Black tea and its effects on health
Consumption of tea in Britain and all over the world

With the exception of water, tea is the second most consumed liquid in the world. In the United Kingdom, China and some country this beverage was consumed at least more than 350 years, and it is estimated that more than three-quarters of the population drink tea per day. There is no distinction the consumption of tea between the sexes, men and women is in similar quantities to drink, but people over 50 years, drink twice as much that persons under 25

Another interesting fact is that 46% of people prefer to drink their tea without sugar. The vast majority of people in the UK (and most of the western world, drink their tea black fermented in the form).

Antioxidants in tea

There are many things in the tea are known for effects on health essential oils, including anti-oxidants, minerals, caffeine and vitamins. Black tea contains about 200 mg of flavonoids and drinking tea in the United Kingdom is contributing to more than 80% of all days of the flavonoids. Because of the fermentation of black teas, the oxidised tea, black tea contains polyphenols such as theaflavins and thearubigins, larger quantities that catechine monohydric phenols, they are much more abundant in green tea. componamts the principal of the black teas are:

1. Thearubigins: You are 12 to 18% of the dry mass of the tea
2. Catechine in the form of epigallocatechin gallates (10-12%)
3. Methylxanthine: Caffeine (8 a.m. to 11 p.m.%)
4. Favonols: as quercetin, rutin and Keampherol (6-8%)
5. Others, such as minerals, vitamins, amino acids and phenolic acids.
Medical benefits of black tea

One assumes that the consumption of most of these components in May, the benefits for health. The consumption of black tea flavonoids with many aspects of health, the benefits for the health of the tea included, but not only to minimize the risk of coronary heart disease, reduce LDL cholesterol, boost responses inflammatories. Thanks to their skills antioxidants such as flavonoids may also play a role in the prevention of cancer by reducing the number of free radicals damage the DNA.

Despite their many advantages, it is often that black tea has many negative aspects such as the impact on the health of bones, water, and the content of caffeine, that’s the idea.

Black tea is by about three-quarters of the UK population. It is known that many important effects on health as positively as to reduce the risk of heart disease and cancer, and those who are negative, especially the thought of caffeine content of the product. Search by Gardner et al have a look at the whole literature on the consumption of black tea and seven areas of health.

Is black tea drinking, the risk of coronary heart disease?

What follows is a small wagon on its conclusions on the most common cause of deaths in the UK, coronary heart disease.

There have been many reports in the context of tea with a reduction in deaths from coronary heart disease. Among the many reports on the issues, not all are used, as they are the effect of the flavonoids that have those in black tea, or tests, the specific areas of coronary heart disease, such risk factors or that the examination of the diet.

After the elimination of all research, not related to their strict criteria, Gardner and his colleagues were able for 21 studies that a certain type of connection (good, bad or indifferent) between black tea and cardiovascular disease.

The analysis of documents epidemiological research has suggested that consumption of three cups of tea per day (approximately one glass, and the quantity that is consumed on average in the United Kingdom) could pose the risk of coronary heart disease nearly 11%. Although there have been some epidemiological documents not supported the findings of this link between the consumption of black tea and the risk of coronary heart disease, he believed that these documents are not taken into account factors such as smoking, weight and the low social status of respondents.
Scientific basis of the relationship between the black tea and coronary heart disease

It is believed that the relationship between drinking three cups of black tea per day and a reduction in the risk of coronary heart disease is expected to correct, as there is a biochemical explanation of the phenomenon. Polypehnols in black tea are very strong antioxidants. The nature of the antioxidants in black tea, flavonoids, it has been shown by the oxidation of LDL cholesterol. Moreover, experience has shown that black tea, the flavonoids are able to improve the coronary vasodilatation and reduce clot formation.

Other components in black tea, may also be involved in the soundness of the relationship between black tea and the reduction of the risk of heart disease, such as manganese May the risk of coronary disease affecting the function of the heart muscle.
