Health Shock Effects on Diet: More Severe Shock-Stronger Response?

Abstract

We investigate whether the severity of lifestyle-related health shocks affects the response in dietary patterns. Using data from official patient registers in Denmark, we analyze the effects from strong health shock (SHS) occurrences (cardiovascular disease) and mild health shock (MHS) occurrences (arterial hypertension and hypercholesterolemia). These data are combined with scanner data on food purchases obtained from a consumer panel. Our analysis examines dietary effects stemming from these health shocks, including various nutrients, food groups, and overall adherence to dietary guidelines. Our findings reveal immediate dietary responses to both severe and mild health shocks, with a larger effect observed for SHS compared to MHS. However, among individuals previously exposed to mild health shocks, we observe minimal to no alteration in food consumption after experiencing a SHS. We argue that failing to account for this potential self-selection may lead to a misconception that severe health shocks do not result in dietary improvements.
