This week on health news:
Research conducted by scientists from Australia have shown that the gradual increase in muscle strength, through activities such as weight lifting, can improve cognitive functions, especially in seniors.
This finding is of particular importance because of the increasing incidence of dementia and Alzheimer’s disease in an aging population. According to flash estimates, even 47 million people worldwide have dementia, and this number could triple by the year 2050. Disciplined schedule of strength training can, therefore, be an excellent way to improve cognitive function, and thus to strengthen the power of the brain. According to this, which results from studies, the relationship between improving brain function and improving muscle strength is proportional. Therefore it is worth to keep fit by training muscles at least twice a week so that you can achieve maximum benefits for the brain.
According to new research, evolutionary balance of fats, restored in the daily diet can help prevent obesity. Many organizations and scientists believe that the problem of obesity may affect up to 600 million people around the world, and all this may be related to an imbalance between energy intake and its expenditure.
Studies suggest that to prevent and reduce obesity in the global population, it is essential to balancing the omega-6 and omega-3. The principles of nutrition, which were focused on the fact that all calories are equal to each other failed the test, especially that evolution induces many changes. This internal balance of fatty acids in the body thus becomes crucial, and the providing of equal amounts of omega-3 and omega 6 (in which the food is intensively enriched) should be leveled, as they are metabolized differently. The main idea is to reduce the amounts of omega – 6 of which food contains far too much.
Alcohol consumption – especially in excess, is most often associated with men, but as the result of recent studies, women are catching up with men in this disgraceful habit. This means that women are more likely to suffer the same adverse effects of alcohol.
Alcohol is one of the most important risk factors for diseases on a global scale, along with smoking, environmental pollution, and hypertension. Alcohol abuse causes an average of 5% of deaths worldwide. It is also concerned that women more often suffer from alcohol diseases, which, alcoholism ceases to be equated with men. The study does not explain from where comes from this drastic change but probably is due to the equalization of gender roles.
Triple-negative breast cancer is an aggressive disease that poses a significant clinical challenge. Biology of the disease is significantly less understandable, as compared with many other existing forms of cancer, making it tough to treat. But, as recent findings suggest, screening a prolactin receptor may be a breakthrough in treating of this type cancer.
The researchers found that triple-negative cancer cells without a prolactin receptor are not only more aggressive but also rapidly dividing and are more invasive. This kind of tumor occurs in about 15% of breast cancer cases, and it is unfortunately associated with a high relapse rate and most frequently poor prognosis. According to the researchers, prolactin may help reduce the ability of cancer cells to divide and prevents the formation of new tumors, making cancer less aggressive. If the study goes in the right direction as so far, the hormone of prolactin may become a salvation for patients.
