Carcinogens detected in 59 coffees such as Luckin Starbucks Recently, the news that "all mainstream coffees such as Fuzhou Luckin and Starbucks have detected carcinogens acrylamide" has attracted attention. The relevant news also topped the hot search on Weibo, causing heated discussions".
According to the content released by the Fujian Provincial Consumer Council, this comparative test sampled 59 ready-made and ready-to-sell coffees from 20 coffee sales units in Fuzhou City (including 30 offline and 29 online), and the samples involved 20 mainstream brands in the market, such as Luckin, Starbucks, Lucky Coffee, and Cotti Coffee, including different categories such as American coffee, latte and flavored latte, basically covering the freshly made and sold coffee products on the market.
Test results: 2 lattes were labeled as "sugar-free", and after testing, the sugar content exceeded the maximum limit value specified by the standard for "sugar-free".In the caffeine testing process, the caffeine content of 4 samples was less than 200mg kg, which was slightly inferior in terms of refreshing effect.
In the detection of protein, fat and other items, the detection amount of most products is relatively stable, which basically meets the requirements of the national healthy diet recommendation, and the milk and dairy products added to coffee are of good quality.
It is worth noting that none of the 59 samples were found to contain trans fatty acids (less than 0.).0013g 100g), but low levels of class 2A carcinogen "acrylamide" were detected (at present, there are no restrictions or prohibitions on acrylamide in coffee in China).
Among the four categories of carcinogens announced by the World Health Organization, acrylamide belongs to category 2a carcinogens, that is, there is limited evidence of carcinogenic effects on humans, and sufficient evidence of carcinogenicity to experimental animals.
So, why does coffee have acrylamide?
Actually, it has to do with the processing of coffee. Green coffee beans contain sucrose and asparagine, both of which produce a Maillard reaction at high temperatures, and acrylamide is one of the by-products of the Maillard reaction.
In general, acrylamide is easy to form when cooked at temperatures higher than 120, and almost always when roasting coffee beans, it is higher than that.
According to the results of a 2010 study in the International Journal of Food and Chemical Toxicology (No. 48), the dose of acrylamide when it causes cancer is 26~16μg/kg.day (1 microgram is 1 millionth of a gram), that is, an adult weighing 60 kilograms, if he consumes 156 micrograms of acrylamide per day (156 micrograms = 2.).6 mcg 60) to reach carcinogenic amounts. (That is, you have to drink 12kg of coffee a day to get the carcinogenic dose).
The content of acrylamide in a cup of coffee will not have much impact on the body, but in addition, coffee will also cause other effects on the body, excessive drinking will affect the absorption of calcium, increase the risk of osteoporosis, make the human body excited for a long time, insomnia, anxiety, and in serious cases, it will also cause depression, memory loss and other problems.
1. Effect on sleep.
Drinking a lot of coffee over a long period of time can have a negative impact on sleep quality. The caffeine in coffee stimulates the central nervous system, making the body feel excited and alert, which can affect sleep.
In the long run, you may find that you have difficulty falling asleep, or that the quality of your sleep decreases, leading to mental exhaustion and difficulty concentrating.
2. The effect of coffee on cardiovascular disease.
Long-term coffee consumption may also increase blood pressure levels. Caffeine stimulates adrenaline secretion, causing blood vessels to constrict, heart rate to increase, and blood pressure to rise. In the long run, this can have adverse effects on the cardiovascular system, increasing the risk of high blood pressure and cardiovascular disease.
3. The effect of coffee on the digestive system.
Caffeine in the digestive system increases stomach acid levels, leading to stomach upset and heartburn. The liver processes excess caffeine in the body and produces urine – drinking a lot of coffee can cause frequent urination. Additionally, people with stomach problems such as ulcers or acid reflux should avoid caffeine.
4. The effect of coffee on teeth.
Drinking coffee for a long time may cause stained teeth, which can affect aesthetics. In addition, the acids in coffee may erode tooth enamel, leading to tooth sensitivity and caries problems.
In conclusion, drinking large amounts of coffee over a long period of time may pose a range of health risks. However, as long as we drink in moderation, pay attention to health measures such as hydration and oral hygiene, and check our physical condition regularly, we can effectively prevent the occurrence of these risks. Let's take a rational look at the health effects of coffee
