Miso is a traditional seasoning used in Japanese cuisine. Since the broth is clear, many people wonder, if you can have miso soup before colonoscopy. After all, it is formed by the combination of two fermentation processes. The first fermentation results in the production of koji. This is then mixed with fermented soya beans. Miso soup is a Japanese soup made from miso and is often served with sushi and rice dishes.
If your miso soup is clear and plain – without tofu, meat cuts, vegetables, noodles, or any other solid complements – you can enjoy a delicious bowl of miso soup on a clear liquid diet.
Miso Soup Before Colonoscopy: Why Doctors May or May Not Recommend It
Doctors may recommend miso soup on a clear liquid diet because it is very nutritious and has incredible health benefits, including:
- It is rich in vitamins, minerals, and probiotics
- It has been found to reduce the risk of developing hepatocellular cancer
- It has anti-inflammatory properties

On the other hand, miso soup may not be recommended by a doctor because of some of its less palatable properties, such as:
- Its high sodium content can increase blood pressure if taken in excess
- Its ability to cause allergic reactions. If you are allergic to soya beans, you should avoid miso soup.
- Commercially sold miso soup tends to contain many solid particles, making it unsuitable for consumption on a clear liquid diet. A solution to this would be to prepare your bowl of miso soup yourself following the clear liquid diet standards or to strain it before consumption.

Clear Liquid Alternatives to Miso Soup Before Colonoscopy
Some safe alternatives for miso soup on a clear liquid diet include:
Clear Broth: Chicken, beef, or vegetable broth is an excellent alternative. However, you have to ensure it contains no solid particles.
Gelatin: Plain gelatin desserts like Jell-O can be consumed if they do not have added fruit cuts or artificial coloring.
Popsicles: As long as there are no solid particles, you can safely enjoy popsicles.
Clear Juices: Good options are apple juice, white grape juice, and cranberry juice.
Tea and Coffee: Both beverages are acceptable as long as they are served without milk or cream.
Sports Drinks: Sports drinks can energize you and maintain your electrolyte balance.

Conclusion
In conclusion, miso soup can be a dicey food option on a clear fluid diet. If you choose to include it, ensure it is free of solid food components. However, if you are uncertain, you can opt for safer alternatives. Most importantly, your doctor’s advice is vital in making the right dietary decisions.
