The purpose of this table (specifically in its spreadsheet form) is to help those who wish to pursue a low methionine diet, which has been shown to be increase the lifespan of many species independent of total caloric intake. Paul and Kitty Antonik Wakfer have used this analysis to greatly reduce their methionine intake. In order to maintain important methylation capability concurrent with reduction of dietary methionine (and no supplementation), it is suggested that one should supplement S-adenosylmethionine, which we are doing.
