A regular intake of coffee has also been linked to a lower risk of dementia, Alzheimer’s, Parkinson’s, and type 2 diabetes (
To top it off, coffee drinkers seem to live longer (
However, coffee also contains a potentially harmful chemical called acrylamide.
体育投注网址This article reviews whether you should be concerned about acrylamide in coffee.
Every day you’re exposed to acrylamide through smoking and secondhand smoke, as well as personal care products and household items.
In 2002, Swedish scientists also discovered the compound in a wide range of foods, including baked goods and coffee (
Scientists believe the acrylamide in food is a product of the Maillard reaction. This reaction occurs when sugars and amino acids are heated above 248°F (120°C) (
What is known is that when coffee beans are roasted, acrylamide is formed. There’s no way to remove it from coffee, so when you drink it, you’re exposing yourself to the chemical (
体育投注网址Acrylamide is a potentially harmful chemical formed during the coffee bean roasting process.
体育投注网址Studies in animals have also repeatedly shown that high amounts of acrylamide can cause cancer when eaten.
体育投注网址However, the doses given to animals have been 1,000–100,000 times larger than the amounts humans are exposed to through diet.
Humans also metabolize acrylamide differently, so you’re exposed to a lower dose of the chemical when your body breaks it down (
Still, there are few human studies on the safety of acrylamide in food, and the results have been inconsistent (
体育投注网址It’s also important to keep in mind that acrylamide is not a new problem. Despite only recently being discovered in food, it’s likely to have been there in some amount since humans started cooking.
Workplace exposure to high amounts of acrylamide can cause nerve damage. In very high doses, acrylamide is known to cause cancer in animals. Not much is known about whether it’s safe for humans.
Here are the average amounts of acrylamide they found in each type of coffee:
体育投注网址They also noted that acrylamide levels peak early in the heating process and then decline. So lighter-colored coffee beans have more acrylamide than darker ones that are roasted longer.
The amount of acrylamide in coffee can vary greatly. Well-roasted, dark, fresh coffee beans are likely to have the lowest amount.
For example, in one study, people who increased their coffee intake by 2 cups (475 mL) per day had a 40% lower risk of liver cancer (
Coffee drinking is also linked to a plethora of other health benefits, such as living longer体育投注网址 and a reduced risk of many diseases.
体育投注网址Coffee hasn’t been shown to increase your risk of cancer. In fact, it has been linked to a reduced risk of some types of cancers, such as liver cancer.
While it’s not possible to buy coffee that’s completely free of acrylamide, the coffee industry is working on practical solutions to reduce its presence (,
Given the potential health benefits of coffee, it’s not something you need to cut out.
Coffee contains many other chemicals that may be beneficial to your health. Cutting it out isn’t necessary.
There’s no evidence that small amounts of dietary acrylamide cause harm.
However, if you’re concerned, here are a few steps you can take to minimize your exposure:
体育投注网址Completely avoiding acrylamide is impossible. However, you can make a few changes to reduce your acrylamide intake.
