Consumer Reports has completed a review of the FDA testing on mercury levels found in canned tuna and issued new safety concerns. While the focus is on a clear alert for pregnant women and the damage mercury-contaminated tuna can cause to a developing fetus, mercury is also known to have an adverse effect on the immune system of adults. For anyone interested in cancer prevention, a healthy immune system is a vital first-line defense to keeping cancer from developing in the first place. Mercury, once consumed, can stay in the body for years. Because of the new information provided by Consumer Reports regarding the dangers of canned tuna, and because fish is an excellent cancer prevention food, here is a list of fish that have shown consistently low-levels of mercury during testing and are safe to eat daily. Wild salmon and tilapia can be safely eaten every day. Flounder, sole, mullet, Atlantic mackerel and crab can be safely eaten once a week. In addition, Consumer Reports found fish-oil supplements to be a safe, reliable way to get omega-3 fatty acids. You can check state agencies and the Environmental Protection Agency advisories for contaminant levels of fish caught where you live here.
