Tomatoes are a staple ingredient for many recipes. The FODMAP content of tomatoes can vary depending on the variety of the tomato and how they are stored. This means you can still enjoy small serves of tomato on the low FODMAP diet but you need to choose the right option for the meal.

How much is low FODMAP?

The serving size for tomatoes varies depending on the type of tomato and how it is processed:

  • Cherry tomatoes are low FODMAP in 3 tomato serves.
  • Fresh roma tomatoes can be enjoyed in ½ tomato serves or 48g/1.7oz.
  • Fresh vine/truss tomatoes or common tomatoes can be enjoyed in ½ tomato or less serving size.
  • Canned tomato can be enjoyed in 100g or 3.5oz serves.

Larger serves can contain excess fructose or fructans. Make sure you check the Monash University FODMAP Diet App for more information.
