A new theory has come up: Vitamin C may block growth of tumors by destabilizing their ability to grow under oxygen-starved conditions – according to a new study from a team from The Johns Hopkins University.
The team was alerted to a new possible mechanism of antioxidant functioning when it examined cancer cells from those cancer-implanted mice that were not fed antioxidants. There was an absence of any significant DNA damage in these mice.
This led the authors to suspect …read more

Pterostilbene (pronounced “tare-o-STILL-bean”) is a compound found in a genus of shrubs that includes many types of berries (including blueberries) and grapes that has been cited for its many health benefits:

pterostilbene can help lower cholesterol and prevent heart disease
pterostilbene is a powerful antioxidant that shows cancer-fighting properties similar to those of resveratrol

Such studies have been led by USDA/ARS Chemist Agnes Rimando.
Her recent study with colleagues at Poland’s University of Medical Science which tested pterostilbene (a derivative of resveratrol) and other resveratrols confirmed pterostilbene’s anti-cancer properties.
”…targeted an enzyme called cytochrome P450, which sets off a variety of compounds–known as “procarcinogens–that can …read more
