This was said after the Researchers found moderate levels of caffeine protected the
brain against rogue proteins that destroy neurons leading to memory loss.
A study of almost 1,500 Italians found moderate consumers of
the world's most popular beverage were less likely to develop mild cognitive
impairment (MCI) - commonly the first sign of dementia.
The findings add to evidence that the right amount of
caffeine - a stimulant known to sharpen alertness and boost the brain -
protects against mental decline in older age.
Mentally healthy individuals who regularly drank one or two
cups of coffee a day had a reduced rate of MCI than those who never or rarely
consumed it.
No significant association was detected between those who
habitually had more than two cups and the incidence of MCI in comparison with
those who never or rarely indulged.
The study published in the Journal of Alzheimer's Disease
also showed that increasing the amount of coffee consumption over time by more
than one cup doubled the rate of MCI compared to those who reduced it by a cup.
The rate of MCI was also about one-and-a-half times higher
than those with a constant habit of one cup-a-day.
