But I loved it. Also this has Shrimp removed, because it was on the OG chart due to an error and this is an updated version.

Grains are "better" than I would have expected.
I so wish we could get actual wheat grains at the supermarket, possibly bio. Instead whole cereals are mostly sold as animal feed (so with fewer safety standards). It's bs. Same goes for soy beans! They give 'em out to farmers for a lot less than a 1€/kg as animal feed, but I have to order them online? While every corner shop has tofu, soy milk, etc.. come on 😅
