Health Misinformation: How to Evaluate Medical Claims Online

The internet provides more health information than ever, but not all of it is accurate. Knowing how to evaluate medical claims protects you from harmful misinformation. Red flags for unreliable health information include claims of \"miracle cures\" or \"the one thing doctors don\'t want you to know,\" products marketed primarily through testimonials rather than clinical evidence, websites that sell products they promote as treatments, claims not supported by peer-reviewed research, and information contradicting major health organizations (Health Canada, WHO, PHAC). How to evaluate health claims: check the source (government health agencies, university-affiliated medical centres, and major health organizations are generally reliable), look for citations (reputable articles link to peer-reviewed studies), check the date (medical recommendations evolve - look for recently updated content), be wary of absolute language (\"always,\" \"never,\" \"guaranteed\"), and consult your healthcare provider. Reliable Canadian health resources include Health Canada (canada.ca), the Canadian Medical Association, provincial public health units, HealthLink BC (8-1-1), Telehealth Ontario (1-866-797-0000), and university hospital patient education pages. Your physician can help evaluate health claims and recommend evidence-based alternatives. *This article is for informational purposes only.*
