“…Warming up industrially processed dishes incurred a lower energy cost than cooking home-prepared dishes (mean additional cost of 0•07 € (SD 0•08) v. 0•32 € (SD 0•36), respectively). When adding the energy cost to the purchase cost, industrially processed dishes still cost on average 0•60 €/4p more than their home-prepared counterparts (3…”

AbstractObjective:To cope with the pressure of modern life, consumer demand for convenience foods has increased in the last decades. The current study set out to compare the costs of buying industrially processed dishes and of preparing them at home.Design:Direct purchase costs of industrially processed dishes frequently consumed in France (n 19) and of the ingredients needed for their home-prepared counterparts (n 86) were collected from four major food retailers’ websites in Montpellier, France. Mean prices and energy density were calculated for four portions. Costs related to energy used by cooking appliances and time spent preparing dishes were further estimated.Setting:Montpellier, France.Participants:Not applicable.Results:Based on the costs of ingredients and energy used for cooking, dishes prepared at home cost less (–0·60 € per four portions, P < 0.001) than industrially processed dishes, but when the cost of time was taken into account, the industrially processed dishes were much cheaper (–5·34 € per four portions, P < 0.001) than their home-prepared counterparts. There was no difference in energy density between industrially processed and home-prepared dishes.Conclusions:Our findings suggest that industrially processed dishes are more profitable to consumers when the cost of time for preparing dishes at home is valued. Given the ever greater demands of everyday life, more account should be taken of the additional cost to consumers of the time they spend preparing meals at home.

“…Similar commercial food purchase and sales data have been increasingly used in academic research to measure dietary patterns, estimate nutritional intake, model disease outcomes and evaluate policies, and they are generally considered a good indicator of diets (Bandy et al, 2019). Recent studies, for example, that have used Kantar Worldpanel data on food purchases include, Caillavet et al (2018) who analysed trends of food purchases of French households and Cornelsen et al (2019) who used the UK household panel to analyse demand for take-home food purchases.…”

HighlightsUnique dataset allows analysis of urban Indian shopping habits of processed foods.Beyond staples, purchases of processed foods and beverages for home use are low.Fastest rate of growth seen in sweet and salty snacks, and edible oil purchases.Highest volume of processed foods and beverages purchased by Delhi population.Large variations across states in level and trends of purchases over time.

“…Five papers looked at trends in nutrient composition of foods over time. Two of these used Kantar data to track the nutritional content of foods in France, with one finding that the sales-weighted sodium content of potato chips and breakfast cereals had fallen by 6.7–11.1% and 7.3–9.7% respectively from 2008 to 2011 [30] and another finding that the energy density of foods overall had increased, but that total caloric purchases had fallen by 6.7% over 1969–2010 despite the energy density of foods increasing, overall purchase of energy had fallen by 6.7% [31]. Two studies conducted in the US analysed the nutritional quality of food purchases based on store-type.…”

The use of commercial food purchase data for public health nutrition research: A systematic review

BackgroundTraditional methods of dietary assessment have their limitations and commercial sources of food sales and purchase data are increasingly suggested as an additional source to measuring diet at the population level. However, the potential uses of food sales data are less well understood. The aim of this review is to establish how sales data on food and soft drink products from third-party companies have been used in public health nutrition research.MethodsA search of five electronic databases was conducted in February-March 2018 for studies published in peer-reviewed journals that had used food sales or purchase data from a commercial company to analyse trends and patterns in food purchases or in the nutritional composition of foods. Study quality was evaluated using the National Institutes of Health (NIH) Quality Assessment Tool for Cohort and Cross-Sectional Studies.ResultsOf 2919 papers identified in the search, 68 were included. The selected studies used sales or purchase data from four companies: Euromonitor, GfK, Kantar and Nielsen. Sales and purchase data have been used to evaluate interventions, including the impact of the saturated fat tax in Denmark, the soft drink and junk food taxes in Mexico and supplemental nutrition programmes in the USA. They have also been used to identify trends in the nutrient composition of foods over time and patterns in food purchasing, including socio-demographic variations in purchasing.ConclusionFood sales and purchase data are a valuable tool for public health nutrition researchers and their use has increased markedly in the last four years, despite the cost of access, the lack of transparency on data-collection methods and restrictions on publication. The availability of product and brand-level sales data means they are particularly useful for assessing how changes by individual food companies can impact on diet and public health.
