The gallbladder concentrates and stores bile as a pear-shaped sac which it can release to help digestion after a fatty meal.
An elimination diet is used to test for food allergies. In an elimination diet food items are eliminated one by one to test for adverse reactions. Suspected food items are completely removed from the diet for a period of time and the patient is monitored for a resolution of symptoms. Diagnosis made with the help of an elimination diet helps in identifying the causes and mechanisms of food allergy. When following an elimination diet, take care to ensure an adequate supply of vitamins and proteins through alternate food substances. An elimination diet is based on trial-and-error but is useful in cases with vague symptoms of allergy.
