Building a safe-foods list in remission

A safe-foods list is a personal record of meals and ingredients that have reliably not caused you trouble. It is not a diet, it is not a rule about what anyone else should eat, and it is not evidence about inflammation. It is a practical shortlist for the days when you have no energy to think about food.

The problem with most safe-foods lists is that they are built during a flare, when almost nothing feels safe, and then never revisited. They shrink. Years later, some people are down to a handful of meals they trust. Remission is the window to widen the list again, and it takes a bit of structure to do that without guessing.

What counts as evidence, and what doesn't

A single bad reaction to a meal is weak evidence. Symptoms in IBD and IBS have a lot of moving parts: stress, sleep, medication timing, hormones, an infection you didn't notice, how much you ate, how fast, how late. Any of those can turn a neutral food into a suspect.

What makes a food genuinely useful on your list is repetition. Three or four separate occasions, spread over weeks, eaten in different contexts, with no reaction each time. That is a food you can rely on when you are tired and need to eat something without a decision.

It works the other way as well. One bad night after a curry does not mean curry is out for life. It means curry goes on a shortlist of things to test again later, deliberately, when you are well.

Worth naming honestly: food intolerance and inflammation are different things. A food can make you feel awful without making your disease worse, and disease activity can rise without any food changing at all. Blood tests, faecal calprotectin and scopes are what tell you about inflammation. Your list tells you about comfort and confidence, which matter too, but they are not the same measure.

Why remission is the right time to widen the list

During a flare, the gut reacts to almost everything, so test results are hard to read. You can eat a food you have tolerated for twenty years and feel terrible. Nothing you learn in that period should be written down as permanent.

In remission, the background noise is lower. If you eat something and nothing happens, that result means something. If you eat something and you do react, that result also means something, because it is not being drowned out by everything else.

There is also a longer-term reason. A very narrow diet makes it harder to get enough protein, fibre, calcium, iron and other nutrients, and it may reduce the variety of your gut bacteria. The evidence on exactly how much that matters for IBD outcomes is mixed, but the nutritional argument for a wider diet is not controversial. This is a good thing to raise with a dietitian who knows IBD, particularly if you have had surgery, a narrowing in the bowel, or a history of low iron or vitamin levels.

Reintroducing one food at a time

Before you start, it is worth checking with your IBD team that you are actually in remission rather than just having a quiet spell, and that there is nothing about your disease or recent surgery that makes food testing a bad idea right now. Results from an unsettled gut are not worth writing down.

The method is boring on purpose. Boring is what makes the answer readable.

1. Pick one food, not a meal. "Lentils" is testable. "Mum's stew" is not, because it contains nine things.
2. Start with a small portion, on a day that is otherwise ordinary. Not the day before a long drive, not the night of a wedding.
3. Change nothing else that day. Same medication timing, same sleep, no second new food.
4. Give it 48 to 72 hours before you judge. Some reactions are quick and some are not.
5. If nothing happens, repeat it two or three more times over the following fortnight, with a slightly larger portion. Consistency is the point.
6. If something does happen, stop, note what and how severe, and wait until you are back to baseline before testing anything else. You can retry the same food in a month or two, possibly cooked differently or in a smaller amount.

Preparation often matters more than the food itself. Cooked and peeled apple behaves differently from raw apple with skin. Blended soup behaves differently from chunky soup. Smooth nut butter is not the same test as a handful of almonds. If a food fails in one form, it is reasonable to ask whether a gentler form is worth trying, rather than crossing the whole thing off.

One caution: if you have been told there is a narrowing or stricture, or you have had bowel surgery, the usual advice about fibre and textures may not apply to you. Ask your IBD team before testing high-residue foods such as raw vegetables, skins, pips, sweetcorn or nuts.

How to record a good day

Most people only log when something goes wrong. That leaves you with a long list of suspects and no list of safe foods at all, because the good days were never written down.

A good-day entry does not need to be long. It needs the meal, roughly what was in it, and confirmation that the rest of the day was unremarkable. Two lines is enough.

Recording stool form is worth the small effort, because "fine" means different things on different days. The Bristol Stool Chart gives you a number instead of an adjective, which makes patterns easier to see weeks later. For the wider question of what to log and how often, the food diary guide covers the mechanics.

What the list should look like after a few months

Three tiers works well for most people. Safe: eaten repeatedly with no reaction, no thought required. Sometimes: tolerated in small amounts or particular preparations, fine occasionally. Not yet: caused a clear reaction more than once, parked for a future retest rather than banned.

"Not yet" is deliberate wording. Lists that use "never" only ever get shorter. Reviewing the parked items every six months or so, while you are well, keeps the whole thing honest.

Take the list to appointments. A dietitian can look at it and spot gaps you cannot see, for example that you have quietly dropped every source of calcium, or that your "not yet" pile is mostly high-FODMAP foods, which points at a different conversation. The appointment prep guide covers how to condense this into something readable in a short consultation.

Symptoms that need same-day care

Stop testing foods and contact your IBD team or urgent care the same day if you have severe or worsening abdominal pain, heavy or persistent rectal bleeding, a fever above 38°C, vomiting that stops you keeping fluids down, signs of dehydration such as dizziness on standing or passing very little urine, or the combination of a distended abdomen, cramping and no wind or stool passing, which can signal an obstruction. These are not food reactions to log and review later.

What to ask your team

• Am I in remission by objective measures, not just how I feel, so that reintroduction results are meaningful?
• Are there foods or textures I should avoid because of a stricture, recent surgery or where my disease is?
• Can I be referred to a dietitian with IBD experience to look at gaps in what I am eating?
• Should I be checked for iron, B12, vitamin D or calcium given how narrow my diet has been?
• Is a structured approach such as a short low-FODMAP trial with dietitian supervision worth considering for my ongoing symptoms?

None of this is a substitute for the advice of the people treating you. It is a way of arriving at those conversations with something better than a shrug.
