How do high concentrations of oxalates, found in foods like spinach, negatively affect calcium utilization?

Answer

They bind with calcium, rendering it unavailable for absorption before it can enter the bloodstream.

Oxalates sequester calcium that is present in the digestive tract. This binding action prevents the mineral from being absorbed, regardless of how much calcium is present in the overall diet.
