Understanding Beetroot's FODMAP Content
Beetroot is a nutrient-dense root vegetable known for its vibrant color and earthy flavor. However, it contains fructans and galacto-oligosaccharides (GOS), which are types of short-chain carbohydrates categorized as FODMAPs. For many people with Irritable Bowel Syndrome (IBS), consuming large quantities of these fermentable carbohydrates can trigger unpleasant digestive symptoms like bloating, gas, and abdominal pain. The key to including beetroot in a low FODMAP diet lies entirely in understanding and controlling the portion size, as determined by laboratory testing from Monash University, the authoritative source on the topic.
Raw vs. Cooked Beetroot: The Portion Puzzle
For both raw and cooked beetroot, the FODMAP-friendly serving size is quite small. The Monash FODMAP app indicates that a low-FODMAP portion is around 32 grams, which is approximately two thin slices. This limited amount is often impractical for recipes and can be easily exceeded. The high fructan content in larger servings means that a whole beetroot, for instance, would be considered high in FODMAPs and likely to cause symptoms in sensitive individuals.
How Preparation Affects FODMAP Levels
Fortunately, food processing methods can alter the FODMAP content of beetroot, offering more generous serving sizes. This is primarily due to fructans being water-soluble. When cooked or pickled, a significant portion of these carbohydrates can leach out into the surrounding liquid.
Here is a breakdown of how different preparations affect FODMAP content:
- Pickled Beetroot: The process of pickling, especially in vinegar, is highly effective at reducing FODMAPs. The acidic environment helps draw out the water-soluble fructans from the beetroots into the pickling brine. As a result, pickled beetroot is often considered FODMAP-free by Monash University and can be enjoyed in larger portions without concern.
- Canned Beetroot: Similar to pickling, the canning process involves liquid that leaches out some of the fructans. While not as efficient as pickling, it still lowers the FODMAP content significantly compared to fresh beetroot. A low-FODMAP serving size for canned beetroot is around 60 grams, nearly double that of fresh beetroot.
- Boiled Beetroot: Boiling also reduces FODMAPs, as the fructans leach into the water. Peeling the beetroot before boiling can maximize this effect. It's a good practice to discard the boiling water afterward. Roasted beetroot may be slightly higher in FODMAPs than boiled as no liquid is involved to carry away the fructans, so sticking to smaller portions is crucial.
Practical Tips for Including Beetroot in Your Diet
For those following the elimination phase of the low FODMAP diet, stick to the safe portion sizes and preparations. Once you move into the reintroduction phase, you can test your personal tolerance to larger servings of raw or cooked beetroot. Remember, the goal is to eat the least restrictive diet possible while managing symptoms.
Here are some ideas for incorporating beetroot safely:
- Use a small amount of finely grated raw beetroot to add color and crunch to a low FODMAP salad.
- Enjoy pickled beetroot, which has a generous portion size, on sandwiches or as a side dish.
- Make a low FODMAP dip using canned beetroot, lactose-free yogurt, and FODMAP-friendly spices.
- Add a few thin slices of cooked beetroot to a grain bowl or serve with roasted meats.
Comparison of Beetroot Preparation and FODMAP Tolerance
| Preparation Method | Low FODMAP Serving Size | Primary FODMAP | Effect of Processing |
|---|---|---|---|
| Raw/Cooked Beetroot | 32g (approx. 2 thin slices) | Fructans, GOS | None, most FODMAPs retained |
| Canned Beetroot | 60g | Fructans, GOS | Lowered due to leaching into brine |
| Pickled Beetroot | Free (no FODMAPs detected) | Fructans, GOS | Significantly reduced due to leaching into vinegar |
Health Benefits of Beetroot
Despite the FODMAP concerns, beetroot is a very healthy vegetable with numerous benefits. It is rich in essential nutrients, including folate (vitamin B9), manganese, potassium, and vitamin C. The red pigment, betanin, is a powerful antioxidant, and the high content of inorganic nitrates can improve blood flow and lower blood pressure. For those with IBS, finding a way to enjoy beetroot in tolerated amounts can offer these nutritional advantages without triggering symptoms.
Conclusion: Navigating Beetroot on a Low FODMAP Diet
Ultimately, eating beetroot on a low FODMAP diet is achievable by prioritizing portion control and choosing appropriate preparation methods. Fresh, raw, and cooked beetroot must be consumed in very small, controlled amounts. However, canned and especially pickled beetroot offer more flexibility for those who enjoy this vegetable. For anyone following the diet, understanding these differences allows for greater dietary variety and ensures that you can enjoy the nutritional benefits of beetroot while effectively managing IBS symptoms. The Monash University FODMAP app serves as an essential resource for navigating these details accurately and personalizing your diet.
How to Safely Reintroduce Beetroot
After successfully completing the elimination phase, you can test your personal tolerance to different forms of beetroot. During the reintroduction phase, gradually increase your portion size of cooked beetroot while monitoring for symptoms. This will help determine your individual threshold for fructans and allow you to expand your long-term diet without triggering digestive distress.

A note on other beetroot products
While fresh, canned, and pickled forms are well-documented, other products derived from beetroot should be approached with caution. Beetroot juice and extracts are concentrated forms, and because raw beetroot is high in fructans, it is highly likely that these products will also be high in FODMAPs. It is best to avoid these during the elimination phase of the diet and to test them with extreme care during reintroduction. Beetroot leaves, or beet greens, have not been formally tested by Monash University, but due to the high FODMAP content of the root, it's safer to avoid them if you are highly sensitive.
By following these guidelines and paying close attention to your body's response, you can successfully include beetroot in your low FODMAP journey.
