Causes severe bone loss.
Quote:Chocolate contains oxalate — a naturally occurring compound in cocoa beans — which can inhibit the absorption of calcium.
Quote:Higher frequency of chocolate consumption was linearly related to lower bone density and strength (P < 0.05). Daily (≥1 times/d) consumption of chocolate, in comparison to <1 time/wk, was associated with a 3.1% lower whole-body bone density; with similarly lower bone density of the total hip, femoral neck, tibia, and heel; and with lower bone strength in the tibia and the heel (P < 0.05, for all). Adjustment for covariates did not influence interpretation of the results.
