Golden rice, a famous transgenic rice, looks golden in appearance and is rich in carotene and vitamin A. The difference between golden rice and other rice is that it can help the human body absorb vitamin A well. Researchers have learned that the genes of golden rice are artificially refined and added, which may achieve some desired effects, but it will also increase and accumulate trace toxins in food. These toxins can cause acute and chronic poisoning in humans, or have carcinogenic, teratogenic and mutagenic effects. So don't eat too much.
