Advances in breeding for enhanced iron and zinc concentration in common bean in Eastern Africa.

Micronutrient malnutrition is one of the most serious health challenges facing vast sectors of Africa's population particularly resource-poor women and children. Main deficiencies include iron, zinc and vitamin A. Plant breeding has frequently been advocated as the most sustainable strategy of providing varieties of different food crop species with enhanced micronutrient density to combat the global hidden hunger problem which affects more than 2 billion people.

Inherently low concentrations of zinc (Zn), iron (Fe), iodine (I), and selenium (Se) in wheat ( L.) grains represent a major cause of micronutrient malnutrition (hidden hunger) in human populations. Genetic biofortification represents a highly useful solution to this problem.

Article Synopsis
- A multicenter study evaluated the impact of a restrictive fluid strategy versus a standard fluid strategy in ICU patients with septic shock, aiming to minimize fluid intake to avoid complications from positive fluid balance.
- By analyzing 48 patients over 5 days, the restrictive group received significantly less fluid (89.7 ml/kg vs. 114.3 ml/kg), resulting in a smaller cumulative fluid balance.
- However, after 28 days, both groups showed similar mortality and survival without life support, indicating no clear benefits of the restrictive strategy despite differences in fluid management during the initial week.
Effects of Culture Medium Enrichment with Zinc on Astaxanthin Accumulation in a New Strain of the Microalga .

High Zn concentrations in microalgal cells that produce astaxanthin as a feed additive can reduce the symptoms of malnutrition in aquatic animals. Therefore, in this study, we analysed the effect of Zn in the culture medium on the growth of a newly isolated microalgal strain ZY24. Zn and white light stress altered the pigment content in microalgal cells.

The WHO describes micronutrient deficiencies, or hidden hunger, as a form of malnutrition that occurs due to low intake and/or absorption of minerals and vitamins, putting human development and health at risk. In many cases, emphasis, effort and even policy revolve around the prevention of deficiency of one particular micronutrient in isolation. This is understandable as that micronutrient may be among a group of nutrients of public health concern.
