According to Stone, this new study, funded by a grant from the Mountain States Health Alliance, is trying not only to determine if vitamin E can prevent colon cancer, but also what type is more effective. Consequently, most scientific efforts have concentrated on alpha-tocopherol in terms of how it might benefit one's health. But recent studies have forced scientists to take a second look at the role of gamma-tocopherol. And while in this state, the gamma-tocopherol does not lose its potential for being an antioxidant. That can mean a big difference, according to Stone.
Antioxidants are molecules that prevent free radicals from causing damage to the body.
The researchers will later obtain biopsies from all three groups to determine the levels of vitamin E present. If the theory proves to be true, it will confirm an idea Stone and Papas have shared for many years. An exciting aspect of this study, Stone noted, is the possible link to cardiovascular disease. The same enzyme which metabolizes gamma-tocopherol has been found to also lower blood pressure by enhancing sodium excretion. This would be very beneficial in preventing heart disease among patients who have high blood pressure.
