Golden Rice is an effective source of vitamin A.
BACKGROUND Genetically engineered "Golden Rice" contains up to 35 microg beta-carotene per gram of rice. It is important to determine the vitamin A equivalency of Golden Rice beta-carotene to project the potential effect of this biofortified grain in rice-consuming populations that commonly exhibit low vitamin A status. OBJECTIVE The objective was to determine the vitamin A value of intrinsic...
متن کاملVitamin D Food Fortification is an Effective Approach for Improving Vitamin D Status; A Systematic Review
Background: Low vitamin D (vit D) serum levels have been linked to various diseases such as multiple sclerosis, cardiovascular diseases, and diabetes. Maintenance of optimal vit D level should be supported by foods and supplements. Limited food sources of vit D made researchers focus on food fortification in recent years.

متن کاملWhy is golden rice golden (yellow) instead of red?
The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of beta-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice, phytoene synthase (PSY) and the bacterial carotene desaturase (CRTI), is lycopene, which has a red color. The absence of lycopene in Golden Rice shows that the pathway proceeds beyond the tr...
متن کاملGolden Rice
Golden Rice was engineered from normal rice by Ingo Potrykus and Peter Beyer in the 1990s to help improve human health. Golden Rice has an engineered multi-gene biochemical pathway in its genome [5]. This pathway produces beta-carotene, a molecule that becomes vitamin A when metabolized by humans [6]. Ingo Potrykus worked at the Swiss Federal Institute of Technology in Zurich, Switzerland, and ...
متن کاملThe Golden Rice Project
In the year 2000, more than 792 million people in 98 developing countries did not get enough food to lead a normal, healthy and active life, as estimated by FAO. More than 10 million children die of malnutrition every year, unnecessarily, and 90 percent of the fatalities are concentrated in only 42 developing countries. A vast majority of these deaths is linked to micronutrient deficiencies. Th...
