Chocolate bad for bones, evidence shows

There is increasing evidence that chocolate is good for the heart, but new research suggests it may not be so great for your bones.

A study in the American Journal of Clinical Nutrition found older women who ate chocolate every day had weaker, thinner bones than their peers who indulged less frequently.

The difference didn't appear to be due to overall dietary habits. Researchers say chocolate contains something called oxalate which blocks the absorption of calcium and sugar which can boost calcium excretion.

Researchers say this study raises concerns that frequent chocolate consumption may increase the risk of osteoporosis and fractures.
