What You Need to Know
Pesto Sauce typically contains Parmesan cheese, which is a dairy product and therefore not suitable for those with lactose intolerance. Lactose, the sugar found in milk, can cause digestive issues for individuals who are unable to properly digest it, making traditional pesto incompatible with a lactose-free diet.
For those on a lactose-free diet, it's important to seek alternatives to traditional pesto. Consider making homemade pesto using lactose-free cheese or nutritional yeast to achieve a similar flavor profile without the dairy. Always check labels on store-bought products to ensure they are labeled as lactose-free or dairy-free.
