Cyanide is "natural". Not everything "natural" is good for you. I'm all for alternatives, although as with any other thing, they need to study them to make sure they're safe. Like aspartame, which is one of the most studied substances on earth. It's safe. And it's a fantastic tool to have - saying this as a diabetic, but artificial sweetners gives us the ability to make tasty foods that save calories/carbs, which is something most people can use.

So I don't know about ChoViva in specific, but if there's an alternative to cocoa that doesn't rely on slave labour and isn't harmful… I'm all for it.
