioxidants that work as cancer preventatives. Grapes also are a rich source of resveratol, which inhibits the enzymes that can stimulate cancer-cell growth and suppress immune response. They also contain ellagic acid, a compound that blocks enzymes that are necessary for cancer cells. This appears to help slow that growth of tumors.
Oranges and Lemons
Citrus fruits contain limonene which stimulates cancer-killing immune cells (lymphocytes, e.g.) that may break down cancer-causing substances.
Tomatoes contain lycopene that attacks free radicals that are suspected of triggering cancer. Scientists in Israel have shown that lycopene can kill mouth cancer cells. An increase intake of lycopene has already been linked to a reduced risk of breast, prostate, pancreas and colorectal cancer.
Garlic may contain chemicals capable of destroying cancer cells.
Beans contain phytochemicals and protease inhibitors that may help prevent cancer.
Sweet Potatoes contain lots of antioxidants, phytochemicals including beta-carotene, Vitamin C, Vitamin E, Folate, Calcium, Copper, Iron and Potassium that may help prevent cancer.
Mushrooms contain beta-glucan which stimulates the immune system. Shitake, enoki, zhuling and reishi all have anti-cancer effects.
Broccoli is rich in sulforaphane, an antioxidant linked with the reduced risk of a number of cancers such as lung, stomach, colon and rectal. By adding cheese or some other form of calcium increases it power. According to a Harvard study, premenopausal women who ate a diet rich in Vitamin D and Calcium had a 30% lower rate of breast cancer.
Raspberries, Black Raspberries, Cranberries, Blueberries and Blackberries
Berries are packed with fiber (the tiny seeds) and are high in Vitamin C. They also contain lots of anthcyanins which have been shown to be effective in slowing the growth of certain cancers.
The catechins in tea have been studied for their effectiveness in preventing cancer cells from dividing. Green tea proved to be the best, followed by black tea.
Melons are high in Vitamin C and Vitamin B6 and full of the antioxidant lycopene which may help to protect against cancer.
Carrots contain beta-carotene an antioxidant that may prevent cancer.
