Iron deficiency is the most common and widespread nutritional disorder in the world. As well as affecting a large number of children and women in developing countries, it is the only nutrient deficiency which is also significantly prevalent in Industralized Countries. The numbers are staggering: 2 billion people – over 30% of the world’s population – are anaemic, many due to iron deficiency, and in resource-poor areas, this is frequently exacerbated by infectious diseases. Malaria, HIV/AIDS, hookworm infestation, schistosomiasis, and other infections such as tuberculosis are particularly important factors contributing to the high prevalence of anaemia in some areas.
Historians usually date the start of the Protestant Reformation to the 1517 publication of Martin Luther’s “95 Theses.” Its ending can be placed anywhere from the 1555 Peace of Augsburg, which allowed for the coexistence of Catholicism and Lutheranism in Germany, to the 1648 Treaty of Westphalia, which ended the Thirty Years’ War. The key ideas of the Reformation—a call to purify the church and a belief that the Bible, not tradition, should be the sole source of spiritual authority—were not themselves novel. However, Luther and the other reformers became the first to skillfully use the power of the printing press to give their ideas a wide audience.
