Toronto, March 2 (NationPress) A group of scientists has discovered small molecules in the bloodstream that may significantly affect early childhood development.
The team from McMaster University illustrates how dietary influences, early life experiences, and gut health can shape a child's growth and cognitive achievements.
In collaboration with Brazilian researchers, they conducted an untargeted metabolomic analysis on blood samples from over 5,000 children aged six months to five years as part of Brazil's National Survey of Child Nutrition.
The analysis revealed a number of metabolites—small molecules formed through human metabolism and microbial fermentation, referred to as uremic toxins—that were negatively correlated with developmental outcomes.
These metabolites are crucial for human health, particularly during early life stages.
“Our research uncovers the intricate links between diet, gut health, and a child's developmental trajectory,” said Philip Britz-McKibbin, a professor in the Department of Chemistry and Chemical Biology.
By pinpointing specific metabolites associated with a child's overall development, we can better comprehend how potentially changeable risk factors might promote optimal growth and cognitive advancement, he noted in the study published in the journal eLife.
The researchers concentrated on metabolites found in the bloodstream that correlated with early cognitive development stages, utilizing a metric called the Developmental Quotient (DQ).
The World Health Organization employs this metric to assess whether children are achieving age-appropriate social and cognitive milestones.
This methodology led to the discovery of various bioactive metabolites commonly linked to chronic kidney disease, suggesting that even slight increases in their levels could lead to inflammation and developmental setbacks during early childhood.
“Interestingly, many of these metabolites are associated with the gut-brain axis, indicating that a healthy gut microbiome could be crucial for a child's cognitive and social development,” explained Britz-McKibbin.
The implications of these findings could be extensive, paving the way for early detection and intervention for children at risk of developmental delays.
They could also enhance public health policies and early childhood development initiatives, highlighting the significance of maternal nutrition, dietary quality, and breastfeeding practices.
