Key Takeaways
- A new Pew Research Center report confirms that most people globally are getting health advice from coaches, influencers, and family — not licensed professionals.
- The global health and wellness market is on track to hit $12.9 trillion by 2031, meaning the financial incentive to give unverified health advice has never been higher.
- According to the WHO, roughly 1 in 3 pieces of health content shared on social media contains inaccurate or misleading information.
- There is a simple two-step credibility check you can apply to any health claim you see online — and it takes less than 60 seconds.
- Not all non-doctor health advice is useless — but knowing the difference between legitimate wellness guidance and dangerous misinformation could literally save your life.
I stumbled on the Pew Research Center’s new report this week — the one asking who gives you health advice online — and I genuinely couldn’t put it down. Because the answer is not who most people expect.
Turns out, a huge chunk of the health information circulating globally right now is coming from moms, life coaches, fitness entrepreneurs, and social media personalities. Not doctors. Not researchers. Not licensed specialists. People with great lighting and a supplement brand to promote.
The Pew Report That Nobody Talked About Enough
Published this week, the Pew Research Center survey looked at who Americans identify as trusted health and wellness influencers. But honestly? The findings reflect a pattern that’s completely global — and that’s what makes it so relevant whether you’re in Lagos, London, or Lima.
The report found that coaches and entrepreneurs are now among the most prominent voices shaping how ordinary people think about their bodies, diets, mental health, and medications. Not all of them are wrong. But a significant number have zero formal medical training — and the people following them often have no idea.
Here’s the part that genuinely shocked me: this isn’t just a fringe internet thing. According to a separate Allied Market Research forecast published this month, the global health and wellness market is projected to hit $12.9 trillion by 2031 — growing at nearly 11% annually. That’s a market so massive it makes sense that thousands of people are flooding into it as experts, credentials or not.
When there’s that much money on the table, the incentive to present yourself as a health authority — without actually being one — is enormous.
Why Who Gives You Health Advice Online Actually Matters More Than You Think
You might be thinking: okay, so some wellness influencer recommends a green smoothie. Who cares? But the issue goes a lot deeper than smoothies.
The WHO has flagged multiple times that health misinformation — what they call the infodemic — is a genuine public health crisis. In 2025, a WHO review found that roughly 1 in 3 pieces of health content circulating on major social platforms contained inaccurate, misleading, or potentially dangerous information. That’s not a typo. One. In. Three.
And this content doesn’t just tell you to drink more water. It tells people to stop taking prescribed antidepressants and replace them with adaptogenic herbs. It tells new mothers that vaccines cause specific disorders — claims repeatedly and thoroughly debunked. It tells people that a $79 supplement can reverse insulin resistance.
When the people giving health advice have a financial product tied to that advice, their objectivity is compromised — regardless of whether they mean well. — paraphrased from the NYT’s analysis of the Pew findings, published this week
The problem isn’t that these voices exist. The problem is that most people consuming this content have no easy way to tell the difference between a certified nutritionist and someone who just took a weekend wellness certification course.
The $12.9 Trillion Incentive Problem
Let me put that market number in context. $12.9 trillion is larger than the entire GDP of Japan and Germany combined. It’s the kind of number that attracts serious investment — and unfortunately, serious manipulation.
When a fitness coach on Instagram sells a 6-week gut health programme for €97, and they have 800,000 followers, the math is simple. Even if just 0.5% of followers buy it, that’s 4,000 sales — roughly €388,000 in revenue. From one product launch. From someone who may have never studied biology beyond high school.
I’m not saying all wellness entrepreneurs are frauds. Some are genuinely trained professionals who happen to have a strong social media presence. The issue is that the financial incentive is identical whether you’re qualified or not.
| Source Type | Typical Credentials | Financial Incentive to Sell You Something | Risk Level |
|---|---|---|---|
| Licensed physician or specialist | Medical degree + licensing board | Low | Low |
| Registered dietitian or physiotherapist | Accredited university degree | Medium | Low-Medium |
| Wellness coach / entrepreneur | Variable — often unverified | Very high | Medium-High |
| Social media influencer (fitness/lifestyle) | Often none | Very high | High |

- Los títulos en línea están perdiendo su valor en silencio — y la mayoría de los estudiantes lo descubren demasiado tarde

The Two-Second Credibility Check Who Gives You Health Advice Online
Here’s what I actually started doing after reading the Pew report — and it takes almost no time.
Before I act on any piece of health advice I find online, I ask two questions: First, does this person have a verifiable, publicly listed medical or scientific qualification — something I can actually look up? Not certified wellness coach (those certifications can be bought online in a weekend), but an actual registered licence with a recognised body. Second, are they directly or indirectly selling something connected to this advice?
If the answer to question one is I can’t find it and the answer to question two is yes — I treat the advice as interesting, not actionable. I might look it up on the WHO site or a national health authority, but I don’t change anything about my actual health habits based on it.
That’s it. Two questions. Sounds obvious, but honestly? Most people — myself included before this week — don’t consistently apply it.

What You Should Actually Do With This Information
The Pew report doesn't say wellness influencers are all dangerous. Some are genuinely helpful for motivation, general lifestyle tips, and making health topics feel accessible. The problem emerges specifically when they cross into clinical territory.
