Caffeine significantly improves a person's memory, making it less forgetful and improves long-term memory consolidation during the day after he drank one or more cups of coffee.

Neuroscientists say about this in an article published in the journal Nature Neuroscience.

"We always knew that caffeine improves brain function, but no one tried to find out how it works in our memory and mental abilities, and whether he affects the ability to remember the information. The first time we were able to establish that caffeine reduces our forgetfulness over 24 hours "- said Michael Yassa of Johns Hopkins University in Baltimore (USA).

Yassa and his colleagues uncovered the positive effect of caffeine on human memory for example volunteers, tasks for memory. This experiment was conducted in two stages - first, the participants considered a set of pictures for a few minutes, after which the researchers asked them to eat real or dummy pill with caffeine.

A day later, researchers showed his players a new set of pictures and asked them which ones they met yesterday, and which of them were similar but not identical to the old objects. Such an approach, according to the authors, was strong enough "load" the brain of volunteers and help scientists to separate all the side effects and the statistical "noise."

It was found that volunteers who took pills with caffeine present, about 30% more likely to recall correctly the pictures and found differences in sets of images. This fact is believed to neuroscientists, suggests that caffeine improves our memory and makes us less forgetful.

"As our next step, we try to figure out how caffeine improves brain using MRI and other techniques for monitoring the work of the brain. Furthermore, we know that caffeine is often associated with longevity and high resistance to Alzheimer's disease .

Steaming cup of coffee or tea in the morning not only cheer you, but stand on guard your liver!

A team of researchers from Duke University (North Carolina, USA) concluded that caffeine reduces the risk of fatty liver (hepatic "obesity") in patients with non-alcoholic liver disease.

According to statistics, 70% of people suffering from diabetes and obesity , eventually become "happy" owners of steatosis. Unfortunately, the radical cure of the disease does not exist, even though it may provide some degree of control with diet and exercise.

The research team led by Dr. Ian Paul and Rohit Sinha, conducted their experiments on cell cultures and laboratory animals. It turned out that increasing the proportion of caffeine in the diet past contributed to the accelerated metabolism of fat in the liver cells. The authors concluded that the people in order to achieve the above effect should drink four cups of tea or coffee a day.

"We have become true pioneers in this area: to have no details have not studied the effect of caffeine on fat metabolism in the liver. "Tea and coffee is so firmly established in our daily lives that the opening of any useful properties of these drinks is very good news, especially given the prevailing among the people regarding their stigmatization."

The authors hope that guided their research, pharmacologists will begin to develop drugs based on caffeine, which would be devoid of the typical side effects of the latter, but would maintain a positive effect on the liver.

Moreover, in the long term this could become the foundation for a whole stratum of scientific research devoted to the potential therapeutic use of caffeine. Results of this study were published in the journal Hepatology.

Several years ago, scientists have published data that eating broccoli and planteyna can be an effective tool against Crohn's disease and ulcerative colitis. However, it turns out, is not any kind of fiber is equally useful in these diseases.

In 2010, a study was published showing the role of broccoli and planteyna in Crohn's disease. Fiber stopped moving Escherichia coli, which causes the symptoms of Crohn's disease, the cells. When the researchers tested the effects of apples and leeks effect on bacteria was found that demanded an explanation, why did not any fiber helps in Crohn's disease.

Scientists have conducted laboratory research on cell cultures (number of broccoli or planteyna was 5 mg / ml). Moving bacteria was stopped at 45-82%. After that, they confirmed their data on tissue samples taken from patients with Crohn's disease during surgery.

Another interesting finding of the study was that the emulsifier polysorbate 60 and 80 increased the penetration of E. coli cells. The authors noted that many products which are in liquid form to patients, including through the probe to contain emulsifiers like. This explains why many patients with Crohn's disease react to liquid feeding.

Planteyn and broccoli may be a useful adjunct in the treatment of Crohn's disease, a study shows. The authors hope to develop other aspects of therapeutic diets for patients with this disease.

Volunteers chosen form visually identifying the most attractive figure of the submitted samples. Researchers recorded breast size and waist.


In the experiment was attended by 80 volunteers - girls and boys under the age of 20 years.

The study revealed that the female half of the group are interested in young people with pumped torso and shapely strong legs. But men like slim girls with big breasts.

4. Sit up straight when working at the computer, keep good posture, take breaks and get up from the chair to walk around the office.
