Sources of variability in dietary intake in two distinct regions of rural India: implications for nutrition study design and interpretation

Objective: Limited inter-person variability in nutrient intake hampers epidemiologic studies of diet–disease relationships. Despite conjecture about non-traditional study bases providing large inter-person differences, virtually nothing is known about variations in nutrient intake outside of Europe and North America. The current study was conducted in India to determine sources of variability in the intakes of nutrients thought to be of public...
