Does Burrata Trigger IBS?
It depends on the portion, and burrata is stricter than mozzarella. The mozzarella shell is drained and low in lactose, but the stracciatella filling is curd suspended in fresh cream, which puts the lactose back — burrata runs around 1 to 2 grams per 100g, where drained mozzarella is far lower. Monash has never tested burrata, so there is no certified serving. Working from its lactose content, about 30g stays comfortably under the 1g-per-sitting threshold Monash uses for lactose. A whole ball is 100 to 125g and carries several times that.
What Makes Burrata Problematic for IBS
Two things compound. The first is the cream: stracciatella is shredded curd suspended in liquid cream, and cream carries lactose that the draining and stretching of plain mozzarella had removed. The second is the serving format. Burrata is sold as a single ball meant to be cut open at the table, so it is eaten whole by one person — nobody portions a burrata. That makes a food with roughly three times mozzarella's lactose density routinely eaten in three times the quantity, which is how people who tolerate mozzarella without thinking about it react to burrata.
How it works
Lactose is water-soluble, so it leaves with the whey when curd is drained and stretched — that is why plain mozzarella is low in it. Burrata reverses part of that by reintroducing cream into the centre. Lactose needs the brush-border enzyme lactase to be split into glucose and galactose before absorption, and most adults produce less of it than they did as infants. Whatever is not split travels on to the colon, where it draws water in osmotically and is fermented by bacteria into gas. Monash sets the low-FODMAP lactose threshold at under 1 gram per sitting, and a whole ball of burrata clears that.
Common Symptoms
A lactose reaction tends to arrive within a couple of hours and often combines looseness with gas, because the osmotic pull begins in the small intestine while fermentation follows in the colon. Burrata also carries a large fat load delivered all at once, which stimulates the gastrocolic reflex — exaggerated in IBS — and can produce urgency on its own. If a burrata starter went badly, separating the lactose from the fat from the bread it was served on is genuinely difficult.
Portion Thresholds
Safe Portion
Up to about 30g — roughly a quarter of a standard ball
Research Reference
Monash University has not tested or certified burrata, so no official serving exists. It rates mozzarella low-FODMAP at 40g, but burrata is not mozzarella: the cream filling raises lactose to roughly 1-2g per 100g. Against Monash's under-1g-per-sitting lactose threshold, about 30g is the defensible ceiling and a 100-125g ball is well beyond it. Many dietitians advise leaving burrata out of the strict elimination phase altogether.
Practical Tip
Treat it as a shared component, not a portion for one. A quarter of a ball torn over tomatoes and basil for a table of four is a sensible way to eat it. During strict elimination, the common clinical advice is to skip burrata and use plain mozzarella at 40g or feta at 125g instead, then test burrata during the lactose challenge once you know your own threshold. Watch the setting too: burrata arrives with a bread basket, and often with real garlic in the dressing.
Safe Alternatives to Burrata
Related Foods
No. Mozzarella is a low-lactose cheese and one of the safer dairy options for people with IBS. Monash rates 40g (about ½ cup shredded) as low-FODMAP. Fresh mozzarella and pizza mozzarella both fall within this range. The safe portion is smaller than firm aged cheeses like cheddar.
Yes. Ricotta is one of the few high-lactose cheeses — because it is made from whey (not curd), it retains most of the lactose that other cheeses lose during aging. Even 2 tablespoons (30g) is high-FODMAP. Lactose-free ricotta or firm aged cheeses like parmesan are safer.
It depends. Regular cream cheese contains moderate lactose and is considered moderate-FODMAP at standard servings (2 tablespoons / 30g). Smaller portions are usually tolerated. Lactose-free cream cheese is a safe alternative. The high fat content may also worsen symptoms in some IBS patients independently of lactose.
No. Feta cheese is low-FODMAP and safe for IBS at up to 125g per serving. The brining and aging process significantly reduces lactose content compared to fresh cheeses like ricotta or cottage cheese. Feta adds excellent flavor to salads and Mediterranean dishes on a low-FODMAP diet.
No. Parmesan is low FODMAP because the extended aging process (12-36 months) breaks down virtually all lactose. It is one of the safest cheeses for people with IBS and can be enjoyed freely on pasta, salads, and in cooking without FODMAP concerns.
Frequently Asked Questions
Is burrata low-FODMAP?
Only in a small portion, and not on Monash's authority — they have never tested it. Burrata carries roughly 1-2g of lactose per 100g because of the cream filling, so about 30g stays under the under-1g-per-sitting threshold Monash uses for lactose. A standard 100-125g ball is several times that, and many dietitians advise avoiding burrata during strict elimination rather than trying to portion it.
Why is burrata stricter than mozzarella when they look so similar?
Because of what is inside. Plain mozzarella is drained and stretched curd, and draining is what removes lactose. Burrata puts liquid cream back into the centre, which reintroduces some of the lactose that cheesemaking had taken out. Monash rates mozzarella low-FODMAP at 40g; burrata has no such rating and a meaningfully higher lactose density.
Why did burrata upset me when mozzarella never does?
Both the density and the quantity. Burrata carries more lactose per gram than mozzarella, and you almost certainly ate a whole 125g ball — you have probably never eaten 125g of plain mozzarella in one sitting. Add a large fat load arriving at once, which triggers the gastrocolic reflex, and the bread it came with, and there are three plausible contributors.
Can I eat burrata during the elimination phase?
The cautious answer, and the one most dietitians give, is no — leave it out and come back to it during the lactose challenge. If you do want it, a quarter of a ball shared among others is the sensible limit. Plain mozzarella at 40g or feta at 125g gives you something similar with an actual Monash serving behind it.
