Health literacy in the age of health misinformation

When the clock ticked over into 2025, I had no intention of even considering coming up with New Year’s resolutions that would shape my new year. But with all that is going on in the world, I’ve given myself permission to reconsider and do all I can to stick to it. And I’m encouraging everyone I know to make the same resolution. 

And that resolution is to do a health literacy check-up and to actively pushback against misinformation. There has never been a time when being health literate is more important. I thought that during the COVID years as we received a daily onslaught of misinformation about vaccines, bogus treatments (bleach, anyone?), outright lies (“it’s just a cold”) and conspiracy theories (“BigVax is behind it all”). But how naïve I was. Those days seems like just a warm-up for what is happening today.

I’m in Australia, but I don’t for one moment think we are immune to the madness sweeping the world. But if you are shaking your head and laughing a little when RFK Jr spews his anti-vax, anti-fluoride, anti-science agenda, or Dr Oz uses his latest pseudoscience claim as the foundation for whatever supplement he is selling, you’re not grasping the seriousness of what is going on. Before we Aussies get too smug, we should remember our own backyard isn’t devoid of charlatans, and it’s only a matter of time before someone like Pete Evans is taken seriously in public health discussions. Think I’m over-reacting? He already made a run for the senate. How long before a conservative party sweeps him into their fold?

I think it’s safe to say that we have moved beyond this sort of misinformation being a fringe issue amongst ‘crunchy’ parents, trad wives and ‘wellness’ influencers. And Gwyneth Paltrow.

Health misinformation is deliberate and it’s mainstream, and protecting yourself against it isn’t optional – it’s essential.

Up until now there have been guardrails in place to protect public health. Boards and regulatory agencies have existed to ensure medical safety and provide us with confidence that there are processes in place to determine the safety of drugs, devices, healthcare programs. Guidelines are based on robust and rigorous research and are developed using evidence and expert consensus. (Side bar: Have people with lived experience been involved in these practises? Absolutely not enough. Could this be better? Absolutely yes.) 

Critical thinkers understand that science is not static. We understand that science changes as evidence evolves. We also understand that we don’t have to follow guidelines blindly. We should understand and consider them. And then use them to make informed health choices. I repeatedly say this to anyone who questions off label healthcare (my favourite kind of healthcare!): ‘I understand guidelines and learn the rules so I can break them safely’. That’s what being health literate does – it gives me an understanding of risks and benefits to make decisions about my health and what works best for me. And it gives me confidence to spot and push back on misinformation.

Critical thinkers also know that questioning medical advice is not the same as embracing conspiracy theories. It doesn’t mean throwing the baby out with the bathwater as you hastily reject modern medicine in favour of snake oil salespeople. It certainly doesn’t mean denying the effectiveness of a vaccines. And it doesn’t mean trusting Instagram wellness influencers. 

More than ever, now is the time to do some questioning – to question who is spreading health information and consider their motives. What are they selling? (Case in point: Jessie Inchauspe who offensively calls herself ‘Glucose Goddess’ while selling her ridiculous ‘Anti Spike’ rubbish as she spreads fear about perfectly normal glucose fluctuations in people without diabetes). And a question that right now should be front of everyone’s mind: What power grab is behind the way someone is positioning themselves as an oracle of health information?

This post is about health literacy in general, but because this blog is called ‘Diabetogenic’ and I have diabetes, most people reading will be directly impacted by diabetes. And if there is any silver lining in this shitshow, it’s this: We’ve been dealing with health misinformation about our condition for decades, so in some ways, we’re probably ahead of the curve. We’ve had to wade through the myriad cures and magic therapies, the serums and pseudo-therapies. And the cinnamon – so much cinnamon! We’ve been standing up for science, challenging misinformation, and ensuring that diabetes health therapies are based on evidence, not fairytales. We’ve expected truth in our healthcare. It’s seemed the normal thing to do. Now it feels like a radical act to be a critical thinker. 

We are a crucial point because health is being weaponised more than ever. Someone told me the other day that my lane is diabetes and health, and I should leave politics out of it. It’s laughable (and terrifying) to think that anyone doesn’t understand that health is political. It always has been. And even more so right now. We are seeing in real time political figures (and rich white men who own electric car companies) weaponise health misinformation for their own agendas, and scarily people are listening to them. They are elevating unqualified voices and aligning with conspiracy theorists, giving dangerous misinformation legitimacy. (And if you think that it’s all eerily familiar, you’re right. It’s already happened with climate change.)

Your radical act is to be smarter, to be more critical, to question sources and motives; follow reputable sources, don’t share viral posts before fact checking (Snopes is super useful here). Don’t reject credible advice and information in favour of conspiracy theories. Stack your bookshelves with books by qualified experts (I’d recommend starting with Jen Gunter’s holy trinity – The Vagina Bible, The Menopause Manifest and Blood and Emma Becket’s You Are More Than What You Eat), including lived experience experts who base their healthcare on legitimate evidence. Follow diabetes organisations like Breakthrough T1D (JDRF in Australia) for research updates and community efforts and be smart about which community-based groups you join. If moderators are not calling out health misinformation, I’d be questioning just how the group is contributing to diabetes wellbeing.  

We know knowledge is power. But that knowledge base has to be grounded in fact, not fiction. Health literacy is critical because misinformation isn’t going anywhere, and neither are the people pushing it for profit and power. My resolution is to sharpen my critical thinking skills, ask questions, and refuse to let bad science set us backwards and cast a dark shadow over the health landscape. Who knew something so fundamental could be such a radical act?
