This is specifically a study for sucralose (e.g. Splenda). Most diet drinks in the US and other countries are aspartame (e.g. Equal).
I see sucralose in a lot of processed foods, especially ones trying to pretend to be healthy. It's a shame that it's hard to find unsweetened sliced bread in some stores.
American bread has sugar because it's cheap and Americans like it.
It's worth maybe pointing out that this study was based on sucralose, just because it seems this sweetener is worth tracking separately in general. I don't really consume things with artificial sweeteners but sucralose is starting to become a concern of mine (eg for my daughter).
Still think it's worth keeping track of artificial sweeteners as they're not all the same in their effects.

So I think that this brain reward system still applies to anything that tricks your palate to think something is sweet.
