A new study published in the journal Neurology is re-confirming what moms and grandmoms have already long known...and that is the benefits of fish oil for the brain.

Researchers were actually looking at the levels of omega-3 fatty acids, a nutrient commonly found in fish, in the diets of 1,575 people with an average age of 67.

They found that the volunteers who had lower blood levels of omega 3's also had lower brain volumes. In fact, their brains appeared to be about two years "older" than their counterparts who had higher omega-3 levels. And the omega-3 deficient people scored lower on tests of visual memory, problem solving, multi-tasking, and abstract thinking.

And the moral of this fish tale is...yup, you guessed it...eat more fish! You can also up your omega 3's by taking a quality fish oil supplement and receive all of the benefits of fish oil for the brain found in this study. Just be sure to take vitamin E as well to zap any potential free radicals.
