Summary
Brief summary
Bone loss occurs at an accelerated rate in women after the menopause. This has been attributed to reduced calcium absorption in the gut and increase excretion of calcium in the urine. This bone loss may be greater in those on low calcium diets compared with those on high calcium diets. This has been shown in animals and some human studies have been able to link low lumbar spine density to low calcium diets.
