Does chocolate make you clever
Their presence in our food is said to have a positive impact on some chronic pathologies, and on our cardio-cerebra-circulatory system. A higher intake of dark chocolate was also linked with less likelihood of having MCI.
In the last five years they began tracking dietary habits as well, which inspired Dr. While such results are promising, not all chocolate studies have found evidence of cognitive benefits.
It found that people who scored better than average on these tests said they ate chocolate more often than people who scored worse than average on the tests. Mr Elias began studying the cognitive abilities of more than 1, people in the state of New York in the s, initially looking at the relationship between people's blood pressure and brain performance. Before getting too carried away with the supposed health benefits of chocolate, it's worth remembering that chocolate also contains lots of sugar and fat, so should only be eaten in moderation. Reuters Of all the chocolate research out there, the most unabashed tribute to the "dark gold" has to be a study just published in one of the world's most prestigious medical journals. One hypothesis is that these ingredients in chocolate may increase blood flow to the brain which improves its function. The correlation between increased cognitive ability and chocolate intake remained even after controlling for age, sex, education, blood pressure, cardiovascular risk factors, and a few other dietary habits like alcohol intake. We can't be sure chocolate was the only factor that mattered. That is really some of the concern here. Franz H. It's one thing if you want like a medicine or chemistry Nobel Prize, OK, but if you want a physics Nobel Prize it pretty much has got to be dark chocolate.
After eight weeks, those in the high-flavanol group, and to some extent the medium-flavanol group, did better on tests measuring different aspects of cognitive function, including verbal fluency, compared with those in the low flavanol group—though even the low-flavanol group showed some improvement compared to baseline.
We also don't know how much chocolate people ate only how often they ate it or what type — whether it was dark, milk or white chocolate.

However, The Guardian took a more sceptical approach, saying the results were "very vague" and taking the opportunity to question other health claims made for chocolate. In the conflict of interest section of his article, Messerli, who is of Swiss origin, "admits to daily chocolate consumption. As part of this study, participants filled in food questionnaires and undertook brain function tests from to It falls in line with a study piloted since the 70s, the Maine-Syracuse Longitudinal Study. They are also said to be excellent memory aid, since they play an active role of vasodilator, which seems to improve blood flow and is good for irrigating the brain and making it work. Lead researcher Georgina Crichton was quoted in the media as saying that the benefits of this would make someone better at daily tasks, "such as remembering a phone number, or your shopping list, or being able to do two things at once, like talking and driving at the same time". The study was published in the peer-reviewed journal Appetite. About 15 years ago, he decided to ask participants of the Maine-Syracuse Longitudinal Study MSLS what they were eating, adding a new set of questions about dietary habits. The study used a specially formulated cocoa extract produced by Mars Inc. We can't be sure chocolate was the only factor that mattered. For example, they did not differentiate their results for those who ate light vs dark chocolate. However, as is so often the case, the reality is less clear than the headlines suggest. Nor is it known who might benefit most from chocolate in terms of age and cognitive health for example, those who already have some cognitive decline versus those who are cognitively healthy.
Further analysis supported a causal relationship between chocolate intake and better cognition, ruling out the possibility that people with better cognition to begin with simply tended to eat more chocolate.
Conclusion Studies suggesting that chocolate is good for us always grab the headlines.
Our best chocolate cake recipes. Cocoa powder that is Dutch- or alkali-processed as many are loses much of its flavanol content.
Tests of verbal memory showed no link to chocolate consumption. Freak Correlations Messerli, who runs the hypertension programme at St.
Does chocolate affect your brain chemistry
The study received widespread and mostly uncritical coverage by the UK media. Cocoa caveats These and other chocolate studies have a number of shortcomings. This was a cross-sectional analysis of data from a big cohort study , which follows people through time. Since then, several other studies described below have looked at the relationship between cognition and chocolate which consists of cocoa powder, cocoa butter, and other ingredients or cocoa the chocolate component that contains the flavanols. They wanted to see whether intelligence scores could predict whether or not people said they ate chocolate frequently. Franz Messerli, who did the analysis. They then looked to see whether brain test results varied according to how often people said they ate chocolate. CocoaVia is a proprietary cocoa extract, sold by Mars as a dietary supplement. We also don't know how much chocolate people ate only how often they ate it or what type — whether it was dark, milk or white chocolate. More research is needed to determine which compounds in chocolate may be beneficial to the brain—several of them may work together synergistically.
The link was so strong it made a joke out of a statistic that virtually all studies in medical journals hinge on - the so-called p-value. The Independent and Daily Express both said that the study gave "proof" that chocolate made people more intelligent, while The Daily Telegraph and Daily Mirror said chocolate "can make you smarter".
They have far fewer calories than chocolate and an abundance of vitamins and minerals, along with fiber and other healthy plant compounds.

Examining the mean scores on cognitive tests of participants who ate chocolate less than once a week and those who ate it at least once a week, the researchers found eating chocolate was strongly linked to superior brain function. Flavonoids are said to boost brain activity With natural compounds that can be found in plants, flavonoids help repair their injuries and make sure they are protected against danger represented by diseases and parasites. However, previous studies have shown that food containing nutrients called flavanols, such as chocolate, improves brain function. Messerli , cardiologist and director of Clinical Hypertension with St. The researchers took account of a few variables that could affect the results — such as people's education level, age, sex, overall diet and cardiovascular risk. More research is needed to determine which compounds in chocolate may be beneficial to the brain—several of them may work together synergistically. Their presence in our food is said to have a positive impact on some chronic pathologies, and on our cardio-cerebra-circulatory system.
