“…We used this time frame to allow a sufficient gap in time for consumers to become familiar with the new labels and researchers to examine consumers’ familiarity with labels, which is important factor for label use (Bialkova & van Trijp, 2010). Similarly, we omit studies investigating relatively new forms of nutrition information, namely, front-of-package symbols, which appear on some products (Hawley et al, 2013; Hersey, Wohlgenant, Arsenault, Kosa, & Muth, 2013; Vyth et al, 2012). …”

The effects of nutrition knowledge on food label use. A review of the literature

2015

Nutrition information on food labels is an important source of nutrition information but is typically underutilized by consumers. This review examined whether consumer nutrition knowledge is important for communication of nutrition information through labels on packaged foods. A cognitive processing model posits that consumers with prior knowledge are more likely to use label information effectively, that is, focus on salient information, understand information, and make healthful decisions based on this information. Consistent with this model, the review found that nutrition knowledge provides support for food label use. However, nutrition knowledge measures varied widely in terms of the dimensions they included and the extensiveness of the assessment. Relatively few studies investigated knowledge effects on the use of ingredient lists and claims, compared to nutrition facts labels. We also found an overreliance on convenience samples relying on younger adults, limiting our understanding of how knowledge supports food label use in later life. Future research should 1) investigate which dimensions, or forms, of nutrition knowledge are most critical to food label use and dietary decision making and 2) determine whether increases in nutrition knowledge can promote great use of nutrition information on food labels.

“…A recent review that focused on methodological quality of simplified nutrition information research underlined the importance of objectively measuring the impact of interpretational aids on behavior change of consumers rather than only measuring improvements in understanding of nutrition information [14]. Results of the review show that studies that objectively measure longitudinal behavioral change in a realistic setting against a control measure, such as collecting sales data before and after introduction of nutrition information, were of the highest quality and relevance.…”

“…Although these methods are more effective at improving consumer understanding of food nutrient content than NFP [13], studies that actually measure their impact on behavior in realistic settings are limited and inconsistent [12,14]. Implementation of a traffic light system that color coded content of 4 nutrients (total fat, saturated fat, sodium, and sugar) in United Kingdom grocery stores showed no effect on consumer purchases [15].…”

Improvements in recall and food choices using a graphical method to deliver information of select nutrients

Consumers have difficulty using nutrition information. We hypothesized that graphically delivering information of select nutrients relative to a target would allow individuals to process information in time-constrained settings more effectively than numerical information. Objectives of the study were to determine the efficacy of the graphical method in (1) improving memory of nutrient information and (2) improving consumer purchasing behavior in a restaurant. Values of fiber and protein per calorie were 2-dimensionally plotted alongside a target box. First, a randomized cued recall experiment was conducted (n=63). Recall accuracy of nutrition information improved by up to 43% when shown graphically instead of numerically. Second, the impact of graphical nutrition signposting on diner choices was tested in a cafeteria. Saturated fat and sodium information was also presented using color coding. Nutrient content of meals (n=362) was compared between 3 signposting phases: graphical, nutrition facts panels (NFP), or no nutrition label. Graphical signposting improved nutrient content of purchases in the intended direction, whereas NFP had no effect compared with the baseline. Calories ordered from total meals, entrées, and sides were significantly less during graphical signposting than no-label and NFP periods. For total meal and entrées, protein per calorie purchased was significantly higher and saturated fat significantly lower during graphical signposting than the other phases. Graphical signposting remained a predictor of calories and protein per calorie purchased in regression modeling. These findings demonstrate that graphically presenting nutrition information makes that information more available for decision making and influences behavior change in a realistic setting.

“…These methodological issues severely limit the possibility to extend these results to population level. A recent work from Vyth and colleagues [31] highlighted the urgent need in nutrition science of longitudinal, randomized, controlled design in a real-life setting.…”

Obesity has become, nowadays, a global concern affecting both developed and developing countries. Nutrition and physical activity represent the major factors influencing energy balance and subsequently weight status. Deciding toward an appropriate intake of all nutrients is seen as necessary to maintain a wholesome lifestyle: among nutrients, sugar plays a major role and its consumption has long been seen as an issue in public health, due to its possible role in displacing or diluting nutrients in the diet and contributing to the epidemic of obesity.A research on Pubmed was assessed to evaluate the impact of confectionery consumption, as sugar source, on the daily energy intake. The studies considered in the current paper generally failed to show that confectionery consumption leads necessarily to a shift of energy intake. Anyway, considering that till now, very few works on this topic were conducted, more researches are necessary to demonstrate the effective influence of confectionery on daily energy intake.
