On the bread, be careful of an ingredient called "L-cystine". This is in many of the bread products, loaves of bread, wraps, pita pockets, etc. It is a dough conditioner and a non-essential amino acid which comes from pig and human's hair.

It is derived from keratin,  Keratins are a family of fibrous structural proteins; tough and insoluble, they form the hard but un-mineralized structures found in reptiles, birds, amphibians, and mammals. They are rivalled as biological materials in toughness only by chitin.
