Coffee Polyphenols May Help You Sleep - And Burn Fat While They Do

Most people drink coffee to wake up — but did you know that coffee contains polyphenols that may help you sleep? A recent study suggests that chlorogenic acids, the most common polyphenols in coffee, may help people fall asleep as well as increase fat burning during sleep. And to clarify, this coffee extract doesn’t contain caffeine the way a cup of coffee does.


Participants in the study included nine healthy people who were given a drink containing either 600 mg of chlorogenic acids or a placebo for five days. The chlorogenic acid drink contained 68% caffeoylquinic acids, 14% feruloylguinic acids, and 19% dicaffeoylguinic acids. The researchers assessed participants’ sleep inside a metabolic chamber on the last day.


The sleep assessment found that participants fell asleep an average of nine minutes after drinking the supplement drink — which contained  compared with 16 minutes after consuming the placebo drink. The supplement group also had an average 50% increase in the breakdown of stored fat, when compared with the placebo group.


Researchers from the University of Tsukuba and Kao Corporation conducted the study. It was published online ahead of print on April 17, 2017, in the British Journal of Nutrition.


The health benefits associated with coffee are generally attributed to its polyphenol content. Previous studies have linked polyphenol intake with a variety of health benefits, including helping with weight management, fighting certain cancers, and reducing inflammation. Polyphenols can be found naturally in many foods, including honey, a variety of fruits and vegetables, red wine, chocolate, tea, certain oils and many types of grain.
