The extent consumption of wheat in the diet of the past populations in China has been in-creasingly discussed and debated in recent years.Based on archaeobotanical evidences and historical records,here we review the stable carbon and nitrogen isotopic data of the past populations in the Yellow River valley from c.4000 BP to the Han Dynasties(202 BC-220 AD),focusing on the temporal-spatial consumption of wheat in human dietary pattern.Results show that wheat had been consumed in the Hexi Corridor from c.4000 BP to 3800 BP.And wheat had been consumed in the Hehuang and its contiguous region during 3600 BP.However,wheat had not been consumed abundantly in the Central Plain until the Eastern Zhou Dynasty.Concretely speaking,the dietary pattern with gradient wheat consumption for the most humans in the Guan-zhong area,Middle Shaanxi were presented during the Han Dynasties.And a similar dietary pattern was also appeared in Shanxi and Henan from the Eastern Zhou Dynasty to the Han Dynasties.Obviously,the period from the Eastern Zhou Dynasty to the Han Dynasties is a turning point for the expansion of wheat in the Yel-low River valley,which might relate to reasons of the emergence of winter wheat and the rotary mill,the car-ryout of new agricultural policies,and the population explosion.However,the related questions about wheat in central-south of Inner Mongolia,and Shandong should be researched further.In the future,we should still focus on the questions of distinguishing the extent of wheat consumption in human dietary pattern accurately.
