While processed bread is known to lead to things such as weight gain and diabetes, did you know that it also can contain human hair? L-Cysteine is a derivative of human hair (which is gathered mostly from barber shops and hair salons in China), and it is added to packaged and processed breads to increase the shelf life.
Sure it's disgusting to think about getting diabetes, but that alone doesn't seem to be enough to deter people from consuming it, given the amount of it that is consumed each year. So, next time you eat some bread, just imagine that you're noshing on that hair you found in your salad last week. That hair that most definitely wasn't yours. Enough said.
