Until the Tang Dynasty, wild rice was still a popular food. The plants of Zizania latifolia look like Zizania latifolia, but the directional cultivation direction is different. Zizania latifolia is very tall and has wide leaves. The plants of Zizania latifolia are small and thin. Because wild rice is not easy to harvest and the yield is low. However, Zizania latifolia is becoming more and more popular, and its output is also very high. Therefore, there were a lot of artificial cultivation before the Southern Song Dynasty, and wild rice was basically extinct after the Southern Song Dynasty. There are only wild Zizania latifolia in China, and there are no cultivated varieties.
According to the analysis, the protein content of wild rice far exceeds that of rice and millet, the protein content of rice is about 7% ~ 8%, that of millet is about 9% ~ 14%, and that of wild rice exceeds 15%. When Americans discovered the high content of protein in wild rice, they bought wild rice from Indians. Because the source of wild rice is limited, they have to mix it with rice and supply it in supermarkets in small packages. After mixing, the protein content of rice can be increased to 65,438 04%.
Health care value:
After the Tang Dynasty, Zizania latifolia was gradually used as Chinese medicine. In Ming Dynasty, Li Shizhen's Compendium of Materia Medica and other works recorded that Zizania latifolia was used to treat diabetes and gastrointestinal diseases. Food science research has proved that the contents of arsenic, cadmium and lead in wild rice are very low, and animal experiments and population surveys have also proved that it is safe to eat. Zizania latifolia contains high nutritional value, especially rich in protein, minerals and vitamins. Its protein-efficacy ratio is 2.75, which is the source of high-quality protein and undoubtedly provides a good food resource for patients with diabetes, obesity and hyperlipidemia.
Previous studies have shown that whole grains are rich in bioactive substances, especially antioxidants, which can protect the body from oxidative stress and play an important role in improving chronic metabolic diseases, such as obesity, metabolic syndrome, diabetes, cardiovascular diseases and cancer. As a whole grain, Zizania latifolia is rich in flavonoids, anthocyanins, saponins, phytosterols and other antioxidant substances, which can effectively scavenge free radicals in the body and maintain the balance and stability of antioxidant and antioxidant system in the body.
