TUESDAY, Nov. 23, 2021 (HealthDay News) — Coffee and tea consumption separately and in combination are associated with a reduced risk for developing stroke and dementia, according to a study published online Nov. 16 in PLOS Medicine<\/em>.<\/p>\n Yuan Zhang, from Tianjin Medical University in China, and colleagues examined the correlations of coffee and tea consumption with the risk for developing stroke and dementia in a study involving 365,682 participants aged 50 to 74 years from the U.K. Biobank.<\/p>\n The researchers found that 5,079 participants developed dementia and 10,053 developed stroke during a median follow-up of 11.4 years. There were nonlinear associations for coffee and tea with stroke and dementia; the lowest hazard ratio for incident stroke and dementia was seen for coffee intake of two to three cups\/day, tea intake of three to five cups\/day, or a combined intake of four to six cups\/day. Drinking two to three cups of coffee and two to three cups of tea per day was associated with a significantly lower risk for stroke and dementia compared with not drinking tea and coffee (hazard ratios, 0.68 and 0.72, respectively). A lower risk for ischemic stroke and vascular dementia was seen for the combination of tea and coffee consumption. The combination also correlated with a lower risk for poststroke dementia, with the lowest risk seen for daily consumption of three to six cups of coffee and tea (hazard ratio, 0.52).<\/p>\n “Whether the provision of such information can improve stroke and dementia outcomes remains to be determined,” the authors write.<\/p>\n
