| 研究実績の概要 |
I have collected and analyzed the following databases required for conducting this research. (1) worldwide nutrient (micronutrient) supply database; (2) food supply database; (3) food consumption/intake database; (4) food composition table; (5) nutrient density decrease under high CO2 concentration; (6) disease burden of nutrient deficiency.
Based on these databases, I analyzed the impact of high CO2 concentration (550 ppm in 2050) on nutrient deficiency of Chinese adult population. Protein, iron, and zinc intake were found to reduce by 2.17-4.75% and the prevalence of deficiency would increase by 1.35-4.42%. It also revealed a significant disparity among income groups: nutrient loss rates for the lowest-income group were 1.37-1.54 times greater than the highest-income group.
