Cream (sour cream)
Dairy · Cream Butter
Three tablespoons of sour cream, 45 g, rate green on 0.4 g of lactose, and that is a real dollop rather than a token one. The catch sits underneath it. Sour cream lands on nachos, tacos and loaded potato skins, beside onion, garlic and beans, so the plate rather than the cream decides how the meal goes.

Breakdown for 3 tablespoons
Is cream (sour cream) low FODMAP?
Sour cream is cream that has been cultured, and both halves of that description hold the figure down. Starting from cream means starting from the fat, which little lactose travels with, and the bacteria added to thicken it feed on some of what did come across, turning it into the lactic acid you taste as sourness. The tested three tablespoons hold 0.4 g, below the 0.5 g point where lactose begins to count, and no other group appears at all. Pouring cream sits in the same low band at 0.3 g per quarter cup.
Cream (sour cream) and IBS: what to know
The company this stuff keeps is the problem. Nachos are rated red in our guide, and the loaded versions sold by fast food chains are red too, on the strength of the beans, onion and garlic under the cheese rather than the white spoonful on top. Tomato salsa is rated amber for a related reason, since most jars are started with onion. Even the flavour name carries a trap: sour cream and onion crisps are rated red, and no dairy is doing that damage.
Gut-friendly ways to eat cream (sour cream)
Sour cream is the cooling element on a plate that would otherwise want a garlicky sauce, so let it do that job: a dollop on chilli, on a jacket potato, or on soup stirred through once the pan is off the heat, since it splits over direct heat. Whisked with lemon juice, salt and the green tops of spring onions it becomes a dressing that tastes as though aromatics went into it. Three tablespoons will do a shared bowl of dip if you build it out with herbs rather than doubling the cream.
Frequently asked questions
How much sour cream can I have with IBS?
Three tablespoons is the tested amount and it rates green, which is more than most people spoon over a bowl of chilli. Nothing larger has been measured, so a heaped serving straight from a big tub falls outside the data. Because it is fat-rich, richness usually settles your comfort before the milk sugar gets a say.
Can I have sour cream on nachos or tacos?
The cream is the safest thing on the tray. What surrounds it rarely is: refried beans bring GOS, the salsa and the seasoning mix are usually built on onion and garlic, and a shared plate gets eaten without portions. Building your own from plain corn chips, tomato, cheese and a measured dollop keeps every element to something you can name.
Is sour cream and onion flavour low FODMAP?
No, and the name tells you which half is at fault. Those seasonings are made with onion and garlic powder, dehydrated forms that pack concentrated fructans into a small dusting, so a coating on crisps delivers what a slice of the raw vegetable would. The dairy side of the flavour is beside the point. Read packets, dips and seasoning sachets for the powders rather than for the cream.
Is sour cream or cream cheese lower in lactose?
Gram for gram sour cream is the lower of the two: 45 g of it holds 0.4 g of lactose, while 30 g of cream cheese holds 0.3 g, which works out heavier per spoon. Both rate green at their tested amounts, so the difference only starts to matter when one of them is being used by the tub, in a frosting, a dip or a filling.
