Navigating the oil aisle at the supermarket can be a headache-inducing task. Between olive, coconut, canola, and vegetable oil, it can be tough to discern the healthiest option, but a new study has just made your decision a bit easier. According to research published in the journal PLoS One, there's one oil that doesn't belong in your pantry: soybean oil.
Researchers from the University of California fed mice a series of diets containing 40% fat, Prevention reports. The first group was fed fat from coconut oil, while the second group was given soybean oil, which contains unsaturated fat. The team also fed mice two altered versions of the diets containing fructose.
They discovered that the mice who ate a diet containing soybean oil gained the most weight—a whopping 25% more than those who had coconut oil. Compared to those who had fructose in their diet, they also had fattier livers and more insulin resistance, which are both signs of diabetes and metabolic syndrome. Prevention goes so far as to call this ingredient "worse than sugar."
Eradicating soybean oil from your diet and pantry might be easier said than done. The product is a common cooking oil and ingredient in packaged foods. It's the main ingredient in vegetable oil and can be found in bread crumbs, cereals, crackers, imitation dairy foods, infant formula, and more. Instead, add these healthier coconut oil products below to your pantry.
