8. Beer

Sometimes there’s nothing better than a tall frosty glass of beer. There are all different types and textures of beer, but the beautiful see-though amber versions are hiding a yucky secret.

As if the fermentation process isn’t gross enough when you really think about it, beer includes an ingredient called isinglass to help make the product more clear and bright. Isinglass comes from fish – it’s a type of gelatin made from dried fish bladders.
