Modern man has conquered many of those issues.
The recent fish oil blood pressure study supports early recommendations concerning the benefits of Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA), as opposed to alpha-linolenic acid (ALA), which is found in vegetable oils. The study also confirms what others had suspected, an omega-3 called Docosapentaenoic acid or DPA is also beneficial for cardiovascular health.
Not all supplements contain DPA. Even the prescription omega-3 supplement LOVAZA contains only EPA and DHA. DPA is found primarily in species that live in very cold climates. It is important to note that the fish oil blood pressure studies indicate that the supplement is only modestly beneficial. If you suffer from mild hypertension, you will need to follow your doctor's recommendations, which probably include avoiding salt.
