Yes. The NHS lists dairy foods including yoghurt as important in pregnancy for their calcium, and puts plain or lower-sugar yoghurt on its list of healthy snacks. The one rule that matters is pasteurisation: pasteurised yoghurt is safe in pregnancy, unpasteurised is not. Everything after that is about picking a good one. In one line: plain, low in added sugar, and pasteurised on the label.
The pasteurisation rule
The NHS puts “any pasteurised milk, butter, yoghurt, cream and ice cream” on its safe to eat list and “unpasteurised milk, cream, yoghurt, butter and ice cream” on the list to avoid.
The reason is listeria. Unpasteurised and soft ripened dairy may contain listeria bacteria, which can cause listeriosis, and the NHS is direct about the consequence: listeriosis “can cause miscarriage or stillbirth, or make your newborn baby very unwell”. Pasteurisation is the heat step that kills listeria in the milk, which is why the whole NHS answer turns on it.
So check the pack for the word pasteurised. If it does not say, ask the brand before you buy. It is a fair question to put to any producer, and not one to assume the answer to.
Soft cheese rules cause a lot of confusion alongside this, and they are a separate matter. The NHS restrictions on brie, camembert and blue cheese are about mould-ripened and soft ripened dairy. They do not extend to yoghurt.
What yoghurt does in pregnancy
Calcium is what the guidance leads with, and the reason is pretty clear: your body is building a skeleton, and dairy is one of the easiest ways to cover the calcium that takes.
Protein matters for a more practical reason. Appetite in pregnancy is unpredictable, and there are stretches where a full plate is unappealing. A bowl of yogurt is protein you can actually get down on those days, which is worth more than a theoretically better meal you do not eat.
Then there are the cultures, the part that separates yoghurt from milk. The fermentation is done by two organisms, Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, and the European Food Safety Authority has assessed them for improved lactose digestion in people who struggle with milk sugar.
If dairy has been sitting badly, a live yoghurt is often easier to manage than a glass of milk.
Constipation is the other digestion question in pregnancy. The NHS notes that hormonal changes can constipate you very early in pregnancy, and its advice is fibre, water and exercise rather than yoghurt.
A systematic review of probiotic yogurt in pregnancy reports a randomised trial in which both probiotic and ordinary yogurt improved constipation symptoms, while being clear that the wider evidence is mixed. Yoghurt may help, and a persistent problem belongs with your midwife.
There is also the plain fact of what it replaces. Between-meal hunger in pregnancy is real, and it usually gets answered with sugar. Plain yoghurt with fruit is on the NHS healthy-snacks list and a packet of biscuits is not.
Greek or regular
Greek yogurt is strained, which removes much of the watery whey and roughly doubles the protein. USDA records put plain low-fat Greek at about 20g of protein per 200g against about 10g for plain low-fat regular. Straining also takes out some of the milk sugar, so Greek carries about 7g of sugar per 200g against about 14g for regular.
The trade runs the other way on calcium, because straining removes some of that too. The same records give 183mg per 100g for regular against 115mg for Greek.
So if you are struggling to eat enough protein, Greek is the more efficient tub. If calcium is the priority, regular is the better spoonful by a clear margin. Neither is a wrong choice, and our comparison of yogurt types sets the two side by side.
Choosing a good yoghurt
The NHS is specific about the kind to reach for: low-fat and lower-sugar varieties. That means plain or unsweetened yoghurt over the flavoured tubs and yogurt drinks, where most of the sugar in the category sits. If you want it sweeter, adding your own fruit gets you there with far less sugar than a pre-sweetened tub.
Three things to look for on the pack:
- Pasteurised milk. The non-negotiable one.
- Low added sugar. Plain and unsweetened are the safest labels. “Natural” is a marketing word rather than a sugar claim, and a natural yoghurt can still be sweetened.
- Live cultures named on the pack. If the product was fermented and not heat-treated afterwards, the cultures are still in there.
Zayith yogurt is made with pasteurised milk, which clears the first item on that list. The Low-Fat Unsweetened tub is also low fat with no added sugar, the pairing the guidance points at. It is strained the traditional way and made fresh in Lagos, and the rest of the unsweetened range sits alongside it.
What to avoid
- Anything unpasteurised, including homemade yoghurt set from raw milk, which is the one people forget.
- Heavily sweetened flavoured yoghurts and drinks as an everyday choice. They are not unsafe. They just carry a sugar load you do not need daily.
- Yoghurt sold warm or out of the cold chain. This is a general food-safety point, and the listeria risk is why it matters more during pregnancy.
After the baby arrives
Dairy stays useful while you are breastfeeding, for the same calcium and protein reasons, and there is no need to cut it unless your midwife or doctor has told you to.
For the baby, the guidance changes completely and is worth reading properly rather than assuming: when to introduce yogurt, what the guidance says about full fat for the under-twos, and what to avoid. Our guide to Greek yogurt for babies covers it.
Frequently asked questions
Does yogurt help with heartburn in pregnancy?
Some people find a cool, plain yogurt settles things and others do not. It is worth trying and not worth relying on. Raise persistent heartburn with your midwife.
Is frozen yogurt safe during pregnancy?
Pasteurised frozen yogurt is safe to eat, but treat it as a dessert rather than a serving of yogurt. Freezing reduces the live cultures and most of it carries a lot of sugar.
How much yogurt can you eat during pregnancy?
There is no special pregnancy limit. Yoghurt counts towards your dairy servings, and the NHS advice is to choose low-fat and lower-sugar options where you can. If you are getting through several sweetened tubs a day, the sugar is what to reconsider rather than the yoghurt itself. Your midwife can advise on your own diet.
