Broccoli, cabbage, and cauliflower have a chemical component called indole-3-carbinol that can combat breast and prostate cancer by converting a cancer-promoting estrogen into a more protective variety.
Broccoli, especially sprouts, also have the phytochemical sulforaphane, believed to aid in preventing some types of cancer, like colon and rectal cancer. Sulforaphane activates a gene expression inside the cells that induces the production of glutathione and certain enzymes. This cellular antioxidant effect can neutralize free radicals and carcinogens. The enzymes have been shown to inhibit the growth of tumors in laboratory animals.
It appears that the more bitter the broccoli is, the more beneficial it is. Broccoli sprouts have as much as 20 times higher levels of sulfurophane that that found in mature heads of broccoli. In addition, broccoli, cauliflower, kale, brussels sprouts, and cabbage also contain two antioxidants, lutein and zeaxanthin, that may help decrease prostate and other cancers. In any case, it would be hard to eat enough broccoli to have the maximum protective effect. There are many excellent sulfurophane products on the market. One that we frequently recommend is Broccosabe from Pure Encapsulation.
What is resveratrol and can I get enough through drinking wine?
Resveratrol is a natural superior antioxidant compound found in abundance in red grapes (mainly the skins), grape seed extract, red wine, Japanese Knotweed, and peanuts. Nearly all the darker red wines, especially Pinot Noir, Merlot, Cabernet and Shiraz, contain far higher amounts of resveratrol than white wines or grape juice. Unfortunately, to get a valuable level of resveratrol by drinking red wine you would need to consume very large quantities and this would certainly be very detrimental to your health.
Resveratrol has recently been subjected to extensive research and experiments. It will take some time to definitely confirm that the hugely exciting and positive long-term health benefits of resveratrol on test mice will also affect humans in the same manner.
Recent research at the University of Nebraska identified resveratrol as one of the nutrients playing a role in inhibiting estrogen DNA adducts, a form of estrogen transformation in the body that increases risks for breast and prostate cancer.
