If right now you’re waiting for the kettle to boil to make a coffee, or even better you’ve just sat down with a steaming hot mug of strong coffee then we’ve got some good news for you.

It seems every day there’s another story telling us why we shouldn’t eat this, or drink that but new research has revealed that coffee is not only good for the brain but the skin too.

The first study which caught our eye was published in the JAMA Dermatology journal, which found that those who drink coffee are at less risk of rosacea than those who don’t.

But, since this report was published though, the news has got even better with the latest reports that coffee can help to protect you from both Alzheimer’s and Parkinson’s disease.

"Coffee consumption does seem to have some correlation to a decreased risk of developing Alzheimer's disease and Parkinson's disease."

Dr Donald Weaver, Co-director of the Krembil Brain Institute

“But we wanted to investigate why that is — which compounds are involved and how they may impact age-related cognitive decline.”

Strangely though, this has nothing to do with the caffeine, with decaf also offering similar beneficial properties – it seems though the key is dark roasted coffee beans!

“The caffeinated and de-caffeinated dark roast both had identical potencies in our initial experimental tests,” says Dr Ross Mancini, a member of the research team.

“So we observed early on that its protective effect could not be due to caffeine.”

Doctors identified a group of compounds known as phenylindanes, which are a product of the roasting process, which inhibit the two protein fragments that are common in Alzheimer’s and Parkinson’s from clumping together.

“It’s the first time anybody’s investigated how phenylindanes interact with the proteins that are responsible for Alzheimer’s and Parkinson’s,” Dr Mancini explained.

“The next step would be to investigate how beneficial these compounds are, and whether they have the ability to enter the bloodstream, or cross the blood-brain barrier.”

So, drinking more coffee could be key to preventing dementia and while you’re increasing your intake it won’t be having a negative effect on your skin.

As well as having immunosuppressant effects, caffeine that comes from coffee (and not energy drinks) also decreases vasodilation – or for you and me decreases the dilatation of blood vessels, which in turn also decreases blood pressure.

The study, of more than 82 000 participants, found that a higher caffeine intake was associated with lower rosacea risk.

Overall, participants who drank 4 cups of coffee per day were less likely to develop rosacea compared with participants who did not drink coffee. But, this association was not found for caffeine intake from other food sources (tea, soda, and chocolate).
