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.

Men, especially the elderly, can get a lot of benefits for physical and mental health if they are dieting based on meat and fish.

In a study of Japanese scientists, which lasted seven years, attended by more than 1,000 elderly men. Volunteers who "leaned" on meat and fish, thus reducing by 39 percent the risk of reducing the mental and physical functions (compared with men who did not practically eat animal protein). Unfortunately, the same trend was not seen in women.

Initially, participants were asked to give details about their diet, including the consumption of animal protein. Health status, as well as social and intellectual aspects of volunteers was recorded twice - at the beginning of the study and seven years later. The volunteers were divided into four groups, depending on how much meat and fish are eating. At the end of about a quarter of the study participants showed a decline of intellectual and other skills. Basically this sad trend was observed among those who neglected animal proteins. While men who ate more meat and fish, in contrast, showed a significant reduction in the risk of cognitive impairment, as well as the development of diseases associated with aging.

Critics of the study emphasize that the work was not taken into account the intensity of the exercise - an important factor in mental and physical health. Nevertheless, it is generally agreed that the proper intake of protein is important, especially for aged people, when the need for this nutrient may increase.

Supplementation with whey or casein in combination with physical activity is associated with significant improvements in the readings of blood pressure in young women with obesity and hypertension , according to a new study.

Scientists from the University of Florida, USA, reported that the milk protein casein supplements sports training overweight women and helps reduce aortic systolic blood pressure. In particular, taking whey and casein was associated with a reduction in brachial systolic blood pressure by 5 points, and aortic systolic blood pressure by 7 points.

Benefits of dairy products for systolic blood pressure has long been known. Thus, the use of dairy product may be an additional tool in the prevention or treatment of hypertension .

Scientists explain that the aortic blood pressure, and not brachial blood pressure is considered to be the best predictor of cardiovascular benefits of the intervention using antihypertensives.

"To our knowledge, our study is the first to demonstrate a reduction in aortic systolic blood pressure under the influence of milk proteins. Because aortic blood pressure adversely affects the function of the left ventricle to a greater extent than the brachial blood pressure, our findings may be of clinical importance ", - the scientists.

The results of the work were published in the journal American Journal of Hypertension.

Researchers at Harvard Medical School studied the effect of hot chocolate on the human brain. Researchers concluded that cocoa contained in nutrients necessary for a person as protect his brain damaged areas of education.

In particular, experts have found a link between what the consumption of hot chocolate and memory, thinking, and neurovascular coupling in the brain - a process in which blood flow to the brain tissue changes with increased activity of certain brain regions. Neuroscientists explain that Neurovascular communication plays an important role in diseases involving degeneration of the brain, for example, in the development of Alzheimer's disease .

In an experiment to study the properties of cocoa 60 elderly people without dementia, at an average age of 73 years, every day during the month of drinking a cup of hot chocolate. In this study participants did not use any more products containing chocolate.

When a month of daily use small portions of hot cocoa volunteers underwent tests on memory and thinking, experts have identified improvements in the state of their brain. If at the beginning of the study 18 of the 60 participants had weakened neurovascular relationship by the end of its research performance has improved by 8.3%.

According to experts, due to the weakened neurovascular characteristic insufficient blood flow to certain areas of the brain. The result of this defective blood flow may be the emergence in the white matter of the brain damaged areas tiny - it shows MRI studies. Based on the experimental results, the use of hot chocolate protects against unpleasant process.

More advanced participants and demonstrated ability for testing short-term memory. The same task they perform, on average, at the beginning of the experiment - for 167 seconds, after - just for 116 seconds.

Thus, the researchers were convinced that eating chocolate brings clear benefits to the human brain. However, experts note that this delicacy overeat still not worth it - just to indulge yourself sometimes dessert.
