Understanding FODMAPs in Ketchup
FODMAPs are a group of short-chain carbohydrates that can cause digestive symptoms in sensitive individuals, particularly those with Irritable Bowel Syndrome (IBS). In ketchup, the primary FODMAP culprits are typically fructans from onion and garlic, and excess fructose from high-fructose corn syrup.
The Problem with Conventional Ketchup
Most major brands of conventional ketchup, such as Heinz, contain high-FODMAP ingredients. These include:
- Onion and Garlic Powder: These are common flavor enhancers in ketchup but are high in fructans, a type of FODMAP.
- High-Fructose Corn Syrup (HFCS): This sweetener can be problematic because the ratio of fructose to glucose is unfavorable, leading to poor absorption in some people.
Even if a brand uses regular sugar instead of HFCS (like Heinz Simply Ketchup), the inclusion of onion powder still makes it a high-FODMAP product.
The Role of Serving Size
For conventional ketchup, serving size is key. Monash University, the pioneer of the low FODMAP diet, has tested ketchup and provides guidance through its app. A very small amount, around a 1-sachet or 2-teaspoon serving, is often considered low FODMAP. This is because the overall FODMAP content is minimal at this quantity. However, for those with severe sensitivities or anyone wanting a larger portion, certified low FODMAP options are necessary to avoid symptoms. FODMAP stacking, where multiple small servings of FODMAPs accumulate throughout the day, can also trigger symptoms.
Low FODMAP Ketchup Brands
Fortunately, there are several brands that have developed low FODMAP ketchup by removing the trigger ingredients. These products are specifically formulated to be gut-friendly and are often certified by organizations like Monash University or Fodmap Friendly.
Fody Foods
Fody Foods is a well-known brand specializing in low FODMAP products. Their ketchup is certified low FODMAP and is free from onion, garlic, and high-fructose corn syrup. It uses simple ingredients and is widely available online and in some grocery stores.
Bay's Kitchen
For those in the UK, Bay's Kitchen offers a low FODMAP tomato ketchup. This product is certified by Fodmap Friendly and is also free from onion and garlic. It provides a rich flavor suitable for various dishes without causing digestive distress.
Making Your Own Low FODMAP Ketchup
Creating your own low FODMAP ketchup at home is a simple and effective way to ensure it meets your dietary needs. This gives you complete control over the ingredients, especially avoiding high-fructose sweeteners and alliums. Here is a basic, easy recipe:

Ketchup Comparison Table
| Feature | Conventional Ketchup (e.g., Heinz) | Certified Low FODMAP Ketchup (e.g., Fody) | Homemade Low FODMAP Ketchup |
|---|---|---|---|
| FODMAP Content | High in fructans (onion/garlic) and excess fructose (HFCS) | Low in fructans and fructose; certified safe | Custom-controlled; can be made entirely low FODMAP |
| Serving Size | Small, around 2 teaspoons, considered low FODMAP | Can be consumed in larger portions | Tolerable in larger quantities with low FODMAP ingredients |
| Ingredients | Contains onion powder, garlic powder, and often HFCS | No onion or garlic; uses low FODMAP sweeteners | Uses infused oils for flavor; custom sugar content |
| Availability | Widely available in most grocery stores | Available online and in specialty or larger supermarkets | Requires home preparation but ingredients are accessible |
| Cost | Generally affordable | Often more expensive due to specialized ingredients | Cost varies but can be economical if making in bulk |
Reading Ketchup Labels
For those who do not have access to certified brands, learning to read labels is crucial. Always check the ingredients list for the following high-FODMAP items:
- Onion powder
- Garlic powder
- High-fructose corn syrup
- Garlic salt
- Onion salt
Infused oils, such as garlic-infused or onion-infused olive oil, are a safe alternative as the FODMAPs are not oil-soluble. Some brands use alternative, low-FODMAP sweeteners like pure maple syrup or cane sugar, which are better tolerated in controlled quantities.
Conclusion
While a very small serving of conventional ketchup might be low enough in FODMAPs to be tolerated, it contains trigger ingredients like onion, garlic, and high-fructose corn syrup that make it a risky choice for those with IBS. For larger portions and peace of mind, the best options are certified low FODMAP brands like Fody Foods and Bay's Kitchen. For complete control and a fresh taste, making a homemade version with a low FODMAP recipe is an excellent and safe alternative. By understanding the ingredients and making informed choices, you can continue to enjoy your favorite foods without digestive discomfort.
