Evaluating compliance with local and International Food Labelling Standards in urban Tanzania: a cross-sectional study of pre-packaged snacks in Dar Es Salaam.

BACKGROUND: Urbanization influences food culture, particularly in low- and middle-income countries where there is an increasing consumption of processed and pre-packaged foods. This shift is contributing to a rise in non-communicable diseases. Food labelling standards are crucial for regulating manufacturing practices and helping consumers make healthy food choices. We aimed to assess the compliance of local and imported pre-packaged snacks with Tanzanian and international labelling standards in Dar es Salaam, Tanzania. METHODOLOGY: A cross-sectional study was conducted on 180 snack products. A checklist based on Tanzanian and Codex labelling standards was used to evaluate adherence. We also examined factors influencing adherence, such as product origin, price, category, purchase location, and package size. RESULTS: The majority of the snacks demonstrated partial adherence to Tanzania (n = 97; 54%) and International (Codex) (n = 120; 67%) labelling standards. Imported products showed significantly better adherence to both Tanzanian (n = 46; 53%) and international (n = 42; 48%) standards. Notably, more than half (n = 110; 66.7%) of the products used English for labelling, and infrequently (n = 74; 41.4%) used the recommended World Health Organization Front-of-Pack Nutrition Labelling. Product category, origin, and package size were significantly associated with higher levels of international standard adherence (p < 0.05). CONCLUSION: The inadequate adherence to mandatory labelling standards and the scarce use of Swahili and FoPL highlight the need to strengthen labelling practices and potential challenges faced by consumers in understanding nutritional information. Thus, strengthening and emphasizing good labelling practices are urgently needed as we seek to address diet-related noncommunicable diseases.

Food and beverage selection in children's sports arenas in Norway: a cross-sectional study.

OBJECTIVE: To assess the selection of foods and beverages in children's sports arenas in Norway. DESIGN: A cross-sectional study design with a digital questionnaire was used. Descriptive statistics were used to present the results. Moreover, Pearson's χ2 tests examined the factors that could aid in distinguishing clubs with healthy or unhealthy consumables. SETTING: Children's sports clubs in Norway. PARTICIPANTS: Representatives from 301 children's sports clubs in Norway answered the questionnaire between September and November 2021. RESULTS: In total, 89·4% of the participating sports clubs (n 301) offered soda drinks with sugar. Most of the sports clubs (88 %) reported to offer batter-based cakes such as pancakes and waffles and 63·8 % offered cakes. Furthermore, 47·5% sold hot dishes with processed meat, such as hamburgers and hot dogs. More than 80% of the sports clubs offered sweets and snacks, while 44·5% did not offer fruits, vegetables and/or berries. Notably, the important factors that distinguished sports clubs with healthier food selections from those with unhealthier selections were the presence of guidelines for the food offered and purchase agreements with food suppliers. CONCLUSIONS: Educational, governmental guidelines for the promotion of healthy eating and establishing agreements with suppliers of healthier foods could help to overcome barriers to unhealthy food selection.

Correlation between acoustic characteristics and sensory evaluation of puffed-grain food based on energy analysis.

Puffed-grain food is a crispy snack whose consumer satisfaction depends on snack crispness and crunchiness, which can be characterized by the sound and the acoustic signals of food breaking. This study aimed to evaluate whether acoustic characteristics can be used to predict the crispness of various puffed-grain food. Sensory evaluation was performed on puffed-grain products with varying hygroscopic durations and different types. The relation between sensory evaluation and acoustic characteristics of nine different types of food was examined. The Hilbert-Huang transform was used to perform energy segmentation of the acoustic signal of puffed-grain food and observe its energy migration process. The results showed that energy release was more concentrated in the low-frequency range for grain-puffed foods with different hygroscopic durations. No notable correlation was observed between the low-frequency interval and sensory crispness for the different types of puffed-grain foods. However, the acoustic features extracted from their inherent low-frequency intervals showed a significantly improved correlation with sensory crispness. Therefore, it provides a theoretical reference for applying acoustic characteristics to describe food texture.

Novel foods, old issues: Metabarcoding revealed mislabeling in insect-based products sold by e-commerce on the EU market.

Insects intended for human consumption are considered Novel Foods according to EU legislation. marketed in form of powders, bars, snacks are increasingly available on the EU market, especially on e-commerce. The commercial form and the way of distribution make IBPs particularly prone to mislabeling. Literature concerning the mislabeling occurrence in IBPs is extremely scarce. In this study, 46 processed IBPs were collected on nine EU e-commerce platforms (e-CO) to be authenticated by metabarcoding. A 200 bp region from 16S rRNA gene was used as molecular target. Sequencing data were processed using DADA2 R package, and sequences were taxonomically assigned through BLAST analysis against GenBank. Procedural blanks and positive controls were included in the analysis, and threshold values were established to filter the final data. The mislabeling rate (i. e. the mismatch between the species declared on the IBP label and the species identified by metabarcoding) was calculated. Overall, a high mislabeling rate (33.3 %) was observed, although this percentage is influenced by the e-CO platform and the insect species, with A. domesticus particularly involved. The use of species not listed in authorized Novel Food (e. g. Gryllus locorojo), and/or the partial replacement of high value species with lower value species was highlighted for the first time in processed IBPs. The presence of insect pests was also detected. Metabarcoding was confirmed as an effective tool for IBPs authentication. Also, outcomes from this study can provide useful data on the main issues involving the EU IBPs' market, that can represent an incentive to reinforce both official controls and FBO's self-controls on these poorly investigated products.

Diet quality and snack preferences of Turkish adolescents in private and public schools.

Introduction: Socioeconomic level is one of the important factors determining diet quality. Snack preferences are affected by socioeconomic level. The objective of this research was to determine the effect of socioeconomic levels on diet quality and snack preferences among adolescents from different socioeconomic backgrounds. Methods: The study involved 118 adolescents aged between 10-18 years residing in Istanbul. A questionnaire prepared by the researchers was used to obtain information on the adolescents' dietary habits, consumption of main meals and snacks, habits, and food consumption records. The participants' food consumption was assessed using the retrospective 24-hour recall method, and diet quality was evaluated using the calculated nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). Results: The mean age of the adolescents was 16.42±0.89 years. The number of snacks consumed in private schools was found to be higher than in public schools (p < 0.05). The NAR score for vitamin C consumption was significantly higher in private schools compared to public schools (p < 0.05). Although the MAR scores of adolescents in private schools were higher than those in public schools, this difference was not statistically significant. The majority of adolescents in private schools regularly consumed fresh fruit (67.2%), milk (60.3%), yogurt (60.3%), and nuts (56.9%) as snacks. In contrast, 45% of adolescents in public schools regularly consumed pastries (p < 0.05). Discussion: It was observed that adolescents studying in public schools had a lower tendency to prefer healthy foods for snacks compared to those in private schools. Socioeconomic level was identified as an important factor influencing eating habits during adolescence. Considering that the level of income is significantly different between the adolescents studying at private and public schools, the higher consumption of snacks by the adolescents studying at private school may be associated with higher income.

Steaming Maintains Fatty Acids, Antioxidants, and Proximate Content in Snack Bar Products from Cocoa Beans.

Chocolate products on the market are generally in the form of chocolate bars as snacks made from cocoa powder. Fat and powder are separated first through a pressing process to obtain the cocoa powder. Cocoa powder loses most of its fat content during processing. Therefore, the study aimed to determine the effect of steaming time on the cocoa bean content of fatty acids, free fatty acids, proximate levels, and antioxidant activity of snack bar products made from steamed cocoa beans. Seven steaming time intervals for cocoa beans were studied. The results showed that a longer steaming time affects the fatty acids, saturated fatty acids, antioxidants, and proximate in cocoa beans. Steaming time treatment at 45 minutes increased oleic acid, palmitic acid, and antioxidant activity. In addition, reducing free fatty acids represents a quality improvement that meets international Codex Alimentarius standards, offering a competitive advantage in the market. The food industry can adopt this steaming technique to develop snack bars and new products that are healthier and more sustainable by using steaming as an effective processing method in maintaining and increasing the nutritional value of products.

Unit size influences ad libitum intake in a snacking context via eating rate.

Geometric and textural properties of food, like unit size, have previously been shown to influence energy intake. While mechanism(s) driving this effect are unclear, unit size may relate to intake by affecting eating microstructure (e.g., eating rate, bite size). In a randomized crossover study, we investigated relationships between unit size, eating microstructure, and intake. Adults (n = 75, 75% women) consumed an ad libitum snack three times in our laboratory. This snack was a 70-g portion (∼2.5 servings) of one of three sizes of pretzel (small, medium, large). Intake was measured in grams by difference in weight before and after the snack. Each session was video recorded to measure eating microstructure; snack duration (min) and number of bites were annotated and used to calculate mean eating rate (g/min) and mean bite size (g/bite). Results revealed unit size influenced intake (grams and kcal; both p's ≤ 0.001), such that participants consumed 31% and 22% more of the large pretzels (16.9 ± 2.3 g) compared to the small (12.9 ± 2.3 g) and medium sizes (13.8 ± 2.3 g), respectively. Unit size also influenced eating rate and bite size (both p's < 0.001); the largest pretzel size yielded the fastest eating rate and largest mean bite size. Further analysis revealed that after accounting for eating microstructure, the effects of unit size on intake were no longer significant, suggesting eating microstructure was driving these effects. Together, these findings indicate that unit size influences intake by affecting eating microstructure and that food properties like unit size can be leveraged to moderate snack intake.

Self-identified strategies to manage intake of tempting foods: cross-sectional and prospective associations with BMI and snack intake.

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.

Chronic and immediate refined carbohydrate consumption and facial attractiveness.

The Western diet has undergone a massive switch since the second half of the 20th century, with the massive increase of the consumption of refined carbohydrate associated with many adverse health effects. The physiological mechanisms linked to this consumption, such as hyperglycaemia and hyperinsulinemia, may impact non medical traits such as facial attractiveness. To explore this issue, the relationship between facial attractiveness and immediate and chronic refined carbohydrate consumption estimated by glycemic load was studied for 104 French subjects. Facial attractiveness was assessed by opposite sex raters using pictures taken two hours after a controlled breakfast. Chronic consumption was assessed considering three high glycemic risk meals: breakfast, afternoon snacking and between-meal snacking. Immediate consumption of a high glycemic breakfast decreased facial attractiveness for men and women while controlling for several control variables, including energy intake. Chronic refined carbohydrate consumption had different effects on attractiveness depending on the meal and/or the sex. Chronic refined carbohydrate consumption, estimated by the glycemic load, during the three studied meals reduced attractiveness, while a high energy intake increased it. Nevertheless, the effect was reversed for men concerning the afternoon snack, for which a high energy intake reduced attractiveness and a high glycemic load increased it. These effects were maintained when potential confounders for facial attractiveness were controlled such as age, age departure from actual age, masculinity/femininity (perceived and measured), BMI, physical activity, parental home ownership, smoking, couple status, hormonal contraceptive use (for women), and facial hairiness (for men). Results were possibly mediated by an increase in age appearance for women and a decrease in perceived masculinity for men. The physiological differences between the three meals studied and the interpretation of the results from an adaptive/maladaptive point of view in relation to our new dietary environment are discussed.

Effect of a Technology-Integrated Curriculum on Sugary Drink and Snack Intake of Elementary-Aged Youth Experiencing Low Income.

OBJECTIVE: To describe the results of a technology-integrated intervention on sugar-sweetened beverage (SSB) and energy-dense snack intake with third graders experiencing low income. DESIGN: A 2 × 2 quasi-randomized cluster-block, parallel-group experimental research design. SETTING: Low-income schools in Rhode Island. PARTICIPANTS: Two-hundred seventeen intervention and 242 control third-grade students in low-income (89.6% and 88.2% free/reduced meals, respectively), ethnically and racially diverse (63% Hispanic/20% Black and 62% Hispanic/18% Black, respectively) schools. INTERVENTION(S): A 13-week in-school program held once per week for 1 hour. The hands-on, technology-integrated program used a modified version of the Body Quest: Food of the Warrior curriculum. MAIN OUTCOME MEASURE(S): Intake of SSB and energy-dense snacks, both salty and sweet snacks, using baseline (week 1) and postassessment (week 13) previous day self-recall. ANALYSIS: Generalized mixed modeling with nesting. RESULTS: Intervention students significantly reduced their SSB intake by 38% (0.5 times/d; F[1, 540] = 4.26; P = 0.04) and salty snack intake by 58% (0.8 times/d; F[1, 534] = 6.58, P < 0.01) from baseline to postassessment as compared with the control students. CONCLUSIONS AND IMPLICATIONS: Findings suggest a technology-integrated curriculum is effective in decreasing SSB and salty snacks in elementary-aged students of low-income, minoritized populations. Improved dietary habits can potentially influence other facets of students' lives.

Sugar-Sweetened Beverages, Foods of Low Nutritional Value, and Child Undernutrition in Cambodia.

Child undernutrition persists in Cambodia despite recent progress. As Cambodia undergoes a shift in dietary consumption that coincides with economic, demographic, and epidemiologic changes, there is risk of ultra-processed foods and sugar-sweetened beverages displacing nutrient-dense foods during the critical period of infant growth in the first 24 months. The aim of this study was to assess the introduction and intake of foods of low nutritional value and sugar-sweetened beverages and their association with undernutrition among children 24 months of age in rural and semi-urban Cambodia. Cross-sectional analyses of a 24-h dietary recall from a sample (n = 377) of 24-month-olds found that the majority of infants had been introduced to packaged salty snacks and sweets by 12 months of age and to sugar-sweetened beverages by 15 months. By 24 months of age, 78% of children had consumed foods of low nutritional value and 57% consumed a sugar-sweetened beverage on the previous day. Multivariate logistic regression analyses demonstrated that infant intake of a flavored sugary drink on the previous day was associated with over two times the odds of both stunting and wasting, and consumption of packaged sweets on the previous day was associated with over two times the odds of wasting, but no association was found with stunting. These findings underscore the need to improve educational and policy interventions to support healthy feeding practices for infants and young children.

Nutritionally Valuable Components and Heat-Induced Contaminants in Extruded Snack Products Enriched with Defatted Press Cakes.

This research studies the influence of the addition of defatted press cakes (from the production of hazelnut, camelina, pumpkin, and hemp seed oil) on nutritionally important components: fibre, resistant starch, polyphenols, hydroxymethylfurfural (HMF), and acrylamide in directly and indirectly expanded snacks. The amounts of press cakes added to corn grits were 3, 6, and 9%. Extrusion was carried out in a laboratory single-screw extruder. For indirectly expanded products (SCFX), supercritical CO2 was injected during extrusion, and secondary expansion was completed in the microwave oven. The type and content of press cake, as well as the type of product, significantly influenced total polyphenol content and antioxidant activity. Press cakes increased the contents of both soluble and insoluble fibre (from 1.94% d. m. and 1.28% d. m. for extrudates without press cakes up to 3.17% d. m. and 6.94% d. m. for SCFX extrudates with press cakes, respectively), and resistant starch was not markedly influenced by their addition. The influence of the content of press cake on HMF was not significant, whereas the type of cake and the type of extrusion influenced HMF significantly. In a raw mixture of corn grits with 3% of pumpkin press cake, HMF was below the limit of detection, and the highest content was found in the classically extruded sample with the addition of 9% of camelina press cake (580 ppb). In all samples, the acrylamide content was below the limit of detection, indicating that safe products were obtained. This research shows potential for the implementation of supercritical CO2 extrusion in the production of safe, nutritionally improved snack products. Future research might bring about the design of cost-effective processes applicable in the industry.

Timing and Nutrient Type of Isocaloric Snacks Impacted Postprandial Glycemic and Insulinemic Responses of the Subsequent Meal in Healthy Subjects.

The aim of the study was to explore the impact of both the macronutrient composition and snacking timing on the postprandial glycemic insulinemic responses and food intake. Seventeen healthy female volunteers completed the randomized crossover trials. The volunteers were provided a standard breakfast and lunch at 8:00 and 13:00, respectively, and an ad libitum dinner at 18:00. Provided at either 10:30 (midmorning) or 12:30 (preload), the glycemic effects of the three types of 70 kcal snacks, including chicken breast (mid-C and pre-C), apple (mid-A and pre-A), and macadamia nut (mid-M and pre-M), were compared with the non-snack control (CON), evaluated by continuous glucose monitoring (CGM). The mid-M showed increased insulin resistance after lunch compared with CON, while the pre-M did not. The pre-A stabilized the glycemic response in terms of all variability parameters after lunch, while the mid-A had no significant effect on postprandial glucose control. Both the mid-C and pre-C improved the total area under the glucose curve, all glycemic variability parameters, and the insulin resistance within 2 h after lunch compared with CON. The pre-C attained the lowest energy intake at dinner, while the mid-A and the mid-M resulted in the highest. In conclusion, the chicken breast snack effectively stabilized postprandial glycemic excursion and reduced insulin resistance while the macadamia snack did not, regardless of ingestion time. Only as a preload could the apple snack mitigate the glucose response after the subsequent meal.

Allergic Reaction to a Commercially Available Insect Snack Caused by House Cricket (Acheta domesticus) Tropomyosin.

SCOPE: Edible insects contain allergens with potential cross-reactivity to other invertebrates. Here, this study examines IgE-reactive proteins in a house cricket snack (Acheta domesticus) leading to an allergic reaction in a 27-year old man followed by a similar reaction days later after eating shrimps. METHODS AND RESULTS: Prick to prick tests verify the IgE-mediated allergy to crickets and skin prick testing confirms a type I sensitization to house dust mite without any clinical relevance for the patient, and to shrimp extracts, but is negative for several other foods. Serological testing reveals a sensitization to shrimps, shrimp tropomyosin, and house dust mite tropomyosin. IgE-immunodetection shows that the cricket allergic patient is sensitized to two proteins of 45 and >97 kDa using aqueous control cricket extract, but to only one protein at around 45 kDa when using the causative, seasoned insect snack extract. Mass spectrometry data and IgE-inhibition experiments clearly identify this protein belonging to the tropomyosin allergen family. CONCLUSION: This case report suggests that cricket tropomyosin may be an elicitor of allergic reactions even in previously not allergic patients, although it cannot be excluded the patient reacted additionally to other ingredients of the snack.

Associations between everyday exposure to food marketing and hunger and food craving in adults: An ecological momentary assessment study.

Food marketing in television and digital media negatively affects appetitive sensations and eating behaviour in children, but effects are less well understood for outdoor food advertising and adults. This research used Ecological Momentary Assessment (EMA) to explore associations between exposures to food advertising in various contexts (television, digital, outdoors) and adults' hunger and craving for highly advertised food categories. Over one week, participants provided ratings of cravings for types of food (fast food, soft drinks, snacks/confectionery, other) and hunger on a smartphone app up to six times per day when they saw a food advertisement (reactive assessment) and at random intervals (random assessment). Fifty-four participants (70.4 % female; 21.24 ± 3.84 years) provided 1223 assessments (24.7 % reactive, 75.3 % random). Data were analysed in R using multilevel multivariable linear regression models. Participants reported feeling hungrier (X2(1) = 5.85, p = .016, ΔAIC = 3.9) and having stronger cravings (X2(1) = 20.64, p < .001, ΔAIC = 318.6) after seeing food advertisements vs. random assessments. This was driven by greater hunger following television advertising exposure vs. random assessments (ß = 1.58, SE = 0.61, p = .010, 95 %CIs 0.38 to 2.78), food advertising via digital devices or outdoors was not associated with hunger. Participants experienced stronger craving after seeing a food advertisement on television (ß = 0.52, SE = 0.19, p = .006, 95 %CIs 0.15 to 0.89), outdoors (ß = 0.39, SE = 0.12, p < .001, 95 % CIs 0.16 to 0.62) and in digital media (ß = 0.36, SE = 0.14, p = .012, 95 % CIs 0.08 to 0.64), vs. random assessments. Cravings were (largely) specific to the advertised food category. EMA can be effective for assessing food marketing associations in adults. The current study provides evidence that food marketing is associated with hunger and craving in adults, which may, with replication, have implications for public health policy.

Effects of maternal mild hyperglycemia associated with snack intake on offspring metabolism and behavior across the lifespan.

The increasing prevalence of diabetes is of particular concern in women of childbearing age because of the short and long-term consequences of maternal diabetes for the health of the offspring, such as a greater risk of developing metabolic impairments and cognitive deficits. In addition, maternal diet during pregnancy and lactation might contribute to preventing or ameliorating adverse offspring outcomes. Recently, we described that access to snacks exacerbates glucose intolerance in mildly hyperglycemic pregnant dams. Therefore, we hypothesized that these offspring would show greater impairment in metabolic and behavioral outcomes across the lifespan. Neonatal STZ treatment was employed to induce maternal mild hyperglycemia in females. After mating, normo- and hyperglycemic dams were given access either to standard chow or standard show plus snacks. Male and female offspring were evaluated on postnatal days (PND) 30, 90, and 360. Offspring behavior was assessed in the marble burying task, the open-field test, the elevated-plus maze, and sucrose preference. Glucose tolerance and morphometric analyses were also carried out. Maternal hyperglycemia increased body weight and fat deposition only on PND 30, while retroperitoneal fat deposition was reduced in the offspring of snack-fed dams. However, maternal snack intake reduced offspring body weight and length on PND 90. Fasting glucose was increased in females born to hyperglycemic, snack-fed dams on PND 90. Glucose clearance was altered by both maternal conditions in male offspring on PND 30, however, this sex difference was reversed on PND 90, with maternal hyperglycemia impairing glucose clearance only in females. In addition, maternal hyperglycemia reduced anxiety-like behavior in female offspring on PND 30, especially in the offspring of snack-fed dams, while maternal snack intake reduced sucrose preference in both males and females in adulthood. These results suggest that the effects of maternal hyperglycemia during pregnancy and lactation on offspring outcomes were not exacerbated by snack intake. Although additive effects of the two maternal conditions were hypothesized, the absence of such effects could be related to the mild maternal hyperglycemia induced by STZ treatment even when combined with snack intake. While maternal hyperglycemia alone impaired some offspring outcomes, its association with snack intake did not aggravate those impairments but rather resulted in outcomes more similar to those of offspring born to normoglycemic dams. Finally, females were found to be more susceptible to both the effects of maternal hyperglycemia and snack intake on metabolism and behavior.

Effects of sensory combination on crispness and prediction of sensory evaluation value by Gaussian process regression.

Crispness contributes to the pleasantness and enjoyment of eating foods and is popular with people of wide ages in many countries. Hence, a quantitative evaluation method for crispness is required for food companies developing new food products. In this study, the effects of different sensory combinations on crispness were investigated through sensory evaluation, and a Gaussian process regression model was used to predict the evaluation values of crispness. First, four crispness descriptors in Japanese were selected, and sensory evaluations were conducted with ten participants using commercially available snack foods under three different sensory combinations of force, vibration, and sound to confirm the effects of the three senses. An instrumental system also measured force, vibration, and sound for snack foods under the same conditions. The Gaussian process regression model determined the relationship between the sensory and measurement data and predicted the sensory evaluation values from the measurement data. Cross-validation verified that the Gaussian process regression model accurately predicted the food texture evaluation values from the measurement data even in conditions with different sensory components.

Resistance exercise snacks improve muscle mass in female university employees: a prospective, controlled, intervention pilot-study.

Background: Although resistance training (RT) is essential to preserve musculoskeletal fitness and maintain a healthy, independent life into old age, few women perform RT. We investigated whether resistance exercise snacking (RES) could be an efficient training approach for the workplace health promotion (WHP) to minimize barriers for participation and facilitate RT in women in order to improve musculoskeletal fitness. Methods: This pilot-study followed a prospective, controlled intervention design. Female employees with sedentary occupations doing RT on less than 2 days/week before study participation were included. Participants self-selected for either intervention (IG) or control group (CG). While the IG [N = 15, mean age 42.1 (SD = 11.1) years] did 10 min of RES on working days for 12 weeks, the CG [N = 15, mean age 49.9 (SD = 9.7) years] was instructed to maintain their habitual physical activity. Primary endpoint was change in muscle mass. Secondary endpoint was change in maximum isometric strength. Balance, cardiovascular fitness, perceived health, and general life satisfaction was assessed for exploratory purpose. Measurements were taken before and after the intervention. Results: 12 participants of IG and 14 of CG completed the study. Muscle mass improved significantly more in the IG [+0.42 (SD = 0.54) kg] compared to the CG [-0.16 (SD = 0.51) kg] (p = 0.01, ƞ2p = 0.24). Strength did not change significantly between groups. Nevertheless, there was a trend for greater improvements in the IG compared to the CG for trunk extension, trunk flexion, and upper body push but not upper body pull. Regarding exploratory endpoints, no significant between-group changes were found. Despite their poor fitness, both groups perceived their health as good and had high life satisfaction before and after the intervention. Conclusion: RES could be an effective approach for the WHP to promote RT in inactive women with sedentary occupations and improve their muscle mass.

Meal frequency strategies for the management of type 2 diabetes subjects: A systematic review.

BACKGROUND: Effective nutrition management is fundamental in the comprehensive treatment of individuals with type 2 diabetes. Various strategies have been explored in this regard, demonstrating their potential usefulness in improving clinical outcomes. This systematic review aims to assess the impact of meals frequency on the well-being of these patients. METHODS AND FINDINGS: In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, PubMed, Embase, Web of Science, Cochrane Library, and Google Scholar databases were searched until July 10th, 2023. We included studies from the last 10 years in people with type 2 diabetes that had an intervention regarding their meal frequency. The risk of bias was evaluated based on the Cochrane tool according to the type of study. Of 77 retrieval articles, 13 studies matched our inclusion criteria. The primary focus of each study was to evaluate glycemic control as the major outcome. Studies suggest that meal frequency, time-restricted feeding, breakfast skipping, bedtime snacking, and chrononutrition practices all play roles in type 2 diabetes management and risk. CONCLUSIONS: Restricting feeding to 2 to 3 meals per day and practicing time restricted feeding with less than 10 hours of daily food intake promotes weight loss and glycemic control in patients with type 2 diabetes. Aligning food consumption with the body's natural rhythm is beneficial, whereas skipping breakfast disrupts this rhythm. Snacking after evening or waiting 3-4 hours after meal helps control glucose levels, but consuming pre-bedtime snacks do not provide the same benefits. PROSPERO REGISTRATION NUMBER: CRD42023431785.
