Most food content on the internet is opinion. Some of it is opinion dressed as nutrition advice, which is a different and more consequential thing. Diana Savani’s account, eatingwithadietitian, sits on the other side of that line, and the line is the point of this profile.
Savani is a registered and licensed dietitian based in New England. She earned a bachelor’s degree in nutrition from Keene State College, completed a dietetic internship through Iowa State University and became a dietitian in 2012. Alongside the account, she owns a nutrition and wellness practice, has taught weekly wellness classes for 11- to 18-year-olds at the Floating Hospital for Children at Tufts Medical Center, and has run free nutrition education inside Hannaford supermarkets in Massachusetts through recipe demonstrations, classes and community events. She publishes recipes and food finds across Instagram, TikTok and her own site.
That biography is not decoration. It is the asset, and it is why she can do things the other creators in our series of food maker and creator profiles cannot.

What a registered dietitian can say that a food creator cannot
“Registered dietitian” is a protected, credentialed title with an accredited degree, a supervised internship, a national registration exam and continuing education behind it. “Nutritionist” is not protected in most places, and “wellness creator” is not protected anywhere.
The practical difference shows up in what each person can responsibly assert.
An untrained food creator can say what they eat, how they cook, what they like and how something made them feel. That is lived experience and it is entirely legitimate.
A registered dietitian can go further: interpret nutrition science, translate a label into what it means for a particular eater, advise on substitutions for a medical condition, and say whether a claim a brand is making holds up. She is also bound by a professional code and a licence she can lose, which is precisely what makes the statements worth more.
The failure mode is a brand asking a non-credentialed creator to make the second kind of statement because it is cheaper. That is bad for the creator, who is exposed without protection, and bad for the brand, which has just made a health claim through someone with no standing to make it. If your product’s pitch is health, the credential is not a premium option. It is the requirement.
Where credentialed food content actually gets used
Savani’s work spans clinical, community and creator settings, and the range is instructive because it shows what nutrition communication looks like at different scales.
Clinical and community teaching. Weekly classes for adolescents at a children’s hospital, built around how nutrition and physical activity together affect health and self-confidence. This is the least glamorous and probably the most consequential work.
Retail education. Free nutrition sessions and recipe demonstrations inside supermarkets, which is where most people actually make food decisions. A dietitian standing next to the shelf is a genuinely different intervention from a post.
Social content. Science-based nutrition information, recipes and food finds, reaching people who will never book an appointment or attend a class.
Each reaches a different person. The supermarket work in particular is worth noting for any local food brand: point-of-decision education from a credible source moves product in a way that awareness content does not.
What this means for a food brand’s marketing
Match the claim to the credential. This is the whole rule, and it resolves almost every question about who to work with.
If you want someone to say your product is delicious, you want a reviewer. Tea Kingley’s account is built entirely on the verdict, and a positive one from a genuine reviewer is powerful precisely because she also publishes negative ones. Leslie Kiszka does the same alongside her own home cooking.
If you want someone to show people what to make with your product, you want a recipe creator. Nancy of NourishByNancy works within gluten-free and dairy-free constraints, which is ideal if your product genuinely fits them and a liability if it only nearly does.
If you want someone to explain what your product does nutritionally — protein content, glycaemic impact, whether it suits a specific condition — you want a dietitian, and only a dietitian.
If you are budgeting the work, Christine LaPuma’s profile covers how creator rates are actually built.
The brands that get this wrong usually do so by asking the wrong person for the right message. A reviewer asked to make nutrition claims either refuses, which wastes the booking, or agrees, which creates a problem.
Why credentialed creators are harder to work with, in a good way
A dietitian will decline more work than a general creator, and will negotiate on the content itself rather than just the fee.
She will not say a product is healthy because you paid her to. She will ask for the label, ask what the claim is based on, and sometimes tell you the claim does not survive contact with the evidence. She may want to caveat something you would rather she stated plainly.
All of that is friction, and all of it is the reason the endorsement is worth having. An audience that follows a dietitian does so specifically because she will not say things that are not true. A brand buying that audience is buying the restraint, and undermining the restraint destroys what it bought.
For makers whose products lean on ingredient stories, this is worth internalising early. L’Nando Bakery’s pitch is simple ingredients and no preservatives, a claim about composition, which is verifiable and safe. The moment a claim moves from “what is in it” to “what it will do for you”, it needs a different kind of spokesperson.
What to take from eatingwithadietitian
For creators: a credential is a durable competitive advantage in a field where almost nobody has one. It narrows the work you can take and raises the value of the work you can.
For food brands: decide what you actually need said, then hire the person qualified to say it. Most influencer-marketing disappointment in the food category traces back to that one mismatch — and most influencer-marketing risk traces back to it too.
