If you’re following a low FODMAP diet to manage symptoms of Irritable Bowel Syndrome, you may be wondering: is celeriac low FODMAP? Also known as celery root, celeriac is a nutritious root vegetable often used in soups, purées, and salads. But its compatibility with a low FODMAP diet depends on portion size and its carbohydrate composition.
In this article, we’ll explore the scientific evidence, safe serving sizes, and practical tips to help you decide whether celeriac fits into your diet.
What Is Celeriac?
Celeriac (Apium graveolens var. rapaceum) is a root vegetable closely related to celery. It has a mild, earthy flavor and is rich in:
- Dietary fiber
- Vitamin C
- Potassium
- Antioxidants
Despite its health benefits, its FODMAP content determines whether it is suitable for people with sensitive digestion.
Is Celeriac Low FODMAP? (Short Answer)
Yes—celeriac is low FODMAP in small portions.
However, it contains mannitol, a type of polyol (one of the FODMAP groups). This means:
- ✅ Low FODMAP at small servings
- ❌ High FODMAP at larger servings
Scientific Explanation: Why Portion Size Matters
Celeriac contains polyols (specifically mannitol), which are poorly absorbed in the small intestine. According to research from Monash University, polyols can:
- Draw water into the intestines
- Be fermented by gut bacteria
- Produce gas and bloating
This is why portion control is essential when consuming celeriac on a low FODMAP diet.
Recommended Low FODMAP Serving Size
Based on current laboratory testing:
- ✅ Safe serving: ~75 grams (about ½ cup chopped)
- ⚠️ Moderate risk: 100–150 grams
- ❌ High FODMAP: larger portions due to increased mannitol content
Always start with a small portion and monitor your tolerance.
Nutritional Benefits of Celeriac
Even with portion limits, celeriac offers several health benefits:
- Supports immune function (vitamin C)
- Aids digestion (fiber, in tolerated amounts)
- Low in calories (helpful for weight management)
- Contains antioxidants that may reduce inflammation
How to Eat Celeriac on a Low FODMAP Diet
Here are safe and practical ways to include celeriac:
🥗 Low FODMAP Meal Ideas
- Mashed celeriac with lactose-free butter
- Roasted celeriac cubes with olive oil
- Celeriac soup (without onion or garlic)

💡 Cooking Tips
- Combine with other low FODMAP vegetables like carrots or zucchini
- Avoid pairing with high FODMAP ingredients (e.g., onion, garlic)
- Use herbs and spices for flavor instead
When Should You Avoid Celeriac?
You may need to limit or avoid celeriac if:
- You are in the strict elimination phase of the low FODMAP diet
- You are sensitive to polyols (mannitol)
- You notice symptoms like bloating or gas after eating it
Conclusion
So, is celeriac low FODMAP?
👉 Yes, but only in controlled portions.
Celeriac can be part of a balanced low FODMAP diet when consumed in moderation (around 75g). Because it contains mannitol, eating too much can trigger digestive symptoms, especially for individuals with Irritable Bowel Syndrome.
Summary
- Celeriac is low FODMAP in small servings (~75g)
- It contains mannitol, a polyol that can cause symptoms in larger amounts
- Portion control is key to avoiding digestive discomfort
- It can be safely included in meals when combined with other low FODMAP foods
FAQ: Is Celeriac Low FODMAP?
