Washington: Mercury in diets could whittle down the power of antioxidants and cause serious threats to health by accumulating in the body, aver scientists.Antioxidants, playing a critical role in protecting cells, could also -- if they are not functioning properly -- damage them or cause their deaths.This damage, known as oxidative stress, is tied with Alzheimer`s, Parkinson`s disease and diabetes, the journal Environmental Research Letters reports.As such, antioxidants are widely used in dietary supplements and have been investigated in the prevention of cancer and cardiovascular disease, according to a University of Alaska statement.University of Alaska Fairbanks researchers analysed groups of 12 huskies, a working dog breed, in four villages each with similar lineage, sex and age and in their peak racing years.These huskies are exposed to the same environmental hazards as humans, sharing similar responses to ageing, immune function, toxicology and cognitive disorders.
