Polyunsaturated fats are highly unstable and are readily oxidized to form toxic compounds that are implicated in most of our modern diseases. Vegetable" oils were introduced in 1910. Since then heart disease has increased 5,820%. And with the increase in consumption of vegetable oils, lung cancer deaths have increased dramatically as well. This is due to the highly reactive nature of polyunsaturated fats. The risk of prostate cancer increases 35% following just one portion of fried food per week Eating a single meal containing vegetable oils induces an inflammatory response resulting in injury to the arterial wall, which is the precursor to cardiovascular disease. Yet these oils, are ubiquitous, and touted as beneficial to your health. This manuscript is a result of two years of exhaustive research, based entirely on peer reviewed literature. The book is unique in that there is no other of its kind in print. It links many of the so-called "western" diseases to the oxidation products found in vegetable oils. Chapters include: The Elegant Complexity of Fats, History of Seed Oils, Lipid Peroxidation, Arteriosclerosis and Cardiovascular Disease, Polyunsaturated Fats and Cancer, Immune Suppression and Inflammation, Obesity and Diabetes, Diet Modification, Dysbiosis, Neurological Implications, lipofuscin and aging.
