Yogurt (regular)
Dairy · Yogurt
Regular yoghurt never reaches green in our data. A quarter cup, 60 g, is rated amber on 0.9 g of lactose, and three quarters of a cup, 200 g, is rated red on 3 g. Because a single shop-bought pot holds roughly that larger amount, the ordinary breakfast portion is the red one.

Is yogurt (regular) low FODMAP?
Lactose is the only group recorded here, and nothing in the making of yoghurt takes it away. The milk is cultured in the pot it is sold in: no whey is drained off, so the sugar dissolved in that whey stays exactly where it started. Fermentation does eat into it, which is why two tablespoons of regular milk carry the same 0.9 g that four tablespoons of yoghurt do. Straining is what closes the gap properly, and Greek yoghurt rates green at 100 g on 0.6 g.
Yogurt (regular) and IBS: what to know
Amber is a band rather than a ban, and where you land in it depends on how much lactase your own gut still makes; a quarter cup is a dollop, not a bowl, and plenty of people manage that comfortably. Flavoured tubs are where a second problem creeps in, because fruit purée, dried fruit and honey, which is rated red on its own, pile fructose and fructans on top of the milk sugar already in the pot. Plain natural yoghurt keeps you dealing with one group instead of three.
Gut-friendly ways to eat yogurt (regular)
Lactose-free yoghurt changes the arithmetic rather than the meal: it is the same cultured dairy with the enzyme already added, it rates green, and a full bowl of it stops being a calculation. Coconut yoghurt rates green too if you would rather leave dairy alone. Staying with the real thing means demoting it: use the tested quarter cup as a garnish, spooned over berries, stirred into a curry off the heat, or thinned with lemon into a dressing, instead of as the base of a breakfast.
Frequently asked questions
Can I eat regular yoghurt with IBS?
In small amounts, with attention. The smallest tested serve, a quarter cup, is already rated amber, so even a modest dollop is a judgement call rather than a free pass, and how it goes depends on how much lactose you personally handle. Measuring it into a bowl beats eating from the pot, where the portion decides itself.
Why is Greek yoghurt low FODMAP when regular yoghurt is not?
Because of what leaves during straining. Greek yoghurt is hung or spun until much of the watery whey runs off, and the milk sugar goes with the liquid. The figures show the gap plainly: 100 g of the Greek kind holds 0.6 g of lactose and rates green, while 60 g of the regular kind holds 0.9 g and is amber. More yoghurt, less sugar.
Is fruit yoghurt low FODMAP?
Our figures describe plain yoghurt, and a fruit tub is plain yoghurt plus whatever is in the base. That usually means purée and added sugars, sometimes honey, and occasionally inulin or chicory root fibre used to thicken low-fat versions, which is a fructan. None of it removes lactose, so a flavoured pot can only add to the total.
Does straining yoghurt at home lower the lactose?
It pushes in the right direction, since the whey you pour off is where the milk sugar sits, and that is precisely what gives Greek yoghurt its lower figure. What you cannot do is put a number on your own result: the data covers yoghurt as sold, not as hung in a cloth overnight. Treat home-strained yoghurt as probably lower and still worth measuring.
