Higher levels of the antioxidants beta-carotene and Vitamin C, along with the antioxidant trace mineral selenium, have been linked with a lower risk of asthma in a large study of 6000 American children under the age of 17, published in February 2004. The antioxidants showed even stronger protection against asthma in children exposed to passive smoke, said the researchers from Cornell University, New York.<\/p>\n
Vitamin E had little or no association with asthma. However, an increased beta-carotene intake was associated with a 10 to 20 per cent reduction in asthma in those not exposed to smoke, and a huge 40 per cent reduction in young persons who had passive smoke exposure. The pattern for Vitamin C was similar, as were the protective effects of selenium.<\/p>\n
