Detect carcinogens! Many people drink it every day …

The Consumer Council of Fujian Province conducted a comparative test on 59 types of coffee made and sold in 20 coffee sales units in Fuzhou, and all of them detected low levels of Class 2A carcinogens. The samples involved Ruixing and Starbucks …
Seeing this "deadly" news
How many people are like Xiaobian?
Immediately put down his hand.
Coffee used to "prolong life" …
However, there is a famous saying in the "scientific community"
"Leaving the dose to say that toxicity is hooliganism"
Why don’t you have a cup of coffee to refresh yourself
Take a closer look at the news
What the hell is going on?
Partial sampling sample
In this comparative experiment, 59 types of ready-made coffee sold in 20 coffee sales units in Fuzhou were sampled (including 30 offline and 29 online). The samples involved 20 mainstream brands in the market, including American coffee, latte and flavor latte, which basically covered the ready-made coffee products sold in the market.
In this comparative experiment, eight items, such as energy, carbohydrate, protein, fat, trans fatty acid, total sugar, caffeine and acrylamide, were tested. Judging from the results of this test:
No trans fatty acids were detected in the 1.59 samples (below the detection limit of 0.0013g/100g).
2. In the detection of protein, fat and other items, the detection amount of most products is stable, which basically meets the requirements of national healthy diet recommendation, and the quality of milk and dairy products added in coffee is good.
3. In the testing items of energy, sugar, caffeine, acrylamide, etc., the testing results of each product are quite different, which is worth studying and discussing and paying attention to by consumers.
Among the 59 samples, the energy test results are high and low, and the energy of a cup of coffee is higher than 1/6 of the energy needed by an adult woman in a day; There are two kinds of American coffee and two kinds of lattes labeled as "sugar-free" in the samples, but after testing, the sugar content of two kinds of lattes exceeds the maximum limit stipulated by the standard for "sugar-free"; Caffeine detection showed that the caffeine content of four samples was less than 200mg/kg, which was slightly inferior in refreshing effect.
It is worth noting that
In this 59 samples,
Low levels of class 2A carcinogens were detected.
"acrylamide"
At present, China has not been interested in coffee
Acrylamide has restrictive or prohibitive provisions.
Then acrylamide
What exactly is it?
Can acrylamide cause cancer?
Acrylamide is mainly produced in the process of high temperature treatment of some foods. In 2002, it was first reported by Swedish researchers that a large amount of acrylamide would be produced in fried or baked food. Acrylamide content in food is influenced by many factors.
Food (especially plant food rich in carbohydrates and low in protein) will be naturally produced in large quantities under the cooking condition of > 120℃, which is less produced when boiled with water, and the content in uncooked food is very low.
Among the four kinds of carcinogens published by the World Health Organization, acrylamide belongs to Class 2A carcinogen, which means that there is limited evidence of carcinogenicity to human beings. Many epidemiological studies have shown that acrylamide is related to kidney cancer, endometrial cancer and head and neck tumors, but these carcinogenicity are only "suspected".
According to a research result of International Journal of Food and Chemical Toxicology (No.48) in 2010, the dose of acrylamide causing cancer is 2.6~16μg/kg.day(1 microgram is one millionth of 1 gram), that is, if an adult weighing 60 kilograms ingests 156 micrograms of acrylamide every day (156 micrograms = 2.
Make coffee according to the rules.
The average content of acrylamide is
13μg/kg for conversion.
That is to say, you need to drink 12kg of coffee every day.
To drink a carcinogenic dose
We can really do it every day
Have you finished drinking 12kg of coffee?
The answer is not scary.
But properly control the intake of harmful substances.
It is always right!
In view of the results of this comparative test, the Consumer Council of Fujian Province and the Consumer Council of Fuzhou City issued a consumption reminder to remind consumers that the freshly made and sold coffee tastes mellow and rich, but it is not suitable to drink more, so it should be drunk scientifically and reasonably. Pay attention to the following points when buying ready-made coffee:
First, consumers should learn some basic coffee knowledge before consuming coffee, such as the classification and differences of common coffee (such as American coffee, cappuccino, latte, mocha, etc.), understand the differences between Arabica and Robusta coffee beans, and pay attention to the relatively high energy and sugar content of coffee with milk, flavor syrup and other raw materials.
Second, when purchasing coffee, consumers should pay attention to check whether there are any warnings such as sugar and caffeine on the merchant menu or take-away platform options, and choose the appropriate coffee products according to personal tastes and physical conditions. Pregnant women, lactating women, children, adolescents and other sensitive groups should try not to drink or reduce their coffee consumption.
Third, don’t drink too much coffee for a long time. According to the safe intake of caffeine per day, it is not more than 400mg, generally 1 to 2 cups per day, which is safer. At the same time, coffee contains caffeine, oxalic acid and other substances. Excessive drinking will affect the absorption of calcium, increase the risk of osteoporosis, make people excited for a long time, insomnia, anxiety, and even cause depression, memory loss and other problems.
Fourth, develop a correct way to drink coffee. Usually, the water temperature of drinking coffee should be well controlled, and it is best not to exceed 65 degrees, otherwise it will affect the oral mucosa, gastrointestinal mucosa and even cause mucosal damage. Pay attention to the time of drinking coffee, try to choose after meals, and avoid drinking coffee before going to bed at night or on an empty stomach in the morning. It is not advisable to drink coffee after drinking. People will enter a state of high spirits after drinking. If they drink coffee again, it will only aggravate the excited state of the human body and do great harm to human organs.
