Chocolate Linked to Weaker Bones ... But What Kind of Chocolate?
February 02, 2008
Regular consumption of chocolate could weaken bone density and strength, which could in turn increase the risk of osteoporosis.
According to a new study, women who eat chocolate daily have an overall bone density 3.1 percent lower than those who consume it less than once a week. More than 1,000 women aged 70-85 were asked to keep a diary of how often they consumed chocolate or cocoa-based drinks.
The researchers did not distinguish between types of chocolate consumed.
Even though chocolate contains flavonols and calcium, both of which are linked to a positive effect on bone density, it also contains oxalate, an inhibitor of calcium absorption, and sugar, which is linked to calcium excretion.
This study comes less than a month after British medical journal the Lancet warned consumers that manufacturers usually remove the healthy element -- the flavonols.
