Journal of the World Public Health Nutrition Association. www.wphna.org Volume 2, Number 7, August 2011 Introduction The Waorani people from Ecuador. Clothes are not necessary for brown- skinned people living in a tropical climate. This however is not our situation Most people in northern industrial countries, such as the UK where I come from, have an inadequate level of vitamin D in their bodies, especially in winter. These low levels are now known to be associated with a wide spectrum of serious diseases, many of which lead on to disability and premature death. The diseases associated with D deficiency include more than a dozen types of cancer, multiple sclerosis, diabetes type 1, heart disease, high blood pressure, and schizophrenia, as well as the classic bone diseases – rickets, osteoporosis and osteomalacia.
