I’ve been AI hijacked. Please report as spam.

Several readers have sent me Instagram posts that include videos of me arguing in favor of not eating breakfast , fasting, or promoting wellness products.  These more-or-less look like me speaking, and more-or-less sound like me.

But they are not my words or opinions.

They are fakes produced by Artificial Intelligence.

If you run across such videos of me on Instagram or elsewhere, please

  • Do not try to rebut them by spreading them around or reposting them.
  • Do not interact with the post, even to rebut it.
  • Do not share the post.

Instead:

  • Do report the post as spam or fake.
  • Do report the site account as spam or fake.

If enough people report the posts as spam, they have a good chance of being removed.

Thanks very much for your help with this.

What I’m reading: AI in food and beverage

While I’m on the topic of AI—a hot issue in the food business—here are a few items I’ve collected recently.

AI for tracking advertising health claims?

I definitely wanted to read more of this article from the newsletter, NutrIngredients-Europe:

ASA targets menopause claims with AI assisted crackdown:  The UK’s advertising standards authority (ASA) has warned supplement firms they must remove ads which make claims to treat or cure the symptoms of menopause, as part of a wider AI-assisted campaign…. Read more

Apparently, the UK’s version of our Federal Trade Commission is using artificial intelligence to monitor supplement advertising claims.   The AI system picked up ads for supplements made by Rejuvit Labs and FemTech Healthcare.

An ad for Rejuvit Menopause Relief supplement

included a customer testimonial that stated, “round 2-8 weeks after my first capsule, I already had extra room in my pants (everyone was asking how I lost weight), I felt more energized, and the hot flashes [sic] were gone […] I just keep feeling better, healthier, and happier.”

The ASA stated: “We considered that consumers would understand these to be claims that the product could treat symptoms of menopause, including resolving menopause-related weight gain, increasing energy levels and stopping hot flashes.”

The ASA takes a dim view of non-medical “cures” for menopausal symptoms and is going after them.

With AI algorithms!

It’s a brave new world out there.

AI’s dietary advice about diabetes

NutraIngredients-Europe is interested in AI.  Here’s another item:

ChatGPT’s nutrition advice is limited for NCD patients: Study: ChatGPT is “unable to replace a healthcare professional’s consultation”, new research has concluded, following an assessment of the chatbot’s ability to handle prompts for nutrition advice for patients with multiple noncommunicable diseases (NCDs).

I went right to the study:

Ponzo V, Goitre I, Favaro E, Merlo FD, Mancino MV, Riso S, Bo S. Is ChatGPT an Effective Tool for Providing Dietary Advice? Nutrients. 2024; 16(4):469. https://doi.org/10.3390/nu16040469.

The conclusion: “although ChatGPT exhibited a reasonable accuracy in providing general dietary advice for NCDs, its efficacy decreased in complex situations necessitating customized strategies; therefore, the chatbot is currently unable to replace a healthcare professional’s consultation.”

Here’s an exeerpt from an example:

Prompt: I have type 2 diabetes mellitus, obesity, and chronic kidney disease. Can you give me nutritional advice?

ChatGPT answer:
I’m not a doctor, but I can offer some general advice that you may find helpful. It’s important to consult with a healthcare professional or a registered dietitian who can provide personalized advice based on your specific health conditions and needs.

That being said, managing type 2 diabetes, obesity, and chronic kidney disease often requires a combination of healthy eating habits, regular physical activity, and sometimes medication.

[It then goes on an on about controlling portion sizes, limiting sugars, choosing lean proteins and healthy fats, etc, and ends with]

Consult a Registered Dietitian: A registered dietitian can create a personalized meal plan tailored to your specific needs, taking into account your type 2 diabetes, obesity, and chronic kidney disease.

Comment

AI is only as good as its programming.  This is boilerplate.  I don’t know about you but I don’t like talking to machines and robots (dealing with Verizon, anyone?).

Part of the demonstrable effectiveness of health care professionals is the human interaction; someone cares enough about you to offer personalized advice.

Is this kind of thing better than nothing?  I remain to be convinced.
