Yes, Oats are Low FODMAP.
Oats can be low FODMAP, depending on your serving size, the type of oats, where in the world you are, and if they’re raw or cooked oats.
Rolled oats are also known as whole oats, or old fashioned oats. They’re made by steaming and rolling oat groats into flakes. They are quite quick to cook, as the rolling process partially cooks them. They may be known by different names in different countries, and different countries may have their own rolling methods, which can slightly change the oats.
Traditional rolled oats are low FODMAP in a single serve of 1/2 cup of uncooked oats, as tested by the Monash University. However, a serving of 3/4 cups of uncooked rolled oats is high FODMAP.

Oat groats are the whole oat. They take much longer to cook than other types of oat. They are low FODMAP at one serve of 1/4 cup, and two serves at 1/2 cup, but they become moderate FODMAP in four servings at one cup.
