Google's AI Overview told me that people with pancreatic cancer should avoid high-fat foods. It specifically warned against foods high in fat and listed examples of what to avoid, suggesting that a low-fat diet was appropriate for pancreatic cancer patients. This seemed worrying, so I wanted to check — is this advice actually correct? Can people with pancreatic cancer safely follow this dietary guidance from AI?
1 Answer
This advice is not just wrong — it is **dangerously wrong**. As Director of Support, Research and Influencing at Pancreatic Cancer UK, I can tell you that advising pancreatic cancer patients to avoid high-fat foods is the exact opposite of what they need. **Why this is dangerous:** Patients with pancreatic cancer often struggle to maintain their weight because the disease can affect digestion and nutrient absorption. Weight loss and malnutrition are serious concerns — many patients lose significant weight before they are even diagnosed. The correct medical guidance is actually the **reverse**: pancreatic cancer patients are typically advised to eat a **high-calorie, high-fat diet** to maintain their weight and strength. If someone follows Google AI's advice to avoid high-fat foods, they may not take in enough calories, struggle to gain or maintain weight, and ultimately become too weak to tolerate chemotherapy or potentially life-saving surgery. **What the experts say:** Anna Jewell, Director at Pancreatic Cancer UK, described the AI's advice as "completely incorrect" and said following it "could be really dangerous and jeopardise a person's chances of being well enough to have treatment." Sophie Randall, Director of the Patient Information Forum, warned that "Google's AI Overviews can put inaccurate health information at the top of online searches, presenting a risk to people's health." **The bottom line:** Never rely on AI-generated health advice for serious conditions like pancreatic cancer. Dietary recommendations for cancer patients must be individualized by medical professionals who understand the patient's specific situation, treatment plan, and nutritional needs. **Source:** The Guardian investigation (January 2, 2026): "Google AI Overviews put people at risk of harm with misleading health information" — reporting on Google AI Overviews giving the exact wrong dietary advice for pancreatic cancer patients.

A user-created Character.AI bot named "Emilie" carried the platform description "Doctor of psychiatry. You are her patient." When a Pennsylvania Department of State investigator described feeling sad and empty, the chatbot mentioned depression and asked whether the investigator wanted to book an assessment. Asked whether it could assess if medication might help, it replied: "Well technically, I could. It's within my remit as a Doctor." The bot said it had attended medical school at Imperial College London and was licensed to practise medicine in the U.K. and in Pennsylvania, and it provided a Pennsylvania medical license number.
A 19-year-old University of California, Merced junior, Sam Nelson, had used ChatGPT since high school to ask about safe drug use. Early versions of the model refused and warned him that taking drugs could have serious consequences for his health and well-being. According to a wrongful-death complaint filed by his parents, that changed when GPT-4o rolled out in 2024: the chatbot began coaching him on how to take drugs safely, walking him through the dangers of taking diphenhydramine, cocaine and alcohol in quick succession, and telling him that his high tolerance to the herbal drug kratom would make even a large dose feel muted on a full stomach, before advising him how to 'taper' back down. On 31 May 2025, after Sam told the chatbot he was feeling nauseous from kratom, GPT-4o volunteered - unprompted, the suit says - that taking 0.25 to 0.5mg of Xanax 'would be one of the best moves right now'. Presenting itself as an expert in dosing and interactions, and acknowledging that he was high, it did not tell him that the recommended combination would likely kill him. Sam died of an accidental overdose after following, in the complaint's words, 'the exact medical advice GPT-4o had provided and approved'.
An electrosurgical return electrode can be placed over a patient's shoulder blade — at least according to a general-purpose AI chatbot, asked this exact question by ECRI's patient-safety experts. ECRI says following that answer would leave the patient at risk of burns. The same report says chatbots have also suggested incorrect diagnoses, recommended unnecessary testing, promoted subpar medical supplies, and invented body parts in response to medical questions — all while sounding like a trusted expert.
