People still mistakenly believe that eating a lot of protein from meat hurts your bones.
The reason is that some studies found that people would lose lots of calcium through their urine after eating protein.
Scientists have speculated for decades on the reason for all that calcium leaving people’s bodies. Way back in 1968, a piece published in The Lancet theorized that you use calcium from bones to counter the acidity produced when you break down the meat you eat when you digest it.
And the theory stuck.
But just speculating it was “because of meat” doesn’t make it true.
