QUOTE : With modern Western diets, the body must work hard to keep the blood from becoming overly acidic from the excess animal protein being eaten. To do this, it uses alkaline bone tissue substances such as bicarbonates and calcium. This can lead to the loss of bone density and helps explain the high rates of osteoporosis in cultures where people eat large quantities of acidifying animal foods. Osteoporosis rates among the Eskimo people, who eat an almost completely flesh-based diet, are among the highest in the world.18 Next are northern Europeans and North Americans, who eat high quantities of flesh, eggs, and dairy products.19 While there are other factors that may affect bone health, such as vitamin and mineral intake, levels of loadbearing exercise, and mental and emotional factors, there is evidence that brittle bones and osteoporosis are correlated with eating the large amounts of animal protein typical of our meals.
