Soybean oil consumption leads to weight gain and fatty liver in mice

A new study suggests diets high in soybean oil can cause rapid weight gain, worsen fatty liver, and impair glucose tolerance in mice. This effect is linked to oxylipins, molecules produced when polyunsaturated fatty acids like linoleic acid in soybean oil are oxidized. Other oils did not produce similar results. Soybean oil is a common ingredient in processed foods, and researchers believe excessive intake may exceed the body's metabolic capacity, increasing fat accumulation risk.
