Quick Answer: Is Cheese Low FODMAP?
It depends on the cheese. Hard, aged cheeses are naturally low in lactose because bacteria consume it during aging. Soft, fresh cheeses retain more lactose and are high FODMAP.
Evidence-Based: Monash University has tested most common cheeses. Aging = lower lactose = safer for IBS.

Why Aged Cheese Is Safe
During aging, bacteria break down lactose — the FODMAP culprit in dairy — into lactic acid. A hard cheddar aged 12+ months contains less than 0.5g lactose per serve, well below the IBS trigger threshold.

FAQ
Is lactose-free cheese always safe? Yes — lactose-free versions of any cheese are green.
Can I have processed cheese slices? Usually yes at 1–2 slices, but check for milk solids and inulin.
Does cooking change lactose? No — heat does not break down lactose.
