No, it is just a kind of potato with higher nutritional value than sweet potato and anti-aging.
Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety at China Agricultural University's College of Food Science, pointed out, "In fact, natural plants are supposed to come in a variety of shapes. The same kind of thing has big and small heads and colorful colors. People only see products of one size and one color simply because humans commonly grow that variety.
For example, by crossing various tomato varieties with each other, you can breed tomatoes of different colors, such as crimson, pink, yellow, and green, as well as different sizes. These are normal things, and not at all related to genetic modification. It's as if there are different ethnic groups of people, and when different races intermarry, they give birth to mixed-race children with changed nose heights, mouth shapes, eye and hair colors, and heights.
On the contrary, some genetically modified products tend to look normal, so that is why it is not possible to judge whether a product is genetically modified or not by its color or size."
An authoritative answer from Professor He, a researcher at the Institute of Nutrition and Food Safety at the Chinese Center for Disease Control and Prevention: "According to information released by the Ministry of Agriculture's Office of Agricultural Genetically Modified Organisms Safety Management on April 27, 2013,
China*** **issued agricultural GMO safety certificates for seven types of genetically modified plants: storage-tolerant tomato, insect-resistant cotton flower, altered-flower-color petunia, disease-resistant chili pepper, disease-resistant papaya, insect-resistant rice, and transphytase corn." Purple potatoes are not included in this, which gives us the very authoritative answer that purple potatoes are not genetically modified foods, they are natural foods.
I, the origin of purple potatoes
Purple potatoes are actually a type of sweet potato. The color of the skin of the tuber of this crop is yellow, orange, red, brown, purple and beige, and the color of the heart after cutting is white, red, pink, purple, yellow, orange and so on. We usually eat sweet potatoes, white potatoes are a kind of sweet potato. At present, there are about 6,500 varieties of sweet potatoes (including wild varieties and artificially cultivated varieties).
In 1984 by the Chinese Ministry of Agriculture and the Chinese Academy of Agricultural Sciences under the auspices of dozens of well-known sweet potato experts collectively prepared by the Chinese sweet potato Cultivation of page 34, clearly states: "sweet potato flesh color can be divided into purple, orange-red, apricot yellow, yellow, white, etc.", indicating that purple is one of the inherent flesh color of sweet potato, such as the Guangdong Farmer's varieties: bean paste potato, water spinach potato, snow potato, purple heart potato, purple flesh potato, Hainan purple potato, etc. are natural pure purple potato.
Two, purple potatoes super nutritional value
It has ordinary sweet potatoes in addition to the nutrients, but also rich in selenium and anthocyanins. It is because of the purple potato contains anthocyanin this characteristic, purple potato will appear purple, and the nutritional value is much more than the sweet potato.
Purple potatoes are rich in nutrients with special health functions, it contains about 20% protein, including 18 kinds of amino acids, easy to be digested and absorbed by the human body, including vitamin C, B, A and other 8 kinds of vitamins and phosphorus, iron and other more than 10 kinds of minerals, containing a large number of medicinal value of anthocyanins.
1, antioxidant
Everyone should know, anthocyanin is the most significant feature is antioxidant, can remove free radicals. And purple potato anthocyanins antioxidant capacity is surprisingly stronger than chlorogenic acid (an important health component in fruits such as apples) and vitamin C.
2, protect vision
This effect is not thinking of blueberries? In fact, purple potato anthocyanins on the growth of retinal pigment epithelial cells have a role in promoting the growth of retinal pigment epithelial cells, also has a potential role in the protection of eyesight. The difference between the anthocyanins in purple potatoes and blueberries for vision protection is not great, but purple potatoes are more cost-effective.
3, regulating the intestinal
Purple potato anthocyanins can change the microbial composition of the colon, significantly increase the intestinal bifidobacteria, lactobacilli and enterococci and other "good bacteria". Researchers believe that consumption of anthocyanin-rich purple potatoes is beneficial to the intestinal microbial environment and human health.
4, protect the liver
Purple potato anthocyanins for carbon tetrachloride-induced liver damage has a strong inhibitory effect.
5, the prevention of cardiovascular disease
Purple potato anthocyanins can well inhibit platelet aggregation and low-density lipoprotein oxidation, and platelet aggregation and low-density lipoprotein oxidation is the main cause of atherosclerosis.
