Introduction of Resveratrol
While the health benefits of resveratrol seem promising, one study has theorized that it may stimulate the growth of human breast cancer cells, possibly because of resveratrol’s chemical structure, which is similar to a phytoestrogen. However, other studies have found that resveratrol actually fights breast cancer. Some studies suggest that resveratrol slows the development of blood vessels which supresses tumors, but also slows healing. A small study found that a single dose of up to 5 g of trans-resveratrol caused no serious adverse effects in healthy volunteers.
