The USDA is now saying if you eat less than five seafood meals per week you should be supplementing with fish oil. There are many, many ways that fish oil benefits the body, but here's one of the big reasons we all should be taking fish oil supplements. 60% of your brain is made up of fats. Your brain needs fats to thrive and stay healthy and if you feed yourself the healthy fats research shows that you "will not" pack on the pounds.
There are three kinds of omega-3 fats: DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid) and ALA (alpha-linolenic acid). While all are powerful anti-inflammatory agents the standout choice for brain health is DHA. EPA can be easily converted to DHA in the body while only about 10% of ALA is converted.
The question now is how much fish oil must we take. The USDA is recommending supplementation of 1,000 to 2,000 milligrams per day with at least 220 milligrams coming from DHA. If you are a regular fish eater then you may be able to take less.
