Although some foods contain calcium-binding substances such as oxalates and phytates, calcium absorption from foods is not a problem if you eat a balanced and varied diet.
Ideas for Action:
- If greens are significant calcium sources for you, be sure to rely on calcium-rich vegetables low in oxalates, such as broccoli, kale and bok choy or other mustard greens. Spinach is very high in oxalates so calcium in these greens is not available for absorption.
- Don’t worry about the oxalates in chocolate milk. There aren’t enough oxalates to interfere with the much larger quantity of calcium.
