Traditional Vietnamese pho is a comforting and aromatic noodle soup cherished worldwide, but for individuals following a low FODMAP diet, a standard bowl can be a source of digestive upset. The challenge lies in the primary ingredients used to build its rich flavor profile. Fortunately, with a little knowledge, it is possible to enjoy a version of this beloved dish when dining out, or to make an authentic-tasting, low FODMAP version at home.
Why Traditional Pho is High in FODMAPs
Traditional pho relies on a slow-simmered broth packed with flavor from aromatic vegetables and spices. This is where the main high-FODMAP culprits hide. The FODMAPs in these ingredients are water-soluble, meaning they infuse into the broth over the long cooking process, even if the solid pieces are removed before serving.
The Problem with Broth and Aromatics
- Onions and Garlic: The most significant source of FODMAPs in pho broth comes from onions and garlic. These vegetables contain fructans, a type of oligosaccharide that is poorly absorbed by the small intestine and can trigger IBS symptoms in sensitive individuals.
- Cooking Process: During the prolonged simmering of the broth, these fructans are released into the liquid, making a restaurant's large batch of pre-made broth unsuitable for a low FODMAP diet.
High-FODMAP Sauces and Garnishes
While the broth is the primary concern, certain common pho accompaniments also contain high-FODMAP ingredients:
- Hoisin Sauce: This sauce often contains high-fructose corn syrup, garlic, and sometimes wheat, all of which are high in FODMAPs.
- Certain Marinades: Meats might be marinated in high-FODMAP sauces containing garlic or onion powder.
- Mushrooms: Some restaurant pho contains mushrooms like shiitake, which can be high in polyols depending on the type and portion size.
Navigating a Pho Restaurant on a Low FODMAP Diet
Dining out requires clear communication and specific requests. While not every restaurant can accommodate every dietary need, many are willing to make simple modifications. Here is a strategy for success:
- Communicate Clearly: Inform your server that you need a meal made without onion or garlic. Mentioning you have a dietary restriction, rather than just a preference, can emphasize the importance of your request.
- Inquire About the Broth: Ask if the chef can prepare a small, fresh batch of broth for your order, or if they have a pre-made broth that is kept separate and made without onion and garlic. If this is not possible, your safest option is to eat elsewhere or choose a different dish entirely.
- Request Ingredient Substitutions: Ask for low-FODMAP alternatives. Requesting toppings like cilantro, fresh basil, and the green parts of scallions instead of high-FODMAP additions can be a simple adjustment.
- Control Your Condiments: Skip the sauces provided. Instead, bring your own low FODMAP-certified soy sauce or chili oil to add flavor without risk. Many common condiments are high in FODMAPs.
High vs. Low FODMAP Pho Components
Knowing what to swap is essential for creating a safe and delicious low FODMAP meal. The following table compares common high-FODMAP pho ingredients with their low-FODMAP alternatives:
| High FODMAP Ingredients | Low FODMAP Replacements |
|---|---|
| Broth made with onion/garlic | Broth made with garlic-infused oil and the green parts of scallions |
| White and yellow onions | Green part of scallions (chives or spring onion) |
| Hoisin sauce | Low FODMAP-certified soy sauce or a homemade alternative |
| Pre-marinated meats | Plain, unseasoned chicken or beef |
| Mushrooms | Omit or use a low-FODMAP vegetable like carrots |
| Certain flavorings | Flavor with fresh herbs like basil, cilantro, and mint |
Making Your Own Low FODMAP Pho at Home
Creating a low FODMAP pho at home gives you complete control over the ingredients, ensuring a delicious and safe meal. Using garlic-infused oil and the green parts of scallions can deliver a similar aromatic depth without the fructans. For extra flavor, toast spices like star anise and cinnamon sticks before simmering in a homemade, low-FODMAP beef or chicken stock for 20-30 minutes. You can use rice noodles, which are naturally low FODMAP, and top with fresh cilantro, basil, and bean sprouts.
Conclusion
While a restaurant bowl of pho is not typically low FODMAP, enjoying a digestive-friendly version is achievable through careful modifications. The key is understanding the high-FODMAP culprits, particularly the onion and garlic used in traditional broth, and making informed choices or requests. By opting for a safe broth, controlling your condiments, and prioritizing fresh, low-FODMAP toppings, individuals can savor the comforting flavors of pho without the digestive distress. Whether you choose to order a modified version at a restaurant or cook it from scratch at home, a satisfying low FODMAP pho is well within reach.

How to Order Low FODMAP Pho at a Restaurant
Can I eat pho at a restaurant on a low FODMAP diet?
Most restaurant pho is not low FODMAP because the broth is made with onions and garlic. However, with careful communication and specific requests for modifications, a safer meal may be possible.
What are the main high-FODMAP ingredients in pho?
The primary high-FODMAP ingredients are onions and garlic, which are simmered in the broth. Other sources can include hoisin sauce and certain marinades.
How can I request a low-FODMAP broth?
Ask the server if the broth is made with onion and garlic. Inquire if the chef can prepare a smaller, fresh batch of broth using alternative aromatics like garlic-infused oil and the green parts of scallions.
Are pho noodles high or low FODMAP?
Rice noodles, the type used in pho, are generally considered low FODMAP and gluten-free. They are a safe component of the dish.
