Instant Coffee and Cancer Risk: What the Science Says

You’ve seen the headlines: “Instant coffee is more carcinogenic than cigarettes!” But is there any truth to the claim that your daily instant cuppa is a major health hazard? A widely shared article claimed that instant coffee contains higher levels of the chemical acrylamide—a known potential carcinogen—than fried snacks and even tobacco. That sounded alarming. But how accurate is it really?

The short answer: No, instant coffee does not present a higher cancer risk than smoking. While both contain acrylamide, experts confirm that the levels in coffee are far lower and the overall risk is minimal—especially compared to the well-established dangers of tobacco. Most people also consume coffee far less frequently than cigarettes, further reducing any comparative risk.

What Is Acrylamide and Why Is It in Coffee?

Acrylamide is a chemical that forms naturally when certain starchy foods are cooked at high temperatures—typically above 120°C (248°F)—through a process called the Maillard reaction. This includes foods like fries, chips, toast, and yes, coffee beans, whether they’re roasted for instant or ground coffee.

In coffee, acrylamide forms during the roasting process, not the brewing. It’s found in both instant and freshly ground coffee, though levels can vary based on roast degree and bean origin. The concern arises because acrylamide is classified by some health authorities as a “potential human carcinogen,” based mainly on animal studies.

How Does Instant Coffee Compare to Other Foods?

According to the original viral article, instant coffee was said to have higher acrylamide levels than four other common foods: potato chips, french fries, cakes, and cigarettes. But that comparison lacks important context.

While it’s true that acrylamide is present in all these items, the concentration and exposure levels differ significantly. For example:

• Fried starchy foods like chips and fries are major dietary sources of acrylamide due to high-heat cooking.
• Cigarettes are a well-established source of multiple carcinogens, with acrylamide being just one of many harmful chemicals.
• Instant coffee does contain acrylamide, but typically at lower exposure levels than heavily processed snack foods.

Importantly, the International Agency for Research on Cancer (IARC) has classified acrylamide as a “Group 2A probable carcinogen,” but it’s important to note that this classification is based largely on animal studies, not conclusive human evidence.

What Do Food Safety Experts Say?

Zhang Ying, a professor at Zhejiang University’s College of Food Science and Technology, weighed in on the controversy. She clarified that while both instant coffee and cigarettes contain acrylamide, they are not directly comparable in terms of health risk.

“Smoking is definitively linked to cancer and is recognized as a major risk factor by the World Health Organization,” Professor Zhang said. “The acrylamide in instant coffee is classified as a potential carcinogen, but the actual risk it poses to humans is much lower.”

She also emphasized moderation. “Whether you’re drinking instant or freshly brewed coffee, limit your intake. A safe upper limit is no more than five cups or packets per day.”

Frequently Asked Questions

Is acrylamide in instant coffee dangerous?

Acrylamide is classified as a potential carcinogen, but the levels found in instant coffee are generally low and not conclusively linked to increased cancer risk in humans. The overall exposure from coffee is much lower than from other dietary sources like fried starchy foods.

Does instant coffee have more acrylamide than regular coffee?

Both instant and freshly brewed coffee contain acrylamide, which forms during roasting. Some studies suggest instant coffee may have slightly higher levels due to differences in processing, but the difference is usually minor and not definitively established.

Is smoking worse than drinking coffee for cancer risk?

Yes. Smoking is a well-established cause of multiple cancers and is universally recognized as highly carcinogenic. The acrylamide in coffee, while potentially concerning in very high doses, does not compare to the risks posed by tobacco.

How much coffee is safe to drink per day?

Experts recommend limiting coffee intake to no more than five cups or packets per day, whether instant or freshly brewed, to stay within safe exposure levels for acrylamide and other compounds.

Should I stop drinking instant coffee because of acrylamide?

There’s no need to stop based on current evidence. Moderate consumption of instant coffee is considered safe for most people. If you’re concerned, you could alternate with other brewing methods or reduce frequency.
