If you’re a fan of Vietnamese cuisine, you’ve probably heard of pho. This soup, typically made with rice noodles, meat, and herbs, has become increasingly popular in recent years. However, for some people, eating pho can lead to unpleasant digestive symptoms, including diarrhea. In this article, we’ll explore why does pho give me diarrhea and provide tips on how to prevent it.
What is Pho?
Before we dive into the causes of pho-induced diarrhea, let’s briefly discuss what pho is. Pho is a Vietnamese noodle soup that typically consists of broth, rice noodles, meat (usually beef or chicken), and herbs. The broth is typically made by simmering bones (usually beef or chicken) for several hours, which releases the flavors and nutrients from the bones.
Who is Affected by Pho-Induced Diarrhea?

Not everyone who eats pho will experience diarrhea. However, some people are more prone to digestive issues than others. For example, those with sensitive stomachs may be more likely to experience diarrhea after eating pho. Additionally, if the pho is contaminated with bacteria or other pathogens, it can cause diarrhea in anyone who consumes it.
Why Does Pho Give Me Diarrhea?

There are several possible causes of pho-induced diarrhea:
1. Food Sensitivities
Some people may have sensitivities or intolerances to certain ingredients in pho, such as gluten or MSG. If your body is unable to properly digest these ingredients, it can lead to digestive issues like diarrhea.
2. Bacterial Contamination
If the pho is contaminated with bacteria, it can cause food poisoning, which often leads to diarrhea. Bacteria like E. coli and Salmonella are common culprits of food poisoning and can be found in contaminated food.
3. Spicy Broth
Pho broth is often seasoned with spices like ginger, cinnamon, and star anise, which can irritate the digestive system and cause diarrhea in some people.
How to Prevent Pho-Induced Diarrhea?

Fortunately, there are several steps you can take to prevent pho-induced diarrhea:
1. Choose High-Quality Ingredients
When making pho at home or selecting a restaurant, choose high-quality ingredients to decrease the likelihood of bacterial contamination. Look for restaurants that use fresh ingredients and clean cooking practices.
2. Ask for No MSG
If you have a sensitivity to MSG, ask the restaurant if they use it in their pho broth. If they do, ask if they can make your pho without MSG.
3. Start with Smaller Portions
If you’re new to eating pho or have a sensitive stomach, start with smaller portions to see how your body reacts. This can help you avoid overeating and digestive discomfort.
4. Avoid Spicy Broth
If you know that spicy foods upset your stomach, opt for a milder broth when ordering pho. Alternatively, you can ask the restaurant to make your broth less spicy.
