A new scientific study has found that consuming moderate to large amounts of caffeine daily could reduce the risk of developing Alzheimer’s disease.Alzheimer.
The study, carried out by French scientists and published in the journal Science Alert, confirmed that caffeine reduces the levels of certain specific proteins in the cerebrospinal fluid, which are associated with Alzheimer’s disease.
Researchers analyzed data from 263 people aged over 70, suffering from mild cognitive impairment or Alzheimer’s disease between 2010 and 2015.
The team clinically assessed the participants and took a detailed record of their consumption of foods and drinks such as coffee, chocolate, tea and soda, to measure the amount of caffeine consumed each day. They also took MRI scans of their brains and collected samples of blood and cerebrospinal fluid.
Researchers found that consuming more than 200 milligrams of caffeine per day (the equivalent of a cup of coffee or tea) reduced the risk of cognitive decline and memory loss, while lowering levels of related proteins to Alzheimer’s in the cerebrospinal fluid.
The study noted that “people in the group that consumed very little caffeine were 2.5 times more likely to have mild cognitive impairment with memory loss or Alzheimer’s disease, compared to those who consumed more than 200 milligrams per day. »
An in-depth analysis of proteins in the participants’ cerebrospinal fluid revealed “significant differences in the concentrations of certain forms of beta-amyloid proteins, which are associated with Alzheimer’s disease.” Those who consumed less caffeine had higher concentrations of these proteins than those who consumed moderate to large amounts. »
However, the study cautions against consuming caffeine late in the day because it can disrupt sleep, which could negatively impact long-term neurological health.
She also points out that excessive consumption of chocolate and energy drinks increases blood sugar levels, which poses a risk to cognitive health.
