Allergies

“People with nasal allergies or asthma may want to add broccoli sprouts to their diets, if early research findings pan out.
 
In a study of 65 healthy volunteers, researchers found that an oral preparation made from broccoli sprouts trigger an increase in inflammation-fighting enzymes in the upper airways.
The credit appears to go to a compound called sulforaphane, which is found naturally in broccoli and other cruciferous vegetables like Brussels sprouts, cauliflower and cabbage.
Sulforaphane triggers an increase in antioxidant enzymes that help counter cell damage and inflammation brought on by oxidative stress -- from sources like air pollution and environmental allergens.
 
"Based on this study, compounds in broccoli sprouts have a very potent effect in boosting the airway's self-defense system against oxidative stress," explained lead researcher Dr. Marc A. Riedl, an assistant professor at the University of California Los Angeles David Geffen School of Medicine.”
