Package Information Used by Older Adults to Identify Whole Grain Foods

Understanding Whole Grain Consumption among Low-Income Older Adults Using the Theory of Planned Behavior

Older adults have low whole grain (WG) intake. This qualitative study used the Theory of Planned Behavior (TPB) to identify low-income older adults' WG beliefs. A convenience sample of 25 low-income adults 60 years and older were interviewed using questions developed based on TPB constructs: behavioral, normative, and control beliefs. Interviews were audio-recorded, transcribed verbatim, cross-checked for consistency, and analyzed using content analysis. Study results revealed that regarding behavioral beliefs, health benefits, taste, and nutrition were WG advantages and sensory qualities, higher cost, and longer cooking time were disadvantages. Regarding normative beliefs, healthcare professionals and family members approved WG intake and those less informed about WGs disapproved. Regarding control beliefs, availability/accessibility, knowledge of WG benefits, and WG cooking skills facilitated WG intake and age-related changes, WG cost, decreased motivation to cook, and low knowledge (label reading) were barriers. Results provide insights for developing programs to increase older adults' WG intake.

Consumer confusion about wholegrain content and healthfulness in product labels: a discrete choice experiment and comprehension assessment

OBJECTIVE

Using a legal standard for scrutinising the regulation of food label claims, this study assessed whether consumers are misled about wholegrain (WG) content and product healthfulness based on common product labels.

DESIGN

First, a discrete choice experiment used pairs of hypothetical products with different amounts of WG, sugar and salt to measure effects on assessment of healthfulness; and second, a WG content comprehension assessment used actual product labels to assess respondent understanding.

SETTING

Online national panel survey.

PARTICIPANTS

For a representative sample of US adults (n 1030), survey responses were collected in 2018 and analysed in 2019.

RESULTS

First, 29-47 % of respondents incorrectly identified the healthier product from paired options, and respondents who self-identified as having difficulty in understanding labels were more likely to err. Second, for actual products composed primarily of refined grains, 43-51 % of respondents overstated the WG content, whereas for one product composed primarily of WG, 17 % of respondents understated the WG content.

CONCLUSIONS

The frequency of consumer misunderstanding of grain product labels was high in both study components. Potential policies to address consumer confusion include requiring disclosure of WG content as a percentage of total grain content or requiring disclosure of the grams of WG v. refined grains per serving.

Main Factors Influencing Whole Grain Consumption in Children and Adults-A Narrative Review

Despite their recognized health benefits, intakes of whole grains (WG) are below recommended levels in almost all countries worldwide. This observation highlights the need to increase WG consumption by understanding factors influencing this consumption and how they could be favorably impacted. This review focused on facilitators of and barriers to WG consumption and how to improve the effectiveness of programs aiming at increasing WG consumption. The main methods to facilitate WG intakes in both adults and children seem to be to (i) increase the availability and the variety of foods containing WG, (ii) improve their sensory appeal, (iii) reduce their purchase cost, (iv) use a familiarization period to introduce them to consumers (with a gradual increase in consumed amounts and repeated exposure), and (v) improve communication and labeling to enhance consumers’ ability to identify products with WG. These strategies may be used to improve the effectiveness of programs aiming at promoting WG consumption, with a further emphasis on the need to apply them over a long period of time, and potentially to include tasting sessions of new foods containing WG. Finally, these strategies should involve broad partnerships between multiple stakeholders at the regulatory, institutional and industrial levels.

Factors Associated with Identification and Consumption of Whole-Grain Foods in a Low-Income Population

BACKGROUND

US Dietary Guidelines include recommendations to increase whole-grain consumption, but most Americans, especially low-income adults, fail to consume adequate amounts.

OBJECTIVES

The aim of this study was to determine major factors that may affect whole-grain consumption among low-income adults.

METHODS

A mixed methods approach including a whole-grain food identification activity and in-depth interview was used to determine the factors that influence whole-grain consumption based on the constructs of the integrative behavioral model. Participants were recruited from food pantries in the northeastern United States. Descriptive statistics were conducted for demographic data and survey scores, and logistic regression was used to examine differences in whole-grain accuracy by demographic characteristics.

RESULTS

Low-income adults (n = 169) completed a quantitative survey, with a subset (n = 60) recruited for an in-depth qualitative interview. When completing the whole-grain identification activity, most low-income adults identified popcorn incorrectly as refined grain (71%), whereas the refined-grain food commonly identified as whole grain was white rice (42%). Less than half of low-income adults (46%) identified the majority of whole-grain foods correctly. Age, race, and education were not associated with the ability to identify whole-grain foods correctly. However, younger adults (aged 18-49 y) were less likely to identify popcorn as a whole-grain food (OR = 0.42, P = 0.02) compared with older adults (aged ≥50 y). According to the qualitative results, additional barriers, such as perceived cost, may also affect whole-grain food consumption among low-income adults.

CONCLUSIONS

Low-income adults' ability to correctly identify whole-grain foods and having a perception that whole-grain foods are higher in cost may be the overarching barriers to consuming adequate amounts. Future efforts should focus on strategies improving identification and seeking affordable whole-grain foods to increase whole-grain consumption in low-income adults.

Infant Cereals: Current Status, Challenges, and Future Opportunities for Whole Grains

Infant cereals play an important role in the complementary feeding period. The aim of this study was to review existing research about the quantity, type, and degree of infant cereal processing, with a special focus on whole grain infant cereals. Accumulating evidence shows many benefits of whole grain consumption for human health. Likewise, consumers are frequently linking the term whole grains to healthiness and naturality, and sustainable food production becomes a more important aspect when choosing an infant cereal brand. Whole grain cereals should be consumed as early as possible, i.e., during infancy. However, there are several challenges that food manufacturers are facing that need to be addressed. Recommendations are needed for the intake of whole grain cereals for infants and young children, including product-labeling guidelines for whole grain foods targeting these age stages. Another challenge is minimizing the higher contaminant content in whole grains, as well as those formed during processing. Yet, the greatest challenge may be to drive consumers' acceptance, including taste. The complementary feeding period is absolutely key in shaping the infant's food preferences and habits; therefore, it is the appropriate stage in life at which to introduce whole grain cereals for the acceptance of whole grains across the entire lifespan.

Consumers' health-related perceptions of bread - Implications for labeling and health communication

There is a wide variety of commercial bread types and the present study identifies potential pitfalls in consumer evaluations of bread from a health perspective. The aim is to describe consumers' health-related perceptions of bread by exploring which health-related quality attributes consumers associate with bread and whether there are differences with regard to age, gender and education level. A postal and web-based sequential mixed-mode survey (n = 1134, 62% responded online and 38% by paper) with open-ended questions and an elicitation task with pictures of commercial breads were used. Responses were content analyzed and inductively categorized. Three fourths (n = 844) knew of breads they considered healthy; these were most commonly described using terms such as "coarse," "whole grain," "fiber rich," "sourdough," "crisp," "less sugar," "dark," "rye," "seeds," "a commercial brand," "homemade" and "kernels." The breads were perceived as healthy mainly because they "contain fiber," are "good for the stomach," have good "satiation" and beneficial "glycemic properties." The frequency of several elicited attributes and health effects differed as a function of age group (18-44 vs. 45-80 years), gender and education level group (up to secondary education vs. university). Difficulties identifying healthy bread were perceived as a barrier for consumption especially among consumers with a lower education level. Several of the health effects important to consumers cannot be communicated on food packages and consumers must therefore use their own cues to identify these properties. This may lead to consumers being misled especially if a bread is labeled e.g., as a sourdough bread or a rye bread, despite a low content.
