Yes.
Just as there are diseases associated with low body iron, an excessive amount of iron can also cause problems. Your body needs iron - for the production of red blood cells and to facilitate the transport of oxygen around your system - but too much of this mineral is toxic.
In addition to causing stomach upset, heartburn and nausea in some people, a high iron intake can also hinder the absorption of zinc, a trace mineral that helps support a healthy immune system by fighting off free radicals and promoting healing. In some studies, too much dietary iron has also been linked to cancer.
A study published in the European Journal of Cancer Prevention in November 2013 found an association between dietary and supplementary iron and colorectal cancer. Another study, published in 2008 in The Lancet Oncology showed that excessive iron plays a role in the development of breast cancer.
According to Dr Victor Hsue Chan-chee, president of the Hong Kong Association of Community Oncologists, iron is thought to be carcinogenic in that it accelerates the formation of the most dangerous type of free radical - hydroxyl radicals. In addition, excessive dietary iron suppresses your body's immune system, lowering your body's defences against the disease.
