Diet rich in corn oil leads to lethargy and pre-diabetic symptoms

North Americans typically get 7 per cent of their energy from Omega-6 polyunsaturated fatty acids, about seven times the nutritional requirement.

However UBC biologist Sanjoy Ghosh found that mice fed a high-fat diet rich in corn oil- a major source of Omega 6 – developed lethargy and pre-diabetic symptoms in less than two months. Mice who ate olive oil remained healthy.

“Corn oil-fed mice became pre-diabetic within six weeks,” Ghosh said.
