WHO is being hard-headed, Blue?
From your source:
The absorptive efficiency of most vegetable sources is as good or better than for dairy foods, unless they have high concentrations of oxalic acid (spinach, for example) or phytic acid (wheat bran cereal, for example). Few vegetable sources are concentrated sources of calcium. Therefore, it would be difficult to obtain adequate intakes of calcium to protect against osteoporosis without liberal use of dairy products in the diet.
These lab scientists don't write very well, and the first sentence is misleading. But the basic point is that high-calcium veggies are easily absorbed, UNLESS they have high concentrations of oxalic acid or phytic acid. The real problem is that there are very few high-calcium veggies in general. Therefore, to get enough calcium to avoid osteoporosis, you'd better use dairy products. (Which is, basically, what I was saying.)

P.S. I aced my bone density test the other day! Did better than the 30-year old reference group average! And I smoked for almost 50 years! Must be all that yogurt I have been eating... |
