The headline seems full of good news!
But which sources of monounsaturated fats? Olive oil? Avocado? Sunflower?
Maybe. Maybe not.
You see, although the study compared the effects of 5 different oils on abdominal fat, three were oil blends not especially high in monosaturated fats. Only the two non-blends had a significantly positive effect.
Those who consumed canola or high-oleic canola oils on a daily basis for four weeks lowered their belly fat by 1.6 percent compared to those who consumed a flax/safflower oil blend. Abdominal fat was unchanged by the other two oils….
Aha! Canola oil. Hello, GMO! (More than 90% of all commercially grown rapeseed/canola is genetically modified.)
It will probably surprise exactly no one that this study was funded by the Canola Council of Canada and Dow Agrosciences (along with the Canadian government).
As a PLoS Medicine study once put it:
Industry funding of nutrition-related scientific articles may bias conclusions in favor of sponsors’ products, with potentially significant implications for public health.
Yet another reminder of why it’s good to routinely read beyond the headlines.
