It can give you a boost of energy, but new research finds a cup of joe can’t help preserve brain function as you age.

According to Reuters, researchers at the University of Helsinki assessed the coffee drinking habits, as well as other social, demographic, and health data of a large population of twins who were 50-years-old on average. The majority of subjects – 75 percent of men and 83 percent of women – reported drinking more than three cups of coffee a day.

Participants were screened on a yearly basis starting at age 74 to measure cognitive function and dementia.

They found no association between coffee consumption and declining cognition or dementia scores in either men or women. They did find, however, that aging was linked to declines in thinking ability.

In addition, the study, appearing in The American Journal of Clinical Nutrition, found that coffee consumption wasn’t protective in preserving brain function in middle-age.

Heart disease, diabetes and depression are associated with lower cognitive function, according to the report.

Nutritional supplements that can boost brain function and memory include B vitamins, vitamin C, vitamin E and beta carotene as well as omega-3 fatty acids and gingko biloba.
