Exposure to refined carbohydrates has been found to be associated with disorders such as increased blood pressure, retinopathy, adipose tissue inflammation, glucose intolerance, type 2 diabetes mellitus, poor metabolic profile, esophageal adenocarcinoma, and small intestine, prostate, pleural, and pancreatic cancers. Additionally, recent studies have demonstrated that ingestion of refined carbohydrates is related to secretion of cytokines and chemokines. However, to our knowledge, there is still no data on the relationship between refined carbohydrate consumption and allergic disorders ranging from bronchopulmonary to skin diseases. Therefore, the purpose of this review was to evaluate whether consumption of refined carbohydrates plays a role in allergic diseases. Crown Copyright (C) 2014 Published by Elsevier Inc.
