Has science finally made up its mind about coffee’s health benefits?
Doctors used to warn coffee drinkers. Now research reassures them
Coffee may have finally earned its reputation as a health-boosting beverage, according to recent research. Doctors once cautioned coffee consumers, but new studies suggest the drink could lower dementia risk, protect the liver, and improve gut health. The U.S. Food and Drug Administration recently declared black coffee a "healthy" food.
The American Heart Association also confirmed coffee's heart-healthy properties, linking it to reduced risks of heart attack, diabetes, stroke, and irregular heartbeat for those who drink up to five cups daily. Gregory Marcus, a cardiologist and lead author of the AHA statement, says the evidence has been "shocking" in its breadth of positive effects.
Coffee is the most consumed beverage in the U.S., with about two-thirds of adults drinking it daily. Scientists believe the research keeps evolving because of advancements in statistical methods and the growing use of prospective cohort studies, which follow large groups of people over many years to track health outcomes. However, researchers caution against confusing correlation with causation and emphasize the importance of considering individual differences in metabolism and health when assessing the impact of coffee consumption.
