Comparative Physiology: Maximum Lifespan

A conundrum if the amino acid methionine is a determinant of maximum lifespan: Why do carnivores and vegetarians live the same? Perhaps it could be for different reasons.... antinutrients for the latter and methionine for the former. These are universal rules that apply even between disparate physiologies. I haven't been able to find any papers that examine methionine diet content versus longevity.

This is a valuable resource on important "carninutrients" lacking in vegetarian diets.
