Evidence-led nutrition, written for every body, everywhere
Dietitian Without Borders is a registered-dietitian resource for people who want clear, honest answers about food — no gimmicks, no fear-mongering, no one-size-fits-all. Just the science, translated into something you can put on a plate today.
Why "without borders"
The name carries two meanings. The first is global: good nutrition is not the property of any one country, cuisine, or income bracket. Beans and lentils feed athletes and grandparents alike; rice, maize and millet anchor diets across continents. We try to write in a way that travels — drawing on international guidance and the foods people actually eat, rather than assuming everyone shops the same aisles.
The second meaning is about gatekeeping. Too much nutrition advice draws hard lines: foods that are "good" or "bad", plans you either follow perfectly or fail. We don't work that way. Whether you're fuelling an ultramarathon, managing IBS, eating fully plant-based, living gluten-free out of medical necessity, or feeding yourself through a tube at home, the same principles apply — start with the evidence, respect the individual, and keep it practical.
Everything here is produced by the Dietitian Without Borders team and reviewed against current registered-dietetics guidance. We write explainers, not prescriptions: nothing on this site replaces personalised advice from a clinician who knows your history.
What we cover
Eight areas where good, calm, evidence-led guidance makes a real difference. Each links to a hub of guides, explainers and worked examples.
Sports & endurance fuelling
From the 60g-an-hour baseline to gut-trained 90g strategies for long efforts — how to fuel without bonking or GI distress.
Explore Gut healthLow-FODMAP & IBS
The Monash three-step method done properly: a short elimination phase, structured reintroduction, then personalisation — not a forever diet.
Explore Plant-forwardPlant-based & vegan eating
Protein, B12, iron, omega-3 and calcium covered confidently, with everyday meals that don't rely on expensive specialty products.
Explore MedicalGluten-free living
Coeliac-safe eating built on the evidence — label literacy, cross-contamination, and a varied diet that isn't built around "free-from" aisles.
Explore ClinicalDiabetes & CGMs
How carbohydrate, fibre and timing show up on continuous glucose data — reading your own numbers without obsessing over them.
Explore Home careTube feeding at home
Plain-language support for people and carers managing enteral nutrition outside hospital — routines, hygiene and troubleshooting.
Explore SwallowingDysphagia support
Texture-modified eating that stays safe and still tastes like food, framed around the international descriptors clinicians use.
Explore EverydaySnacks & weeknight meals
Honest energy bars and fast, nourishing dinners — the unglamorous backbone of eating well when life is busy.
ExploreEndurance fuelling, by event length
Carbohydrate needs during exercise scale with how long you're out there. A single carb source oxidises at up to ~60g per hour; glucose-fructose blends and a trained gut let well-prepared athletes push higher for ultra-distance.
Often little or none needed; rinse or small amounts
Single carbohydrate source is sufficient
Glucose-fructose mix + gut training
“Nutrition science is rarely about willpower and almost never about a single miracle food. Our job is to translate the evidence honestly, respect the person in front of us, and leave them with something they can actually do tomorrow.”
How we work
A simple, repeatable standard behind every article we publish.
Start with the evidence
We anchor each topic in current registered-dietetics guidance and reputable bodies — NHS, Monash FODMAP, Coeliac UK, Diabetes UK, IDDSI and peer-reviewed sport science — and cite the numbers we use.
Translate, don't dilute
Guidelines are turned into plain, British-international English with real foods and real portions, so the advice survives contact with a busy week.
Respect the individual
We flag where "it depends" — on your goals, your gut, your medication, your culture and your budget — instead of pretending one rule fits everyone.
Stay in our lane
We publish explainers, not diagnoses or prescriptions. When something needs a clinician who knows your history, we say so plainly.
Have a question, a correction, or a topic request?
We genuinely want to hear it — especially from clinicians, athletes and readers spotting gaps. Good nutrition information gets better when more people pressure-test it.
