Irish startup's pocket-sized gadget shows you what food is bad for your gut

The AIRE device made by FoodMarble measures hydrogen in the breath, to tell users which foods trigger their digestion problems.
There is no cure, although it can be managed with lifestyle and dietary changes. But discovering which foods trigger a bad reaction for individuals can be a long and painstaking process. It's expensive too — a 2019 study of six European countries found that it cost healthcare systems between €937 ($1,087) and €2,108 ($2,445) per patient per year.
That's why Irish engineers Aonghus Shortt and Peter Harte founded FoodMarble, a startup that has invented portable devices, measuring just 5 centimeters squared, which test the hydrogen levels in a person's breath -- a key signal for digestive disorders.
