Aids As An Antioxidant

Black tea contains flavonoids, such as epicatechins, hearubigins, and catechins. It is a type of antioxidant. Many studies in the recent past have shown that regular intake of black tea lowers the risk of developing arterial stiffness in the heart. This is due to the presence of flavonoids.

Helps Diabetics

Diabetes is of 2 types - One which can be controlled with insulin and the other does not have any impact on blood sugar levels. For the latter, the body becomes insensitive to insulin. Studies have shown that drinking black tea for Type 2 kind of diabetes is an excellent boost. This is due to the presence of polyphenols which act as an antioxidant. This happens thanks to a certain complex biochemical reaction which helps sensitize cells to better metabolize sugar in Type 2 diabetes patients.

Lowers Cholesterol Levels

Two of the major health issues faced by people around the world are cholesterol and obesity. This is due to the eating habits and sedentary life styles. While cholesterol occurs naturally and plays a pivotal role in human body, it needs to be present in small amounts. Low Density Lipoprotein (LDL) is an important carrier of cholesterol in the human body. Moderate inclusion of black tea in a daily diet reduces LDL cholesterol by significant amounts, which therefore reduces the risk of heart diseases

Helps in Stomach Upset

You think you have an upset stomach? It could even be worse, diarrhea? Having a nice strong cup of black tea could be an instant solution. Black tea has an astringent effect on the intestinal lining. This helps in calming the inflammation in intestines and further helps in controlling diarrhea.
