Tea and cardiovascular disease

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 tea 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.

Chronic diseases and all-cause mortality

The relations of different chronic diseases with all-cause mortality was studied from middle-age onwards in the Seven Countries Study and in old age in the FINE Study.

Flavonols and cardiovascular disease

In 1992 it was found for the first time that a high intake of flavonols was associated with a 68% lower 5-year fatal CHD risk. This result was confirmed using 10-year mortality data.
