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.

Coffee and Cigarettes: Misinformation By Algorithm

Despite overwhelming scientific evidence, popular myths on coffee and health continue to persist.

By Kyra Auffermann, NCA Digital Content & Communications Manager


Coffee plays an important role in the lives (or at least mornings) of most people — in the United States, nearly 80% of all adults drink coffee, typically at the start of their day.

Yet most coffee drinkers don’t have a good understanding of coffee: the plant, the way it is processed, or the precision of a “perfect” roast.

In fact, more coffee drinkers may have a good misunderstanding of coffee. And despite overwhelming evidence, myths persist — particularly when it comes to coffee and health.

Coffee Clickbait Goes Bananas

New research on coffee and climate change indicates an urgent situation for crops at origin

Behind the headlines on the future of coffee, according to science – and how you can get involved.

Complete with the typical clickbait-style headline, a recent article intoned that the global population is imminently doomed to a world without coffee – and “not much” can be done about this “on a personal level.”

Sounds grim.

But it could be easy to miss the glimmer of hope buried in the last line:

This future could look bleak for morning coffee drinkers, but with the help of farmers and scientists, our cup of joe can be protected.”

Coffee: The Best Health Habit of All?

What science can teach us about coffee.

By Dr. Bob Arnot, author, The Coffee Lover’s Bible


Coffee may be the greatest nutritional miracle in our world today. What other delicious beverage gives you such a bright, optimistic outlook while making a tremendous impact on your overall health, well-being, and longevity?

Coffee is also one of the greatest indulgences, a sensory experience that rivals the best wines. How else can you make such a robust improvement with such minimal effort. That wasn’t always the case.

I’ve written more than a dozen books on nutrition including two on Coffee. When I was chief medical correspondent for Dateline NBC, Today, NBC Nightly News, and CBS Evening News from the 1980s into the 2000s, and most recently as a contributor on Dr. Oz, we were always on the lookout for the next great nutrition story.

Ironically, we were alert to stories about why coffee was bad for you. At that time, coffee had a reputation for causing harm, and most people feared that it was unhealthy.

Why?

Forcing Unfounded Cancer Warnings On Coffee Labels Is Unconstitutional, Says Legal Expert

Two paper cups unfocused one in focus isolated blank package

Compelled speech, like censored speech, can violate the Constitution, according to legal experts.

By William “Bill” Murray, CAE, NCA President & CEO via LinkedIn

“Forcing [coffee companies] to include a cancer warning on a product that does not cause cancer plainly violates the 1st Amendment.”

So states legendary First Amendment lawyer Floyd Abrams (Pentagon Papers, Citizen United), in today’s Los Angeles Times Op-Ed.

Why the Latest Prop 65 Ruling is Bad for Coffee Farmers

Coffee is both delicious and healthy.”

California’s Misguided Labeling Decision Impacts Coffee Growers & Drinkers

This post was originally published on the Global Farmer Network

By Luiz Roberto Saldanha Rodrigues

When a Los Angeles judge earlier this month finalized a ruling that coffee sold in California must carry cancer warning labels, many California residents may not have paid much attention to yet another labeling requirement.   

Ever since voters passed Proposition 65 more than 30 years ago, after all, Californians have watched the steady proliferation of vague statements about chemicals, cancer, and birth defects. They appear almost everywhere, from the windows of hardware stores to signs at Disneyland. They’re so abundant that Amazon even sells them as stickers in rolls of 500.  

Many people have begun to ignore these labels because they’re so common and because the information they convey is almost useless.  

So why am I  concerned if they now also show up on coffee?
