I remember reading John Robbins “Diet for a New America” from the late eighties and getting the vegan opinion.
The veggies say that meat and dairy eating deluge us with low-quality proteins that DEPLETE calcium from our bodies and that on a veggie diet we get plenty without having to specifically load up on calcium.
Robbins pointed out a few of those primitive, turd-world cultures that eat mostly vegetarian diets with no calcium-rich foods who seemingly never have to worry about osteoporosis.
The turd-worlders probably get plenty of sun. Our ancestors made “Vitamin” D (really a hormone) from sunlight, but some of them migrated into regions where sunlight was dim and skin needed to be covered with insulation, so they need to get D from food.
“Robbins pointed out a few of those primitive, turd-world cultures that eat mostly vegetarian diets with no calcium-rich foods who seemingly never have to worry about osteoporosis.”
Maybe because they don’t live past 40.
