10 gross ingredients you didn't know were in your food

Since the horsemeat scandal, more of us than ever before are holding a microscope up to what we eat. But no matter how many labels you read, you could still be consuming things you'd rather put on your "do not eat" list. From human hair in our bread to fish bladder in our beer, there are a lot of additives and food processing techniques that employ ingredients and chemicals few would classify as "appetising". It's a reminder, frankly, that non-processed foods are your best bet.
