U.S. researchers from Rush University Medical Center in Chicago testing the association between vitamin B12 and brain function are saying that older folks with low levels of vitamin B12 may be more likely to lose brain cells and have cognition problems.

And while the study was on the small side...involving 121 people aged 65 and older...the findings were anything but small.

In fact, according to the article on vitamin B12 and brain function published in the journal Neurology four or five markers for vitamin B12 deficiency were associated with lower scores on cognition tests and smaller brain volumes over the four-and-a-half years that the volunteers were followed.

Brain shrinkage is linked with dementia or cognitive decline, which, of course is already a concern as we age. Scientists used to think that our brains naturally decreased in size as we got older and there wasn't a thing we could do about it, but newer research seems to indicate that as long as we remain healthy with an adequate supply of nutrients in our diet...like vitamin B12...this may not always be the case.

And here's where things get really interesting.

If you recall, just this past August I told you about a study that found that seniors are particularly at risk for being deficient in...yup, you've got it...B vitamins.

Now clearly we need more research in this area, but in the meantime if you're interested in naturally increasing your B12 levels the best sources by far are animal products including wild-caught salmon and snapper, liver, venison, shrimp, scallops, and grass-fed beef.

Bon appétit!
