On Wednesday 23th of March a new analysis revealed that the level of mercury from fish sources is not associated with cardiovascular disease, stroke or with a high risk of heart problems. Scientists from different institutions such as (Harvard School of Public Health and Brigham and Women's Hospital in Boston) gathered information from 2 separate studies about men and women lifestyles, diseases incidences, medical histories and more than 173,000 responds were collected.
Researchers examine toenail clipping of 3500 cardiovascular patients and 3500 other people without the disease, both men and women. Afterward, they measured mercury and selenium concentrations in the toenail samples of the heart patients. The selenium shows to protect against the mercury poisoning.
The conclusion was released in the New England Journal of Medicine that no proof were found in the study that mercury exposure can affect coronary heart disease patients. Fishes such as swordfish, tilefish and mackerel tend to stock up more methyl mercury. Thus the U.S. Food and Drug Administration has recommended pregnant women, toddles, and nursing mothers to limit their consumption of these fishes and other seafood. Fish is good for health as it contains omega-3 fatty acids and needs to be included in a meal twice a week for a balance diet.
