SAMA HOOLE: Calcium absorption from spinach: about 5% due to oxalates. Calcium absorption from dairy: 30-35%.

Calcium absorption from spinach: about 5% due to oxalates.

Calcium absorption from dairy: 30-35%.

You'd need to eat 16 cups of spinach to get the bioavailable calcium in one glass of milk.

Nutritional databases don't tell you this.
