Research

The University of California and Rutgers University have conducted studies showing "...higher crop yields, reduced pesticide use and fewer pesticide-related health problems..." amongst Chinese farmers who used GM rice strains. This was published in the peer reviewed journal Science in 2005.[25]

Dr. José L. Domingo of the Laboratory of Toxicology and Environmental Health, School of Medicine, at Rovira i Virgili University in Spain said, "According to the information reported by the WHO, genetically modified products that are currently on the international market have all passed risk assessments conducted by national authorities." These assessments found no risk to human health. Dr. Domingo advocates continued research in the areas of GM rice and its effects on humans.[26]
Clinical trials / food safety and nutrition research

In 2009, research results of a clinical trial of Golden Rice with adult volunteers from the USA were published in the American Journal of Clinical Nutrition. It concluded that "beta carotene derived from Golden Rice is effectively converted to vitamin A in humans".[27] In a summary about the research the American Society for Nutrition suggests the implications of the research are that "Golden Rice could probably supply 50% of the Recommended Dietary Allowance (RDA) of vitamin A from a very modest amount — perhaps a cup — of rice, if consumed daily. This amount is well within the consumption habits of most young children and their mothers".[28]

In response to the research, a group of 20 scientists suggested in an open letter that there might be deficiencies in clinical trials: "There is now a large body of evidence that shows that GM crop/food production is highly prone to inadvertent and unpredictable pleiotropic effects, which can result in health damaging effects when GM food products are fed to animals. More specifically, our greatest concern is that this rice, which is engineered to overproduce beta carotene, has never been tested in animals, and there is an extensive medical literature showing that retinoids that can be derived from beta carotene are both toxic and cause birth defects." [29] However, it is well known that beta carotene is found and consumed in many nutritious foods eaten around the world, including fruits and vegetables. Beta carotene in food is a safe source of vitamin A.[30]

The Food Allergy Resource and Research Program of the University of Nebraska undertook research in 2006 that showed the proteins from the new genes in Golden Rice did not show any allergenic properties.[31]

In August 2012, Tufts University and others published new research on Golden Rice in the American Journal of Clinical Nutrition showing that the beta carotene produced by Golden Rice is as good as beta carotene in oil at providing vitamin A to children.[32] The study states that "recruitment processes and protocol were approved",[32] but questions have been raised about the use of Chinese children to test the effects of Golden Rice.[33]
