Health groups have been recommending that Americans eat two servings of fish a week to increase their intake of heart-healthy omega-3 fatty acids.
But is farmed fish included in that recommendation?
New research shows that farm-raised tilapia, a popular fish, may actually harm your heart due to low levels of healthy omega-3 fatty acids and high levels of unhealthy omega-6 fatty acids, according to U.S. News and World Report. The study was published in the July issue of the Journal of the American Dietetic Association.
The new research is particularly important for patients with conditions such as heart disease.
Senior study author Dr. Floyd H. Chilton is quoted in the article: "If you're in a vulnerable population such as a heart disease patient, you need to be very careful with what you're eating, and that includes everything. But when it comes to fish, there's not a more important thing you can do for heart disease than eat the right type of fish or take dietary fish oil. There is evidence that you may harm yourself by eating the wrong kind of fish, and [farmed] tilapia and catfish are the two that fall into that category."
The article suggests that no one has really looked at the nutritional effect of an explosion in farmed fish (increasing at an annual rate of 9.2 percent, compared with 1.4 percent for wild fish).
