Context: It is well established in the literature that healthier diets cost more than unhealthy diets. Objective: The aim of this review was to examine the contribution of food prices and diet cost to socioeconomic inequalities in diet quality. Data Sources: A systematic literature search of the PubMed, Google Scholar, and Web of Science databases was performed. Study Selection: Publications linking food prices, dietary quality, and socioeconomic status were selected. Data Extraction: Where possible, review conclusions were illustrated using a French national database of commonly consumed foods and their mean retail prices. Data Synthesis: Foods of lower nutritional value and lower-quality diets generally cost less per calorie and tended to be selected by groups of lower socioeconomic status. A number of nutrient-dense foods were available at low cost but were not always palatable or culturally acceptable to the low-income consumer. Acceptable healthier diets were uniformly associated with higher costs. Food budgets in poverty were insufficient to ensure optimum diets. Conclusions: Socioeconomic disparities in diet quality may be explained by the higher cost of healthy diets. Identifying food patterns that are nutrient rich, affordable, and appealing should be a priority to fight social inequalities in nutrition and health.

“…The DANTE diet cost database was evaluated using a comparison of diet cost from till receipt collection and from a 4-day food diary with costs assigned by the database showing that at a population level, the difference was as little as £0.02, which is less than 1% of the mean daily diet cost 21. The costs in this study are also assigned at an individual level and averaged for the dietary patterns further increasing reliability of the dietary pattern costs.…”

“…The dietary patterns reflect quantity and diversity of food and have been assigned a healthiness score according to how well they adhere to the Department of Health's Eatwell Plate. Diet cost is assigned from a food cost database, which has been evaluated and deemed suitable for population research 21. The main aim is to show whether there are any differences in cost between a healthy dietary pattern in UK women and a less healthy pattern.…”

Healthy 18 Dietary pattern 19 Diet cost 20 UK W C Study 21 22Word count = 3028 23 ABSTRACT: 24 Background: 25A healthy diet is important to promote health and wellbeing whilst preventing chronic disease. 26However, the monetary cost of consuming such a diet can be a perceived barrier. This study will 27 investigate the cost of consuming a range of dietary patterns. 28 Methods: 29A cross sectional analysis, where cost of diet was assigned to dietary intakes recorded using a Food 30Frequency Questionnaire. A mean daily diet cost was calculated for seven data driven dietary 31 patterns. These dietary patterns were given a healthiness score according to how well they comply 32 with the UK Department of Health's Eatwell Plate guidelines. This study involved ~35000 women 33 recruited in the 1990s into the UK Women's Cohort Study. 34 Results: 35A significant positive association was observed between diet cost and healthiness of the diet (p for 36 trend >0.001). The healthiest dietary pattern was double the price of the least healthy, £6.63/day and 37 £3.29/day respectively. Dietary diversity, described by the patterns, was also shown to be associated 38

“…This study lacked information on participants’ actual food spending and the origin of foods consumed, which could have resulted in misclassification of dietary cost. However, dietary costs (as derived with reported dietary intakes and a fixed database of food prices) are modestly but positively correlated with actual food spending,31, 32, 33 therefore, being suitable for our purpose of ranking individuals into tertiles of dietary cost. There was no information on the actual shopping location of the participants.…”

“…This measure of dietary cost is positively correlated with actual food expenditures, which has been described in detail elsewhere 31, 32, 33. Briefly, retail prices for each of the foods in the FFQ were obtained from five major UK supermarket chains in 2012, which together had a majority market share in that year 34 .…”

IntroductionIt is unknown whether there is an interplay of affordability (economic accessibility) and proximity (geographic accessibility) of supermarkets in relation to having a Dietary Approaches to Stop Hypertension (DASH)-accordant diet.MethodsData (collected: 2005–2015, analyzed: 2016) were from the cross-sectional, population-based Fenland Study cohort: 9,274 adults aged 29–64 years, living in Cambridgeshire, United Kingdom. Dietary quality was evaluated using an index of DASH dietary accordance, based on recorded consumption of foods and beverages in a validated 130-item, semi-quantitative food frequency questionnaire. DASH accordance was defined as a DASH score in the top quintile. Dietary costs (£/day) were estimated by attributing a food price variable to the foods consumed according to the questionnaire. Individuals were classified as having low-, medium-, or high-cost diets. Supermarket affordability was determined based on the cost of a 101-item market basket. Distances between home address to the nearest supermarket (geographic accessibility) and nearest economically-appropriate supermarket (economic accessibility) were divided into tertiles.ResultsHigher-cost diets were more likely to be DASH-accordant. After adjustment for key demographics and exposure to other food outlets, individuals with lowest economic accessibility to supermarkets had lower odds of being DASH-accordant (OR=0.59, 95% CI=0.52, 0.68) than individuals with greatest economic accessibility. This association was stronger than with geographic accessibility alone (OR=0.85, 95% CI=0.74, 0.98).ConclusionsResults suggest that geographic and economic access to food should be taken into account when considering approaches to promote adherence to healthy diets for the prevention of cardiovascular diseases and other chronic disease.
