Ensuring 'health for all' remains a persistent and entrenched global challenge. G20 governments are in a position to elevate the priority accorded to health, and acknowledge the centrality of health to attaining the SDGs. The authors call on G20 leaders to build nations that are more inclusive and less divided, by: adopting a Health-in-All-Policies approach, prioritizing the most vulnerable, engaging citizens in policy processes, and filling health data gaps.(Published as Global Solutions Paper) JEL I1 I18
Fortification of a commonly consumed food is often an effective and relatively inexpensive method to alleviate the problem of human vitamin A deficiency. However, among the problems associated with food fortification, stability of the nutrient in the food vehicle must be considered. We tested stability of vitamin A (retinyl palmitate) in commercially available fortified cooking oil from Bolivia under parameters of storage time, temperature and humidity, and light exposure, in both opaque and translucent original containers. Containers of fortified soybean oil were incubated for 36 weeks in chambers maintained at either 40C (75% relative humidity) or 25C (60% relative humidity), at light intensity 2400 lux. At intervals, samples were withdrawn and analyzed by HPLC. All samples showed similar concentrations of vitamin A (32 to 50 ug retinyl palmitate per mL oil) at the beginning of the trial. After 4 weeks (maximum commercial turnover time of the oil), vitamin A content of the samples in translucent containers had decreased to 21% (25C) or 9% (40C) of initial values; however, samples in opaque containers retained 62 to 68% of initial vitamin A. Samples in opaque containers retained 62% (at 25C) or 50% (at 40C) of vitamin A for 17 weeks of treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
