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]

Diet can influence asthma risk; higher consumption of fruits, vegetables, and dairy is associated with a reduced risk, and a shift from a proinflammatory diet to a less inflammatory one may also help. Additionally, early-life antibiotic use may alter the microbiome and increase asthma risk later on.
