Fresh mozzarella is not considered low-FODMAP due to its moderate lactose content, though small portions may be tolerated by some individuals.
Fresh mozzarella contains about 1 gram of lactose per ounce (28g). The Monash University low-FODMAP diet categorizes dairy products containing more than 0.24g lactose per serving as high-FODMAP. Thus, even a small 1-ounce serving exceeds this threshold.
FODMAPs (Fermentable Oligo-, Di-, Mono-saccharides, and Polyols) are short-chain carbohydrates poorly absorbed in the small intestine. Lactose, a disaccharide, falls under the "D" category. Fresh mozzarella's primary FODMAP concern is its lactose content.
Monash University suggests that some individuals may tolerate up to 40g (1.4 oz) of fresh mozzarella without symptoms. However, this varies by individual sensitivity. Those with severe lactose intolerance should avoid it entirely.
For context, a typical serving of fresh mozzarella in caprese salad often exceeds this amount. A standard 2-ounce serving contains twice the lactose content of the suggested limit.
For those following a strict low-FODMAP diet, consider these alternatives:
Many assume all cheeses are high-FODMAP. While fresh mozzarella is high in lactose, aged cheeses typically contain negligible amounts. This distinction is important for those managing IBS through a low-FODMAP diet.
Another misconception is that fresh mozzarella's probiotic benefits outweigh its FODMAP content. While it does contain beneficial bacteria, the lactose content makes it unsuitable for those with lactose intolerance or IBS.
During my time testing low-FODMAP recipes, I discovered that even small portions of fresh mozzarella triggered bloating in sensitive individuals. Switching to lactose-free mozzarella resolved this issue while maintaining the desired flavor profile.
