Vitamin D is important for bone mineralization and calcium metabolism and recently a potential role for vitamin D in the prevention and treatment of infections has been highlighted. There are limited number of dietary sources for vitamin D such as fatty fish, fortified commodities and supplements. High prevalence of vitamin D deficiency in immigrants with background from Africa, Asia and the Middle East is reported in the Nordic countries. Common risk factors for vitamin D deficiency also reported in the Nordic countries such as low sun exposure, low intake of vitamin D containing food and supplements, duration of residence in the host country and prolonged exclusive breastfeeding without supplementation. Common measures to achieve adequate vitamin D intake and status among immigrant populations in the Nordic countries are highly needed.
