Cate Shanahan discusses the detrimental health effects of vegetable oils, which she refers to as the "hateful eight": corn, canola, cottonseed, soy, sunflower, safflower, rice bran, and grapeseed oil. These oils are prevalent in processed foods and restaurant dishes, often replacing healthier fats like butter and olive oil. Shanahan highlights that these oils undergo harsh processing, leading to toxic lipid oxidation products that contribute to various health issues, particularly in children.
She cites a toxicologist's claim that consuming fries cooked in vegetable oil can be as harmful as smoking 20 cigarettes, emphasizing the oxidative stress these oils cause in the body. Shanahan explains that oxidative stress is a root cause of many chronic diseases, including Alzheimer's, cancer, and diabetes. She argues that the American Heart Association's promotion of these oils has led to widespread health problems, as they are often found in common foods like mayonnaise, dressings, and fried items.
Shanahan stresses the importance of avoiding these oils and suggests that most of the harmful effects come from processed foods rather than home cooking. She encourages individuals to read ingredient labels and be cautious when dining out, as many restaurants use these oils to cut costs. She believes that the majority of health issues stem from oxidative stress caused by these oils, which deplete the body’s antioxidants and lead to cellular damage.
In her book, *Dark Calories*, she argues that even those warning about seed oils may underestimate their dangers. She calls for a return to whole foods and traditional cooking methods, advocating for a diet rich in healthy fats and nutrients while minimizing processed foods. Shanahan concludes that understanding the impact of vegetable oils on health is crucial for improving overall well-being.
