The Receipts

I’m a punk cook, not a professor — and I’m not going to pretend otherwise. But when I write about lipid disorders, the gut–brain axis or plant-based nutrition, it’s not something I picked up on TikTok. It comes from medical university conferences, scientific societies and training with people who do dietetics for a living. Here are the receipts — scans included, no smoke and mirrors.

Why should you care?

The internet is full of food bloggers quoting other food bloggers. I cook professionally every day and I write about food in public — so I’d rather know what the science actually says. The names below may not ring a bell outside Poland, so I’ve added one line of context to each. Poland takes its dietetics seriously.

Scientific conferences

  • “Gut–Liver–Brain Axis — Practical Implications” — 8th Scientific and Training Conference on Functional Dietetics, Pomeranian Medical University in Szczecin, 2020. A CME-credited event for physicians and pharmacists. Certificate issued in English — it opens the gallery below.
  • PAD “Mind & Dietetics” — 4th (2020) and 5th (2021) national conferences at the Medical University of Łódź; the 2021 edition ran under the patronage of Poland’s National Institute of Public Health. This is where my two big topics meet: food and the head.
  • “Nutrition Without Borders” — 4th International Scientific Conference, 2021.
  • “Plant-Based Diets — Pros and Cons” — Academy of Sports Dietetics, Warsaw, 2020.
  • Food Forum expert: “New Perspectives in the Diet Therapy of Metabolic and Lifestyle Diseases” — conference of Food Forum, Poland’s leading dietetics journal, 2022.

Training and webinars

  • Plant-Based Diet training (hands-on + theory) — taught by Iwona Kibil, Poland’s leading plant-based dietitian.
  • “Diet in the Therapy of Lipid Disorders” — Polish Lipid Association, 2021.
  • “Plant-Based Diet — What You Need to Know” — EIT Food & the Polish Academy of Sciences, part of the EU Horizon 2020 V-PLACE project, 2020.
  • “How to Invest in Calories” parts I & II — Institute of Psychodietetics, 2021 (healthy eating, weight management, volumetric diet).

Membership

I’m a member of the Polish Society of Lifestyle Medicine — an organisation of physicians and specialists working with evidence-based nutrition, movement, sleep and mental health.

Does this make me a dietitian? No.

A participation certificate is not a university degree and not a licence. I don’t treat patients and I don’t write therapeutic meal plans — that’s what clinical dietitians are for. What these papers mean is simple: I do my homework. When I cook and write about food, I know what I’m talking about — and when I don’t, I check the research, not the comment section.

The kitchen is my space for lifestyle medicine.
I'm not a dietitian or a doctor – I'm a chef, and a member of the Polish Society of Lifestyle Medicine. Nutrition is essential to a modern kitchen, and that's nothing new: working from Hippocratic dietetic principles was part of a cook's craft centuries ago. At Rude Kitchen I tie that tradition to modern science — and to lifestyle. Read more about how I bring cooking and lifestyle medicine together on the About page.
