Let’s Talk Nutrition With Nico: How Social Media Is Reshaping Where People Get Nutrition Advice

On the latest episode of “Let’s Talk Nutrition with Nico,” Nicholas Saraceno, senior editor of Nutritional Outlook, and Lana Pine, senior editor of The Educated Patient, discussed how a national survey from the Academy of Nutrition and Dietetics is putting hard numbers behind a trend clinicians already notice anecdotally. Saraceno said 46% of people report acting on nutrition advice from a social media influencer, about one-third have used artificial intelligence (AI) tools like ChatGPT to build a nutrition or weight loss plan, and 56% rely primarily on their own research.

Meanwhile, 44% of respondents said they have no interest in working with a registered dietitian at all, a gap Saraceno said isn’t purely about cost. While roughly one-third cited financial concerns, many others said they either didn’t think they needed a dietitian or didn’t know how to find one. Saraceno noted that eight in 10 Americans surveyed said they struggle to distinguish nutrition fact from fiction, and that despite growing AI use for guidance, 43% said they don’t actually trust AI-generated nutrition advice, a disconnect between usage and confidence that both hosts flagged as notable.

Fabricated Experts and Real Consequences

The conversation turned to a New York Times investigation, which Saraceno said examined hundreds of social media ads and found AI-generated videos depicting fabricated doctors and traditional medicine practitioners, complete with invented credentials and staged office settings designed to appear legitimate. Saraceno described recurring visual cues, like American flags and suburban backdrops, used across multiple fake accounts to build a sense of trust.

The consequences extend beyond deception alone. Saraceno cited a case involving a 71-year-old woman who purchased a moringa supplement after seeing a targeted Facebook ad; the product was later linked to a multistate salmonella outbreak flagged by the U.S. Food and Drug Administration (FDA) and Centers for Disease Control and Prevention. He also noted that some ads made outright illegal disease claims, including herbal supplements marketed as outperforming prescription medication for kidney disease.

The Council for Responsible Nutrition pushed back against the narrative that this reflects the supplement industry broadly, calling fraudulent marketing and fake health experts clear violations of existing law rather than industry features. The organization argued AI didn’t create the underlying problem but made it cheaper and faster to execute, and called for stronger FDA and Federal Trade Commission enforcement along with a mandatory product registry.

The Behavioral Toll of Misinformation

Saraceno referenced a 2026 behavioral model using data from 482 social media users, which found that exposure to misleading wellness content increases psychological vulnerability, making people more likely to internalize false claims, a pattern that in turn predicts risky health behavior. The study found women showed a stronger behavioral response to internalized false beliefs than men, though Saraceno emphasized the issue affects all demographics. He noted that a single fact-check isn’t sufficient to reverse this kind of cumulative exposure.

A Countertrend: Credentialed Experts Entering the Content Space

Not all the news was discouraging. Saraceno pointed to a growing countertrend of credentialed practitioners, including nutritionists, functional medicine physicians, dermatologists and sports dietitians, building their own social media presence and content programs in partnership with brands. Whether credentialed content can compete with algorithm-favored anonymous accounts on engagement remains uncertain, he said, but the shift signals that companies are taking the credibility gap seriously.

What Manufacturers Can Do

Saraceno referenced prior commentary from Amanda Frick, N.D., LAc, who argued manufacturers bear direct responsibility for addressing misinformation, not just regulators. She pointed to examples like berberine being marketed online as “Nature’s Ozempic” despite working nothing like the drug, and taurine being sold as a longevity supplement based on preliminary animal data. Frick’s broader point, Saraceno said, is that education, transparency and rigorous raw material testing should be baseline expectations for brands, not differentiators, particularly as misinformation continues to fill any vacuum left behind.
