Re: [CR] Methionine restriction like CR?

[Guest guest]

Rod posted a study recently (post # 26058) that alluded to the ingestion of poultry and fish as having no detrimental effect on longevity, but that beef and pork did:

" Preliminary results are suggestive of a positive association of DNA damage with beef and pork intake and a negative association with cooked vegetable intake. "

Eighty-five percent is a high number! The findings mentioned in the

abstract are not very surprising. But, while I haven't seen the full

text, the abstract implies that consumption of fruit, fish, chicken

and *raw* vegetables are neither positively nor negatively associated

with DNA damage - which IMO is REALLY interesting. (Rodney’s words).

I searched the internet for the methionine content of dairy products as I eat some FF yogurt daily. I couldn’t find anything. If anyone has any data on this, please post it. Thanks.

If you look at the amino acid profiles of proteins, you will find that

whey, soy, and yeast have approximately 30% less methionine than eggs,

fish, beef, and chicken.

By just switching your protein sources to whey, soy, and brewer's

yeast you would be restricting methionine by 30%. If in addition, you

practiced a Pritikin diet instead of a Zone diet, your overall protein

consumption would be at least 10% to 15% lower still. This would give

you a an overall reduction in methionine of about 40 to 45%.

Hi Francesca:

IMO the best way to monitor methionine is to log what you eat into

CRON-o-Meter. After entering a day's food intake, click the 'amino-

acids' button and it will tell you exactly how much of each amino

acid you have eaten. And you can click on each food individually to

ascertain its contribution to the total.

I am working on the basis that one gram of MET a day may be a good

figure to aim for. But I cannot provide supporting evidence for

that. I rather doubt anyone has come up with a number for this yet

in the light of the very recent research showing the association

between methionine intake and lifespan, which has been published only

in the past year or so.

So, as so often happens, we each have to draw our own conclusions.

There may be a study saying the opposite tomorrow ; ^ )))

Although I can not claim to be cronning, I use this program and find it

helpful. Am I right in assuming that methionine is MET?

Hi Dennis:

I certainly hope so! Or I am very confused : ^ )))
