Boiled vs. Fried Eggs: What Actually Changes Inside Them.

Scientists took two eggs from the same carton, boiled one, fried the other, then measured what was actually inside each one. The protein looked similar, but one thing changed dramatically: a form of damaged cholesterol, barely present in the boiled egg, but much higher in the fried one. In this video, we look at what cooking actually does to an egg: why raw egg protein is only partially digestible, how heat can oxidize cholesterol into compounds called oxysterols, and why the real issue was never frying itself, but heat, yolk, and fat. 🥚 In this video: Same egg, two different outcomes Why raw egg protein isn't fully absorbed Denaturation: how cooking unlocks protein Cholesterol oxidation products (oxysterols) Why boiled eggs stay cleaner The twist: frying isn't automatically bad Why the cooking fat matters just as much The 3-step practical method 🔬 About The Kitchen Lab We take everyday foods and explain, in simple visual stories, what research suggests happens inside your body after you eat them.
