Here is a link to an article that talks about farm-raised tilapia (I don't know what the stats are for wild tilapia). The article states that farm-raised tilapia has mostly omega-6 fatty acids - more than doughnuts or bacon - and very few omega-3 fatty acids. This can cause a lot of inflammatory problems.
Yikes! It seems I'm always reading that tilapia, along with salmon, is recommended for heart patients and others looking out for their health.
