For years, doctors warned that coffee was bad for your heart.
They didn’t have much evidence to support this advice other than the fact that caffeine slightly raises your blood pressure.
But recent studies show that effect is only temporary. And it’s harmless in just about everybody.
Nutritional researchers have come to view coffee as a true superfood. Studies show it helps with weight loss, prevents diabetes, reduces artery calcification that leads to heart attacks, lowers Alzheimer’s risk, and improves cognition and mood.
The wide-ranging health benefits come from the high levels of antioxidants and anti-inflammatory compounds in coffee. These substances act as a health shield for cells throughout your body.
Coffee: Which Type has the Most Health Perks?
Go into any Starbucks and you’ll have many types of coffee to choose from. Is one kind healthier than others?
One study provides an answer…at least when it comes to dark vs. light roasts.
It’s the first research to test different roasting methods on a cellular level.
Scientists from several universities in Korea teamed up to examine the effects of roasting on coffee’s antioxidant and anti-inflammatory properties.
They tested light, medium, city (sometimes called “continental” or “light French roast”), and French (dark) roast. For comparison, regular Folgers and most other major store brands are medium-roast coffees.
A coffee solution of each type of roast was introduced to mice cells.
Then scientists observed its antioxidant and anti-inflammatory effects on the cells.
Light roast coffee had the most benefit, beating out medium roast by a few percentage points. City roast was about 10% less beneficial. And French roast dropped a substantial 25%.
The article was published in the Journal of Medicinal Food.
Dr. Sampath Parthasarathy is associate dean of the University of Central Florida College of Medicine. He is editor of the journal that published the study.
“Coffee drinkers are passionate about different roasts—light, medium, and dark,” he said. “This study suggests that some of the potentially beneficial compounds could be affected by the roasting process. This article would certainly change my coffee roast preference.”
Dark Roasting Wrecks One Big Coffee Benefit
The researchers said longer roasting robs coffee of one important health-promoting compound. Coffee contains chlorogenic acid. It’s a phytochemical that triggers antioxidant activity, reduces inflammation, and controls blood sugar levels. 
About 12% of the dry weight of unroasted coffee is chlorogenic acid. But roasting destroys it. The darker the coffee bean, the less chlorogenic acid it has.
If you like dark coffee, this study doesn’t necessarily mean you should switch to a light roast. Making your coffee stronger or using high-extraction methods such as an espresso maker will increase the chlorogenic acid in your cup.
But whether light or dark, you should choose organic coffee whenever you can…and skip artificial creamers and sweeteners.
