A new study out of Sweden has shown that compared with men who ate no fish, those that ate oily fish (herring, mackerel, salmon, whitefish, and char) once time a week were less likely to have heart failure. Interestingly, the authors found there was no benefit from eating 2 serving of fish compared with one serving.
For now, I will continue to tell my patient, following the recommendations of the AHA, that there appears to be a cardioprotective effect from eating oliy fish 1-2 x week. If you do this, there is probably no added benefit from taking Omega-3 supplements.
I will continue to update you on this as more data is available
