Coffee is officially off the vice list as new studies show health benefits for ailments ranging from cancer to Parkinson's disease
I am not, by nature, a morning person. So ever since the age of 20, I have been a proud member of Coffee Achievers of the World--people whose daily intake of Morning Joe is an essential factor in getting the brain and body kick-started in the morning (or mid-afternoon, or before a college all-nighter). Getting a cup of coffee in the morning is such a high priority for me, in fact, that when I climbed a mountain high in the Himalayan mountains, I took a zip-lock bag of Coffee Singles along with me. I could handle yaks, glaciers, and whatever other discomforts the day had to throw at me, as long as I could start it with a steaming hot cup of Java.
As a result, I have also spent the past decades periodically defending my habit to non-coffee-drinking friends and the occasional health-fanatic doctor--because, as we all knew, coffee was bad for you. "Look," I'd tell the critics. "I don't have many vices. So I'm very attached to the few I have."
Well, huzzah and hurrah, all that is changing!
In a study published Tuesday in the Journal of the National Cancer Institute, a group of Harvard researchers announced that they'd found that coffee consumption actually reduces the risk of prostate cancer, and particularly lethal prostate cancer, in men. Not only that, but a Swedish study published last week in Breast Cancer Research indicates that coffee could also help reduce a woman's risk for post-menopausal, ER-negative breast cancer.
All of that is in addition to other recent studies that have found links between coffee consumption and a decreased risk of gallstones, type 2 diabetes, and Parkinson's disease, as well as lower rates of disease progression in liver cancer and cirrhosis. Other recent studies have indicated that coffee may not even increase a person's risk of heart disease or stroke. Turns out that coffee contains antioxidants and compounds that can improve glucose metabolism and insulin secretion. It also seems to have an effect on sex hormones, which is why researchers looked at its impact on prostate and breast cancer.
There are caveats to the results, of course. The strong correlation in the Harvard study came from men who drank six cups of coffee a day, and the Swedish study results applied to women who drank five or more cups of coffee a day. What's more, a German study (the MARIE study) that was used to validate the Swedish research findings did not show a statistically significant link between coffee consumption and a reduced risk of breast cancer--a result the Swedish researchers think may have to do with the fact that Swedish coffee is boiled, while German coffee is filtered. Of course, boiled coffee has also been shown to raise cholesterol levels, so drinking huge amounts of Swedish coffee in an effort to ward off ER-negative breast cancer might not be such a terrific idea. The Swedish paper also notes that the scientific community is still divided in its opinion of the toxicity of coffee.
But still. How has coffee managed to go from a universally agreed-upon vice to at least a potential virtue in such a relatively short period of time? The Harvard researchers suspect that part of the issue is that coffee drinking has traditionally been associated with other high-health-risk habits--e.g. drinking more alcohol, smoking, and not exercising--that muddied the waters of what role the coffee itself was playing.
"The difficulty of being able to separate the effects of coffee on health from the effects of associated behaviors, such as smoking or alcohol use, is one reason that coffee was seen as negative for so long," said Kathryn Wilson, one of the Harvard researchers. "Until there were computers that could handle the necessary statistics, along with studies with larger sample sizes, it was very difficult to control for multiple factors at once to see their individual effects on health outcomes."
The caveats are important, too. As an article in the New York Times Sunday Business section this week pointed out, scientific studies do support Quaker's claim that eating oatmeal can reduce cholesterol ... but only if you eat three or more bowls of it a day. Same with Activa's claims that the probiotics in its yogurt help to stimulate digestion (at least three servings a day). A "healthy" diet trying to hew to the standards of all these studies would be a horrific gorge-feast of multiple pots of coffee and so much oatmeal, yogurt, and other supposedly "healthy" foods that there'd likely be nothing all that healthy, and certainly nothing balanced, about it.
And that's not even taking into account the changing views on what foods are even healthy. Eggs were bad, and then good. The big benefits of soy milk are now suspect, even as coffee is seeing a reprieve. Drinking alcohol is a health risk, but drinking a moderate amount of red wine is good for your heart. On the other hand, a 2002 study by Spanish researchers found that people who drank more than two glasses of wine a day had a dramatically reduced risk of getting a cold. The head could spin, trying to keep up with it all.
Given all of that, I asked the Harvard team what advice they had for the average person, based on their research results.
"I wouldn't recommend that men change their coffee consumption based on this study (or any single study)," Wilson answered. "[But] I think this study is part of mounting evidence that you don't need to feel guilty about your current coffee consumption."
Guiltless coffee. Is it possible? I might have to ponder that over a glass of red wine ... or another cup of steaming Java.
President-elect Donald Trump has committed a sharp breach of protocol—one that underscores just how weird some important protocols are.
Updated on December 2 at 7:49 p.m.
It’s hardly remembered now, having been overshadowed a few months later on September 11, but the George W. Bush administration’s first foreign-policy crisis came in the South China Sea. On April 1, 2001, a U.S. Navy surveillance plane collided with a Chinese jet near Hainan Island. The pilot of the Chinese jet was killed, and the American plane was forced to land and its crew was held hostage for 11 days, until a diplomatic agreement was worked out. Sino-American relations remained tense for some time.
Unlike Bush, Donald Trump didn’t need to wait to be inaugurated to set off a crisis in the relationship. He managed that on Friday, with a phone call to the president of Taiwan, Tsai Ing-wen. It’s a sharp breach with protocol, but it’s also just the sort that underscores how weird and incomprehensible some important protocols are.
A professor of cognitive science argues that the world is nothing like the one we experience through our senses.
As we go about our daily lives, we tend to assume that our perceptions—sights, sounds, textures, tastes—are an accurate portrayal of the real world. Sure, when we stop and think about it—or when we find ourselves fooled by a perceptual illusion—we realize with a jolt that what we perceive is never the world directly, but rather our brain’s best guess at what that world is like, a kind of internal simulation of an external reality. Still, we bank on the fact that our simulation is a reasonably decent one. If it wasn’t, wouldn’t evolution have weeded us out by now? The true reality might be forever beyond our reach, but surely our senses give us at least an inkling of what it’s really like.
A single dose of magic mushrooms can make people with severe anxiety and depression better for months, according to a landmark pair of new studies.
The doom hung like an anvil over her head. In 2012, a few years after Carol Vincent was diagnosed with non-Hodgkin lymphoma, she was waiting to see whether her cancer would progress enough to require chemotherapy or radiation. The disease had already done a number on her, inflating lymph nodes on her chin, collar bones, and groin. She battled her symptoms while running her own marketing business. To top it all off, she was going through menopause.
“Life is just pointless stress, and then you die,” she thought. “All I’m doing is sitting here waiting for all this shit to happen.”
When one day at an intersection she mulled whether it would be so bad to get hit by a car, she realized her mental health was almost as depleted as her physical state.
For nearly three decades, Fidel Castro devoted vast amounts of Cuba’s limited resources to the project of exporting his revolution to Africa, even as it stuttered at home. As leader of Cuba, Castro advocated a radical departure from the prevailing post-war liberal internationalism, premised more on the ideas of Frantz Fanon than those of Adam Smith. Decolonization seemed to offer a prime laboratory for that vision. Cuba volunteered doctors, nurses, military advisers, and troops to support what Castro and Che Guevara saw as progressive regimes—“sister countr[ies],” in Havana’s terminology—in Algeria, Eastern Congo-Kinshasa (today’s Democratic Republic of Congo), Congo-Brazzaville, Guinea-Bissau, and, later, Ethiopia.
A few weeks ago, I was trying to call Cuba. I got an error message—which, okay, international telephone codes are long and my fingers are clumsy—but the phone oddly started dialing again before I could hang up. A voice answered. It had a British accent and it was reading: “...the moon was shining brightly. The Martians had taken away the excavating-machine…”
Apparently, I had somehow called into an audiobook of The War of the Worlds. Suspicious of my clumsy fingers, I double-checked the number. It was correct (weird), but I tried the number again, figuring that at worst, I’d learn what happened after the Martians took away the excavating machine. This time, I got the initial error message and the call disconnected. No Martians.
This week, the U.S. president-elect spoke with the Pakistani prime minister and, according to the Pakistani government’s account of the conversation, delivered the following message: Everything is awesome. It was, arguably, the most surprising presidential phone call since George H.W. Bush got pranked by that pretend Iranian president.
Pakistan, Donald Trump reportedly told Nawaz Sharif, is a “fantastic” country full of “fantastic” people that he “would love” to visit as president. Sharif was described as “terrific.” Pakistanis “are one of the most intelligent people,” Trump allegedly added. “I am ready and willing to play any role that you want me to play to address and find solutions to the outstanding problems.”
The Daily Show host was measured, respectful, and challenging in his 26-minute conversation with TheBlaze pundit Tomi Lahren.
Tomi Lahren, the 24-year-old host of Tomi on the conservative cable network TheBlaze, feels like a pundit created by a computer algorithm, someone who primarily exists to say something provocative enough to jump to the top of a Facebook feed. She’s called the Black Lives Matter movement “the new KKK,” partly blamed the 2015 Chattanooga shootings on President Obama’s “Muslim sensitivity,” and declared Colin Kaepernick a “whiny, indulgent, attention-seeking cry-baby.” At a time when such charged political rhetoric feels increasingly like the norm, Lahren stands at one end of a widening gulf—which made her appearance on The Daily Show with Trevor Noah Wednesday night all the more fascinating.
In his first year at The Daily Show, Noah has struggled to distinguish himself in an outrage-driven late-night universe. He has sometimes seemed too flip about the failures of the country’s news media, something his predecessor Jon Stewart made a perennial target. Noah’s 26-minute conversation with Lahren, though, posted in its entirety online, set the kind of tone that Stewart frequently called for throughout his tenure. The segment never turned into a screaming match, but it also avoided platitudes and small-talk. Lahren was unapologetic about her online bombast and leaned into arguments that drew gasps and boos from Noah’s audience, but the host remained steadfastly evenhanded throughout. If Noah was looking for a specific episodethat would help him break out in his crowded field, he may have finally found it.
“A typical person is more than five times as likely to die in an extinction event as in a car crash,” says a new report.
Editor’s note: An earlier version of this story presented an economic modeling assumption—the .01 chance of human extinction per year—as a vetted scholarly estimate. Following a correction from the Global Priorities Project, the text below has been updated.
Nuclear war. Climate change. Pandemics that kill tens of millions.
These are the most viable threats to globally organized civilization. They’re the stuff of nightmares and blockbusters—but unlike sea monsters or zombie viruses, they’re real, part of the calculus that political leaders consider everyday. A new report from the U.K.-based Global Challenges Foundation urges us to take them seriously.
The nonprofit began its annual report on “global catastrophic risk” with a startling provocation: If figures often used to compute human extinction risk are correct, the average American is more than five times likelier to die during a human-extinction event than in a car crash.
"Dave, stop. Stop, will you? Stop, Dave. Will you stop, Dave?” So the supercomputer HAL pleads with the implacable astronaut Dave Bowman
in a famous and weirdly poignant scene toward the end of Stanley Kubrick’s
2001: A Space Odyssey. Bowman, having nearly been sent to a deep-space death by the malfunctioning machine, is calmly, coldly disconnecting the memory circuits that control its artificial “ brain. “Dave, my mind is going,” HAL says, forlornly. “I can feel it. I can feel it.”
I can feel it, too. Over the past few years I’ve had an uncomfortable sense that someone, or something, has been tinkering with my brain, remapping the neural circuitry, reprogramming the memory. My mind isn’t going—so far as I can tell—but it’s changing. I’m not thinking the way I used to think. I can feel it most strongly when I’m reading. Immersing myself in a book or a lengthy article used to be easy. My mind would get caught up in the narrative or the turns of the argument, and I’d spend hours strolling through long stretches of prose. That’s rarely the case anymore. Now my concentration often starts to drift after two or three pages. I get fidgety, lose the thread, begin looking for something else to do. I feel as if I’m always dragging my wayward brain back to the text. The deep reading that used to come naturally has become a struggle.
Critics say she failed to energize the Democratic base. But vote totals show her biggest shortcomings were in counties that opposed Barack Obama the most.
It now seems likely that Hillary Clinton will get fewer votes than Barack Obama did in 2012. More distressingly for Democrats, she fared worse in Democratic-leaning cities that anchor swing states, including Detroit, Cleveland, and Milwaukee. To critics on the left, that’s evidence of a campaign that dragged its feet, and a candidate who took her base for granted. Her defeat, in their minds, was an unforced error.
But the numbers show something different. There’s no question Clinton faltered in some Democratic cities, but the gaps between her haul and Obama’s in those locations were modest. The vast majority of her deficit came instead from counties that Obama lost in 2012: They didn’t like him, but they really hated her.
