Study finds that nutritionally enhanced rice reduces iron deficiency

Breeding rice with higher levels of iron can have an important impact on reducing micronutrient malnutrition, according to a new study in the Journal of Nutrition. The research, conducted by scientists from the Philippines and the United States, is a major step forward in the battle against iron deficiency, one of the developing world's most debilitating and intractable public health problems affecting nearly 2 billion people.

The lead authors of the article, Dr. Jere Haas from the Division of Nutritional Sciences at Cornell University, Dr. John Beard and Dr. Laura E. Murray-Kolb from the Department of Nutritional Sciences at Pennsylvania State University, Prof. Angelita del Mundo and Prof. Angelina Felix from the University of the Philippines Los Baños, and Dr. Glenn Gregorio from the International Rice Research Institute (IRRI), oversaw a study in which religious sisters in ten convents in the Philippines included the nutritionally enhanced rice in their diets. After 9 months, the women had significantly higher levels of total body iron in their blood.

"This study documents a major breakthrough in the battle to prevent micronutrient malnutrition," said Dr. Robert Zeigler, director general of IRRI. "These results are especially important for rice-eating regions of the world where more than 3 billion of the world's poor and undernourished live."

The iron-dense variety of rice used in the research (known technically as IR68144-3B-2-2-3) was developed and grown at IRRI and then tested by an international team of researchers from Cornell University, Pennsylvania State University, the University of the Philippines Los Baños and IRRI. The research initiative was originally spearheaded and funded by the Washington-based International Food Policy Research Institute (IFPRI), with support from the Asian Development Bank and the Micronutrient Initiative. HarvestPlus, an international, interdisciplinary research program focused on breeding crops for better nutrition and led by IFPRI and the International Center for Tropical Agriculture (CIAT), will continue to work with these research findings and partners to increase the level of nutrient density in rice to be even more effective.

"We view this study as a 'proof of concept,'" said Zeigler. "We now know that, if plants are bred with higher levels of iron and other micronutrients, they will improve the nutritional status of people who consume them. This has dramatic implications."

Through a process known as "biofortification," plant breeders are developing staple foods with higher levels of essential micronutrients. This study demonstrates that iron-biofortified rice can raise levels of stored iron in the body and can significantly contribute to reducing micronutrient malnutrition.

"In the past, we relied on supplements and fortification to overcome vitamin and mineral deficiencies," said Howarth Bouis, director of HarvestPlus. "Now we know that biofortification also works, giving us an additional tool in this crucial battle."

The United Nations and other donors spend millions of dollars a year on iron supplements and other strategies to ease the enormous damage wreaked by iron deficiency and related conditions. Iron deficiency can affect a child's physical and mental development, and each year causes more than 60,000 maternal deaths during pregnancy and childbirth. Recent statistics from the Micronutrients Initiative of Canada and the United Nations Children's Fund indicate that more than half of the developing world's children between 6 months and 2 years of age are iron-deficient during the critical period of their growth when brain development occurs. Many of the worst affected are found among Asia's poorest, but iron deficiency is also widespread in Africa, affecting more than 80 percent of young children in some countries.

Nutritional experts correctly advise that the best solution is a balanced diet of f ruit, vegetables and meat, but, for the very poor, such choices are simply not possible and so they depend predominantly on staple foods to stave off day-to-day hunger. This is especially true in isolated rural areas where under-resourced and overstretched public health systems struggle to improve the overall nutrition of the world's poor through nutritional supplements. In these areas, commercially fortified foods also have difficulty making it into the mouths of the hungry and so malnutrition persists.

"The fact that biofortified foods can have an impact on nutritional status in humans is an enormously exciting breakthrough," Zeigler noted. "It is time to shift the agricultural research agenda, and the rice research agenda in particular, away from quantity and toward better-quality food. This may be the start of a nutritional revolution--a very appropriate follow-on from the Green Revolution and one that is desperately needed by millions of the world's poor and undernourished."
