Seafood Abundance Correlates With Nitrogen Stable Isotope Ratio in Japanese Diet
Key Points
This research aims to explore the relationship between seafood abundance and nitrogen stable isotope ratios in diet analysis.
Analyzed biological samples for nitrogen stable isotopes
Measured seafood abundance in the Japanese diet
Conducted correlation analysis for dietary reconstruction
Found a significant positive correlation between seafood abundance and δ15N
Implications suggest δ15N is useful for dietary reconstruction in nutritional research
Abstract
The highly significant positive correlation between the abundance of seafood and δ15N supports the utility of δ15N of biological samples for isotopic diet reconstruction/nutritional research.
