Deep health Thoughts for the day: How bad is the oil you're consuming from your favorite fried foods? And what about Kettle Corn? Yikes!
Deep-frying and reheating cooking oils can create carcinogens, including: Polycyclic aromatic hydrocarbons (PAHs), Aldehydes, Acrylamides, and Acrolein.
When oil is reheated, it produces byproducts that contain PAHs and aldehydes. These byproducts can react with air to create oxidized compounds that may be toxic and carcinogenic. Repeatedly reused oil breaks down triglycerides, which releases acrolein, a toxic chemical with carcinogenic properties.
Cooking fumes also contain over 200 harmful gases, including PAHs and aldehydes, which are known to be carcinogenic, mutagenic, and tumorigenic. Exposure to cooking fumes in a non-ventilated environment has been linked to lung cancer in non-smokers.
Some oils with higher smoke points, like avocado, peanut, or refined olive oil, can be used for sautéing or roasting to reduce the risk of acrylamides. Coconut oil is resistant to oxidation and polymerization, but it has a lower smoke point and is only recommended for one-time shallow frying.
