Can chocolate make you smarter?( And thinner? And healthier ?)

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.

Improves fitness

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.

The dark truth about chocolate

Grand health claims have been made about chocolate, but while it dedicates us pleasure, can it really be good for us?

Chocolate has been touted as a treatment for agitation, anaemia, angina and asthma. It has been said to awaken craving and act as an aphrodisiac. You may have noticed we’re still on the letter A.

More accurately, and to avoid adding to considerable existing embarrassment, it is the seeds of the Theobroma cacao tree that have, over hundreds of years, been linked to remedies and therapies for more than 100 diseases and conditions. Their status as a cure-all dates back over 2,000 years, having spread from the Olmecs, Maya and Aztecs, via the Spanish conquistadors, into Europe from the 16 th century.

The 19 th century ensure chocolate drinking become cheap enough to spread beyond the wealthy, the invention of solid chocolate and the development of milk chocolate. Afterward came the added sugar and fat content of today’s snack bar and Easter eggs, which time-travelling Aztecs would probably struggle to associate with what they called the food of the gods.

Recent years have watched chocolate undergo another transformation, this time at the hands of branding experts. Sales of milk chocolate are stagnating as consumers become more health-conscious. Producers have responded with a growing range of premium products promoted with such terms as organic, natural, cacao-rich and single-origin. The packets don’t say so, but the message we’re supposed to swallow is clear: this new, improved chocolate, especially if it is darknes, is good for your health. Many people have swallowed the idea that it’s a “superfood”. Except it isn’t. So how has this magic trick-like metamorphosis been achieved?

Its foundations lie in chocolate manufacturers having poured huge sums into funding nutrition science that has been carefully framed, interpreted and selectively reported to cast their products in a positive sunlight over the last 20 years. For instance, analyses published last year observed chocolate consumers to be at reduced danger of heart flutterings, and that women who feed chocolate are less likely to suffer from strokes. Ingesting chemicals called flavanols in chocolate was also linked to reduced blood pressure. In 2016, eating chocolate was linked to reduced dangers of cognitive deterioration among those aged 65 and over, while cocoa flavanol consumption was linked to improved insulin sensitivity and lipid profiles- markers of diabetes and cardiovascular disease risk.

Such examines have generated hundreds of media reports that exaggerate their findings, and omit key details and caveats. Crucially, most recent research has use much higher levels of flavanols than are available in commercial snack products. For instance, the blood pressure examine involved participants getting an average of 670 mg of flavanols. Person would need to ingest about 12 standard 100 g bars of dark chocolate or about 50 of milk chocolate per day to get that much. The European Food Safety Authority has approved one rather modest chocolate-related health claim- that some specially processed dark chocolate, cocoa extracts and drinks containing 200 mg of flavanols” contribute to normal blood circulation” by helping to maintain blood vessel elasticity.

Prof Marion Nestle, a nutritional scientist at New York University, uses the word “nutrifluff” to describe ” sensational research findings about a single food or nutrient based on one, usually highly preliminary, study “. She points out that most surveys on chocolate and health get industry fund, but journalists generally fail to highlight this.” Industry-funded research tends to set up questions that will give them desirable results, and tends to be interpreted in ways that are beneficial to their interests ,” she says.

Research has repeatedly shown that when food companies are paying, they are more likely to get helpful outcomes. US researchers who reviewed 206 examines about soft drink, juice and milk, for example, found that those receiving industry fund were six times more likely to produce favourable or neutral findings than those that did not. Most nutrition scientists who accept fund from industry are in a state of denial, according to Nestle, whose book Unsavory Truth: How Food Companies Skew the Science of What We Eat is due to be published in October.” The researchers involved feel it doesn’t affect the integrity and quality of their work ,” she says.” But research on narcotic industry funding shows the influence is generally unconscious, unintentional and unrecognised .”

The public are also misinformed into believing chocolate is healthy through what scientists refer to as the” file drawer effect “. Two of the aforementioned surveys- those on blood pressure and markers of cardiovascular health- are meta-analyses, entailing they pool the results of previously published research. The problem is that science publications, like the popular media, are more likely to publish findings that suggest chocolate is healthy than those that conclude it is not affected, which skews meta-analyses.” It’s really hard to publish something that doesn’t find anything ,” says Dr Duane Mellor, a nutritionist at Coventry University who has analyzed cocoa and health.” There’s a bias in the under-reporting of negative outcomes .”

Then there’s the problem that, unlike in medication trials, those taking part in chocolate studies often know whether they are being given chocolate or a placebo. Most people have positive expectations about chocolate because they like it. They are therefore primed, through the conditioning consequence- famously described by the Russian physiologist Ivan Pavlov- to answer positively. They may, for example, become more relaxed, boosting different levels of endorphins and neurotransmitters, and triggering short-term physiological benefits.

” The responses of analyse participants can be affected by their beliefs and presumptions about chocolate ,” says Mellor.” Research has also observed people who volunteer for surveys are more likely to be affected by their beliefs about an intervention than the population as a whole .”

Many of the studies that involve people being given chocolate and tracking their health over hour are short and have small numbers of participants. This adds to the difficulties nutritional scientists have in separating out the effects of eating one food or nutrient from the rest of their diet and other variables and interactions within the body.

So when and why did chocolate companies become so keen on using science as a marketing tool? The answer varies depending on whom you ask.

During the 1990 s, scientists became interested in the French paradox- the now discredited observation that heart disease rates were low in France despite their own nationals diet high in saturated fats. One proposed explain was relatively high consumption of flavanols, a group of compounds found in red wine, tea and cocoa which, at high doses, had been linked to the prevention of cellular injury. US researchers caused a stir when from around the turn of the century they concluded that Kuna people off the coast of Panama had low blood pressure and rates of cardiovascular disease since they are drank more than five cups of flavanol-rich chocolate per day.

This undoubtedly stimulated chocolate industry research. However in 2000, a Channel 4 documentary reported on the use of child labour and bondage in cocoa production operations in Ghana and Ivory Coast- the source of most of the world’s chocolate. This triggered a wave of media reports and negative publicity.

Some say the industry poured fund into science at this time to divert attention away from west Africa.” Endeavors by many of the large chocolate companies to demonstrate health effects started side by side with the outcry over the use of child labour and slavery ,” says Michael Coe, a retired anthropologist formerly of Yale University, co-author of The True History of Chocolate .” Some of it was legitimate science, but it was stimulated, at least in part, by the need to say something positive about chocolate .”

Industry figures strenuously disagree.” There was no connection between those two things ,” says Matthias Berninger, vice-president for public affairs at Mars, Inc, when asked whether Coe is correct.” The Kuna story sparked a lot of interest. The level of investment and energy and intensity of research was much more driven by that than it was by the idea of creating a halo around chocolate .”

Critics have accused Mars in particular of using nutritional science to cast its products in a good sunlight. Through its scientific arm, Mars Symbioscience, it has published more than 140 peer-reviewed scientific papers on cocoa flavanols and health since 2005.

The family-owned company has traditionally remained tight-lipped about its involvement in cocoa research. However, last month it published its policies on conducting and funding research. Asked whether it had previously been involved in using research to suggest chocolate was healthy, Berninger says:” I do believe that that was so tempting, Mars couldn’t resist it. If you look back 20 years, there was this idea that this could create huge opportunities for us .”

But he says this changed long ago.” As a marketing strategy, we have not engaged in that for more than a decade .” In 2007, the European Union tightened regulations on nutrition and health claims. Meanwhile, research was inducing it increasingly clear that health benefits claims for commercial darknes chocolate products were unrealistic because of their low flavanol content.

Yet campaigners highlight how chocolate companies, including Mars, have opposed public health regulations that might undermine their profits employing third party. US public health lawyer Michele Simon made hard-hitting reports in 2013 and 2015, documenting how the Academy of Nutrition and Dietetics( AND) and the American Society of Nutrition( ASN ), were receiving big sponsorship fees from major food industry companies. In 2014, the ASN had gone in to bat on behalf of the members of its corporate backers, including Coca-Cola, Mars and McDonald’s, against a US government plan for added sugar content to be included on food labels, and questioning the evidence on their negative health effects. A year earlier, the AND stated its support for a” total diet approach”, and opposition to the” overly simplistic” the categories of specific foods as good or bad.” It’s about co-opting health organisations, and buying legitimacy among professionals and members of the public ,” says Andy Bellatti, co-founder of US-based Dietitians for Professional Integrity.

Chocolate manufacturers have also utilized the classic corporate strategy of using third-party lobbyists to fabricate artificial scientific disagreement. Science is, by its nature, about evidence-based likelihoods not absolute certainties. The exaggeration of uncertainty was perfected by the tobacco companies in the 1950 s, and later copied by the asbestos and oil industries. Chocolate makers have done this through lobbying groups such as the Washington-based International Life Sciences Institute( ILSI ), which campaigned against added sugar labelling in the US, and resisted the World Health Organisation’s 2015 advice that less than 10% of daily energy uptake should come from free sugars- those added to food and drinkings and resulting naturally in honey and fruit juice.

Criticisms of these tactics seem to be reaching home. Mars transgressed ranks with fellow chocolate-making ILSI members including Nestle, Hershey and Mondelez, which owns Cadbury, in 2016 when it denounced a paper funded by the group questioning research linking sugar consumption and poor health, and related health advice. Last month Mars announced it was leaving ILSI.

Mars’s Berninger agrees that the chocolate industry could do more to avoid the spread of health myths.” Chocolate is a treat you should enjoy occasionally and in small portions , not a health food ,” he says.” Did we say that loud enough over the last 10 years? I would say no .”

Public health campaigners welcome Mars’s new posture. Some see it as a genuine attempt to do the right thing, while others highlight how big food companies are seeking to reposition themselves in the face of growing environmental and health concerns. Whatever the motivation, the gulf between the chocolate industry and its critics seems to be narrowing.

Children hoping to celebrate Easter in the traditional chocolatey style on 1 April will be reassured to hear the two sides also agree on another aspect of the debate.” While chocolate is probably not healthy, it’s also not harmful when enjoyed in sensible quantities ,” says Mellor.” Chocolate is candy, adds Nestle.” As part of a reasonable diet, it’s fine in moderation .”

You can say anything with figures …

The role of the media in helping chocolate makers exploit our failure to grasp the complexities of nutrition science was laid bare in a 2015 expose. German television journalists set up a three-week “study” in which they asked one group of volunteers to follow a low-carb diet, another to do likewise but add a daily chocolate bar, a third to induce no change to their diet. Both low-carb groups lost an average of 5lb, but the chocolate group lost weight faster. By measuring 18 different things in a small number of people, the spoofers made it likely they would find “statistically significant” but fake benefits of eating chocolate.

The ” peer-reviewed ” International Repository of Internal Medicine agreed to publish a hurriedly written newspaper within 24 hours of receiving it- for a fee of EUR6 00. John Bohannon, a Harvard University biologist and science journalist in on the hoax, put together a press release. Within days narratives had been published in more than 20 countries. The Mail Online , Daily Express , Daily Star and Bild were among those that fell for it.

” I was just really ashamed for my colleagues ,” says Bohannon.” These are people who regurgitate whole chunks of press releases and almost never call on outside sources. In my volume, that’s not even journalism. It’s just an extension of PR .”
