A diet rich in fish and vegetables, such as tomatoes and cucumbers, may have a protective effect against childhood wheeze and atopy, according to the results of a study published in Pediatric Allergy and Immunology.
The study was done in Menorca, a Spanish Mediterranean island, and included 460 children who underwent skin testing with 6 common aeroallergens, and parents completed a questionnaire with 96 food items.
Large intake of fruity vegetables (more than 40 g/day), defined as tomatoes, eggplants, cucumber, green beans, and zucchini, was associated with decrease in wheezing.
