The coconut has attained superfood status.
Lured by endorsements from celebrities, supermodels and even Kourtney Kardashian, consumers are clamoring for coconut oil, coconut water, coconut milk and coconut-infused cocktails. They’re pouring coconut into coffee, spreading it on toast, swishing it like mouthwash and gulping it down after hot-yoga classes, enticed by the promise that coconut can banish belly fat, boost heart health and even stave off the effects of Alzheimer’s disease.
And since coconut lends a nutty sweetness, a crunchy texture and an aroma that evokes the tropics, no wonder it’s been embraced as a healthful indulgence.
But does coconut offer any real health benefits?
Researchers, dietitians and doctors say that coconut’s properties are promising, but the data just isn’t sufficient to start recommending daily doses.
The science we have is interesting, but it’s too early to deem this as the next superfood and start pouring it on everything, says Kristin Kirkpatrick, a registered dietitian and the manager of wellness nutrition services for the Cleveland Clinic Wellness Institute. We just don’t have enough evidence.
Even coconut connoisseurs urge people to incorporate it into an overall healthy lifestyle.
Like any superfood, it can improve health, but only when it’s supported by a healthy diet and exercise, says Healthy Grocery Girl Megan Roosevelt of Portland, Oregon, a registered dietitian and the author of Superfoods, for Life: Coconut.
Most of the excitement revolves around coconut’s reputation as a weight-loss tool. Coconut oil contains large amounts of medium-chain triglycerides, which are used for fuel more quickly than the long-chain triglycerides found in most animal-based products such as meats and dairy. LCTs linger longer in the bloodstream and are more readily stored as fat.
Because fats high in MCTs are metabolized faster by the liver, coconut oil may have a slight edge over other fats in terms of weight loss. But the research is limited, Kirkpatrick says.
There is a perception that because it’s plant-based, it’s healthier than animals fats. But like animal (fat), it has calories, lots of them, and that makes a big difference in weight loss.
Such studies are too small to justify bold health claims, cautions cardiologist Ashley Simmons, the medical director of the University of Kansas Hospital’s women’s heart program.
I think we need to look at all these studies very cautiously, she says.
To be sure, coconut oil does have some proven benefits. It contains lauric acid, which reduces inflammation associated with acne, and it has been shown to have antimicrobial properties. And there is some evidence that virgin coconut oil contains antioxidants that may play a role in reducing inflammation associated with arthritic conditions.
Coconut oil is a smart substitute for other saturated fats, such as butter and shortening, Simmons says. Those animal-based fats raise LDL (bad) cholesterol. Coconut oil raises HDL (good) cholesterol as well as LDL, so it doesn’t carry the same cardiovascular risk. As a saturated fat, it’s probably better than others, she says. But it’s still a high-calorie, highly saturated fat.
Indeed, coconut’s high proportion of saturated fat – which increases inflammation and risk for cardiovascular disease – gives health experts pause.
Coconut oil has a higher proportion of saturated fat than other plant-based oils. A tablespoon of coconut oil has calorie and fat counts similar to those of olive oil, but 88 percent of the fat in coconut oil is saturated, compared with just 15 percent in olive oil.
The oil also has been hailed for its potential to delay the effects of Alzheimer’s disease.
The coconut craze reaches beyond the kitchen. Some recommend it for oil pulling, an ayurvedic method that has been said to banish migraines, whiten teeth and detox the body. Oil pulling involves swishing oil in the mouth for five to 20 minutes, then spitting it out. The American Dental Association recently warned that oil pulling shouldn’t be substituted for tooth brushing, fluoride use or other oral hygiene measures.
