Coffee May Curb Liver Cancer


(WebMD) Could a cup of coffee cut your risk of developing liver cancer? Maybe, but don't bet your next latte on it just yet.

A new report, published in the August edition of the journal Hepatology, boils down the findings from 10 studies on coffee and liver cancer.

The studies were reviewed by researchers including Francesca Bravi, ScD of the Istituto di Ricerche Farmacologiche "Mario Negri" in Milan, Italy.

Together, the studies included 2,260 people with liver cancer and nearly 240,000 people without liver cancer. Participants lived in Greece, Italy, or Japan.

Participants reported their coffee-drinking habits. The data show that coffee drinkers were 41 percent less likely to have been diagnosed with liver cancer than people who don't drink coffee. For every daily cup of coffee people drank, their odds of having been diagnosed with liver cancer dropped by 23 percent, compared with people who never drink coffee.

People who drank a lot of coffee were 55 percent less likely to have been diagnosed with liver cancer than those who didn't drink any coffee.

What's a lot of coffee? That depends on which of the 10 studies you look at. Some of the studies defined high coffee consumption as three or more daily cups. Others set the bar lower, at more than one daily cup.

The fact that liver cancer was rarer among coffee drinkers a world apart — in Greece, Italy, and Japan — suggests that the coffee findings weren't a fluke or a local phenomenon, note Bravi and colleagues.

They speculate that coffee perks up liver enzymes and may cut cirrhosis and liver cancer.

But Bravi's team doesn't promise that drinking coffee will prevent liver cancer. They note that people with various digestive and liver diseases might choose not to drink coffee for reasons that aren't reflected in the data.

Whether or not coffee prevents liver cancer "remains open to discussion," write Bravi and colleagues.

Tea Party vs. Coffee Party

Tea Party vs. Coffee Party

The Tea Party now has a challenger--for media attention, at least. A new organization called the Coffee Party is touting a pro-federal government, anti-obstructionist platform. On its Facebook page, the Coffee Party movement explicitly positions itself as an answer to the Tea Parties. For example:

The Coffee Party doesn't just think Tea Partiers are unhelpful. The party thinks they're a threat to the democratic process, and suggests it's a civic duty to oppose them. Their mission statement announces that Coffee Partiers will "recognize that the federal government is not the enemy of the people, but the expression of our collective will." This mission includes building up a grassroots base, electing positive leaders, and "hold[ing] accountable those who obstruct them."

Many Americans reject the idea of working with the federal government or participating responsibly in the democratic process. For whatever reason, they have declared war on our government, and on our President. This is a destructive path.

Climate Change Presents A Burr For Coffee Growers

Disaffected Democrats, craving a grassroots movements of their own, are organizing the "Coffee Party." Here's an instant guide.

http://media.npr.org/assets/news/2010/03/22/coffeebeans.jpg?t=1269262423&s=2
A man holds a handful of coffee beans during the first day of the World Coffee Conference in Guatemala City on Feb. 26. Coffee producers say they are getting hammered by global warming, with higher temperatures forcing growers to move to prized higher ground, putting the cash crop at risk.

The effects of climate change may be coming to your coffee cup.

The plants that produce coffee beans are notoriously sensitive, and small changes in temperature and precipitation can have big impacts on coffee quality and quantity. It may cause connoisseurs to cringe, but a warmer climate will encourage more coffee farmers to plant the heartier robusta varieties, which are caffeine-rich but bitter, instead of the mild, tasty Arabica coffees that Americans prefer.

"I often call coffee a Goldilocks plant. It likes it not too hot, not too cold. It likes it not too wet, not too dry. It doesn't like too much sun, it doesn't like too much shade," says Peter Baker, who studies coffee for the nonprofit CABI Bioscience. "The conditions are really quite limiting, and farmers have a real struggle, as we've seen in Colombia this last year or so — they've had the heaviest rainfall in recorded history really."

Growers recently gathered at the World Coffee Conference in Guatemala to discuss how the possibility of a warming planet could affect growing conditions and to figure out how to prepare.

Not far away, beneath two volcanoes in Guatemala's Antigua Valley, sits San Sebastian farm. The owner, Eduardo Falla, says his coffee's award-winning flavor is a factor of the rich volcanic soils — and the climate.

"The microclimate we have is special," Falla says, using a wooden rake to turn coffee beans drying in the sun. "The temperatures rise, more or less, to 79 degrees and fall to 50 degrees at night. This is part of what gives it the quality."

So as it gets warmer, one strategy would be to move coffee production to cooler regions.

"You can move up the mountainside as it gets warmer," Baker says, "but you actually run out of space, because mountains have this unfortunate property of being pointed."

In Colombia, heavy rains cut coffee production by one-quarter last year, so the country has stepped up its weather monitoring. The national center of coffee research now has more than 200 meteorological stations to better forecast weather conditions, advise farmers and document climate trends.

The rains were associated with a strong La Nina weather pattern, which can't be blamed directly on climate change. But Baker says the record rainfalls are consistent with the generally more chaotic weather that climate models predict.

Brazil, the world's largest coffee grower, is also planning ahead for a changing climate.

Eduardo Assad of the Brazilian Agricultural Research Corp. says warm temperatures can cause coffee to flower early, reducing productivity. "The problem of coffee in Brazil is if you increase the temperature, you have problems of the flowering — this is the first problem," he says. "The second problem is the water deficits."

Assad says Brazilian researchers are trying to develop coffee hybrids better adapted to warmer and drier conditions, but that could take years. Alternatively, the coffee farms might have to move.

"We have 2 million hectares of coffee in Brazil, and with the new scenarios of climate change, maybe this production can go to the south of Brazil," he says.

Back under the volcanoes in Guatemala, Falla looks over some of his coffee plants that have flowered — but only on half of the branches.

Rain that fell two weeks earlier was insufficient, Falla says. If it doesn't rain again soon, he'll be forced to irrigate to stimulate more flowering. Growing coffee is an uncertain occupation, he says, and climate change adds yet another variable to the mix.




The office coffee is more important than it seems

.

Editor's Note: After reading about the office coffee conundrum, take our survey: How do you like your coffee?

Nathan Hartland was at Caribou Coffee in downtown Baltimore recently, picking up a cappuccino on his lunch hour. His 3-year-old son had awoken in the middle of the previous night, leaving a sleep-deprived Hartland in need of a serious jolt of caffeine.

“I’m here to make sure I’m awake through the afternoon,” said Hartland, a lawyer at Miles & Stockbridge. He could have had a cup of free coffee at the office, but opted not to.

“I don’t enjoy it — and it also gives me a headache,” said Hartland, who prefers cappuccino because it doesn’t leave his head throbbing like regular or decaf coffee.

Clearly, people have strong preferences when it comes to their java, which can complicate things for employers who offer coffee in the workplace.

We usually don’t think much about that cup of Joe — other than whether to opt for skim milk or cream; sugar or Equal. But workplace experts say that depending on how it is handled, coffee can either be a perk that fuels employee morale or an annoyance that steams up workers to the point where they feel alienated and disgruntled.

Think of the person who consistently gets stuck having to brew a fresh pot because a sneaky co-worker always makes off with the last cupful. Or the decaf drinker who feels left out in an office that offers only regular coffee.

“Variety is very important,” said Deborah Diehl, a partner at law firm Whiteford, Taylor & Preston, which offers several different coffees. “There are certain attorneys who, if the French roast is out, are not going to have a good day.”

Some workers are so dedicated to their favorite brand of coffee, they’d rather dig into their pocket to buy their own coffee than settle for what’s available at the office for free.

On a recent weekday, Cory Stokesberry was heading back to the downtown construction company where he works as a project manager, a Starbucks coffee in hand.

Stokesberry moved to Baltimore from Seattle — the home of Starbucks — five months ago. Coming from the Emerald City, a place where the aroma of coffee pervades the air and there are downtown streets with a coffee shop on every corner, Stokesberry was overjoyed when he finally found a Starbucks in downtown Baltimore.

“It’s not even comparable,” he said of the comparison between Starbucks and his office’s coffee.

Joyce Russell, an industrial and organizational psychologist who consults for private companies and government agencies, said what seems like a trivial matter — such as who cleans the office coffee pot — can loom large these days because workers at many companies may already be feeling frazzled from being overworked.

“If there’s already a collaborative environment, this won’t be much of a stresser,” said Russell, who teaches courses in leadership and organizational behavior at the University of Maryland’s Robert H. Smith School of Business. “But if people are already feeling stressed, this won’t help.”

Workers tend to view how a company handles the little perks as a symbol of how much they care about their employees, said Filiz Tabak, a professor of management and leadership at Towson University’s College of Business and Economics.

If handled correctly, free coffee and other small benefits can turn into an advantage because it makes workers feel better about their company, reducing employee turnover and making it easier to recruit new workers.

“If I’m in a company where my well-being counts, I’m going to talk about it to my friends and their friends,” Tabak said.

So employers should think twice before deciding arbitrarily to save money by switching to a less expensive brand of coffee or eliminating it altogether, said Russell, the organizational psychologist. If a change needs to be made, workers should be included in the decision-making process, she said.

That’s what Whiteford, Taylor & Preston did when it decided to switch coffee vendors several years ago.

The firm set up an array of coffees from different suppliers in a conference room and let workers have their say about which they liked best. That made workers feel appreciated, said Tracy Canady, a collections specialist who favors French vanilla.

To handle the decaf versus regular conundrum, when the firm redid its downtown Baltimore offices about three years ago, it went from communal coffee pots, one for decaf and one for regular, to single-serve Flavia coffee machines on its employee floors.

Instead of using a coffee pot, the Flavia machines use single-serve coffee packets that are inserted into the machine to make individual cups of coffee.

That means workers get the variety they want without having a coffee pot to clean.

On a recent Wednesday, the offerings included hot chocolate and seven types of coffee ranging from cappuccino latte swirl to house blend decaf.

Coffee is an important part of the social fabric, in the office and elsewhere.

“If you’re talking to clients, it’s the first thing you offer them,” said Alexander Koff, who heads Whiteford, Taylor & Preston’s global practice.

Corby Kummer, a senior editor at the Atlantic Monthly and the author of book “The Joy of Coffee,” is generally no fan of office coffee, however. It tends to be too weak, or too bitter, because it has been left on the burner too long, he said.

“So often you get something that reminds you of what Abraham Lincoln told a waiter,” Kummer said. “ ‘If this is coffee, bring me tea, and if this is tea, bring me coffee.’ ”
