In the chapter on calcium by Heaney (well known vitamin D

researcher) and another author in Shills, et al., eds., _Modern

Nutrition in Health and Disease_ they state that it is estimated that

ancient hunter-gatherers eating mainly plant-based diets had intakes

of Ca of at least 1500 mg/day assuming typical caloric consumption and

possibly twice this if it is assumed that their caloric intake was

about doubled due to lifestyle/activity differences. I'm not sure

what they reference for it but I can look it up later. Interesting

food for thought since they are calculating this on the vegetarian-ish

assumption.

Don't forget it is not just bone *broths* that have calcium, but

bones, which might be more commonly eaten, especially in very small

animals and fish where bones are soft and edible.

Also, this seems completely illogical. What is the reasoning that

*calcium* intake would cause osteoporosis? I thought they usually

blame meat, even though research shows that high meat protein intakes

are clearly associated with higher calcium absorption, retention, bone

mineral density, and lower risk of fracture. This is based on an

outdated hypothesis that sulfur amino acids increase acid load and

thereby bone resorption, based on the observation that urinary Ca

increases on a high-meat diet, though it is now know that 80% of this

increase is due to increased intestinal absorption and that bone

resorption markers at least do not increase, and maybe decrease, and

that this is true even at protein intakes twice the standard

recommended amount of 0.85g/kg, which the vegetarians say are even too

high.

They simply haven't read their Stefansson or their Dr. Price, or even

bothered visitng native groups. Price and Stefansson both verified

the excellent health of the Eskimo/Inuit groups. Price's studies of

the Masai versus the Bantu clearly show much better teeth on a

high-meat diet. The only other options would be to call Price an

utter fool or a liar. Since he was probably the single most important

dentist of the 20th century, the fool accusation probably won't stick.

He certainly didn't win all that many friends by talking about butter

quality or how great meat and fish are, and how terrible canned foods

and vegetable oils are, so...he'd have to have some other reason to

lie, other than money or power. I certainly can't find one.

I will say that it is very important to get plenty of fat with your

meat. It's almost depressing to see the ultra-lean steaks and burgers

with nearly all the fat removed.

OTOH, it's very easy to see why the vegetarians lie. Their religion

either IS vegetarianism, or involves vegetarianism very heavily, like

being Seventh Day Adventist, or Buddhist. People lie to convert

people to their religions all the time.

I always think. . . cofactors as you said. I don't know what studies

you're referring to, but I know that Americans can pop calcium pills all

day long, but their diets are deficient in magnesium and D3, so they

don't use the calcium. Plus if they have a high phosphorus diet like the

SAD, doesn't phosphorus waste calcium, or prevent its absorbtion?
