Munro or Monroe I read about maybe 35 years ago and the book was old then. Said we were carnivores, and furthermore used to live very long lives. When our ancestors began agriculture and eating wheat, etc, our lifetimes were reduced to what they are now. Kind of questionable, but Munro said eat all the meat, eggs you want, avoid everything with starch. Orange juice okay. I would not recommend this, just reporting.
Mine sounds like an updating of Munro's point of view with more data to back it up. But Munro's basic point was, and remains, correct.
