Women need to sleep longer than men, due to lack of sleep as they develop depression, according to U.S. scientists. This is the conclusion the staff at Duke University in North Carolina, who found that the fairer sex, suffering from deprivation (a mental condition caused by the deprivation of the most basic necessities of life) sleep, often faced with depression and behave more aggressively. At the same time, according to the researchers, the lack of sleep does not cause such problems in men. Scientists explain this fact is that the brain of women requires a longer recovery time. Earlier it was reported that the lack of sleep in women may increase the risk of cardiovascular diseases, diabetes and other diseases. Swiss scientists with previously expressed the opposite view, arguing that insomnia can help in the treatment of depression.

Caffeine improves memory

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, researche

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 i

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 penetra
