Milk Does Not Protect
Against Bone Breaks AdAmericans did a double-take on PCRMs ad, which
appeared on subway trains and station platforms, in newspapers, and on the Internet in
March. Yes, its true. The Harvard Nurses Health Study, including 77,761 women,
aged 34 to 59 and followed for 12 years, showed that those who got more calcium from milk
actually had slightly, but significantly, more fractures, compared to those who
drank little or no milk.1
A 1994 study of elderly men and women in Sydney, Australia, showed much the same
thinghigher dairy product consumption was associated with increased fracture
risk. Those with the highest dairy product consumption had approximately double the risk
of hip fracture, compared to those with the lowest consumption.2
This does not mean that calcium is not important. But it does mean that dairy products
do not protect against bone fractures, according to the best evidence we have. Good
nondairy sources of calcium include fortified orange or apple juice, green leafy
vegetables, beans, and calcium supplements. And, no, you dont need to eat six cups
of kale. There are plenty of calcium choices. Just as important, reducing sodium (salt)
intake, avoiding animal protein, and quitting smoking helps your body keep calcium where
it belongs instead of losing it through the kidneys into the urine.
