Who Are You Getting Your Health Advice From? The Pew Research Answer Will Shock You

So I came across a Pew Research Center report this week titled Moms, Coaches, Doctors, Entrepreneurs: Who Are America’s Health and Wellness Influencers? — and honestly, I had to stop and re-read the headline twice. Because the answer to the question who are you getting health advice from turns out to be… almost everyone except the people who actually went to medical school.

This isn’t just an American story. The same pattern is playing out in the UK, in Brazil, in South Korea, across Southeast Asia. Everywhere people have smartphones and social feeds, health influencers have quietly replaced general practitioners as the first port of call when something feels off.

What the Pew Research Data Actually Found About Who Are You Getting Health Advice From

The Pew study, released this month, looked at who Americans consider credible sources of health and wellness information. The results are not what most of us would hope for. A significant share of adults said they trust wellness coaches and lifestyle influencers for health guidance — even when those influencers have zero clinical training.

Moms with large social followings ranked surprisingly high. So did personal trainers, entrepreneurs selling supplements, and podcast hosts. Actual physicians? They ranked well — but mostly among older adults. Among people under 35, the trust gap between influencers and doctors has narrowed dramatically.

The blurring of entertainment and health expertise is one of the defining public health challenges of this decade. — A concern raised by researchers in the Pew report context, echoed by the WHO misinformation task force.

And here’s the part that shocked me most. This isn’t because people are naive. It’s because accessing a real doctor is genuinely hard in most parts of the world. Average wait times for a GP appointment in the UK are now over three weeks. In rural parts of India and sub-Saharan Africa, there may be no GP within a realistic distance at all. So people go where the information is fast, free, and sounds confident.

Why Confident Wrong Advice Spreads Faster Than Careful Right Advice

I’m not a psychologist, but I’ve read enough about this to understand the core problem. Doctors say things like it depends, we should run some tests, and the evidence is mixed. Influencers say THIS is the reason you’re tired every morning and I cut out this ONE food and everything changed.

Confidence feels like competence. That’s just how human brains are wired — it’s called the fluency effect, and researchers have documented it in dozens of studies. The smoother and more certain a message sounds, the more credible our brains automatically rate it.

So a fitness influencer who posts daily videos confidently recommending a specific supplement stack — even with zero peer-reviewed evidence — will feel more trustworthy to many people than a cautious endocrinologist hedging their language because, well, science is complicated.

The real-world cost of this isn’t abstract. The World Health Organization documented how social media health misinformation contributed to vaccine hesitancy during the 2019 measles outbreaks across Europe and parts of the Pacific. Over 800 deaths were recorded in outbreaks that health officials describe as almost entirely preventable. That number stayed with me.

The Economics Behind Why Health Influencers Are Everywhere Now

Here’s something the Pew report touches on that I think gets underreported. Health content is extraordinarily profitable on social platforms. A post about symptoms, supplements, or what I eat in a day generates massive engagement — because health anxiety is universal and evergreen.

And the supplement industry — worth roughly $177 billion globally as of 2023, according to Grand View Research — runs almost entirely on influencer marketing now. A single mid-tier influencer with 500,000 followers can earn between $5,000 and $25,000 per sponsored post for a supplement brand. You don’t need a medical degree to collect that cheque. You need an audience and a relatable story.

This creates a perverse incentive. The less nuanced and more confident the advice, the more it spreads. The more it spreads, the more valuable the audience. The more valuable the audience, the bigger the brand deals. The person getting advice has no idea there’s a financial engine running underneath it all.

A Simple Mental Filter Anyone Can Use Right Now

I’m not going to tell you to stop using the internet for health questions — that ship has sailed. But there’s a practical checklist I’ve started using after reading through this Pew data, and honestly it takes about 10 seconds:

First — does this person make money if I believe them? If an influencer is selling a supplement, a course, or a coaching program, their advice is not neutral. That’s not automatically wrong, but you should know the incentive exists.

Second — are they citing an actual study, or just personal experience? I tried this and it worked for me is data from a sample size of one. That’s a story, not evidence.

Third — would a doctor have to give this exact same advice for free? Because doctors cannot make their general guidance proprietary. If someone is charging for access to secret health information, that should raise an eyebrow.

Fourth — can I find this claim on a WHO, national health ministry, or peer-reviewed database page? Tools like PubMed are free and publicly accessible. If a health claim has real backing, you can usually trace it there within two minutes.

None of this makes you an expert. But it makes you a harder person to mislead — and right now, according to Pew Research, most of us are pretty easy to mislead.

What Comes Next — And Who Are You Getting Health Advice From in Your Own Life

The Pew report doesn’t suggest influencers are inherently bad actors. Some are genuinely knowledgeable. Some are doing valuable work making health information accessible to communities that have historically been ignored by mainstream medicine. That matters.

But the structural problem — where confidence and charisma outperform credentials and caution in the attention economy — isn’t going to fix itself. Platforms profit from engagement, not accuracy. And engagement goes to the influencer who tells you exactly what’s wrong with you and exactly how to fix it, not the clinician who tells you it’s probably fine but to book a follow-up in three months just in case.

I took the quiz we built for this article myself. I got Curious but Cautious. Which means I’m basically average, which is both reassuring and slightly embarrassing.

At minimum — next time a health tip stops you mid-scroll, give it those four questions before you act on it. Your body deserves a slightly higher bar than a confident voice and a ring light.
