Millet
Eat millet and feel better in a minute.
In the early 1300s, this little golden-yellow grain was eaten as polenta and used in bread-making.
It was a favourite among the Germans; so much so that in their mythology the home of Goddess Holden, the protector of fertility, was a mound of millet.
It’s also suitable for young infants and people recovering from an illness, as it’s easy to digest.
As well as coeliacs, since it doesn’t contain gluten. Basically, there’s no reason why you shouldn’t eat it too.
