Coffee Consumption Boosts Energy but Brewing Method Affects Cholesterol Levels

Black coffee, made without milk or sugar, contains low calories, caffeine, antioxidants and other plant compounds that can increase alertness, support metabolism and enhance physical performance. Studies cite benefits such as improved mental focus, temporary metabolic boost and rich antioxidant content.

Recent research shows that the way coffee is brewed influences its impact on cholesterol. Diterpenes—naturally occurring compounds in coffee beans—can raise LDL ('bad') cholesterol and slightly lower HDL ('good') cholesterol. Paper filters used in drip machines remove most diterpenes, while unfiltered methods such as boiled coffee or espresso retain higher levels. Swedish workplace coffee machines were analyzed, confirming that brewing and filtering choices markedly affect diterpene concentrations and therefore cholesterol risk.
