Drinking Tea, Coffee Cuts Down Risk Of Stroke, Dementia: Study

There is no other drug that has brought such a huge change in how humans function as caffeine. A nervous system stimulant, caffeine keeps you alert, diminishes fatigue, and improves performance, studies have shown. There are several reasons why people drink tea and coffee, the primary sources of caffeine. These beverages often work as mood boosters, improve productivity and also provide a medium for people to socialize. If there weren’t enough reasons to consume these beverages, one more has joined the fold. A large-scale study conducted in the United Kingdom has shown that drinking tea and coffee can cut down your risk of stroke and dementia.

Study On Tea & Coffee

Moderate consumption of tea and coffee can lessen the risk of stroke and dementia, the study, ‘Consumption of coffee and tea and risk of developing stroke, dementia, and poststroke dementia: A cohort study in the UK Biobank’, published in the PLOS Medicine journal found out.

  • Stroke is a medical complication in which blood supply to a part of the brain gets interrupted. As a result, tissues in the brain cannot get oxygen and other nutrients. The brain cells start dying in minutes and, if left untreated, can lead to disability and even death.
  • Dementia is a syndrome that affects a person’s memory, thinking, and reasoning.

For this study, 365,682 UK residents between the ages of 50 and 72 reported their tea and coffee consumption data. The researchers found that drinking 2-3 cups of coffee with 2-3 cups of tea caused a 32% lower risk of stroke. The same led to a 28% lower risk of dementia. Not just that, drinking either tea or coffee or both cut down the risk of post-stroke dementia.

Both the beverages contain polyphenols. This plant-based compound is known to lower inflammation and make blood vessels healthy, as per Harvard Health.
