Coffee is one of the most widely consumed beverages in the world and also one of the most widely studied. Research has linked drinking coffee to reducing type 2 diabetes and liver cancer was well as increasing your life span. Now, recent studies show that drinking coffee may reduce your risk of developing rosacea.

Rosacea is a skin disorder that affects over 16 million people in the U.S. including President Donald Trump, former president Bill Clinton and Britain’s late Diana, Princess of Wales and her son Prince William. The late comedian W.C. Fields had audiences rolling in the aisles during the early part of the 20th century, but his bulbous nose was no laughing matter. The comedian suffered from an advanced case of rosacea.

Experts don’t know what cases rosacea, normally characterized by a pink or red discoloration of the cheeks. It usually affects fair-haired women, according to Harvard Health Publishing. Sometimes you’ll see tiny bumps that resemble acne or spot a spider web of blood vessels visible just under the skin. In extreme cases, it may involve thickening of the skin.

Because it can run in families, there is a possible genetic connection. The immune system seems to be involved in the inflammation of rosacea, and other autoimmune conditions such as type 1 diabetes and multiple sclerosis may accompany rosacea, meaning abnormal immune function may also be involved. Medications such as tropical anti-inflammatory drugs and antibiotics may reduce redness and inflammation, but there is no cure for the condition.

Many people seem to be able to reduce signs of rosacea by modifying their diet to avoid trigger foods. In the past, these foods were thought to include caffeine and spicy foods.

Now a recent study challenges the connection between caffeine and rosacea. In the Nurses’ Health Study 11, scientists found that drinking coffee helps vasodilation and acts as an immunosuppressant which decreases the risk of rosacea. They published their surprising findings in the Journal of the Medical Association (JAMA) Dermatology.

After analyzing surveys from 83,000 women for over a decade, they found:

• Those drinking four or more cups of coffee per day were significantly less likely to report a diagnosis of rosacea than those who drank little or no coffee.
• Those drinking less than four cups of coffee each day were also less likely to have rosacea, although the protective effect was smaller.
• Consumption of decaffeinated coffee was not linked to a lower incidence of rosacea.
• Caffeine intake from other foods or beverages—such as chocolate or tea—had no impact on the likelihood of developing rosacea.

Experts say that while the study showed a positive link between drinking coffee and reducing the risk of rosacea, some people do suffer from heart burn, palpitations or tremors from a cup or two of Joe.
