Rice research agencies and the Helen Kellen International (HKI) are working together to reduce blindness and death among children and other vulnerable sectors due to vitamin A deficiency.
The International Rice Research Institute (IRRI) and national rice research institutes in Bangladesh are conducting research to further develop and evaluate the golden rice variety.
The golden rice is a unique type of rice that contains beta carotene, a source of vitamin A.
Vitamin A deficiency is the leading cause of preventable blindness in children. It also impairs immune system function and increases the risk of death from certain childhood diseases.
The Bangladesh Rice Research Institute (BRRI) and the Philippine Rice Research Institute (PhilRice) have been working with IRRI on Golden Rice for several years. They are leading the development of Golden Rice varieties in their countries.
The Helen Keller International (HKI) is a leading global health organization that reduces blindness and prevents malnutrition worldwide.
Helen Adams Keller (June 27, 1880 - June 1, 1968) was an American author and political activist who became blind when she was 19 months old. According to Wikipedia, she contracted an illness described by doctors as "an acute congestion of the stomach and the brain", which might have been scarlet fever of meningitis.
Globally, approximately 670,000 children die every year and another 350,000 go blind because they are vitamin A–deficient. According to the World Health Organization stated in its website that Vitamin A deficiency (VAD) is the leading cause of preventable blindness in children and increases the risk of disease and death from severe infections. In pregnant women VAD causes night blindness and may increase the risk of maternal mortality.
“IRRI and its partners have been working on Golden Rice for about ten years to develop a safe and effective way to address vitamin A deficiency, prevent blindness, and save lives,” said Dr. Gerard Barry, Golden Rice Network coordinator and IRRI’s Golden Rice project leader. “Our latest stage of work is now supported by the Bill & Melinda Gates Foundation and will bring in HKI - a new partner from the nutrition sector - to further understand how well Golden Rice can reduce vitamin A deficiency.”
HKI has been advocating for the elimination of vitamin A deficiency for more than 40 years, working with governments and other partners to reach those most in need through various interventions.
“The most vulnerable children and women in hard-to-reach areas are often missed by existing interventions that can improve vitamin A status, including vitamin A supplementation, food fortification, dietary diversification, and promotion of optimal breast-feeding,” said Ms. Nancy Haselow, HKI vice president and regional director for Asia-Pacific, who has been designing, implementing, and testing vitamin A delivery programs for more than 20 years.
“We welcome the opportunity to see if Golden Rice is efficacious and can fill the gap in access to adequate vitamin A for all vulnerable groups in a sustainable way,” she added.
According to research published in the American Journal of Clinical Nutrition, daily consumption of a very modest amount of Golden Rice - about a cup (or around 150 g uncooked weight) - could supply 50 percent of the recommended daily allowance of vitamin A for an adult.
“Since a large proportion of vitamin A-deficient children and their mothers reside in rice-consuming populations, particularly in Asia, Golden Rice should substantially reduce the prevalence and severity of vitamin A deficiency, and prevent at least hundreds of thousands of unnecessary deaths and cases of blindness every year,” said Dr. Alfred Sommer, professor and dean emeritus, Johns Hopkins Bloomberg School of Public Health. Dr. Sommer is an internationally acclaimed public health scientist who has been at the forefront of research into vitamin A deficiency, leading major studies that were fundamental to the current understanding of the effect of vitamin A supplementation on mortality, malnutrition, and blindness.
“We are conducting our breeding carefully to make sure that the new golden rice variety retains the same high yield, pest resistance, and excellent grain and eating qualities while helping to address the pervasive problem of vitamin A deficiency in the Philippines,” said Dr. Antonio Alfonso, chief science specialist and Golden Rice team leader at PhilRice.
“I am delighted with our success in breeding a golden rice version of Bangladesh’s most popular rice variety, BRRI dhan29, which we hope will make a substantial contribution to reducing vitamin A deficiency across the country,” said Dr. Alamgir Hossain, principal plant breeder at BRRI.
Golden Rice, which is genetically modified, will be available to farmers and consumers only after it has been approved by national regulatory bodies. This project will also generate and collect safety information related to golden rice for submission to regulators as early as 2013 in the Philippines and 2015 in Bangladesh. Golden rice is expected to cost farmers about the same as other rice, and they will be able to save seeds for replanting.
The inventors of golden rice, Professor Ingo Potrykus and Dr. Peter Beyer, donated the technology in 2000 as a gift for resource-poor farmers in developing countries because of its enormous potential to benefit public health.
