Coffee is Loaded With Antioxidants

I always knew coffee had some antioxidants, but was unaware than it had more than tea. Antioxidants protect the body from free radicals. Dr. Jonny Bowden in his book The 150 Healthiest Foods on Earth lists Coffee as one of the top 150 foods. He even states it has antioxidant power greater than tea or cocoa.

…a study in the Journal of Agriculture and Food Chemistry in 2001 found that coffee has significantly more total antioxidant activity than either cocoa, green tea, black tea, or herbal tea.

What makes coffee such a rich source of antioxidants? According to Dr. Bowden, coffee has chlorogenic acid and caffeic acid. Both are strong antioxidants. The Coffee Science Information Center states that a 200 ml of arabica coffee (~6.7 ounces) can contain between 70 and 200 mg chlorogenic acid.

The Wikipedia has this to say about chlorogenic acid and caffeic acid:

Chlorogenic acid and caffeic acid are antioxidants in vitro and might therefore contribute to the prevention of Type 2 Diabetes Mellitus and cardiovascular disease. It is claimed to have antiviral, antibacterial and antifungal effects with relatively low toxicity and side effects, alongside properties that do not lead to antimicrobial resistance.

The Coffee Science Information Center also reports that the roasting time of coffee will impact the antioxidant levels.

The roasting of coffee beans dramatically increases their total antioxidant activity. A roasting time of 10 minutes (medium-dark roast) was found to produce coffee with optimal oxygen scavenging and chain breaking activities in vitro (6).


I think I’ll go have a mug of antioxidants.

Michael Allen Smith fell in love with coffee while attending college. Shortly after graduating college, he found himself in the Tampa Bay area far away from the good coffee he had at The Ohio State University. That is when he starting home roasting coffee. Less than a year later in April 1999, he launched the coffee website has been going strong ever since with hundreds of articles and tutorials submitted by over one hundred contributors.

In 2007, Michael moved to America's coffee capitol Seattle, Washington. He has visited close to three hundred different coffee places in Seattle, Portland,Vancouver and San Francisco and met many of the top roasters and baristas in the country. Since 2009, Michael has been the Organizer of the Coffee Club of Seattle, which is a Meetup group of over 800 coffee enthusiasts. Besides the social aspect of the group, the Coffee Club of Seattle partners with local coffee professionals for educational events such as coffee cuppings, brewing demonstrations and roasting tours.

Unrelated to coffee, Michael has a personal blog at which covers several topics including fitness, cooking and economics.
