Re: Re: Back to Methionine/chicken and ish

[Guest guest]

As I recall Rodney posted a study a few months ago that eating chicken and fish did not cause some unfavorable reaction(s) in the body that other proteins (milk, red meat) caused. Perhaps that’s a clue to fish eating by some of the world’s longest lived people. Also there are so many benefits to eating fish that perhaps the benefits outweigh any drawbacks. (Sounds to me similar to the controversy we have over red wine –i.e. Drinking several glasses a day in a couple of studies let to longer lives).

If anyone can dig up that post (Rodney?) please do. Perhaps it too belongs in the files.

The part that is always left out is cysteine which is " sister " part of the

methionine loop.

The other thing is the longest lived, the Japanese, supposedly eat lot of

fish.

Hi Tony:

Yes, I agree. In fact I discussed this very point in the piece I put in the

files on protein restriction:

'CRON Science' ...... 'DOES CR WORK THROUGH PROTEIN RESTRICTION?'

ugh%20Protein%20Restriction%3F

or: http://snipurl.com/2san9

The last part of which reads:

====================

" ............. BUT APART FROM THE BENEFIT OF CALORIC RESTRICTION, THE

ABOVE HAS YET BEEN CONCLUSIVELY DEMONSTRATED.

" Indeed there is some evidence which does not fit well with the methionine

hypothesis. For example, the most prolific sources of methionine in the

human diet are animal products. So, if the hypothesis is correct,

vegetarians and vegans should enjoy significantly extended lifespans

compared with meat eaters.

" While vegetarians and vegans on diets containing all essential nutrients

are healthy, PMID: 16441942, referenced by Jeff Novick in post #24225,

suggests their lifespans are not in fact longer than those of similarly

health-conscious meat eaters.

" So the evidence with regard to protein and methionine restriction is not

entirely one-sided.

" As always, we each have to make up our own minds where to place our bets,

based on our personal assessment of the evidence. Naturally, sometimes when

one bets, one loses. "

====================

So we still do not know to what extent this will/may affect the aging rate

in humans. That said, reducing one's intake of MET to around the RDA for

it (perhaps one gram a day) does not seem likely to have any downside. (My

opinion only, of course)
