The 2015-2020dietary guidelines for americans recommend that pregnant women eat at least 8 ounces and up to 12 ounces of a variety of seafood lower in mercury a week. The average American consumes less than two to three times that amount. But a new study published in the Journal of the American Medical Association (JAMA) suggests that the amount of mercury in seafood is much higher than previously thought.
The study, led by researchers at the University of California, San Francisco (UCSF) School of Medicine, analyzed data from the National Health and Nutrition Examination Survey (NHANES), which is conducted every two years by the Centers for Disease Control and Prevention (CDC) to track the health and nutritional status of U.S. adults.
It found that seafood consumption was associated with a higher risk of developing high blood pressure, heart disease, type 2 diabetes and certain types of cancer, as well as lower levels of omega-3 fatty acids, a type of polyunsaturated fatty acid found in fish and shellfish.
