When clients first ask me which foods to avoid in pregnancy, they expect a list — the laminated card, the forty-item version their aunt, their group chat and three apps have each added to. What they actually need is the opposite: a much shorter list, explained properly, and permission to put back the eight or nine things they quietly gave up out of fear.
By the time a pregnant client reaches me, the risk on her plate is almost never the problem. The problem is what has left it — fish gone entirely, cheese gone entirely, eggs treated as a hazard. The real list of foods to avoid in pregnancy is short, specific and built on mechanisms, and the mechanism is the useful part: it tells you how to make a food safe rather than only that it is forbidden. One safety note first — a fever, severe or bloody diarrhoea, persistent vomiting, flu-like aching after a meal you are worried about, or your baby moving less than usual all need your midwife, verloskundige or doctor the same day, not a change to your breakfast.

The Real List Is Short and Specific, and Over-Restriction Is the Commoner Problem
Almost everything on a legitimate avoid-list traces back to a few mechanisms: a bacterium that behaves unusually in the cold, a parasite living in soil and animal muscle, salmonella in eggs, mercury in a few large fish, vitamin A in concentrated form, alcohol, and a short list of plant compounds with uterine or hormonal effects. Once you understand those, you stop needing the list.
Now the half I spend most of my clinic time on. [TK: clinical observation — what clients most often cut out unnecessarily] Over-restriction is not a harmless error, and its costs are specific:
- Fish disappears, and with it the omega-3 fats and iodine genuinely wanted in pregnancy.
- Dairy disappears after a scare about soft cheese, taking calcium and protein.
- Eggs become suspect, removing the cheapest tolerable protein of early pregnancy.
- Meat is dropped or overcooked, and iron falls away with it.
If nausea governs what you can face, eating through morning sickness suits this phase better; if you eat no meat or animal foods, vegetarian and vegan pregnancy nutrition covers the balance, as does my trimester-by-trimester pregnancy plan.
Listeria: Why the Concern Is Chilled, Ready-to-Eat and Unpasteurised
Most food bacteria are held back by refrigeration. Listeria multiplies slowly at fridge temperature instead, so what it exploits is a food already contaminated, kept cold and eaten without further cooking. Pregnancy lowers your defences and the bacterium can cross the placenta. Infection is uncommon, and it is the one item here I treat with least flexibility.
So the category is not "soft cheese". It is chilled, ready-to-eat and unpasteurised:
- Unpasteurised milk and anything made from it — village raw milk, raw-milk beyaz peynir, many tulum cheeses, some artisan ezine, anything labelled rauwmelkse kaas.
- Mould-ripened soft cheeses — brie, camembert, blue — pasteurised or not, because their texture and acidity suit the bacterium.
- Pâté of every kind, leverpastei and ciğer ezmesi included.
- Cold-smoked fish and chilled ready-to-eat seafood, smoked salmon included.
[TK: confirm your position on cold-smoked salmon and smoked fish] - Chilled prepared foods eaten cold — deli salads, salad bars, cut fruit, old sandwiches.
Heat destroys listeria, so the same foods are a non-issue when properly hot — cheese melted into a börek, leftovers reheated until steaming right through. [TK: confirm the reheating standard you give for chilled ready-to-eat foods]
Pasteurisation does that work before the food reaches you, so the label matters more than the cheese's name. Supermarket beyaz peynir in the Netherlands and Turkey is generally pasteurised; the question at a Turkish grocer is whether the milk was, not whether the cheese is soft.
Toxoplasma and Salmonella: Raw Meat, Cured Meat, Eggs and Unwashed Produce
Toxoplasma is a parasite with two kitchen routes. It forms cysts in the muscle of infected animals, so undercooked meat carries it, and it is shed into soil and cat faeces, so unwashed produce and gardening carry it. Thorough cooking destroys the cysts:
- Cook meat right through — no pink in mince, poultry, sausages or kebab, including the rare steak people ask about.
- Cured and air-dried meats are salted rather than cooked — raw sucuk, pastırma, salami, prosciutto, filet americain, and broodje tartaar, which is raw minced beef. Heat changes this: sucuk cooked into a menemen stays on your table.
- Traditional çiğ köfte made with raw mince belongs here. The bulgur version sold everywhere now contains no meat and is a different food.
- Kokoreç and other offal street foods must be cooked right through, and rest on the grill's hygiene.
- Wash salad, herbs, fruit and vegetables well, and wear gloves for gardening.
Salmonella and eggs run on different logic, and the answer depends on where you live. The risk is about the flock and whether the egg has been heat-treated, which is why guidance on runny eggs and homemade mayonnaise differs between countries: some vaccinate laying hens under a national scheme and relax the advice, others do not. Ask your midwife what applies where you are; cooking the egg until white and yolk are firm removes the question.
Nutrition here works alongside, and never replaces, your midwife or doctor, and suspected food poisoning in pregnancy is a same-day call to them.
Mercury and Fish: A Short Avoid List Inside a Much Larger Invitation
Methylmercury accumulates up the food chain, so the concern is a small number of large, long-lived predatory fish rather than fish as a category. Those few are worth avoiding, a couple more worth limiting. [TK: confirm the high-mercury fish you name, and your weekly oily fish guidance]
Here is what gets lost. Oily fish is actively wanted in pregnancy rather than merely permitted: the omega-3 fats in salmon, mackerel, sardines, anchovies and herring support fetal brain and eye development, and fish is a good source of iodine. Most pregnant women I see eat far less oily fish than they could, and many eat none, because one headline removed a whole food group. My guide to omega-3 fats and where to get them covers the alternatives if fish is genuinely off the table.
Two things get wrongly folded into the mercury question: raw fish — sushi, Dutch maatjesharing, lakerda — is a bacterial and parasite matter, and smoked salmon a listeria one.
Alcohol, Caffeine and Liver: Three Separate Conversations About Dose
Alcohol, stated plainly: there is no known safe amount in pregnancy, which is why the advice is none. It crosses the placenta freely and the developing brain is vulnerable throughout. Many women also carry something silently, so let me say it plainly: a drink taken before you knew you were pregnant is something every clinician has heard, and no purpose is served by months of fear about it. Mention it to your midwife, then let it go. Worth a question are the drinks nobody counts: boza and other lightly fermented traditional drinks, non-alcoholic beers that are not entirely alcohol-free, and dishes finished with wine that is not cooked off. [TK: confirm your advice on boza and lightly fermented traditional drinks]
Caffeine is dose-dependent rather than forbidden, and the limit is a daily total, not a ban on coffee. [TK: confirm the caffeine limit in milligrams you work with, and its cup equivalents] Women overshoot on what they do not count — glasses of black tea across an afternoon, green tea, cola, chocolate, energy drinks. Tea and coffee also reduce iron absorption, so move them between meals.
Liver is the item nobody explains, and the mechanism is the point. It is an extraordinarily concentrated source of preformed vitamin A — retinol — which in high doses harms a developing baby. That is why liver, liver pâté, leverworst, ciğer and cod liver oil supplements carry a caution, and why the caution does not extend to vitamin A in general: the beta-carotene in carrots, apricots and dark leafy greens is converted as needed. [TK: confirm the preformed vitamin A ceiling you use, and whether liver is avoided or limited]
Supplements and Herbal Teas: Herbal Does Not Mean Inert in Pregnancy
I trained in phytotherapy as well as dietetics, so let me be straight about the part of the shelf I find most mishandled in pregnancy.
Plants contain pharmacologically active compounds. That is why they work, and it is why herbal is not a synonym for gentle. Several herbs used in women's health act on the uterus or on hormones, and some turn up in teas sold as calming: sage in medicinal amounts rather than a pinch in cooking, large amounts of parsley, liquorice root, hibiscus, concentrated fennel, and raspberry leaf outside late pregnancy and professional guidance. Anything sold for detox or slimming I would keep out of a pregnancy, because potency and contents are frequently unstated. [TK: confirm which herbal teas you limit or avoid, and in what amounts]
Dose and concentration decide almost everything: a cup of linden is not the exposure a daily extract capsule is, and the capsule is where I see problems.
On supplements the useful list is short. Folic acid before and in early pregnancy and vitamin D have real evidence behind them, iodine matters where dairy and fish are low, and iron is worth taking when your bloods say so. I ask clients to bring the whole cupboard, because the risks sit in high-dose single nutrients, retinol products, and multivitamins not designed for pregnancy. My guide to which supplements are worth taking sets out the reasoning.
A Sample Day, and the Much Longer List You Do Not Have to Avoid
Here is how these principles come together on an ordinary day. This is illustrative rather than a prescription, and if you are managing gestational diabetes carbohydrate distribution comes first.
- Breakfast: eggs cooked through as menemen, pasteurised beyaz peynir, olives, washed tomato and cucumber, wholegrain bread, tea after the meal.
- Mid-morning: yoghurt with fruit and walnuts, or bread with tahini and pekmez.
- Lunch: lentil soup, a washed salad with olive oil and lemon, and bulgur pilavı.
- Afternoon: fruit and almonds, or a glass of ayran.
- Dinner: baked oily fish such as salmon or mackerel regularly, a bean or zeytinyağlı vegetable dish otherwise, with rice or potatoes and cooked vegetables.
Notice how little of that is restriction. The only safety rules in play are cook the eggs, wash the salad, check the cheese label, and keep tea off the iron-carrying meals.
And here is the list nobody hands you — what you are not being asked to give up:
- Pasteurised beyaz peynir, hard cheeses, lor, halloumi, yoghurt, ayran and kefir, and eggs cooked through as often as you like.
- Fish, oily fish included — wanted rather than tolerated.
- Spices, acılı food, turşu, garlic, onion, lemon, honey, pekmez and tahini.
- Pineapple, papaya, aubergine, chickpeas, bread and potatoes — on somebody's list, and on nobody's.
Common Pregnancy Food Safety Myths
"I have to give up all soft cheese for nine months."
The risk sits with unpasteurised milk and with mould-ripened cheeses such as brie, camembert and blue, not with softness. Pasteurised beyaz peynir, feta, lor, halloumi and mozzarella are fine, and even brie is safe cooked thoroughly into something hot.
"Fish is dangerous in pregnancy, so I have stopped eating it."
This is the most costly misunderstanding in pregnancy nutrition. A few large predatory species carry a genuine mercury concern; salmon, mackerel, sardines and anchovies are recommended for the omega-3 and iodine your baby is using.
"Spicy food can cause a miscarriage or bring on early labour."
There is no credible evidence for this. Spicy food may worsen reflux late in pregnancy, which is a comfort question you may decide for yourself.
"Pineapple and papaya will end the pregnancy."
Both beliefs rest on compounds that do exist — bromelain in pineapple, an enzyme in unripe papaya latex — and neither reaches a meaningful dose in fruit you would eat.
"I should stop exercising and avoid cold drinks."
Movement in pregnancy supports blood pressure, blood glucose, mood and sleep, and the adjustments concern intensity rather than stopping — one for your midwife. Cold water does not harm a baby, and in a nauseous first trimester it may be the only thing you keep down.
Working With Hanzi Nutrition
I am a dietitian, and my position on pregnancy food safety is unfashionably calm. The real list is short and built on mechanisms you can learn in an afternoon; the women I meet are almost never in trouble over something on their plate, but because fear took fish, cheese and eggs away.
At Hanzi Nutrition, I work fully online with clients across the Netherlands, Belgium, Germany and Turkey, in English and Turkish, and pregnancy is among the areas I support most often through my pregnancy and fertility nutrition service. We begin with a first consultation covering your trimester, your appetite, your bloods, every supplement and herbal tea in the cupboard, and what you have cut out and why. From there I build a personalised plan around your culture, your usual foods, your schedule and your appetite — two kitchens, if you cook Turkish food in a Dutch supermarket — with the mechanism explained for everything that stays on it. Nutrition here works alongside your midwife, verloskundige or obstetrician and never replaces that care. Then I stay with you across the trimesters, because week nine and week thirty-two want different food.
If you are living on a shrinking list of safe foods and want the short real list plus permission to eat properly again, book a consultation with me today through my personalised plan service.
Hanzi Nutrition offers dietitian-led nutrition counselling across the Netherlands, Belgium, Germany, and Turkey, fully online, in English and Turkish. This article is general education and not a substitute for individual medical care — food safety guidance differs between countries and is revised over time, so your midwife, verloskundige or doctor's current advice takes precedence here, and suspected food poisoning, fever or reduced fetal movement needs same-day assessment. Please coordinate any changes to your nutrition or supplements with your doctor.
