A very amiable person. For work reasons, we became good friends soon after he came. This old comrade Gu is very interesting. After graduating from high school, he went to a shipyard as an apprentice instead of directly applying for the university. Later, because of environmental protection, fishery production in Switzerland became more and more depressed. At the age of 38, he went to the University of Zurich to study biology. I can't find a job after graduation, so I have to continue my studies. I didn't get my doctorate in fungi until I was in my forties.

. In fact, at that time, the boss didn't care about his study of fungi, just wanted to find someone to cut electric lenses. He is the best candidate.

Being single for many years has made me a chef myself. I remember it was a Saturday afternoon, and I made a sumptuous dinner, during which one dish was fried vegetarian meat with mushrooms. I bought mushrooms specially in China food supermarket. They are delicious, which can be described as delicious. I don't remember how many dishes I cooked, about 5-6. In a word, he ate with relish, but did not even move the fried meat with mushrooms.

After I introduced the history that I like eating mushrooms very much, Comrade Gu told me not to eat more of this mushroom. You can eat up to 200g per month.

. I asked why? He said that although mushrooms are good, they have a very important feature, that is, they are extremely rich in heavy metals, which can reach more than 100 times at most. Almost all heavy metals, such as lead, mercury and nickel, are enriched in mushrooms. However, our bodies have no mechanism to excrete heavy metals. Over time, these heavy metals will accumulate in the renal tubules, which is serious.

At that time, I was doing a small project about the kidney development of mice for my boss, and I read a lot of information about kidney development. I retorted that the kidney is very compensatory,

1/4 kidneys can maintain the needs of human metabolism. Gu immediately said to me: "Yes, yes, so I suggest you eat less, eat 200 grams a month, and let your kidney slowly compensate!" " " .

A few days later, Lao Gu found me specially and said that he had asked his colleague who studied the "physiology" of mushrooms. This old man (who is also a foreign devil) is even better: he said that he couldn't eat a piece, and joked that "the average life expectancy of Swiss people is over 80 years, which is due to not eating mushrooms."

. I'm still skeptical about this question, because living habits are formed from childhood. When I was a child, I couldn't eat anything good in the countryside. This kind of mushroom is everywhere in the grass, and I really ate a lot without spending money. Later, there was more oil and water, and everything in braised mushrooms was delicious. I am a person who likes eating mushrooms very much. Later, I read a report in NZZ (New Zurich News) that in Ukraine, Germany and other areas polluted by the Chernobyl nuclear accident, experts prescribed that mushrooms should be planted vigorously to enrich heavy metals and harmful metals in these radiation-polluted areas and restore them to the pre-pollution level as soon as possible. After reading this report, I began to really believe what my brother said.

Problem, and many popular science articles in China have not mentioned this problem, so I think I should tell the secret I know. I didn't say it before, mainly because I am neither an expert nor a reader on this issue.

I have read the relevant research materials, and I am afraid that I am wrong and will be criticized to pieces. However, after writing this article, use "pollution, mushrooms"

After searching in Baidu, there are still several articles saying that mushrooms suspected of nuclear pollution in the former Soviet Union and Ukraine should not be eaten.

I remember when I was a resident, cisplatin was already the basic drug when I was doing chemotherapy for ovarian cancer patients, and it is still the first choice for ovarian cancer chemotherapy. Cisplatin has played a great role in improving the prognosis of patients with ovarian cancer, making the survival rate before 1980s 1 year less than 20%.

After using this drug, its 2-year survival rate exceeds 80%

. Now this drug is also used for chemotherapy of other malignant tumors. However, this drug has a great side effect, that is, it damages the kidney like aminoglycoside antibiotics and causes tubular necrosis. When I was a young doctor, I was not very clear about the efficacy of this medicine. A patient has to do 12- 14 courses of treatment (usually once a month, a course of treatment, a patient has to do it for more than a year), but I don't see many patients who stop taking drugs because of impaired renal function. In recent 10 years, it was found that ovarian cancer patients only need 6 courses of chemotherapy, and the curative effect is similar to that of 12 courses of chemotherapy. Recently, however, it was found that three patients had different degrees of renal insufficiency in the fourth course of treatment. Of course, the first thing we think of is the damage of cisplatin to the kidney, but why are these patients' renal compensatory ability so poor? With this question, I asked these patients about their eating habits during the follow-up and found that they all really like mushrooms as much as I do. The environmental pollution in China is no secret. The land is not divided into north and south, the water is not divided into east and west, and the gas is not divided into inside and outside, and almost all of them have been polluted to varying degrees. For mushrooms growing in these polluted soil and water, you can

Of course, they can enrich heavy metals in soil, water and air. After we eat it, these heavy metals will deposit in our renal tubules, and over time, they will harm our kidneys. Once we

Many people in China feel that it is really meaningless for everyone to copy because they can't find a topic to do. I really hope that after reading this article, friends who study chemistry, food or medicine will check the heavy metal content of mushrooms in the market to see how many heavy metals these mushrooms have, whether we can eat them or not, and what is the best amount to eat? 10 years ago, Comrade Gu suggested that I eat no more than 200 grams of mushrooms every month. Now I think this amount should be reduced a little.

Mushrooms are my favorite food, but they have also become my fear. I hope our environment is not polluted! A comment:

I think this problem should be treated concretely. Mushrooms have a strong ability to enrich heavy metals, although this is the first time I have heard of it.

Yes, but I believe it should be true. Even so, I think relevant scholars should give the main channels for mushrooms to enrich heavy metals, such as air enrichment, soil enrichment, or vacuum attachment. Heavy metal lead

There are mushrooms on the kitchen mop. There has to be a contrast. Also, we should compare which mushroom has strong enrichment ability. Ask these two foreign scientists to give specific scientific forms. After all, this is the same as genetic modification.

The problem is different. If the enrichment rate of heavy metals in mushrooms can be greatly reduced by improving the planting environment, how can so many people be scared away? After all, in the face of genetic modification, we ordinary people do not have many choices.

I attach great importance to this problem. I hope you can follow this topic and pay a return visit to those two foreign scientists.
