Coffee and Antioxidants: Everything You Need to Know
Still, when you look at the evidence, most studies on coffee and health find that it's beneficial.
Many of coffee's positive health effects may be due to its impressive content of powerful antioxidants.
In fact, studies show that coffee is one of the largest sources of antioxidants in the human diet.
This article tells you everything you need to know about coffee's impressive antioxidant content.
Loaded With Several Powerful Antioxidants
Your body is under constant attack from so-called free radicals, which can damage important molecules like proteins and DNA.
Antioxidants can effectively disarm free radicals, thus protecting against aging and many diseases that are partly caused by oxidative stress, including cancer.
Hydrocinnamic acids are very effective at neutralizing free radicals and preventing oxidative stress (8).
Coffee is very rich in antioxidants—including polyphenols and hydrocinnamic acids—that may improve health and reduce your risk of several diseases.
The Biggest Dietary Source of Antioxidants
Beverages are a much larger source of antioxidants in the Western diet than food. In fact, 79% of dietary antioxidants come from beverages, while only 21% come from food (16).
That's because people tend to consume more servings of antioxidant-rich drinks than foods.
In one study, researchers looked at the antioxidant content of different foods by serving size.
Coffee ranked 11th on the list behind several types of berries (7).
Yet, as many people eat few berries but drink several cups of coffee per day, the total amount of antioxidants provided by coffee far outweighs that of 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% of people's total antioxidant intake.
People tend to get more antioxidants from beverages than foods, and studies from all over the world demonstrate that coffee is the single biggest dietary source of antioxidants.
Linked to a Reduced Risk of Many Diseases
Coffee is associated with a reduced risk of many diseases.
Still, 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.
Drinking coffee has been linked to numerous health benefits, including a reduced risk of type 2 diabetes and liver, heart, and neurological diseases. It may also benefit mental health and help you live longer.
The Bottom Line
There are many types of dietary antioxidants, and coffee is a very good source of some of them.
However, it does not provide the same antioxidants as whole plant foods like fruits and vegetables — so while coffee may be the biggest dietary source of antioxidants, it should never be your only source.
For optimal health, it's best to get a variety of vitamins, minerals, antioxidants, and plant compounds from many different sources.

Can't stop eating that bag of chips until you're licking the salt nestled in the corners of the empty package from your fingers? You're not alone. And it's not entirely your fault that the intended final handful of chips was not, indeed, your last for that snacking session. Many common snack foods have been expertly engineered to keep us addicted, almost constantly craving more of whatever falsely satisfying manufactured treat is in front of us.

A new paper just out in The Lancet Planetary Health provides the first global indication that recent temperature increases, propelled by climate change, are in fact contributing significantly to longer and more intense pollen seasons.

In propping up the coal industry, the Trump administration is not only contributing to dangerous pollution, fossil fuel emissions and the climate crisis, it is also now clinging to a far more expensive energy production model than renewable energy offers.
That's according to a new report from renewable energy analysis firm Energy Innovation, showing that about three-quarters of power produced by the nation's remaining coal plants is more expensive for American households than renewables including wind, solar and hydro power.
At least 19 people have died and more than 100 have been injured in flash flooding in the south of Iran, the country's semi-official Tasnim News Agency said. The city of Shiraz in Fars province was the worst hit by the flooding, which occurred after a month's worth of rain fell in a few hours, CNN meteorologist Taylor Ward said.
Climate change is having a grizzly effect on Mount Everest as melting snow and glaciers reveal some of the bodies of climbers who died trying to scale the world's highest peak.
The Navajo Nation has decided to stop pursuing the acquisition of a beleaguered coal-fired power plant in Arizona, locking in the plant to be taken offline and its associated coal mine to close later this year.
A Navajo Nation Council committee voted 11-9 last week to stop pursuing the purchase of the 2,250-megawatt Navajo Generating Station, which with the Kayenta coal mine provides more than 800 jobs to primarily Navajo and Hopi workers as well as tribal royalties.
A coalition of utilities that own the plant said in 2017 it would cease operations due to increased economic pressure, and the plant's future has proved a flash point for national and regional energy policy and raised larger questions on how Native communities will handle ties to fossil fuel industries as the economy changes.
