>>> a story in the news today about fish oil and brain power . specifically, a new study that suggests fish oil may even slow the aging process in the brain. our chief medical editor dr. nancy snyderman is with us to talk more about this before people go on it and there is a run on fish oil . does this look to be what it is?
>> it's exciting. this study comes from ucla. basically, they did mri scans of the brain in about 1,600 people, average age about 67 years of age. in people showing no signs of dementia. what they found was stunning. people with low levels of omega 3 fatty acids had brains with less volume compared with people who had higher levels of the same fatty acids . they tested mention function and body mass and amount of omega 3 fatty acids in blood cells. people with lower levels tested poorly for blome solving, multitasking, visual memory and executive function , all things that could be hurt with dementia. while everyone agrees the best way to get your omega 3 fatty acids is with your diet, think fish. two 3 1/2 ounce servings of fatty fish from a salt water . these are the ones that are rich in omega 3 fatty acids . if you hate fish, there is something you can do. there is one time where supplements can work. the american heart association recommends a daily dose about 500 milligrams a day, which over a week adds up to the same two servings of fish. i think this one is, as we say, sort of a no-brainer.
>> nice to report good news.
>> yes, it is.
>> something people can do. nancy, thank you, as always.
