Evidences of Selenium Deficiency in Brazil: from Soil to Human Nutrition
It is anticipated that world demand for food will double in the period from 1990-2030,the increase being 3.5 times in developing countries (Daily et al.,1998).Malnutrition has increased,reaching almost half of the world population,particularly among pregnant women,infants,and children (Welch,2008). This is partly due to soil micronutrient deficiencies.Deficiencies of iron (Fe),iodine (I),selenium (Se) and zinc (Zn) are today the major concern in relation to human health,especially in developing countries. According to the World Health Organization more than 2 billion people could be anemic as a consequence of Fe deficiency (Allen et al.,2006).It has been suggested that one fifth of the population is not ingesting adequate amounts of Zn (Hotz and Brown.2004).Combs (2001) has even estimated that between 0.5 and 1.0 billion people could be deficient in Se worldwide.
