A chemical found in red wine and heralded for its cancer and heart disease fighting abilities is unlikely to work at all on most cancers, according to a small study. Researchers unveiled results showing that resveratrol, an antioxidant found in grape skins, wine, and peanuts, barely enters the human bloodstream when taken by mouth. Laboratory studies have shown that the chemical can kill cancer cells or inhibit their growth. But without remaining in the blood, researchers say the drug is highly unlikely to exert any effect on breast cancer, prostate cancer, or heart disease as many marketers claim.
