Cheese is one of the first things clients ask me about when they realise dairy is mostly restricted on low FODMAP. “Does that mean all cheese?” is a question I get almost every week. As a certified nutritionist, mozzarella is usually the good news I get to deliver.
The Short Answer
Is mozzarella low FODMAP? Yes, in the right portion. Mozzarella is naturally low in lactose, which makes it one of the more forgiving cheeses on a low FODMAP diet, unlike soft cheeses such as ricotta or cottage cheese.
The Monash University FODMAP app lists mozzarella as low FODMAP in servings up to about 40 g (roughly 1.5 oz); that’s a reasonable amount for a pizza topping, a caprese salad, or a sandwich.

Why Is Mozzarella Lower in FODMAPs Than Other Cheeses?
The FODMAP content of cheese comes down to how much lactose remains after processing. Harder, more aged cheeses generally have less lactose because more of it is removed during the cheesemaking process — the whey (which carries most of the lactose) separates out, and aging breaks down what’s left even further.
Mozzarella falls into a middle category: it’s a fresh cheese, but the process still removes enough lactose to keep it low FODMAP in moderate portions, unlike truly soft, high-moisture cheeses like ricotta or cream cheese, which retain much more lactose.

How to Enjoy Mozzarella on a Low FODMAP Diet
- Caprese salad: fresh mozzarella, tomato, basil, and olive oil — a naturally low FODMAP combination in one dish
- On low FODMAP pizza: use a corn tortilla or certified gluten-free crust, low FODMAP marinara, and a moderate portion of mozzarella
- In a wrap or sandwich: pair with the [Low FODMAP Wraps] recipe for an easy lunch
- Melted over roasted vegetables: a simple way to add flavour without needing garlic or onion
Stick to about 40 g per serving (roughly the size of a small handful of shredded cheese or a few thin slices) to stay within the low FODMAP range confirmed by Monash testing.
What About Lactose-Free Mozzarella?
If you want to eat larger portions without worrying about the 40g limit, lactose-free mozzarella (where available) removes the concern entirely, since the lactose has already been broken down. It’s not as widely available as lactose-free milk or yogurt, but some speciality grocery stores and health food shops carry it.
FAQs
Is fresh mozzarella different from low-moisture mozzarella for FODMAP purposes?
Both are generally considered low FODMAP in similar portions, though fresh mozzarella (the kind packed in water/brine) has slightly higher moisture and lactose content, so sticking to the 40g guideline matters more with fresh mozzarella specifically.
Can I eat mozzarella during the elimination phase?
Yes, mozzarella in appropriate portions is fine during elimination; it’s one of the dairy products you don’t need to fully cut out, unlike milk or soft cheeses.
Is string cheese low FODMAP?
Most string cheese is made from low-moisture mozzarella, which is low FODMAP in standard single-serving portions (typically around 28 g per stick, well under the 40 g threshold).
What cheese should I avoid completely on low FODMAP?
Ricotta, cottage cheese, and cream cheese are the main ones to avoid, since they retain significantly more lactose than harder or more processed cheeses like mozzarella, cheddar, or parmesan.
Final Thoughts
Mozzarella is genuinely good news on a low FODMAP diet, you don’t have to give up pizza night or a caprese salad; you just need to be mindful of portion size. Keep it to around 40 g per serving, and it fits comfortably within the diet.
