Sociodemographic disparities in purchases of fruit drinks with policy relevant front-of-package nutrition claims. Public Health Nutr 2023; 26:1585-1595. [PMID: 37211358 PMCID: PMC10410375 DOI: 10.1017/s1368980023000691] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 02/08/2023] [Accepted: 04/12/2023] [Indexed: 05/23/2023]
Abstract
OBJECTIVE Our objectives were to describe sociodemographic characteristics associated with the purchase of (1) any fruit drinks and (2) fruit drinks with specific front-of-package (FOP) nutrition claims. DESIGN Cross-sectional. SETTING USA. PARTICIPANTS We merged fruit drink purchasing data from 60 712 household-months from 5233 households with children 0-5 years participating in Nielsen Homescan in 2017 with nutrition claims data. We examined differences in predicted probabilities of purchasing any fruit drinks by race/ethnicity, income and education. We constructed inverse probability (IP) weights based on likelihood of purchasing any fruit drinks. We used IP-weighted multivariable logistic regression models to examine predicted probabilities of purchasing fruit drinks with specific FOP claims. RESULTS One-third of households with young children purchased any fruit drinks. Non-Hispanic (NH) Black (51·6 %), Hispanic (36·3 %), lower-income (39·3 %) and lower-educated households (40·9 %) were more likely to purchase any fruit drinks than NH White (31·3 %), higher-income (25·8 %) and higher-educated households (30·3 %) (all P < 0·001). In IP-weighted analyses, NH Black households were more likely to purchase fruit drinks with 'Natural' and fruit or fruit flavour claims (6·8 % and 3·7 %) than NH White households (4·5 % and 2·7 %) (both P < 0·01). Lower- and middle-income (15·0 % and 13·8 %) and lower- and middle-educated households (15·4 % and 14·5 %) were more likely to purchase fruit drinks with '100 % Vitamin C' claims than higher-income (10·8 %) and higher-educated households (12·9 %) (all P < 0·025). CONCLUSIONS We found a higher likelihood of fruit drink purchases in lower-income, lower-educated, NH Black and Hispanic households. Experimental studies should determine if nutrition claims may be contributing to disparities in fruit drink consumption.

Nutritional quality of prepackaged foods carrying health or nutritional claims in KSA. J Taibah Univ Med Sci 2022; 18:587-594. [PMID: 36818170 PMCID: PMC9906008 DOI: 10.1016/j.jtumed.2022.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Revised: 11/06/2022] [Accepted: 12/03/2022] [Indexed: 12/23/2022] Open
Abstract
Objectives To evaluate the nutritional quality of products carrying health or nutritional claims to protect consumers from being misled and to ensure that they are provided with accurate information about food products that are associated with health or nutritional claims. Methods This was a cross-sectional survey of 1153 foods that were randomly sampled from 14 stores in Riyadh, KSA. The data were collected from nutritional facts presented on food labels and evaluated by comparing the mean level of nutrients between products that featured claims and those that did not use the UK nutrient profile model (UKNPM). Results Overall, 29% of products carried either health or nutritional claims. Only 19.2% of foods that carried health claims met Saudi Food and Drug Authority (SFDA) requirements, while 28.9% of all products that carried nutritional claims met SFDA criteria; however, the analysis indicated that products that carried health or nutritional claims were significantly lower in sugar (9.67 g/100 g), fat (9.2 g/100 g), saturated fat (3.2 g/100 g), and sodium (371.36 mg/100 g). According to the UKNPM, 46.9% of the products carrying claims were less healthy than those not carrying claims, and statistically significant differences were observed by product origin and category (p < 0.005 and p < 0.000, respectively). Conclusion The current representation of unregulated claims on food products may mislead the consumer. There is an urgent need for government legislation that limits their use except under certain conditions for the optimal protection of the population's health.

Health-related cues on the packages of processed and ultra-processed products: prevalence and policy implications. Br J Nutr 2022:1-11. [PMID: 36205217 DOI: 10.1017/s000711452200318x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 04/18/2023]
Abstract
The information included on food packages has a crucial role in influencing consumer product associations and purchase decisions. In particular, visual and textual cues on processed and ultra-processed products can convey health-related associations that influence consumer healthiness perception and purchase decisions. In this context, the present work aimed to explore the use of health-related cues on the packages of processed and ultra-processed products sold in Uruguay to provide insights for policy making. A total of 3813 products from thirty-four different food categories found in four of the most important supermarket chains in Uruguay were surveyed. The textual and visual information included on the packages as well as the nutritional composition of the products were analysed. Results showed that 67 % of the products included at least one health-related cue. Pictures of culinary ingredients, natural and minimally processed foods were the most frequent health-related cue, followed by references to naturalness and claims related to critical nutrients. The prevalence of health-related cues largely differed across product categories, ranging from 100 to 17 %. The relationship between the presence of health-related cues on the packages and the excessive content of nutrients associated with non-communicable diseases was assessed using a gradient boosting model, which showed limited predictive ability. This suggests that the inclusion of health-related cues on food packages was not strongly related to the nutritional composition of products and therefore cannot be regarded as a healthiness indicator. These results stress the need to develop stricter labelling regulations to protect consumers from misleading information.

Information displayed on Brazilian food bar labels points to the need to reformulate the current food labelling legislation. Food Chem 2022; 370:131318. [PMID: 34662792 DOI: 10.1016/j.foodchem.2021.131318] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 09/12/2021] [Accepted: 10/02/2021] [Indexed: 11/04/2022]
Abstract
This article compares information on the labels of Brazilian food bars with National Health Surveillance Agency legislation. Twenty-six brands of food bars were identified, comprising 50 commercial lines and 153 flavors. The marketing appeal to consumers on the front of pack labeling appeared in many ways to identify these products with a healthy and sustainable lifestyle. However, mandatory information was hard to see, both on the packaging and online, making it difficult for consumer to access. Most of the information on labels followed current legislation, but nutritional irregularities were identified since most bars were ultra-processed and one had incorrect information on the label. The claim that these foods are healthy reinforces the need to reformulate nutrition labeling in Brazil to facilitate identification of nutritional quality/value of foods as part of healthy and sustainable diets.

Estimated effects of the implementation of the Mexican warning labels regulation on the use of health and nutrition claims on packaged foods. Int J Behav Nutr Phys Act 2021; 18:76. [PMID: 34112183 PMCID: PMC8194035 DOI: 10.1186/s12966-021-01148-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2020] [Accepted: 06/02/2021] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND The use of health and nutrition claims on front-of-pack labels may impact consumers' food choices; therefore, many countries have established regulations to avoid misinformation. This study describes the prevalence of health and nutrition claims on the front-of-pack of food products in retail stores in Mexico and estimate the potential effects of the Official Mexican Standards 051 (new regulation that includes specifications for implementing warning labels and other packaging elements such as health and nutrition claims on less healthy foods) on the prevalence of these claims. METHODS This is a cross-sectional study in which health and nutrition claims, nutrition information panels, and the list of ingredients of all foods and beverages available in the main retail stores in Mexico City were collected. The products were grouped by level of processing according to the NOVA food system classification. Claims were classified using the internationally harmonized INFORMAS taxonomy. According to the criteria of the new Mexican front-of-pack labelling regulation, the effect on the reduction on the prevalence of health and nutrition claims was estimated by type of food and by energy and nutrients of concern thresholds. RESULTS Of 17,264 products, 33.8% displayed nutrition claims and 3.4% health claims. In total, 80.8% of all products in the Mexican market were classified as "less healthy"; 48.2% of products had excess calories, 44.6% had excess sodium, and 40.7% excess free sugars. The new regulation would prevent 39.4% of products with claims from displaying health and nutrition claims (P < 0.001); the largest reduction is observed for ultra-processed foods (51.1%, P < 0.001). The regulation thresholds that resulted in the largest reduction of claims were calories (OR 0.62, P < 0.001) and non-sugar sweeteners (OR 0.54, P < 0.001). CONCLUSIONS The new Mexican front-of-pack labelling regulation will prevent most processed and ultra-processed foods from displaying health and nutrition claims and will potentially improve information on packaging for consumers.

Nutrition Claims on Fruit Drinks Are Inconsistent Indicators of Nutritional Profile: A Content Analysis of Fruit Drinks Purchased by Households With Young Children. J Acad Nutr Diet 2021; 121:36-46.e4. [PMID: 32978105 PMCID: PMC7752796 DOI: 10.1016/j.jand.2020.08.009] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 07/30/2020] [Accepted: 08/05/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND Fruit drinks are the most commonly consumed sugar-sweetened beverage among young children. Fruit drinks carry many nutrition-related claims on the front of package (FOP). Nutrition-related claims affect individuals' perceptions of the healthfulness of products and purchase intentions, often creating a "health halo" effect. OBJECTIVE The aims of this study were to describe the prevalence of FOP nutrition-related claims on fruit drinks purchased by households with young children and to examine the association between claims and the nutritional profile of fruit drinks. DESIGN The sample included 2059 fruit drinks purchased by households with children 0 to 5 years old participating in Nielsen Homescan in 2017. FOP labels were obtained from 2 databases that contain bar code-level information on all printed material on product labels. A codebook was used to code for presence of FOP nutrition-related claims. The coded claims data were linked by bar code with Nutrition Facts label data. Claim type prevalence was calculated, and the association between claim types and median calories and total grams of sugar per 100 mL was analyzed using Wilcoxon rank-sum tests. The percentages of products containing noncaloric sweeteners (NCSs) with and without each claim type were also calculated and compared. RESULTS Almost all (97%) fruit drinks sampled had at least 1 nutrition-related FOP claim. Implied natural claims such as "natural flavors" were the most common (55% of products), followed by claims about the presence of juice or nectar (49%). Claims about vitamin C (33%), sugar (29%), and calories (23%) were also common. Fruit drinks with vitamin C, juice or nectar, fruit or fruit flavor, and overt natural claims were higher in calories and sugar and less likely to contain NCSs compared with products without these claims. Fruit drinks with calorie, sugar, NCS, implied natural, and other claims were lower in calories and sugar and more likely to contain NCSs compared with products without these claims. CONCLUSIONS Claims are prevalent on fruit drinks purchased by households with young children. This is concerning given prior research demonstrating that claims can mislead consumers. Regulatory actions such as requiring a warning or disclosure on drinks that contain added sugars or NCSs should be considered.

Abstract
OBJECTIVE The present study aimed at surveying the nutritional quality of prepacked biscuits and sweet snacks sold on the Italian market, and at identifying whether the product type and other information reported on the pack could discriminate the overall quality of products analysed. DESIGN Data on energy, nutrient and salt content of the products from two different categories of prepacked sweet cereal products (i.e. biscuits and sweet snacks) were collected from thirteen retailers present on the Italian market. Based on the product type, nutrition and health claim (NHC) and gluten-free (GF) declaration, a comparison of nutrient profile within each category was performed. SETTING This work is part of the Food Labelling of Italian Products (FLIP) study that aims at systematically investigating the overall quality of the prepacked foods sold on the Italian market. RESULTS A total of 1290 products were analysed (63 % biscuits and 37 % sweet snacks). After comparing different product types within each category, a high intra-type product variability was evidenced, which was more pronounced for biscuits. Overall, NHC-carrying products seemed to have a better nutrition profile than those without claims, except for salt content. Conversely, a comparison between GF and gluten-containing products did not show consistent results within the two categories analysed. CONCLUSIONS Due to the high intra-type variability within each category, the different characteristics and regulated information reported on the pack do not seem to be a clear marker of the overall nutritional quality of biscuits and snacks.

The impact of front-of-package claims, fruit images, and health warnings on consumers' perceptions of sugar-sweetened fruit drinks: Three randomized experiments. Prev Med 2020; 132:105998. [PMID: 31982477 PMCID: PMC7085890 DOI: 10.1016/j.ypmed.2020.105998] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2019] [Revised: 12/20/2019] [Accepted: 01/21/2020] [Indexed: 10/25/2022]
Abstract
We aimed to examine the impact of claims, fruit images, and health warnings on consumers' perceptions of fruit-flavored drinks with added sugar (i.e., "fruit drinks"). We conducted three 2x2x2 randomized experiments with online convenience samples of U.S. adults (Study 1 n = 2139 in 2018, current e-cigarette users and smokers; Study 2 n = 670 in 2018, current e-cigarette users; Study 3 n = 1006 in 2019, general sample). Participants viewed a fruit drink that differed in the presence of a "100% Vitamin C" claim, a fruit image, or a health warning. On average across the three studies, consumers who saw a claim on a fruit drink believed that the drink was more healthful than those who did not see the claim (mean average differential effect (ADE) = 0.66, p < .001); they were also more interested in consuming the drink (mean ADE = 0.38, p = .001). The health warning decreased perceived product healthfulness (mean ADE = -0.65, p < .001) and consumption interest (mean ADE = -0.49, p < .001). The fruit image had no effect on perceived product healthfulness (mean ADE = 0.03, p = .81) or purchase intentions (mean ADE = -0.04, p = .77). In Study 1 and Study 2, there were no interactions between claims, images, or warnings (all p > .05). In Study 3, the "100% Vitamin C" nutrition claim only increased perceived product healthfulness when the drink did not also have a health warning (interaction p < .05). These findings suggest that 100% Vitamin C claims increase the appeal of fruit drinks, whereas health warnings decrease the appeal. Together, these studies support policies to restrict marketing and require health warnings on sugar-sweetened beverage packaging.

Systematic review of the impact of nutrition claims related to fat, sugar and energy content on food choices and energy intake. BMC Public Health 2019; 19:1296. [PMID: 31615458 PMCID: PMC6794740 DOI: 10.1186/s12889-019-7622-3] [Citation(s) in RCA: 48] [Impact Index Per Article: 9.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2019] [Accepted: 09/13/2019] [Indexed: 11/15/2022] Open
Abstract
Background As part of efforts to address high levels of overweight and obesity, the provision of nutrition information (e.g., through nutrition labels and nutrition claims) on food packages has increasingly become an important policy option. This study aimed to assess the influence of nutrition claims relating to fat, sugar, and energy content on product packaging on several aspects of food choices to understand how they contribute to the prevention of overweight and obesity. Methods A systematic literature review was conducted using the online databases EBSCOhost Global Health, EBSCOhost Medline, ScienceDirect, Scopus, PsycINFO and Embase. Studies were included if they measured the influence of nutrition claims relating to fat, sugar, and energy content on outcomes related to body weight, and were published between January 2003 and April 2018. Results Eleven studies were included in the review. Results showed that nutrition claims can influence the knowledge of consumers with respect to perceived healthfulness of products, as well as expected and experienced tastiness of food products – making food products with nutrition claims seem healthier and less tasty. Nutrition claims can make the appropriate portion size appear to be larger and lead to an underestimation of the energy content of food products. Nutrition claims can also influence food purchase intentions, moderated by the perceived healthfulness of the relevant food products and the health consciousness of individuals. Nutrition claims were also found to have an impact on food purchases, to influence ‘consumption guilt’ (i.e., feeling of guilt associated with eating), and to increase consumption, moderated by the weight status of individuals. These influences were shown to vary depending on the type of claim and food carrying the claim. Conclusions There is evidence that, while nutrition claims may lead some consumers to improve their nutrition knowledge and select healthier options, it may also lead consumers to increase food consumption and overall energy intake. This may run counter to efforts to address overweight and obesity.

Consumers' purchase decisions for products with nutrition and health claims: What role do product category and gaze duration on claims play? Appetite 2019; 141:104337. [PMID: 31260708 DOI: 10.1016/j.appet.2019.104337] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 06/20/2019] [Accepted: 06/27/2019] [Indexed: 11/22/2022]
Abstract
Labeling food packages with nutrition and health claims is a widely used practice. This study aims to contribute to the literature by examining the gaze and purchase behavior of consumers regarding food products with nutrition and health claims. A close-to-realistic purchase situation with three-dimensional food packages with nutrition, health, and taste claims was simulated while the participants' eye movements were measured using head-mounted eye tracking glasses. In the purchase situation, two food categories with differing perceived healthiness were offered, orange juice and milk chocolate. In total, 156 consumers participated in this study which was undertaken in Germany. The findings indicate that each claim was noticed by at least 85% of the participants and health claims were looked at longer than nutrition or taste claims. Furthermore, when compared to other participants, the longer a participant looked at a specific claim, the more likely the participant was to purchase the respective product. Even though the product category had no effect on the gaze duration on claims, it affected the purchase behavior. Nutrition claims were preferred for orange juice while taste claims were preferred for milk chocolate. Health claims were preferred for neither. Marketers can benefit from this study, as it shows the gaze duration on claims influenced the purchase likelihood. Another important finding is that there are great differences between product categories regarding the type of claim consumers prefer.

Regulating health and nutrition claims in the UK using a nutrient profile model: an explorative modelled health impact assessment. Int J Behav Nutr Phys Act 2019; 16:18. [PMID: 30732626 PMCID: PMC6367824 DOI: 10.1186/s12966-019-0778-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Accepted: 01/30/2019] [Indexed: 11/26/2022] Open
Abstract
Background Health-related claims (HRCs) are statements found on food packets that convey the nutritional quality of a food (nutrition claims) and/or its impact on a health outcome (health claims). The EU stated that HRCs should be regulated such that they can only appear on foods that meet a specified nutrient profile (NP). A NP model has been proposed, but not agreed by the European Commission. Methods To model the impact of HRCs on health impacts in the UK, we built a front-end model to a pre-established non-communicable-disease (NCD) scenario model, the Preventable Risk Integrated ModEl (PRIME) by combining data from a meta-analysis examining the impact of HRCs on dietary choices and a survey of pre-packaged foods examining the prevalence of HRCs and the nutritional quality of foods that carry them. These data are used to model the impact of regulating HRCs on the nutritional quality of the diet and PRIME is used to model the health outcomes associated with these changes. Two scenarios are modelled: regulating HRCs with a NP model (the FSANZ NPSC and a draft EU model) so that only foods that pass the model are eligible to carry HRCs, and reformulating HRC-carrying foods that fail the model. Results Regulating the use of HRCs with a NP model (the FSANZ NPSC) would have unclear impacts on population health and could potentially lead to less healthy diets. This is because HRCs are currently more likely to be found on products with a better nutritional profile and restricting their use could shift consumers to less healthy diets. Two hundred fifty-eight additional deaths (95% Uncertainty Intervals [UI] -6509, 8706) were predicted if foods did not change in their nutrient composition. If all foods that currently carry HRCs were reformulated to meet the NP model criteria then there would be a positive impact of using the model: (4374 deaths averted (95%UI -2569, 14,009)). The largest contributor to the uncertainty is the underpowered estimates of nutritional quality of foods with and without claims. Conclusions Regulating HRCs could result in negative health impacts, however the wide uncertainty intervals from this analysis demonstrate that a larger health impact assessment is necessary.

Influence of nutritional warnings and other label features on consumers' choice: Results from an eye-tracking study. Food Res Int 2018; 119:605-611. [PMID: 30884695 DOI: 10.1016/j.foodres.2018.10.038] [Citation(s) in RCA: 31] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Revised: 10/08/2018] [Accepted: 10/09/2018] [Indexed: 11/26/2022]
Abstract
Nutritional warnings highlighting products with high content of nutrients associated with non-communicable diseases have emerged as a potentially efficient alternative to discourage consumption of unhealthful products. However, the relative influence of this front-of-pack nutrition information scheme compared to other label features is still under researched. In this context, the aim of the present work was to study the influence of nutritional warnings and other information commonly displayed on food labels to convey health associations on consumers' choice and visual attention. A choice-conjoint study using labels of cookies and crackers was implemented considering the following three variables: front-of-pack nutrition information (nutritional warnings vs. facts up front panel), nutrient claim (present vs. absent) and type of product (conveying health vs. hedonic associations). A total of 124 people completed the task using the monitor of an eye-tracker. Participants were asked to select the label they would prefer to buy if they were in a supermarket. Nutritional warnings were efficient in attracting consumers' attention and required less time and fewer fixations to process than the facts up front panel. In addition, their inclusion on the labels significantly discouraged consumers' choice of labels. However, type of product was the most important variable influencing the choice of both cookies and crackers. Results from the present work confirm the potential of nutritional warnings as directive front-of-pack nutrition labelling scheme and stress that they cannot be expected to cause radical changes in consumers' eating habits due to their competition with other product features. Instead, they are expected to encourage consumers to select the most healthful option within a product category.

Assessing nutrition and other claims on food labels: a repeated cross-sectional analysis of the Canadian food supply. BMC Nutr 2017; 3:74. [PMID: 32153852 PMCID: PMC7050703 DOI: 10.1186/s40795-017-0192-9] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Accepted: 08/16/2017] [Indexed: 11/10/2022] Open
Abstract
Background In 2010, nutrition claims were investigated in Canadian foods; however, many nutrition and other claims have been introduced since then. This study aimed to determine: i) the proportion of foods carrying claims in 2013, ii) the types and prevalence of nutrition claims (nutrient content claims, health claims, general health claims) and other claims displayed on labels in 2013, iii) and trends in use of nutrition claims between 2010 and 2013. Methods Repeated cross-sectional analysis of the University of Toronto Food Label Information Program (FLIP) of Canadian foods (2010/11 n = 10,487; 2013 n = 15,342). Regulated nutrition claims (nutrient content, health claims) were classified according to Canadian regulations. A decision tree was used to classify non-regulated general health claims (e.g., front-of-pack claims). Other claims (e.g., gluten-free) were also collected. Proportions of claims in 2013 were determined and χ2 was used to test significant differences for different types of claims between 2010 and 2013. Results Overall, 49% of products in 2013 displayed any type of claim and 46% of foods in FLIP 2013 carried a nutrition claim (nutrient content claim, health claim, general health claim). Meal replacements and fruits/fruits juices were the categories with the largest proportion of foods with claims. At least one approved nutrient content claim was carried on 42.9% of products compared to 45.5% in 2010 (p < 0.001). Health claims, specifically disease risk reduction claims, were slightly lower in 2013 (1.5%) compared to 1.7% in 2010 (p = 0.225). General health claims, specifically front-of-pack claims, were carried on 20% of foods compared to 18.9% in 2010 (p = 0.020). Other claims, specifically gluten-free, were present on 7.3% of foods. Conclusions Nutrition and other claims were used on half of Canadian prepackaged foods in 2013. Many claims guidelines and regulations have been released since 2010; however, little impact has been seen in the prevalence of such claims in the food supply. Claims related to nutrients of public health priority, such as sugars and sodium, were not commonly used on food labels. Monitoring trends in the use of nutrition and other claims is essential to determine if their use on food labels reflects public health objectives, or instead are being used as marketing tools.

Abstract
Objective To objectively evaluate voluntary nutrition and health claims and marketing techniques present on packaging of high-market-share ultra-processed foods (UPF) in Australia for their potential impact on public health. Design Cross-sectional. Setting Packaging information from five high-market-share food manufacturers and one retailer were obtained from supermarket and manufacturers’ websites. Subjects Ingredients lists for 215 UPF were examined for presence of added sugar. Packaging information was categorised using a taxonomy of nutrition and health information which included nutrition and health claims and five common food marketing techniques. Compliance of statements and claims with the Australia New Zealand Food Standards Code and with Health Star Ratings (HSR) were assessed for all products. Results Almost all UPF (95 %) contained added sugars described in thirty-four different ways; 55 % of UPF displayed a HSR; 56 % had nutrition claims (18 % were compliant with regulations); 25 % had health claims (79 % were compliant); and 97 % employed common food marketing techniques. Packaging of 47 % of UPF was designed to appeal to children. UPF carried a mean of 1·5 health and nutrition claims (range 0–10) and 2·6 marketing techniques (range 0–5), and 45 % had HSR≤3·0/5·0. Conclusions Most UPF packaging featured nutrition and health statements or claims despite the high prevalence of added sugars and moderate HSR. The degree of inappropriate or inaccurate statements and claims present is concerning, particularly on packaging designed to appeal to children. Public policies to assist parents to select healthy family foods should address the quality and accuracy of information provided on UPF packaging.

A systematic review, and meta-analyses, of the impact of health-related claims on dietary choices. Int J Behav Nutr Phys Act 2017; 14:93. [PMID: 28697787 PMCID: PMC5505045 DOI: 10.1186/s12966-017-0548-1] [Citation(s) in RCA: 97] [Impact Index Per Article: 13.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Accepted: 07/03/2017] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Health-related claims are statements regarding the nutritional content of a food (nutrition claims) and/or indicate that a relationship exists between a food and a health outcome (health claims). Their impact on food purchasing or consumption decisions is unclear. This systematic review measured the effect of health-related claims, on pre-packaged foods in retail settings, on adult purchasing decisions (real and perceived). METHODS In September 2016, we searched MEDLINE, EMBASE, PsychINFO, CAB abstracts, Business Source Complete, and Web of Science/Science Citation Index & Social Science Citation Index for articles in English published in peer-review journals. Studies were included if they were controlled experiments where the experimental group(s) included a health-related claim and the control group involved an identical product without a health-related claim. Included studies measured (at an individual or population level); actual or intended choice, purchases, and/or consumption. The primary outcome was product choices and purchases, the secondary outcome was food consumption and preference. Results were standardised through calculating odds ratios and 95% confidence intervals (CI) for the likelihood of choosing a product when a health-related claim was present. Results were combined in a random-effects meta-analysis. RESULTS Thirty-one papers were identified, 17 of which were included for meta-analyses. Most studies were conducted in Europe (n = 17) and the USA (n = 7). Identified studies were choice experiments that measured the likelihood of a product being chosen when a claim was present compared to when a claim was not present, (n = 16), 15 studies were experiments that measured either; intent-rating scale outcomes (n = 8), consumption (n = 6), a combination of the two (n = 1), or purchase data (n = 1). Overall, 20 studies found that claims increase purchasing and/or consumption, eight studies had mixed results, and two studies found consumption/purchasing reductions. The meta-analyses of 17 studies found that health-related claims increase consumption and/or purchasing (OR 1.75, CI 1.60-1.91). CONCLUSION Health-related claims have a substantial effect on dietary choices. However, this finding is based on research mostly conducted in artificial settings. Findings from natural experiments have yielded smaller effects. Further research is needed to assess effects of claims in real-world settings.

Abstract
Nutrition and health claims are displayed to influence consumers' food choices. This study assessed the extent and nature of nutrition and health claims on the front-of-pack of 'healthy' and 'less-healthy' packaged foods in New Zealand. Foods from eight categories, for which consumption may affect the risk of obesity and diet-related chronic diseases, were selected from the 2014 Nutritrack database. The internationally standardised International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support (INFORMAS) taxonomy was used to classify claims on packages. The Nutrient Profiling Scoring Criterion (NPSC) was used to classify products as 'healthy' or 'less healthy'. In total, 7526 products were included, with 47 % (n 3557) classified as 'healthy'. More than one-third of products displayed at least one nutrition claim and 15 % featured at least one health claim on the front-of-pack. Claims were found on one-third of 'less-healthy' products; 26 % of those products displayed nutrition claims and 7 % featured health claims. About 45 % of 'healthy' products displayed nutrition claims and 23 % featured health claims. Out of 7058 individual claims, the majority (69 %) were found on 'healthy' products. Cereals displayed the greatest proportion of nutrition and health claims (1503 claims on 564 products), of which one-third were displayed on 'less-healthy' cereals. Such claims could be misleading consumers' perceptions of nutritional quality of foods. It needs to be explored how current regulations on nutrition and health claims in New Zealand could be further strengthened (e.g. using the NPSC for nutrition claims, including general health claims as per the INFORMAS taxonomy) to ensure consumers are protected and not misled.

How many foods in the UK carry health and nutrition claims, and are they healthier than those that do not? Public Health Nutr 2015; 19:988-97. [PMID: 26156809 PMCID: PMC4825057 DOI: 10.1017/s1368980015002104] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/22/2022]
Abstract
Objective The present study aimed to measure the prevalence of different types of health and
nutrition claims on foods and non-alcoholic beverages in a UK sample and to assess the
nutritional quality of such products carrying health or nutrition claims. Design A survey of health and nutrition claims on food packaging using a newly defined
taxonomy of claims and internationally agreed definitions of claim types. Setting A national UK food retailer: Tesco. Subjects Three hundred and eighty-two products randomly sampled from those available through the
retailer’s website. Results Of the products, 32 % (95 % CI 28, 37 %) carried either a health or nutrition claim; 15
% (95 % CI 11, 18 %) of products carried at least one health claim and 29 % (95 % CI 25,
34 %) carried at least one nutrition claim. When adjusted for product category, products
carrying health claims tended to be lower in total fat and saturated fat than those that
did not, but there was no significant difference in sugar or sodium levels. Products
carrying health claims had slightly higher fibre levels than products without. Results
were similar for comparisons between products that carry nutrition claims and those that
do not. Conclusions Health and nutrition claims appear frequently on food and beverage products in the UK.
The nutrient profile of products carrying claims is marginally healthier than for
similar products without claims, suggesting that claims may have some but limited
informational value. The implication of these findings for guiding policy is unclear;
future research should investigate the ‘clinical relevance’ of these differences in
nutritional quality.
