After eating coliflower sometimes i get gas and stomach cramps, burping is this gastritis, if so what should i do i love vegatables?

Maybe intolerance: Seemingly your belly is just not agreeing with cauliflower. Most people have some degree of disagreement with certain foods. What you described is not gastritis. If you have excessive gas/belching with this, gas-x may help. Also, eat a bit less of this to see if it helps. Fortunately, there are plenty of other veggies around--i like them too. Veggies up to a healthier you! good luck.
