Think small: solving the global challenge of malnutrition by looking at metabolites
Dr Jonathan Swann’s research looks at thousands of small molecules called metabolites in an attempt to better understand a bigger problem of malnutrition and infection – a vicious combination.
Around the world, chronic undernutrition burdens the lives of over 150 million children. The effects of early life undernutrition can extend beyond infancy, stunting the physical and cognitive development of children. This stunting can often have wider societal effects including a decrease in the productivity and economic output of a community, restricting its overall progress. To make matters worse, chronic undernutrition is closely associated with repeated and persistent infections.
Such infections are common in resource-constrained settings due to inadequate water supplies and lack of access to basic healthcare. This double burden of malnutrition and infections can combine to drive inflammatory processes in the gut leading to malabsorption of nutrients and impaired immune responses, further exacerbating the malnourished state and persistence of infections. Breaking this cycle of undernutrition, infections and poverty represents a significant challenge.
