Not to eat sprouted purple potatoes. Sprouted purple potatoes have toxins, resulting in purple potato rot damage to human health. Sprouting purple potatoes, starch and sugar will be degraded into the nutrients needed for germination, the degradation process of purple potatoes will release some toxins, resulting in purple potatoes easy to mold rot (due to starch decomposition effect of water increased, easy to bad) sprouted purple potatoes become soft and poor taste.

Sweet potatoes, also known as sweet potatoes, sweet potatoes, sweet potatoes, sweet potatoes, etc., is a favorite of our residents of food food and vegetables food. Sweet potatoes are very nutritious, rich in starch, dietary fiber, carotene, vitamins A, B, C, E, and potassium, iron, copper, selenium, calcium and other more than ten kinds of trace elements.
It is recorded that sweet potato has a variety of health effects. The Compendium of Materia Medica describes that sweet potato has the effect of "replenishing deficiency, benefiting vitality, strengthening the spleen and stomach, and strengthening kidney yin". Modern scientific research also confirms that sweet potatoes can help reduce weight, laxative, inhibit cholesterol, etc., thus helping to health and delay aging.
The purple sweet potato is a new variety of sweet potato with purple-black skin and purple-red flesh, which was introduced from abroad in the 1980s. At present, China's purple potato varieties are introduced from abroad, there are also domestic hybrid cultivation. On the market, the price of purple potatoes is higher than ordinary sweet potatoes, we will analyze whether it is value for money?
Purple potato basically contains sweet potato all the nutrients, rich in protein, dietary fiber, vitamins and trace elements. After Japan bred purple potato, compared the difference between purple potato and common sweet potato, found that lysine, copper, manganese, potassium, zinc in purple potato is 3-5 times of common sweet potato, especially iodine and selenium content, is 20 times of common varieties.
According to the analysis of the U.S. Agricultural Products Center, the nutritional value of purple potatoes produced in the U.S. is also much higher than that of other potatoes, in which lysine, potassium, manganese, zinc is 5-8 times higher than that of the ordinary sweet potatoes, while the content of iodine and selenium is more than 20 times higher than that of other sweet potatoes.
For the rice and noodles as the main food for our country residents, purple potatoes in the rich lysine can supplement the rice and noodles in the lack of lysine, therefore, purple potatoes and rice and noodles with food can achieve the role of complementary protein.
The reason why purple potatoes have a purplish red color is because they are rich in anthocyanins, which are not comparable to ordinary sweet potatoes. Anthocyanin is also a powerful antioxidant, and its ability to scavenge free radicals is stronger than vitamin C and vitamin E.
It can not only scavenge excessive free radicals through the indirect effect of increasing the activity of animal antioxidant enzymes, but its phenolic hydrocarbon group can also release electrons to replenish the free radicals through redox, thus scavenging free radicals directly.
The benefits of anthocyanins go beyond that, as more and more studies have shown that anthocyanins in purple potatoes can help constrain the development of certain cancers and serious vascular diseases and reduce their incidence. In addition, anthocyanins have the ability to enhance memory, prevent aging, prevent diabetes and obesity, and improve the optic nerve.
Another thing that makes purple potatoes particularly superior to regular sweet potatoes is that they are rich in selenium. Selenium is a component of the enzyme glutathione peroxidase, which has a special contribution to the removal of free radicals in the body; selenium is also an important contributor to the prevention of and fight against cancer.
From the nutritional composition, purple potatoes are indeed richer than ordinary sweet potatoes, but compared to the market price of far higher than ordinary sweet potatoes, its cost-effective is still debatable, after all, our body needs nutrients is not just eat a certain kind of food to supplement.
And purple potatoes and ordinary sweet potatoes, containing oxidative enzymes easily in the human gastrointestinal tract to produce a lot of carbon dioxide gas, so that people bloating, uh, gas, a large number of times to eat will also stimulate a large amount of secretion of gastric acid and thus produce a sense of "heartburn". Therefore, even if the purple potato has nutrition can not eat too much!
