1. Black Tea Improves Concentration and Reinforces Your Immune System
Studies have shown that people who drink 2 to 3 cups of black tea a day – early morning, midday and afternoon – have higher levels of concentration and mental activity than those who don’t.
Black tea can be very helpful in fighting intellectual and physical fatigue and in boosting our brain functions: it speeds up our reaction time and helps maintain mental vitality during work. All this happens thanks to the amount of theanine, greater than in other teas.
The beneficial properties of black tea are altered and amplified during fermentation process, and therefore more easily assimilated by the body and more quickly absorbed into the bloodstream. 1 cup of black tea contains 35 to 40 mg of theanine, while green tea has only 20 to 25 mg per cup.
According to a recent study published by Brigham and Women’s Hospital and Harvard University, the theanine contained in the black tea is a unique amino acid found only in tea leaves that has the ability to strengthen the immune system and help fight bacteria, viruses and fungi.
Researchers have also pointed out that drinking up to 5 cups of black tea a day may help the body increase its defense against infections, within a period of 2 to 4 weeks.
2. Black Tea Strengthens Your Heart and Protects Your Blood Vessels
The main benefits of black tea are derived from its high content of flavonoids that are powerful antioxidants.
Some researches have proven that black tea flavonoids can help prevent cardiovascular diseases and maintain blood vessels healthy. Their antioxidant power blocks the oxidation of LDL (low-density lipoproteins, known as “bad cholesterol”) in our blood vessels, thus reduces the risk of arteriosclerosis and other heart problems.
Black tea flavonoids also have vasodilator properties, helpful in improving coronary circulation and reducing blood clots. Studies have shown that drinking 2 cups of black tea a day, for 3 to 4 weeks, may greatly enhance a person’s heart health.
3. Black Tea Prevents Cavities and Strengthens Bones
Regularly drinking black tea between meals, without adding milk or sugar, can be a great ally for strong teeth, healthy gums and fresh breath.
Black tea contains polyphenols (aka flavonoids) that have antiviral properties useful in fighting harmful bacterial deposits that build up on our teeth, forming layers of dental plaque. These bacteria produce damaging acids, responsible for tooth decay, caries, gum disease and bad breath.
Fluorine has an essential role in protecting teeth from these damages: It reduces the risk of gum and tooth disease and protects tooth enamel. Black tea is helpful because it contains fluoride, a form of fluorine, which becomes active after 5 minutes infusion of tea leaves.
Some researches have also shown that people who regularly drink black tea have stronger bones, due to the estrogenic effect of the black tea flavonoids, known to help built and increase bone density.
Furthermore, fluoride contained in black tea bonds with dental and bone calcium to form calcium fluoride, important for maintaining strong bones and teeth.
