Great Sources of Calcium

Dark green vegetables, such as broccoli and collard, mustard, and turnip 
greens are much better sources of calcium than milk. A single cup of 
broccoli contains almost a fourth of the U.S. RDA of calcium. Another good 
source is calcium-fortified orange juice. Beans and tortillas are also
good sources of calcium.

Some people do need hormone treatments and/or calcium supplementation for 
varying conditions. The risks and benefits should be discussed with one's 
doctor.

**my note--some tofu is made with Calcium nitrate as the coagulant, and 
is therefore a good source of calcium.  Some tofu is made with nigari as 
the coagulant, and does not have much calcium.  Read the label.
