I honestly don’t have a problem with it under the right circumstances. i.e. free to eat them or not. I wouldn’t mind a bar made from that powder. I would concern myself with what else was in it to make it taste good. I used to be a long distance bike rider. I ate some healthy, but terrible tasting and terrible texture foods in those days. This could be a good dietary supplement.
Currently I eat a can of sardines a day for health reasons. It’s also quite tasty.
