15. Newcastle Brown Ale

As the bottle tells us, Newcastle Brown Ale is imported from England, and it has a rich, alluring color to it. However, this color is a sign of the horrible ingredients that have been put into the beer. This beer has been found to have caramel coloring in it. Class 3 and 4 caramel coloring, which is made from ammonia, is a carcinogen—or in other words, something that can cause cancer or foster cancerous cells. Since alcohol is a carcinogen in and of itself, adding more to the mix is not a good idea, especially if you’re one to indulge in multiple brews over the course of an afternoon.
