According to a review published in the Journals of Gerontology by the University of Wisconsin, coffee may reduce the risk of dementia in older women. The findings are the result of an examination of 6,467 participants in the Women’s Health Initiative Memory Study.
The study examined how these postmenopausal women over the age of 65 were affected by their caffeine intake, regardless of whether it came from tea, coffee, or sugary beverages.
Over the course of 10 years of follow-up data, 388 of the original cohort of participants developed dementia. Those who consumed more caffeine than average were less likely to be diagnosed than those who consumed less caffeine than average.
Dr. Ira Driscoll, the study’s lead author, stated, “The mounting evidence of caffeine consumption as a potentially protective factor against cognitive impairment is exciting because caffeine is an easily modifiable dietary factor with few contraindications.”
