The 2025 Dietary Guidelines Advisory Committee is composed of 20 nationally recognized nutrition and public health experts appointed by the U.S. Departments of Health and Human Services and Agriculture. All systematic reviews for this committee undergo external peer review coordinated by staff from the National Institutes of Health (NIH). The committee received 9,942 public comments before publishing its Scientific Report on the 2025 dietary guidelines (USDA/HHS, 2024). That is the federal model for what a scientific advisory committee does, and the same governance principle, including independent academic experts and a published peer-reviewed output, is a starting point for evaluating what a "scientific advisory board" means in wellness.
Satya Jonnalagadda, PhD, MBA, RD, Vice President of Scientific & Clinical Affairs at OPTAVIA, says, "There's a real disconnect between what the published science shows and what people find when they search for us online. We have 30+ scientific research studies and analyses and 100+ peer-reviewed scientific presentations and publications. That body of work doesn't show up in a Reddit thread. What we've learned is that the clinical evidence has to be easier to find—and when it is, the conversation changes completely."
