Hi Alan,

you mentioned he ratio Ca/P. I checked in the USDA database (I know,
Rex, they are not very reliable), and I found

(Ca and P are expressed in milligrams per 100 grams of food.)

                       Ca    P     Ca/P
Milk, goat           133.5 110.7    1.2
Milk, human, mature   32.2  13.7    2.3
Milk, indian buffalo 169.0 117.4    1.2
Milk, sheep          193.4 158.0    1.2
Milk, cow            100.8  85.5    1.2

Broccoli              48    66       .7
lettuce, romaine      36    45       .8
celery                40    25      1.6
parsley              138    58      2.4
Grapes, american      14    10      1.4
type (slip skin)
figs                  35    14      2.5
bananas                6    20       .3
cucumber              14    20       .7
tomato                 5    24       .2

Thus, I don't see any evidence that cow's milk has a lower Ca/P ratio
than fruits or vegetables.

I think that the main causes of osteoporosis in women are: menopause,
lack of vitamin D, and lack of exercise; total calcium intake is less
important.
