@drwilliamli: 🌿 Seed oils are not automatically harmful. But under certain conditions, they can form harmful compounds. And that's what you need to know. 🔬 The polyunsaturated omega-6 fats found in many seed oils are more susceptible to oxidation when exposed to very high heat. ⚠️ When these oils are repeatedly heated—such as in commercial deep fryers—they produce increasing amounts of compounds called aldehydes. Some aldehydes have been shown to damage cells and tissues, particularly with repeated exposure. 🌿 The oil itself isn't the problem. Repeated high heat and reuse are what can turn it into something harmful.
