Coffee: The World’s Biggest Source of Antioxidants
There are mixed opinions about coffee.

Some believe it is healthy and energizing, while others claim it is addictive and harmful.
The reason for this may be the impressive amount of powerful antioxidants found in coffee.
In fact, studies show that coffee provides more antioxidants in the diet than any food group.
Coffee is Loaded with Several Powerful Antioxidants
Our bodies are under constant attack by reactive molecules called “free radicals."
These molecules have unpaired electrons that can damage important cell structures like proteins and DNA.
This is where antioxidants step in. They donate electrons to the free radicals, effectively disarming them.
This is believed to be protective against aging and many diseases that are partly caused by oxidative stress, including cancer.
Additionally, antioxidants can have various other biological effects and are considered to be very important for overall health.
Hydrocinnamic acids are very effective at neutralizing free radicals and preventing oxidative stress (8).
Bottom line: Coffee contains very large amounts of antioxidants, including polyphenols and hydrocinnamic acids. These antioxidants may improve health and help reduce the risk of several diseases.
Dietary Sources of Antioxidants
Most people consume about 1–2 grams of antioxidants per day.
Beverages are actually a much larger source of antioxidants in the Western diet than food. In fact, 79 percent of dietary antioxidants come from beverages, while only 21 percent come from food (16).
Bottom line: Most antioxidants in the Western diet come from beverages such as coffee and tea. Only 21 percent of dietary antioxidants come from food.
Coffee is the Biggest Dietary Source of Antioxidants
In one study, researchers looked at the antioxidant content of different foods by serving size.
Coffee ranked 11th on the list, after several different types of berries (7).
However, very few people eat large amounts of berries, but drinking several cups of coffee per day is common.
For this reason, the total amount of antioxidants provided by coffee far outweighs the amounts in berries, even though berries may contain greater amounts per serving.
In Norwegian and Finnish studies, coffee was shown to be the single biggest antioxidant source, providing about 64 percent of the total antioxidant intake.
Coffee is Linked to a Reduced Risk of Many Diseases
Drinking coffee has been associated with a reduced risk of many diseases.
However, keep in mind that most of these studies are observational. They cannot prove that coffee caused the reduction in disease risk, only that coffee drinkers were less likely to get these diseases.
Are Coffee Antioxidants Equal to Those Found in Fruits and Vegetables?
There are many types of dietary antioxidants and coffee is a very good source of some of them.
However, it does not contain the same antioxidants as whole plant foods like fruits and vegetables.
For optimal health, it is best to get a variety of vitamins, minerals, antioxidants and plant compounds from many different sources.
So while coffee may be the biggest source of antioxidants in the diet, it should never be relied on as the only source of antioxidants.

Using one of the world's problems to solve another is the philosophy behind a Norwegian start-up's mission to develop affordable housing from 100% recycled plastic.

John Kerry helped bring the world into the Paris climate agreement and expanded America's reputation as a climate leader. That reputation is now in tatters, and President-elect Joe Biden is asking Kerry to rebuild it again – this time as U.S. climate envoy.
Energy Is at the Center of the Climate Challenge<p>The <a href="https://science2017.globalchange.gov/chapter/1/" target="_blank">effects of climate change</a> are already evident across the globe, from <a href="https://theconversation.com/100-degrees-in-siberia-5-ways-the-extreme-arctic-heat-wave-follows-a-disturbing-pattern-141442" target="_blank">extreme heat waves</a> to <a href="https://science2017.globalchange.gov/chapter/12/" target="_blank">sea level rise</a>. But while the challenge is daunting, there is hope. Solar and wind power have become the <a href="https://www.irena.org/publications/2020/Jun/Renewable-Power-Costs-in-2019" target="_blank">cheapest forms of power generation globally</a>, and technology progress and innovation continue apace to support a transition to clean energy.</p><p>In the U.S. under a Biden administration, long-term national climate legislation will depend on who controls the Senate, and that won't be clear until after two run-off elections in Georgia in January.</p><p>But there is no shortage of <a href="https://www.bloomberg.com/features/2020-biden-climate-change-advice/" target="_blank">ideas for ways Biden</a> could still take action even if his proposals are blocked in Congress. For example, he could use executive orders and direct government agencies to tighten regulations on greenhouse gas emissions; increase research and development in clean energy technologies; and empower states to exceed national standards, <a href="https://www.reuters.com/article/us-autos-emissions-california/defying-trump-california-locks-in-vehicle-emission-deals-with-major-automakers-idUSKCN25D2CH" target="_blank" rel="noopener noreferrer">as California did in the past with auto emission standards</a>. A focus on a just and equitable transition for communities and people affected by the decline of fossil fuels will also be key to creating a sustainable transition.</p><p>The U.S. position as the world's largest oil and gas producer and consumer creates political challenges for any administration. U.S. forays into European energy security are often treated with suspicion. Recently, France blocked <a href="https://www.wsj.com/articles/frances-engie-backs-out-of-u-s-lng-deal-11604435609" target="_blank">a multi-billion dollar contract</a> to buy U.S. liquefied natural gas because of concerns about limited emissions regulations in Texas.</p><p>Strengthening cooperation and partnerships with like-minded countries will be critical to bring about a transition to cleaner energy as well as sustainability in agriculture, forestry, water and other sectors of the global economy.</p>
Creating a Global Sustainable Transition<p>How the world recovers from COVID-19's economic damage could help drive a lasting shift in the global energy mix.</p><p>Nearly one-third of Europe's US$2 trillion economic relief package <a href="https://www.bloomberg.com/news/articles/2020-07-21/eu-approves-biggest-green-stimulus-in-history-with-572-billion-plan" target="_blank" rel="noopener noreferrer">involves investments that are also good for the climate</a>. The European Union is also strengthening its 2030 climate targets, though each country's energy and climate plans will be critical for successfully implementing them. The <a href="https://joebiden.com/clean-energy/" target="_blank" rel="noopener noreferrer">Biden plan</a> – including a $2 trillion commitment to developing sustainable energy and infrastructure – is aligned with a global energy transition, but its implementation is also uncertain.</p><p>Once Biden takes office, Kerry will be joining ongoing <a href="https://www.un.org/en/conferences/energy2021/about#:%7E:text=The%20overarching%20goal%20of%20the,2030%20Agenda%20for%20Sustainable%20Development.&text=Accelerate%20delivery%20of%20United%20Nations,related%20issues%20at%20all%20levels." target="_blank" rel="noopener noreferrer">high-level discussions on the energy transition</a> at the U.N. General Assembly and other gatherings of international leaders. With the U.S. no longer obstructing work on climate issues, the G-7 and G-20 have more potential for progress on energy and climate.</p><p>Lots of technical details still need to be worked out, including international trade frameworks and standards that can help countries lower greenhouse gas emissions enough to keep global warming in check. <a href="https://www.carbonpricingleadership.org/what" target="_blank" rel="noopener noreferrer">Carbon pricing</a> and <a href="https://www.csis.org/analysis/how-can-europe-get-carbon-border-adjustment-right" target="_blank" rel="noopener noreferrer">carbon border adjustment taxes</a>, which create incentive for companies to reduce emissions, may be part of it. A consistent and comprehensive set of national energy transition plans will also be needed.</p><p>The global shift to <a href="https://www.irena.org/publications/2019/Jan/A-New-World-The-Geopolitics-of-the-Energy-Transformation" target="_blank">clean energy will also have geopolitical implications for countries and regions</a>, and this will have a profound impact on wider international relations. Kerry, with his experience as secretary of state in the Obama administration, and Biden's plan to make the climate envoy position part of the National Security Council, may help mend these relations. In doing so, the U.S. may again join the wider community of countries willing to lead.</p>
