Impacts of elevated atmospheric CO2 on nutrient content of important food crops (original) (raw)

AI-generated Abstract

This paper presents a comprehensive metaanalysis investigating the impact of elevated atmospheric CO2 on the nutritional content of key food crops, primarily utilizing free-air CO2 enrichment (FACE) technology. The study synthesizes data from 41 cultivars across six major crop species, revealing significant alterations in macro- and micronutrient concentrations linked to increased CO2 levels, which implies potential public health implications for populations dependent on these staple crops. The findings highlight the need for future research to assess how these changes may affect global nutrition and health.
