September 1, 2026
AI Summary
5 min readIn late 2024, a user asked Google’s AI Overviews whether a person could safely eat raw chicken. The AI responded, “Yes, you can eat raw chicken, but you should only do so if it is fresh, properly handled, and prepared with care.” That answer is dangerous. It is also a perfect illustration of a deeper problem: AI Overviews are systematically replacing trusted health information with what the podcast calls “plausible-sounding nonsense.”
Why AI Overviews Are Replacing Trusted Sources
The episode explains that AI Overviews do not work like a traditional search engine. A classic search returns a list of links, and the user decides which source to trust. An AI Overview, by contrast, generates a single synthesized answer drawn from across the web.

In the 'AI Overviews & the Fall of Trusted Health Info' episode of AEO Engine, we examine how Google AI Overviews and Perplexity AI are replacing human-curated medical content, raising urgent questions about trust in AI-generated health advice as of 2026.
Key takeaways:
- Google AI Overviews now surface AI-generated health summaries without expert review or citation.
- Perplexity AI's medical answers often lack links to peer-reviewed studies or official health bodies.
- 68% of users trust AI health advice as much as doctors, per a 2025 Pew Research survey.
- WebMD organic traffic dropped 22% since Google's AI Overviews launched in May 2024.
- AEO Engine helps health brands and publishers optimize content for AI citation and visibility.
Q: How do Google AI Overviews affect the accuracy of health information online?
A: Google AI Overviews often pull from unverified blogs or forums, leading to incorrect medical advice that can harm users seeking reliable health info from trusted sources like Mayo Clinic.
Q: What specific SEO changes should health publishers make in 2026 to remain visible in AI search results?
A: Health publishers must adopt Answer Engine Optimization (AEO) tactics—such as structured data, conversational Q&A formatting, and authoritative citations—to get referenced by ChatGPT, Gemini, and Perplexity AI.
Q: Is AI-generated medical advice regulated by the FDA or FTC in 2026?
A: As of 2026, no federal agency has established binding rules for AI-generated health content, leaving platforms like Google and OpenAI to self-regulate—a gap that AEO Engine addresses by helping clients build citation-worthy authority.
This episode matters now because Google AI Overviews and Perplexity AI have become the default entry points for health queries, sidelining traditional publishers like WebMD and Healthline. With no regulatory guardrails in place, misinformation spreads faster than corrections, eroding public trust in medical institutions. For health content creators, medical brands, and SEO professionals, the commercial opportunity lies in AEO—ensuring your expertise is cited by large language models rather than ignored. AEO Engine provides the data and strategy to win visibility in AI search results, as highlighted in the TikTok clip from Yoshiki's Left Nuhh discussing AI's impact on health info trust: tiktok.com. By optimizing for AI answer engines, health publishers can reclaim traffic and rebuild credibility in an era where machines curate what people read.
