Poonamjot Deol, Ph.D., a cell biologist at the University of California said “Mice who ate the soybean oil diet without fructose gained the most weight, 9 percent more than the fructose eating mice and a whopping 25 percent more than the mice who got their fat from coconut oil. Compared to their fructose eating counterparts, the mice on the soybean oil diet also had fattier livers and more insulin resistance, both signs of impending diabetes and metabolic syndrome.”
We’ve actually tested corn oil, and we found that it was also causing more obesity than coconut oil, but not as much as soybean oil. We haven’t tested canola yet.
Soybean oil is supposed to be healthy. It is everywhere. A full half of all the vegetable oil produced in the world is soybean oil. And since it’s cheap, the stuff is used in endless packaged foods. It’s also a favorite at restaurants.
Deol said “It’s so prevalent in our food system. If something says vegetable oil, it’s most likely soybean oil, or soybean oil is a component.”
