history
Wild species originated in tropical America, and were successfully planted by Indians, with strong resistance to pests and diseases and easy cultivation. When Columbus first met the Queen of Spain, he presented the sweet potato brought back from the New World to the Queen, and Spanish sailors spread it to the Philippines. China was introduced from Luzon (now the Philippines), a Spanish colony at that time, and Chen Yi (1), a native of Dongguan, first introduced to Guangdong from Annan. In May of the 21st year of Wanli (1593), Chen Zhenlong, a native of Changle, Fujian, was brought back to China from Luzon. After the trial planting, "just in April, the soil was dug, and the mother and son joined hands, the big one was like an arm and the small one was like a fist." Fujian Governor Jin vigorously promoted and wrote seven new overseas biographies. The book Agricultural Policy describes the planting method of sweet potato in detail. Li Shizhen's Compendium of Materia Medica records: "Southerners use it as a rice and cereal meal, which is delicious when steamed ..., while people in the sea live longer, so they eat sweet potatoes instead of whole grains. Chinese medicine believes that sweet potato can tonify deficiency and benefit qi, strengthen spleen and stomach, and strengthen kidney yin [2]. At present, it is widely planted all over the world. 1995 American biologists found that sweet potato contains a chemical called dehydroepiandrosterone (DHEA), which can be used to prevent cardiovascular diseases, diabetes, colon cancer and breast cancer.

Sweet potatoes are very raw and easy to grow. In China, Hongkong and the mountainous areas of the New Territories, sweet potatoes are often visited by wild boars. The wild boar is very unwise. After eating it, it is necessary to dig again, thinking that there are still many buried below.
The sweet potato is planted without pesticides, the edible roots are buried underground, and the sweet potato leaves are less pests and diseases. The land does not need to be very fertile, does not need fertilization, and is not afraid of pesticide and fertilizer pollution. It is a very healthy alkaline food, containing the most minerals, such as potassium, calcium and phosphorus. There are many kinds, such as white, yellow, orange, red, purple and so on. Red is sweet, yellow is fragrant, and purple dissolves easily. The redder the flesh color, the more vitamin A there is. Vitamin C is rich, even higher than tomatoes. Vitamin e is twice as much as brown rice. Vitamin b is also available.
Vitamins A, B and C are mostly in the middle of sweet potato. After fresh sweet potatoes are stored, vitamins B and C will decrease, while vitamin A will increase. Sweet potato meat mainly contains starch, but less fat, and contains glucoamylase, which can slowly convert starch into sugar, so baked sweet potato has a strong caramel flavor. Sweet potato contains a kind of mucus, which is a mixture of polysaccharide and white matter. It has special effects on improving constipation, hemorrhoids and preventing arteriosclerosis. It also contains a female hormone, which has a good effect on women's skin protection and anti-aging. Smooth up and down, good natural spirit and beautiful skin.
White matter is mainly on sweet potato skin. Sweet potatoes are best eaten with skin after steaming. When eaten hot, the digestibility will increase and the sweetness will be strong. Don't eat after cooling. Starch is soft and easy to digest when it is hot. When it's cold, starch molecules recombine and become hard B starch, which is difficult to digest, just like eating. Hot rice is delicious, and cold rice is hard and unpalatable. If you don't eat sweet potato skin, the absorption of white matter will be less, and Hong Kong people in China are not used to eating sweet potato skin, so sweet potato is not suitable as a staple food. The ideal is as a non-staple food.
Sweet potato tender leaves can be cold or stir-fried, and the nutrition is much higher than that of ordinary vegetables. Just try it. After washing the tender leaves of sweet potato, blanch them with hot water, add soy sauce and sesame oil, and the taste is good.
