Hannah D. Holscher

About

Dr. Hannah Holscher is the Director of the Nutrition and Human Microbiome Laboratory and a Professor of Nutrition in the Department of Food Science and Human Nutrition at the University of Illinois. Her laboratory focuses on understanding the interplay of diet, the microbiome, and health and disease. As the lab director, she leads a team that includes graduate students, research staff, and undergraduate members, all working collaboratively to explore the complex relationships between nutrition and the human microbiome. Dr. Holscher's work aims to elucidate how dietary factors influence the microbiome and, in turn, impact human health outcomes.

• The International Scientific Association for Probiotics and Prebiotics (ISAPP) consensus statement on the definition and scope of synbiotics

  Nature Reviews Gastroenterology & Hepatology · 2020 · 2005 citations

  In 2019, the International Scientific Association for Probiotics and Prebiotics (ISAPP) convened a panel of experts specializing in nutrition, microbial physiology, gastroenterology, paediatrics, food science and microbiology to review the definition and scope of postbiotics. The term 'postbiotics' is increasingly found in the scientific literature and on commercial products, yet is inconsistently used and lacks a clear definition. The purpose of this panel was to consider the scientific, commer…

• The Prebiotic Potential of Inulin-Type Fructans: A Systematic Review

  Advances in Nutrition · 2021 · 255 citations

  Inulin-type fructans (ITF), including short-chain fructooligosaccharides (scFOS), oligofructose, and inulin, are commonly used fibers that are widely regarded as prebiotic for their ability to be selectively utilized by the intestinal microbiota to confer a health benefit. However, to our knowledge the literature thus far lacks a thorough discussion of the evidence from human clinical trials for the prebiotic effect of ITF, including beneficial effects on intestinal microbiota composition and in…

• Avocado Consumption Alters Gastrointestinal Bacteria Abundance and Microbial Metabolite Concentrations among Adults with Overweight or Obesity: A Randomized Controlled Trial

  Journal of Nutrition · 2020 · 78 citations

  BACKGROUND: Avocados are rich in dietary fiber and monounsaturated fatty acids (MUFAs), nutrients that have been independently connected to metabolic health benefits and the gastrointestinal microbiota. OBJECTIVES: We aimed to evaluate the impact of avocado consumption on the gastrointestinal microbiota and microbial metabolites, secondary outcomes of the Persea americana for Total Health (PATH) study, and conduct exploratory analyses to assess relations between the fecal microbiota, fecal metab…

• Higher protein intake during resistance training does not potentiate strength, but modulates gut microbiota, in middle-aged adults: a randomized control trial

  AJP Endocrinology and Metabolism · 2021 · 34 citations

  Our research evaluates the efficacy of higher in comparison with moderate animal-based protein intake on resistance exercise training-induced muscle strength, clinical biomarkers, and gut microbiota in middle-aged adults through a dietary counseling-controlled intervention. Higher protein intake did not potentiate training adaptations, nor did the intervention effect disease biomarkers. Both diet and exercise modified gut microbiota composition. Collectively, moderate amounts of high-quality, an…
