What actually happens when food meets food? 🧪
Squash two ingredients together and watch them react. Send a meal on a seven-metre journey through your insides. Work out why beans do that. Everything here runs on real food chemistry — and where a rule is just an old kitchen superstition, we say so instead of pretending.

Pick a zone 👇
Three rooms in the lab. They share the same pantry, so anything you find in one turns up in the others.
Mix Lab
Drop any two of 109 ingredients into the bowl and watch them argue. Curdling, fizzing, tenderising, nutrient boosts and blocks — with the reason in one plain sentence.
Mix something →The Journey
Send a food in at the top and follow it all the way down. Real timings, a gut-mood meter, and one very popular myth busted on the way through.
Swallow something →Gut Check
Tick what you ate and how you feel, and see which known patterns fit. A pattern-spotter, emphatically not a diagnosis — and it says so on every card.
Spot a pattern →Or run a bench experiment 🔬
Four kitchen reactions, animated and metered. Change the amounts and the numbers move with the picture — same maths behind both.
Baking Soda & Vinegar
Set the amounts and watch the fizz. Which one runs out first, how much gas you get, and how far past the rim it goes.
Run it →Why Milk Curdles
Add acid at any temperature and watch the protein hold or let go. The pH is titrated properly and the threshold moves with the heat.
Run it →Caramelisation
Water boils off, the syrup concentrates, and the pan climbs the candy ladder from thread to hard crack — then starts to colour.
Run it →Egg White Foam
Whip whites on screen. Sugar, a stray speck of yolk, the whisk in your hand and the bowl all move where the foam tops out.
Run it →Is any of this true? 🤔
Food combining has a lot of folklore attached to it, and most "never eat X with Y" rules fall apart the moment you look for evidence. So this lab does three things with them:
- Real chemistry gets shown as real chemistry. Acid curdles milk. Pineapple tenderises meat. Vitamin C multiplies the iron you absorb from plants. Tea blocks it. These are demonstrable and the lab treats them as facts.
- Traditional rules get a badge, not a promotion. The Ayurvedic rule against fish with milk appears in the Mix Lab wearing an Old Wives' Tale label. It is genuinely part of several food cultures, and it is genuinely not supported by evidence. Both halves are worth knowing.
- Popular myths get busted on purpose. Drinking water with a meal does not dilute your stomach acid into uselessness. The Journey has a toggle that shows you exactly that.
How to use the lab 🧭
- Start in the Mix Lab. Tap any two ingredients and the verdict appears instantly — no submit button anywhere in the lab.
- Take a food into The Journey to see what happens to it after you swallow, with real stage timings.
- Use Gut Check when something is actually bothering you — tick what you ate and how you feel, and it matches against documented patterns.
- Nothing needs an account and nothing you tick leaves your browser. Your Mix Lab discovery count is stored on your own device.
All three zones share one pantry of 109 ingredients, so anything you find in one turns up in the others.
Questions people actually ask
Is the Kitchen & Gut Lab free?
Yes. No account, no sign-up, no paywall, and nothing you tick or mix is sent anywhere — every zone runs entirely in your browser.
Can this tell me if I have a food intolerance?
No. Gut Check matches what you ate against well-documented patterns and points you at what is worth asking a doctor about. It cannot diagnose anything, and confirming an intolerance needs a clinician — in the case of coeliac disease, a blood test taken while you are still eating gluten.
Where does the food science come from?
Each zone lists its own sources at the bottom of the page — the NIH Office of Dietary Supplements for nutrient absorption, NIDDK for digestion, Monash University for FODMAPs, NHS, NICE and Coeliac UK for the clinical patterns. Where a rule is traditional rather than demonstrated, it is labelled as folklore instead of being cited to a source that does not support it.
What are the bench simulators?
Four animated kitchen reactions with live numbers behind them: baking soda and vinegar, caramelisation, milk curdling and egg-white foam. Change the amounts or the temperature and the picture and the figures move together, because both come from the same calculation.
Sources & references 📚
Each zone cites the sources for its own claims. Together the lab draws on:
- NIH Office of Dietary Supplements — Iron — heme vs non-heme absorption, vitamin C and tannins (Mix Lab)
- NIH Office of Dietary Supplements — Calcium — oxalates, and why spinach withholds its own calcium (Mix Lab)
- NIDDK — Your Digestive System & How It Works — the stage-by-stage anatomy (The Journey)
- Monash University — FODMAPs and IBS — the group that defined FODMAPs (Journey & Gut Check)

Assumptions & limitations
The lab is built to be understood in a minute, which means every zone trades some precision for clarity. Specifically:
- Every zone is a simplified illustrative model, not a simulation of your body. Real digestion and real food chemistry involve far more variables than any of these pages expose.
- Food composition figures are typical values for a generic version of each ingredient. Variety, ripeness, growing conditions and how you cooked it all move the numbers.
- Digestion timings are population ranges. Age, activity, medication, gut conditions and the rest of your day all shift them, sometimes substantially.
- The lab describes what usually happens. It cannot account for allergies, intolerances, medication interactions or any individual medical condition.
Nothing in the lab is medical or nutritional advice. It is a simplified, illustrative model built to make food science visible, not a clinical tool. If something you eat is genuinely causing you problems, that is a conversation with a GP or a registered dietitian.
