As a result of long research by the British scientists proved scientifically the regularity, which the majority of ordinary British consider obvious. According to researchers, the regular use of black tea reduces the restoration period after the stressful situation.

The experiment lead by employees of London University College has shown, that usual black tea, unlike the substitutes of this drink identical to taste, color and smell, promotes the reduction of the stress hormone level “hydrocortisone”.

75 volunteers have participated in the experiment. Participants have been divided on two groups, first of which was drank the usual black tea, and the second one drank the flavored drink identical to tea to taste, color and the caffeine maintenance, but deprived a lot of other components of natural tea.

During the research participants were exposed to a series of tests which performance has been integrated to the increased stressful loading. In particular, they were offered to reproduce a situation in which they were threatened with dismissal from work or charge in theft of products from a supermarket. After end of tests participants independently fixed a level of the stress, they also measured their pressure, pulse and the hydrocortisone level in blood.

Results of measurement and subjective indications of participants testified to enough high levels of the stress in both groups. And the repeated measurements lead 50 minutes later, showed that the participants received natural tea were restored much more quickly after stress, than those who received an artificial drink.

Scientists have come to conclusion, that frequent consumption of carbonated drinks by women leads to threat of osteoporosis disease.

Osteoporosis is dangerous enough, it conducts to destruction of a bone fabric owing to what bones become very fragile. According to the average parameters, 1 from 3 women and 1 from 12 men worldwide prone to osteoporosis.

According to the research lead by USDA Research center of food of person, at women daily consuming drinks of type coke density of a bone below, than at those who prefers juices or tea.

In opinion of scientists, also the caffeine increases the risk of osteoporosis disease.

According to magazine HealthDay data, approximately 55 % of Americans, basically women, are subject to disease.

The substances of cranberry juice are capable to protect an organism of a person from bacterial infections and can replace antibiotics, which become less effective because of the increased medicinal stability of pathogenic bacteria.

During long-term research work USA experts managed to reconstruct completely the biochemical mechanisms underlying numerous salutary properties of cranberry juice.

Results of the research have been presented at annual conference of the American chemical society to San Francisco.

Ability of cranberry juice to prevent bacterial infections and, in particular, urination ways infections, is known widely enough, however the nature of the biochemical interactions laying in its basis, long time remained obscure.

During the previous researches the group of scientists has come to conclusion, that substances containing in cranberries tannins alter structure of pathogenic micro-organisms cellular membrane. Under their action numerous bacteria braids are shortened and lose mobility, that considerably complicates process of an attachment of a bacterium to urination ways cells.

During new research it has been established, that under the influence of tannins the bacterium of intestinal stick E. coli changes not only the braids form, but the membrane structure, and also the form, turning from a stick in a sphere. Besides tannins deprive E. coli with ability to produce the substance “indole”, which participate in an exchange of signals between bacteria of one kind. All these metamorphoses reduce viability of pathogenic bacteria and complicate their introduction in a fabric of the struck organism.

Obtained data speak that cranberry juice or its separate components can be applied with success as antibacterial means.

The new kind of bacteria interfering formation of caries was created by the European scientists on the basis of genic engineering technology. A group of experts were carried out more of six years of research in one centre of science in Sweden, it was possible to design on the basis of a dairy bacterium its genetically changed updating, possessing ability to not admit to create of acids destroying teeth.

In a basis of the protective mechanism lays the ability of modified bacterium to make special antibodies. Numerous tests have shown that thus it is completely harmless to a human body. It is expected, that in the near future the new bacterium will be added in dairy products to guarantee to all consumers the access to a new effective way of teeth protection.

The British doctors have carried out scale research with participation of 30 thousand lying-in women and have drawn impressing conclusions. At women who use 2–2.5 litres of a liquid a day, risk of such disease as mastopatiens, decreases twice in comparison with those who manages by 1 litre.

However not any water is useful. In water pipeline water chlorine contains, and boiled water does not bring to an organism any advantage. Therefore for drinking and cooking you should buy only water in bottles from known sources. It is clean, useful and tasty. And in fact it that is necessary for young mum!
