Dietary analysis based on stable isotope tracers have been developed as a technique analyzing for food consumption patterns of human and animals. The advantage of isotope analysis is not only useful to estimate consumption rate of food resources, but also be a scientific method to shed light on feeding process which composed of biological and sociological phenomenon including statistic researches. This article addresses a new direction of isotopic dietary studies from three complementary case studies.

Key words: carbon-13; nitrogen-15; dietary analysis; food consumption statistics; feeding pattern
