Tea and Heart Health
There are studies that indicate the role of tea in reducing cholesterol levels and lowering the risk of heart diseases.Flavonoids in tea
Tea is rich in flavonoids, which neutralize the free radicals in the body due to their effects as antioxidants. Flavonoids present in tea play a role in improving heart health by improving the function of blood vessels and reducing overall cholesterol levels.High levels of cholesterol in the blood can be dangerous if not monitored, as it can cause a number of heart diseases and even strokes. High cholesterol results in the gradual build-up of plaque in the walls of the arteries, thereby narrowing them in time. The phytochemicals present in tea help dilate the arteries, leading to an improvement in the function of coronary vessels.
Black Tea v/s Green Tea
Consumption of tea on a regular basis is linked to a lower risk as far as heart health is concerned, and may even improve the chances of survival in case a heart attack does occur. Most of the research in this domain is linked to Black Tea consumption, but the is research that shows the positive effects of Green Tea consumption on heart health as well.
The catechins present in Green Tea play a role in lowering cholesterol. Even though Black Tea has a lower amount of polyphenols when compared with Green Tea, the reactions during the process of oxidation produce tannins that also have positive effects on heart health. Black Tea helps in maintaining healthy function of the endothelium, which in turn reduces the risks associated with heart diseases. The endothelium refers to the inner lining of the blood vessels.
While the other varieties of tea (White & Oolong) also offer health benefits unique to each one, studies show that Black and Green teas are the best as far as heart health is concerned.
