Contrary to popular belief, milk may increase the likelihood of osteoporosis.
It is still widely accepted that the calcium in dairy products will strengthen our bones and help prevent osteoporosis, but studies show that foods originating from animal sources (like milk) make the blood acidic. When this occurs, the blood leeches calcium from the bones to increase alkalinity. While this works wonders for the pH balance of your blood, it sets your calcium-depleted bones up for osteoporosis. As explained by John Robbins, "The only research that even begins to suggest that the consumption of dairy products might be helpful [in preventing osteoporosis] has been paid for by the National Dairy Council itself."
