New meta study:
Chocolate consumption and cardiometabolic disorders: systematic review and meta-analysis
From 4576 references seven studies met the inclusion criteria (including 114 009 participants). None of the studies was a randomised trial, six were cohort studies, and one a cross sectional study. Large variation was observed between these seven studies for measurement of chocolate consumption, methods, and outcomes evaluated. Five of the seven studies reported a beneficial association between higher levels of chocolate consumption and the risk of cardiometabolic disorders. The highest levels of chocolate consumption were associated with a 37% reduction in cardiovascular disease (relative risk 0.63 (95% confidence interval 0.44 to 0.90)) and a 29% reduction in stroke compared with the lowest levels.
Based on observational evidence, levels of chocolate consumption seem to be associated with a substantial reduction in the risk of cardiometabolic disorders. ...

A few questions to ponder:
- Is it a real effect or are we witnessing a coincidental correlation, for example the "wealth" effect?
- If real, which factor contributed the most? One can think of several possible such as (a) cardiovascular-protective effects of coconut and cocoa butter, (b) resveratrol, (c) substitution of more harmful snacks and drinks (soda, beer etc), or some other yet unknown factor present in chocolate?
- What is the consumption quantity or threshold to produce a given effect. (The study did not have the means to quantify chocolate consumption in physical units, due to the lack of published data).
- Since the cardioprotective effect is comparable if not higher than the hugely popular statin drugs (according to the mainstream but questionable studies), it would be interesting to notice how eagerly will medical science community rush to conduct more studies on this topic. I am not holding my breath.
