Osteoporosis in Women: Foods Women Must Eat
Osteoporosis: Agents with a vengeance
The dietician tells you to watch out for foods that can stall the absorption of calcium in your body. “There are things in your diet that can interfere with how much calcium your body can absorb:
Phytic acid: This is found in unleavened bread, raw beans, seeds, and grains.
Oxalic acid: This is found in spinach.
Sodium: High levels of sodium will interfere with calcium retention; the higher your sodium intake the more calcium your body needs to meet its daily requirements, so it's best to keep your sodium intake down."
