Consumption of food additives during pregnancy: effects on offspring microbiota increase susceptibility to inflammatory diseases

These microbiota alterations are thought to significantly increase their risk of developing chronic inflammatory gut disorders and obesity in adulthood. The harmful transgenerational effects of maternal consumption of emulsifiers on the health of offspring highlight the need for additional research in humans on the impact of direct exposure to emulsifiers during early childhood. These findings were published in the journal Nature Communications.
