The Aire, launched by Dublin startup FoodMarble, is a breath-test-based “personal digestive tracker” that claims to be able to find out just what is upsetting your system. Initial tests for lactose intolerance on patients in New Zealand suggest the device can replicate the readings you’d get on a hospital-standard breath-hydrogen analyser, though longer-term trials on a larger cohort remain to be carried out. In my own test on a friend with known lactose intolerance, it gave a positive reading.
The Aire is simple and user-friendly in partnership with its dedicated app, which enables you to track what you eat and analyse how different foods affect your digestion. In addition to lactose intolerance, says FoodMarble, the Aire is able to snout out intolerance to sorbitol, a natural but hard-to-digest sweetener; inulin, a carb found in onion, garlic, bananas and wheat; and fructose, which many people have trouble digesting.
PS: I’ve no idea why the company called itself FoodMarble, as in form – if not function – its product looks more like a tiny cigarette lighter.
