Dietary quality as a non-medical health input: a theoretical approach to analyse the demand for dietary quality
构建了一个理论模型，将膳食选择视为健康投资，考虑健康与口味的跨期权衡，并通过模拟复现实证研究中的膳食质量模式，为食品与营养政策提供因果路径理解。
The aim of this inquiry is to provide a comprehensive theoretical framework, which describes the demand for dietary quality. In our dietary health investment model, we consider the health investment character of dietary choices as well as the intertemporal health-taste trade-off. Additionally, a simulation model is presented to illustrate the model's empirical application as well as its capability to replicate the patterns of dietary quality found in other empirical studies. As a result, our model setting can aid food and nutrition policy through an increased understanding of the responsible causal pathways behind the increasing prevalence of diet-related chronic diseases.
