Many people start their day with a cup of coffee before eating any food, but is this practice actually healthy?
Dr. Brunilda Nazario, Chief Medical Officer at WebMD, explains that while coffee is most commonly associated with caffeine, it is actually composed of a wide variety of chemical compounds, and its health benefits depend on several factors.

Nazario clarifies that the exact composition of your coffee depends on the origin of the beans and the brewing method used. However, the most active component providing that much-needed morning boost is caffeine. Caffeine stimulates the brain, serving as an effective way to wake up feeling energized and ready to start the day, making it the most studied component of the beverage.
Dr. Nazario points out that drinking coffee daily can improve overall health. Studies suggest that enjoying coffee may lower the risk of developing certain conditions—such as diabetes, heart disease, and potentially fatty liver disease—compared to non-coffee drinkers.
However, negative side effects can occur. If you enjoy unfiltered coffee, such as Turkish or French press coffee, it is worth noting that these brews contain compounds that can elevate LDL (bad) cholesterol levels.
Nazario notes that outcomes largely depend on total caffeine intake; consuming fewer than one or two cups a day is generally considered safe and unlikely to cause issues.
Nevertheless, caffeine is absorbed rapidly and completely in the stomach. Drinking it on an empty stomach can intensify its effects, causing some individuals to experience side effects such as a rapid heart rate, nervousness, headaches, an upset stomach, or nausea, according to Dr. Nazario.
"Enjoy your coffee, but listen to your body!" Nazario advises. She highlights that great low-caffeine alternatives exist that still provide an energy boost—such as black tea, green tea, or matcha—each offering its own distinct flavor profile and health benefits.
