Hi, as an almost qualified allergy and nutritional therapist, have to pass the exams next month! Bloating is usually caused by candida in the gut. This is an overgrowth of yeast fungus. Taking probiotic will help a little but you need to kill the candida first and then take probiotic to repopulate the good bacteria. The probiotic has to be a very good one containing lactobaccilli and bifidobacterium at 4 million plus. Bio-acidophulus usually has this amount.The food allergies are caused by a depleted immune system because of the candida.Eating yeast and sugar will make it worse as candida thrives on these. Sugar cravings are candida craving. There are herbal preparations to kill candida but really the best way is to see an allergy therapist to find one that suits you and which foods are affecting you. Once you clear the candida most foods you will be able to eat again. Taking B vitamins will help your energy as candida takes your B vitamins. Good luck.
