What are some effects of omega-3s?

Scientists are studying omega-3s to understand how they affect health. People who eat fish and other seafood have a lower risk of several chronic diseases. But it is not clear  whether these health benefits come from simply eating these foods or from the omega-3s in these foods. Here are some examples ofwhat the research has shown.

Cardiovascular disease

Many studies show that eating fatty fish and other types of  seafood as part of a healthy eating pattern helps keep your heart healthy and helps protect you from some heart problems. Getting more EPA and DHA from foods or dietary supplements lowers triglyceride levels, for example.

The American Heart Association (AHA) recommends eating   one to two servings of seafood per week to reduce your risk of some heart problems, especially if you consume the seafood  in place of less healthy foods. For people with heart disease,the AHA recommends consuming about 1 g per day EPA plus DHA, preferably from oily fish, but supplements are an option under the guidance ofa healthcare provider. The AHA does not recommend omega-3 supplements for people who do not have a high risk of cardiovascular disease.
