Health Benefits of Black Tea

Black tea is not only a non-sweetened or less-calorie drink but also provides several health benefits as it contains powerful groups of polyphenols including epigallocatechin gallate, theaflavins, thearubigins, an amino acid L-theanine, and several other catechins or flavonoids which provide protection against the onset of several chronic disorders.

A cohort of ~500,000 people in the UK, age 40-69, followed for 11 years, had 13% reduced death with 2 cups of tea (or more, mostly black), less heart disease and stroke. In the new study, the researchers found that people who consumed two or more cups of tea per day had a 9% to 13% lower risk of death from any cause than people who did not drink tea. Higher tea consumption was also associated with a lower risk of death from cardiovascular disease, ischemic heart disease, and stroke. The association was seen regardless of preferred tea temperature, the addition of milk or sugar, and genetic variations affecting the rate at which people metabolize caffeine.

Benefits of black tea:

## Higher tea intake was associated with lower mortality risk among those drinking 2 or more cups per day, regardless of genetic variation in caffeine metabolism.

## Black tea is rich in antioxidants that may provide benefits including improved heart and gut health, lowered “bad” LDL cholesterol, blood pressure, and blood sugar levels. Consuming antioxidants may help decrease the risk of chronic disease and improve your overall health.

## Hypertension or high blood pressure is very common and is either directly or indirectly linked with several deadly complications such as heart failure, heart attack, stroke, kidney damage, and a risk of atherosclerosis.

## Studies also show that long-term drinking black tea results in the improvement of blood pressure either from lower or higher sides.

## Larsson et al. performed an extensively study on 74,961 stroke patients during the course of 10.2 years and concluded that drinking four or more cups of black tea on a daily basis inhibited the risk associated with stroke.

## Way et al. reported that black tea polyphenol theaflavins perform chemoprotective action against hormone-dependent breast tumors.

## Black tea contains caffeine and an amino acid called L-theanine. This amino acid increases alpha activity in the brain, which can help improve focus and alertness.
