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 for pregnancy. The one rule that matters is pasteurisation: pasteurised yoghurt is safe, unpasteurised is not. Everything after that is about picking a good one. If you want it in one line: plain, low in added sugar, and pasteurised on the label. The unsweetened range is the plain end of what we make.
Is yogurt safe during pregnancy?
Pasteurised yoghurt is safe. Unpasteurised is not. 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 avoid list.
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 a newborn 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. That is a fair question to put to any producer, and it is not one to assume the answer to.
Soft cheese rules cause a lot of confusion alongside this, so it is worth separating them. The NHS restrictions on brie, camembert and blue cheese are about mould-ripened and soft ripened dairy. They do not extend to yoghurt.
What it does for you
Calcium is what the guidance leads with, and the reason is straightforward: your body is building a skeleton, and dairy is one of the easiest ways to cover the calcium that takes. USDA data gives plain low-fat yogurt about 183mg per 100g.
Protein is also an important benefit. 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.
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 compared with unstrained yogurt, about 20g per 200g against 10g. Straining also takes out some of the milk sugar, so plain low-fat Greek carries about 7g of sugar per 200g against about 14g for plain low-fat regular.
The trade runs the other way on calcium, because straining removes some of that too: 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 covers the full picture.
Choosing a good one
The NHS is specific about the kind to reach for: low-fat and lower-sugar varieties. That points at 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.
Zayith’s Low-Fat Unsweetened tub is low fat with no added sugar, which is the pairing the guidance points at, and the rest of the unsweetened range is here. Check the pack for pasteurised milk, as you would with any brand.
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.
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 it matters more during pregnancy than usual.
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, why full fat is recommended 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.
