In the Decade of Nutrition, food must be reconsidered. The main objective of our research was to establish if there are any correlations between ultraprocessed food consumption and increased asthma prevalence or other respiratory outcomes. Meanwhille, it will be an important step to design some lifestyle recommendations with direct benefits for asthma treatment. NOVA system for food classification is a new concept addressing food quality. Ultraprocessed food, made entirely from substances derived from food and additives, that includes other sources of nutrients and energy, is not usually used in culinary preparation. How asthma outcomes are influenced by Western diet that contains a lot of processed food and what benefits could arise from the Mediterranean diet are subjects for interesting studies. Substantial correlations have been established between unhealthy diets, especially Western diet, ultraprocessed foods and food allergies and asthma pathogenesis and control. NOVA clasification of processing foods and dietary inflammatory index are helpful tools in early identifying of correct dietary approach in asthma. More research in nutrition recommendations for asthma patients must be done and practical guidelines in nutritional interventions are future steps.
