Dietary Nitrate:Where Is the Risk?

摘要

Links between nitrate and health risk have been studied for > 50 years,resulting in a large body of research.As two book-length reviews of the issue(Addiscott 2005;L'hirondel and L'hirondel 2001)tried to show,none of the health claims against dietary nitrate have been substantiated.If there was not already an established maximum contaminant level(MCL)of 10 ppm for nitrate in drinking water in the United States [U.S.Environmental Protection Agency(EPA)1991;World Health Organization(WHO)1958],it would be extremely difficult,if not impossible,to justify one based on the extensive evidence gathered to date.
