ABSTRACT
BACKGROUND: Menarche is a pivotal time in an adolescent's life but can be experienced differently by those with physical disabilities. Parents typically serve as the primary educators and support for their daughters during this time. Little is known about the parent's perspective of their daughter's experience preparing for menarche and learning to manage menses. OBJECTIVE: We sought to understand the parent's perspective of the experience of their daughter with a physical disability around menarche and their preferences for health care provider support. METHODS: Individual semi-structured interviews were conducted with 21 parents of a daughter with a physical disability ages 7-26. Interviews were coded by 2 reviewers using Grounded Theory, with disagreements resolved by consensus. RESULTS: Six themes emerged regarding the parent's perception of the experiences, including 1) variation in emotional responses to menarche, 2) parent's perception of their daughter's experience with menses and menstrual symptoms, 3) cross-section of disability and menstrual management, 4) menstrual management at school, 5) parental knowledge correlating to daughter's preparation for menarche, and 6) desires for health care provider support. CONCLUSIONS: All parents reported that their daughters faced challenges during menarche, ranging from emotional distress to dealing with the inaccessibility of hygiene products. Managing periods at schools was particularly burdensome. Parents who were better educated about what to expect were better able to prepare their daughters, but had difficulties finding informed, supportive providers. Health care providers should provide both anticipatory guidance and holistic, respectful, and equitable options for the management of menstrual symptoms.

This study aims to test the associations of nature contact with multiple dimensions of psychological functioning. A total of 90 university employees were randomly assigned to spend their lunch breaks on (1) a 30-min structured protocol of nature contact and (2) a control group for 10 consecutive weekdays. Psychological distress, psychological well-being, and work-related psychological outcomes were assessed at baseline (T1), the day after the 10-day intervention (T2), and three months after the intervention (T3). Mixed-design analyses of variance (ANOVA) were conducted. Overall, significant intervention effects were found in the structured protocol of nature contact on psychological distress, well-being outcomes, and work engagement (all p < 0.05), whereas the 3-month post-intervention effects were non-significant. Our study showed that nature-based activities during lunch breaks could enhance office workers' mental health in general, but the effects could be short-lived, calling for regular nature-based programs in occupational settings.

BACKGROUND: Geriatric medical patients are often at nutritional risk when admitted to hospital. More flexible meal service concepts may prove successful in improving nutritional intake. AIM: To evaluate whether the Free Choice Menu (FCM), a new room service resembling meal service concept, improves energy and protein intake in a population of geriatric medical patients compared with the traditional concept of serving meals from a trolley with a fixed menu (trolley). METHODS: Data were collected consecutive in a geriatric ward at Slagelse Hospital (Denmark) before (autumn 2018; n = 98) and after (autumn 2020; n = 52) implementing the Free Choice Menu. Weighed dietary intake was recorded for three full days for each patient. RESULTS: Energy and protein intake did not differ significantly when comparing the two meal service concepts (trolley: 6124 kJ; 52.6 g and FCM: 5923 kJ; 47.1 g) over three days. The FCM concept showed however a significantly higher energy and protein intake for the dinner (relative to the other meals), whereas a higher percentage of protein and energy intake was covered by oral nutritional supplements in the trolley concept. The majority of the participants met the recommendations for energy intake, while only a minority met the recommendations for protein intake. Plate waste was significantly lower (p = 0.0005) at the lunch meal for the FCM concept (15.6%) compared with the trolley concept (26.1%). CONCLUSION: When implementing a FCM, energy and protein intake was maintained and patients received more energy and protein from the dinner and less from oral nutritional supplements. However, the introduction of a free choice of meals concept did not in itself ensure nutritional intake in geriatric medical patients.

Wellness in the Schools (WITS) is a national non-profit organization partnering with public schools to provide healthy, scratch cooked, less processed meals (called an Alternative Menu), and active recess. This study examined the effects of WITS programming on school lunch consumption, including fruit and vegetable intake, in second and third grade students in New York City public schools serving a high proportion of students from low-income households. The intervention was evaluated with a quasi-experimental, controlled design with 14 elementary schools (7 that had initiated WITS programming in fall 2015 and were designated as intervention schools, and 7 matched Control schools). School lunch consumption was assessed by anonymous observation using the System of Observational Cafeteria Assessment of Foods Eaten (SOCAFE) tool in the fall of 2015 (Time 0, early intervention) and the spring of 2016 (Time 1) and 2017 (Time 2). There were no baseline data. Data were also collected on the types of entrées served in the months of October, January, and April during the two school years of the study. Across time points, and relative to students in the Control schools, students in WITS schools ate more fruits and vegetables (units = cups): Time 0: Control 0.18 vs. WITS 0.28; Time 1: Control 0.25 vs. WITS 0.31; and Time 2: Control 0.19 vs. WITS 0.27; p < 0.001. They also had more fruits and vegetables (cups) on their trays, which included more vegetables from the salad bar. However, students in the WITS schools ate fewer entrées (grain and protein) and drank less milk than students in the Control schools. Compared to the Control schools, WITS schools offered more homestyle entrées and fewer finger foods and sandwich entrees, i.e., less processed food. Students in WITS schools who received the Alternative menu and all of the WITS programming at all data collection time points selected and consumed more fruits and vegetables. Replication studies with randomized designs and true baseline data are needed to confirm these findings and to identify avenues for strengthening the effects of the program on other school lunch components.

Ageing is associated with changes in feeding behavior. We have reported that there is suppression of energy intake three hours after whey protein drink ingestion in young, but not older, men. This study aimed to determine these effects over a time period of 9 h. Fifteen younger (27 ± 1 years, 25.8 ± 0.7 kg/m2) and 15 older (75 ± 2 years, 26.6 ± 0.8 kg/m2) healthy men were studied on three occasions on which they received, in a randomized order, a 30 g/120 kcal, 70 g/280 kcal whey-protein, or control (~2 kcal) drink. Ad-libitum energy intake (sum of breakfast, lunch, and dinner) was suppressed in a protein load responsive fashion (P = 0.001). Suppression was minimal at breakfast, substantial at lunch (~-16%, P = 0.001), no longer present by dinner, and was less in older than younger men (-3 ± 4% vs. -8 ± 4%, P = 0.027). Cumulative protein intake was increased in the younger and older men (+20% and +42%, P < 0.001). Visual analogue scale ratings of fullness were higher and desire to eat and prospective food consumption were lower after protein vs. control, and these effects were smaller in older vs. younger men (interaction effect P < 0.05). These findings support the use of whey-protein drink supplements in older people who aim to increase their protein intake without decreasing their overall energy intake.

The objective of the NEKST (Nutrition Environmental Kibbutzim Study), a nonrandomized interventional study, was to evaluate the effect of an integrated intervention program on participants' lunch quality and diversity in two communal dining rooms (intervention n = 58 vs. control n = 54). The intervention included recipe modification, environmental changes, and an education program. The outcomes included simple healthy meal index (SHMI), lunch quality (LQS), and diversity scores (LDS) calculated based on photographs of lunch trays. A nutrition questionnaire assessed the changes in fruit and vegetable intake at baseline and 3 months following the intervention. The mean SHMI, LQS, and LDS increased in the intervention group (0.51, p < 0.001; 0.27, p = 0.045; 0.95, p < 0.001, respectively) but not in the control group (p = 0.865; p = 0.339; p = 0.354, respectively). Multivariable linear models demonstrate an increase in the SHMI (ß = 0.26, 95% CI [0.12-0.76], p = 0.015), LQS (ß = 0.23, 95% CI [0.06-0.83], p = 0.024), and LDS (ß = 0.34, 95% CI [0.41-1.39], p < 0.001) of the participants in the intervention group. More participants in the intervention group raised their daily fruit intake compared with the control. We conclude that this integrated intervention program was effective in improving lunch healthy meal index, quality, and diversity in a communal dining room, with a modest halo effect of the intervention throughout the day.

This research analyses the effects of mindfulness meditation (MM) and physical exercise (PE), practised as daily recovery activities during lunch breaks, on perceived stress, general mental health, and immunoglobin A (IgA). A three-armed randomized controlled trial with 94 employees was conducted for five weeks including two follow-up sessions after one and six months. Daily practice lasted 30 min maximum. Perceived stress and general mental health questionnaires and saliva samples were used. There were significant differences in time factor comparing pre- and post-test of Perceived Stress Questionnaire (PSQ) both for PE [Mdiff = 0.10, SE = 0.03, p = 0.03], and for MM [Mdiff = 0.09, SE = 0.03, p = 0.03]. Moreover, there were significant differences of interaction factor when comparing MM vs. PE in total score at pre-post [F = -2.62 (6, 168.84), p = 0.02, ω2 = 0.09], favoring PE with medium and high effect sizes. Regarding General Health Questionnaire (GHQ) variable, practicing MM showed significant effects in time factor compared to pre-Fup2. No significant differences were found for IgA. Thus, practicing both MM and PE as recovery strategies during lunch breaks could reduce perceived stress after five weeks of practice, with better results for PE. Moreover, practicing MM could improve mental health with effects for 6 months.

OBJECTIVE: To explore factors that minimize lunch waste in Tokyo elementary schools and to consider how such factors can be modified and applied in US schools. DESIGN: Focused ethnographic study using interviews, observation, participant observation and document review. Data were analysed using thematic analysis. SETTING: Tokyo, Japan. PARTICIPANTS: Five school dietitians participated in the study. Data collection methods included in-depth interviews, observation of nutrition education lessons, participant observation of school lunchtime and review of relevant school documents (e.g. lunch menus, food waste records). RESULTS: Five themes emerged from the analysis: (i) reinforcement of social norms to eat without waste; (ii) menu planning to increase exposure to unfamiliar and/or disliked foods; (iii) integration of food and nutrition education into the school curriculum; (iv) teacher lunchtime practices related to portion sizes, distributing leftover food and time management; and (v) engagement of students in reducing school lunch waste. Practical and tangible applications to US schools include measuring and reporting lunch waste to influence social norms, teaching students about the importance of reducing food waste, offering flexible school lunch portion sizes and providing students with meaningful opportunities to contribute to solving the problem of school lunch waste. CONCLUSIONS: Japan offers a model for minimizing school lunch waste through a holistic approach that includes factors that operate at and interact across multiple levels of society. Modifying and applying such an approach in US schools is worth considering given the urgent need to address food waste in order to support healthy diets and sustainable food systems.

Acrylamide (AA) is a food process contaminant with carcinogenic and genotoxic properties that is formed in thermally treated foods, especially carbohydrate-rich. Dietary exposure to AA, due to school canteen foods, was estimated in schoolchildren aged 3-13 years by combining the AA concentration in foods with the amount and frequency of food consumption. Potato products and bakery products presented the highest mean levels of AA (841 and 244 µg/kg, respectively) followed by meat (222 µg/kg) and egg products (151 µg/kg). The mean total AA intake was estimated at 2.16 µg/kg bw/d, with the highest percentages provided by potato products (34.5%), meat products (26.1%) and bread (24.5%). The calculated margins of exposure (MOEs) for the average AA exposure (84 and 212 for the benchmark dose lower confidence limits (BMDL) of 0.17 and 0.43 mg/kg bw/d) suggest that there is a health concern with respect to students eating in school canteens.

This study examined the effects of a key feature of mindful eating (paying attention to the sensory properties of food) on calorie and macronutrient intake over a half-day period. Female participants (nâ¯=â¯60) were given a 635â¯kcal lunch of sandwiches, crisps and grapes. Those allocated to an experimental condition were asked to attend to the sensory properties of the food. After lunch, all participants were given 908â¯kcal of three energy dense sweet snack foods and asked to taste and rate them on several dimensions. Unknown to participants, the amounts of all foods consumed were recorded. Before they left the laboratory, participants in the experimental group were also asked to continue to pay attention to the sensory properties of their food for the rest of the day. At the end of the day all participants logged onto a website where they completed a suspicion probe and surprise online food recall measure to assess food intake outside the laboratory. Data from participants who guessed their eating was being measured were excluded. There were no differences between the experimental and control groups in terms of calories consumed during the taste test (166 versus 144â¯kcal respectively; nâ¯=â¯48) or across the entire half-day period (1456 versus 1343â¯kcal respectively; nâ¯=â¯44). There were also no differences in total intake of saturated fat, added sugar or fibre. The results fail to support other research that has shown reductions in food intake following mindful eating. This highlights the need to identify underlying mechanisms of action to better understand when this strategy is, and is not, likely to influence diet. PRE-REGISTRATION: osf.io/f4x2m.

Non-nutritive sweeteners (NNS) are suggested to lower energy intake in the diet, but they have been paradoxically involved in the epidemic of obesity and Type 2 diabetes. Stevia is the least studied sweetener. This study aims to investigate the effect of stevia on postprandial glucose levels, appetite and food intake. METHODS: 30 participants (20 females/10 males; 26.1 (10.56) years; body mass index (BMI) 23.44 (3.42) Kg/m2) took part in a three-arm crossover trial where they received preloads of water, sugar (60 g) and stevia (1 g) on three different days, followed by an ad libitum pizza lunch. Breakfast was standardised. A one-day diet diary was collected on each test day. Visual analogue scales (VAS) were used to assess subjective feelings of appetite. Blood glucose samples were collected at 30-min intervals until 120 min post lunch. RESULTS: Energy intake did not significantly differ between preloads for ad libitum meals (p = 0.78) and overall day (p = 0.33). VAS scores for hunger and desire to eat (DTE) were lower following stevia preload compared to water (p < 0.05). After adjusting for the sugar preload and calorie content, postprandial glucose levels did not significantly differ between interventions. CONCLUSION: Stevia lowers appetite sensation and does not further increase food intake and postprandial glucose levels. It could be a useful strategy in obesity and diabetes prevention and management.

Health messages may be an important predictor in the selection of healthier food choices among young adults. The primary objective of our study is to test the impact of labeling whole grain pasta with a health message descriptor displayed at the point-of-purchase (POP) on consumer choice in a campus dining setting. The study was conducted in a large US college dining venue during lunch service; data were collected during a nine-week period, for a total of 18 days of observation. Each day, an information treatment (i.e., no-message condition; vitamin message; fiber message) was alternated assigned to whole grain penne. Over the study period, the selection of four pasta options (white penne, whole grain penne, spinach fettuccine, and tortellini) were recorded and compiled for analysis. Logistic regression and pairwise comparison analyses were performed to estimate the impact of health messages on diners' decisions to choose whole grain penne among the four pasta types. Our results indicate that only the message about vitamin benefits had a significant effect on this choice, with a 7.4% higher probability of selecting this pasta than the no-message condition and 6.0% higher than the fiber message condition. These findings suggest that psychological health claims (e.g., reduction of fatigue) of whole grains seem more attractive than physiological health claims (e.g., maintaining a healthy weight) for university students. In line with the 2015-2020 Dietary Guidelines for Americans, our results suggest that small changes made at the POP have the potential to contribute to significant improvements in diet (e.g., achieving recommended levels of dietary fiber). These findings have important implications for food service practitioners in delivering information with the greatest impact on healthy food choices.

El propósito de este estudio fue analizar los cambios post prandiales en el perfil lipídico en respuesta a una comida típica argentina. Se extrajo sangre a 33 mujeres voluntarias después de 12 h de ayuno (T0), 1 h después de un desayuno estandarizado (T1) y 1 h después de un almuerzo estandarizado (T2). Se midieron los niveles de: colesterol total, colesterol de lipoproteínas de alta densidad (C-HDL), colesterol de lipoproteínas de baja densidad (C-LDL) y triglicéridos. Los datos se analizaron utilizando la prueba t de Student pareada. Para cada analito se calculó la diferencia porcentual media (DM%) en T1 y T2 respecto de T0 y se comparó con el valor de referencia del cambio (VRC). Las DM% mayores al VRC se consideraron clínicamente significativas. En T1 y T2, los valores de C-HDL fueron más bajos que en T0, mientras que los valores de C-LDL en T1 fueron más bajos que en T0. Los niveles de triglicéridos fueron significativamente más altos en T1 que en T0. En todos los casos, la variabilidad fue estadísticamente significativa, aunque no clínicamente. En este estudio puede observarse que el perfil de lípidos en T1 y T2 no mostró diferencias clínicamente significativas con respecto a los valores basales.
The purpose of the present study was to analyze postprandial lipid profile changes in response to a typical Argentine meal. Blood was collected from 33 female volunteers after a 12 h fasting period (T0), 1 h after a standardized breakfast (T1) and 1 h after a standardized lunch (T2). The levels of total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides were measured. Data were analyzed using paired Student's t-test. Mean difference % (MD %) was calculated for each analyte at T1 and T2 and was further compared with reference change value (RCV). MDs % higher than RCV were considered clinically significant. At T1 and T2, HDL-C values were lower than at T0, whereas LDL-C values at T1 were lower than at T0. Triglycerides levels were significantly higher at T1 than baseline values. In all cases, variability was statistically, though not clinically, significant. This study demonstrates that at T1 and T2 lipid profile showed no clinically significant differences with respect to basal values.

BACKGROUND: Household air pollution from combustion of solid fuels for cooking and space heating is one of the most important risk factors of the global burden of disease. This study was aimed to determine the association between household air pollution due to combustion of biomass fuel in Sri Lankan households and self-reported respiratory symptoms in children under 5 years. METHODS: A prospective study was conducted in the Ragama Medical Officer of Health area in Sri Lanka. Children under 5 years were followed up for 12 months. Data on respiratory symptoms were extracted from a symptom diary. Socioeconomic data and the main fuel type used for cooking were recorded. Air quality measurements were taken during the preparation of the lunch meal over a 2-h period in a subsample of households. RESULTS: Two hundred and sixty two children were followed up. The incidence of infection induced asthma (RR = 1.77, 95%CI;1.098-2.949) was significantly higher among children resident in households using biomass fuel and kerosene (considered as the high exposure group) as compared to children resident in households using Liquefied Petroleum Gas (LPG) or electricity for cooking (considered as the low exposure group), after adjusting for confounders. Maternal education was significantly associated with the incidence of infection induced asthma after controlling for other factors including exposure status. The incidence of asthma among male children was significantly higher than in female children (RR = 1.17; 95% CI 1.01-1.37). Having an industry causing air pollution near the home and cooking inside the living area were significant risk factors of rhinitis (RR = 1.39 and 2.67, respectively) while spending less time on cooking was a protective factor (RR = 0.81). Houses which used biomass fuel had significantly higher concentrations of carbon monoxide (CO) (mean 2.77 ppm vs 1.44 ppm) and particulate matter2.5 (PM2.5) (mean 1.09 mg/m3 vs 0.30 mg/m3) as compared to houses using LPG or electricity for cooking. CONCLUSION: The CO and PM2.5 concentrations were significantly higher in households using biomass fuel for cooking. There was a 1.6 times higher risk of infection induced asthma (IIA) among children of the high exposure group as compared to children of the low exposure group, after controlling for other factors. Maternal education was significantly associated with the incidence of IIA after controlling for exposure status and other variables.

Emerging evidence suggests a link between young people's interest in alternative food production practices and dietary quality. The primary purpose of this study was to examine the impact of a student-driven sustainable food systems education and promotion intervention on adolescent school lunch selection, consumption, and waste behaviors. Sixth grade science teachers at two middle schools (n = 268 students) implemented a standards-based curriculum on sustainable food systems, addressing the environmental impacts of food choices and food waste. The cumulating curriculum activity required the 6th grade students to share their food systems knowledge with their 7th and 8th grade counterparts (n = 426) through a cafeteria promotional campaign to discourage food waste. School-wide monthly plate waste assessments were used to evaluate changes in vegetable consumption and overall plate waste using a previously validated digital photography method. At baseline, the intervention students consumed significantly less vegetables relative to the control group (47.1% and 71.8% of vegetables selected, respectively (p = 0.006). This disparity was eliminated after the intervention with the intervention group consuming 69.4% and the control consuming 68.1% of selected vegetables (p = 0.848). At five months follow up, the intervention group wasted significantly less salad bar vegetables compared to the control group (24.2 g and 50.1 g respectively (p = 0.029). These findings suggest that food systems education can be used to promote improved dietary behaviors among adolescent youth.

Eight in ten female readymade garment (RMG) workers in Bangladesh suffer from anemia, a condition which damages both health and productivity. This study evaluated the effectiveness of a workplace nutrition program on anemia reduction in female RMG workers of Bangladesh. A quasi-experimental mixed method study was conducted on 1310 non-pregnant female RMG workers from four factories. Two types of intervention packages (A and C) were tested against their respective controls (B and D) over a 10-month period. Among factories that already provided lunch to workers with regular behavior change counseling (BCC), one intervention (A) and one control (B) factory were selected, and among factories that did not provide lunches to their workers but provided regular BCC, one intervention (C) and one control (D) factory were selected: (A) Lunch meal intervention package: daily nutritionally-enhanced (with fortified rice) hot lunch, once weekly iron-folic acid (IFA) supplement and monthly enhanced (with nutrition module) behavior change counseling (BCC) versus (B) Lunch meal control package: regular lunch and BCC; and (C) Non-meal intervention package: twice-weekly IFA and enhanced BCC versus (D) Non-meal control package: BCC alone. Body weight and capillary hemoglobin were measured. Changes in anemia prevalence were estimated by difference-in-difference (DID) method. Thematic analysis of qualitative in-depth interviews with RMG workers was performed and findings were triangulated. Anemia was reduced significantly in both lunch meal and non-meal intervention (A and C) group (DID: 32 and 12 percentage points, p: <0.001 and <0.05 respectively). The mean hemoglobin concentration also significantly increased by 1 gm/dL and 0.4 gm/dL in both A and C group (p: <0.001 respectively). Weight did not change in the intervention groups (A and C) but significantly increased by more than 1.5 kg in the comparison groups (B and D). The knowledge of different vitamin and mineral containing foods and their benefits was increased significantly among all participants. Workplace nutrition programs can reduce anemia in female RMG workers, with the greatest benefits observed when both nutritionally enhanced lunches and IFA supplements are provided.

Numerous governments in developing countries institute school lunch programs or school feeding programs as a strategy to address high malnutrition and low education rates among children. In 2005, the Ghanaian government launched the Ghana School Feeding Programme (GSFP). The GSFP policy does not document (1) the actual meal and associated nutrient profile received by the student, (2) the cost of the meal ingredients to the caterer who prepares the food, nor (3) the recipe derivations that may supply an enhanced nutritional profile. We address these 3 information gaps by employing a detailed case study of 4 caterers supplying a traditional tomato stew recipe in northern Ghana within GSFP-supported school lunch programs. Specifically, we explore the following propositions: (1) GSFP caterers can deliver a school lunch for under 100 pesewas (1 GH¢ or $0.21 USD) per student; (2) the meal meets the recommended daily allowance for protein; (3) soy can serve as a cost-effective ingredient to fortify the meal in terms of protein level and protein quality; and (4) significant differences exist in the macro- and micronutrient profile due to caterer discretion. We answer the above 4 propositions, and by doing so show the importance of accurately measuring the nutritional content, costs, and quantities of the actual school lunch under study. Second, among our results, we show the economy of locally produced soy flour as an ingredient that can lower costs and raise nutrition when substituting for other locally produced proteins such as ground beef and mackerel.

BACKGROUND: Pressure to improve school meals has resulted in stringent nutritional guidelines across the UK. In Wales, the 'Appetite for Life' guidelines of 2008 resulted in significant changes to the provision of food in Welsh schools. Although evaluation of these changes has focussed on nutritional quality, there is little evidence of how pupils perceive these changes and their impact on school food practices. Using a Collective Lifestyles approach, the present study reports how secondary school pupils perceive and negotiate menu changes and the implications for lunchtime practices. METHODS: Seven focus groups (52 pupils) were undertaken in four secondary schools within one local authority in Wales. Participatory techniques were used to facilitate discussion, and the focus groups were recorded, transcribed and analysed using a framework approach. Analysis was underpinned by a Collective Lifestyles approach, which provides a framework to understand behaviour in context using three domains: (i) patterns of consumption; (ii) the construction and maintenance of identity; and (iii) power relationships. RESULTS: Pupils reported that the new menus were unpopular in terms of content and meal type; the preference was for portable and snack style foods. In terms of power relationships, pupils' ability to negotiate within the school setting was constrained by the institutional nature of school dining. As a result, pupils tended to opt out of school food provision, accessing alternatives where possible. CONCLUSIONS: The development of the healthy eating agenda within the school setting needs to consider the complexities of adolescent consumption preferences, identities and social networks if they are to be successful.

Cognitive functioning and academic performance of pupils depend on regular breaks from classroom work. However, it is unclear which settings during such breaks provide the best environment to restore cognitive performance and promote wellbeing of adolescent pupils. Therefore, we investigated the effects of staying in different urban green spaces during breaks. Sixty-four pupils (16â»18 years old) participated in a cross-over experiment. They were placed into one of three settings (small park, larger park, forest) for one hour during a lunch break. Wellbeing was assessed four times (Nitsch scale), and a cognitive test (d2-R Test of Attention) was applied in the classrooms before and after the break. Wellbeing was almost always highest after the stay in the green spaces. However, a sustained effect was only found for the forest. Concentration performance values of the d2-R test were significantly higher after the pupils’ stay in green spaces for all sites. The highest increase of performance was found for the larger park type. In conclusion, this pilot study showed that study breaks in green spaces improved wellbeing and cognitive performance of adolescents. It also found that larger green spaces, either parks or forests, have stronger positive impacts on wellbeing and cognitive performance than small parks.

Background: Large doses of whey protein consumed as a preload before single high-glycemic load meals has been shown to improve postprandial glycemia in type 2 diabetes. It is unclear if this effect remains with smaller doses of whey co-ingested at consecutive mixed-macronutrient meals. Moreover, whether hydrolyzed whey offers further benefit under these conditions is unclear. Objective: The aim of this study was to investigate postprandial glycemic and appetite responses after small doses of intact and hydrolyzed whey protein co-ingested with mixed-nutrient breakfast and lunch meals in men with type 2 diabetes. Design: In a randomized, single-blind crossover design, 11 men with type 2 diabetes [mean ± SD age: 54.9 ± 2.3 y; glycated hemoglobin: 6.8% ± 0.3% (51.3 ± 3.4 mmol/mol)] attended the laboratory on 3 mornings and consumed 1) intact whey protein (15 g), 2) hydrolyzed whey protein (15 g), or 3) placebo (control) immediately before mixed-macronutrient breakfast and lunch meals, separated by 3 h. Blood samples were collected periodically and were processed for insulin, intact glucagon-like peptide 1 (GLP-1), gastric inhibitory polypeptide (GIP), leptin, peptide tyrosine tyrosine (PYY3-36), and amino acid concentrations. Interstitial glucose was measured during and for 24 h after each trial. Subjective appetite was assessed with the use of visual analog scales. Results: Total postprandial glycemia area under the curve was reduced by 13% ± 3% after breakfast following the intact whey protein when compared with control (P < 0.05). Hydrolyzed whey attenuated early glucose after breakfast when compared with control (P < 0.05). Glycemia was improved postlunch after the intact whey protein only when compared with control (P < 0.05). Greater satiety was observed after the intact whey protein only after both meals when compared with control (P < 0.05). Insulin concentrations increased after both the intact and hydrolyzed whey protein, showing strong positive correlations with increases in valine and isoleucine (P < 0.05). Incretin and appetite regulatory hormone responses were similar across trials (P > 0.05). Conclusions: The consumption of a small 15-g dose of intact whey protein immediately before consecutive mixed-macronutrient meals improves postprandial glycemia, stimulates insulin release, and increases satiety in men with type 2 diabetes.
