AI-Summary
What this Trial Is About
Randomized controlled trial of soluble fiber (Fruitafit Inulin). Participants will complete an ASA 24 dietary recall questionnaire to access their fiber intake. If eligible for the study, participants will be supplemented to their target fiber dosage with either soluble fiber (Fruitafit Inulin) or placebo. Collection of blood serum, fecal samples, and nasal wash will aid in analyzing the microbes present in one's gut and how fiber and diet may impact it. Thus, allowing researchers to better understand the pathways that may connect diet and asthma and if it is possible to improve asthma by altering one's diet.
