• Long-term trends in grain yield and main nutrient contents of three staple cereal crops in China (1980–2024) (2026) · Frontiers in Nutrition · doi

  Harvest year accounted for only a limited proportion of the variation in grain protein concentration. The study did not fully explain the variation in dietary fiber concentration. The study relied on data from publicly available food composition databases and published literature databases.

• Long-term trends in grain yield and main nutrient contents of three staple cereal crops in China (1980–2024) (2026) · Frontiers in Nutrition · doi

  Further research is needed to understand the drivers of long-term changes in grain nutrient composition. Studies should investigate the effects of genetic improvement, agricultural management, and environmental changes on grain nutrient concentrations. Research should focus on developing strategies to improve grain nutrient concentrations while maintaining high yields.
