Modern “films” are digital
I’ve worried about the relatively low calcium content of most paleo diets. I see lots of little old ladies eating non-paleo with hip, spine, and wrist fractures related to the bone-thinning disease called osteoporosis. The bones break because they’re not adequately dense. Some experts think low calcium intake causes osteoporosis.
A Vietnamese study published in 2009 compared bone density of Buddhist nuns, who are vegans, with omnivorous controls. Dietary calcium content was 330 mg/day in the vegans, 682 mg/day in the omnivores. Nevertheless, bone density and osteoporosis prevalence were not significantly different between the groups. (Unfortunately, fracture rates were not reported.)
So perhaps the relatively low calcium content of paleo diets isn’t anything to worry about.
