Is selenium-enriched rice really good?

Selenium-enriched rice contains a lot of selenium. As an essential trace element for human body, it has anti-cancer and tumor growth inhibition effects.

The recommended daily intake of selenium per capita in China is 0.06 mg. The selenium content in ordinary rice is about 0.0 1-0.03 mg/kg, but according to national standards, the selenium content in selenium-enriched rice should not be lower than 0.07 mg/kg. In the process of planting selenium-enriched rice, it is necessary to supplement selenium artificially and apply selenium fertilizer in farmland to ensure that the selenium content of rice reaches the standard.

Organic rice can't use pesticides and fertilizers in the planting process, which requires more manpower input, and its output is lower than that of ordinary rice, so its production cost is relatively high. However, wash-free rice can be eaten without washing. In order to achieve this goal, it is necessary to add the process of removing rice bran powder in the processing, which indirectly increases its production cost and leads to its higher price than ordinary rice.

However, the more expensive the rice, the better. For example, some selenium-enriched rice circulating in the market actually does not increase the selenium content through scientific planting in the normal rice growth process, but adds selenium in the processing process after the rice matures, so that the produced rice can not increase the human body's intake of selenium after eating, but it is difficult for consumers to distinguish this kind of rice.

Extended data:

Selenium is one of the trace elements that human body must supplement every day, which can improve human immunity and prevent many diseases. Selenium-enriched agricultural products have great market value. Selenium can promote the activity of glutathione peroxidase, play the role of anti-oxidation and anti-aging, scavenge free radicals, and achieve the effect of anti-senile plaque. Selenium cooperates with vitamin E, and its antioxidant effect is 300-500 times that of vitamin E alone.

Moreover, selenium can prevent tumors and inhibit the growth of cancer cells; Reduce the toxic and side effects of radiotherapy and chemotherapy and anticancer drugs, reduce the toxicity of anticancer drugs to kidney, bone marrow and stomach, and relieve the pain of patients. Improve the human body's ability to resist radiation, selenium as a free radical scavenger, reduce the inactivation rate of enzymes caused by radiation, and reduce radiation damage.

People's Network-Ordinary rice, selenium-enriched rice and organic rice are not necessarily better because they are more expensive.
