Effects of Whole Sprouts on Airway Allergic Inflammation
Dietary Interventions and Asthma Treatment: A Pilot Study of the Effects of Whole Sprouts on Airway Allergic Inflammation

The primary objective of this study is to determine if broccoli sprouts (BS) improves airway inflammatory, oxidative stress (OS), and symptoms among asthmatic adults with aeroallergen sensitization.

The study is a double-blind, placebo-controlled, randomized trial to compare BS to placebo in 40 adults with asthma. 40 adults (age 18-50) who meet these eligibility criteria will be randomized to receive either: (a) BS or (b) placebo (alfalfa sprouts). Subjects will eat a sprouts sandwich daily for three days, and then undergo repeat measurement of outcomes.
