For a long time we have known that we could not live without the trillions of bacteria we have in our gut, as they are responsible for essential physiological functions, but in recent decades the scientific community has taken a step further and has linked this intestinal microbiota with the brain. For example, studies have discovered that people with neurodegenerative diseases such as Alzheimer's or Parkinson's have alterations in the composition of intestinal bacteria, although it is not yet known whether it is a cause or consequence of the disease. Now researchers at University College of London have discovered in a study that the microbiota can reveal if a person has a high risk of developing Parkinson's disease before symptoms appear.

The first public fecal microbiota bank in the country has been established in Catalonia. The Department of Health launched it this Wednesday to treat patients with recurrent infections caused by a bacteria called Clostridioides difficile, This disease causes severe intestinal damage that, in some cases, can be life-threatening. In these cases, those affected require a fecal microbiota transplant for recovery. In 90% of cases, it is achieved without relapse. This intervention is now part of the public health portfolio, benefiting around 200 people each year. Therefore, the department is calling on the public to find "committed" stool donors to treat these people who have no therapeutic alternative to transplants.

In the latest edition of the Ultra Pirineu mountain race, more than 1,300 runners gathered in the Cadí mountain range to cover more than 100 km of distance and 6,600 meters of elevation gain. Extremely demanding events like this make us question the limits of the human body, as well as the role that physiology, nutrition, and rest play in achieving good athletic performance and, in general, enjoying a healthy life.

There are times when we feel more tired, moody and stressed. And, as if that weren't enough, we also start to notice discomfort in the stomach, such as bloating or more gas than usual. When this happens, nutritionists are clear: our intestinal microbiota is going through a bad time and it must be remedied with changes in diet.
