High combined intakes of vitamin C and vitamin E, beta-carotene, lutein, and zeaxanthin from food may decrease the frequency of chromosome damage in ionizing radiation-exposed persons, a new study reports.
The study examined the association between the frequency of chromosome translocations, as a biomarker of cumulative DNA damage, and intakes of vitamins C and E and carotenoids in 82 male airline pilots (1). The results showed that high dietary antioxidant intakes were associated with a significant decrease in DNA damage induced by ionizing radiation (IR), a cause of cancer.
The intake of antioxidants, which can neutralize reactive oxygen species (ROS) generated endogenously or exogenously, has been extensively investigated in relation to DNA damage and cancer risk. Ionizing radiation (IR) is an established human cancer factor and an efficient inducer of chromosome abnormalities, which have also been shown to be associated with increased cancer risk in prospective studies. Airline pilots are exposed to elevated levels of cosmic IR.
During past decades, numerous animal or in vitro studies have suggested that antioxidants may provide protection against several forms of DNA damage induced by IR. To date, human data supporting these associations are limited. Of the dietary antioxidants, vitamins C and E and beta-carotene have been the focus of most research.

Iodine is an essential element of human nutrition and vital for the proper development of the central nervous system. The main sources of iodine in the European diet are dairy products and iodized salt. Latest findings reveal that pregnant British women suffer mild to moderate iodine deficiency at all stages of gestation, though the problem was found to be less evident in the wintertime when iodine levels in dairy milk are higher.
