"I can only warn you urgently about coconut oil", she says.
Its superfood status had already come under scrutiny past year when the American Heart Association (AHA) updated its guidelines, recommending people avoid the saturated fatty acids found in coconut oil. If a fat is saturated, that means it is molecularly structured so that each carbon atom in the fatty acid chain is linked to its maximum number of hydrogen atoms.
But experts can't seem to agree on how much saturated fat people should consume in a healthy diet, or if it should be avoided altogether.
Last year, the AHA updated its guidelines, to recommend people avoid the saturated fatty acids found in coconut oil.
"We want to set the record straight on why well-conducted scientific research overwhelmingly supports limiting saturated fat in the diet to prevent diseases of the heart and blood vessels", lead author Dr.
While scientists never reached any conclusions that should have elevated coconut to its extreme superfood status, what they found wasn't all bad - and it certainly wasn't poison. The rats did indeed stop eating and lost weight, but the injection also slowed the animals' heart rates and lowered their basal body temperature, a toxic effect - though fortunately not one particularly relevant to eating coconut products, given that the study was not about diet or even coconut oil. "It is one of the worst foods you can eat".
"We are well and sufficiently supplied", she said, according to a translation of her German address. Each tablespoon of coconut oil provides 130 calories.
Coconut oil is is packed with phytochemicals that have beneficial antioxidant, anti-inflammatory properties.
Unfortunately, if you've been swapping butter out for it to keep you healthy during breakfast it turns out coconut oil is about a shocking 86 percent saturated fat - about a third more than butter, which is 52 percent. 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).
So what's the actual verdict on coconut oil?
