Excerpts:
New UC Riverside research shows soybean oil not only leads to obesity and diabetes, but could also affect neurological conditions like autism, Alzheimer’s disease, anxiety, and depression.
Used for fast food frying, added to packaged foods, and fed to livestock, soybean oil is by far the most widely produced and consumed edible oil in the U.S., according to the U.S. Department of Agriculture [3]. In all likelihood, it is not healthy for humans.
It certainly is not good for mice. The new study, published this month in the journal Endocrinology [4], compared mice fed three different diets high in fat: soybean oil, soybean oil modified to be low in linoleic acid, and coconut oil.
The same UCR research team found in 2015 [5] that soybean oil induces obesity, diabetes, insulin resistance, and fatty liver in mice. Then in a 2017 study [6], the same group learned that if soybean oil is engineered to be low in linoleic acid, it induces less obesity and insulin resistance.
“The dogma is that saturated fat is bad and unsaturated fat is good. Soybean oil is a polyunsaturated fat, but the idea that it’s good for you is just not proven,” Sladek said.
Indeed, coconut oil, which contains saturated fats, produced very few changes in the hypothalamic genes.
“If there’s one message I want people to take away, it’s this: reduce consumption of soybean oil,” Deol said about the most recent study.
