This may explain the overwhelming representation of vegetarians and near-vegetarians in the centenarian population. Perhaps a plant-based paleo approach would be best for longevity to avoid the complications associated with grain and legume intake we see in typical vegetarian/plant-based diets.
I read recently someone postulating on this issue. They made the comment that perhaps the protein intake necessary for high strength based sport/lifestyle was contraindicated for longevity by definition.
Vegetarian leanings (not total, but not "paleo") seem to provide more consistent longevity. Perhaps a high strength, super active lifestyle is not most conducive to living a long time...
I'll need to look more into this before I draw conclusions. Though I am leaning more and more towards this conclusion...
