Receipt of food stamps is often observed to be positively correlated with intake of nutrients. However, this observed fact could be the result of self‐selection into the food stamp program by those individuals who are more interested in maintaining good nutrition. We observe that, controlling for participation in the food stamp program, nutrition is negatively affected by food stamp income for a sample of elderly people. However, we find that the levels of nutrients do not decrease enough to cause individuals to fall below the Recommended Dietary Allowance.
