Don’t drink coffee and don’t stop drinking your favorite coffee and tea combination.
It’s good for you.
Results from a new study show that regular consumption of both caffeinated and decaffeinated coffees and teas is associated with an 11 percent lower risk of developing dementia. The findings were published in Neurology.
Just how close are humans to humanity’s oldest ancestor? Well, getting a coffee from the original place it’s brewed now, rather than Neanderthal times, would be easier said than done.
“Genetic variation in the caffeine source of coffee has also been found to predict risk of dementia, and in light of the increasing prevalence of dementia and frailty in elderly populations, the safety of decaffeinated coffee, tea, and cocoa is of interest to researchers,” said lead author Yuichiro Nagahara, an associate professor of medicine at Stanford University School of Medicine.
“Using a robust cohort-based database, our team was able to examine the relative risk of dementia among regular coffee and tea drinkers,” he continued. “Due to the large sample size of more than 100,000, the analysis included data on participants who had ever had at least one coffee or tea.”
For the study, the researchers combined data from the Nurses’ Health Study with the Health Professionals Follow-up Study. They looked at data from 106,854 middle-aged adults who were followed for an average of 11.5 years. During that time, 647 cases of dementia were diagnosed.
Nagahara said further research is needed to see if the correlation holds up.
“However, this is the first study to investigate this link, and more research is needed to confirm these findings and determine the mechanisms underlying these associations,” he said.
