How much Heinz ketchup is low in FODMAP?

7 min read

According to Monash University, the pioneer in FODMAP research, a very small portion of standard U.S. Heinz ketchup—just one sachet or about two teaspoons (13g)—is considered a low-FODMAP serving. While this small amount can be tolerated by many, exceeding this portion size can introduce high levels of fructans and fructose from ingredients like onion powder and high-fructose corn syrup.

Quick Summary

Standard Heinz ketchup is low FODMAP in very small portions, about 13 grams, due to ingredients like onion powder and high-fructose corn syrup becoming problematic in larger amounts. Certified low-FODMAP ketchup alternatives exist, and careful portion control is essential.

Key Points

  • Small Serving is Low FODMAP: A 13g serving (about two teaspoons) of standard U.S. Heinz ketchup is low in FODMAPs, according to Monash University research.

  • Portion Size Matters: Increasing the serving of Heinz ketchup to 26g (four teaspoons) makes it high in fructans, which can trigger IBS symptoms.

  • Check for Onion and HFCS: Conventional ketchups are problematic due to high-fructose corn syrup (HFCS) and onion powder, both containing FODMAPs.

  • Alternatives are Available: Certified low FODMAP ketchup brands like Fody Foods offer safe, onion-and-garlic-free alternatives for larger portions.

  • Homemade is an Option: Making your own ketchup allows for complete control over ingredients, ensuring it is low in FODMAPs.

  • Individual Tolerance Varies: Personal tolerance to small amounts of ketchup varies, and a controlled reintroduction phase is necessary to determine individual thresholds.

The low FODMAP diet is a specialized eating plan proven to help manage symptoms of Irritable Bowel Syndrome (IBS). It involves restricting fermentable carbohydrates (FODMAPs) that can cause gas, bloating, and digestive discomfort. For many, condiments are a minefield, with ketchup being a common source of confusion. The truth is, whether you can have Heinz ketchup on a low FODMAP diet depends on two crucial factors: the specific type of ketchup and, most importantly, the portion size.

Understanding FODMAPs in Standard Ketchup

Conventional ketchups, including the classic American Heinz formula, often contain ingredients that are high in FODMAPs when consumed in larger quantities. Two ingredients, in particular, are the main culprits:

High-Fructose Corn Syrup (HFCS)

HFCS is a common sweetener used in many processed foods and drinks in the United States. Fructose is a type of monosaccharide, the 'M' in FODMAP, and when consumed in excess of glucose, it can be poorly absorbed and lead to digestive issues in sensitive individuals. While classic Heinz ketchup contains HFCS, the small portion size tested by Monash University mitigates the fructose load.

Onion Powder

Onion powder is another standard ingredient in traditional ketchup, adding a savory depth of flavor. Onion contains fructans, which are oligosaccharides (the 'O' in FODMAP). Fructans are a type of fermentable fiber that can cause significant digestive distress for those with IBS. The concentration of onion powder means that even a small amount adds FODMAPs, but again, the quantity matters greatly.

How Much Heinz Ketchup Is Low in FODMAP?

Monash University, the globally recognized authority on the low FODMAP diet, has tested ketchup, and the results provide clear guidance on safe serving sizes. Their findings show that different formulations and even geographical versions of ketchup have different FODMAP levels. It's not a 'no' but a 'know your portion' situation.

Monash University Findings for Ketchup

  • USA Ketchup (with and without HFCS): Monash testing found that a 13g serving (about 2 teaspoons or one standard sachet) is considered low FODMAP. At double that amount, or 26g (two sachets), it becomes high in fructans and should be avoided during the elimination phase. This confirms that the issue is primarily one of quantity, not the presence of HFCS itself in a small dose.
  • Australian Tomato Sauce: Interestingly, Monash testing on Australian versions found that a 13g serve (two smaller sachets) was low FODMAP, but became high in fructans at 26g.

Heinz Options: Classic vs. Simply

Heinz offers several products, and while the classic variety contains high-fructose corn syrup and onion powder, some consumers look to the "Simply Heinz" variant as a potential low-FODMAP option. While "Simply Heinz" uses cane sugar instead of HFCS, it's crucial to check the label for onion and garlic powder, which are often still included. Without specific Monash testing on this exact formula, it's safer to assume a similar, very conservative portion size is necessary due to the presence of fructans.

Comparison of Ketchup Options for a Low FODMAP Diet

Feature Standard Heinz (USA) Simply Heinz (USA) Certified Low FODMAP Ketchup (e.g., Fody)
Sweetener High-Fructose Corn Syrup Cane Sugar Cane Sugar, Maple Syrup
Onion/Garlic Contains Onion Powder Contains Onion Powder No Onion/Garlic
Low FODMAP Serve 13g (approx. 2 teaspoons) Likely small, depends on onion powder content Up to 15g, certified safe
High FODMAP Risk High levels of fructans at 26g Contains fructans from onion powder Very low

Low FODMAP Ketchup Alternatives

For those who need more than a tiny dab of ketchup or prefer to avoid the gamble, several excellent low FODMAP alternatives exist.

  • Certified Brands: Companies like Fody Foods and Bay's Kitchen offer ketchups specifically designed for the low FODMAP diet, formulated without onion or garlic powder. These are a safe choice for larger portions during the elimination phase.
  • Homemade Versions: Making your own ketchup from scratch gives you complete control over the ingredients. Recipes can substitute garlic-infused oil for garlic powder and omit onion, using spices like paprika, mustard powder, and allspice for flavor. A great starting point would be to follow a simple recipe that avoids onion and garlic altogether, such as one might find on a reputable low FODMAP recipe blog.

Practical Tips for Using Ketchup on a Low FODMAP Diet

Here are some actionable tips to help you navigate ketchup while managing your IBS symptoms:

  • Respect the Portion Size: Stick strictly to the recommended 13g (about 2 teaspoons) serving size for regular Heinz ketchup during the elimination phase. Do not add more, and be mindful of other FODMAPs in your meal, as stacking can cause problems.
  • Check Ingredient Lists: Always read labels carefully, especially for other brands. Look for hidden onion, garlic, or high-fructose corn syrup.
  • Consider Alternatives: Don't hesitate to switch to a certified low FODMAP brand or make your own ketchup at home. This allows for larger, more satisfying serving sizes without the risk of triggering symptoms.
  • Test Your Tolerance: After the strict elimination phase, you can test your personal tolerance to larger portions of standard ketchup in a controlled reintroduction phase with a dietitian's guidance. Some individuals may tolerate more, but this is highly personal.

Conclusion

In summary, how much Heinz ketchup is low in FODMAP is a matter of strict portion control, with Monash University confirming that a small 13g serving of standard Heinz is generally safe. However, due to its ingredients, larger quantities quickly become high in fructans and fructose. For those seeking peace of mind or larger portions, the best approach is to either opt for certified low-FODMAP ketchup brands or make your own at home. By understanding the ingredients and adhering to serving size guidelines, you can still enjoy ketchup while successfully managing your IBS symptoms.
