Good evening, in the meantime I would like to wish your little girl a quick recovery. The disease certainly stimulates inflammatory states in the intestine and sometimes also in the kidneys, so it is very important that her daughter follows a diet that goes as far as possible to anti-inflammatory the organism. Surely with a personalized program I would be more helpful but, in the meantime, I can advise you to encourage the child to eat green and raw vegetables before each meal, especially celery and fennel . the advice is to eliminate all industrial foods that contain artificial preservatives and dyes and reduce sugars in the diet.
