Lost of microbial diversity due to industrialization is associated to many diseases

“If microbial disruption due to urbanization increases the diseases of industrial societies, then the current global pandemics will worsen, with economic impact jeopardizing health care systems”.

Incidence of obesity, diabetes, asthma, allergies, inflammatory bowel disease and autism is still rising both in industrialized world and developing countries. The authors of this article, just published in Science magazine, believed that these health issues, which have huge economic impacts, are linked to the loss of human microbiota diversity, that is occurring concomitantly with industrialization. This change of microbiota diversity (in and on our body) involves the loss of ancestral bacteria.

Microbiome is transmitted in early life from mothers to their children and guides the development of immune, metabolic and neural systems. Studies on animals have shown that microbiome perturbations in early life are associated with later development of diseases like obesity, diabetes or asthma.  For the authors, this loss could be reversed by curtailing the overuse of antibiotics, limiting caesarian sections (only when it is necessary and not for convenience), promoting breast feeding, removing antibacterial compounds or changing diets.
