| Ray Peat PhD. showed that *pasteurized* dairy causes osteoporosis.

Even non-pasteurized dairy can upset the calcium: magnesium balance.

"In pre-agricultural diets consisting of meats, fruits, vegetables, nuts,
etc., the calcium (Ca) to magnesium (Mg) ratio is approximately 1:1. Because
the Ca:Mg ratio of milk and dairy products is 12:1, the inclusion of milk
and milk products into post-agricultural diets can raise the overall dietary
Ca:Mg ratio to 3 to 4:1 [Varo 1974]. In animal models, it has been shown
that rats develop clinical signs of magnesium deficiency after three weeks
on high-calcium, normal-magnesium diets

Ironically, high-calcium diets may have a deleterious effect upon bone
mineralization because of their hypomagnesic (magnesium-depleting) effect.
Conversely, magnesium deficiency is a known cause of hypocalcemia (low
calcium) [Rude et al. 1976]. (In other words, for either calcium or
magnesium utilization to be optimum, both must be in balance with each
other.)"
