Drinking This Much Coffee Daily Could Add Years to Your Life: Insights Into New Study

Previous studies have shown that moderate coffee consumption can be heart healthy – as long as over-consumption of caffeine is avoided. The latest study gives coffee lovers another reason to enjoy their daily java. New research published in Ageing Research Reviews has found that drinking coffee could actually help you live longer.

The study indicates that three cups of coffee a day could add an extra 1.8 years to your life, while also enhancing your overall health.

The new study’s authors analyzed 85 previous studies from across Europe, the Americas, Australia, and Asia, involving hundreds of thousands of participants. The researchers examined the relationship between coffee consumption and mortality rates, as well as health indicators such as inflammation and metabolism. They also accounted for factors like smoking and alcohol consumption to isolate coffee's direct impact on health.

Adedapo Iluyomade, M.D., preventive cardiologist at Baptist Health Miami Cardiac & Vascular Institute, explains that the benefits of coffee extend beyond just a caffeine boost.

“Regular coffee consumption has been associated with a reduction in all-cause mortality due to its protective effects against several major causes of death, including cardiovascular diseases, stroke, cancer, and respiratory conditions,” said Dr. Iluyomade. “Coffee contains bioactive compounds such as caffeine and chlorogenic acids, which mitigate inflammation, oxidative stress, and metabolic dysfunction, thereby promoting healthier aging and longevity.”

Oxidative stress refers to a condition that may occur when there are too many unstable molecules called free radicals in the body -- and not enough antioxidants to get rid of them.

Coffee’s Impact on Health and Longevity

The study found that moderate coffee drinkers were at a lower risk for several chronic conditions, including cardiovascular disease, stroke, some cancers, diabetes, dementia, depression, and frailty.

“Most studies indicate that the optimal intake for longevity benefits lies around 2 to3 cups per day,” Dr. Iluyomade said. “This level maximizes the health benefits while minimizing potential adverse effects.”

The study indicates that moderate coffee consumption is associated with a reduction in all-cause mortality. The combination of caffeine and other compounds like chlorogenic acids likely contributes to these health benefits.

“The key takeaway is that moderate coffee consumption is not only safe, but can be part of a healthy lifestyle that promotes longevity and reduces the risk of chronic diseases,” said Dr. Iluyomade. “These findings are important as they challenge old misconceptions about coffee being harmful and instead position it as a functional food with significant health benefits.”

Moderation is Key

While the study supports the health benefits of coffee, Dr. Iluyomade cautions against overconsumption. He stresses that consuming coffee with excessive sugar or cream can negate its positive effects. "These findings emphasize the importance of consuming coffee without excessive additives, which can offset its health advantages," he explains.

Drinking more than 4 to 6 cups per day can lead to unwanted side effects. "Excessive coffee consumption may increase the risk of anxiety, restlessness, insomnia, and gastrointestinal discomfort," Dr. Iluyomade warns. Moreover, if you suffer from severe high blood pressure, drinking more than two cups of coffee a day may double your risk of death from cardiovascular disease, according to other studies.

If you're wondering whether coffee is right for you, Dr. Iluyomade recommends consulting with your doctor, especially if you have any underlying health conditions. For most people, however, 2 to 3 cups of coffee a day can be a simple and enjoyable way to boost your health and potentially add years to your life.
