Diet and Asthma

There is much controversy surrounding the role of food in the development and onset of asthma. Foodstuffs which have been cited as triggering asthma attacks include dairy products, food additives such as salt and monosodium glutamate (MSG), eggs, fruit, fish and shellfish, wine, soy, wheat, chocolate and various nuts, seeds and legumes.

There is, however, little evidence to suggest that food elicits an asthmatic response in individuals. Many studies that have identified certain foodstuffs as triggering asthma, have had limitations or flaws in their design, which has lead to difficulties in interpreting and extrapolating their results. As with other food sensitivities, rather than allergies, involving other body systems like the gut and skin, foods naturally containing the compounds salicylates and biogenic amines, when consumed in high enough amounts, may affect the airways.

Many asthma sufferers modify their diet by actively excluding certain foods in an attempt to improve asthma symptoms or control. This can be of a concern when the diet becomes too restrictive or eliminates food groups, as it can lead to sub-optimal intakes of nutrients that are needed as part of a healthy diet.

Currently, there is insufficient evidence to suggest that asthma sufferers should adopt specific eating regimes. Instead, it is recommended that asthma sufferers consume a varied and nutritious diet.
