Toxic Seed Oils Turn French Fries Toxic, Sadly

French fries are a beloved indulgence, but the toxic seed oils used to fry them can transform this treat into a health hazard. You may have seen this photo of cigarettes in a French fry cup before. It’s an AI-generated image. But it’s not just a made-up meme. It started circulating shortly after I was interviewed for this movie. During the interview, I made the rather shocking comparison between cigarettes and French fries. That comes from a study called: Toxic Lipid Oxidation Product (LOP) Generation in Culinary Frying Oils (CFOs) During High-Temperature Frying Practices: Passage into Fried Foods. In it,…

And unless we’ve gone for days without eating, normal hunger is a light stomach-grumbling sensation that goes away when we ignore it. Hypoglycemia makes us hangry. Hangry on on the other hand is hard to ignore.…

Low Smoke Point Olive Oil on High Heat–Is It Safe?

Olive Oil has a Low Smoke Point. Can you still cook with it? We’ve all heard a thousand times high smoke point oils like soy and canola are the oils of choice for cooking–especially high-heat cooking. This is a particular concern for professional chefs who typically cook with temperatures far higher than those used by a home cook. If the oils aren’t smoking that must mean, the thinking goes, that they are chemically stable. No smoke, no free radicals, no toxins. No problems. But I want you to set aside, for a moment, everything you’ve been told about smoke point…
