What does low-FODMAP actually mean?
What low means per serving, why whole pouches matter, and how a finished meal is checked.
“Low” is about the serving
A food can contain some FODMAPs and still count as low-FODMAP at a particular serving size. Monash compares laboratory measurements for that amount with research-based cut-offs. [1]
A larger portion can change the rating. Individual tolerance also varies. [6]
Ingredients and amounts work together
The recipe sets the starting point. Ingredients such as onion or garlic powder can contribute fructans, while the quantities used determine how much goes into the meal. [4]
An ingredient list helps identify possible sources, but cannot establish the finished food’s FODMAP content. Ingredient selection and processing can change the result. [2]
Think in whole pouches
If a pouch is labelled two servings and you eat it all, you have eaten two label servings.
Where a tested low-FODMAP serving is provided, compare it with the amount you’ll actually eat. A result for one serving does not automatically cover a whole two-serving pouch. [1] [4]
One pouch. One meal. That’s our goal.
We’re developing Gentle Terrain around the whole pouch as the intended low-FODMAP serving, so you won’t need to split a backpacking meal or do serving-size calculations on the trail.
How a finished product is verified
Laboratory analysis measures the product’s FODMAP content. For Monash product certification, samples are tested as consumed, including any required preparation. That includes dehydrated meals. [3]
A Monash-certified ingredient does not make the finished meal certified or guarantee that it meets the criteria. The product needs its own assessment and laboratory testing. [3]
For certified packaged products, the recommended serving is part of the claim. Check that amount alongside the badge. [4]
A meal and the wider diet
Choosing a low-FODMAP meal does not mean starting a full restrictive diet. The clinical approach for IBS is a separate process of temporary restriction, reintroduction and personalization, with dietitian guidance. [5]
