BENEFITS OF BLACK TEA
Here are 10 health benefits of black tea, all supported by science.
1. Has antioxidant properties
Antioxidants are known to provide a host of health benefits.
Consuming them can help remove free radicals and decrease cell damage in the body. This ultimately may help decrease the risk of chronic disease
2. May boost heart health
Black tea contains another group of antioxidants called flavonoids, which benefit heart health.
Along with tea, flavonoids can be found in vegetables, fruits, red wine, and dark chocolate.
Consuming them on a regular basis may help reduce many risk factors for heart disease, including high blood pressure, high cholesterol.
SUMMARY
Black tea contains flavonoids, which are beneficial for heart health. Studies have found that regularly drinking black tea may help reduce the risk of heart disease.
3. May lower “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 transports cholesterol to cells throughout the body. Meanwhile, HDL is considered the “good” lipoprotein because it transports cholesterol away from your cells and to the liver to be removed from the bloodstream.
When there is too much LDL in the body, it can build up in the arteries and cause waxy deposits called plaques. This can lead to problems like heart failure or stroke.
Fortunately, some studies have found that consuming tea may help reduce LDL cholesterol.
SUMMARY
LDL and HDL are two types of lipoproteins that carry cholesterol throughout the body. Too much LDL in the body can increase the risk of heart disease and stroke. Studies have found that black tea may help reduce LDL levels, but results are mixed.
4. May improve gut health
Studies have found that the type of bacteria in your gut may play a significant role in your health.
While some of the bacteria in your gut are beneficial for your health, some are not.
In fact, some studies have suggested that the type of bacteria in your gut may play an important role in reducing the risk of certain health conditions, such as inflammatory bowel disease, type 2 diabetes, cardiovascular disease, obesity, and even cancer (13Trusted Source).
In addition, black tea may contain antimicrobial properties that kill off harmful substances and improve gut bacteria and immunity by helping repair the lining of the digestive tract.
5. May help reduce blood pressure
High blood pressure can increase your risk of heart and kidney failure, stroke, vision loss, and heart attacks. Fortunately, changes in your diet and lifestyle can lower your blood pressure .
One review of well-designed studies looked at the effects of drinking tea on blood pressure in people with hypertension, or high blood pressure.
The review found that regular tea intake helped lower systolic blood pressure by 4.81 mm Hg and diastolic blood pressure by 1.98 mm Hg in people with hypertension . Further, those who drank tea regularly for longer than three months experienced even greater decreases in both systolic and diastolic blood pressure.
Drinking black tea on a daily basis, as well as incorporating other lifestyle modifications like stress management strategies, may benefit those with high blood pressure.
6. May help reduce the risk of stroke
A stroke can occur when a blood vessel in the brain is either blocked or ruptures. It’s the second leading cause of death worldwide .
Fortunately, 80% of strokes are preventable. For example, managing your diet, physical activity, blood pressure, and not smoking can help reduce the risk of stroke .
7. May lower blood sugar levels
Elevated blood sugar levels may increase your risk of health complications, such as type 2 diabetes, obesity, cardiovascular disease, kidney failure, and depression .
Consuming large amounts of sugar, particularly from sweetened beverages, has been shown to increase blood sugar values and the risk of type 2 diabetes .
When you consume sugar, the pancreas secretes a hormone called insulin. Insulin allows the sugar to enter cells, including muscle and liver cells, to be stored as energy, or glycogen. When the body need to use energy, a different hormone, glucagon, is released to help the body break down glycogen to release energy. If you consume more sugar than your body has space to store a glycogen, then the excess sugar gets stored as fat.
8. May help reduce the risk of cancer
Over 100 different types of cancer exist, and some are not preventable.
Nevertheless, the polyphenols found in black tea may help slow the development of certain types of cancer and promote cancer cell death.
One rigorous review of studies looking at the effects of tea on cancer risk concluded that drinking tea is associated with a lower risk of oral cancer.
9. May improve focus
Black tea contains caffeine and an amino acid called L-theanine, which can improve alertness and focus.
L-theanine increases alpha activity in the brain, resulting in relaxation and better focus.
SUMMARY
Black tea can help improve focus due to its content of caffeine and an amino acid called L-theanine. This amino acid increases alpha activity in the brain, which can help improve focus and alertness.
10. Easy to make
Not only is black tea good for you, it’s also simple to make.
