Brief Summary

Asthma is a common illness among children in the United States. While there are many known causes of asthma, including tobacco smoke, pollen, dust, or other allergens, the exact cause of asthma in some individuals remains unknown. This study will examine the role that specific dietary factors and body mass index (BMI) play in the development of childhood asthma.
