Tea inversely related to coronary heart disease risk
In 1985 the average consumption of black tea in the Zutphen men was approximately 3 cups per day. Elderly men who drank more than 4 cups of tea per day had a 60% lower risk of fatal CHD after 5 years of follow-up, when compared to those who drank less than 2 cups of per day.
Higher tea consumption associated with lower stroke incidence
The average tea consumption in the period 1960-1970 was related to non-fatal and fatal stroke incidence over the next 15-years. Middle-aged men who drank on average at least 5 cups of tea per day had a 3 times lower stroke incidence than those who drank less than 2.5 cups per day.
Potentially, the effects of tea on CHD and stroke might be due to its high content of flavonoids – compounds with potential beneficial properties.
