Article Synopsis
  • Young consumers often find nutrition facts tables (NFTs) on packaged foods confusing, which has led to the adoption of simpler front-of-package labels (FOPLs) in various countries, including Mexico's recent shift to 'Warning' FOPLs that highlight unhealthy nutrients with stop signs.
  • A study compared the awareness and understanding of NFTs and FOPLs among young people in Mexico and five other countries, analyzing changes before and after Mexico implemented its 'Warning' policy through national surveys conducted in 2019 and 2020.
  • Results indicated that young people in Mexico showed significantly higher awareness, use, and understanding of the 'Warning' FOPLs compared to NFTs, with a pronounced difference in Mexico after the policy change compared

Background: Front-of-pack labeling (FOPL) has been identified as a cost-effective policy to promote healthy diets. Health Canada has recently published FOPL regulations that will require food and beverages that meet or exceed set thresholds for sodium, sugars, or saturated fat to display a 'high in' symbol on the front of the package. Although a promising measure, its potential impact on dietary intakes and health have not yet been estimated in Canada.

Weight bias and discrimination are highly pervasive and harmful to Canadians with higher weights. Researchers and practitioners who deliver, evaluate, and advise on dietary and weight-related interventions may inadvertently perpetuate weight bias through their work; however, trainees in these fields rarely have access to weight bias education within their applied health programs. This study evaluated the acceptability of an online educational weight bias module developed for undergraduate students enrolled in health courses.

Few studies have compared the effects of different front-of-package label (FOPL) systems in the 'real world'. This study assessed adults' awareness, use and understanding of nutrition facts labels (NFLs) and nationally implemented FOPLs such as Health Star Ratings (HSR), Traffic lights, and Guideline Daily Amounts (GDAs) in five countries, including before and after implementation of Mexico's warning FOPLs in 2020. Data were from the International Food Policy Study, an annual repeat cross-sectional study conducted in 2018-2020 among adults (N=64,032) in Australia, Canada, Mexico, the UK and the US.

An unhealthy diet is among the leading global causes of death and disability. Globally, a range of policies are being implemented to support healthy food choices at a population level, including novel polices in the areas of food marketing, nutrition labeling, and taxation of less healthy foods. There is a need to evaluate and inform the implementation of these policies, including their impacts on marginalized population subgroups.

Front-of-package (FOP) nutrition labels have been proposed as a strategy to help limit sugar-sweetened beverage (SSB) consumption among youth. However, few studies have examined the efficacy of FOP labels in youth across different countries. A between-group experiment was conducted to examine the impact of FOP labels (no-label control, Health Star Rating, 'High in' Octagon, Guideline Daily Amount (GDA), Traffic Light, or Nutri-Score) on perceived healthfulness of an SSB.

Background: Front-of-package (FOP) nutrition labeling systems differ in how they rate food and beverage products. There is a need to examine the implications of these differences, including their focus on nutrients of public health concern.

Objective: Our aim was to examine the impacts of 4 common FOP labels on consumers' purchases of products that received conflicting ratings across FOP systems.

Objective: In February 2020, San Francisco proposed mandatory health warnings for sugar-sweetened beverage (SSB) advertisements. Industry legal challenges stated that the warning would detract from advertisers' ability to convey their intended message and mislead consumers into believing that SSB cause weight gain regardless of consumption amount, lifestyle or intake of other energy-dense foods.

Design: Online between-group experiments tested the impact of SSB warnings on advertising outcomes and consumer perceptions.

Background: Caffeine is a widely consumed stimulant, and caffeine-containing products are increasingly available on the market. Few tools are available to capture caffeine intake, particularly among young adults. To estimate caffeine consumption in the previous 24 hours, the 24-Hour Caffeine Intake Recall (CIR-24) was modeled after the Automated Self-Administered 24-Hour Dietary Assessment Tool, using a brand-specific database of caffeine-containing foods, beverages, and supplements.

Objective: To examine consumers' ability to correctly interpret front-of-package (FOP) 'high in' warnings in the presence of a voluntary claim for the same or a different nutrient.

Design: A between-group experimental task assigned respondents to view food products labelled as 'high in sodium', with a 'reduced sodium' claim positioned next to the warning, away from the warning or absent. A second experiment assigned participants to view a food product labelled as 'high in sugar', with a 'reduced fat' claim positioned next to the warning, away from the warning or absent.

Objective: This study aimed to test the industry claim that "high in" front-of-package (FOP) labeling systems are perceived as harsh and reduce consumers' control over food choices.

Methods: Respondents aged 16 to 32 years completed a between-group experimental task in an online survey (n = 1,000). Participants viewed a beverage with one of four FOP labels (text-only, octagon, triangle, or health star rating) and rated the label on its "harshness" and whether it made them feel more or less "in control" of their healthy eating decisions.
