Now, a while back I talked about Skittles not being vegetarian before 2009. Although Mars did manage to rectify this problem and make Skittles vegetarian they did not make the same changes to some of their other products such as M&Ms. M&Ms contain E120 (otherwise known as carmine) which is derived by boiling scale insects. Mars have tried to conceal what it actually is by labelling it 'E120' although it is actually boiled beetles!Photo credits:
