Earlier this week,
@ProfSumantraRay , on behalf of
@nnedpro , contributed to a TV panel on
@trtworld , alongside multidisciplinary experts from Columbia and Bonn, examining the impact of rising COโ levels on the nutrient quality of crops and the implications for population health and global food security.

๐ญ. Rising COโ levels may act as a ๐ฏ๐ถ๐ต๐ณ๐ช๐ฆ๐ฏ๐ต ๐ฅ๐ช๐ญ๐ถ๐ต๐ฆ๐ณ, increasing sugars and starches while reducing the density of essential vitamins, minerals and protein in staple crops such as rice, wheat and pulses โ nutrients vital for immune function and cognitive development.
๐ฎ. This raises the risk of ๐ฉ๐ช๐ฅ๐ฅ๐ฆ๐ฏ ๐ฉ๐ถ๐ฏ๐จ๐ฆ๐ณ, where populations may meet caloric requirements yet remain malnourished, potentially worsening stunting, micronutrient deficiencies and metabolic disease globally.
๐ฏ. Beyond nutrient loss, elevated COโ levels may increase the uptake of heavy metals such as lead in certain crops, introducing additional and under-recognised food safety risks.
๐ฐ. These impacts are likely to disproportionately affect underserved and marginalised communities that rely heavily on staple crops, further widening global nutrition and health inequities.
๐ฑ. While research in this area remains limited, emerging longitudinal evidence is sufficient to warrant urgent, action-oriented research to inform policy, professional practice and public understanding.
As we enter the New Year, this discussion underscores the urgency of prioritising climate-sensitive nutrition research to strengthen resilience in food systems and protect population health โ particularly among the worldโs most vulnerable communities. As Professor Ray observed, climate change is no longer only a threat to how much food we produce, but increasingly to the nutritional quality and safety of the food systems that sustain population health.
