Longevity(Exceptional) - the genes have it

This recent press release has caused a world wide stir, with critics pointing out flaws in the analyses, though with the caveat that the identified flaws did not disprove the conclusions but raised questions that needed further investigation. In that link the researcher states his own research also identifies 150 specific markers in the exceptionally long lived. This more critical analysis though suggests the whole methodological approach is up the creek with one scientist quoted as saying the paper should not have been published because all the conclusions are suspect. The question is: Do we now know enough to enable people to realistically aim at extending their healthy lifespan? Not with studies like the above, but when the current centenarians were born people were only just becoming interested in the work of the quiet monk, Gregor Mendel, who pioneered modern genetics. Today we know so much more, and there is sufficient information to suggest it is possible to increase our lifespan and avoid illness. It is still a numbers game but we can play with the odds. First, some more of these genetic studies ... .

Oils Aint Oils: EPA for Depression

One of the more remarkable features about depression is the number of therapies that have proved beneficial. I explored that issue in this post. This latest study highlights the importance of prostaglandin regulation in depression. This latest study, the largest ever trial on omega 3 fats in treating depression, demonstrates a careful delineation that helps clarify the role of omega 3's in treating depression. The nutshell is this: they focused on EPA, typically at 120mg in your fish oil tablets, and boosted that intake to a big 1000mg per day. That's a lot but given the role of EPA in regulating prostaglandin pathways makes good sense.
