Coffee may lower the risk of several types of cancer, according to recent studies reviewed by researchers at the American Cancer Society.

To learn more about science, coffee, and why the research matters, join the experts from the NCA Scientific Leadership Council for “The Coffee Science Fair: A Fun Look at a Serious Topic,” a special educational session at the NCA 2019 Convention in Atlanta, GA on March 8.


Scientists have been investigating the links between coffee and cancer for decades. And while our understanding of coffee’s potential health benefits has improved with advances in research, there’s still more to learn.

In 2016, an expert panel convened by the International Agency for Research on Cancer (IARC) — the arm of the World Health Organization that is responsible for assessing whether certain substances cause cancer — could not conclude that drinking coffee is carcinogenic based on the current evidence available.

Yet the coffee-cancer connection has recently reappeared in the news, due to the ongoing Prop 65 legislation in California to put misleading “cancer warning labels” on coffee.

So, what do coffee drinkers need to know?

In following interview written by Elizabeth Mendes, American Cancer Society researchers Susan Gapstur, PhD, and Marjorie McCullough, ScD, explain what the studies really show when it comes to coffee and cancer, and discuss what other research is still needed.

A “Common Sense” Victory For Coffee Science in California

“Call it a victory for science — or maybe just for common sense.” – The Seattle Times


It was a good news week for  coffee science in California.

Earlier this month, OEHHA (the state’s Office of Environmental Health Hazard Assessment agency) proposed a plan that would exempt coffee from Prop 65 required “cancer warning labels” in California after the most recent ruling in the ongoing legislation.

The statement was met with resounding support from scientists and coffee lovers alike.

“OEHHA’s Rulemaking is supported by both the full weight of scientific evidence and law,” wrote William “Bill” Murray, NCA President and CEO, in comments filed Aug. 30. The letter commended the decision and laid out the strong case for coffee in a scientific summary signed by Dr. Mark Corey, NCA’s Director of Scientific & Government Affairs, and Dr. Alan Leviton, Consultant to the NCA Scientific Advisory Group.

Simply put, the research speaks for itself: coffee does not cause cancer.

Then this week, in a groundbreaking announcement, the U.S. Food and Drug Administration sent a letter to Sacramento which emphatically set forth their support for this rule.

Coffee, Acrylamide, and Your Health

A guide to California’s Prop. 65 and ongoing labeling legislation for the informed coffee drinker.

Overwhelming research shows that regular coffee consumption may be linked to a host of potential health benefits, from liver health to longevity. 

Scientists believe that the secret lies in coffee’s complex chemistry: There are at least 300 natural compounds in one green bean, and about 1,000 more created in the roasting process – including  caffeine (of course), antioxidants, and minerals.

Together, the various things that make up coffee create a delicious brew that can be part of a healthy lifestyle. 

However, a long-running lawsuit under California’s controversial Prop 65 regulation has sought  to force coffee companies to include “cancer warning labels” on coffee package labels and in coffee shops.

Two big studies support the long-term health benefits of coffee

It turns out, a cup of coffee can do a lot more than just perk up your morning.

People who drink more coffee may have a lower risk of premature death from disease, according to two new studies published in the Annals of Internal Medicine. The results were consistent among more than 700,000 participants from a variety of racial, ethnic, and cultural backgrounds.

Previous research has suggested that coffee is good for you, but was often limited to smaller groups and people of European decent, writes the Los Angeles Times.

And both studies found benefits for people who drank decaffeinated as well.

People who drink more coffee are “significantly” less likely to develop liver cancer, according to a new study published in the journal BMJ Open. These findings support increasing evidence that coffee may have protective benefits for liver health, and may even counteract damage from alcohol consumption.

Nervous About Caffeine? Don’t Be.

What you need to know about the latest research on coffee and your health.

An unprecedented scientific review on caffeine safety confirms that drinking up to four cups of coffee daily, or about 400 milligrams of caffeine, is “not associated with overt, adverse effects” in healthy adults. (Pregnant woman and minors should reduce their intake below that amount, according to the report.) [1]

The review was conducted by the International Life Sciences Institute (ILSI), and is the most extensive of its kind to date. Scientists scoured data from more than 700 independent studies related to various human health effects and caffeine.
