Is ketchup low FODMAP?

Whether it’s on french fries, burgers, or for some people, eggs, ketchup compliments each dish with its tomato-rich flavor. This condiment is a staple food item in many pantries with nearly 97-percent of Americans having ketchup on hand in their kitchen. However, if you are following a low FODMAP lifestyle, you may be wondering if ketchup is safe to eat. Let’s take a better look at ketchup and if you can add it safely to your low FODMAP regimen.

About ketchup

Ketchup is a tomato-based sauce that is typically made from pureed tomatoes, vinegar, salt, pepper, and spices. It’s a low calorie condiment that averages around 15 calories per tablespoon. It also contains no fat and a small amount of vitamins A and C from the tomatoes. However, if you are trying to follow a healthy lifestyle, it’s important to read the label of your ketchup bottle. This is because some ketchup products may have added sugar and excess amounts of salt that can put ketchup in unhealthy territory. The major culprit in ketchup products is high fructose corn syrup, which is pretty much pure sugar.

Ketchup and FODMAPs

Not only is high fructose corn syrup a sugar concern in ketchup products. This ingredient is also an issue when it comes to FODMAP friendliness. This is because high fructose corn syrup is a high FODMAP ingredients. Other high FODMAP ingredients that could be found in ketchup products include onion powder, “spices” which may contain garlic or onion powder, and corn syrup. According to the Monash University app, one packet, or 13 grams of ketchup with onion or garlic, sweetened with sucrose, or table sugar or high fructose corn syrup is considered low FODMAP. Any more than this serving contains higher levels of fructans that could trigger digestive symptoms in some. 

Although less common, some ketchup products may contain honey to sweeten it. Ketchup sweetened with honey, a high FODMAP ingredient, has not been tested by Monash so this type of ketchup product would be off limits.

Take home message
