Around 1.2 billion people worldwide suffer from iron deficiency, with women worse affected than men. In Europe, one in five women around the age of 20 suffers from iron deficiency. Typical symptoms include diminished work performance, fatigue, anaemia and headaches. ETH researchers are currently developing a new and highly effective way of fortifying iron into food and drinks.
