When the already used oil is heated again, it let out a higher concentration of varied toxic chemicals like Aldehydes that are linked with multiple health glitches like heart-related ailments, cognitive problems like dementia, Alzheimer’s, and Parkinson’s disease. Likewise, another poisonous substance that is released when oil is re-heated is 4-hydroxy-trans-2-nominal (HNE) which is poisonous and quite toxic to the body and can hamper bodily functions of DNA, RNA, and proteins.

2. Paves the way for LDL (bad) cholesterol levels

3. Gives you acidity and burning sensations

Reusing cooking oil leads to a poisonous process known as rancidity. After a little exposure to moisture, air or light, oils go through incomplete or complete oxidisation and this process is known as rancidity. Each time the oil goes through the heating process, its particles get to modify and affix a bad taste and smell to the oil and the food cooked in it. Consumption of such oil and food can increase the risk of acidity, burning sensation in the stomach, throat problems and many more.

4. Elevate the risk of inflammation and cancer

A carcinogen is a substance that is associated with the formation of cancer in the body. Re-heating cooking oils increases the harmful substances in it like polycyclic aromatic hydrocarbons (PAH) and aldehydes that are linked with high risks of cancer and inflammation in the body. Moreover, if you have been suffering from high inflammation for a longer period of time, then the consumption of bad or reused cooking oil can be the culprit.
