Create ration packs for food intolerances so more people can join the military

I was in the British Army for 7 months before getting medically discharged due to an anti-immune disease called Coeliac. I made it past the entry requirements but fell ill due to the food served in the army canteen. Instead of helping me though the rest of my training they discharged me. If there was food available for me to eat I would have been able to carry on the rest of my training. If they can cater to Halal, vegetarian why not more options. This would open the gate to more soldiers.
