The study is meant to observe the influence of nutrition on nasal and bronchial discomfort in patients with allergy on grass pollen after specific bronchial provocation. Therefore, the investigators will record the patients' nutrition habits and measure the blood level of long chained polyunsaturated fatty-acids.

Condition Intervention
Bronchial Hyperreactivity
Bronchial Asthma
Other: inhalative specific bronchial provocation with grass-pollen
