Summary

Purpose: To compare the change in nasal cell HO-1 expression induced by two different preparations of sulforaphane (SFN)-containing nutritional supplements Participants: Healthy nonsmoking young adults, age 18-35 Procedures (methods): This pilot study will use a randomized crossover design. Subjects will be randomized to receive either the equivalent of 4 ounces/day of fresh broccoli sprouts (FBS) in food and tea, or the equivalent amount as broccoli sprout homogenates (BSH), for 3 consecutive days. Nasal lavage and blood samples will be obtained before, during and after this 3-day period. After at least a 2-week washout interval, the protocol will be repeated with the alternate supplement. The primary analysis will test the hypothesis that broccoli sprouts in food will increase HO-1 expression to a similar degree as the equivalent amount of sprouts in BSH
