Besides that, you can also select a folder by right-clicking in the context menu or pressing ctrl+alt+f. Vitamin C can limit the formation of carcinogens, such as nitrosamines [2,29], in vivo; modulate immune response [2,4]; and, through its antioxidant function, possibly attenuate oxidative damage that can lead to cancer [1]. A follow-up AREDS2 study confirmed the value of this and similar supplement formulations in reducing the progression of AMD over a median follow-up period of 5 years [73]. The authors of a 2006 meta-analysis of randomized controlled trials concluded that antioxidant supplements (vitamins C and E and beta-carotene or selenium) do not affect the progression of atherosclerosis [66].

These findings applied to study participants who took relatively high-dose vitamin C supplements (approximately 1,000 mg/day) and not to those who took multivitamins containing substantially less vitamin C (approximately 60 mg/day).

Vitamin C deficiency is rare in developed countries but may occur with a limited diet that provides less than 10 mg daily for one month or longer. A pooled analysis of nine prospective studies that included 293,172 subjects free of coronary heart disease at baseline found that people who took 700 mg/day of supplemental vitamin C had a 25% lower risk of coronary heart disease incidence than those who took no supplemental vitamin C [62].

Throughout its history, C-SPAN has drawn call-in hosts from its ranks; they host the program in addition to other roles at the network. Epidemiologic evidence suggests that higher consumption of fruits and vegetables is associated with lower risk of most types of cancer, perhaps, in part, due to their high vitamin C content [1,2]. In healthy individuals, this does not appear to be a concern [8]. Arch Pediatr Adolesc Med 2007;161:978-85. Ft. 1104 Halls Stream Rd, Pittsburg, NH 03592. Overall, the evidence to date suggests that regular intakes of vitamin C at doses of at least 200 mg/day do not reduce the incidence of the common cold in the general population, but such intakes might be helpful in people exposed to extreme physical exercise or cold environments and those with marginal vitamin C status, such as the elderly and chronic smokers [81-83].
