Research studies can often be very confusing, so much so that we don’t know who to listen to anymore. Is eating bread good for you or should do clear the last crumb out of your house? Is it healthy to drink a glass of wine occasionally or should you fear it like the devil? Updates upon updates make our heads hurt – and even then we’re not sure if an Advil would help or make us terrible addicts.
Previous studies have demonstrated that drinking coffee might be a good habit that could help lower the risk of liver disease and type-2 diabetes.
However, a more recent research suggests that it’s misleading to offer coffee as an all-round protective shield, as its effect is closely related to the way one’s coffee consumption habits modify over time.
More than 1,400 subjects were evaluated by a team of researchers from the University of Bari in Italy, all of whom were 65-84 of age. Their analysis revealed that sane senior subjects who changed their routine by increasing their coffee consumption over time – more than a cup of coffee each day – were roughly twice as likely to develop mild cognitive impairment (MCI) as those who had reduced the habit to less than a cup of coffee each day.
Researchers noticed that the coffee’s acidity, as well as the stimulating effect it has on people, had to be taken under careful consideration before claiming that increasing one’s coffee consumption also increases protection against some diseases.
According to the researchers, more extensive studies with longer follow-up periods are required before a clear conclusion can be reached, studies which would also focus on other potential bias and confounding sources. Diet-related prevention has the potential of becoming one of the most promising methods of fending off dementia and Alzheimer’s disease.
Researchers also found that consuming one or two cups a day have a decreased risk of developing MCI than subjects who reported they habitually rarely consumed coffee. Mild cognitive impairment represents a well-known risk factor for Alzheimer’s disease, manifesting in a gradient decline of thinking and memory skills.
In conclusion, the others explained that regular and moderate coffee intake might represent a neuroprotective shield against MCI; however, the long-term effect of caffeine on one’s mental status can only be found from neuroimaging studies based on experimental data.
