How could diet affect asthma?

There are several noteworthy connections between diet and asthma. Consumption of fruit-and-vegetable and dairy have all been correlated with a reduced risk of asthma.^[1] Additionally, switching from a proinflammatory diet (such as the Western diet) to a less inflammatory diet (such as the mediterranean-diet) may reduce the risk of asthma.^[2] Finally, there is evidence that alterations to the microbiome (e.g., by antibiotic use early in life) may increase the risk of asthma later in life.^[3]
