“Ask Ingrid!” is a free app for iOS and Android in which you can set your own intolerances. The app then shows you foods that you can tolerate or indicates whether a food is suitable for you using a sophisticated traffic light system. The data from “Ask Ingrid!” comes from years of research and statistical evaluations of real people affected. The data includes a large number of variables such as ripeness, processing, location, usual consumption quantity and much more. In cooperation with the University of Innsbruck, we have used a complex algorithm to calculate a tolerance index that rates foods according to the best possible tolerance. We then put all this together in a simple traffic light system that reliably assesses compatibility. But “Ask Ingrid!” can do more.

A symptom and food diary is very important if you think you have an intolerance. It makes it possible to detect food intolerances such as lactose intolerance, fructose intolerance, histamine intolerance or other food intolerances and food allergies. However, it can also be used as a symptom diary for Crohn’s disease or irritable bowel syndrome.

The nutrition and symptom diary is available as a large hardcover book with 188 pages and 28 days to write in, but also as a small pocket book with a pink cover, blue cover or gray cover.
