Re: Methionin restriction like CR

[Guest guest]

When I look at that table on amino acid profiles that Tony refers to, I get an even better picture for soy. Soy has 1.3 % methionin in weight of total amino acids, vs 2.6 - 3.0 % for beef, chicken and tuna, which gives a methionine reduction of at least 50 %. Coupled with some over-all protein restriction and you get down 60 % or more.

"If you look at the amino acid profiles of proteins, you will find thatwhey, 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'syeast you would be restricting methionine by 30%. If in addition, youpracticed a Pritikin diet instead of a Zone diet, your overall proteinconsumption would be at least 10% to 15% lower still. This would giveyou a an overall reduction in methionine of about 40 to 45%.Amino acid profiles of food proteins:http://www.scientificpsychic.com/fitness/aminoacids1.html "Tony
