Consumption of green tea quickly improves function of endothelial cells which promote correct blood circulation and support work of blood vessels.

The Greek scientists from Athens Medical School have studied properties of tea, caffeine and hot water (as placebo) on vessels at 30, 90 and 120 minutes after drink. Cardiologists have fixed the top expansion of arteries on 3,9 % and activity of the blood-groove regulator 30 minutes after drinking green tea.

Favorable action of the considered kind of tea is attributed to flavonoids and their antioxidizing and anticancerogenic effects found also in red wine and cocoa. Flavonoids in green tea are more powerful, than the same structures in the black tea which is practically not having antioxidants, doctors say. According their assumptions if to drink green tea regularly several times a day, it is possible to prevent cardiovascular diseases and to lower the risk of heart death rate.

German scientists have investigated, using data of national interrogation in which 7 000 children and teenagers in the age from 11 till 17 years participated. All of them were weighed and asked to estimate the weight independently (from “too thin” up to “too thick”). After that boys and girls have filled the questionnaire, allowing to estimate quality of their life.

It has appeared that approximately 75 % of children and teenagers had a normal weight. Almost 55 % of girls and only 36 % of boys considered themselves “very thick” though only 18 % of participants of research actually had excess weight. At 7-8 % of boys and girls the weight was less norms.

At children and teenagers having excess weight, quality of their life differed in the worst party and strongly depends on their own estimation of the weight. The teenagers considered thick, had the lowered quality of the life without dependence from real weight. Especially strongly this tendency was showed at girls. At the same time, the teenagers considered the weight normal, did not lose their quality of the life even if their weight actually exceeded norm.

Also scientists have found out that the quantity of children and teenagers considering thick, last years increases more quickly, than real quantity of children and teenagers having excess weight.

In clause accompanying research, German scientist Johannes Hebebrand marks, that teenagers acquaint with powerful pressure of public opinion which orders them to be harmonious. As the great value is given to leanness, and excess weight is condemned.

Consumers admit, that they feel deceived when think, that they have bought ice-cream, and then learn, that actually they had been sold not ice-cream, but only something similar to «the frozen margarine».
