In Huangdi Neijing, five grains are called: japonica rice, adzuki bean, wheat, soybean and millet. In modern times, grains usually refer to rice, wheat, soybeans, corn and potatoes. At the same time, grains other than rice and flour are customarily called miscellaneous grains, so miscellaneous grains generally refer to food crops.
Nutrients in whole grains are very rich, among which cellulose and minerals are several times that of ordinary white rice, and vitamin A, vitamin B 1, vitamin B2, vitamin C, vitamin E and trace elements such as calcium, potassium, iron and zinc are more abundant. Whole grains are the main source of dietary fiber, and most of them contain more unsaturated fatty acids, which can provide most nutrients necessary for human body.

Legend of the origin of whole grains:
In ancient times, people lived by eating the meat of birds and animals and the wild fruits on the mountain. When we arrived at Yandi Shennong, the number of people gradually increased. Emperor Yan thought, birds and animals will always eat less and less, and the fruits of plants and trees can grow once a year, which can be endless. If we can plant the strongest plants, we can have a new harvest every year and not worry about food shortage.
So, he cut some wood from the mountain, cut it into a shovel for digging and hoeing, and let his glazed poodle pull it in front, holding Lei behind him to master the direction. After the soil was turned over, some grass seeds were collected from the field, and soon after they began to be planted, these seeds broke through the ground and grew very luxuriantly. In autumn, I received several times more harvest.
Emperor Yan was very happy. In the second year, he called five ministers, namely rice, millet, millet, wheat and rice, to lead the people to divide lots and plant large areas separately according to the high dryness, humidity and fertilizer of the land.
This incident touched the Jade Emperor. He sent a red-faced god bird with a nine-eared seedling to fly over the land cultivated by Emperor Yan and scatter the seeds in the ground. He also ordered the sun god and the rain god to help take care of it. As a result, five different kinds have grown in five lots.
In order to facilitate memory, Emperor Yan named these five crops as rice, millet, millet, wheat, and glutinous rice according to the names of five ministers. This is the origin of the five grains. This autumn, more than a foot long golden harvest grew out of the grain. This kind of golden harvest can be harvested three times a year, and people can not only satisfy their hunger, but also live forever. As a result, many people are getting lazy.
The Jade Emperor was very unhappy when he learned about it, and told Migu to recover the immortal ingredients in the grain as quickly as possible, and he could only plant them once a year. He also ordered the red bird to stay on earth and urged the people to farm every spring. As a result, the god bird became the cuckoo now.
