The Common Drink That Reduces Alzheimer’s Risk


The Common Drink That Reduces Alzheimer’s Risk post image

The
common drink contains compounds called phenylindanes that may help protect
against dementia.
Drinking
coffee could protect against both Alzheimer’s and Parkinson’s, new research
suggests.
The
study looked at compounds in coffee called phenylindanes, which may help
protect against dementia.
Higher
levels of phenylindanes typically make coffee taste more bitter.
Dr Donald Weaver, study co-author, said:
“Coffee
consumption does seem to have some correlation to a decreased risk of
developing Alzheimer’s disease and Parkinson’s disease. But we wanted to
investigate why that is — which compounds are involved and how they may impact
age-related cognitive decline.”
The
study examined how phenylindanes interact with two proteins that are
critical to the development of Alzheimer’s and Parkinson’s.
The
results showed that phenylindanes inhibit both beta amyloid and tau
proteins.
The
researchers also compared dark roast, light roast and decaffeinated coffees.
It
found that dark roasts had the highest quantities of phenylindanes.
Caffeine,
though, made no difference, explained Dr Ross Mancini, the study’s first
author:
“The
caffeinated and de-caffeinated dark roast both had identical potencies in our
initial experimental tests. So we observed early on that its protective effect
could not be due to caffeine.”
Dr Weaver said it is a major advantage that
coffee is a natural crop:
“Mother
Nature is a much better chemist than we are and Mother Nature is able to make
these compounds. If you have a complicated compound, it’s nicer to grow it in a
crop, harvest the crop, grind the crop out and extract it than try to make it.”
More work will be required before therapies
can be developed, Dr Weaver said:
“What
this study does is take the epidemiological evidence and try to refine it and
to demonstrate that there are indeed components within coffee that are
beneficial to warding off cognitive decline. It’s interesting but are we
suggesting that coffee is a cure?
Absolutely
not.”
The
study was published in the journal Frontiers in Neuroscience (Mancini
et al., 2018).
