Promoting a sustainable diet among office workers in Sweden: A pilot Study

Abstract Background Society is facing multiple challenges, including lifestyle-related diseases, alongside global climate change. Actions are needed to promote sustainable lifestyles advocating for healthy and environmentally friendly diets. This study aimed to assess how a sustainable lifestyle, compared to conventional healthy lifestyle education at work, affects participants’ energy intake, nutrient consumption, and diet-related CO2e. Methods An 8 week two-armed randomized trial was conducted, comprising a sustainable lifestyle arm (n = 21) and a healthy lifestyle arm (n = 16) based on the theoretical framework of the Behavioral Change Wheel, in total (n = 33) completed the trial. The office workers participated in 6 workshops during working hours. Linear mixed-effects models and analysis of variance tests were used for data analysis. Changes over time are presented as arms combined, along with their respective mean differences. Results A significant decrease in mean diet-related CO2e was observed (p < 0.001), with a decrease on average of 0.74 and 0.71 kg CO2e/day. The mean change in daily kilocalorie intake had a significant decrease over time (p = 0.008), on average of 192 and 386 Kcal. Moreover, a significant decrease in mean protein intake was observed (p < 0.001), with a decrease on average of 16 and 18 grams, possibly explaining the decrease in CO2e. No significant differences were observed between the arms at any timepoint. Conclusions Promoting sustainable lifestyle habits has a similar impact to advocating for a conventional healthy lifestyle regarding diet. This supports the new Nordic Nutrition Recommendations 2023. Despite the small sample size, insights into facilitating sustainable behaviors can influence public health policies across Europe and the workplace as an arena for health promotion. Key messages • The promotion of sustainable and healthy lifestyle habits at work can promote both individual and planetary health by decreasing diet-related CO2e emissions. • Here we demonstrate that the workplace has the potential to act as an arena to combat climate change.

Protein intake by master swimmers: Implications for practice in Sports Nutrition-A cross-sectional study.

Background: Proteins are essential for the maintenance, repair, and growth of muscle mass. This is particularly important for master athletes because aging has been associated with loss of muscle mass, function, and strength. Moreover, the timing of intake has been shown important for the best protein utilization. Aim: To analyze timing, quantity, and source of dietary protein in competitive master athletes according to current recommendations. Methods: Twenty-one male master swimmers (47.9 ± 10.0 years; 79.2 ± 6.5 kg; 179.1 ± 5.5 cm; 23.5 ± 4.9% body fat; 73.3 ± 4.2% lean mass) participated in this cross-sectional study. Protein intake was analyzed based on 7-day food records, regarding quantity, timing, and sources of intake. Protein intake was evaluated according to current international sports nutrition guidelines, including the International Society of Sports Nutrition Position Stand. Body fat (%) and lean mass (%) were evaluated using dual-energy X-ray absorptiometry. Results: Participants' mean protein intakes were 1.9 ± 0.5 g/kg/day, 0.6 ± 0.2 g/kg/meal post-training, and 33.5 ± 23.9 g during the pre-sleep period. Daily intake was within the recommended values of 1.4 and 2.0 g/kg/day (p = 0.01 and 0.147, respectively). Mean pre-sleep intake was within the recommendation values of 30-40 g (p = 0.28 and 0.147, respectively). Most of the daily protein intake was consumed at lunch (66.7 ± 6.9 g) and dinner (48.0 ± 4.5 g). Regarding protein sources, intakes from animal, vegetal, and supplements were, respectively, 65.7%, 29.2%, and 5.1%. Conclusion: Master swimmers presented a total protein intake within the recommendations for a daily basis, but the majority of intake was at lunch and dinner. Protein intake could be better distributed throughout the day to optimize protein synthesis. Guidance on daily protein intake distribution should be reinforced in clinical practice.

Association between objectively measured protein intake and muscle status, health-related quality of life, and mortality in hemodialysis patients

Protein intake is known to be associated with muscle mass, health-related quality of life (HRQoL), and mortality in patients with stage 5 chronic kidney disease undergoing dialysis. However, most studies evaluated protein intake based on 24h dietary recall or food frequency questionnaire, and these methods are prone to bias. Therefore, this study aimed to evaluate the association of objectively measured protein intake with muscle mass and strength, HRQoL, and mortality. Dietary protein intake was calculated based on the combined (urinary and dialysate) urea excretion rate according to the Maroni formula and indexed to body weight. Muscle mass was calculated based on the combined dialysate and urinary creatinine excretion rate, and muscle strength was assessed by handgrip strength. HRQoL was based on the Short Form 36. Linear and Cox regression were used for the analyses. We included 59 hemodialysis patients (mean age 65±15 years, 37% female, median hemodialysis vintage 15 [6-39] months). Mean protein intake was 0.82±0.23g/kg/day, and 76% had a low protein intake (<1.0g/kg/day). Higher protein intake was independently associated with higher muscle mass (Standardized beta (St. β) [95% confidence interval (95%CI)=0.56 [0.34 to 0.78]) and higher scores on the physical functioning domain of HRQoL (St. β [95%CI]=0.49 [0.25 to 0.73]), but not with muscle strength (St. β [95%CI]=0.17 [-0.10 to 0.43]). During a median follow-up of 21.6 [8.6-36.6] months, 16 (27.1%) patients died. Higher protein intake was associated with lower mortality risk (hazard ratio [95%CI]=0.34 [0.16-0.73]). This association remained significant after adjustment for potential confounders. Protein intake is independently associated with muscle mass, physical functioning domain of HRQOL, and mortality. Clinicians and dietitians should closely monitor the protein intake of hemodialysis patients.

Dietary Assessment of Tuberculosis Patients Receiving Treatment at a Tertiary Care Center in New Delhi

Introduction: Undernutrition and tuberculosis (TB) are interrelated, with a bidirectional relationship. Despite its potential impact on nutritional status and TB patient outcomes, there is limited information available on the dietary patterns of TB patients in the Indian TB program. This study aims to address this knowledge gap by evaluating dietary patterns and factors associated with reduced dietary intake among TB patients in a tertiary care center. Methodology: This was a cross-sectional study conducted in a directly observed treatment short center working under the National Tuberculosis Elimination Program. A semi-structured, pretested interviewer-administered questionnaire was used to collect data related to the demographic profile and dietary patterns of 49 patients. Results: The mean calorie intake among the patients was 1525.2 (±897) kcal, whereas the required mean calorie intake was 2231.6 (±409.2) kcal. The mean protein requirement was 66.9 (±15.2) g, whereas the mean protein intake was only 39.2 (±15.4) g. Conclusion: To strive toward the goal of TB elimination in India, the nutritional care of the patient cannot be undermined. The need of the hour is to enforce the nutritional supplementation as well as support program by the government at the national level.

Dynamic assessment of prealbumin for nutrition support effectiveness in critically ill patients

Background & AimsSerum prealbumin is considered to be a sensitive predictor of clinical outcomes and a quality marker for nutrition support. However, its susceptibility to inflammation restricts its usage in critically ill patients according to current guidelines. We assessed the performance of the initial value of prealbumin and dynamic changes for predicting the ICU mortality and the effectiveness of nutrition support in critically ill patients. MethodsThis monocentric study included patients admitted to the ICU between 2009-2016, having at least one initial prealbumin value available. Prospectively recorded data were extracted from the electronic ICU charts. We used both univariable and multivariable logistic regressions to estimate the performance of prealbumin for the prediction of ICU mortality. Additionally, the association between prealbumin dynamic changes and nutrition support was assessed via a multivariable linear mixed-effects model and multivariable linear regression. Performing subgroup analysis assisted in identifying patients for whom prealbumin dynamic assessment holds specific relevance. ResultsWe included 3136 patients with a total of 4942 prealbumin levels available. Both prealbumin measured at ICU admission (adjusted odds-ratio (aOR) 0.04, confidence interval (CI) 95% 0.01-0.23) and its change over the first week (aOR 0.02, CI95 0.00-0.19) were negatively associated with ICU mortality. Throughout the entire ICU stay, prealbumin dynamic changes were associated with both cumulative energy (estimate: 33.2, standard error (SE) 0.001, p < 0.01) and protein intakes (1.39, SE 0.001, p<0.01). During the first week of stay, prealbumin change was independently associated with mean energy (6.03e-04, SE 2.32e-04, p<0.01) and protein intakes (1.97e-02, SE 5.91e-03, p<0.01). Notably, the association between prealbumin and energy intake was strongest among older or malnourished patients, those suffering from increased inflammation and those with high disease severity. Finally, prealbumin changes were associated with a positive mean nitrogen balance at day 7 only in patients with SOFA<4 (p=0.047). ConclusionPrealbumin measured at ICU admission and its change during the first-week serve as an accurate predictor of ICU mortality. Prealbumin dynamic assessment may be a reliable tool to estimate the effectiveness of nutrition support in the ICU, especially among high-risk patients.

Nutrition Status, Perspective and Usage of Traditional and Complementary Medicine among Cancer Patients in Malaysia: A Descriptive Study

Cancer sufferers typically seek a rapid alternative remedy, such as traditional and complementary medicine (TCM). Reliable data on the prevalence and patterns of TCM usage in cancer patients is essential for analyzing its implications for oncological treatment and establishing evidence-based research concepts with the possibility for TCM ongoing education and regulation. This study aimed to determine the prevalence and type of TCM as well as to explore patients' perspectives on TCM and nutrition status among cancer patients in Malaysia. A cross-sectional study was conducted at Institut Kanser Negara and Hospital Kuala Lumpur. The validated Malaysian Breast Cancer Survivorship Cohort (MyBCC) questionnaire and most recent medical record was used. Subjects were followed up after a month to obtain anthropometric data and nutritional intake. A total of 382 qualified patients with a median age of 51.38±11.73 years and 76.7% female were recruited. Ethnicity (p&lt;0.001), type of cancer (p=0.04), working status (p=0.015), and family history (p=0.012) were associated with TCM use. Ethnicity showed a significant adverse impact on TCM use [OR=-1.140 (95%CI: 0.170 – 0.603), p&lt;0.001]. There were significant changes in total BMI (p&lt;0.001) among subjects from pre-diagnosis to follow-up. Overall mean energy and protein intake was 22kcal/kg bodyweight and 0.75gram/kg bodyweight, respectively. Dietary supplements were the most often utilized TCM (79.7%), and 37.3% began using TCM before conventional treatment. Only 56.4% of subjects disclosed their TCM use to their doctor, and 61% believed TCM was useful in cancer treatment. There was no difference in nutritional status between T&amp;CM users and non-users. However, many newly diagnosed cancers patients have shown reluctance to pursue standard therapy, citing fear of side effects as the primary cause. Patient education is essential, and practitioners should be aware of the use and safety of TCM.

Energy expenditure and dietary intake in professional female football players in the Dutch Women’s League: Implications for nutritional counselling

ABSTRACT In contrast to male football players, research on the nutritional requirements of female football players is limited. This study aimed to assess total daily energy expenditure (TDEE) in professional female football players, along with body composition, physical activity and dietary intake. This observational study included 15 professional football players playing in the highest Dutch Women’s League. TDEE was assessed by doubly labelled water over 14 days, along with resting metabolic rate (RMR; ventilated hood), fat-free mass (FFM; dual-energy x-ray absorptiometry), and dietary intake (24-h recalls). Physical activity energy expenditure (PAEE) was derived from subtracting RMR and estimated diet-induced thermogenesis (10%) from TDEE. TDEE was 2882 ± 278 kcal/day (58 ± 5 kcal/kg FFM) and significantly (p < 0.05) correlated with FFM (r = 0.62). PAEE was 1207 ± 213 kcal/d. Weighted energy intake was 2344 kcal [2023–2589]. Carbohydrate intakes were 3.2 ± 0.7, 4.4 ± 1.1 and 5.3 ± 1.9 g/kg body mass for rest, training and match days, respectively, while weighted mean protein intake was 1.9 ± 0.4 g/kg body mass. In conclusion, the energy requirements of professional female football players are moderate to high and can be explained by the substantial PAEE. To fuel these requirements, sports nutritionists should consider shifting the players’ focus towards prioritizing adequate carbohydrate intakes, rather than emphasizing high protein consumption.

2027 Protein consumption and determinants in community dwelling older adults: National Diet and Nutrition Survey (NDNS) years 9-11

Abstract Introduction Reference nutrient intake for protein amongst the general population is 0.75 grammes of protein per kilogram of body weight per day (g/kg BW/d). Expert groups recommend healthy adults over 65years have 1.0-1.2g/kg BW/d to support good health and maintain functionality (Deutz, Bauer and Barrazoni, Clinical Nutrition, 33(6):929-36). A recent paper suggested age specific recommendations of 1.2g/kg BW/d (Dorrington, Fallaize and Hobbs, Journal of Nutrition, 150(9):2245-2256). This study aimed to quantify percentage of community dwelling older adults meeting recommendations for protein intake and explore factors associated with low consumption. Methods The study population comprised &amp;gt;65s completing the NDNS survey years 9-11 (2016-2019). Dietary intake was recorded in food diaries. Protein consumption was calculated as grammes per kilogram adjusted body weight per day (g/kg aBW/d). Adjustment made for body mass index (BMI) below 22kg/m2 and above 27kg/m2. Percentage of participants meeting protein recommendations for 0.75, 1.0 and 1.2g/kg BW/d was calculated. Chi-squared test for independence was utilised to determine association between social, health and lifestyle factors and low protein intake. Results Data from 385 participants were included; 43% male, 98% white. Mean protein intake was 0.98g/kg aBW/d (SD ±0.25). Prevalence of protein intake below 0.75g/kg aBW/d was 16.4% (n=63), below 1.0g/kg aBW/d was 52.2% (n=201) and below 1.2g/kg aBW/d 82.1% (n=316). Current and ex-regular smoking was associated with protein intake &amp;lt;1g/kg aBW/d (p=0.01). No other analysis reached statistical significance although prevalence of low protein intake was higher in those without their own teeth (p=0.08), use of dentures (p=0.14) and BMI of 27-30kg/m2 (p=0.09). Conclusion A large percentage of older adults are below expert recommendations for protein intake. There is a need for clarity over recommendations so that a clear public message can be given to optimise health and function in ageing. Factors influencing poor protein intake require further examination.

A study on behavior, diet patterns and physical activity among selected GDM and non-GDM women in south India

Abstract Aim: Our aim is to study the behavior, diet, and physical activity patterns among gestational diabetes mellitus (GDM) and non-GDM women. Materials and Methods: A survey was conducted among GDM and non-GDM women from multispeciality hospitals and maternal clinics using a purposive sampling criterion. A validated interview schedule was used to obtain details of readiness for pregnancy, perception of managing pregnancy, concerns in pregnancy, degree of depression, food preferences, shopping of food, eating out, cooking, current nutrient intake, food consumption pattern, type, duration and frequency of physical activity, and rest periods of GDM and non-GDM women. Results: Majority of GDM and non-GDM women showed readiness for motherhood. GDM women exhibited greater confidence and importance toward making lifestyle changes during pregnancy. The pregnancy-related concerns were more common among GDM women. The mean energy and protein intake was lower than the recommended dietary allowance (RDA) among GDM women compared to their counterparts. On the contrary, carbohydrate consumption exceeded RDA among both groups. The total fat intake, including visible and invisible fat among GDM women, met the RDA; however, it exceeded the RDA among non-GDM women. The RDA for calcium, iron, and fiber showed significant difference compared to RDA among both groups. Physical activity patterns did not show any significant difference among GDM and non-GDM women and were unsatisfactory in both groups. Conclusion: The study recommends the need for psychological support, proper medical nutrition therapy, and adequate physical activity for GDM and non-GDM women.

A Short Dietary Assessment Instrument to Evaluate Protein Quality and the Diversity of Protein Sources in Malaysian Diets.

The diversity of protein food sources, animal and plant, may be a proxy measure of protein quality and adequate protein nutrition. A population-based sample of 1604 Malaysians aged ≥18 y completed one 24-h dietary recall and a new 29-item protein diversity indicator (PDI). Socio-demographic data were obtained by self-report. Mean total protein intakes were 75.2 g/d from 24-h recalls and 74.9 g/d from PDI. Protein diversity indicator-estimated protein intakes were 36.2% from meat and poultry, 8.8% from fish, 16.0% from eggs and dairy, and 39.0% from plants. Intakes of animal proteins varied with socioeconomic status and ethnicity and were associated with higher protein quality, defined as the adequacy of essential amino acids (EAAs) relative to protein requirements. Protein intakes and protein quality in Malaysia were generally adequate. Protein diversity indicator metrics can complement current methods of dietary assessment and may be useful for monitoring protein diversity and quality in other countries currently undergoing nutrition transition.

Exploring the short-term impact of swapping consumption from standard protein snacks to higher protein snacks on energy intake in social drinkers: Is protein worth a nudge?

Drinking alcoholic beverages stimulates food intake and contributes to the passive overconsumption of dietary energy. As protein is the most satiating of all the macronutrients, increased levels in snacks taken with alcohol have the potential to minimize excess energy consumption. We hypothesized that swapping consumption from retail-available standard protein (SP) snacks to higher protein (HP) snack foods would increase satiety and reduce acute food energy intake in social drinkers. A randomized single-blind crossover trial with 19 healthy participants aged 19-31 years was conducted. Participants attended two separate testing sessions, where they ingested white wine (30 g alcohol) and were offered adlibitum access to either HP snacks with a protein-fortified dip or SP snacks with a dip. There were no significant differences in mean food mass, food energy intake, or subjective appetite ratings between the high and SP snacks (all p > .05). Mean protein intake was significantly increased with HP snacks compared with standard snacks (p < .001). Plasma glucose median incremental area under the curve and mean peak were significantly higher with the SP snacks (all p < .05) but remained within the reference range. This study demonstrated that consumption of a higher amount of protein after a moderate alcohol dose does not result in a change in food mass and energy intake or promote satiety in healthy young adults. The potential for a simple swap to different snack types is unlikely to bring substantial benefits to social drinkers and reduce passive energy consumption.

Differences in Intakes of Select Nutrients by Urbanization Level in the United States Population 2 Years and Older, NHANES 2013–2018

BackgroundDifferences in nutrient intakes by urbanization level in the Unites States is not well understood. ObjectiveDescribe, by urbanization level: 1) intake of protein, fiber, percent of energy from added sugars (AS) and saturated fat (SF), calcium, iron, potassium, sodium, and vitamin D; 2) the percent of the population meeting nutrient recommendations. MethodsTwenty-four-hour dietary recalls from 23,107 participants aged 2 y and over from the 2013–2018 National Health and Nutrition Examination Surveys were analyzed. Usual intakes were estimated, and linear regression models adjusted for age, sex, race and Hispanic origin, and whether family income met the 130% threshold examined intake differences by urbanization levels—large urban areas (LUA), small to medium metro areas (SMMA), and rural areas (RA). ResultsA small percentage of the population met the nutrient recommendations, except for protein (92.8%) and iron (70.5%). A higher percentage of the population met recommendations than SMMA and RA for fiber (11.8% compared with 8.1% and 5.3%, P < 0.001), AS (40.2% compared with 33.4% and 31.3%, P < 0.001), SF (26.8% compared with 18.2% and 20.1%, P < 0.001), and potassium (31.5% compared with 25.5% and 22.0%, P < 0.001). Mean protein intake were also higher in LUA than RA (80.0 g compared with 77.7 g, P = 0.003) and fiber intake higher in LUA than SMMA (16.5 g compared with 15.9 g, P = 0.01) and RA (16.5 g compared with 15.2 g, P = 0.001). In addition, contributions to energy intake were lower in LUA than SMMA for AS (11.3% compared with 12.0%, P < 0.001) and SF (11.5% compared with 11.7%, P < 0.001), and for LUA than RA for AS (11.3% compared with 12.9%, P < 0.001) and SF (11.5% compared with 11.8%, P < 0.001). ConclusionsRA had some markers of poorer diet quality—lower protein and fiber intake and higher AS intake—compared with LUA, and these differences persisted in adjusted regression models. These results may inform public health efforts to address health disparities by urbanization levels in the Unites States.

Relationship of protein, calcium and vitamin D consumption with body composition and fractures in oldest-old independent people

Some studies state that the protein intake has a protective effect against bone mass loss, while others show that the combination of low calcium intake and high protein consumption increases the risk of fractures. Perhaps this phenomenon is also altered by the consumption of vitamin D after the age 80 years. This study aimed to identify if there is an association of protein, calcium and vitamin D intake with body composition and fractures in community dwelling 80 years or older independent people. This is a cross-sectional observational analytic study. We invited community dwelling 80 years or older independent people, with chronic diseases under control, according to the scientific guidelines. The food intake was obtained through a one-day food record (FR) and Avanutri software (4.1 version) was used to calculate the intake of total calories, calcium, protein, and other food nutrients. The body composition and bone densitometry were evaluated by whole-body Dual Energy X-ray Absorptiometry (DXA). The morphometric vertebral fractures were assessed through conventional X-ray of the vertebral, level T4 to L4, on side face position - semi quantitative technique. One hundred and fifty-nine 80 years or older independent people, mean age 87.0±3.9 years old were studied. The mean calcium intake was 834.6±374.7mg/day and vitamin D was 6.1±24.3μg/day, in both cases they were complemented by supplements to reach the recommendations. The mean protein intake was 72.9±26.8g/day, we found that 48.4% had low muscle mass; there was a frequency of 45.3% of osteoporosis; and vertebral fractures in 24.7% of them. The estimates of the logistic regression model with the outcome variable obesity and low muscle mass with reference to "low muscle mass" showed that the 80 years or older independent people who have a fracture are more likely to be obese with low muscle mass compared to those with only low muscle mass. In the studied population of 80 years or older independent people, we observed that among all the nutrients studied, only dietary protein per g/kg/day was associated with body composition and bone mineral density, but not with fracture, although the elderly who have fracture are more likely to be obese with low muscle mass compared to those not obese with low muscle mass. More studies about nutrients intakes and its relationship with muscle and bone health in this population is necessary.

Associations between High Protein Intake, Linear Growth, and Stunting in Children and Adolescents: A Cross-Sectional Study.

Childhood and adolescence are critical periods for linear growth and preventing stunting. Current evidence indicates that dietary protein intake in children and adolescents is often two to three times higher than the recommendations in many regions worldwide. However, few studies have focused on the association between high protein intake and linear growth and stunting in this population. We aim to investigate this association in children and adolescents aged 6 to 18 years in a population with relatively high protein consumption. We conducted a large cross-sectional study involving 3299 participants from Shenzhen, a modern metropolis of China. Protein intake, including total protein, animal protein, and plant protein, was evaluated by a food-frequency questionnaire and expressed as grams per kilogram of body weight per day (g·kg-1·d-1) and as a percentage of total energy intake (%E). The primary outcomes were body height and height-for-age Z score (HAZ). Generalized linear models and logistic regression analyses were employed to examine the associations between protein intake and outcomes. We also conducted stratified analyses across different genders and pubertal stages in the aforementioned associations. The mean protein intake was 1.81 g·kg-1·d-1 (17% E). After adjusting for serum calcium, zinc, vitamin D3, vitamin A levels, birth outcomes, lifestyle, and parental characteristics, each standard deviation increase of 1 in protein intake (0.64 kg-1·d-1) is found to be associated with a -5.78 cm change in body height (95% CI: -6.12, -5.45) and a -0.79 change in HAZ (95% CI: -0.84, -0.74). Consistent results were observed when protein intake was expressed as %E or specifically as animal or plant protein. Moreover, the relationship between protein intake and linear growth remained consistent across genders in different pubertal stages, similar to that of the overall participants. Our findings highlight the potential hazards of high protein intake on linear growth in children and adolescents. Caution should be exercised when promoting increased protein consumption in children and adolescents who already have a high intake of protein.

Development of a food frequency questionnaire to monitor protein intake in Flanders, Belgium

Abstract Background To improve planetary and dietary health, the Flemish government adopted the ‘Green Deal Protein Shift on our plate’ policy which aims to reverse the ratio between animal-based and plant-based protein-rich products in our diet to 40/60 by 2030. The Green Deal provides a platform for actions that unites players from across the food system. To guide the development of actions and assess their effectiveness it is crucial to closely monitor the protein consumption of the population. Methods We developed a semi-quantitative Food Frequency Questionnaire (FFQ) to be self-completed annually (2023-2030) by a representative sample of 1000 adults (18-65 years). The food list of the FFQ was developed using a stepwise approach based on the Belgian food consumption survey 2014, selecting the 90% most contributing foods to protein intake. New foods retrieved from a market research and expected innovations were added. Similar foods were combined into survey items, and portion size questions added. Protein intake was estimated using the weighted mean protein intake of the 90% most consumed foods represented in each item. A content validation study was performed to assess question comprehension, food identification and quantification. Results will allow to estimate average protein intake and evolution of protein sources over time. Results The FFQ includes 60 food items. The average completion time was 16 minutes. The content validation let to re-ordering of food items and reformulation of portion descriptions. Conclusions The newly developed FFQ will strengthen the Flemish public health surveillance system: monitoring protein intake and the ratio of animal-based versus plant-based and alternative protein will allow to guide actions and track progress towards policy objectives of the ‘Green Deal Protein Shift on our plate'. Key messages • This study highlights the role of public health surveillance systems in monitoring new policy actions and progress towards policy objectives. • This study highlights the development of rapid screening tools using a database approach and market research data.

Validation of a food frequency questionnaire in the assessment of dietary glycemic index, glycemic load, and protein intake in pregnant women with obesity

ObjectivesStudies suggest that diets with a low glycemic index and high protein are favorable in aiding weight loss and improving weight maintenance; however, methods to measure dietary intake are comprehensive both for the participant and the study staff. We aimed to validate the accuracy of the dietary glycemic index and protein intake assessed through a food frequency questionnaire against a 4-d weighed food record in Danish pregnant women with obesity. MethodsA total of 31 pregnant women completed a 29-item food frequency questionnaire and a 4-d weighed food record with overlapping time periods. The women had a mean (± SD) age of 30.6 ± 3.9 y and a prepregnancy body mass index of 33.9 ± 3.5 kg/m2. We evaluated the validity of the food frequency questionnaire by Bland-Altman plots and the Spearman correlation coefficient. ResultsThe results of the validation study found good acceptance of the 29-item food frequency questionnaire. The mean intake of glycemic index, glycemic load, and protein intake of the 29-item food frequency questionnaire and the weighed food record correlated well, although intake data of the 29-item food frequency questionnaire tended to be lower. Spearman correlation coefficients had moderate to high correlations for glycemic index (ρ = 0.73; P < 0.001) and protein intake (ρ = 0.70; P < 0.001). A moderate correlation was found for glycemic load (ρ = 0.55; P = 0.002). There was no correlation for carbohydrates (ρ = 0.21; P = 0.253). ConclusionThe results suggest no risk of bias between the two methods of assessment; hence, a 29-item food frequency questionnaire can be used to assess the mean glycemic index, glycemic load, and protein intake in pregnant women with obesity.

Protein supplement consumption prevalence, habits and complications in adolescents

IntroductionThe consumption of nutritional and protein supplements by adolescents may have important consequences for their health. MethodsProspective observational study based on a survey of adolescents enrolled in 6 schools selected at random in the city of Seville. Our primary objective was to determine the actual consumption of dietary supplements in the adolescent population and quantifying their protein content. ResultsWe obtained a total of 263 valid responses that showed a prevalence of consumption of nutritional supplements of any kind of 19.01%, of which 56.0% (10.64% of the total) corresponded to adolescents that consumed protein supplements for a mean protein intake of 0.26 g/kg/day (SD, 0.18). The profile of consumers of any type of supplements differed from that of nonconsumers in age, use of long-term medication and weight loss or high-protein diets. The comparison of adolescents who consumed protein supplements versus nonprotein supplements only evinced a significant difference in the control of supplement consumption. Although most of these adolescents were not subject to external control, 25.92% of those who consumed protein supplements were monitored by a professional, compared to 7.38% of consumers of nonprotein supplements. In the group that consumed protein supplements, 85.18% of adolescents achieved the desired effect and 18.51% reported some form of negative effect. ConclusionsThe prevalence of protein supplement consumption among adolescents in our area is 10.64%, with consumption of amounts corresponding to 25% of the recommended daily allowance of protein. The profile of protein supplement consumers is very similar to that of nonprotein supplement consumers.

A Study of Prevalence and Underlying Causes of Undernutrition among Santal Pre-School Children (1-5 Years) of West Bengal

(Boys - 86.63% and Girls – 56.10%), stunting (Boys -76.24% and Girls – 57.56%) and wasting (Boys - 59.41% and Girls – 30.73%) were significantly higher in boys than girls in santal pre-school children. Dietary assessment showed that mean energy and protein intake were lower amount in santal boys and girls compare with RDA of India. Health assessment found that prevalence of common diseases was fever, common cold, diarrhoea, dysentery, scabies and jaundice in santal pre-school children. Santal boys were more vulnerable than santal girls with these diseases like fever, common cold and jaundice. Study also found that most of the parents in santal children preferred treatment during illness or disease by unqualified quack doctor than health centre or hospital and private MBBS clinic. It was found that overall economic condition of santal children family’s was very poor. Analysis of literacy in parents showed that percentage of illiteracy of both father and mother was very poor in santal pre-school children and fathers of santal communities were involved with verities type of occupation. Most of the santal families used unsafe drinking water and their sanitary facility was also very poor. Food pattern and socio-cultural practices were remarkably very poor. The study suggests that santal pre-school children of both Bankura and Paschim Medinipur are suffering from undernutrition severely in the form of stunting, underweight and wasting. This may be not only dietary inadequacy of protein and energy of their diet but also their poor health status which again may be a reflection of poor socio economic, socio cultural and unhygienic personal habits of the community.

Prevalencia, hábitos de consumo y complicaciones de los suplementos nutricionales proteicos en adolescentes

IntroductionThe consumption of nutritional and protein supplements by adolescents may have important consequences for their health. Material and methodsProspective observational study based on a survey of adolescents enrolled in six schools selected at random in the city of Seville. Our primary objective was to determine the actual consumption of dietary supplements in the adolescent population and quantifying their protein content. ResultsWe obtained a total of 263 valid responses that showed a prevalence of consumption of nutritional supplements of any kind of 19.01%, of which 56.0% (10.64% of the total) corresponded to adolescents that consumed protein supplements for a mean protein intake of 0.26 g/kg/day (SD, 0.18).The profile of consumers of any type of supplements differed from that of nonconsumers in age, use of long-term medication and weight loss or high-protein diets. The comparison of adolescents who consumed protein supplements versus nonprotein supplements only evinced a significant difference in the control of supplement consumption. Although most of these adolescents were not subject to external control, 25.92% of those who consumed protein supplements were monitored by a professional, compared to 7.38% of consumers of nonprotein supplements. In the group that consumed protein supplements, 85.18% of adolescents achieved the desired effect and 18.51% reported some form of negative effect. ConclusionsThe prevalence of protein supplement consumption among adolescents in our area is 10.64%, with consumption of amounts corresponding to 25% of the recommended daily allowance of protein. The profile of protein supplement consumers is very similar to that of nonprotein supplement consumers.

Actual dietary intake versus dietary recommendation among patients with chronic kidney disease!-an observational study

Background: As diet is an important component of chronic kidney disease management. It is important to understand the actual dietary intake of these patients and see if they are able to meet their respective recommended dietary allowance (RDA), failing which they are predisposed to malnutrition. Hence the study was carried out to assess the actual dietary intake of the subjects with chronic kidney disease to understand the gap between recommendation and actual intake. Aim of this study was to assess the dietary intake of patients with chronic kidney disease. Methods: Patients with chronic kidney disease in stages 3 and 4 were recruited based on the inclusion criteria and the information on demographics, medical history, subjective data and seven-day dietary recall were obtained. The quantitative and qualitative estimation of the seven-day dietary intake was computed using “Dietcal” software. Results: Anorexia was observed among 54% of the study participants. The mean calorie, protein and carbohydrate intake was 959.69±166.49 Kcals, 27.94±5.36 g and 160.5±26.7 g respectively while mean intake of sodium, potassium and phosphorous were 88.65±42.88 mg, 944.5±188.69 mg and 560.77±127.64 mg respectively. Conclusions: The actual dietary intake was lesser than the recommended intake as influenced by anorexia, dysguesia, early satiety and dietary restrictions. Poor nutrient intake per se is the primary influential factor in the onset of malnutrition. Hence, it is important to adopt customized approach rather than generalized nutrient restrictions imposed upon these patients.
