Rice, also known as rice, is a common food crop. After being harvested and processed, it is the rice that we often eat, which is the "first of the five grains".
Wheat can be ground to make bread and other foods, and it can also be fermented to make beer.
Soybean, called glutinous rice in ancient times, is rich in protein, which is often used to make bean products.
Millet is actually corn, and it is also one of the whole grains, and it is called longevity food.
Potato food mainly refers to those tuber crops, such as sweet potato and potato.
Historical background
In fact, there were not only grains at the beginning. As early as the Western Zhou Dynasty more than 3,000 years ago, ancient China people picked wild rice for food and listed it as one of the "Six Grains". The ancients regarded wild rice as delicious and thought it was fragrant. After the Han Dynasty, people began to plant Zizania latifolia, and it was regarded as an important food from then on until the Tang Dynasty.
However, due to various reasons, people's domestication and cultivation of Zizania latifolia has never been as successful as rice and wheat, and the yield of Zizania latifolia has always been low. Moreover, there is also a smut fungus, which will seriously affect its output.
The underground roots of Zizania latifolia contaminated with smut will expand continuously, and no seeds can be produced. But unexpectedly, after the stem of the drug was infected and swollen, it tasted very delicious. In this way, the rhizome of Zizania latifolia, which is swollen by smut fungus, has become another food that southerners like to eat.
Because of their thick and interlaced roots, people call this plant "Zizania latifolia", and different regions call them Zizania latifolia, Zizania latifolia, Zizania latifolia and bamboo shoots. Because Zizania latifolia tastes fresh and sweet, people began to plant Zizania latifolia as a vegetable instead of as a staple food.
