Our platform is now trilingual!

Coinciding with the second anniversary of the launch of our platform, Gut Microbiota Worldwatch, we are happy to announce that it is now available in three languages: English, French and Spanish. Together with its social networks, namely Facebook and Twitter, they form the leading international online information ecosystem devoted to gut microbiota and health for a non-specialized audience,

Edited by the Gut Microbiota & Health Section of the European Society of Neurogastroenterology and Motility (ESNM), Gut Microbiota Worldwatch aims to inform readers in a clear and accessible way about the latest developments in the field of gut microbiota, raising awareness about its importance for overall health and quality of life.

Can modified gut bacteria solve the obesity problem?

According to the World Health Organisation, obesity worldwide has nearly doubled since 1980. Every year, this condition kills 3.4 million people, a number that rises every day. Doctors and governments try to combat this epidemic using public awareness campaigns encouraging citizens to stay active and follow a healthy, low-fat diet. While it is not enough, it raises the question what if, like in the story about the Trojan horse, the problem could be tackled from the inside?

Scientists have recently become more aware of the important role the hundreds of trillions of gut microbes play in keeping us healthy. It has been discovered that this vast and diverse bacterial ecosystem, our gut microbiota, work together and collaborate in the regulation of the digestive and immune system.

“The types of bacteria you have in your gut influence your risk for chronic diseases. We wondered if we could manipulate the gut microbiota in a way that would promote health,” explains Sean Davies, assistant professor of pharmacology at Vanderbilt University. In order to answer that question, he led a study with rodents aimed at learning if genetically modified gut bacteria can play a role and produce a positive effect on health (at least, in mice).

Could gut bacteria be linked to eating disorders?

Most of us sometimes try to calm our nerves by binge-eating. When it is occasional, it may lead to some extra weight or guilty feelings. When it is a regular habit, however, it is clinically considered an eating disorder. In fact, more than 8% of the population experiences some kind of eating disorder at some point in their lives (US data). And, unfortunately, around 5% of women and 2% of men are affected by serious conditions, such as anorexia, bulimia or binge eating disorder (especially teenagers and young adults).

Until now, research in this field had been focused on the brain and the cognitive causes of these disorders. Now, a French team of scientists has shed some more light on the issue: What if the intestine and, specifically, the gut microbiota could also play a role?

In a study just published in the journal Translational Psychiatry, researchers from the French National Research Institute (INSERM – Institut national de la santé et de la recherche médicale) and the University of Rouen claimed to have discovered some bacteria in the gut that may interfere with the way the body regulates effectively appetite, at least in rodents.  Read more

Some gut bacteria may help reinforce the digestive barrier and reduce food allergies

Some time ago, it was a common practice in some countries to bring candy and cakes to celebrate birthdays at school with friends and classmates, and there was no problem. Everyone ate and enjoyed the food, and went home happy with chocolate stains all over their clothes. A generation or two after, that has become an unthinkable tradition for kids. The reason: the recent rise of food allergies.

According to Allergy UK, rates of allergy are rising all over the world, affecting 30 to 35% of people at some stage of their lives. Initially, asthma and allergic rhinitis were the most common problems; but recent studies have shown a significant increase in the incidence of food allergies, especially among infants. In fact, since 1997 there has been an estimated 50% more children suffering from food allergies. The reasons explaining this rise are not clearly known, although some previous studies have hinted that our 21st century lifestyle and diet may play a role.

Cathryn Nagler is a Professor at the University of Chicago, in Illinois. For years, she has been studying whether there is a link between the immune system, the intestinal bacteria and the onset of allergies. In 2004, she found that wiping out gut microbiota in mice led to the onset of food allergies. She has now gone one step further.  Read more
