Association Between Sex Inequality in Animal Protein Intake and Economic Development in the Papua New Guinea Highlands: The Carbon and Nitrogen Isotopic Composition of Scalp Hair and Fingernail

摘要

Objectives: People in the Papua New Guinea Highlands consume sweet potatoes as their dietary staple; consumption of animal protein is limited. In such societies with marginal protein intake, the intra-household allocation of animal protein in terms of sex or age is of importance. The objective of this study was to investigate how the allocation pattern of protein-rich foods by sex and age is associated with economic development in the Papua New Guinea Highlands.
