After you scan a barcode, there is quite a lot happening behind the scenes before you get your result. This post takes you through our methodology for estimating the FODMAP content of a product and provides further context on our decision-making process.
Basic Methodology for Green, Yellow & Red Products
The Low FODMAP Diet aims to restrict various foods known to cause digestive issues in certain people. The diet is not strictly eat-this-not-that, but rather focuses on serving sizes. Foods are lab tested one by one and classified as either low, moderate, or high based on FODMAP load.
Spoonful uses the same idea to classify grocery products that have multiple foods in the ingredient list.
- Green icon products are considered compliant as they contain only foods that are likely low FODMAP at 1 serving.
- Red icon products are considered not compliant as they contain foods that are likely high FODMAP at 1 serving.
- Yellow icon products are considered potentially compliant as they contain foods that may be low or high FODMAP depending on serving size, and a few other factors.
Learn how to classify yellow products as low or high FODMAP by using Spoonful in conjunction with the Monash app.
Products with moderate or high FODMAP ingredients that are still Low FODMAP
Foods like ketchup, sriracha and almondmilk have all tested low FODMAP at manageable serving sizes despite having high FODMAP ingredients like onion, garlic and almond. This is because these trigger ingredients are used in such small quantities per serving that the product as a whole is considered safe.
Over time, we have trained the Spoonful App to identify these edge cases and override the initial yellow or red classification.
Moderate or high FODMAP products with only low FODMAP ingredients
It makes sense that products like almondmilk are considered low FODMAP – most almondmilks contain only 3-5 almonds per serving. But how can a product be considered high FODMAP if its comprised of only low-FODMAP ingredients?
Let’s look at orange juice. While a single serving of oranges is low FODMAP, orange juice contains lots of oranges and can oftentimes be high in fructose depending on the processing. Fresh orange juice has a lower FODMAP load than reconstituted juice, but we still recommend limiting your intake.
Lactose free milk and low FODMAP cheeses
As many who follow the diet know, “milk” in plain form is high FODMAP, but there are a few exceptions. When milk appears on a product labeled “lactose free” (containing the lactase enzymes), we do not flag it.
There are also a number of low FODMAP cheeses that list milk as an ingredient. This is because the lactose content in milk is often reduced to safe FODMAP levels during the cheese-making process. We account for this in the app by not flagging milk if it is listed on a low FODMAP cheese label. This means you can find plenty of great cheeses to choose from on the Discover feed!
Moderate or High FODMAP Ingredients that Follow 2% or Less Statements
Remember, the low FODMAP diet does not deal in absolutes. This means that most ingredients listed after a “Contains 2% of Less” statement are present in a small enough quantity to be considered low FODMAP.
This in mind, we do not flag high or moderate FODMAP ingredients listed after 2% or less statements. The only exceptions to this rule are garlic, onion, chicory, and inulin — these ingredients can trigger IBS symptoms even when present in small quantities.
Helping you make practical, informed decisions
No matter what, our goal is to help you, the low-FODMAP eater, find tasty, compliant food wherever you shop. And while we recognize that no product is 100% safe unless lab tested, we must contend with the reality that there are simply not enough lab-certified products in our supermarkets.
As eaters, we must also contend with the highly nuanced and ever-changing nature of the low-FODMAP diet, which is why Spoonful is constantly updating our trigger list. This, and all of our product pursuits, is to make sure you feel confident, supported, and in control as you move through the diet.
