1. Hydrogenated Oils
You might think that oil from vegetables ought to be healthy, but this is another case where processing of natural products makes them dangerous. Oil cannot be extracted from whole vegetables naturally, so they undergo a chemical extraction process.
Then, the oil is colored and the natural scent is removed to make the finished product look appealing. This chemical process is what makes the oil hydrogenated.
It is found in many processed foods, added for texture and to preserve them, but hydrogenated oils affect the cells’ structure and flexibility, upping the chance for cancer to develop.
