We’ve previously recommended fish as a food that’s particularly good for your brain - in large part because it’s high in omega-3 fatty acids. 
While this holds true for many fish, one of the most popular, Tilapia, actually contains very little of the beneficial fatty acids according to new research from Wake Forest School of Medicine.
Instead, Tilapia is loaded with omega-6, which can cause inflammation that is bad for the heart. In fact, one of the authors of the study said, “the inflammatory potential of hamburger and pork bacon is lower than the average serving of farmed tilapia.”
So make sure your fish provides the right kind of fish fats! Some good options are Salmon, Mackerel, Trout, Whitefish, and Bluefin Tuna.

I think the key phrase in the study is “Chilton said tilapia is easily farmed using inexpensive corn-based feeds, which contain short chain omega-6s.” Corn-fed fish is the problem.
Research has already shown that grass-fed beef has a higher omega-3 content (with less omega-6) than corn-fed beef; so it stands to corn-fed fish will have the same high omege-6 content. I’d be interested in seeing how naturally raised tilapia rates.
