WHO announced that Asba was "carcinogenic"!Can these common foods still be eaten?

◎ Technology Daily reporter Cui Shuang Fu Lili

According to the official website of the World Health Organization, on July 14, the International Cancer Research Agency, the World Health Organization (WHO) and the Food and Agricultural Organization (Food and Agriculture Organization) Food Additives joint Expert CommitteeEvaluation report of sweet impact on health.

The International Cancer Research Agency quoted the "limited evidence" of human carcinogenicity and attributed Asba to the list of human cancer. The joint expert committee reiterated that its daily intake was 40 mg per kilogram of weight.

This is the first time the International Cancer Research Agency has evaluated Asba Tian, and it is also the third evaluation of the joint expert committee.

After reviewing the existing scientific documents, both aspects have pointed out that there are limitations of existing evidence in cancer (and other health influences).

According to limited evidence of human cancer (especially liver cancer (especially liver cell carcinoma), international cancer research institutions classify Asba sweetly as possible to human cancer (group 2B).

The joint expert committee concluded that the evaluated data shows that there is no enough reason to change the daily permitted intake of Asba Tian’s weight 0 to 40 mg per kilogram of weight 0 to 40 mg.

Therefore, the committee reiterates that people can rest assured to eat within this daily limited edition.For example, assuming that there are no other aspects of food intake, a can contains 200 or 300 mg of Astaba sweet weight loss soft drinks. A 70 kg of adults drink more than 9 to 14 cans per day before the daily allowable intakeEssence

What is Asba sweet?

Recently, the rumors of Asba’s sweet carcinogenic are flying.

Asba is a sweetener widely used in food and drinks.Sugar -free cola and gum are indispensable.

For a long time, people are immersed in such sweet imaginations of "only enjoy sweetness and risk of weightlessness", and regard them as alternatives of sugar and good friends who "do not eat fat."But it was "carcinogenic" overnight, causing widespread discussion.

According to Fan Zhihong, a professor at the School of Food Science and Nutritional Engineering, China Agricultural University, Asba is a binary peptide made of two amino acids (L-phenylalanine and L-Skywinate), which contains a methyl esterEssenceIts sweetness is about 200 times that of sucrose, so the actual amount used to increase sweetness is much less than sucrose (white sugar, rock sugar, cotton sugar, brown sugar are mainly sucrose).

Asba sweet is only one of the synthetic sweeteners.Other commonly used synthetic sweeteners also include trichlorotonose, sweetin, and Anciemi.People are the most familiar with sugar alcohol sweetener, including dozens of sugar alcohols, such as liery alcohol, maltosol, glycol alcohol, etc. They are naturally existing sweet substances.Production.

Can’t "may cause cancer"?

In fact, it is not necessarily the same as that of a list of cancer objects.

Fan Zhihong introduced that international cancer research institutions combed related research on various materials, and made the rating of carcinogenic possibilities in accordance with the connection with the risk of cancer.

Among them, 1 category is "determined human carcinogen"; category 2 includes Class 2A (it is likely to cause cancer to humans) and 2B categories (may be carcinogenic); if it is included in Category 3Carcinogenic effects.According to the World Health Organization, Asba is included in the 2B group.

These categories are to warn people that controlling control in professional protection and daily life, and even avoid contact with those substances that may increase the risk of cancer.

Fan Zhihong admits that in fact, many types of foods contain 1 type of carcinogens listed by international cancer research institutions, or the food itself is included in the 1 or 2A and 2B carcinogens, but countries will not be prohibited from selling.The public still eats it.

She gives an example:

For example, alcohol in alcoholic beverages is included in the first type of carcinogen, but alcoholic chocolates, lum cakes, alcohol -brewed sweets, bad fish, and bad eggs are still loved.

For example, nitrosamine is also a certain carcinogen, but nitrite is widely used in processing meat products. The meat intestines, ham, and bacon bacon must be added with sodium nitrite, which will produce nitrine.Hai rice, scallops, shrimp skins, dried fish and the like, will naturally bring some nitamines.

For another example, polygon aromatic hydrocarbons such as barbecue food and fried foods are also determined carcinogens.But people’s enthusiasm for baking skewers has not diminished.

Disputes of sweeteners have never calmed down

Disputes about sweeteners have never stopped.The "sugar darling darlings" that once promoted the health and safety of the red moss glycol broke the news a few months ago. The results of the research published by the "Nature · Medicine" magazine found that a large amount of moss ingestion can promote platelet aggregation and thrombosis formation., Increase the risk of cardiovascular disease.The amount of 30 grams per day will produce adverse effects, and this amount is basically equal to the amount of sweetness required for a bottle of sweet drinks.

Not long ago, the World Health Organization also issued a report on sweeteners, reminding everyone to drink sugar -free sweet beverages and use various sweeteners, which is not good for preventing various chronic diseases.

However, Fan Zhihong also said that because the evidence of research is not strong enough and the results are not completely consistent. The World Health Organization and Food Additive Management Institutions of various countries have not yet banned them.

In the report released by the World Health Organization, Dr. Mary Schubauer-Berigan, who was planned by the International Cancer Research Agency, said, "The evidence of human and animals has limited evidence and the mechanism of how carcinogenicity occurs.Carry out more research to improve our understanding of whether the consumption of Asba’s sweetness constitutes carcinogenic hazards. "

"The joint expert committee also considers the evidence of cancer risk in animal and human research, and concluded that the evidence of eating Asba sweet and human cancer is not convincing."Dr. Moez Sanaa, Director of Standards and Scientific Suggestions, said, "We need to conduct better research, conduct longer follow -up in the existing queue and repeated diet questionnaire surveys. We need to conduct random control tests, including insulin regulationThe research on the mechanism of metabolic syndrome and diabetes, especially research related to carcinogenicity. "
