Does a nutritious diet cost more in food deserts?

Food deserts and their potential effects on diet and nutrition have received much attention from policymakers. While some research has found a correlation between food deserts and consumer outcomes, it is unclear whether food deserts truly affect consumer choices. In this article, we compare food prices in food deserts, defined as low‐income, low‐access census tracts, and nonfood deserts to observe whether and to what extent consumers face higher prices for a complete diet in food deserts. If a nutritionally complete diet costs significantly more in food deserts, resident consumers may be constrained from consuming healthier foods. We use store‐level scanner data from a nationally representative sample and calculate a census‐tract level Exact Price Index (EPI) based on a food basket defined by the Thrifty Food Plan (TFP). The EPI addresses potential biases from both product heterogeneity and variety availability. We find that the overall price impact of living in a food desert is small; low‐access areas have only 3.5% higher EPI than high‐access counterparts. However, consumers who are constrained to shop within their own census tracts face a much higher EPI than high‐access counterparts (9.2%). The higher EPI primarily comes from lower variety availability in food deserts.     

Fruit and Vegetable Consumption Patterns: A Segmentation Approach

In this article, we study the heterogeneity of fruit and vegetable consumption patterns in France. A finite mixture of AIDS models is used to describe food demand patterns revealing different preferences over distinct classes. We obtained six different clusters, which reflect specific socio-demographic characteristics and different income and price elasticities. This approach is appropriate for targeting specific public nutritional policies. Our main results show that unlike the other clusters in which the usual price and income policy tools may be used, the lowest income cluster with the lowest consumption, remains insensitive to economic variables.     

Food security,obesity, and inequality: Measuring the risk of exposure to the neoliberal diet

In reviewing the so‐called obesity “epidemic”, we critique the individual‐focused explanations that also lead to interventions at this level. Instead, we suggest a different possibility: that food choices are structurally conditioned by income inequality, first; and, second, that we eat what huge oligopolistic food producers and distributors have on offer, which is in turn shaped or facilitated by neoliberal state intervention. To highlight the relevance of structural factors, we develop an index that measures the risk of exposure to what we call the “neoliberal diet” for low‐to‐middle‐income working classes. Using this index, we compare the United States and Canada, advanced capitalist countries that are also agro‐export powerhouses, with a group of countries including the BRICs (Brazil, Russia, India, and China) plus Indonesia, Mexico, South Africa, and Turkey. We conclude that state interventions need to refocus on reducing social inequality and the social determinants of food production and distribution. Transcending individualistic and consumption approaches will help us appreciate that the state, not the individual consumer, is best positioned to implement change when it comes to food “choices” and food production.

中国人饮食方式演变研究

有文字记载以来,中国人饮食方式经历了分餐、聚餐、合餐的演变,从先秦到宋代,横跨3000余年。先秦至汉魏六朝,因《礼》制束缚和客观物质制约,人们饮食方式为分餐制;进入唐、宋兴盛时期,在文人参与带动下,宴饮的盛行和宴饮文学繁荣,以及向商业化发展,人们相聚而（饮）食,久而久之合餐成为必然。
