Iron deficiency is a global threat mainly affecting women and children. Around 1.2 billion people worldwide suffer from iron deficiency, with women worse affected than men. Incorporating iron-rich foods and using supplements can help boost iron levels but it is tricky, as the iron must be in a form that the body is able to absorb successfully. Iron is also a trace element that can alter the colour, taste and smell of the food it is added to, making it far less appetising.
