Dietary supplements use and risk of cancer mortality: A review of epidemiological studies / 肿瘤

ABSTRACT

Researchers have realized that a diet rich in vegetables and fruits was closely related with incidence and mortality of cancer since the 1980s, and have been studying whether taking dietary supplements can reduce the risk. Although some results of the animal experiments were remarkable, the outcomes in cohorts and randomized controlled trials were not accorded with the expectations. This paper reviews the progression in epidemiology of the relationship between the dietary supplements, especially antioxidant supplements, and the risk of cancer mortality for the long-term use of dietary supplements in Chinese residents.
