What Is a Superfood?

That's a term that's thrown out a lot. But I think a Superfood is any food that's come from a good source where, whoever grew it was paying attention to the soil, and then more than that, not just the raw material, has been prepared in away that enhances and certainly preserves, but perhaps enhances the nutrients in there, like Sauerkraut made from cabbage that came from good soil, that would be a Superfood, or beef stalk made from beef bones where the animal was pastured, that would be a Superfood, super delicious too.
