Studies funded by the Tea Trade Health Research Association suggests that black tea reduces plaque formation as well as restricts bacteria growth that promotes the formation of cavities and tooth decay. Polyphenols found in black tea kill and surpass cavity causing bacteria as well as hinder the growth of bacterial enzymes that form the sticky-like material that binds plaque to our teeth.
A Better Heart
As identified by Arab L. et al. in their 2009 research paper called 'Green and black tea consumption and risk of stroke: a meta-analysis', it is seen that regardless of people’s country of origin, individuals who consume 3 or more cups of tea had a 21% lower risk of a stroke than people who consume less than 1 cup of green or black tea per day.
Black tea contains polyphenols, which are also antioxidants that help block DNA damage associated with tobacco or other toxic chemicals. These antioxidants are different from those obtained from fruits and vegetables and therefore as a regular part of our diet they can provide additional benefits towards a healthy lifestyle.
Though a lot more research is required to confidently suggest cancer prevention techniques, some research over the years suggests that antioxidants like polyphenol and catechins in tea may help prevent some types of cancer. It has been suggested that women who drink black tea regularly have a lower chance of ovarian and breast cancer than their counterparts.
It has also been suggested that regular tea drinkers have stronger bones and lower probability of developing arthritis due to the phytochemicals found in tea.
Lower Risk of Diabetes
Based on a research study conducted by elderly people living in the Mediterranean islands it was discovered that people that had been consuming black tea on a long-term basis on a moderate level (i.e 1-2 cups a day) had a 70% lower chance of having or developing type 2 diabetes.
We all are aware and well experienced about the calming and relaxing benefits of black tea. Not only does it help slow you down after a long day, studies show that the amino acid L-theanine found in black tea can help you relax and concentrate better. Black tea has also been shown to reduce levels of the stress hormone cortisol when consumed in moderate amounts on a regular basis.
Better Immune System
Black tea contains alkylamine antigens that help boost our immune response. In addition, it also contains tannins that have the ability to fight viruses and hence keep us protected from influenza, stomach flu and other such commonly found viruses in our everyday lives.
Healthy Digestive Tract
In addition to improving your immune system, tannins also have a therapeutic effect on gastric and intestinal illnesses and also help decrease digestive activity.
Unlike other drinks that have a relatively higher caffeine content, the low amounts found in tea can help enhance blood flow to the brain without overstimulating the heart. It also stimulates the metabolism and respiratory system, as well as the heart and the kidneys.
According to a study conducted by the American Heart Association in New Orleans, people who consume black tea can reduce their bad cholesterol levels, which are responsible for heart strokes and fatal attacks. It has also been found that people who drink 3 to 4 cups of black tea every day are at a lower risk for heart problems than those who consume minimal amounts or no tea at all.
