In a talk titled “Coconut oil and other nutritional errors,” Karin Michels, who is an adjunct professor of epidemiology at Harvard T.H. Chan School of Public Health, says coconut oil is not healthy, calling it “poison” at least three times in the widely-circulated video.
“I can only warn you urgently about coconut oil,” she says. “This is one of the worst foods you can eat.”
Michels is also the director of the Institute for Prevention and Tumor Epidemiology at the University of Freiburg in Germany.
Comments for the video, which posted in July, have been disabled.
While coconut oil has been advertised as a health food of sorts, nutrition experts say there is little evidence to back that claim. Alice Lichtenstein, a Tufts University professor of nutrition science and policy who is vice chair of the federal government’s dietary guidelines advisory committee, recently told The New York Times 「there’s virtually no data to support the hype.」
It’s not “poison,” but American Heart Association data has shown more than 80 percent of the fat in coconut oil is saturated — far beyond butter (63 percent), beef fat (50 percent) and pork lard (39 percent).
Donald Hensrud, medical director of the Mayo Clinic Healthy Living Program, told USA TODAY last year that “there’s a disconnect between people’s general beliefs and what the data actually show.” He recommends instead using oils high in monounsaturated fats (including olive oil and avocado oil) and those high in polyunsaturated fats (such as canola oil).
简单点说：市场上很多宣传的椰子油功效并未数据支持，而椰子油的饱和脂肪含量极高 — 高达 80%，相比之下猪油的饱和脂肪含量只有 39% — 因此有营养学专家，比如 Mayo Clinic Healthy Living Program 的老大 Donald Hensrud，建议大家还是食用橄榄油（olive oil）、酪梨油（牛油果油、 avocado oil）、芥花油（canola oil）等非饱和脂肪油类。
