FODMAPs stands for Fermentable Oligo-, Di-, Mono-saccharides And Polyols - types of short-chain carbohydrates found in many everyday foods.
For many people, these carbs aren’t absorbed very well in the small intestine. When that happens, they can pull water into the gut and be fermented by bacteria, which may lead to uncomfortable symptoms like bloating, gas, stomach pain, diarrhea, or constipation.

Why breath testing matters for testing food intolerances?
Gas Production
When your gut ferments undigested food, it releases gases like hydrogen and methane. These gases travel through your bloodstream to your lungs and are eventually exhaled.
Fermentation Score
By measuring hydrogen and methane levels, you get real, measurable data about how your gut is responding to different foods.
Breath Testing
It's a non-invasive, fast, and accurate method to understand how well your gut fermented certain foods.
What you think is causing symptoms… might not be the real problem.
Think it's Lactose?
85% of users globally poorly digest Sorbitol
Our global data shows that lactose is actually the least commonly reactive FODMAP in tests — yet it's one of the most eliminated from diets.
🇺🇸 United States: 83% poorly digest Sorbitol
According to our data: despite being widely blamed, lactose has the lowest test positivity among common FODMAPs.
🇮🇪 Ireland: 32% poorly digest
Lactose
Start getting answers with our food intolerance kit
Easily test your tolerance to 4 hard-to-digest food components - lactose, fructose, sorbitol, and inulin - using your FoodMarble device and the Food Intolerance Kit.
We use a data-driven approach to tackle digestive health issues
Measuring hydrogen after eating can help identify patients with chronic gut (GI) symptoms from healthy individuals and may be useful for monitoring patients before, during, and after treatment.
An independent validation showed that AIRE accurately detects lactose malabsorption, with results consistent with clinical methods. This makes AIRE a reliable and convenient alternative for diagnosing lactose issues at home.
AIRE was compared to the top clinical device to evaluate its accuracy in detecting carbohydrate absorption. The comparison showed a perfect match, with 100% diagnostic agreement between the two devices.
FODMAPs are types of carbohydrates that can be hard to digest for some people. They can cause bloating, gas, and discomfort. FoodMarble helps you track how your body responds to them.
What is the Food Intolerance Test Kit?
The Food Intolerance Kit contains four sachets of common fermentable carbohydrates: lactose, fructose, sorbitol, and inulin, that are known to be difficult to digest. When used with a FoodMarble device, which measures your fermentation levels, these tests can help you identify which FODMAPs your body may not be tolerating well and in what quantity.
What is FoodMarble AIRE 2 and how does it work?
FoodMarble AIRE 2 is an advanced digestive breath tester that measures hydrogen and methane gases produced during digestion. These gases are markers of fermentation in the gut, which is common in people with SIBO, IBS or food intolerances. By breathing into the FoodMarble AIRE2, you receive real-time feedback on how your body is responding to specific foods.
Who should consider using the Food Intolerance Kit?
This kit is ideal for individuals with unexplained digestive symptoms like bloating, gas, diarrhea and constipation. And it's also perfect for anyone who is managing SIBO, IBS or food intolerance to better understand their tolerance levels of different FODMAP components.
How long does it take to identify food intolerances with the kit?
You may start seeing trends within a few days. For more reliable insights, we recommend completing all test sachets over a few weeks, and consistently using the AIRE 2 device to track symptoms and results in a longer term for comprehensive understanding.
Can I use the device to test for dairy and lactose intolerance?
Yes! The lactose sachet included in the Food Intolerance Kit enables you to test your body’s response to dairy. AIRE 2 will monitor any fermentation of lactose, providing insights into whether lactose might be causing your symptoms.
Do I need medical supervision to use the Food Intolerance Kit?
The kit is designed for home use and does not require a prescription. However, if you have a complex digestive condition or want to review your results with a professional, it’s possible for us to share your results securely with your doctor, as long as we get your consent. If your doctor is comfortable to proceed, just send an email to clinical@foodmarble.com with contact details for your doctor and we’ll take it from there.
Can I test my reaction to other foods using FoodMarble?
Absolutely yes! With the Custom Challenge feature in the FoodMarble app, you can test your personal response to any specific food. This powerful tool is perfect for exploring how everyday foods impact your digestion. You can easily find this feature in the app and follow the same steps as a regular challenge.
