Black Tea Good for Cancer
DNA is the genetic material that contains all cells in animals and humans which controlled all activities including the growth and reproduction of cells. In the early stages of cancer, the DNA is damaged or changed. Latter it becomes a cancer cell. Rapid growth and multiplication of cells may happen in the cancer initiation. Mutagens are agents that cause damage to DNA and cause to cancers. These mutagens are called “Carcinogens”. Some chemicals, radiation, smoke, and viruses act as carcinogens. In later stages of cancer, cell to cell signaling is needed for the multiplication of cancer cells further.

Components of black tea prevent cell to cell signaling and reduce the development of cancer. Tea has anti-angiogenesis properties that form small blood vessels. Then the blood supply for the cancer cell would be poor and their growth will dropdown.

Black Tea for Oral Health
Black tea could prevent the growth of microbes in the mouth. Both fungal and bacterial species cause some oral infections. But brewed black tea could inhibit their growth and improve oral health

Good for Diabetes
Flavanol, Myricetin which is present in black tea having mimics insulin activity. Polyphenols in tea prevent alpha-amylase activity and reduce the blood glucose level. Alpha-amylase is an enzyme that involves the conversion of starch in food to glucose in the digestive process. Therefore, drinking black tea is useful to diabetics.

Minerals in Black Tea
Tea is rich in metal elements. Therefore, by drinking tea we will be able to get many minerals. Potassium has the highest concentration in the brew according to the below chart.

Aluminium (Al) Toxicity
Tea consumption could lead to excessive intake of Aluminium and it is causing Aluminium toxicity. Because tea plants accumulate Al. tea leaves are rich in higher concentrations of Al. most of the mature leaves are accumulate Al than tender leaves. Therefore, the contribution of Al from tea to daily intake is less than 3%, and drinking tea is not cause Al toxicity.

Fluorides (F)
Fluorides absorb by the teeth from tea. Because tea contains relatively high amounts of F. fluorides causes harder to teeth and resistance to decay. However, drinking more tea with fluoridated water does not cause any adverse effects.

Iron (Fe) Absorption
Polyphenols bind with Ferrous or Ferric irons form insoluble complexes. Flavonoid is a polyphenol contained in tea. It can reduce the Fe absorption into blood vessels and they do not interact with Fe from meat or fish. It interacts only with Fe from plant sources. Therefore, in the vegetarian diet, it is advisable to drink tea either 1 ½ hours before or after a meal.
