RESUMEN

BACKGROUND: Few national studies across the United States' rural-urban continuum examine neighborhood effects on snacks and sweets intake among adults. OBJECTIVES: This study examines associations of urbanicity/rurality-tailored measures of food store availability and neighborhood socioeconomic status (NSES) with the intake of snacks and sweets in a national sample of middle and older age adults. METHODS: This cross-sectional study used food frequency questionnaire data collected in the REasons for Geographic And Racial Differences in Stroke study (N = 21,204). What We Eat in America food group categorizations guided outcome classification into 1 main category (total snacks and sweets) and 4 subcategories (savory snacks and crackers; sweet bakery products; candy and desserts; nutrition bars and low-fat snacks and sweets). NSES and food store availability were determined using geographic information systems. Food store availability was characterized as geographic access to primary food stores (e.g., supermarkets, supercenters, and select food retailers) in urbanicity/rurality-tailored neighborhood-based buffers. Multiple linear regression was used to predict each outcome. RESULTS: Living in neighborhoods with a high density of primary food stores was associated with 8.6%, 9.5%, and 5.8% lower intake of total snacks and sweets, sweet bakery products, and candy and desserts, respectively. Living in the highest NSES quartile was associated with 11.3%, 5.8%, and 18.9% lower intake of total snacks and sweets, savory snacks and crackers, and sweet bakery products, respectively. Depending on primary food store availability, higher household income was associated with significantly greater intake of nutrition bars and low-fat snacks and sweets. Living in a United States Department of Agriculture-defined food desert was not associated with intake. CONCLUSIONS: In a geographically diverse sample of middle and older age United States adults, living in neighborhoods with no primary food stores or neighborhoods of low-SES was associated with higher intake of total snacks and sweets and subgroups of snacks and sweets.

RESUMEN

The primary aim of this study was to examine the association between snack nutritional quality, overall diet quality and adiposity among Australian adolescents. The secondary aim was to assess the distribution of discretionary foods (i.e. energy-dense and nutrient-poor foods and beverages) and intakes from the five food groups at different levels of snack nutritional quality. Dietary data collected from nationally representative adolescents (12-18 years old) during a 24-h dietary recall in the National Nutrition and Physical Activity Survey were analysed (n 784). Snacks were defined based on participant-identified eating occasions. Snack nutritional quality was assessed using the Nutrient Profiling Scoring Criterion (NPSC), whereas diet quality was evaluated using the Dietary Guideline Index for Children and Adolescents. Adiposity was assessed through BMI Z-score waist circumference and waist:height ratio (WHtR). Higher nutritional quality of snacks, as assessed by the NPSC, has been associated with higher diet quality among both boys and girls (P < 0·001). However, there is no association between snacks nutritional quality with BMI Z-score, waist circumference and WHtR. Among both boys and girls, the consumption of fruits, vegetables and legumes/beans at snacks increased with improvement in snack nutritional quality. Conversely, the consumption of discretionary foods at snack decreased with improvement in snack nutritional quality. In conclusion, improved snack quality was associated with better diet quality in adolescents. However, there was no association between snack nutritional quality and adiposity. Future, snack nutrition quality indices should consider optimum snack characteristics related with adiposity and diet quality.

RESUMEN

OBJECTIVES: Individuals often use self-directed strategies to manage intake of tempting foods, but what these strategies are and whether they are effective is not well understood. This study assessed the frequency of use and subjective effectiveness of self-directed strategies in relation to BMI and snack intake. DESIGN: A cross-sectional and prospective study with three time points (T1: baseline, T2: 3 months and T3: 3 years). At T1, demographics, frequency of use and subjective effectiveness of forty-one identified strategies were assessed. At T2 and T3, current weight was reported, and at T2 frequency of snack intake was also recorded. SETTING: Online study in the UK. PARTICIPANTS: Data from 368 participants (Mage = 34·41 years; MBMI = 25·06 kg/m2) were used for analysis at T1, n = 170 (46·20 % of the total sample) at T2 and n = 51 (13·59 %) at T3. RESULTS: Two strategy factors were identified via principal axis factoring: (1) diet, exercise, reduction of temptations, and cognitive strategies, and (2) planning, preparation and eating style. For strategy 1, frequency of use, but not subjective effectiveness, was positively related to BMI at T1. Subjective effectiveness predicted an increase in BMI from T1 and T2 to T3. No relationship to snack intake was found. For strategy 2, frequency of use was negatively related to BMI at T1. Neither frequency of use nor subjective effectiveness were related to changes in BMI over time, but subjective effectiveness was negatively correlated with unhealthy snack intake. CONCLUSION: Self-directed strategies to reduce the intake of tempting foods are not consistently related to BMI or snack intake.

RESUMEN

OBJECTIVE: To understand the relationship between adolescents' unhealthy snacking behaviour during their school journey and their perceived and objective measures of food outlet availability in the school neighbourhood. DESIGN: A cross-sectional survey enquired about socio-demographic information, school transport modes, perceived presence of food outlets in the school neighbourhood and unhealthy food purchase and consumption on the school journey. A geographical information system analysis of the food outlets within 500 m and 1000 m school buffers was undertaken. Data were analysed using generalised linear mixed modelling. SETTING: All twelve secondary schools in Dunedin, Aotearoa New Zealand, March 2020-June 2022. PARTICIPANTS: Adolescents aged 13-18 years (n 725) who reported being familiar with their school neighbourhood. RESULTS: Perceived availability of food outlets in the school neighbourhood was inversely correlated with distance to the closest food outlet from school and positively correlated with food outlet density within 500 m and 1000 m school buffers. Adolescents' purchase and consumption of unhealthy snacks and drinks during the school journey were associated with perceived availability of food outlets and with shorter distance to the closest food outlet from school. Mixed transport users, girls and those living in high-deprivation neighbourhoods had higher odds of purchasing and consuming unhealthy snacks and drinks during the school journey than active transport users, boys and those living in low-deprivation neighbourhoods, respectively. CONCLUSIONS: Adolescents perceptions of the food environment and close access to food outlets in the school neighbourhood may influence adolescents' food purchase and consumption behaviours during the school journey.

RESUMEN

When making snack choices for children, parents are exposed to many child-targeted food packaging cues. This study aims to understand how different parental feeding goals (e.g. health versus fun versus taste) drive attention to these cues and how these cues help parents to make different snack choices. Qualitative interviews were conducted with 20 parents with at least one child between the ages of 3 and 12 years old. During the interviews, parents were primed with different feeding goals and asked to rank seven snack packages based on these goals. The interviews revealed three key takeaways regarding how parents consider snack packaging from a goal perspective. Firstly, packaging cues are interpreted (and thus used) differently when different feeding goals are salient. Secondly, cues are ignored when they do not offer valuable information for making goal-based assessments. Thirdly, when combining goals, parents either look for a combination of cues that fit their multiple goals, assess packaging based on a stepwise implementation of goals, or choose one dominant goal and rely on relevant packaging cues to rank snack packaging. This study widens the knowledge on how parental feeding goals can influence the food packaging choices parents make and the way in which they interpret packaging cues. The study can inspire policymakers by providing strategies to stimulate marketers to make the food environment healthier by steering consumers towards healthy food options and making these options more salient within environments where snacks are bought (e.g. supermarkets).

RESUMEN

As a way of modeling healthier eating habits for their children, parents may intentionally avoid consuming sugary foods and drinks (SFDs) in their presence but consume these on other occasions (later referred to as parental secretive eating). This study aimed to 1) explore the prevalence of parental secretive eating, 2) investigate the associations between parental secretive eating and SFD consumption in parents and children, and 3) qualitatively explore the reasons for parental secretive eating. Participants were Finnish mothers (n = 362), fathers (n = 123), and their 3-6-year-old children (n = 403); this data was collected in 2017 as part of the baseline assessment of the DAGIS intervention. Parents reported how often they avoided eating SFDs in the presence of their child, completed food frequency questionnaires for themselves and their child, and responded to an open-ended question of explaining reasons for secretive eating. The overall prevalence of parental secretive eating was 68%. It was more common among mothers than fathers (p < 0.001) and most prevalent in chocolate (61%) and sweets (59%). Parental secretive eating was positively associated with SFD consumption both among mothers (ꞵ = 0.274, p < 0.001) and fathers (ꞵ = 0.210, p = 0.028) in linear regression models adjusted for parents' and child's age, child's gender, parental education level, and number of household members. Mothers' or fathers' secretive eating and child's SFD consumption were not associated (ꞵ = 0.031, p = 0.562; ꞵ = -0.143; p = 0.167). Three themes describing reasons for parental secretive eating were found: family food rules, avoiding child's requests, and aspiration for healthy modeling. In conclusion, parental secretive eating may play an important role in determining SFD consumption in families with preschoolers. Additional research is needed to determine whether parents can prevent their own eating habits from influencing their child through secretive eating.

RESUMEN

The objective of this study is to examine whether the presence of peers has an impact on children's snack purchasing decisions. In particular, the research analyzes whether the company of a classmate or friend influences children's brand awareness and price perception, and how these factors affect their snack purchases. An incentive-based discrete choice experiment was conducted with snacks varying in price, brand, and healthiness, using the presence or absence of peers as a between-subject treatment. The data was analyzed using mixed logit models and a multinomial logit model. A total of 128 primary school children aged 8 to 10 years were included in the final data analysis. The findings show that the presence of peers strongly influences children's snack purchase decisions, particularly with respect to product type and price. The results highlight that children tend to conform to the group's decision, highlighting that social influence plays a crucial role in shaping children's decision-making processes. This study is the first to investigate the influence of peers on children's actual purchase decisions, thereby extending previous knowledge of the impact of peers on primary school children to the market domain.

RESUMEN

Each year, 2.8 million people die because of comorbidities associated with being overweight. Snacking substantially contributes to people's calorie intake. One way to nudge consumers towards healthier alternatives is the implementation of nutritional labeling. This study reports on a controlled field experiment that evaluates the effect of two nutritional labels on free snack choices (n = 739). Participants at a conference could choose between nuts, cookies, and candy bars as a snack, presented at the bar at six different locations across 2 bar counters. The labels were set up in front of each snack in three conditions: no labeling (control), a calorie label, or a traffic light label (i.e., the Nutri-Score). The location of the snacks on the counter (Either side of the counter; Center, Right, Left) and the time-of-day (Morning (=reference) vs Afternoon) were statistically controlled for. The results show that calorie labels could not successfully nudge consumers toward healthier snack choices (nuts instead of candy bars or cookies). In contrast, the Nutri-Score label significantly increased the probability of choosing nuts over candy bars. The Nutri-Score also increased the chance of choosing nuts over cookies, but the difference was not significant. No prior studies to our knowledge have directly compared calorie labels to the Nutri-Score. This study suggests that the Nutri-Score label can be a more successful intervention than calorie labels to nudge consumers towards healthier choices in situations were free snacks are offered, like many modern workplaces. Changing snacking behavior is challenging and naturalistic field experiments like this one are needed to translate the theory from previous laboratory studies to real-life settings.

RESUMEN

Innovation around cheese is constant in attempts to meet ever-increasing consumer demands. Retail packaging provides a canvas to communicate to consumers added value from innovations or inherent properties of cheese. Packaging itself may also be the subject of cheese-related innovation. This systematic review of literature organizes research over the past 10 years related to cheese packaging innovation that consumers experience in the marketplace and during consumption of cheese products. The review discusses shipping, displaying cheese at grocery stores, the value of branding, purchasing preferences by demographics, health and nutrition claims, opportunities to highlight protein in cheese, marketing to children, issues of obesity and cheese, diet cheeses, allergens and non-dairy or vegan cheese, opening cheese packaging, cutting of cheese, cooking with cheese, eating cheese, the growing trend of snacking and convenience, and flavor preferences. This review provides helpful insights to cheese producers applying findings from research of various styles of cheeses, cheese marketers communicating effectively to consumers, cheese developers designing new products relevant to recent consumer demands, smaller or specialized companies seeking to differentiate their cheese product through available technology and strategy, and cheese lovers or those with hobbies surrounding food wanting to know recent advancements in cheese packaging. This review is a tool for discovering relevant articles relating to cheese packaging in a marketplace and consumption setting to guide cheese and cheese packaging and labeling innovation in the United States.

RESUMEN

Several studies have reported high overweight and obesity incidence among schoolchildren and adolescents, who mostly consume packaged snacks with critical nutrients exceeding the criteria of international profiling systems during school breaks. Then, the objectives of this work were to reformulate a snack consumed by Argentinian schoolchildren and adolescents (aged 6-13 years) to decrease its critical nutrient contents and to determine if this product would still be accepted. Chocolate chip vanilla cookies were selected for reformulation considering each recommended cut-off point for critical nutrients, since a prohibition of products with warning octagons being offered at schools would come into effect in Argentina. These cookies received good acceptability scores (above 3 of 5 points) and would be consumed by 8 of 10 schoolchildren in a sample of 200 participants. These findings underscore the importance of legislation promoting awareness of healthier eating habits and increasing the availability of healthier food options in schools.

RESUMEN

This work aimed to develop gluten-free snacks such as crispbread based on beetroot pomace (Beta vulgaris L.) and golden linseed (Lini semen). Beetroot is attracting more and more consumer attention because of its nutritional and health properties. The use of beet pomace contributes to waste management. Linseed, known as a superfood with many health-promoting properties, was used to produce crispbreads as an alternative to cereals, which are allergens. Beetroot pomace and whole or ground linseed were used in different proportions to produce crispbread snacks. Chemical and physical analyses were performed including water activity, dry matter, betalains, and polyphenols content, as well as Fourier transform infrared spectroscopy (FTIR). A sensory evaluation and microstructure observations were also performed. The obtained snacks were characterized by low water activity (0.290-0.395) and a high dry matter content (93.43-97.53%), which ensures their microbiological stability and enables longer storage. Beetroot pomace provided betalains-red (14.59-51.44 mg betanin/100 g d.m.) and yellow dyes (50.02-171.12 mg betanin/100 g d.m.)-while using linseed enriched the product with polyphenols (730-948 mg chlorogenic acid/100 g d.m.). FTIR analysis showed the presence of functional groups such as the following: -OH, -C-O, -COOH, and -NH. The most desired overall consumer acceptability was achieved for snacks containing 50% beetroot pomace and 50% linseed seeds. The obtained results confirmed that beetroot pomace combined with linseed can be used in the production of vegetable crispbread snacks.

RESUMEN

BACKGROUND: Temperament associated with oral health behaviour and early childhood caries (ECC) in preschoolers remains inconclusive. AIM: This cross-sectional study investigated the association of temperament with oral health behaviour and ECC status. DESIGN: A total of 421 Thai preschoolers were recruited from elementary schools in Chonburi Province, Thailand. Their caregivers assessed three temperament dimensions (surgency, negative affectivity and effortful control) using the Thai version of the Children's Behaviour Questionnaire Very Short Form and reported oral health behaviours (brushing cooperation and cariogenic snack frequency). Three calibrated dentists assessed ECC status using the modified WHO dmft/dmfs (decayed, missing and filled teeth/surface) index that included noncavitated and cavitated carious lesions. RESULTS: Multiple regression analysis, after adjusting for child's and caregiver's characteristics, revealed that children with high negative affectivity or low effortful control were more likely to have uncooperative brushing behaviour. The temperament scores of children who consumed cariogenic snacks daily and those who did not were comparable. Children with low surgency, high negative affectivity or low effortful control were more likely to have high dmfs scores. CONCLUSION: Negative affectivity and effortful control were associated with brushing behaviour. Temperament was not associated with the frequency of cariogenic snack consumption. All temperamental dimensions, however, were associated with ECC.

RESUMEN

OBJECTIVES: This study aimed to comprehensively assess the weight status, snack consumption, and physical activity levels among primary schoolchildren, with a focus on both rural and urban areas. METHODS: This cross-sectional study surveyed 557 primary schoolchildren aged 6 to 12 years, covering general identification (age, gender), anthropometric measurements (body weight, height, waist, and hip circumference), food patterns (frequency of food consumption), and sports activities. RESULTS: Using CDC body mass index thresholds, we identified a 25% prevalence of obesity and over 17% for overweight, revealing a significant urban-rural disparity. In urban areas, boys had a higher obesity rate (32.58%), while girls had a higher overweight rate (15%). Conversely, in rural regions, girls had a higher obesity rate (24.82%), and boys had a higher overweight rate (22.3%). Dietary analysis showed that over 86% consumed three daily meals, but distinctions in snack choices, such as chips, wafers, and biscuits, were noted between urban and rural areas. Additionally, urban schoolchildren were more likely to participate in sports activities compared to their rural counterparts, with rates of 70.22% versus 55.08%, respectively. CONCLUSION: Findings provide valuable insights into the health and food behaviors of primary schoolchildren and can inform interventions and strategies to promote healthier lifestyles.

RESUMEN

BACKGROUND: Consumption of pseudocereal-based foods decreased in phytate concentration can provide better nutrition concerning mineral bioavailability. This study aimed to evaluate the mineral bioavailability of quinoa sourdough-based snacks in a murine model. The mice were divided into five groups. One group was fed with basal snacks; three control groups received quinoa-based snacks made from non-fermented dough, dough without inoculum, and chemically acidified dough; and the test group (GF) received quinoa snacks elaborated from sourdough fermented by a phytase-positive strain, Lactiplantibacillus plantarum CRL 1964. Food intake, body weight, and mineral concentration in blood and organs (liver, kidney, and femur) were determined. RESULTS: Food consumption increased during the feeding period and had the highest (16.2-24.5%) consumption in the GF group. Body weight also increased during the 6-weeks of trial. The GF group showed higher (6.0-10.2%) body weight compared with the other groups from the fifth week. The concentrations of iron, zinc, calcium, magnesium, and phosphorus in blood, iron and phosphorus in the liver, manganese and magnesium in the kidney, and calcium and phosphorus in the femur increased significantly (1.1-2.7-fold) in the GF group compared to the control groups. CONCLUSION: The diet that includes quinoa snacks elaborated with sourdough fermented by phytase-positive strain L. plantarum CRL 1964 increased the concentrations of minerals in the blood, liver, kidney, and femur of mice, counteracting the antinutritional effects of phytate. This study demonstrates that the diminution in phytate content and the consequent biofortification in minerals are a suitable tool for producing novel foods. © 2024 Society of Chemical Industry.

RESUMEN

BACKGROUND: Tomato is an indispensable ingredient of the Mediterranean diet. Reformulation of traditional Mediterranean products to increase the adherence of consumers is becoming popular. In this study, a tomato snack bar enriched with olive powder and pea protein was developed by using microwave-vacuum drying. Formulations also included tomato powder (TP) and low-methoxylated pectin (LMP) as a structuring agent. RESULTS: The moisture content of microwave-vacuum-dried samples varied in the range 13.6-19.8% and water activity (aw ) values were ~0.6. LMP and TP concentrations affected the color of microwave-vacuum-dried samples. However, the color mainly changed in conventionally dried samples due to browning. In microwave-vacuum-dried samples, lycopene content decreased with increasing LMP, but increased with increasing TP. Textural properties of microwave-vacuum-dried snack bars increased with increasing LMP and TP. CONCLUSION: Both texture and Fourier transform infrared spectroscopy results indicated that there was a network formation due to the contribution of protein and pectin; however, the type of interaction was highly dependent on the drying mechanism. Nuclear magnetic resonance relaxometry data showed that microwave-vacuum-dried samples had a more uniform water distribution. Besides its time and energy efficiency, microwave-vacuum drying improved the color and textural properties of tomato snack bars compared to conventionally dried ones. © 2023 The Authors.

RESUMEN

BACKGROUND: Three-dimensional (3D) food printing is a promising method for developing nutritious snack foods with complex and customized structures. In this study, to develop a pearl millet-based snack formulation, the printability of pearl millet flour (PMF) was assessed, without and with the addition of banana pulp (BP), a natural taste and flavor enhancer, at five different levels (PMF:BP of 100:0, 80:20, 60:40, 40:60, 20:80 and 0:100). RESULTS: The water activity significantly decreased with increases in the proportion of BP; higher water activity was exhibited at 100:0 (0.99). The BP proportion influences all the color values (redness: 2-11; yellowness: 17-31.87; total color difference: 2-17). All formulations exhibited shear-thinning behavior (n = 0.02-0.49) and higher hardness (0.2-0.4 N), but not all were printable. A significant decrease in adhesiveness (-0.2 to -0.03 N s) and higher storage modulus (2000-6000 Pa) occurred with an increased proportion of BP. Findings from detailed rheological behavior assessment (static, dynamic and three-interval thixotropy tests) better correlated with trends observed during 3D extrusion printing. The highest yield stress was attained (80 Pa) in the 100:0 formulation. From the thixotropy test, more deformation (>80%) and recovery (>100%) were attained by three of the formulations (100:0, 80:20, 60:40). Overall, the best constructs were obtained (based on the visual sensory characteristics) for the 60:40 formulation printed at 600 mm min-1 printing speed and 240 rpm extrusion motor speed through a 1.22 mm nozzle. CONCLUSION: The findings of this work will provide valuable insights into the development of novel millet-based 3D printed foods. © 2024 Society of Chemical Industry.

RESUMEN

The concept of plant-based protein consumption has been increasing recently because of the growing health consciousness among people. Mung bean is one of the most consumed legumes with a dense nutrient profile. Hence, current research is aimed to study the effect of mung bean protein-based products including mung bean snack (MBS) and textured vegetable protein (TVP) for treatment groups against the control groups, commercial ingredients group consisting of mung bean powder (MBP) and pea powder (PP) and commercial products group include commercial pea texture (cPT) and commercial textured vegetable protein (cTVP) for their proximate composition, digestibility, gut microbial profile and fatty acid metabolite profiling. The MBS and TVP samples had significantly higher digestibility of 74.43% and 73.24% than the commercial products. The protein content of TVP was 0.8 times higher than its commercial control. Gut microbiome profiling showed that all the samples shared around 162 similar genera. Post-fermentation analysis provided promising results by reflecting the growth of beneficial bacteria (Parabacteroides, Bifidobacterium and Lactobacillus) and the suppression of pathogens (Escherichia-Shigella, Dorea and Klebsiella). The dual relationship between gut microbiota and nutrient interaction proved the production of abundant short- and branched-chain fatty acids. The MBS sample was able to produce SCFAs (41.27 mM) significantly and BCFAs (2.02 mM) than the TVP sample (27.58 mM and 2.14 mM, respectively). Hence, our research outcomes proved that the mung bean protein-based products might infer numerous health benefits to the host due to enriched probiotics in the gut and the production of their corresponding metabolites.

RESUMEN

The development of a technological scheme for the production of cereal snacks based on the extrusion process with preliminary enzymatic treatment of wheat flour and the use of hydrolysate as a partial replacement for gluten-free raw materials is an urgent task. The use of gluten-free cereal snacks in the diet opens up new possibilities for dietary therapy in patients suffering from various manifestations of food allergy to gluten, making their diet more diverse and meeting their individual needs. The purpose of the research was to clinically evaluate the tolerance of gluten-free cereal snacks in children with PA to gluten. Material and methods. The study included 21 patients (male and female) aged 3 to 17 years with a diagnosed food allergy, including gluten. All children received gluten-free cereal snacks according to their age: children from 3 to 7 years old (n=11) received 50 g (176 kcal) daily, and children aged 8 to 17 years old (n=10) received 100 g (352 kcal) daily for 14 days, in addition to a non-specific hypoallergenic diet excluding highly allergenic foods. On the first day of the study, the patients or one of their parents evaluated the organoleptic properties of the presented product (taste, color, smell) using a 5-point scale (1 - very bad, 5 - excellent), according to a specially designed questionnaire. The assessment of clinical symptoms over time related to skin, gastrointestinal tract, and nervous system was conducted using a second questionnaire, where parents kept a daily «observation log¼ reflecting the child's well-being and condition, as well as adverse events associated with taking the product. Clinical safety parameters were assessed based on the dynamics of complete blood count and blood immunological parameters (total IgE, specific IgE, and IgG4 antibodies to the studied allergens) at the beginning and end of the consumption period. Results. Daily examinations and patient questionnaires revealed no adverse reactions to the product. No significant differences in body weight were observed at the end of the study (p>0.05). In the results of clinical and immunological blood analysis before and after consuming gluten-free cereal snacks, no significant deviations were observed in the form of an increase in eosinophil count, total IgE, allergen-specific IgE and IgG4 antibodies in peripheral blood. This suggests a favorable clinical safety profile of the proposed product. Conclusion. The study found that consumption of the new product (gluten-free cereal snacks) was well-tolerated by children aged 3 to 17 years with various manifestations of food allergy: no adverse effects of the product or exacerbations of the underlying disease were observed during the 14-day period of gluten-free cereal snack consumption. Therefore, the studied gluten-free cereal snacks can be recommended for children aged 3 to 17 years with various manifestations of gluten FA, in combination with a gluten free diet.

RESUMEN

BACKGROUND: There has been little investigation into how the timing of meals and eating occasions associates with postmenopausal breast cancer risk. OBJECTIVE: We examined the association between the frequency of consuming breakfast meals and after-dinner snacks with the risk for postmenopausal breast cancer. METHODS: A prospective analysis of 74,825 postmenopausal women aged 49 to 81 y from the Women's Health Initiative Observational Study cohort. Breakfast and after-dinner snack intake were assessed at year 1 examination. Risk for invasive and in situ breast cancer diagnosed before 28 February 2020 was modeled with multivariable Cox proportional hazards regression models according to breakfast and after-dinner snack consumption frequencies. The models were adjusted for age, self-identified race/ethnicity, education, income, physical activity, smoking, alcohol intake, diet quality score (Healthy Eating Index 2015), energy intake, diabetic status, hormone therapy, and BMI. RESULTS: During the follow-up period, 5313 participants were diagnosed with invasive breast cancer and 1197 participants with in situ breast cancer. Compared with participants who did not eat breakfast, those with daily breakfast consumption was not associated with invasive breast cancer (HR: 1.04; 95% CI: 0.9, 1.19) nor in situ (HR: 1.25; 95% CI: 0.91, 1.74) breast cancer. There were monotonic higher point estimates of in situ breast cancer for each higher category of breakfast intake from 0 to 7 times per week (P-trend = 0.04, Wald test). Compared with consumption of daily after-dinner snacks, avoidance of after-dinner snacks was not associated with invasive breast cancer (HR: 0.97; 95% CI: 0.87, 1.08) nor in situ (HR: 1.12; 95% CI: 0.89, 1.42) breast cancer. CONCLUSIONS: There was no association between intake frequency of breakfast meals or after-dinner snack habits and with risk of breast cancer in postmenopausal women.

RESUMEN

Policy Points Suboptimal diet is a leading cause of mortality and morbidity in the United States. Excise taxes on junk food are not widely utilized in the United States. The development of a workable definition of the food to be taxed is a substantial barrier to implementation. Three decades of legislative and regulatory definitions of food for taxes and related purposes provide insight into methods to characterize food to advance new policies. Defining policies through Product Categories combined with Nutrients or Processing may be a method to identify foods for health-related goals. CONTEXT: Suboptimal diet is a substantial contributor to weight gain, cardiometabolic diseases, and certain cancers. Junk food taxes can raise the price of the taxed product to reduce consumption and the revenue can be used to invest in low-resource communities. Taxes on junk food are administratively and legally feasible but no definition of "junk food" has been established. METHODS: To identify legislative and regulatory definitions characterizing food for tax and other related purposes, this research used Lexis+ and the NOURISHING policy database to identify federal, state, territorial, and Washington DC statutes, regulations, and bills (collectively denoted as "policies") defining and characterizing food for tax and related policies, 1991-2021. FINDINGS: This research identified and evaluated 47 unique laws and bills that defined food through one or more of the following criteria: Product Category (20 definitions), Processing (4 definitions), Product intertwined with Processing (19 definitions), Place (12 definitions), Nutrients (9 definitions), and Serving Size (7 definitions). Of the 47 policies, 26 used more than one criterion to define food categories, especially those with nutrition-related goals. Policy goals included taxing foods (snack, healthy, unhealthy, or processed foods), exempting foods from taxation (snack, healthy, unhealthy, or unprocessed foods), exempting homemade or farm-made foods from state and local retail regulations, and supporting federal nutrition assistance objectives. Policies based on Product Categories alone differentiated between necessity/staple foods on the one hand and nonnecessity/nonstaple foods on the other. CONCLUSIONS: In order to specifically identify unhealthy food, policies commonly included a combination of Product Category, Processing, and/or Nutrient criteria. Explanations for repealed state sales tax laws on snack foods identified retailers' difficulty pinpointing which specific foods were subject to the tax as a barrier to implementation. An excise tax assessed on manufacturers or distributors of junk food is a method to overcome this barrier and may be warranted.
