Molecular mechanisms for the anticancer activity of the carotenoid lycopene
There is extensive and consistent evidence that high intake of fruit and vegetables is associated with decreased risk of many types of cancers. Thus, it is widely accepted that diet changes are a powerful tool for cancer prevention and for inhibition of cancer progression. The growing interest in the role of the tomato carotenoid, lycopene, […]

Effect of vitamin E, vitamin C, and beta-carotene on stroke risk
In a recent prospective observational study, vitamins C and E and beta-carotene did not elicit protective effects on stroke risk. Lutein, however, may elicit such protection. Nevertheless, these nutrients may be important modulators of the outcome after the occurrence of a stroke. At present, optimal control of the classic stroke risk factors in combination with […]

Chemoprevention of cancer: lessons to be learned from beta-carotene trials
Observational studies indicate a lower incidence of chronic diseases, including various cancers and cardiovascular disease, related to higher intakes of carotenoid containing foods (fruits and vegetables). Beta-carotene, one of the large number of naturally occurring carotenoids, thus appears to actively participate in health. However, recent intervention trials indicate that beta-carotene supplements are not efficacious in […]

Chemistry and biological effects of dietary phenolic compounds: relevance to cardiovascular disease
1. There has been considerable recent interest in the possibility that increased intake of dietary anti-oxidants may protect against cardiovascular disease. This is partly due to the knowledge that oxidative events in vivo may play a role in the pathogenesis of atherosclerosis. 2. While dietary anti-oxidants, such as vitamins E and C, have received considerable […]
