Coffee is one of the most sought-after commodities, and it's part of every morning and lunch break for people all over the world owing to the caffeine in it.
Now, there's a new reason for people to continue reaching for their coffee mugs -- it's been discovered that coffee also contains chlorogenic acid, which has various health benefits.
Mostly found in coffee beans and fruits, chlorogenic acid is phytochemical that helps reduce blood sugar levels.
Numerous studies show it has anti-oxidant properties and is also proven to have anti-cancer effects.
Studies are still underway, so the amount of chlorogenic acid in coffee isn't known for sure.
According to local researchers, the amount appears to depend on how it's roasted, ground and brewed..
Researchers from Gyeonggi Institute of Health Environment say some methods can even quadruple the amount of chlorogenic acid.
To get the most chlorogenic acid in a cup of coffee, it starts with the roast.
Beans should be roasted to medium, because at that level they've been shown to have more than twice the amount of chlorogenic acid as medium-dark roasted beans.
The beans should also be ground more finely, which can boost chlorogenic acid levels by up to 86 percent.
And there's a specific rule for brewing the coffee.
If you were making a single cup, water should be dripped through the grounds three separate times to get the most chlorogenic acid out of them.
The researchers did caution that, despite its health benefits, too much chlorogenic can have negative effects for people with certain conditions.
"Chlorogenic acid is acid, after all. So it can cause some minor damage to someone with an irritated stomach or esophagus. What we recommend is three cups of coffee per day."
