Eating animal protein is way too acidic for human bodies. We sacrifice our bones each time we consume meat. Our bones are made up of calcium phosphate, and we take in all the acidity when we eat, so the phosphate has to leech from our bones to neutralize the acidity, meanwhile we actually loose calcium when we pee. This results in weaker bones.
"Approximately 10 million Americans have osteoporosis and another 44 million have low bone density, placing them at increased risk. 54 million Americans, half of all adults age 50 and older, are at risk of breaking a bone and should be concerned about bone health."
