This type of tea is very good for the heart and reduces the risk of diabetes.
Black tea is rich in antioxidants and may provide a variety of health benefits, including improved heart and gut health and a reduced risk of certain diseases.
Besides water, black tea is one of the most consumed beverages in the world.
Black tea or red tea is a type of tea. Typically, it has a stronger flavor than other types of tea such as green tea.
The name red tea comes from the color of the tea, and is popular in East Asian countries and some other places around the world.

Black tea has a stronger flavor and contains more caffeine than other teas, but less caffeine than coffee. Black tea also has many health benefits because it contains antioxidants and compounds that can help reduce inflammation in the body.
According to the Vietnam Institute of Applied Medicine, below are 10 scientifically proven health benefits of black tea:
Antioxidant
Antioxidants are known to have many health benefits. Consuming them can help eliminate free radicals and reduce cell damage in the body. This helps reduce the risk of chronic diseases.
Polyphenols are a type of antioxidant found in a number of foods and beverages, including black tea. Polyphenol groups, including catechins, theaflavins, and thearubigins, are the main sources of antioxidants in black tea and may promote overall health.
A study in mice looked at the role of theaflavins and thearubigins in black tea and the risk of diabetes, obesity, and high cholesterol. Results showed that theaflavins and thearubigins reduced cholesterol and blood sugar levels.
Improve cardiovascular health
Black tea contains another group of antioxidants called flavonoids, which are beneficial for heart health. Along with tea, flavonoids can be found in vegetables, fruits, red wine, and dark chocolate.

Consuming them regularly may help reduce many risk factors for heart disease, including high blood pressure, high cholesterol, elevated triglyceride levels and obesity.
A large review of studies found that, for each cup of tea consumed daily, there was a 4% lower risk of death from heart disease, a 2% lower risk of heart attack and other cardiovascular events, a 4% lower risk of stroke, and a 1.5% lower risk of death from all causes.
Reduces "bad" LDL cholesterol
The body contains two lipoproteins that transport cholesterol throughout the body. One is low-density lipoprotein (LDL) and the other is high-density lipoprotein (HDL).
LDL is considered the “bad” lipoprotein because it carries cholesterol to cells throughout the body. Meanwhile, HDL is considered the “good” lipoprotein because it carries cholesterol away from your cells and to the liver to be removed from the blood.
When there is too much LDL in the body, it can build up in the arteries and cause plaque. This can lead to problems like heart failure or stroke. Fortunately, some studies have found that drinking tea can help lower LDL cholesterol.
Improve gut health
Your gut contains trillions of bacteria and most of your immune system. The polyphenols found in black tea may help maintain a healthy gut by promoting the growth of beneficial bacteria and inhibiting the growth of harmful bacteria.
Additionally, black tea contains antibacterial properties that help kill harmful substances, improve gut bacteria and immunity by helping to repair the lining of the digestive tract.
May help lower blood pressure
High blood pressure can increase your risk of heart and kidney failure, stroke, vision loss, and heart attack. Fortunately, changes in diet and lifestyle can lower your blood pressure.
One study looked at the effects of drinking tea on blood pressure in people with hypertension, or high blood pressure. The review found that regular tea consumption reduced systolic blood pressure by 4.81 mmHg and diastolic blood pressure by 1.98 mmHg in people with hypertension./.
