The inclusion of this information should be helpful to people with iron deficiency, and haemochromatosis (the build up of iron, or 'iron overload').

Iron deficiency anaemia is extremely common and can cause a great number of long-term health issues for people suffering from it.

The World Health Organization has said that anaemia is a serious global public health problem that effects 42% of children less than 5 years of age and 40% of pregnant women worldwide.

It can be hard to know if you are getting sufficient iron in your diet, especially if you are a vegetarian. Labelling should help that and could reduce reliance on supplements, often prescribed by the NHS.

People with haemochromatosis could also benefit.
