A sthma is a chronic inflammatory disease of the airways associated with hyperresponsiveness and reversible bronchoconstriction with variable clinical course and outcome. Globally, about 339 million people are estimated to be affected by asthma [1], with considerable higher morbidity and mortality in low-middle-income countries [2]. In the majority of cases, the onset is in early childhood and approximately 6% of children in India suffer from asthma [1]. The treatment of childhood asthma by standard regimen is constantly evolving, yet due to diverse etiological factors, prevention continues to remain elusive. The disease process manifests as the interplay between various environmental triggers, genetic susceptibility and host response.The role of dietary factors in the precipitation of asthma has gained much attention from the researchers in the past decade [3,4]. Decreased antioxidant intake, changing composition of polyunsaturated fatty acids, and altered gut microbiota are some of the postulated mechanisms resulting in either upregulation of the pro-inflammatory pathways or downregulation of the anti-inflammatory markers [5]. Studies have focused on the association of individual nutrients with asthma (i.e., Vitamin D3 and selenium) [6,7], evaluation of the role of specific foods (i.e., fish) [8], and identification of the protective effects of a dietary pattern (i.e., the Mediterranean diet) [9]. The impact of nutrients in asthma has been studied right from the prenatal period to adolescence and adulthood, although with inconsistent results [5,10]. Dietary habits and food groups beneficial to one population may not be exactly applicable to the other simply due to the difference in the ethnic, genetic, and regional differences.In general, children's dietary habits depend on the availability, accessibility, local customs, parental beliefs, food fads, and peer group influences, especially in adolescence. Hence, this study was designed to focus on the common food practices in a semiurban region of South India and to evaluate the role of various dietary factors in precipitating childhood asthma.
