Coffee is such a staple in the American diet. From their a.m. wake-up call to their cup of decaf with dessert after dinner, Americans are drinking the stuff all day long. And while this miracle brew has been besmirched with old wives' tales that it'll stunt your growth (false, by the way), coffee, in truth, is brimming over with health benefits.
Why the discrepancy? Dave Asprey, author of The Bulletproof Diet, explains that for coffee to be good for you, it has to be good coffee. "The studies on coffee and health go back and forth," he explains. "Some studies show health benefits, while others show negative impacts. This might seem confusing, but the reason is simple: Bad coffee is bad for you, and scientists don't differentiate between types of coffee when they run these studies."
Asprey points out that coffee can be a major source of mold toxins, which come with their own set of negative health consequences. But some coffees are moldier than others. For instance, beans are cleaner than instant coffee. Fortunately, if you pick a good clean bean, you can enjoy these nine benefits of a healthy cup of joe.
1. Increased Longevity
It doesn't get much simpler than this: Coffee reduces your chance of dying. According to research published in The American Journal of Epidemiology, four cups of coffee per day reduced the risk of death, from any cause, by 16 percent, and three cups per day reduced risk of death from cardiovascular disease by 21 percent.
2. Protection Against Cancer
Research conducted at the Fred Hutchinson Cancer Research Center that found that drinking four or more cups of coffee per day reduced a man's risk of prostate cancer recurrence by 59 percent. One explanation for this finding is that coffee is loaded with antioxidants. "The richest source of polyphenols in Western diets by far is coffee," says Asprey. And previous research has shown that polyphenols can reduce the risk of the onset of prostate cancer.
It's not just cancer of the prostate, either. A meta-analysis performed by Chinese researchers found that higher coffee consumption could reduce the risk of liver cancer by 50 percent, and another study by Canadian researchers found that high coffee intake was associated with reduced risk of breast cancer.
3. More Weight Loss
Coffee may be your new favorite diet food. First, Asprey points out, the polyphenols in coffee are a prebiotic for the good bacteria in your gut, a species called Bacteroidetes. This species of gut bacteria has been associated with thinness. "You can't increase the population of that species with probiotic capsules," he explains; "you have to feed it." Plus, the caffeine makes it thermogenic, meaning it helps you increase your resting metabolic rate and energy expenditure, leading to more calories burned.
4. Less Inflammation (And Maybe Alzheimer's Prevention)
Coffee may help keep brain inflammation low, according to research from the University of Illinois. "We have discovered a novel signal that activates the brain-based inflammation associated with neurodegenerative diseases, and caffeine appears to block its activity," said Gregory Freund, MD, professor and head of the pathology department at University of Illinois. Reducing your brain inflammation is proving to be a critical way to prevent age-related cognitive decline and neurodegenerative diseases, which may explain why in previous studies coffee seemed to protect against Alzheimer's disease.
5. Headache Prevention
While it's true that caffeine withdrawal may contribute to headaches if you overdo it on the java, drinking coffee regularly (though moderately) can reduce your risk of chronic headaches, found researchers in Norway. They found that those who drank 241 to 400 milligrams of caffeine (equivalent to two to three cups of coffee) regularly had the least number of headaches. Those who drank the least coffee (less than 240 milligrams of caffeine) had the highest instances of chronic headaches (more than 14 days per month with a headache).
6. A Mood Boost
"The caffeine in coffee binds to receptors for neurotransmitters associated with your mood," Asprey says. This may explain why coffee doesn't just give you a burst of energy, it may also brighten your day. According to a study from The Archives of Internal Medicine, women who drank at least four cups of coffee daily were 20 percent less like to become depressed.
7. Lower Diabetes Risk
Harvard researchers found that drinking an extra cup a day for four years decreased the risk of diabetes for coffee drinkers in their study by 11 percent compared to those who didn't change their coffee drinking habits. Surprisingly, the inverse was also true: Decreasing coffee consumption increased people's risk by 17 percent. They do point out, however, that the coffee was served black or with just a little milk and sugar. Making that a sugar-jacked cup of java is not a good way to stave off diabetes.
"Caffeine also increases insulin sensitivity in healthy humans, which is extremely important to sustained weight loss," Asprey adds.
8. A Liver Cleanup
Coffee isn't usually thought of as a detox drink, but research has found that not only does coffee lower abnormal liver enzyme levels, but it can even reduce your risk for cirrhosis, a liver disease. Drinking two or more cups of coffee per day reduces your risk of death by cirrhosis by 66 percent, according to research published in Hepatology. Interestingly, tea, fruit juice, and soda consumption don't affect cirrhosis mortality; only coffee does.
9. Heart Protection
Every body part wants to get in on the benefits of coffee, and the heart is no exception. A meta-analysis published by the American Heart Association's journal,Circulation, found that those who drank three to five cups per day had the lowest risk for cardiovascular disease.
In fact, a separate analysis published in The Central European Journal of Medicinefound that light coffee consumption reduced the risk of stroke by 10 percent; moderate consumption, by 14 percent; and heavy consumption, by 17 percent in men.

The speed and scale of the response to COVID-19 by governments, businesses and individuals seems to provide hope that we can react to the climate change crisis in a similarly decisive manner - but history tells us that humans do not react to slow-moving and distant threats.
A Game of Jenga<p>Think of it as a game of Jenga and the planet's climate system as the tower. For generations, we have been slowly removing blocks. But at some point, we will remove a pivotal block, such as the collapse of one of the major global ocean circulation systems, for example the Atlantic Meridional Overturning Circulation (AMOC), that will cause all or part of the global climate system to fall into a planetary emergency.</p><p>But worse still, it could cause runaway damage: Where the tipping points form a domino-like cascade, where breaching one triggers breaches of others, creating an unstoppable shift to a radically and swiftly changing climate.</p><p>One of the most concerning tipping points is mass methane release. Methane can be found in deep freeze storage within permafrost and at the bottom of the deepest oceans in the form of methane hydrates. But rising sea and air temperatures are beginning to thaw these stores of methane.</p><p>This would release a powerful greenhouse gas into the atmosphere, 30-times more potent than carbon dioxide as a global warming agent. This would drastically increase temperatures and rush us towards the breach of other tipping points.</p><p>This could include the acceleration of ice thaw on all three of the globe's large, land-based ice sheets – Greenland, West Antarctica and the Wilkes Basin in East Antarctica. The potential collapse of the West Antarctic ice sheet is seen as a key tipping point, as its loss could eventually <a href="https://science.sciencemag.org/content/324/5929/901" target="_blank">raise global sea levels by 3.3 meters</a> with important regional variations.</p><p>More than that, we would be on the irreversible path to full land-ice melt, causing sea levels to rise by up to 30 meters, roughly at the rate of two meters per century, or maybe faster. Just look at the raised beaches around the world, at the last high stand of global sea level, at the end of the Pleistocene period around 120,0000 years ago, to see the evidence of such a warm world, which was just 2°C warmer than the present day.</p>
Cutting Off Circulation<p>As well as devastating low-lying and coastal areas around the world, melting polar ice could set off another tipping point: a disablement to the AMOC.</p><p>This circulation system drives a northward flow of warm, salty water on the upper layers of the ocean from the tropics to the northeast Atlantic region, and a southward flow of cold water deep in the ocean.</p><p>The ocean conveyor belt has a major effect on the climate, seasonal cycles and temperature in western and northern Europe. It means the region is warmer than other areas of similar latitude.</p><p>But melting ice from the Greenland ice sheet could threaten the AMOC system. It would dilute the salty sea water in the north Atlantic, making the water lighter and less able or unable to sink. This would slow the engine that drives this ocean circulation.</p><p><a href="https://www.carbonbrief.org/atlantic-conveyor-belt-has-slowed-15-per-cent-since-mid-twentieth-century" target="_blank">Recent research</a> suggests the AMOC has already weakened by around 15% since the middle of the 20th century. If this continues, it could have a major impact on the climate of the northern hemisphere, but particularly Europe. It may even lead to the <a href="https://ore.exeter.ac.uk/repository/handle/10871/39731?show=full" target="_blank" rel="noopener noreferrer">cessation of arable farming</a> in the UK, for instance.</p><p>It may also reduce rainfall over the Amazon basin, impact the monsoon systems in Asia and, by bringing warm waters into the Southern Ocean, further destabilize ice in Antarctica and accelerate global sea level rise.</p>
The Atlantic Meridional Overturning Circulation has a major effect on the climate. Praetorius (2018)
Is it Time to Declare a Climate Emergency?<p>At what stage, and at what rise in global temperatures, will these tipping points be reached? No one is entirely sure. It may take centuries, millennia or it could be imminent.</p><p>But as COVID-19 taught us, we need to prepare for the expected. We were aware of the risk of a pandemic. We also knew that we were not sufficiently prepared. But we didn't act in a meaningful manner. Thankfully, we have been able to fast-track the production of vaccines to combat COVID-19. But there is no vaccine for climate change once we have passed these tipping points.</p><p><a href="https://www.weforum.org/reports/the-global-risks-report-2021" target="_blank">We need to act now on our climate</a>. Act like these tipping points are imminent. And stop thinking of climate change as a slow-moving, long-term threat that enables us to kick the problem down the road and let future generations deal with it. We must take immediate action to reduce global warming and fulfill our commitments to the <a href="https://www.ipcc.ch/sr15/" target="_blank" rel="noopener noreferrer">Paris Agreement</a>, and build resilience with these tipping points in mind.</p><p>We need to plan now to mitigate greenhouse gas emissions, but we also need to plan for the impacts, such as the ability to feed everyone on the planet, develop plans to manage flood risk, as well as manage the social and geopolitical impacts of human migrations that will be a consequence of fight or flight decisions.</p><p>Breaching these tipping points would be cataclysmic and potentially far more devastating than COVID-19. Some may not enjoy hearing these messages, or consider them to be in the realm of science fiction. But if it injects a sense of urgency to make us respond to climate change like we have done to the pandemic, then we must talk more about what has happened before and will happen again.</p><p>Otherwise we will continue playing Jenga with our planet. And ultimately, there will only be one loser – us.</p>
