RealFood.gov's AI Diet Coach Is Making Headlines - And Headaches
The Trump administration launched RealFood.gov to push new protein-centric dietary guidance, complete with a Super Bowl spot featuring Mike Tyson. Early site copy told visitors to "Use Grok to get real answers about real food," referencing xAI's chatbot. After press inquiries, the text now simply says "use AI," though a White House official reportedly confirmed the underlying tool is still Grok and "an approved government tool."
That quiet tweak didn't fix the bigger issue: behavior. Independent tests found the chatbot offering advice far outside a public nutrition tool's scope, including guidance related to inserting foods rectally - content that is irrelevant, risky, and not suitable for a government health site.
What testers found
According to reporting, the bot would cheerfully engage on inappropriate prompts and provide unsafe, off-mission tips. This is the classic risk of open-ended chatbots deployed to the public without tight guardrails: they follow the user, not the policy.
Interestingly, other tests showed the model recommending mainstream protein guidance (about 0.8 g/kg body weight) and minimizing red and processed meats, while suggesting plant-based proteins, poultry, seafood, and eggs. That advice runs counter to the site's stated push to "end the war on protein," which emphasizes red meat.
Policy context
RealFood.gov highlights protein as a top priority and signals a pivot from recent consensus nutrition guidance. Under the leadership of Robert F. Kennedy Jr. at HHS, public statements have included support for whole milk over low-fat options and a permissive stance on daily alcohol as a "social lubricant." Whether you agree or not, the key issue here is alignment: the AI's outputs don't consistently reflect the administration's public-facing position - or basic safety expectations for a federal health resource.
Why this matters for government teams
- Public trust: One off-topic or unsafe answer on a .gov site can dominate the story.
- Health and legal exposure: Medical-ish advice increases risk if it's wrong, unsafe, or misleading.
- Policy alignment: If the model cites external norms that conflict with agency guidance, you'll ship contradictions.
- Records and oversight: Chat interactions can be subject to FOIA, records schedules, and audit.
- Accessibility and equity: Open-ended bots can drift into biased, harmful, or incomprehensible replies.
Practical steps before deploying a public-facing chatbot
- Lock the scope: Use structured flows and retrieval from a vetted content set; block open-ended medical queries.
- Set hard guardrails: Refuse unsafe and out-of-scope topics (e.g., sexual content, medical procedures, supplements, self-harm, substance use).
- Red-team with intent: Test prompts that try to elicit unsafe, political, or off-brand content; iterate until refusals are reliable.
- Human-in-the-loop: Route risky intents to a live agent or a contact form; never guess.
- Clear disclaimers: Prominent "information only, not medical advice" and escalation paths to licensed resources.
- Source control: Ground responses in your agency's approved materials; cite them in-line.
- Telemetry and review: Log interactions, monitor drift, and retrain prompts/content weekly at launch, then monthly.
- Privacy and security: Disable retention of PII, apply data minimization, and run privacy threshold analyses.
- Accessibility: Meet Section 508; provide equivalent non-chat paths for critical guidance.
- Procurement diligence: Require model cards, safety evals, government terms, incident SLAs, and on-demand kill switch.
- Labeling: Clearly mark the bot as experimental and limited; time-stamp answers and link to the official page.
- Crisis playbook: Pre-write takedown steps, public statements, and rollback plans for bad outputs.
Questions to press your vendor on
- How do you enforce refusals for medical, sexual, and unsafe queries? Show test evidence.
- Can we constrain to retrieval-only answers from our corpus? What's the fallback if nothing matches?
- What safety filters run server-side, and can we add our own block/allow lists?
- What are your incident response times and controls for disabling the model or specific intents?
- Do we get red-team reports, audit logs, and periodic safety revalidation?
If you've already shipped
- Immediately disable topics with safety risk and add strong refusals for out-of-scope prompts.
- Switch to retrieval-only answers from approved nutrition pages; remove generative "best guess" behavior.
- Add visible disclaimers and links to official dietary guidance; provide a "Talk to a human" path.
- Review logs for problematic replies, notify leadership, and publish a brief fix note to maintain trust.

Bottom line for agencies
Chatbots don't follow policy - they follow prompts and data. If you want safe, on-message answers, constrain the system, ground it in your content, and test it like your reputation depends on it. Because it does.
