What genetically modified foods are there in China?
It is reported that there are two kinds of genetically modified foods in China. One is genetically modified crops approved for commercial production in China, including papaya, sweet pepper, tomato, rice and corn. Ordinary sweet peppers and tomatoes are no longer produced because they are outdated, and rice and corn are not commercialized. Another case is the genetically modified agricultural products used in China to import processing raw materials, including soybeans, corn and rape, among which the most common is genetically modified soybean oil. Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, College of Food Science, China Agricultural University, said that imported soybean oil is basically genetically modified products.
Third, neither tomato nor purple potato is genetically modified.
There are many kinds of vegetables and fruits on the market now, including small tomatoes and cucumbers, big green peppers and strawberries, and besides sweet potatoes, there are purple potatoes. Their unusual posture and color are quite suspected of being genetically modified. In this regard, Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, College of Food Science, China Agricultural University, pointed out that these products are not genetically modified. "In fact, the shapes of natural plants are varied. The same thing, big and small, colorful. People only see products of one size and one color, just because this variety is widely planted by human beings. For example, by crossing various tomato varieties with each other, tomatoes of different colors, such as crimson, pink, yellow and green, and tomatoes of different sizes can be produced. These are normal things and have nothing to do with genetic modification. Just like people of different nationalities, after intermarriage between different races, mixed-race children will be born with different nose, mouth shape, eyes, hair color and height. On the contrary, some genetically modified products often look normal, so it is impossible to judge whether they are genetically modified products by color or size. "
Are the purple potatoes bought in the market generally genetically modified?
Purple potato is not genetically modified at all.
Just like people, black, white and yellow, that's all.

Were there purple potatoes in ancient times? When did purple potato come into being? Is it genetically modified?
Hello. Sweet potato was introduced into China only in the Ming Dynasty. There is no record of purple potato in previous historical materials. Purple sweet potato appeared in China around 1980. It may be a new species created artificially. Due to the serious asymmetry of information, there are no negative reports that eating purple potatoes will harm health in China, and most of them are words that advocate health. Whether anyone has done animal experiments and come to a conclusion is unknown. If you have relatives and friends overseas, you may wish to consult. The ancients were cautious about food, not eating it carefully. At present, the abuse of pesticides and fertilizers and the proliferation of genetically modified crops make our food worse and worse. So, pay more attention to diet.
Is purple potato a genetically modified food a rumor or a truth?
Purple potato is not a genetically modified food.
Purple sweet potato (scientific name: Dioscorea zingiberensis. ) Also called black potato, the flesh is purple to deep purple. Besides the nutrients of common sweet potato, it is also rich in selenium and anthocyanins. Purple sweet potato is one of the main raw materials of anthocyanin.
Medicinal value
Selenium and iron in purple sweet potato are essential elements for anti-fatigue, anti-aging and blood-enriching. In particular, selenium, known as the "king of cancer", is easily absorbed by the human body, can retain serum, repair myocardium, enhance immunity, eliminate free radicals in the body, inhibit the synthesis of cancer DNA and the division and growth of cancer cells, and prevent the occurrence of cancer diseases such as gastric cancer and liver cancer.
Purple sweet potato is rich in cellulose, which can increase the volume of feces, promote gastrointestinal peristalsis, clean up mucus, gas accumulation and corruption in intestinal cavity, discharge toxic substances and carcinogens in feces, keep defecation unobstructed, improve digestive tract environment and prevent gastrointestinal diseases. Besides the nutrients of common sweet potato, it also contains polysaccharides and flavonoids, and is also rich in selenium and anthocyanins, which has certain functions of preventing hypertension, relieving liver dysfunction and resisting cancer.

I heard that purple potato is genetically modified. Can I still eat?
With our ancient constitution, it is impossible to be poisoned, let alone genetically modified. What can't be eaten? There's nothing now. It's absolutely safe. Please help yourself. Even the air is polluted. Don't worry too much. If we think everything in advance, I really can't think of anything else we can eat.
How to distinguish transgenic purple potato?
Identification knowledge of genetically modified food
1, soybean
Non-GMO soybean: oval, a little flat. The navel is light brown. Beans come in different sizes. Soymilk is milky white.
Genetically modified soybeans: round. The navel is yellow or brown. Beans are about the same size Soymilk is a little yellow, and tofu made from this bean is a little yellow.
Simple test method: genetically modified soybeans do not germinate! You can test it with water! Local soybeans will germinate after soaking in water for three days! Genetically modified soybeans will not germinate, but will only swell.
From this germination experiment, people can find that these genetically modified soybeans are one-time fruits, and their germs are not necessary for life, so they have no ability to continue their offspring. It means that a person can be pregnant normally, but every time it is stillborn, it means that the continuation of life ends here. Then, if human beings eat all kinds of genetically modified foods on a large scale for a long time, the genetically modified fragments harmful to human beings will inevitably have a subtle influence until the normal genes of human beings are changed, the resistance is reduced, strange diseases abound, or fertility is lost, which is reasonable.
List of genetically modified foods in China!

Identification of transgenic vegetables;
Genetically modified vegetables generally have the following characteristics:
1, unlike traditional vegetables with uneven shapes, they are generally uniform in size, long in shape, bright in color and fresh in texture, such as cucumber, eggplant, loofah and onion;
2, non-traditional authentic taste, whether before or after cooking, the smell or taste are obviously different from traditional vegetables, such as sweet pepper;
3. Non-local seasonal vegetables, one of the characteristics of all kinds of vegetables is strong seasonality and regionality. Some non-local seasonal vegetables are obtained by transposing cold-resistant or high-temperature-resistant genes, rather than relying on long-term storage and transportation in other places.
The confirmed genetically modified foods are as follows: 1, lettuce 2, sweet pepper 3, herself tomato 4, purple sweet potato 5, African crucian carp 6 and African catfish (pond fish).
Beware of several well-known "genetically modified soybean oil" brands!
Genetically modified soybean oil has been rampant in China market for many years, taking advantage of consumers' insensitivity in China, or consumers' ignorance of "the potential harm of genetic modification". And it has caused incalculable potential damage to the health of our people, and it has also become the main reason for the encirclement and suppression of soybeans in Northeast China, making them on the verge of difficulties.
The main brands on the market now are:
1, Arowana brand, soybean oil, salad oil, blended oil, etc. , the market share is about 40%, and the employer is the Chinese Guo Henian family of Singapore Wilmar International+American ADM Company;
2, Fulinmen brand, soybean oil, salad oil, blending oil, etc. , the market share is about 30%, and the employer is state-owned COFCO+Singapore Wilmar International+American ADM Company;

Is purple potato a genetically modified food?
Purple potato is not a genetically modified food.
But why did purple potatoes rarely appear in the market in the past? This is because farmers' purple potato production is generally low, and farmers don't like planting; Purple sweet potato has anthocyanin smell and poor taste, so people don't like it, so it is rare in the market. In recent years, people began to pay attention to food nutrition and found that purple potato has high nutritional value. Many new varieties of purple sweet potato with high yield and good quality have been cultivated by agricultural scientific research units in various places, and the number of purple sweet potatoes in the market has increased, and the price is higher than that of ordinary varieties.
Is purple potato a genetically modified food?
No, it is produced by specific geographical conditions and breeding techniques.
Purple sweet potato: It is a kind of sweet potato. If you don't cook it, it will itch if you don't treat it like taro. After cooking, except that the heart is purple, it is nothing special with ordinary sweet potatoes, and it tastes particularly fragrant and sweet.
Neither are genetically modified foods. There are many kinds of food in China, so don't think it is genetically modified. . The table therefore underestimates the land of China, where genetically modified foods are not so developed.
