Abstract
Background/objectivesWe aimed to quantify the contribution of food reformulation to changes in the nutritional quality of consumers’ food purchases, and compare it with the impact of substitutions made by consumers.Subjects/methodsUsing a brand-specific data set in France, we considered the changes in the nutrient content of food products in four food sectors over a 3-year period. These data were matched with data on consumers’ purchases to estimate the change in the nutritional quality of consumers’ purchases. This change was divided into three components: the reformulation of food products, the launching of new products and the consumers’ substitutions between products. Key nutrients were selected for each food group: breakfast cereals (sugar, fats, SFA, fiber, and sodium), biscuits and cakes (sugar, fats, SFA, and fiber), potato chips (fats, SFA, and sodium) and soft drinks (sugar).ResultsProduct reformulation initiatives have improved existing products for most food group-nutrient pairs. In particular, the contribution of food reformulation to the change in nutritional quality of food purchases was strong in potato chips (the sales-weighted mean SFA and sodium contents decreased by 31.4% to 52.1% and 6.7% to 11.1%, respectively), and breakfast cereals (the sales-weighted mean sodium content decreased by 7.3% to 9.7%). Regarding the launching of new products, the results were ambiguous. Consumers’ substitutions between food items were not generally associated to an improvement in the nutritional quality of the food purchases.ConclusionsPolicies aiming to promote food reformulation may have greater impact than those promoting changes in consumer behavior.
