Yay, more good news for us coffee drinkers!
I am always interested in the research that is coming out with regard to coffee as a coffee drinker. Yes, so I am biased. Coffee had been considered unhealthy for many years but research over the years has shown multiple health benefits (including living longer) – I first discovered this after encountering a coffee expert who told me of all the antioxidants and natural ingredients in coffee beans – I was converted.
This research just out, though, is even more fascinating – it showed that espresso can reduce clumping of proteins in the brain that lead to Alzheimer’s – wow!
In this fascinating research by Roberto Tira and colleagues of the University of Verona in Italy – no surprise in the location there – they incubated various coffee compounds found in freshly extracted coffee and also a complete espresso compound next to tau proteins.
Tau proteins are natural occurring in the human brain but it is precisely these that end up becoming dysfunctional and clumping up to form blobs of protein that the brain can no longer clean out. This is also a key indicator of Alzheimer’s.
When these molecules from coffee were incubated alongside the proteins the fibres they formed were shorter and didn’t form into sheets suggesting that they would be less likely to form clumps. What’s more the most effective at reducing this was the full espresso compound rather than individual molecules extracted from the espresso compound.
This could be for many reasons such as having multiple molecules that are beneficial.
Obviously this was a lab test and in the human body your espresso doesn’t go directly to your brain – alas. But, nevertheless, another piece in the increasing large collection of research showing that coffee has multiple potential benefits.
Another shot of espresso for me then●

Is it just pictures of cats that we share on social media? That is a cliché – most of social media does not have post of cats on them and all manner of things are shared.
