The potential of vitamin C has again been highlighted in a new study. This time vitamin C from dietary sources is associated with up to 50% lower risk of pre-malignant oral lesions in men.
The study published in The International Journal of Cancer analyzed vitamins C, E, A and carotenoids intake in diet and supplements for 42,340 men enrolled in the Health Professionals Follow-up Study over and the occurrence of oral pre-malignant lesions.
Researchers from the New England Research Institutes, Watertown, Massachusetts, found men with the highest intake of dietary vitamin C had a 50 percent reduction in risk compared to those with the lowest intake, of oral premalignant lesions.
No such reduced risk was found with vitamin C supplements, indicating multiple factors at work in vitamin C rich foods.
