Is coconut oil the good oil?
Move over chia seeds, there's a new 'superfood' in town. But is coconut oil all it's really cracked up to be, or just another fad?
There's nothing new about coconut oil, but the media has been awash with articles recently extolling its virtues, not to mention the tsunami of celebrities who suddenly swear by it. Websites are full of converts who are adding it to smoothies, drizzling it over salads and even downing it by the spoonful in a quest for better health. Some of the (many) claims about coconut oil include that it:
- controls sugar cravings
- controls weight
- eases digestion
- boosts your metabolism.
Coconut oil is also claimed to provide stress relief and boost immunity. One CHOICE staffer was even told recently in a beauty salon that applying virgin coconut oil would help the hair in her eyebrows grow back! But before you head to the health food section of your supermarket for your own jar of miracle oil, CHOICE finds out what the experts have to say about this year's latest food trend.
What is coconut oil?
Coconut oil is extracted from the flesh of the coconut. It has a slight nutty flavour and works well in both savoury and sweet dishes. It's particularly popular in vegan cooking and can replace dairy products to make pastry and creamy desserts. It has a very high smoking point when cooking and has a long shelf life.
Crazy about coconuts
Melbourne-based dietitian Zoe Nicholson, from private consultancy Figureate, says she's seeing an increase in clients who are asking about coconut oil and cooking with it. "Some believe the claims that are being made about weight loss, boosting the immune system and fighting various diseases, and others are using it because everyone is talking about it and shops are selling it as the new best thing."
Dr Kellie Bilinski, an Accredited Practising Dietitian and spokesperson for the Dietitians Association of Australia, says she has seen an increased interest in the use of coconut oil by the public, much of it driven by those following sugar-free and paleo diets.
The healthier oil?
Both our experts warn that although using coconut oil may have a few health benefits, none of the claims above have been properly researched or proven yet.
A healthier alternative
Most plant-based oils are healthy options, and are probably going to be cheaper as well.
- Rice bran oil and peanut oil are great for stir-frying, while extra virgin olive oil is good for cooking on moderate heat and for salad dressings.
- Canola and sunflower oils are also suitable for cooking.
The pros and cons of coconut oil
- Coconut oil does have some antioxidant properties, potentially because of plant nutrients called phenolic compounds.
- It's an unusual blend of short- and medium-chain fatty acids not seen in other saturated fats, which may offer some health benefits. However, research is yet to confirm this.
- Coconut oil can be a part of a healthy diet, but it's not necessary for optimal nutrition. Most plant oils provide health benefits, particularly extra virgin olive oil which has proven health benefits.
- All coconut oil, whether virgin or refined, is high in saturated fat (higher than butter) so it is considered a solid fat. One tablespoon of coconut oil provides 490kJ (117 calories), 13.6g total fat (11.8g saturated fat), no protein or carbohydrates, and only trace amounts of a few nutrients.
- One of the main concerns is the type of fat in coconut oil. The fatty acids found in coconut oil raise LDL (the bad cholesterol) just like other saturated fats, such as butter. And while coconut may also raise HDL cholesterol (the good cholesterol) it doesn't do this as much as unsaturated fats do.
- Although coconut oil doesn't contain cholesterol, it also doesn't stack up against most other plant-based oils. Canola, corn, safflower, sunflower, soybean, flaxseed, grape seed and extra virgin olive oil all contain significantly less saturated fat.
- The fact that coconut oil is so high in saturated fat needs to be considered in the context of a Western diet, which is typically already high. The Cancer Council of Australia recommends reducing or avoiding saturated fats.
- It's expensive! At around twice the price of olive oil, coconut oil hasn't yet been shown to offer health benefits greater than extra virgin olive oil. Extra virgin olive oil has proven heart health benefits, while the evidence for coconut oil is limited.
But they eat it in Asia...
The fact coconut oil is so high in saturated fat needs to be considered in the context of a Western diet, says Nicholson. Although Asian cuisine does use coconut in many forms, it's one of only a few sources of saturated fat. "Traditionally they don't tuck into cheese, butter, chocolate, big steaks, bacon or fast food just to name a few common sources of saturated fat in the Western diet."
How does food become a fad?
Remember when goji berries were going to pump us full of antioxidants? And when a quick shot of wheatgrass was going to replace a whole plateful of green veggies? When it comes to any kind of trend, there is usually a catalyst.
Consumer psychologist and adman Adam Ferrier wrote a PhD on what makes things cool. His number one finding was that it's impossible for something to be cool without cool people using it. Things become cool by their association with people (more so than the other way around).
Anatomy of a trend
Academic and sociologist Henrik Vejlgaard writes in Anatomy of a Trend that trends usually start in major global cities (he cites New York, Los Angeles, Milan, Tokyo and London as examples) and are kicked off by trendsetters. He identifies trendsetters as being a particular personality type who are key influencers in their social groups and are open to change.
The tastes of these key influencers are often picked up quickly in major cities and adopted by groups such as designers, the wealthy and celebrities. The process is then a cycle of observing and copying by the wider population with the help of the media.
And when it comes to extolling the wonders of coconut oil, plenty of cool people are getting in on the act, from Angelina Jolie to popular Australian anti-sugar advocate, blogger and media personality Sarah Wilson. But the oil's most prominent proponent is supermodel Miranda Kerr, who she says she eats it by the spoonful every day, as well as using it in her hair and skincare routine.
Add to that already-potent mix some preliminary studies that show there might be some evidence of benefits (which are often misinterpreted and generalised into pop science), and suddenly coconut oil is being hailed as the next wonder food.
After that, it's not long before the product is trickling down from a global phenomenon to the local supermarket and reaching saturation point.
