It is more than just dark-colored liquid with caffeine. Coffee actually contains hundreds of different compounds, some of which have important health benefits.

Several massive studies have now shown that the people who drink the most coffee live longer and have a reduced risk of diseases like Alzheimer's and diabetes.

Coffee Is a Major Source of Antioxidants

When hot water runs through the coffee grounds while brewing, the substances in the coffee beans mix with the water and become part of the drink. Some of these substances are well known, including caffeine, but there are hundreds of other compounds in there as well, many of which science has yet to identify.

Many of these compounds are antioxidants that protect our bodies from oxidation, which involves free radicals that damage molecules in the body. Without getting into complicated details, oxidation is believed to be one of the mechanisms behind aging and common diseases like cancer and heart disease.

Coffee, believe it or not, happens to be the biggest source of antioxidants in the Western diet, outranking both fruits and vegetables, combined.

When you're treating yourself to a cup of coffee, you're not only getting caffeine but a whole bunch of other beneficial compounds, including powerful antioxidants.

Several Massive Studies Show That People Who Drink Coffee Live Longer Than Those Who Don't

There are several studies showing that when people drink coffee, they have a lower risk of dying from a range of serious diseases.

A groundbreaking study, the largest of its kind, was published in the New England Journal of Medicine in 2012: Freedman ND, et al. Association of coffee drinking with total and cause-specific mortality. New England Journal of Medicine, 2012. In this study, 402,260 individuals between 50 and 71 years of age were asked about their coffee consumption.

The results were fairly remarkable. After following the people for 12-13 years, those who drank the most coffee were significantly less likely to have died. As you can see from the graph, the more coffee people drank, the lower their risk of death was.

The sweet spot seems to be at 4-5 cups per day, where men had a 12 percent reduced risk and women a 16 percent reduced risk. Drinking six or more cups per day provided no additional benefit.

However, even moderate consumption of coffee (one cup per day) was associated with a 5-6 percent reduction in risk of death, showing that even a little bit is enough to have an effect.

Although these numbers may seem small, given how incredibly widespread coffee consumption really is, this could have implications for millions of people.

When they looked at particular causes of death, they found that the coffee drinkers were less likely to die from infections, injuries and accidents, respiratory disease, diabetes, stroke and heart disease. The benefit does not appear to be attributable to the caffeine, because both decaf and regular coffee had the same effect.

Of course, this is a so-called observational study, which can not prove that coffee caused the reduction in risk. But it is a good reassurance that coffee is, at the very least, NOT the villain it has been made out to be.

Many Other Studies Have Lead to Similar Results

The effects of coffee on health have actually been studied very thoroughly in the past few decades. At least two other studies have shown that coffee drinkers have a lower risk of premature death.

If we look at specific diseases, coffee drinkers have a much lower risk of Alzheimer's, Parkinson's, type 2 diabetes and liver diseases, to name a few.

There are also studies from Harvard showing that coffee may make you happier, reducing the risk of depression by by 20 percent and the risk of suicide by 53 percent.

So, not only does coffee add years to your life, but it may also add life to your years.

One million species are at risk of extinction from human activity, warns a recent study by scientists with the United Nations. We need to cut greenhouse gas pollution across all sectors to avoid catastrophic climate change — and we need to do it fast, said the Intergovernmental Panel on Climate Change.

This research should serve as a rallying cry for polluting industries to make major changes now. Yet the agriculture industry continues to lag behind.

Botswana, home to one third of Africa's elephants, announced Wednesday that it was lifting its ban on the hunting of the large mammals.

"The Ministry of Environment, Natural Resources Conservation and Tourism wishes to inform the public that following extensive consultations with all stakeholders, the Government of Botswana has taken a decision to lift the hunting suspension," the government announced in a press release shared on social media.

Readers of this blog know how concerned EDF is over the Trump EPA's approval of many dozens of new chemicals based on its mere "expectation" that workers across supply chains will always employ personal protective equipment (PPE) just because it is recommended in the manufacturer's non-binding safety data sheet (SDS).

In a big victory for animals, Prada has announced that it's ending its use of fur! It joins Coach, Jean Paul Gaultier, Giorgio Armani, Versace, Ralph Lauren, Vivienne Westwood, Michael Kors, Donna Karan and many others PETA has pushed toward a ban.

This is a victory more than a decade in the making. PETA and our international affiliates have crashed Prada's catwalks with anti-fur signs, held eye-catching demonstrations all around the world, and sent the company loads of information about the fur industry. In 2018, actor and animal rights advocate Pamela Anderson sent a letter on PETA's behalf urging Miuccia Prada to commit to leaving fur out of all future collections, and the iconic designer has finally listened.

If people in three European countries want to fight the climate crisis, they need to chill out more.

That's the conclusion of a new study from think tank Autonomy, which found that Germany, the UK and Sweden all needed to drastically reduce their workweeks to fight climate change.

"The rapid pace of labour-saving technology brings into focus the possibility of a shorter working week for all, if deployed properly," Autonomy Director Will Stronge said, The Guardian reported. "However, while automation shows that less work is technically possible, the urgent pressures on the environment and on our available carbon budget show that reducing the working week is in fact necessary."

The report found that if the economies of Germany, Sweden and the UK maintain their current levels of carbon intensity and productivity, they would need to switch to a six, 12 and nine hour work week respectively if they wanted keep the rise in global temperatures to the below two degrees Celsius promised by the Paris agreement, The Independent reported.

The study based its conclusions on data from the UN and the OECD (Organisation for Economic Co-operation and Development) on greenhouse gas emissions per industry in all three countries.

The report comes as the group Momentum called on the UK's Labour Party to endorse a four-day work week.

"We welcome this attempt by Autonomy to grapple with the very real changes society will need to make in order to live within the limits of the planet," Emma Williams of the Four Day Week campaign said in a statement reported by The Independent. "In addition to improved well-being, enhanced gender equality and increased productivity, addressing climate change is another compelling reason we should all be working less."

Supporters of the idea linked it to calls in the U.S. and Europe for a Green New Deal that would decarbonize the economy while promoting equality and well-being.

"This new paper from Autonomy is a thought experiment that should give policymakers, activists and campaigners more ballast to make the case that a Green New Deal is absolutely necessary," Common Wealth think tank Director Mat Lawrence told The Independent. "The link between working time and GHG (greenhouse gas) emissions has been proved by a number of studies. Using OECD data and relating it to our carbon budget, Autonomy have taken the step to show what that link means in terms of our working weeks."

Stronge also linked his report to calls for a Green New Deal.

"Becoming a green, sustainable society will require a number of strategies – a shorter working week being just one of them," he said, according to The Guardian. "This paper and the other nascent research in the field should give us plenty of food for thought when we consider how urgent a Green New Deal is and what it should look like."
