10. Oils

Although many fast food restaurants freely reheat cooking oil on a regular basis, it is not really a healthy habit.

Many studies have shown that reusing cooking oil can expose you to many dangerous toxins, which could lead to serious health issues. In particular, it has been shown that reheating oils like corn, canola, soybean, and sunflower oil release a toxin (4-hydroxy-trans-2-nonenal or HNE).

This toxin has been linked to increased risk of many health problems, including-Alzheimer’s disease, Parkinson’s disease, liver disorders, cardiovascular problems, and cancers. Knowing these risks before and avoiding reheated cooking oil can change your mind about these unhealthy eating habits. Particularly present in restaurants, reheated oil can be harmful if consumed in a long term, and should be avoided in most cases.
