Official title
Benzoic Acid in Beverages: Establishing a Link Between Urinary Metabolites, Metabolic Dysregulation and Weight Loss Failure
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The benzoic acid derivatives sodium and potassium benzoate are preservatives that are commonly added to food and beverages to inhibit microbial growth and prevent spoilage. In the US the major source of benzoate intake is beverages. Studies have shown that piglets or chicks fed low levels of benzoic acid have greater feed efficiency and gain more weight than control fed animals. It has also been shown that benzoic acid inhibits the release of a key metabolic hormone, leptin, from isolated adipocytes (fat cells). Inadequate leptin levels result in increased appetite, decreased metabolic rate, weight gain, insulin resistance and increased diabetes risk. The primary aim of the proposed research is to directly determine if benzoate consumption in human volunteers results in lower levels of leptin, decreased metabolic rate and increased insulin resistance. If so this would implicate benzoic acid as an obesogen and would help inform more effective approaches to obesity prevention and treatment. A secondary aim of the study is to establish a connection between benzoate exposure and biomarkers in urine that can be used to help treat obese patients.
