The following are some of the ways to get in touch with us. Dr. Andrew Weil, founder of the Andrew Weil Center for Integrative Medicine at the University of Arizona, shared: “A recent study found that a toxin called 4-hydroxy-trans-2-nonenal (HNE) forms when such oils as canola, corn, soybean, and sunflower oils are reheated. Foods containing HNE, a toxin formed by cooking oils, have been shown to increase the risk of cancer and liver disease.
