How to interpret green, yellow, and red results

Once you’ve scanned a barcode, the resulting product name will be either green, yellow or red. This reflects our best estimate of the product’s FODMAP load at 1 serving. Learn more about how we analyze products.

Green products

If the product name is green, we believe it is low FODMAP at 1 serving based on its mix of ingredients. This does not mean the product is completely void of FODMAPs, or that it wouldn’t be high FODMAP in larger portions. Make sure you’re always checking the label for serving size information and using the the Monash App in conjunction with Spoonful.

Green products with garlic, onion, or other high-FODMAP ingredients

If you’ve scanned a particular condiment or cheese product, you may notice that ingredients like garlic, onion and milk are not flagged. Don’t worry, this is by design!

Certain condiments varieties like ketchup, Worcestershire sauce, and sriracha in addition to certain low-lactose cheeses like parmesan, Swiss, and cheddar have been tested low FODMAP at 1 serving despite having high-FODMAP ingredients. This is because these ingredients are in such low quantities that the product is unlikely to trigger IBS symptoms.

Certified products

If a product has been certified by FODMAP Friendly or Monash, we will indicate that in the text. In addition, FODMAP Friendly certified products will have their icon next to the product photo both in the results modal and Discover feed.

Yellow products

If the product name is yellow, you’ll need to do a bit of detective work before adding it to your basket. Yellow indicates that one of the product’s ingredients can be low or high FODMAP depending on form or serving size. If you’re unsure, tap on the ingredient to learn more.

Form dependent ingredients

Foods like corn, soy, and banana can be low or high FODMAP depending on what form the ingredient takes within the product. For example, ripe bananas have a small low-FODMAP serving size, while unripe or “firm” bananas can be consumed in larger portions. Similarly, corn in vegetable form (kernels, on-the-cob) is higher in FODMAPs than corn flour or ground corn. For these ingredients, you’ll need to make an educated guess based on the product you’re holding.

Serving size dependent ingredients

Foods like almonds, chocolate, and chickpeas can be low or high FODMAP depending on serving size. If you come across one of these ingredients, we recommend checking for serving size information in the Monash App before making a purchase.

Red products

If the product name is red, that food contains an ingredient that is high FODMAP at most serving sizes. We recommend avoiding these products unless they have been lab tested and approved by FODMAP Friendly or Monash.
