8.4.2 Dietary diversity score
Dietary diversity (DD) has long been recognised as a key element of food security. It is usually measured by summing up the number of foods or food groups consumed over a period of time. Consumption of a more diversified diet is an indicator that the household is food secure; while a less diversified diet is an indicator of food insecurity. You looked at how to measure dietary diversity in Study Session 5 of this Module.
What is the relationship between food insecurity and dietary diversity?
Food insecurity leads to consumption of less diversified diet and therefore, a lack of dietary diversity is a measure of food insecurity.
