Pilgrims-seafood+vitamin C= poison?
The rumor started from 5438+ 10 in June last year, and several online forums pushed the message that "a pair of little sisters in Yancheng died after eating crabs and persimmons".
Many people think that not only crabs and persimmons, but also crabs and foods containing vitamin C are at risk of poisoning. Similarly, shrimp and vitamin C eat arsenic together.
The truth is that arsenic in crabs will not be poisoned unless it exceeds the standard by hundreds of times. Eating a few kilograms of contaminated crabs and 5 kilograms of tomatoes at a time can lead to poisoning. Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety, College of Food Science, China Agricultural University, said that it is widely rumored that shrimps and crabs cannot be eaten together with foods containing VC. In the final analysis, they are worried about arsenic pollution in aquatic products. It should be noted that crabs are easy to cause allergies and food intolerance. But this does not mean that everyone must fast vegetables and fruits containing VC when eating crabs.
2. Can fruit enzymes detoxify and nourish the skin?
Rumor According to the popular saying on the Internet, fruit enzyme is the product of sealed fermentation after adding sugar to fresh fruit; It is said that the word "enzyme" was introduced from Japan, became popular in Taiwan Province Province, and then "re-exported" to the mainland. The Chinese standard expression is called "enzyme". It is said that enzymes contain lipolytic enzymes, which can decompose human body fat and make people lose weight and keep fit. Moreover, enzymes can also purify blood, enhance physical fitness, diminish inflammation and prevent alopecia. ...
Truth enzyme is also protein, which loses its activity when eaten in the stomach. Homemade enzyme operation is not standardized, and there is a risk of illness!
According to Song Quanhou, vice president of China Food Fermentation Industry Research Institute and director of the National Food Quality Supervision and Inspection Center, according to the relevant national standards, as long as the fruit enzyme products are produced within the permitted range, there is not much safety risk. However, the self-made process is not as strict as industrial production, so it is impossible to carry out strict sterilization. It may be that raw materials or pathogenic bacteria in the air are mixed in the self-made fermentation process, which may lead to risks such as diarrhea.
3. Anti-smog-pig blood fungus clears the lungs and prevents smog?
It is rumored that pig blood can absorb the "garbage" in the body. After the plasma protein of pig blood is decomposed by human gastric acid and digestive enzymes, it will produce a substance that can detoxify and moisten intestines. This substance can react biochemically with dust and harmful metal particles that invade the human body, become waste that is not easily absorbed by the human body, and then be excreted from the digestive tract. Similarly, auricularia auricula also has the effect of clearing away lung heat.
The principle of "clearing lung" mainly refers to reducing the damage of dust in the air to the respiratory system. Foods such as auricularia auricula and pig blood enter the digestive tract and adsorb some harmful substances through dietary fiber in the intestine, but they can't stop the harm of smog particles to the lungs.
Yi Zhu, an associate professor at the College of Food Science and Nutritional Engineering of China Agricultural University, said that theoretically, these foods can't clear the lungs, but they should be understood as a broad concept, that is, they are beneficial to the health of breathing-related parts. The lung-clearing effects of pig blood, duck blood and auricularia auricula are limited to folk word of mouth, and are not seen in Chinese medical classics. Sydney, tremella, fungus, lily and honey are refreshing to eat.
Pig blood, chicken blood and duck blood can supplement iron on the premise of food safety. Their rich hemoglobin iron is directly absorbed by intestinal mucosal epithelial cells in the form of porphyrin iron, which has high absorption and utilization rate. Studies have shown that animal blood can reduce the absorption of some toxic substances in human intestine and accelerate the excretion of toxic substances in intestine.
In smog, PM2.5 can directly enter and deposit in the bronchioles of the lungs. Unfortunately, there is no scientific evidence that all components can reach the gathering place of PM2.5 after digestion and absorption into the blood, so as to remove PM2.5, and it is impossible to expect food and smog to meet hand in hand.
