Are Radishes Low FODMAP? Radishes are a root vegetable that have been around for many, many years. They’re pretty easy to grow, so they’re often part of vegetable plots, or children’s gardens. They also make a good companion crop, as the smell deters some insect pests. They grow well with cucumbers, chervil, peas, lettuce, and nasturtiums. They make a fantastic addition to a salad, but are radishes low FODMAP?


Yes, they are. The Monash University has tested radish, and found it to be low FODMAP in a single serve of two radishes. FODMAP Friendly has also tested radish, and found that they are low FODMAP. A serve is 40 grams, which is roughly equivalent to two radishes.


What To Do With Radishes?

Radishes are actually a really good substitute for onion when you’re following a low FODMAP diet. If you’re buying radishes, then there’s three main varieties - Red Globe, White Icicle or Asian radishes, but if you’re growing them yourself, then there’s many more types that you could use. When you’re buying your radishes, look for bunches with the leaves still on, as they will be freshest, and you can use the leaves to gauge the radish. Look for healthy leaves. Early radishes, like the White Icicle variety, will have a milder flavor.
