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.

- Exposure to phthalates was associated with autism traits in boys (but not girls) between ages 3 and 4 years, according to a new study.
- However, the risk was diminished in women who took folic acid during their pregnancy.
- This study is the first to find that folic acid supplements provide a protective effect from phthalates.
Exposure in the womb to a group of endocrine-disrupting chemicals called phthalates was associated with autism traits in boys (but not girls) between ages 3 and 4 years, according to a new study.
