Epidemiologic studies about food allergy and food sensitization in tropical countries. Results and limitations

Abstract

ABSTRACT: The variety of foods and methods of preparation are part of the cultural identity of each population, and thus the main foods that cause symptoms vary among different regions. Due to their increasing frequency, Adverse Reactions to Food (AFR) have been the subject of extensive study, especially in North America and Europe but few studies have been conducted in other areas, especially in populations located in the tropics and subtropics. In this article, we review available information on the epidemiology of food sensitization and food allergies in tropical regions and explore the different epidemiological data considering the major food involved, the underlying immune mechanism and clinical symptoms partners. In addition, we identify the possible limitations and questions that arise from studies conducted in tropical countries, which helps to generate objectives for future research.
