Caste-based inequality in fruit and vegetables consumption in India

Objective:

Fruit and vegetable (F&V) consumption is of central importance to many diet-related health outcomes. In India, caste is a major basis of socioeconomic inequality. Recent analysis shows that more disadvantaged “lower” castes consume less F&V than the rest. This article explores whether this consumption gap arises due to differential distribution of drivers of consumption such as income and education across castes, or whether behavioral differences or discrimination may be at play.

Design:

The Oaxaca-Blinder regression decomposition is applied to explain the gap in F&V consumption between “upper” castes and “lower” castes, using data from the 68th (2011-2012) round of the National Sample Survey Organization household survey.

Results:

Differences in the distribution of F&V drivers account for all of the 50 grams/person/day consumption gap between upper and lower castes. In particular, much of the gap is explained by income differential across castes.

Conclusions:

In the long run, India’s positive discrimination policies in education and employment that seek to equalize income across castes are also likely to help close the F&V consumption gap, leading to health benefits. In the medium run, interventions acting to boost lower caste income, such as cash transfers targeting lower castes, may be effective.
