We’ve been told to drink milk for strong bones our whole lives. However, a plate of kale may actually deliver calcium more efficiently.
Research shows that calcium from kale is more bioavailable than that from milk, meaning a greater fraction is absorbed and used by the body.
What Does Bioavailability Mean?
When we talk about calcium in foods, we usually focus on how much a food contains, but the number listed on the label tells only part of the story; bioavailability also matters.
