Guest guest Posted August 27, 2007 Report Share Posted August 27, 2007 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). See the entire post here: /message/26058 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. From: citpeks <citpeks@...> Reply-< > Date: Sun, 26 Aug 2007 22:36:15 -0000 < > Subject: [ ] Re: Fw: [CR] Methionine restriction like CR? 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%.

Guest guest Posted August 27, 2007 Report Share Posted August 27, 2007 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 ; ^ ))) Rodney. > > 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.
