Jacques Izard portrait

As the health status of the population is getting more complex, the Izard laboratory focuses on the interaction of our microbiome with diet and how this interaction impacts wellness. We use culture-dependent and culture-independent methods to understand the impact of the digestive tract bacteria in health and disease such as cancer. The multi-disciplinary approach aims to obtain a greater understanding of our microbiome function to empower everyone to nurture a supportive microbiome. Our participation in the Nebraska Food for Health Center includes the facilitation of clinical studies centered on food, diet, microbiome and host phenotypes.

Jacques Izard, Ph.D. has been involved in basic science studies focusing on bacteria, biofilms as well as in cohort studies. Those cohort studies includes the Human Microbiome Project (HMP; this project recruited few hundred individuals lacking pro-inflammatory condition to observe the microbiome associated with health), the Health Professionals Follow-Up Study (HPFS; with over 50,000 enrolled volunteers, the purpose is to evaluate hypotheses relating to nutritional factors on the incidence of serious illnesses, such as cancer), and the European Prospective Investigation into Cancer and Nutrition (EPIC; more than half a million participants recruited in a study designed to investigate the relationships between diet, nutritional status, lifestyle and environmental factors, and the incidence of cancer and other chronic diseases).
