Descriptive Information
Brief Title  ICMJE Bioavailability and Metabolism of Avenanthramide: a Novel Oat Phytochemical
Official Title  ICMJE Bioavailability and Metabolism of Avenanthramide: a Novel Oat Phytochemical
Brief Summary The purpose of the study is to examine whether orally ingested oat avenanthramides (AVA) in oat flour cookies are bioavailable in humans by measuring plasma and urine concentrations of AVAs and their potential metabolites after ingestion. The blood and urine concentrations will be quantified at several different time points after the oat flour cookies are consumed to characterize the "concentration-time profile".

Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Basic Science
Condition  ICMJE
  • Bioavailability
  • Metabolism
  • Avenanthramides
Intervention  ICMJE Other: Avenanthramides
AVAs are a group of diphenolic acids that are found only in oats (Avena sativa). In this study, each dietary group of subjects will receive three cookies made with oat flour containing high-AVA (H-AVA, 229.56 mg/kg) and low-AVA (L-AVA, 32.69 mg/kg).
Study Arms  ICMJE
  • Placebo Comparator: Low-AVA oat flour cookies
    Three low-AVA oat flour cookies
    Intervention: Other: Avenanthramides
  • Experimental: High-AVA oat flour cookies
    Three high-AVA cookies
    Intervention: Other: Avenanthramides
