tuna

The mercury in tuna, especially certain brands) may damage the brains of infants, children, and adults (more than that in vaccinations, amalgam teeth fillings, high-fructose corn syrup and Ayervedic supplements). Tuna may also contain DDT (a banned pesticide still present in our food chain), PCB pollutants, and the carcinogens benzene and putrescine. Tuna sushi may contain fecal contamination in amounts exceeding National Food Standards guidelines. A toxin in tuna has even been found to cause a form of amnesia. So while tuna may be a source of heart-healthy omega-3, they may come packaged along with mercury contamination. One doesn’t have to worry about such contamination with algae-based sources of the long chain omega-3′s EPA and DHA.
