Exercise does not reduce the risk of multiple sclerosisexercise-does-not-reduce-the-risk-of-multiple-sclerosis

Some research theories say that physical activity reduces the risk of developing multiple sclerosis. The new analysis, however, gives to the understanding that the exercises are not a preventive measure for the disease.

According to the survey, even 2.3 million people around the world have multiple sclerosis – a disease that affects the brain and spinal cord. The disease is manifested by the difficulties in moving the limbs, disorders of vision and problems with balance and feeling. Although there is no cure for multiple sclerosis, researchers found that people with mild to moderate disability movement can reduce the risk of certain symptoms, increasing muscle strength and aerobic capacity, and improve mood. Unfortunately, according to the latest findings, physical activity does not necessarily help delay the progression of the disease.

A study of 193,000 women who are diagnosed with multiple sclerosis, showed that their activity before and after diagnosis did not affect in any way the progress of the disease. Physical activity helps maintain efficiency for longer, however, does not protect against the risk of illness.

As indicated in its most recent analysis, morning sickness, turn out to have a protective effect on the unborn child. Despite their unpleasant character, they seem to be a positive component of a healthy pregnancy.

Morning sickness – a very common sign of early pregnancy, as shown by the discovery is a good symptom! The cause of the morning problems (often occurring also during the day) results from fluctuations in estrogen, progesterone, and human chorionic gonadotropin. As theories say, they are also a kind of defense mechanism that discourages women to eat foods that may pose a risk to the fetus, during the period they are most vulnerable to toxins. The research team verified the connection of morning sickness with the maintenance of a healthy pregnancy, studying a group of 797 pregnant women. A total of 188 pregnancies ended in a loss, over 57% of women reported morning sickness, and 26.6% experienced nausea and vomiting. Analysis of the data showed that 50-75% of women experiencing morning sickness were less susceptible to loss of pregnancy compared to the women who did not feel any symptoms. One thing is sure – nausea is a sign of a healthy pregnancy!

Manuka honey may help to prevent urinary tract infectionsmanuka-honey-may-help-to-prevent-urinary-tract-infections

Manuka honey is famous for its numerous features, including in particular those antibacterial and anti-inflammatory. New studies have provided further evidence of its excellent effects, because as it turns out, it can prevent the development of bacterial biofilms – groups of microorganisms, which can stick to the surface facilitate the transfer of infection.

Based on this discovery, the researchers show that manuka honey can help in urinary tract infections. The research of honey has proven its ability for the disposal of Escherichia coli, Proteus mirabilis and other bacteria responsible for urinary tract infections, which can occur under long-term use of a catheter. Tests have shown that the bacteria lost their “stickiness” of up to 77% using Manuka honey (other honey showed the capacity to 35%). For now, the study is based only on lab tests, but perhaps in the future, they will help prevent infections in patients.

diet-rich-in-zinc-increases-the-risk-of-intestinal-infectionDiet rich in zinc increases the risk of intestinal infection

Diet containing a high concentration of zinc can increase the risk of Clostridium difficult – the type of microorganisms that cause pseudomembranous colitis, especially in people who take antibiotics.


Scientists say that individuals with high risk of infection C. difficile should be extremely careful using zinc supplements and a diet rich in products with a high content of this ingredient because of the significant amount of it, can change intestinal microflora. Thus it becomes more susceptible to infections. C. difficile is a very dangerous type of microorganisms, as it can even lead to death due to infection. Zinc, although it is an essential trace mineral, which positively affects the immune system, cell growth and division and wound healing, in excess, it can increase the risk of infectious diseases.

A study on mice showed that an excess of zinc in the diet changes the structure of microbiome in a way that increases the susceptibility to C. difficile, allowing enhanced replication of the organism and increased activity of toxins.
