1 in 8 people experience frequent digestive disruption. Food is often a factor, but how do you know which foods work for you? When you eat something, it travels through your stomach and into your small intestine for absorption. Anything that isn’t digested continues to your large intestine where fermentation starts to take place. During fermentation the gases methane and hydrogen are produced. Many of us are hydrogen producers but two thirds of us also produce methane. When these gases build up rapidly they can cause IBS-like symptoms. These gases make their way into the bloodstream and move to the lungs. Once in the lungs, methane and hydrogen are exhaled on your breath. By measuring the levels of both these gases on your breath with AIRE 2 you get greater accuracy and you get real-time feedback on whether that food is right for your body.
