You know your favorite perfume is a combination of so many ingredients, but do you know it may also contain castoreum?

Beer is among the many things containing animal products. Guinness is one great example, as it contains Isinglass, a chemical you usually find in fish bladders.

You may be aware of how many calories are there in ice cream, but you may not know that ice cream, candy, and other red foods may contain a powder called carmine, which is obtained from red cochineal beetles.
