High-fat oil and low-paid farmers: the cost of our coconut craze

High-fat oil and low-paid farmers: the cost of our coconut craze

Canary Wharf in London on a Thursday lunchtime, and platoons of well-groomed office workers descend into a warren of underground malls in search of lunch: something healthy, natural and delicious - a little edible holiday from urban desk life. All the big chains are here to tempt the 100,000 ravenous workers, who needn't step outside all day: from Eat, Leon and Pret a Manger to Wagamama, Waitrose and Marks & Spencer. The longest queue is in the vast Waitrose, snaking past fridge after fridge of hermetically sealed, ready-to-eat food. Step a little closer and look at that food, and a trend quickly emerges: at Pret a Manger, you can wash your avocado wrap down with "naturally rehydrating" coconut water, then grab a pot of dairy-free coconut yoghurt with mango for afters. You might have already had the coconut porridge for breakfast, and if that wasn't coconutty enough for you, the top four items on the "Barista Specials" board are - drum roll - coconut-milk coffees. At Eat, it's a mango-and-coconut-milk chia pot; at the Virgin Active cafe, a coconut granola with "pina colada" topping. Waitrose has more than 145 coconut-containing products (although, yes, that does include some toiletries), Morrisons sells 213 and Tesco no fewer than 394. In the UK, coconut water - an acquired taste - was predicted as a "bizarre" trend back in 2010. Yet, seven years later, the market for all things coconut is still expanding. April saw Pret a Manger report record profits - and cite coconut as its most popular new ingredient. Coconut has, of course, been a much-loved staple of cuisines around the world since time immemorial, but, according to the UN's Food and Agriculture Organisation (FAO), global demand is growing at 10% a year. The global market for coconut water hit $2.2bn in 2016. Coconut's myriad uses scratch a number of gastronomic itches, being acceptable to vegans, the lactose-intolerant and those who "avoid dairy" as a lifestyle choice. It provides a rich milk substitute, and its sweet-smelling oil is big with dairy-free baking fans; coconut flesh can be dried and ground down to a gluten-free flour (the Nourished Kitchen food blog extols its high fibre and protein counts but doesn't mention the 14% fat and 18% sugar); coconut water is sold in gyms as electrolyte-rich, post-workout hydration - a natural sports drink. All these products offer the tempting transparency of being free from perceived nasties (AKA synthetic chemicals). Chopped from palm trees in tropical paradises and shipped directly to the expensive aisles of health-food shops, coconuts are catnip to lifestyle bloggers. The coconut's reputation as a health food, however, is controversial, and riddled with false advertising, lawsuits and the misappropriation of scientific research. Things recently came to a head in the US, when, last month, the American Heart Association issued a report that warned consumers off coconut oil because of its absurdly high saturated fat content - higher, at 82%, it pointed out, than the amount in beef dripping (50%) or butter (63%). This has whipped the wellness industry into a defensive lather, and the ensuing tussle between science and believers has, inevitably, been referred to by some media outlets as "coconutgate". Researching the nutritional benefits of coconut reveals a vocal subculture of health-panacea enthusiasts. There are books produced by reputable publishing houses with titles such as The Coconut Miracle and The Goodness of Coconuts, along with numerous websites that will tell you coconuts can stimulate fat-burning, repair damage from degenerative brain disease, shrink tumours, make your hair bigger, hydrate you better than water, boost your immune system, combat ageing and ward off bacterial, viral and yeast infections. The humble coconut has acquired the aspirational sheen of celebrity endorsement. We can't entirely blame Gwyneth Paltrow and her lifestyle empire, Goop, for popularising coconut as a superfood, but, unsurprisingly, she can take some credit. In a 2013 interview, she announced that she uses coconut oil "a lot" in cooking and on her face ("it's supposed to clear up your skin", she had read on the internet). She detoxifies her mouth with it, too, swilling it around in an "ancient" process called oil pulling. A kit, which includes a tiny bamboo spoon and peppermint lip balm, can be purchased via the Goop shop for $36. However, Paltrow is not the only celebrity to profit from coconuts. Launched in the US in 2004, and the UK in 2010, Vita Coco is the big kahuna of coconut water. Not only is Rihanna a front-woman for the brand, but Madonna, Matthew McConaughey, Demi Moore and Anthony Kiedis of the Red Hot Chili Peppers all shrewdly invested in the company. A $1bn sale to PepsiCo is rumoured to be on the cards. With its claims of being "super-hydrating" and "nutrient-packed" (later dropped, after consumers sued them for being misleading), and its sexy "Born in Brazil" tagline (also later dropped), the brand steamrollered into retail refrigerators the world over. It is even selling coconuts back to the Philippines, the world's biggest exporter, on the basis that cartons are hygienic (except when a squid-like foreign body gets inside) and way more convenient than climbing trees while holding a machete. The drink, consumers have been told, is rich in potassium, an electrolyte our bodies need in order to recover from dehydration. This happens to be meaningless, though, without a decent whack of sodium, says Linia Patel, a dietitian and British Dietetic Association spokeswoman. "Without the key electrolyte, sodium, the drink doesn't optimally hydrate," she says. "Sure, it's a type of fluid to take on board, but if you're doing high-end performance sport, a sports drink, which may have more sugar but more sodium and less potassium, would probably rehydrate you better." Besides, she points out, most mortals don't exercise enough to need special drinks. Even if you've been for a really intense half-hour run? "No," she laughs. "Sadly not. Drink water." This is not to say that unadulterated coconut water isn't a mildly nutritious sweet drink to enjoy as an occasional treat - but the smallest carton (330ml) of Vita Coco will set you back 59 calories - and watch out for other brands adding sugar. Jack Fitzgerald, a consumer-protection lawyer in San Diego, sees health claims for coconut water as small-fry in the public-health stakes. "We do have a lawsuit against Viva Labs right now," he says, about their coconut oil, which, as well as being touted as extra-virgin, 100% raw, organic and cold-pressed, has been marketed as a healthy alternative to butter. But they're not the only targets. Other companies currently the subject of lawsuits include Nutiva, the largest manufacturer of coconut oil in the US, as well as purveyors such as Nature's Way, Costco and Better Body. They all sell "coconut oils where the labels have health and wellness claims". In general, when his team has sent letters to manufacturers, they have changed their labels pretty quickly, "although some continue to litigate over it", he says. Out of the hundreds of coconut oil producers, "most of them don't make health claims. The ones who make health claims happen to be some of the bestselling coconut oils. That's not a coincidence." No one is denying that coconut oil contains more saturated fat than butter and lard. Where the coconut contingent has gained leverage is in the murky, emerging landscape of good fats and bad fats. "The thing in coconut that makes it different," says Patel, "are medium chain triglycerides (MCTs), which are a type of fatty acids. They get absorbed differently, so the body can use them immediately." There is a popular theory that the MCTs in coconut oil promote fat-burning - the same pseudoscience behind the soundly rubbished Bulletproof Coffee fad, in which butter and coconut oil are added to coffee, promising clearheadedness and weight loss. The evidence cited is a small human study from 2003 in which people fed a diet rich in MCTs shed some body fat. One of these MCTs is lauric acid, which coconut fetishists are keen to point out is abundant in breast milk. Because what could be more naturally nourishing than breast milk (which evolved to fuel the extremely rapid growth that is unique to babies)? Even the study's author, Marie-Pierre St-Onge, of Columbia University, has distanced her work from the coconut claims. "I think the data that we've shown with medium chain fatty acids have been extrapolated very liberally," she has said. She wasn't even studying coconut oil, which is only partly made up of MCTs, whereas she fed people solely MCTs. "You can't compare a study that uses just MCTs with coconut oil," says Patel. "All the [health] claims are marketing hype based on fairy stories," says Laurence Eyres, of the New Zealand Institute of Chemistry, who reviewed the literature on the effects of coconut oil on humans last year. "Their advice is scientifically incorrect and unethical." In his paper, he wrote: "The evidence of an association between coconut consumption and risk factors for heart disease is mostly of very poor quality." Nevertheless, he suggests that when compared with other plant oils, coconut "raises total cholesterol although not as much as butter does". So manufacturers aren't fibbing about it being better than butter? According to Jim Mann, a professor in Human Nutrition and Medicine at the University of Otago, who authored the leading study on this, "Coconut oil is indeed as high in saturated fat as butter, but there are four major saturated fatty acids which contribute to total saturated fat. Coconut oil is relatively high in lauric acid. Butter is relatively low in this fatty acid and high in both myristic and palmitic acids. Lauric acid is associated with a better lipid profile than myristic and palmitic, so butter has an overall worse profile than coconut oil on this important predictor of coronary heart disease." Crucially, though, he still does not encourage the use of coconut oil. "Although it may be preferable to butter, there is evidence that total saturated fat (regardless of which saturated fatty acid is involved) is associated with adverse health outcomes - heart disease being the main culprit, but there's also some evidence in relation to diabetes."
