Many persons have food allergy but are not aware.
‘gas’ ‘flatulency’ ‘acidity’ ‘post food distention of abdomen’, indigestion, constipation, frequently loose motions or loosely formed motions, alternate tight and loose motions, skin rash, swelling in body off & on without diagnosis, irritability are the common symptoms of food allergy. Gluten allergy, Nuts Allergy, Pea nut allergy, Egg Allergy and sea food allergy are well known. Some time it could be fatal. Even most of doctors do not understand food allergy.
In openion of Dr S Z Jafrey; Every person should get Food Allergy Test to know what not to eat. Rather just asking a doctor about sour things and fatty things, food avoidance improve your health, immunity and quality of life.
