A new study asserts chocolate can improve cognitive performance joining research that indicates it can prevent heart attack and help you lose weight. But dig a little deeper and all is not what it seems
If theres one thing that people love more than chocolate, its science claiming that chocolate is good for you. The recently published is a study that determined a link between feeing chocolate and improved cognitive performance. However, given how much fat and sugar most chocolate also contains, are the reports of its benefits worth taking severely?
Makes you cleverer
This new study, based on virtually 1,000 people from New York, is not the first to connect chocolate to brain function, but what it actually tells us remains very vague. Its not possible to talk about causality, because thats nearly impossible to demonstrate with our design, said one of the researchers, meaning that we cant tell whether clever people like chocolate or chocolate attains you clever. Or indeed if there is something messier going on.
Helps weight loss
Can this really be true? It was surely widely reported last year, but in fact, the news turned out to be a swindle, perpetrated by the science journalist John Bohannon to prove how susceptible the media is to pseudoscience. Bohannon did conduct a real trial with some people feeing chocolate and some not, but he measured so many things about them that he knew some sort of fluke impact would probably show up. And what do you know? The chocolate-eaters happened to lose weight; the abstainers didnt.
Prevents heart attack and strokes
There are mountains of research papers claiming this to be true. Some, such as a 2012 analysis of 37,103 Swedish humen, seem quite authoritative, showing that the rate of stroke among middle-aged and older humen was 17% lower among those who feed a lot of chocolate, despite controlling for other factors. Still, the results werent statistically significant. And eating a lot of chocolate certainly is a good way to become unhealthily overweight probably better to hold off the Dairy Milk for now.
Research from UC San Diego is demonstrated that chocolate might act as a kind of performance-enhancing narcotic until you look at the detail. The 2011 study is really about a compound called epicatechin, which is present in chocolate, and its effect on mice, who are not people. Epicatechin dramatically improved the endurance of the mice while the issue is running on a treadmill. Whether this would translate to humen isnt known, but even if it did, youd probably required such a tiny dosage of epicatechin that it would be like feeing half a square of chocolate. Any more and the effect are to be able to reversed. It also has to be dark chocolate epicatechin is destroyed by the process of stimulating milk chocolate.
