That depends. Iced coffee on its own, is literally cold coffee. There is much debate as to what health benefits drinking coffee has, so it's difficult to say whether coffee is bad for you. Plus, "health" is of course very subjective. It's only when you start adding in all sorts of tasty additions, then you can start to see why some would question. In a nutshell, any of those fancy drinks you buy at your local coffee shop...probably not good for you. Loads of added sugar, fat, and it's more of those things than it is actual coffee. When you customize it to your liking at home, you can definitely make it a healthier version, turning something that is bad for you into something that could be quite good for you!
