*Green leafy vegetables that contain oxalic acid should not be considered good calcium foods, even though they might contain large amounts of calcium. The oxalic acid in vegetables such as spinach, parsley, beet greens, and purslane limits the calcium absorption from these foods.
**Bones must be well-cooked to extract calcium.
