Can Drinking 3 Cups of Coffee Boost Memory in Older Women?

Forgetfulness as you age can be frustrating—especially when it feels like your memory is slipping faster than you'd like. Many older adults wonder whether something as simple as their daily cup of coffee could make a real difference. Could your morning brew actually help preserve your mind?

Yes—according to a major study, drinking three or more cups of coffee or tea per day is linked to better verbal memory retention in older women. That specific amount showed measurable cognitive benefits, especially in word recall tests, with minimal decline over time.

The French Study on Coffee, Tea, and Memory

Published in the journal Neurology, this research was led by Dr. Ricci from France’s National Institute of Health and Medical Research (INSERM). The team surveyed around 7,000 men and women with an average age of 74, living in three French cities: Bordeaux, Dijon, and Montpellier. Researchers asked participants how many cups of coffee or tea they drank daily, then tested their cognitive abilities using a series of mental skill assessments—including specific verbal memory tasks. These tests were repeated after two years and again after four years.

What the Results Showed for Women

The key finding focused on older women. Those who consumed three or more cups of coffee or tea per day showed significantly less decline in test scores compared to women who drank just one cup per day. The most noticeable benefit appeared in verbal memory—such as remembering words or language-based information. However, researchers found no strong evidence that coffee or tea affected the risk of developing dementia within the study period, likely due to its relatively short duration.

Why Coffee May Not Help Men’s Memory

In contrast, the study found no similar cognitive benefits for older men who drank three or more cups daily. Their mental performance scores over time did not improve compared to those who drank less. Researchers speculated that women might be more sensitive to caffeine, which could explain why the positive effects on memory appeared only in female participants.

How Much Coffee or Tea Is Enough?

The threshold for cognitive benefit in women was three or more cups per day of either coffee or tea. There was no distinction made between the two beverages in the data—both were grouped together as sources of caffeine. The study tracked average consumption without specifying types of coffee or preparation methods, focusing solely on the number of cups consumed.

Frequently Asked Questions

How many cups of coffee or tea per day helped older women in the study?

Older women who drank three or more cups of coffee or tea per day showed less decline in memory test scores, especially in verbal memory. One cup per day was less effective in preserving those cognitive abilities.

Did the study find coffee helps with memory in men?

No. The research showed no memory benefits for older men who drank three or more cups of coffee or tea per day. Their cognitive scores did not improve compared to men who drank less.

What kind of memory was improved by drinking more coffee or tea?

The most significant improvement was in verbal memory—such as the ability to remember and recall words. This was measured through repeated word memory tests over a four-year period.

Could drinking coffee reduce the risk of dementia?

The study did not find strong evidence that coffee or tea reduces dementia risk. The follow-up period may have been too short to detect any significant impact on dementia development.

Why did coffee help women but not men in this study?

Researchers suggested that women may be more sensitive to caffeine, which could explain why higher coffee or tea intake was linked to better verbal memory in women but not in men.
