Tea and Health

Research suggests drinking tea as part of a healthy diet may help to maintain your health. Now there's even more reason to love your cup of tea!

Heart health

Some studies have shown drinking 2 to 3 cups per day of black or green tea helps to maintain healthy vascular function (your circulatory system).1-4  As well, there is evidence that drinking tea and flavonoids reduces the risk of stroke. Results presented at the 2009 American Stroke Association's International Stroke Conference, found a 21% reduction in stroke risk associated with drinking more than three cups of tea daily (black or green).5 

Hydration

Canada's Food Guide encourages satisfying your thirst with water as a great-tasting, calorie-free way to help you stay hydrated, especially in hot weather or when you are very active.6 Since tea is 99.5% water, it can count towards your fluid intake for the day - plus it tastes great!

Nutrition experts agree that calorie-free tea is a delicious beverage for hydration.7,8 Hydration is important for concentration, alertness, speed and sports performance.7,8  Healthy adults should consume between 9 and 13 cups of fluids every day.9

It is a commonly held myth that tea acts as a diuretic because of its caffeine content, but research shows that the levels of caffeine in regularly consumed amounts of tea do not lead to dehydration. In fact, the fluid in tea contributes to hydration – it’s hydrating, not dehydrating.7,8,10  A typical cup of tea contains approximately 50 mg of caffeine, which is half the caffeine in a typical cup of coffee.

Cognition

You already know that feeling: how tea can refresh you and provide a break that helps you feel relaxed, focused and alert. Studies found that drinking tea may help maintain cognitive focus and improve alertness throughout the day.11,12

Note that while tea is a natural source of flavonoids, it is not a substitute for fruits or vegetables which provide a wide range of nutrients such as flavonoids and essential vitamins and minerals. Please consult your doctor regarding a diet/nutritional plan that is right for you.
