Has your circle of friends been brushed by a message?

"Drinking coffee=causing cancer"

The coffee you know

The cancer you know

Main content forwarded by everyone

 

A few days ago, Fujian Provincial Committee of Consumer Affairs carried out a comparative test on 59 types of ready to sell coffee from 20 coffee sales units in Fuzhou. Low content of Class 2A carcinogen was detected in all samples, including Ruixing and Starbucks

The low content of 2A carcinogen "acrylamide" was detected in the 59 samples (at present, China has no restrictive or prohibitive regulations on acrylamide in coffee).

 

The news spreads quickly

It suddenly caused panic among many coffee fans

Is it really that serious to have a cup of coffee?

Let's make a rumor first

"Drinking coffee=causing cancer"

False!!!

 

Everyone is about to say, it doesn't say

In coffee Contains potential carcinogens Acrylamide

Then why "Drinking coffee=causing cancer" It's fake

The content of the article is too rich. Let's summarize first

 

1. Coffee does contain potential carcinogens Acrylamide But it's not just coffee.

2. Fried food is the main source of acrylamide, It's true to eat less fried food 。

3. Although the coffee contains acrylamide The amount of coffee consumed by normal people is far from carcinogenic.

——Coffee is still drinkable!

This will sort out the context for you.

 

First, let's take a look

What is acrylamide?

Among the four categories of carcinogens published by the World Health Organization, acrylamide belongs to category 2A carcinogen, which means that there is limited evidence of carcinogenic effect on humans and sufficient evidence of carcinogenic effect on experimental animals.

A large number of animal experiments show that acrylamide is carcinogenic and can cause damage to the nervous system. Many epidemiological studies have shown that acrylamide is related to kidney cancer, endometrial cancer, head and neck tumors, but these carcinogenicity is only "suspected".

 

How is acrylamide produced?

Acrylamide is mainly produced in the process of food processing. When reducing sugar (carbohydrate) in food and amino acid (mainly asparagine), the hydrolysate of protein, are heated, a complex chemical reaction called Maillard will occur. Acrylamide is formed from this.

 

Which foods are easy to produce acrylamide?

According to the principle of Maillard reaction, as long as the ingredients contain more carbohydrates (such as sugar and starch) and proteins, Maillard reaction will occur during high-temperature processing (120 ℃~185 ℃), and acrylamide will be produced. therefore A large number of fried, fried and baked foods, such as coffee, French fries, fried dough sticks, bread, twist, biscuits, potato chips, barbecues, etc., may contain acrylamide , the greater the color change after processing, If the food is yellow, brown and zoomed, the content of acrylamide will be higher.

Content of acrylamide in different foods

In 2005, the Expert Committee (JECFA) jointly established by FAO/WHO counted 6752 test data from 24 countries and calculated acrylamide content according to food category as shown in the table below.

Does acrylamide really cause cancer?

According to a research result in the 2010 International Journal of Food and Chemical Toxicology (Issue 48), the dose of acrylamide for carcinogenesis is 2.6~16 μ g/kg.day (1 microgram is 1 millionth of 1 gram), That is, if an adult with a weight of 60 kg takes 156 micrograms of acrylamide (156 micrograms=2.6 micrograms × 60) every day, it will reach the level of carcinogenesis.

 

According to the above table, the average content of acrylamide in brewed coffee is 13 μ g/kg, That is to say, it takes 12 kg of coffee every day to drink a carcinogenic dose. Can we really drink 12 kg of coffee every day? The answer is obvious.

 

The acrylamide detected in the experiment is very low

Safe!

In the comparison test mentioned at the beginning, the acrylamide content in coffee is converted into cups for calculation. The acrylamide content in coffee is 3.39-10.20 µ g/cup. The intake of a cup of coffee every day is within the safe range. As long as it is not drunk excessively for a long time, there is no obvious health risk to the human body.

If you leave the dose, the toxicity is all hooliganism

The same is true of carcinogenicity

Generally, the intake of acrylamide containing

Coffee, fried dough sticks, cookies, potato chips, bread and other foods

Not so easy to cause cancer

But control it properly

The intake of harmful substances is always right!

 

How to avoid acrylamide?

Acrylamide, as the companion of a kind of delicious food, is neither a devil nor an angel. But in our daily life, we should pay attention to the following points while enjoying delicious food:

1. Eat less fried potatoes such as French fries, French fries, French fries, etc;

2. Eat less fried noodles such as fried dough sticks and thin crisps;

3. Eat less baked foods such as biscuits, cookies and crackers;

4. Eat less barbecue food.

 

If it is difficult to completely avoid the above food, some small details in life should also be noted:

1. When cooking, more cooking and stewing, less frying, frying and roasting;

2. Drink less coffee and more tea at ordinary times;

3. Children, pregnant women and lactating mothers should pay special attention to drinking less coffee.

In short, eat less high temperature fried food, eat more fresh vegetables and fruits, better health.

 

I believe that through this article

You know, for Acrylamide Will have some understanding

Not to mention its color change

 

Finally, for you who love coffee

Know ↓

How should I drink coffee?

Pay attention to the following details

Reduce the adverse risk of drinking coffee:

01

Remember control quantities

Zhu Renshan, health ambassador of Fujian Health News and registered dietitian of Union Medical College Hospital affiliated to Fujian Medical University, said that coffee contains caffeine, which cannot be ignored. Therefore, considering various factors, the daily intake of coffee should be controlled at 0.5-3 cups.

Avoid these moments

02

It is best not to drink coffee on an empty stomach or in an emergency. Don't drink after 5:00 or 6:00 in the afternoon to avoid insomnia and excessive urination.

03

Try to choose black coffee

Zhu Tianshan suggested that black coffee be the best choice for drinking coffee, and instant coffee should be avoided for a long time. You can also choose hand brewed coffee, milky espresso, raw coconut coffee, but caramel macchiato or mocha with syrup or chocolate syrup are not recommended.

Special people drink less or no

04

Children and adolescents, pregnant women and lactating women, patients with osteoporosis or digestive tract diseases, people who are sensitive to caffeine, and those who suffer from insomnia, try not to drink or drink less coffee.

 

It's very kind of us to attach
