Biofortification of mungbean (Vigna radiata) as a whole food to enhance human health.

Mungbean (Vigna radiata (L.) R. Wilczek var. radiata) is one of the most important pulse crops grown in South, East and Southeast Asia. It provides significant amounts of protein (240 g kg(-1)) and carbohydrate (630 g kg(-1)) and a range of micronutrients in diets. Mungbean protein and carbohydrate are easily digestible and create less flatulence than proteins derived from other legumes. In addition, mungbean is lower in phytic acid (72% of total phosphorus content) than pigeonpea (Cajanus cajan L. Millsp.), soybean (Glycine max L.) and cereals; phytic acid is commonly found in cereal and legume crops and has a negative impact on iron and zinc bioavailability in plant-based diets. Owing to its palatable taste and nutritional quality, mungbean has been used as an iron-rich whole food source for baby food. The wide genetic variability of mineral concentrations (e.g. 0.03-0.06 g Fe kg(-1), 0.02-0.04 g Zn kg(-1)) in mungbean indicates possibilities to improve its micronutrient content through biofortification. Therefore biofortification of existing mungbean varieties has great potential for enhancing the nutritional quality of diets in South and Southeast Asia, where protein and micronutrient malnutrition are among the highest in the world. This review paper discusses the importance of mungbean in agricultural production and traditional diets and the potential of enhancing the nutritional quality of mungbean through breeding and other means, including agronomic practices.

Food crisis in the Asia-Pacific region.

The Asia-Pacific region was on track to achieve the Millennium Development Goal of halving the prevalence of extreme poverty by 2015, but recent dramatic rises in the price of rice and other staples have pushed millions of people back into hunger and poverty. This indicates that the region's food supply system is more fragile and imbalanced than what was previously believed. Proximate causes of the rise in staple prices can be found in market forces such as export restrictions and rising energy prices but the ultimate causes are policies that have led to under-investment in agricultural research and emergency mitigation. Large numbers of people in the Asia-Pacific were already undernourished prior to the recent price rises, relying on monotonous diets dominated by a few staples. Pushed into reducing their dietary diversity even further, many more millions are now suffering from hunger and deteriorating health. The most fundamental food crisis in the Asia-Pacific is one of poor diets, and this affects the obese just as much as the undernourished. The solution lies in a food system that focuses on producing balanced diets, developing safe production practices, increasing food supplies by reducing losses, and investing in the research that make it all happen. Improving food systems is a fundamental community expectation and can be a matter of government survival, but if the urgency to improve food supplies overrides improving diets, the long-term impact on national health will be severe. Proactive policies, regional responses, and more integrated scientific approaches are needed.
