@rey "superfoods" have been a thing for a number of years, it's why you suddenly see a lot of stuff with acai and quinoa and stuff
afawk there's nothing really exceptional, nutritionally, about the foods people make these claims about, other foods are also similarly good for you, but it does mean more variety

@rey oh and kale, kale is another one that has a lot of hype about its nutrition
disclaimer: we haven't looked into any of these specifically, we just know that very commonly these "superfoods" turn out to have a lot of something, yes, but other more common things also have a lot of that same something
