Not sure about spelt. I think it does affect people with celiac to some extent. I've heard emmer takes more elbow grease to grind to flour because the wheat berry is particularly hard. I'm sure it would be equally tasty though. As a heritage grain, though, it might also be more expensive than spelt, like kamut/khorasan.
Sourdough is also a good prep method because the fermentation step enhances mineral availability. Sourdough spelt sounds really yummy, btw.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
