Cough is a common symptom in both children and adults, often indicating a serious underlying condition. Malnutrition is an emerging concern in children with chronic respiratory diseases that require treatment. Several dietary factors, such as maternal and infant diet composition, nutrient status [particularly vitamin D (400 IU) and omega-3 fatty acids], breastfeeding, the use of hydrolysed milk formulae, and the timing of introducing complementary foods, are potential targets for preventing childhood-onset asthma. Diet during the critical periods of pregnancy and lactation can influence the risk of asthma in children. A Mediterranean diet is associated with a reduced risk of asthma or wheezing in children. Vitamins D, A, and E have known immunomodulatory properties.^[1] Dehydration can increase the prevalence and duration of a cough in asthmatic children. Therefore, encouraging adequate daily water intake is essential for managing their cough. The management of cough should prioritise identifying its underlying cause to ensure an accurate diagnosis.^[2]
