Researchers found that tea and coffee consumption was associated with lower dementia and stroke risk.
The study looked at 365,682 individuals aged 50-74 years old, and found that people who drank 2-3 cups of coffee or 3-5 cups of tea per day, or a combination of 4-6 of coffee and tea, had the lowest incidence of dementia and stroke. Tea and coffee drinkers had a 32 percent lower risk of stroke and 28 percent lower risk of dementia.
The authors write the following about the mechanisms potentially behind this relationship:
First, coffee is the primary source of caffeine and contains phenolics and other bioactive compounds with potential beneficial health effects. Likewise, tea contains caffeine, catechin polyphenols, and flavonoids, which have been reported to have neuroprotective roles such as antioxidative stress, anti-inflammation, inhibition of amyloid-beta aggregation, and antiapoptosis.
So, happy sipping!
