British scientists have newly developed a transgenic rice rich in beta-carotene. The researchers believe that this type of rice helps to improve vitamin A deficiency in children in developing countries and the resulting blindness. British media reported on the 29th that the genetically modified rice grown by the Syngenta Biotech Company in the United Kingdom contains 20 times more beta-carotene than its predecessor. According to World Health Organization data, about 500,000 children worldwide are blind each year due to lack of vitamin A. Since the human body can convert β-carotene to vitamin A, the long-term consumption of this new type of transgenic rice can prevent children from vitamin A deficiency and the resulting blindness. Syngenta has decided to provide the rice varieties to laboratories in Asia for free trials and promotion. The beta-carotene-rich transgenic rice was first cultivated successfully in Switzerland five years ago, commonly known as “Gold Riceâ€. However, the amount of beta-carotene that children consume through the daily intake of “golden rice†is not enough to produce sufficient amounts of vitamin A, and the newly-developed transgenic rice has been significantly improved and contains significantly more beta-carotene. However, some experts pointed out that the problem of vitamin A deficiency cannot be solved by relying solely on a genetically modified food. People lacking vitamin A are likely to lack other vitamins and minerals. Therefore, the nutritional structure of the patient must be thoroughly investigated.
