In a purely-medical Pajamas Media piece Dalrymple looks at a study on the effects of dark chocolate:
They produced a mathematical model of what would happen to their own patients at risk of cardiovascular disease if they took dark chocolate for medicinal purposes over a prolonged period. They worked out how many would have been expected to have fatal and non-fatal cardiovascular events (strokes and heart attacks) if they took no therapeutic chocolate; then they worked out how many would have fatal and non-fatal cardiovascular events if they took dark chocolate, on the presumption that the beneficial effects of that chocolate on high blood pressure and low-density lipoproteins persisted.They came to the conclusion that, if compliance was 100%, a regime of dark chocolate taken for 10 years by 10,000 people at high risk of cardiovascular disease would prevent 15 fatal cardiovascular events and 70 non-fatal ones. If compliance was only 90 percent, the figures would be 10 and 60 respectively.Of course, one must remember that this was a virtual trial, not a real one. As Goethe said, grey is theory, but green is the tree of life: in other words, full of surprises. It is possible that dark chocolate does not continue to exert a beneficial effect upon the risk factors for cardiovascular disease beyond 18 weeks. It is also possible that harmful effects of dark chocolate consumption would become evident after 18 weeks.
