A study carried out in France has revealed that caffeine intake significantly reduces the risk of Alzheimer’s and mild cognitive impairment. Research conducted on participants over the age of 70 showed that those consuming more than 200 mg of caffeine per day were 2.5 times less likely to experience memory problems compared to those with low caffeine intake.
In France, a team examined data related to patients diagnosed with mild cognitive impairment or Alzheimer’s between 2010 and 2015. The clinical evaluation of 263 participants aged over 70 was conducted, and their consumption levels of caffeine-containing foods like coffee, chocolate, tea, and soft drinks were studied.
Volunteers underwent MRI scans and provided samples of blood and cerebrospinal fluid (CSF). Those consuming slightly over an average of 200 milligrams of caffeine per day were placed in the ‘low’ caffeine group, while those consuming higher amounts were classified in the “high” caffeine group.
The data obtained showed that lower caffeine intake increased the risk of mild cognitive decline associated with memory problems. Those in the low caffeine group were approximately 2.5 times more likely to be diagnosed with Alzheimer’s or mild cognitive impairment. Furthermore, protein analyses in the CSF revealed significant differences in specific types of beta-amyloid proteins in low caffeine consumers. Accumulation of beta-amyloid proteins associated with Alzheimer’s symptoms in the brain was observed more in low caffeine consumers.
According to a study published in the Alzheimer’s & Dementia journal, it is important to pay attention to when and how caffeine is consumed. For example, consuming coffee late in the day not only affects sleep but can also impact long-term neurological function.
Overconsumption of chocolate and energy drinks leads to additional sugar intake, putting cognitive health at risk.
