Let's Talk Nutrition With Nico Episode 8: How Social Media Is Changing Healthcare and Supplement Education

The eighth episode of "Let's Talk Nutrition with Nico," a collaborative video series between Lana Pine of The Educated Patient and Nicholas Saraceno of Nutritional Outlook, looks at a New York Times investigation into AI-generated wellness influencers, new consumer survey data on where Americans actually get nutrition advice, and a peer-reviewed model describing how misleading health content on social media translates into real-world risky behavior.

Saraceno also discusses how supplement brands and practitioners are responding—including the idea of pairing up with registered dietitians, physicians, and other credentialed experts—and revisits an industry perspective on misinformation examples like berberine being marketed as "nature's Ozempic."

A transcript of Pine's and Saraceno's conversation can be found below.

Lana Pine: I'm Lana Pine, senior editor of The Educated Patient, and welcome to episode 8 of "Let's Talk Nutrition with Nico." I'm joined as always by Nico Saraceno, senior editor of NO. Nico, good to see you again.

Nicholas Saraceno: Good to see you too, Lana. Today's topic is one I think your audience is going to relate to just as much as mine, maybe more. We're talking about how social media is changing where people get their health and supplement information, and honestly, how much of it holds up.

Pine: This is a conversation I have with patients constantly. Someone comes in having already decided what's wrong with them and what supplement they need, based on a video they saw the night before.

Saraceno: That's exactly the behavior the data is starting to catch up with. There was a national survey¹ out recently from the Academy of Nutrition and Dietetics that put some real numbers on it. Forty-six percent of people say they've acted on nutrition advice from a social media influencer, a third have used something like ChatGPT to build themselves a nutrition or weight-loss plan, and 56% just rely on their own online research to make decisions.

Pine: And how many of those people are actually talking to a dietitian or a doctor first?

Saraceno: That's the part that stood out to me most. Forty-four percent said they have no interest in working with a registered dietitian at all, and when you dig into why, it's not just cost, though a third cited that. A good chunk said they simply didn't think they needed one, or didn't know how to find one in the first place.

Pine: So it's not just competition from influencers, it's a real access and awareness gap on the professional side.

Saraceno: Right, and the Academy's own framing was that clickbait headlines and viral challenges are feeding a confusion problem, not just a trust problem. Eight in 10 Americans in that survey said they struggle to tell nutrition fact from fiction. Interestingly, even with AI tools, 43% said they don't trust AI for nutrition guidance, despite a third of people already using it that way.

Pine: People don't trust it, but they're using it anyway.

Saraceno: Which tells you it's often more about convenience than confidence. And that tension gets a lot more serious when you get into where some of this content actually comes from. There was a New York Times investigation² published this summer that I think is worth walking through, because it's not just influencers anymore, it's fabricated ones.

Pine: Fabricated how?

Saraceno: The Times looked at hundreds of social media ads and found AI-generated videos of fake doctors and fake traditional medicine practitioners, complete with fabricated credentials, staged in office settings designed to look legitimate. Some used the same visual tricks repeatedly, American flags, suburban backdrops, to build trust fast.

Pine: That's genuinely unsettling from a patient-safety standpoint.

Saraceno: It gets worse. One case they documented involved a 71-year-old woman who bought a moringa supplement after seeing one of these Facebook ads. That product ended up linked to a multi-state salmonella outbreak that the FDA and CDC announced earlier this year. And separately, some of these ads were making outright illegal disease claims, like herbal supplements outperforming prescription medication for kidney disease, the kind of claim that would never make it onto television but barely gets touched online.

Pine: What did the industry side say about that? I imagine that's not a great look for legitimate supplement companies either.

Saraceno: It's not, and the Council for Responsible Nutrition pushed back pretty directly.³ Their statement was that fraudulent marketing and fake health experts aren't features of the dietary supplement industry, they're clear violations of existing law. Their argument was that AI didn't invent this problem, it just made it faster and cheaper to pull off, and they're calling for stronger FDA and FTC enforcement, along with things like a mandatory FDA product registry.

Pine: Is there any research on what this kind of exposure actually does to someone, beyond one bad purchase?

Saraceno: There is, and this is where it gets interesting from a behavioral standpoint. A 2026 study⁴ modeled exactly that pathway, using data from 482 social media users. The short version is exposure to misleading wellness content increases what they called psychological vulnerability, which then makes people more likely to internalize false claims, which then predicts actual risky health behavior. It's a chain, not a single moment. And notably, they found women showed a stronger behavioral response to those internalized false beliefs than men did.

Pine: That framing is useful, honestly. It's not that one video convinces someone of something false, it's cumulative.

Saraceno: Exactly, which is part of why a single fact-check rarely undoes the damage. So that's the misinformation side. But I don't want this episode to be all doom and gloom, because there's a real counter-trend happening too, which is credentialed practitioners building their own presence to compete for that same attention.

Pine: I've noticed that. More dietitians and physicians treating content creation as part of the job now.

Saraceno: Right, there have been brands that have launched programs that pair them with a roster of credentialed experts, from a nutritionist, a functional medicine physician, a dermatologist, an integrative health physician, to a sports dietitian, putting out monthly social content.

Pine: So brands are trying to fight the trust battle by putting real credentials front and center.

Saraceno: That's the bet, yes. Whether it actually shifts behavior the way an anonymous, algorithm-favored account can is a separate question, credentialed content doesn't always win the engagement game, but it's a sign that companies are taking the credibility gap seriously rather than just leaving the space to whoever's loudest.

Pine: Where does that leave manufacturers who aren't running programs like that? What's the practical takeaway?

Saraceno: There was a piece we ran a while back from Dr. Amanda Frick⁵ on the brand side that I think still holds up here. Her argument was that manufacturers have a direct role in fixing this, not just regulators, and she pointed to specific examples, berberine getting marketed online as "nature's Ozempic" despite working nothing like the actual drug, or taurine getting sold as a longevity supplement off the back of preliminary animal data with no human evidence behind it yet.

Pine: Those are exactly the kind of claims that spread fast because they sound simple.

Saraceno: Right, and her point was that education, transparency, and actually testing raw materials rigorously are supposed to be baseline expectations, not differentiators. But when misinformation is what's filling the vacuum, doing those things quietly isn't enough anymore. Brands and practitioners kind of have to compete for the same attention the bad actors are already getting.

Pine: That's a good note to end on. It's not really an influencer problem or an AI problem in isolation, it's a whole information ecosystem that patients and consumers are trying to navigate largely on their own.

Saraceno: Couldn't agree more. I'll drop links to everything we covered today in the video description. Thanks for having me, Lana.

Pine: Thanks, Nico. See you next time!
