It depends on the brand. Different brands of selenium-enriched rice have different selenium content and quality. Generally, high-grade natural selenium-enriched rice has more than 20 yuan a catty. The better selenium-enriched rice, the selenium-enriched rice produced by Sanwangong, originated from Jiaoling, the "world longevity town". The local water source is rich in "manganese, strontium, zinc, selenium, germanium and other elements that can maintain human minerals". The soil naturally contains selenium and has little pollution and no heavy metals. Recommendation: Three bowls of public selenium-enriched rice have beautiful appearance, good taste, rich fragrance and rich nutrition.
