Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study tests the effectiveness of dietary interventions that have the possibility to improve markers of gut health and improve general well-being. This study will allow healthcare professionals to learn how dietary interventions involving fasting can affect health. Food is increasingly recognized as a core component of preventive and ameliorative health care. Juice fasting has quickly become one of the most popular self-prescribed dietary interventions in the United States. A wide variety of juice fasts are available in the popular market; a popular variation is the three-day juice fast. The purpose of this study is to assess the effects of a three-day juice fast on certain markers of age-related disease and bio-markers of longevity. In particular, this study will assess certain epigenetic markers, which measure how the environment (including diet) can change the way that genes are expressed without changing the genes themselves. The study will also assess the microbiome, and inflammatory and glycemic markers.
