Research on the FODMAP content of orange tomatoes is limited. However, most varieties of fresh tomatoes, including common red tomatoes, are considered low-FODMAP in small to moderate servings (around 65-75 grams, or approximately half a medium tomato). Nebraska tomatoes, which are yellow, are low-FODMAP in servings up to 100 g (11). Orange tomatoes likely follow a similar pattern, but it’s important to be mindful of portion sizes.
