Contamination & food safetyHealthPolicyKnowing “Good Food”: Immigrant Knowledge and the Racial Politics of Farmworker Food Insecurity
2014Laura-Anne Minkoff-Zern · Antipode · United States
Research on farmworker food insecurity in the USA points out that food assistance providers often treat farmworkers' inability to afford healthy food as a lack of knowledge, reinforcing racialized assumptions that people of color do not know "good" food. This study argues that food security and healthy eating are not a matter of consumers making healthy "choices," but rather a matter of class-based and racial differences within the food system.
