Drinking coffee can cause cancer?! Potato chips shake their heads after listening to them!

"Coffee causes cancer! The darker the coffee beans are, the higher the acrylamide content will be!

"recently, after reading a tweet in the family group, the code clerk was silent. First of all, regardless of whether there will be acrylamide in coffee beans after roasting, from the point of view of this substance, it cannot be said that as long as acrylamide is ingested, it will certainly increase the risk of human cancer.

And the starting point of this news almost didn't confuse the code clerk. It started when a Swedish professor first discovered acrylamide, a potential neurotoxic carcinogen, in fried / baked potatoes and grains in 2002. Some documents have shown that this substance is a by-product of the "Maynard / Merard reaction" of food. So the darker the coffee beans are, the higher the risk of cancer is!

WHAT?

Maynard reaction is also the key to aroma and dark color in food processing and cooking. If Maynard reaction produces carcinogens, then eating braised meat is also a carcinogenic process. Because this is the most typical and most common home-cooked dish of the Maynard reaction. What's the reaction? Stir-fry sugar color, or fry the pork belly into an attractive appearance.

Maynard reaction refers to a series of complex chemical reactions between carbohydrates in food and amino acids and proteins after heating. After the reaction will produce melanin and thousands of different odor molecules, these odor molecules can tease the human sense of smell, emitting an attractive flavor.

To put it simply, as long as there are carbohydrates (including starch, sugar) or fats / oils, as well as proteins (amino acids or amines produced by amino acid degradation), the Maynard reaction can be produced with high temperature heating.

The darker the food becomes when heated, the more severe the Maillard reaction is and the more acrylamide is produced. If, as the article said, the fried, fried, braised and other cooked foods we eat in our daily life are to some extent more scorched than coffee beans. And black sugar, which is no stranger to everyone, is probably "cancer-causing cancer".

Some things, can not put aside other more important factors, just change your mind out of thin air! Moreover, acrylamide is widely found in foods that people eat every day, including coffee, chocolate chip cookies, cereals, and even fruits and vegetables.

If you really want to look directly at the final test data, there is acrylamide in coffee, but the average content is 150mg/ kg, while the acrylamide in black sugar is 860mg/ kg. If you look at it this way, black sugar is much scarier than coffee.

Of course, we can't make such a direct comparison!

According to the study, even for the same food, the content of acrylamide varies greatly due to subtle differences in the way it is processed. But overall, fried potatoes are the main foods with high acrylamide content, while vegetables and fruits are lower. In addition, temperature has a great influence on the content of acrylamide.

The critical temperature for the formation of acrylamide is 120 ℃, in a certain temperature range (
