Some interesting links I thought I'd share

Milk:

This has a vegetarian spin, but sums up what I've read pretty well:
Milk, Calcium and Bone Density

You may want to skim (no pun intended! LOL!) this one, but it does have some interesting and seemingly unbiased information on milk consumption in children:
Milk: Can a "good" food be so bad?

The last paragraph has a lot of info
Calcium

"Diets that are high in protein cause more calcium to be lost through the urine. Protein from animal products is much more likely to cause calcium loss than protein from plant foods. This may be one reason that vegetarians tend to have stronger bones than meat-eaters."

Calcium in Plant Based Diets

Quinoa has a tremendous amount of calcium!
"A cup of quinoa has more protein than a quarter-pound hamburger and more calcium than a quart of milk. Yowza. It's also loaded with iron, magnesium, and a bevy of other minerals and B vitamins. No wonder the Incas named it "the mother grain." "
Wonder foods

Soy
A lot has been said about soy lately.... I haven't read these links yet, but I'm going to read through and I'll update later on my thoughts, if necessary....
