You wake up in the morning, roll out of bed, and start the coffee. Soon the smell of freshly made java fills the room, and you’re ready to begin your day.

But your morning cup of coffee might be doing much more than keeping you awake at work. A new study published in the journal Cancer indicates that drinking coffee and tea correlates with a lower risk of mouth, throat, and head and neck cancers.

Researchers analyzed data from 14 published studies involving more than 9,500 people with head and neck cancer and nearly 16,000 healthy folks. The investigation found that those who drank more than four cups of coffee each day — compared with those who didn’t drink coffee at all — had a 17% lower risk of head and neck cancer, 30% lower risk for mouth cancer, and 22% lower risk of throat cancer.

It wasn’t the caffeine that tamped down the lowered risks. Decaffeinated coffee was associated with a 25% lower risk of mouth cancer. This was supported by earlier studies, which have found that drinking coffee suppresses biological activity that can trigger cancer development.

Moreover, the researchers found, drinking one cup or less of tea every day lowered the risk of head and neck cancer by 9%. But, with tea, too much of a good thing is not necessarily better. In fact, it can be detrimental.

The study found that consuming more than 1 cup of tea a day is associated with a 38% higher risk of throat cancer.

That higher risk is likely caused by acid reflux, which has long been associated with throat cancer.

So, brew your coffee with pride, knowing that it not only perks you up but could help you avoid cancer with each cup.
