Is Greek yoghurt a low-sugar alternative to lactose-free yoghurt?

Last updated 17/01/2024

Most dairy foods contain the natural sugar, lactose, however all yoghurt contains very little lactose as the probiotic bacteria present helps to break down the lactose. The lactose present in yoghurt continues to decrease over time while it is stored in a refrigerator, as the probiotic bacteria continue to break down the lactose content.

Some yoghurts, including lactose-free varieties, may contain added sugar which can take many forms such as fruit puree, honey or cane sugar. Greek yoghurt can contain less total sugar compared to lactose-free yoghurt varieties and you may find that the small amounts of lactose in Greek yoghurt do not cause you any gut discomfort.

Dairy foods don’t have to be eliminated from a person’s diet who is lactose intolerant, rather lactose intake should be adjusted according to tolerance. Spreading dairy intake out over a day, for example, instead of concentrating it in one meal is often better tolerated.

If you suspect you might be intolerant to lactose, it's important to speak with an Accredited Practising Dietitian or experienced health professional before making dietary changes.
