Taking daily supplemental doses of vitamin C does not significantly affect the common cold, according to a new review of 30 past studies, with one exception: People exposed to periods of high physical stress, such as marathon runners and soldiers on sub-Arctic exercises, are 50 percent less likely to catch one if they take C supplements.
Aside from colds, diabetics may have a new reason for making sure they drink orange juice. University of Buffalo (New York) researchers say they have found that OJ, despite its high caloric load of sugar, helps diabetics battle oxidative damage to their cells.
The high-sugar negative of orange juice is countered by its abundant flavonoids - chemicals that suppress destructive oxygen free radicals. An overabundance of free radicals can damage cells, contributing to the development of many diseases, including diabetes.
"Our data are relevant to patients with diabetes because stress from (free radicals) and inflammation are increased in this population and may contribute to development of atherosclerosis," Dr. Paresh Dandona said. "Clearly the choice of foods that either don't increase or actually decrease oxidative and inflammatory stress is important."
