Purple potatoes are not genetically modified food, but just a crop that normally exists in nature, and its relationship with ordinary sweet potatoes is just like the relationship between the black and yellow races, both of which are the result of evolution in nature for a long time! There is no need to transfer the emotion of "fear of conversion" to the purple potato.

Why are purple potatoes purple?

According to the Grain and Oil Market News, purple potatoes are purple mainly because they are rich in anthocyanin pigment, which is water-soluble, so as long as the purple potatoes in the water will lose color. And this pigment will also be different with the acidity and alkalinity and change color, in a neutral environment in purple, alkaline environment is blue-green, acidic environment is purple red.

Purple sweet potato fiber content is high, this kind of material can increase the volume of feces, promote gastrointestinal peristalsis, clean up the intestinal lumen retained mucus, stagnant gas and corruption, discharge feces in the toxic substances and carcinogens, keep the stools unimpeded, improve the environment of the digestive tract, to prevent gastrointestinal diseases. Zinc, iron, copper, manganese, calcium, selenium in purple potatoes are natural, and iron, calcium content is particularly high. And selenium and iron is the human body anti-fatigue, anti-aging, blood necessary elements, has good health care function, selenium is "anti-cancer king", easy to be absorbed by the body, effectively stay in the blood serum, repair heart muscle, enhance immunity, remove the body to produce cancer free radicals.

What is the difference between purple potatoes and sweet potatoes!

Sweet potato, also known as sweet potato, sweet potato, yam, etc.. Sweet potato contains a variety of nutrients that the human body needs. Every 500 grams of sweet potato can produce about 635 kilocalories of calories, containing 11.5 grams of protein, sugar 14.5 grams, 1 gram of fat, phosphorus 100 milligrams, 90 milligrams of calcium, 2 grams of iron, 0.5 milligrams of carotene, and contains vitamin B1, B2, C and niacin, linoleic acid, and so on.

The content of vitamin B1 and B2 is 6 times higher than rice and 3 times. Especially sweet potato is rich in lysine, and rice, flour precisely lack of lysine. But many hair people have not realized.

According to Grain and Oil Market News, Fan Zhihong, an associate professor at the Department of Nutrition and Food Safety in the College of Food Science at China Agricultural University, pointed out that purple potatoes are not genetically modified products, in fact, natural plants are supposed to come in a variety of shapes. The same kind of thing, big and small, colorful. People only see products of one size and one color simply because humans commonly grow this variety.

Fan said that by crossing the various tomato varieties with each other, you can breed tomatoes in different colors, such as crimson, pink, yellow and green, as well as different sizes. These are very normal things, and genetically modified is not related at all. It is just as if there are different ethnic groups in the human race, and when different races intermarry, they will give birth to mixed-race children with changes in nose height, mouth shape, eye and hair color, height and height, and so on. On the contrary, some genetically modified products tend to look normal, so that color or size cannot be used to determine whether they are genetically modified or not.

So feel free to buy purple potatoes to eat.
