The compounds in dark chocolate appear to be highly protective against the oxidation of LDL.
In the long term, this should cause much less cholesterol to lodge in the arteries, resulting in a lower risk of heart disease.
In fact, several long-term observational studies show a fairly drastic improvement.
In a study of 470 older men, cocoa was found to reduce the risk of death from heart disease by 50% over 15 years.
Another study revealed that eating chocolate two or more times per week lowered the risk of having calcified plaque in the arteries by 32%. Eating chocolate less frequently had no effect.
Yet another study showed that eating dark chocolate more than five times per week lowered the risk of heart disease by 57% .
A 2017 clinical trial found that subjects who consumed almonds with or without dark chocolate showed improved LDL cholesterol levels.
Of course, these four studies are observational, so it’s unclear exactly if it was the chocolate that reduced the risk.
However, since the biological process is known (lower blood pressure and oxidized LDL), it’s plausible that regularly eating dark chocolate may reduce the risk of heart disease.
Observational studies show a drastic reduction in heart disease risk among those who consume the most chocolate.
