I still remember standing in the middle of Waitrose, holding a packet of lentils, genuinely unsure whether eating them would ruin my entire week.
If you have IBS, you know that feeling. The supermarket goes from being a normal errand to a minefield of hidden triggers, ingredient label anxiety, and the creeping dread of making the wrong call. I've been there — and I've spent years figuring out what actually belongs in a gut-friendly trolley.
Here's the thing nobody tells you upfront: eating well with IBS isn't about restriction. It's about trading up — swapping ingredients that inflame and irritate for ones that nourish and settle. Once you know what you're doing, the weekly shop becomes genuinely straightforward.
This is the exact list I'd build if I were starting over. UK supermarkets, realistic ingredients, no specialist health food shops required (though we'll flag a few game-changers).
First: A Quick Word on FODMAPs
You've probably heard the term. FODMAPs are a group of fermentable carbohydrates that, for people with IBS, can ferment in the gut and trigger bloating, cramping, and urgency. Around 1 in 7 people in the UK are thought to be affected by IBS, and the low FODMAP diet — developed by Monash University and now recognised by the NHS as a potentially helpful approach — is one of the most evidence-backed ways to identify and manage your personal triggers.
The key word there is personal. Not everyone with IBS reacts to the same foods. This list is built around low FODMAP principles, but it's a starting point — not a permanent prison sentence. The goal is to settle your gut, identify your triggers, then slowly reintroduce foods to find your own baseline.
One more thing before we get to the trolley: portion size matters just as much as ingredient choice. A food that's low FODMAP at one serving can tip into high FODMAP territory at a larger portion — so even the "safe" foods on this list are best eaten mindfully. You don't need to weigh everything obsessively, but awareness goes a long way.
Right. Let's shop.
🥦 The Produce Section
Vegetables to load up on:
These are your gut-friendly workhorses — low FODMAP, anti-inflammatory, and widely available in any UK supermarket.
- Courgette — endlessly versatile, brilliant roasted or spiralised
- Carrots — a gut-soothing staple; great raw, roasted, or blended into soups
- Spinach — low FODMAP at a standard serving; add to everything
- Tomatoes — fine in moderation; cherry tomatoes are especially well tolerated
- Cucumber — hydrating and completely gut-friendly
- Potatoes — the humble spud is your IBS best friend (boiled or baked, not deep-fried)
- Aubergine — underrated, very low FODMAP, great for batch cooking
- Bell peppers — red and yellow are best tolerated
- Spring onions (green tops only) — this is a game-changer. The green part of spring onions is low FODMAP. It's how you get that onion flavour without the trigger. The white bulb, however, is high FODMAP — trim it off.
- Fresh ginger — anti-inflammatory, adds warmth, and actively supports digestion
- Fresh herbs — parsley, basil, chives, coriander, rosemary, thyme. These are your flavour saviours when garlic and onion are off the table.
Fruits to grab:
- Bananas (firm/underripe) — ripe bananas are higher FODMAP, so aim for yellow-but-firm
- Blueberries — antioxidant-rich, and comfortably low FODMAP at a small handful (around 40g)
- Strawberries — generous and gut-friendly; a typical serving of around 10 (often more) sits well
- Oranges and clementines — great for vitamin C, fine at one fruit per sitting
- Kiwis — there's actually emerging evidence kiwi fruit can help with bowel regularity
- Pineapple — a surprisingly gut-friendly choice, and contains digestive enzyme bromelain
What to avoid (or handle carefully):
- Onion and garlic — the two biggest IBS triggers in existence, hidden in everything from stock cubes to salad dressings. Always check labels.
- Apples, pears, watermelon, mango — high in fructose, a common IBS aggravator
- Cauliflower and mushrooms — both high FODMAP
- Leeks — often forgotten, but high FODMAP
🍚 Grains, Carbs & Bread
This is where a lot of people get caught out — not because carbs are the enemy, but because most bread, pasta, and cereals are made with wheat, which is high in fructans (a type of FODMAP).
Good swaps:
- White or brown rice — your gut-neutral base for almost any meal
- Oats — a small portion (around 52g) is low FODMAP and genuinely great for gut motility
- Quinoa — a complete protein source, and completely gut-friendly
- Buckwheat — brilliant for pancakes, noodles, and porridge alternatives
- Gluten-free pasta — most rice or corn-based pasta is low FODMAP and now genuinely tasty
- Sourdough spelt bread — interestingly, traditionally fermented sourdough (especially spelt) has much lower FODMAP content than standard bread because the slow fermentation process breaks down fructans. Look for proper long-fermented sourdough, not the supermarket versions dressed up as artisan.
- Rice cakes — a solid snack base
Cereals worth having: Rice-based cereals and plain porridge oats are reliable. Be careful with cornflakes — most UK brands contain barley malt extract, a sneaky source of fructans (and gluten), so check the label rather than assuming "plain" means safe. Also watch for added apple juice, honey, or inulin (chicory root extract) — all high FODMAP, and all common in "healthy" cereals.
🥩 Protein
Meat & Fish
All plain, unprocessed meat and fish is naturally low FODMAP — chicken, beef, lamb, salmon, cod, tuna, prawns, eggs. The catch is in the seasoning. Most marinades, stocks, and sausages contain onion or garlic powder, often buried in the ingredients list.
Rules of thumb:
- Buy plain cuts and season yourself at home using low FODMAP herbs and spices
- Check sausage and deli meat ingredients carefully — most contain garlic or onion powder
- Tinned tuna and salmon in spring water or olive oil are great store cupboard staples
Plant-Based Protein — and This Is Where It Gets Interesting
If you're plant-based or simply trying to eat less meat, protein with IBS can feel like a hard problem. Most legumes (chickpeas, lentils, kidney beans) are high FODMAP. Many protein powders contain whey, lactose, or pea protein with additives that can trigger symptoms.
This is exactly the gap That Protein was created to fill.
Our Blissful Brown Rice & Raw Cacao is the UK's only certified Low FODMAP vegan protein — independently tested and certified by FODMAP Friendly, a leading FODMAP certification body. No onion or garlic derivatives, no additives, no gut-aggravating fillers — just clean, certified protein you can trust when your gut is unsettled.
Every blend we make is tested Low FODMAP and made with zero additives. Two of them carry the full FODMAP Friendly licence — the Blissful Brown Rice & Raw Cacao and the Double Choc Protein Porridge — while others, like our Nutty Nutty Peanut Butter (Low FODMAP at a 20g serving), make an easy everyday option when you want a gentle, gut-settling protein hit.
For anyone building a gut-friendly trolley, a certified protein powder isn't a luxury — it's one of the smartest additions you can make, because it solves the "where does my protein come from?" problem without the FODMAP guesswork.
Other plant-based protein options:
- Firm tofu — low FODMAP and versatile
- Tempeh — fermented soy, well tolerated, great in stir-fries
- Eggs — the original gut-neutral protein source, endlessly useful
- Canned chickpeas — only ¼ cup (drained and rinsed) is low FODMAP; more than this tips into trigger territory
- Canned lentils — similarly, up to ⅓ cup drained is considered low FODMAP
🧀 Dairy & Alternatives
Lactose is a FODMAP, which means standard dairy can be a trigger — but it doesn't have to be. Many people with IBS tolerate hard cheeses perfectly well, because the lactose content is negligible.
Low FODMAP dairy:
- Hard cheeses — cheddar, parmesan, feta — all fine in regular portions
- Lactose-free milk — widely available in UK supermarkets (Arla, Lactofree brands)
- Lactose-free yoghurt — check for added inulin or chicory root, which is a common prebiotic fibre additive that's high FODMAP
- Butter — lactose content is very low; fine in cooking
Dairy alternatives:
- Oat milk — check for certified low FODMAP versions; standard oat milk can be borderline depending on volume
- Rice milk — generally well tolerated
- Almond milk (unsweetened) — low FODMAP at a standard glass (around 250ml) and a genuinely easy swap. (Cashew milk is higher FODMAP, and oat milk is best kept to smaller servings.)
🫙 Pantry & Storecupboard
This is where most IBS shopping lists fall apart — because the pantry is full of hidden FODMAPs. Here's how to stock it properly.
Oils:
- Olive oil — garlic-infused olive oil is actually low FODMAP (the FODMAPs in garlic don't transfer to oil), and it's an absolute game-changer for replacing the flavour of garlic in cooking. Find it at most UK supermarkets.
- Coconut oil — low FODMAP, good for high-heat cooking
Condiments and flavour:
- Soy sauce / tamari — fine in small amounts; use for umami depth
- Maple syrup — low FODMAP in small doses; much better tolerated than honey
- Dijon mustard — usually safe; check for garlic
- Balsamic vinegar — fine in small amounts (1 tablespoon)
- Miso paste — a surprising one, but generally well tolerated at around 2 teaspoons; adds enormous depth to soups and dressings
Stock and sauces: This is where garlic and onion hide most often. Most supermarket stock cubes and jarred sauces contain onion or garlic. Look for specialist low FODMAP stocks and sauces — Bay's Kitchen (UK brand) is excellent and widely available.
Tinned goods:
- Chopped tomatoes — fine and genuinely useful
- Coconut milk — a small amount (60ml) is low FODMAP; useful for curries
- Tuna and salmon in spring water or olive oil
Nuts and seeds:
- Walnuts — a small handful (10 walnut halves) is low FODMAP
- Macadamia nuts — very well tolerated
- Pumpkin seeds — excellent for adding texture and zinc
- Chia seeds — great for gut motility; add to smoothies or overnight oats
- Peanut butter — 2 tablespoons is low FODMAP (check it's just peanuts and salt)
🥤 Drinks
- Water — the unsexy but non-negotiable one
- Green tea — anti-inflammatory and gut-supportive
- Peppermint tea — one of the most evidence-backed natural IBS remedies; keep it in the cupboard
- Black coffee — generally fine in moderation, though caffeine can stimulate the gut
- Coconut water — fine in small amounts; avoid large portions
Avoid:
- Carbonated drinks — introduce gas and bloating
- Fruit juices — high fructose content; a glass of apple juice is an IBS flare waiting to happen
- Kombucha in large amounts — trendy but high in fructose and fermentable content for many IBS sufferers

A Note on Label Reading
One of the most valuable skills you'll develop with IBS is reading ingredient labels quickly. These are the red flags to scan for:
- Onion powder / garlic powder — the sneaky cousins of the fresh versions, just as problematic
- Inulin / chicory root extract — a prebiotic fibre added to many "healthy" products; high FODMAP
- Barley malt extract — hides in cereals and "plain" cornflakes; a source of fructans and gluten
- High fructose corn syrup — common in US imports now found in UK shops
- Honey — high FODMAP; often used in cereals, granolas, and protein bars
- Apple juice / concentrate — lurks in cereals, sauces, and drinks
What's Next?
Building a gut-friendly trolley is step one. Once you've got the right ingredients at home, the next steps are:
- Build simple, repeatable meals around these ingredients — we'll share a full 7-day gut-friendly meal plan soon
- Track your symptoms as you go; a simple food and symptom diary for two weeks will reveal your personal triggers faster than any elimination protocol
- Reintroduce slowly — the goal isn't to eat low FODMAP forever, it's to find your personal threshold for each food group
