Golden Rice Has Same Nutrients as Traditional Rice Except for the Increased Provitamin A Content

Compositional analysis of genically engineered crops determines significant
changes in nutrient composition as compared to its conventional counterpart.
A article published in the Journal of Agricultural and Food Chemistry
presents the results of the compositional analysis of paddy rice, straw, and
bran of biofortified rice (Golden Rice or GR2E) compared with samples of
non-transgenic, near-isogenic, control rice (PSBRc82) planted over two
growing seasons in the Philippines during 2015-2016 at four locations
representing the different rice-growing conditions in the country.

The grain samples were analyzed for key nutritional components such as
fiber, sugars, fatty acids, amino acids, vitamins, minerals, proximates, and
anti-nutrients. The results showed that the only biologically significant
difference between Golden Rice and the conventional rice was the amount of
beta carotene (vitamin A precursor) and other provitamin A carotenoids in
the grain. The rest of the compositional parameters were found to be within
the range of natural variability of conventional rice varieties with a
history of safe consumption. The average concentration of provitamin A
concentrations in milled Golden Rice can contribute up to 89-113% and 57-99%
of the vitamin A requirement for pre-school children in Bangladesh and the
Philippines, respectively.
