Abstract

The selenium (Se) status in South Australian adults from 1977 to 2002 is studied. It is concluded that men had a marginally higher plasma Se concentration than women.

Abstract

Iron deficiency is the most prevalent nutritional deficiency, affecting more than 30% of the total world's population. It is a major public health problem in many countries around the world. Over the years various methods have been used with an effort to try and control iron-deficiency anemia. However, there has only been a marginal reduction in the global prevalence of anemia. Why is this so? Iron and zinc are essential trace elements for humans. These metals influence the transport and absorption of one another across the enterocytes and hepatocytes, due to similar ionic properties. This paper describes the structure and roles of major iron and zinc transport proteins, clarifies iron-zinc interactions at these sites, and provides a model for the mechanism of these interactions both at the local and systemic level. This review provides evidence that much of the massive extent of iron deficiency anemia in the world may be due to an underlying deficiency of zinc. It explains the reasons for predominance of cellular zinc status in determination of iron/zinc interactions and for the first time thoroughly explains mechanisms by which zinc brings about these changes.

97. Nutritional Consequences of Using Organic Agricultural Methods in Developing Countries

Author

Abstract

In addition to improved yields, the use of organic methods can benefit the nutritional value of foods in several ways, compared with subsistence agriculture, and in some respects also when compared with the use of high-input conventional farming methods. The recycling of organic matter retards depletion of the soil and ensures that increases in yield are not offset by mineral deficiencies caused by unbalanced plant nutrition. City populations can use organic products to minimize their intake of pesticide residues and nitrate. Improved nutritional status of crops under low-input conditions can increase the contents of protein and vitamin A, but can also increase the contents of some anti-nutrients. Improved availability of firewood through agroforestry enables thorough cooking to ensure removal of anti-nutrients and full utilization of nutrients. Increased diversity of crops not only provides a more dependable food supply, but also increases the chance for obtaining a full complement of nutrients due to the variability in composition of different staple crops. The increased use of pulses, vegetables and fruit also overcomes short-comings in the nutritional values of the main staple crops, such as maize and rice. However, to obtain the full benefits from these methods, substantially increased and much more targeted research on the development and use of organic agriculture methods under tropical conditions is necessary, especially in connection with subsistence agriculture.
