Excessive intake of polyunsaturated fats, particularly linoleic acid, is associated with increased cancer risk and mortality.

“there's countless negative implications we even have one trial with extra polyunsaturated stedy saturated fat and the heart disease went down a little mortality but the overall mortality didn't change and that team I think it was the veteran study a year late or quietly published a paper indicating that the cancer mortality had gone up and that's why it canceled out the heart disease reduction so there's a lot of connections and an animal experiments relating to the oxidizing of these puffers in the 90s that clearly showed an impact on carcinogenesis and mammary carcinogenesis”
