Is brushing your teeth to avoid developing Alzheimer’s disease possible?

Microbiomes celebrate among our English neighbours. Whether we are talking about intestinal or oral flora, research on the topic is increasing and shows the link that these microbes have with our health, both physical and psychological.

Treat the oral microbiome to ward off certain diseases

This is the whole topic of the last issue of the year of the English magazine New scientist, dedicated to the oral microbiome, or rather the ecosystem of bacteria, fungi and other viruses that happily thrives in our mouth. According to the magazine, whose comments are broadcast by International mail, “If our oral hygiene is poor, bad bacteria can spread throughout the body, causing or exacerbating problems ranging from cardiovascular disease to cancer, Alzheimer’s disease and arthritis. On the other hand, maintaining a good balance helps avoid decline. »

The good news, when you discover an unsuspected causal link between two things, is that you can treat the problem at the source. New scientist therefore insists on the fact that good gum hygiene is essential to limit the risk of developing certain diseases and provides a series of tips for taking care of your mucous membranes.

If you develop gum disease (which may ultimately be linked to an increased risk of cancer or Alzheimer’s disease), there are effective treatments to reverse the trend. For example, list New scientist, “deep cleaning under the gums, in which dentists use special tools to scrape plaque, tartar and bacteria from under the gums. Other possible options are antibiotics, gum surgery or the extraction of some teeth.”

As reported by the British weekly, the study of oral flora and the way in which it affects our health is rapidly expanding. This also means that many solutions and remedies are currently being studied. The idea “to swap our poor modern oral microbiome with the healthier one of ancient humans” it is part of it, it abounds International mail. In fact, our ancestors did not have the same oral hygiene problems as us.

Preserve your intestinal flora to combat social anxiety

Evidently the UK is becoming an expert on the subject as this second piece of information arrives Caretaker. According to a new study published December 26 in the journal PNAS, there is a link between microbes in the gut and the development of social anxiety disorder. People affected by this disorder do not have the same intestinal flora as others.

Scientists have already found that the gut microbiome – the collection of bacteria and other organisms that live in the gastrointestinal system – differs in people with social anxiety disorder (SAD) compared to healthy people, while a growing body of research has revealed that microbes in the gut the gut can influence the brain – and vice versa. This time, researchers found that when gut microbes from people with social anxiety were transplanted into mice, the animals responded more to social fear.

[…] The findings suggest that the gut microbiome may increase risks of social phobia for people with social anxiety disorder, and the study offers new avenues for developing treatments for people with SAD.

Among the treatments explored, specific diets based on fiber or fermented products to alter the intestinal flora of people with SAD, and therefore reduce their sensitivity to situations that can generate social phobia.

According to John Cryan, co-author of the study, interviewed by our British colleagues, “The bottom line is that we need to take care of our microbes, especially during development and even into adulthood.” Advice that applies to both the mouth and the stomach!
