The question of whether chickpeas can be included in a low FODMAP diet is a common one, and the answer lies in a specific preparation method and careful portion control. For individuals with Irritable Bowel Syndrome (IBS) or other digestive sensitivities, managing FODMAP intake is crucial, but it doesn't always mean eliminating favorite foods entirely. By understanding the science behind how FODMAPs are removed from chickpeas and adhering to guidelines from trusted sources like Monash University, you can safely enjoy this versatile legume. This guide explains everything you need to know, from the difference between canned and dried varieties to the right way to prepare them for optimal digestive comfort.
The Crucial Difference: Canned vs. Dried
The most important distinction to understand is between canned and dried chickpeas. Dried, uncooked chickpeas are inherently high in the FODMAPs known as galacto-oligosaccharides (GOS) and fructans, and consuming them is likely to trigger symptoms. The reason canned chickpeas are different is due to their processing. FODMAPs are water-soluble carbohydrates, meaning they dissolve in water. During the canning process, the chickpeas are stored in liquid for an extended period, allowing a significant amount of these FODMAPs to leach out of the legumes and into the brine. This makes the chickpeas themselves lower in FODMAPs by the time they reach the store shelf. In contrast, cooking dried chickpeas from scratch, even with soaking, does not sufficiently reduce their FODMAP content to a safe level for the elimination phase.
Preparing Canned Chickpeas for Low FODMAP
To ensure your canned chickpeas are as low FODMAP as possible, you must follow a two-step process: draining and rinsing.
- Draining: First, pour the entire can of chickpeas and their liquid into a colander or fine-mesh sieve. This removes the highly concentrated, FODMAP-rich brine.
- Rinsing: Next, rinse the drained chickpeas thoroughly under cool, running water for at least 30 seconds. This washes away any remaining FODMAPs from the surface of the beans. It is crucial not to skip this step, and to discard all the canning liquid.
Once prepared this way, the chickpeas are ready for use in your low FODMAP meal. It is also important to remember not to reuse the canning liquid in your cooking.
Portion Control: The Golden Rule
Even with proper preparation, portion size is non-negotiable for keeping canned chickpeas within the low FODMAP range. A safe, low FODMAP serving size is approximately 1/4 cup (40-42g) of rinsed and drained canned chickpeas per meal, according to Monash University. Exceeding this amount can increase the total GOS load and may trigger symptoms like bloating and gas. It is also essential to be mindful of FODMAP stacking, where you combine multiple foods that are individually low FODMAP but collectively contribute to a high FODMAP load.
Chickpea Flour and Hummus: Proceed with Caution
Recipes that use chickpeas can be a bit trickier.
Chickpea Flour
Chickpea flour, or besan, is made from ground dried chickpeas and is considered high FODMAP. Since the processing doesn't involve water to leach out the FODMAPs, it should be avoided during the elimination phase.
Hummus
Store-bought hummus is almost always high FODMAP due to large quantities of chickpeas, as well as high FODMAP ingredients like garlic. To enjoy hummus, you must make it yourself using a low FODMAP portion of canned, rinsed chickpeas. A low FODMAP serving of homemade hummus would be much smaller than the 1/4 cup of whole chickpeas. You can substitute garlic with garlic-infused olive oil for flavor.
Comparison Table: Canned vs. Dried Chickpeas on a Low FODMAP Diet
| Feature | Canned Chickpeas (Rinsed & Drained) | Dried Chickpeas (Soaked & Cooked) |
|---|---|---|
| FODMAP Content | Low FODMAP in small portions (approx. 1/4 cup). | High FODMAP regardless of preparation. |
| FODMAP Type | GOS, but significantly reduced by canning. | High concentration of GOS and fructans. |
| Preparation | Requires simple rinsing and draining. | Requires soaking overnight and thorough cooking. |
| Digestive Impact | Well-tolerated in controlled amounts. | Likely to cause gas, bloating, and other IBS symptoms. |
| Convenience | Highly convenient and ready to use. | Time-consuming process. |
Safe and Flavorful Chickpea Alternatives
For those who are very sensitive or want to avoid chickpeas entirely, there are several low FODMAP alternatives that can provide a similar texture or nutritional profile.
- For Salads and Snacks: Use canned, rinsed lentils or roasted pumpkin seeds for a crunchy texture.
- For Curries and Stews: Consider tempeh, quinoa, or diced firm tofu, all of which are low FODMAP.
- For Hummus-Style Dips: Try a homemade dip using canned lentils, or a blended vegetable puree with garlic-infused olive oil.
Conclusion: Enjoy Chickpeas with Moderation and Care
To summarize, the answer to "Are chickpeas okay on low FODMAP?" is a qualified yes, but only for canned varieties, and strict attention to portion size is required. By rinsing and draining canned chickpeas to remove the water-soluble FODMAPs, and limiting your intake to a Monash-approved portion of about 1/4 cup, you can incorporate them into your diet without triggering symptoms. Remember that dried chickpeas and chickpea flour are high in FODMAPs and should be avoided during the elimination phase. By following these guidelines and listening to your body, you can safely enjoy the nutritional benefits of chickpeas while managing your digestive health.

Your Gut-Friendly Chickpea Guide
- Canned is Low FODMAP: A small portion of canned, rinsed chickpeas (approx. 1/4 cup or 42g) is low FODMAP due to the canning liquid leaching out the carbs.
- Dried are High FODMAP: Dried chickpeas are high in GOS and fructans and are not suitable for the elimination phase, even after soaking and cooking.
- Rinsing is Essential: Always drain and thoroughly rinse canned chickpeas to wash away residual FODMAPs in the brine.
- Watch Your Portions: Exceeding the recommended 1/4 cup serving of canned chickpeas can lead to a moderate or high FODMAP load.
- Avoid Chickpea Flour: Chickpea flour is high FODMAP and should be avoided during the elimination phase.
- DIY Hummus: Make your own low FODMAP hummus using canned, rinsed chickpeas and garlic-infused oil instead of relying on store-bought versions.
