Strengths, Weaknesses, and Reproducibility in Nutritional Randomized Clinical Trials (RTC) and Epidemiological Studies

We invite you to a virtual presentation with a goal to identify and discuss factors that can influence the reproducibility of results between epidemiological studies and nutritional interventions, identify gaps in knowledge, technical hurdles, and develop new approaches for the development of novel nutrition prevention strategies. The speakers’ presentations will be followed by a 30 minute panel discussion.

The webinar will cover:

  1. Potential benefit of nutritional interventions
  2. Reasons for variability in response
  3. Difficulties in reproducibility

Dr. Traber’s lab is currently investigating the assessment of the delivery and function of liposoluble vitamins. For example, the lab is studying vitamin E; its interactions, and mechanisms that might have adverse effects with respect to vitamin K metabolism. They are measuring the absorption, biokinetics, and bioavailability of vitamin E in humans.

The Effect of Prescription Drugs on Nutrients

Dr. Podszun is currently heading the department of Nutritional Sciences and Dietetics at the University of Hohenheim in Germany. She is interested in lipid soluble nutrients, their interactions with prescription drugs, as well as their role in metabolic diseases such as non-alcoholic fatty liver disease.

Diet and Cancer Prevention: Reconciling the Observational and RCT Findings and Moving Towards Precision Nutrition

Dr. Song’s research focuses on nutritional and clinical epidemiology of cancer. Specifically, his work integrates large-scale observational studies with biomarker-based randomized clinical trials to identify novel nutritional and gut microbiota-targeted strategies for cancer prevention and treatment. Currently, Dr. Song is a co-investigator of the Microbiome Among Nurses (Micro-N) Study, a large prospective microbiome study of 20,000 women in the Nurses’ Health Study II.
