If there is a crucial "signaling" function of DHA in the brain, there would have to be rapid turnover, as most seem to believe, but then the "EFAD" people would have severe cognitive and/or other dysfunctions. I don't see evidence for this supposed function, assuming Mead acid is there instead. There may be tiny amounts of DHA in eyes or brain, which could explain strange cravings by pregnant women, but if significant amounts are needed, I would have experienced some problems by now (and my great grandparents wouldn't have lived so long and/or so well). |
