In the given case, the anthropologist is dealing with nutritional anthropology.
Nutritional anthropology refers to the interaction between economic systems, human biology, food security, and nutritional status, and how the modifications in the former influences the latter.
If the environmental and economic modifications in a community influence access to food security, food, and dietary health, then this association amid the biology and culture is in turn associated with broader economic and historical trends related to globalization.
The nutritional status influences the entire status of health, overall potential for economic development, and the work performance potential for any given group of individuals.
