A video released by the media said that the Ministry of Health issued the Notice on 10 kinds of inedible foods, pointing out that preserved eggs, stinky tofu, monosodium glutamate, instant noodles, sunflower seeds, spinach, pork liver, beef and mutton, pickles, fried dough sticks and other 10 kinds of foods are harmful to human health.
Rumors:
First of all, the Ministry of Health has not issued the Notice on 10 kinds of inedible food. Next, we will carefully analyze these foods:
1, preserved egg
Video content: Preserved eggs contain lead, which is easy to lead poisoning.
Description: The lead content of traditional preserved eggs is really high. In order to reduce lead in preserved eggs, experts developed a "lead-free process" to produce preserved eggs.
The new national standard requires that the lead content in preserved eggs should be controlled below 0.5 mg/kg from 20 15 12 1, which is much stricter than the old requirement. So buying from the supermarket is basically no problem. However, the bulk preserved eggs in the farmer's market may have excessive lead.
2. Stinky tofu
Video content: Stinky tofu contains hydrogen sulfide, which damages organs (it is also said that Wang Zhihe has been ordered to stop production).
Explanation: There is hydrogen sulfide in stinky tofu, which is produced by the degradation of sulfur-containing amino acids, and it will also be found in salted duck eggs and preserved eggs. The problem is that our intestines also produce a lot of hydrogen sulfide. Stinky tofu really can't be eaten more, mainly because the sodium content is too high.
3, monosodium glutamate
Video content: monosodium glutamate will become pyroglutamic acid after heating, which will cause cancer. Eating 10g is harmful. The United States and Japan have legislated that it is illegal for anyone to eat MSG, but you can eat chicken essence, which is better than MSG.
Description: monosodium glutamate does turn into pyroglutamic acid after heating, but pyroglutamic acid is tasteless and will not cause cancer. We also suggest that if monosodium glutamate is used, it should be put in before cooking. Eating10g monosodium glutamate is definitely harmful, and a lot of10g will make your mouth thirsty. This year, experts' suggestions issued by the European Food Safety Agency put forward to limit the intake of monosodium glutamate, and the average adult should not exceed1.8g per day (taking the weight of 60kg as an example).
What are harelip, congenital heart disease and cerebral hypoplasia? These are all nonsense. In addition, chicken essence is a kind of compound seasoning. Its main component is actually sodium glutamate (monosodium glutamate), but some spices such as salt, nucleotide and sugar are added, which makes it more flavor than monosodium glutamate.
4. Instant noodles
Video content: preservatives.
Explanation: Instant noodles are not really healthy food, but preservatives and antioxidants in instant noodles are also conventional food additives, and their safety has been scientifically evaluated. As long as it is used legally, it will not affect human health. Pay more attention to its calorie and sodium content when eating instant noodles.
5. Sunflower seeds
Video content: Sunflower seeds are unsaturated fatty acids, which affect liver function and are easy to get fat.
Explanation: sunflower seeds are indeed high in fat and easy to get fat, but how can unsaturated fatty acids affect liver function?
Most vegetable oils are mainly unsaturated fatty acids (except coconut oil and palm oil), and there are also unsaturated fats in animal oils. How can it hurt the liver? Can't you eat all the oil?
6.spinach
Video content: Don't eat spinach over 40 years old. There is oxalic acid in it. When it combines with zinc in the body to form zinc oxalate, the body has no resistance. It combines with calcium to form calcium oxalate, which is easy to cause fracture due to calcium deficiency.
Description: Spinach does contain oxalic acid, but there are too many vegetables containing oxalic acid, such as amaranth, fresh bamboo shoots, bitter gourd and water bamboo. There are so many metal elements in the rice, how can the oxalic acid of spinach specifically take away your zinc? Spinach oxalic acid does not affect bone calcium deposition and has no causal relationship with stones. Spinach tofu is even a perfect match. Because oxalic acid is soluble in water, blanch spinach first and then cook it with tofu.
7. Pig liver
Video content: One kilogram of pig liver contains 400 grams of cholesterol, which is the most cholesterol. Do not eat or eat less pig liver.
Explanation: Don't eat more dirty pigs. There's nothing wrong with that. The cholesterol content of pig liver is really high. About 288 mg/ 100 g pig liver is rich in protein, vitamin A, vitamin B 1, vitamin B2, vitamin B6, folic acid and iron. Eating less is good for your health. In order to avoid the hidden danger of pig liver, do not choose pig liver from unknown sources, but choose pig liver produced by reputable enterprises.
8. Beef and mutton
Video content: There is a notice in Inner Mongolia that roast beef and mutton is not allowed. Contains carcinogenic "benzene" and "pyrene".
Description: Barbecue, especially the meat roasted or scorched with charcoal fire, does contain carcinogens-benzopyrene (sound skin, not finish), but it is not benzene and pyrene.
9. Pickles and pickles
Video content: Pickled vegetables, pickles and sauerkraut can be eaten in small quantities, and long-term consumption of ammonium nitrite in large quantities is easy to cause cancer.
Explanation: the content of nitrite in pickled vegetables is really high within a few days to ten days, but if it is pickled for a longer time, 20-40 days, nitrite will basically disappear and will not cause cancer. Don't eat more pickles because the sodium content is high.
10, fried dough sticks
Video content: There is alum in the fritters, which mainly contains aluminum. Aluminum can damage two organs-kidney and brain cells.
Explanation: Fried dough sticks are not healthy food, with high fat and sodium content, and the production of fried dough sticks cannot be separated from alum as a leavening agent. Alum contains aluminum and is mainly deposited in bones. The state has restrictions on the amount of aluminum used in fritters, and vendors often exceed the standard. It's best to go to a chain breakfast shop.
