The average person consumes around 18g of fibre a day. The recommended intake is 30g. That gap — twelve grams, every single day — is where most of us are quietly failing our gut, and where the food on our plates can make the most difference.
I've had the Healthy Gut Cookbook by Gavin Pritchard and Maya Gangadharan on the shelf at Casa Adora since 2016. At the time it felt slightly niche. It doesn't any more. The science has caught up with what traditional food cultures have always known: that a diet built around fermented foods, legumes, wholegrains and plant diversity is one of the most powerful things you can do for your health. Hugh Fearnley-Whittingstall's Eat Better Forever and his collaboration with Tim Spector of ZOE on How to Eat 30 Plants a Week have both brought this into the mainstream. The microbiome is no longer a fringe topic.
What this gut health recipes collection offers is something slightly different. These are gut health recipes from a rural Andalucían kitchen — not a wellness clinic, not a supplement brand, not a diet plan. The Mediterranean diet has consistently ranked among the best in the world for gut health, and it's the food I cook every day: olive oil, pulses, fermented vegetables, bone broths, ancient grains. I didn't set out to build a gut health collection. I just looked at what I'd been cooking for years and realised it already was one.
Gut Health Recipes — What You'll Find Here
This collection is organised by approach rather than by meal type. Fermented foods come first, because the microbiome evidence for live cultures is the strongest we have. Legumes follow — the workhorses of high-fibre cooking and the backbone of Mediterranean peasant food. Then oats and wholegrains, high-fibre soups and broths, gut-friendly eating through history — and a dedicated collection on resistant starch, because cooking and cooling starch transforms it into prebiotic fuel. Cook it, cool it, use again.
Every recipe here is real food. Nothing has been engineered for health. Everything has been cooked, eaten and written about because it's good — and it happens to be good for you.
1. FERMENTED FOODS
Fermentation is the oldest form of food preservation and, as it turns out, one of the most powerful things you can do for your gut. Live cultures — in kefir, sauerkraut, kimchi, miso, preserved lemons, lacto-fermented peppers — feed and diversify the microbiome in ways that no supplement has convincingly replicated.
Rawia Bishara's Olives, Lemons & Za'atar — the definitive guide to Middle Eastern home cooking — is built on a tradition of preserved and fermented ingredients that predates the word microbiome by several thousand years. Preserved lemons, pickled vegetables, yoghurt-based sauces: this is gut-friendly eating as everyday food, not as a health intervention.
The full fermentation collection lives in the Fermentation Hub. The recipes below are the gut health recipes most directly relevant to your microbiome.

2. LEGUMES — BEANS, LENTILS & CHICKPEAS
If fermented foods are the gut health headline, legumes are the backbone. Chickpeas, lentils, white beans, black lentils, haricot beans — high in fibre, high in resistant starch, and deeply embedded in the cooking traditions that the Mediterranean diet is built on.
Claudia Roden's Med and Jacqueline Clark and Joanna Farrow's Mediterranean Food of the Sun both draw on the same tradition I cook from at Casa Adora: dishes where pulses are not a health-conscious substitute for something else but the point of the meal. Garbanzos a la Riojana. Palak Daal. Braised white beans with lamb. These are peasant dishes, in the best sense — economical, flavourful, and extraordinarily good for you.
The full collection of pulse and vegetable recipes lives in the Veg, Fruit & Pulses Hub. What follows are the highest-fibre, most gut-relevant dishes from that collection — chickpeas, lentils, white beans and black lentils at the centre of the plate rather than on the side.

3. OATS & WHOLEGRAINS
Oats are one of the most fibre-dense foods in the everyday kitchen, and they occupy an unusually prominent place in TFC's recipe collection — partly because of the Scottish strand that runs through this blog, and partly because they turn up everywhere once you start looking: in fish cake crusts, in skirlie, in Orcadian soup, in cranachan.
Ancient grain breads — sourdough, rye, spelt, teff, buckwheat soda bread — follow the same logic. Slow fermentation and complex grain structures mean these breads feed the gut in ways that refined white bread simply doesn't. The full bread collection lives in the Bread Recipes Hub.

4. HIGH-FIBRE SOUPS & BROTHS
Pearl barley, leeks, split peas, kale — the ingredients of Scotch broth, cock-a-leekie, medieval pottage — are prebiotic powerhouses. They're also some of the most flavourful things you can put in a pot. The fact that they happen to be exceptionally good for your gut is, frankly, a bonus.
Leeks, onions and garlic deserve a specific mention. These are among the richest dietary sources of inulin — a prebiotic fibre that feeds beneficial bacteria directly. A good leek soup or a slow-cooked garlic broth is doing more work than it looks.

5. GUT HEALTH THROUGH HISTORY
No other gut health collection has this section, and that's the point. The Cooking Through History strand on TFC has always been about more than historical curiosity — it's about recognising that the dishes humans have cooked for thousands of years often have a nutritional logic that modern food science is only now catching up with.
Ancient Egyptian lentil stew. Mesopotamian lamb and barley. Greek skordalia-style barley purée. Medieval pottage with kale and pearl barley. These are some of the oldest surviving recipes in the world — and they are, without exception, high in fibre, built on legumes and wholegrains, and deeply prebiotic. That's not a coincidence. It's what people grew, cooked and ate before industrial food processing arrived to remove most of the nutritional value from the equation.

6. COOK IT, COOL IT, USE AGAIN — RESISTANT STARCH RECIPES
There is a specific mechanism worth understanding. When you cook a starchy food — rice, potato, pearl barley, oats — and allow it to cool, some of the starch retrogrades into a form that resists digestion in the small intestine. Instead of being absorbed as glucose, it passes through to the large intestine and ferments, feeding your gut bacteria directly. This is resistant starch, and it is one of the most potent prebiotic foods in the everyday kitchen.
It is also, conveniently, the science behind some of the most satisfying cooking on this blog. Stovies are not just thrift — they are nutritionally superior to freshly boiled potatoes. Nasi goreng requires day-old rice, and day-old rice has significantly more resistant starch than rice eaten straight from the pot. The overnight oats in this collection deliver maximum RS2 benefit precisely because they are never cooked at all.
