RESUMEN
Glutaric aciduria type 1 is a rare inherited neurometabolic disorder of lysine metabolism caused by pathogenic gene variations in GCDH (cytogenic location: 19p13.13), resulting in deficiency of mitochondrial glutaryl-CoA dehydrogenase (GCDH) and, consequently, accumulation of glutaric acid, 3-hydroxyglutaric acid, glutaconic acid and glutarylcarnitine detectable by gas chromatography/mass spectrometry (organic acids) and tandem mass spectrometry (acylcarnitines). Depending on residual GCDH activity, biochemical high and low excreting phenotypes have been defined. Most untreated individuals present with acute onset of striatal damage before age 3 (to 6) years, precipitated by infectious diseases, fever or surgery, resulting in irreversible, mostly dystonic movement disorder with limited life expectancy. In some patients, striatal damage develops insidiously. In recent years, the clinical phenotype has been extended by the finding of extrastriatal abnormalities and cognitive dysfunction, preferably in the high excreter group, as well as chronic kidney failure. Newborn screening is the prerequisite for pre-symptomatic start of metabolic treatment with low lysine diet, carnitine supplementation and intensified emergency treatment during catabolic episodes, which, in combination, have substantially improved neurologic outcome. In contrast, start of treatment after onset of symptoms cannot reverse existing motor dysfunction caused by striatal damage. Dietary treatment can be relaxed after the vulnerable period for striatal damage, that is, age 6 years. However, impact of dietary relaxation on long-term outcomes is still unclear. This third revision of evidence-based recommendations aims to re-evaluate previous recommendations (Boy et al., J Inherit Metab Dis, 2017;40(1):75-101; Kolker et al., J Inherit Metab Dis 2011;34(3):677-694; Kolker et al., J Inherit Metab Dis, 2007;30(1):5-22) and to implement new research findings on the evolving phenotypic diversity as well as the impact of non-interventional variables and treatment quality on clinical outcomes.

Glutaric aciduria type I (GA-I; synonym, glutaric acidemia type I) is a rare inherited metabolic disease caused by deficiency of glutaryl-CoA dehydrogenase located in the catabolic pathways of L-lysine, L-hydroxylysine, and L-tryptophan. The enzymatic defect results in elevated concentrations of glutaric acid, 3-hydroxyglutaric acid, glutaconic acid, and glutaryl carnitine in body tissues, which can be reliably detected by gas chromatography/mass spectrometry (organic acids) and tandem mass spectrometry (acylcarnitines). Most untreated individuals with GA-I experience acute encephalopathic crises during the first 6 years of life that are triggered by infectious diseases, febrile reaction to vaccinations, and surgery. These crises result in striatal injury and consequent dystonic movement disorder; thus, significant mortality and morbidity results. In some patients, neurologic disease may also develop without clinically apparent crises at any age. Neonatal screening for GA-I us being used in a growing number of countries worldwide and is cost effective. Metabolic treatment, consisting of low lysine diet, carnitine supplementation, and intensified emergency treatment during catabolism, is effective treatment and improves neurologic outcome in those individuals diagnosed early; treatment after symptom onset, however, is less effective. Dietary treatment is relaxed after age 6 years and should be supervised by specialized metabolic centers. The major aim of this second revision of proposed recommendations is to re-evaluate the previous recommendations (Kölker et al. J Inherit Metab Dis 30:5-22, 2007b; J Inherit Metab Dis 34:677-694, 2011) and add new research findings, relevant clinical aspects, and the perspective of affected individuals.

This study assessed caregivers' knowledge and practices and factors that influence the adoption of improved infant and young child feeding (IYCF) practices after nutrition education in Kasungu and Mzimba districts among 198 caregivers. Mixed-methods convergent-parallel design, including knowledge tests, focus group discussions, and in-depth interviews in the intervention areas, was used to collect quantitative and qualitative data. Data were analyzed using count regression and content analysis, which showed that knowledge increased among caregivers after nutrition education. The knowledge about diet diversification for young children as well as about hygienic practices when preparing food and during feeding improved in addition. Enhanced health among children motivated caregivers to apply improved IYCF practices. The study was based on the caregivers' reports. Long-term effects of exposure to nutrition education are unknown. However, the nutrition education that focused on the child's health benefits motivated mothers to adopt improved IYCF practices.

Poor infant and young child feeding (IYCF) practices are major determinants of chronic malnutrition. The main objective of this study was to assess the impact of a nutrition education (NE) programme aimed at promoting improved IYCF behaviours in combination with an agriculture intervention on children's dietary diversity and nutritional status. From 2012 to 2014, a cluster randomised trial was rolled out in Cambodia in the context of an agriculture and nutrition project of the FAO of the UN. The cross-sectional baseline study was carried out in sixteen pre-selected communes in 2012. Restricted randomisation allotted the communes to either intervention (NE and agriculture intervention) or comparison arms (agriculture intervention only). The impact survey was conducted as a census in all FAO project villages in 2014. Caregivers of children aged 0-23 months were interviewed using standardised questions on socio-economic status and dietary diversity (24-h recall). Anthropometric measurements were taken. A difference-in-differences model was applied. The sample comprised 743 households with children ≥6 months of age at baseline and 921 at impact. After 1 year of NE, 69 % of the intervention households reported to have participated in the NE. Estimated mean child dietary diversity was significantly different at impact between comparison and intervention (3·6 and 3·9, respectively). In particular, the consumption of pro-vitamin A-rich foods and other fruits and vegetables increased. No treatment effects on height-for-age Z-scores could be shown. NE led to improvements in children's diets. For effects on growth, it is assumed that longer NE activities are required to achieve sustainable behaviour change of age-appropriate infant feeding.

OBJECTIVE: Lack of diversity is a major factor contributing to inadequate nutrient intakes among children during the complementary feeding period in many rural areas in developing countries. This has been attributed to inadequate feeding practices and nutrition knowledge among their caregivers. The aim of the present study was to assess the effect of an educational intervention on children's dietary diversity and nutrition knowledge of caregivers. DESIGN: Cluster randomization was applied and twenty matched village pairs were randomly assigned to the intervention or control group. The nutrition education intervention consisted of four sessions comprising of group trainings and cooking demonstrations that were conducted over a period of 5 months. SETTING: Households in rural communities in Bondo and Teso South sub-counties, western Kenya. SUBJECTS: Caregivers with children aged 6-17 months receiving nutrition education. RESULTS: The children's dietary diversity scores (CDDS) and nutrition knowledge scores of the caregivers improved significantly in the intervention group at endline. The treatment effect on CDDS was positive and significant (P=0.001). The CDDS rate of the children in the intervention group was 27% larger than it would have been without the treatment effect. The intervention also had a significant effect on the caregivers' nutrition knowledge scores (incidence rate ratio=2.05; P<0.001). However, the nutrition knowledge of the caregivers did not have a significant effect on CDDS (P=0.731). CONCLUSIONS: The nutrition education intervention led to improvements in children's dietary diversity and nutrition knowledge of the caregivers.

Breast cancer is the leading cause of death among women worldwide. Studies in industrialised countries identified age at menarche, age at first full-term pregnancy, and lactation as determining factors in the aetiology of breast cancer. 115 female breast cancer patients (cases) and 230 age- and district-matched women clinically free from breast cancer (controls) were interviewed about their reproductive history and socioeconomic condition. Semi-structured interviews including anthropometric measurements were conducted by trained enumerators. The median age was 50 years (min/max 26 to 85 years). Estimated median BMI at age 20 was 21 kg/m(2) in both cases and controls. Median lifelong lactation of the mothers was 96 months (cases) and 108 months (controls). A high BMI at 20 years was associated with an increased breast cancer risk (OR 1.31 95% CI 1.11-1.55, P < 0.01). The odds ratio for lifelong lactation was slightly below one (OR 0.99 95% CI 0.98-1.00, P < 0.01). There was no significant association in risk for BMI at interview (median 25 kg/m(2) of cases and 26 kg/m(2) of controls), age at menarche (median 16 years), and age at first full-term pregnancy (median 20 years). The association of increased risk with higher BMI at age 20 years remained significant after stratification for menopause (premenopausal: OR 1.41 95% CI 1.10-1.81, P = 0.01; postmenopausal: OR 1.38 95% CI 1.06-1.80, P = 0.02). Late age at menarche and prolonged lifelong lactation were associated with a risk reduction among premenopausal women (ORmenarche 0.74 95% CI 0.56-1.00, P = 0.05; ORlactation 0.98 95% CI 0.97-0.99, P < 0.01). In conclusion, long-standing lactation and reproductive behaviour are associated with a lower breast cancer risk in the region. As current changes in lifestyle affect age at menarche, reproductive behaviour, and nutritional status, an increased incidence of breast cancer is to be expected. Preventive efforts should include advice on reproductive and breastfeeding behaviour.

BACKGROUND: Breast cancer is the second most common cancer among women in the Kilimanjaro Region of Tanzania. It was tested within a case-control study in this region whether a specific dietary pattern impacts on the breast cancer risk. METHODS: A validated semi-quantitative Food Frequency Questionnaire was used to assess the dietary intake of 115 female breast cancer patients and 230 healthy age-matched women living in the same districts. A logistic regression was performed to estimate breast cancer risk. Dietary patterns were obtained using principal component analysis with Varimax rotation. RESULTS: The adjusted logistic regression estimated an increased risk for a "Fatty Diet", characterized by a higher consumption of milk, vegetable oils and fats, butter, lard and red meat (OR = 1.42, 95 % CI 1.08-1.87; P = 0.01), and for a "Fruity Diet", characterized by a higher consumption of fish, mango, papaya, avocado and watery fruits (OR = 1.61, 95 % CI 1.14-2.28; P = 0.01). Both diets showed an inverse association with the ratio between polyunsaturated and saturated fatty acids (P/S ratio). CONCLUSION: A diet characterized by a low P/S ratio seems to be more important for the development of breast cancer than total fat intake.

Even in the 21st century, undernutrition is a challenge to be overcome. In the year 2009, 1.02 billion people were reported as food insecure and 180 million children were undernourished. Food insecurity and undernutrition are more than a lack of food energy: they are not reflected countrywide by prevalence means; they are mostly not permanent but seasonal; they are mostly not caused by insufficient amounts of food being produced; and they first affect parents and later children. Food insecurity and undernutrition often manifest themselves as micronutrient deficiency. While undernutrition is still a challenge for global nutrition, a second challenge has arisen: preventing caloric overnutrition. In various countries, food pyramids or food circles have been plotted supporting nutrition education and illustrating the challenge. Such integrative approaches are desirable for all countries of the world, as in all countries, to a smaller or larger extent, undernutrition and caloric overnutrition are the problems of today and tomorrow. The International Assessment of Agriculture for Science Technology and Development (IAASTD) has paid attention to the inescapable interconnectedness of agriculture's different roles and functions in the world and in all societies. Overcoming undernutrition with local resources means first protecting and promoting the use of local resources against imports of low-priced processed foods from subsidised production in industrialised countries; second, it means developing education and training material for regional food production with a nutrition orientation; and third, the experiences of organic farming can contribute much to support farmers in developing countries in planting their indigenous varieties and applying integrated pest management strategies.

Adolescent health and well-being are of great concern worldwide, and adolescents encounter particular challenges, vulnerabilities and constraints. The dual challenges of adolescent parenthood and obesity are of public health relevance because of the life-altering health and socioeconomic effects on both the parents and the offspring. Prevention and treatment strategies at the individual and population levels have not been successful in the long term, suggesting that adolescent pregnancy and obesity cannot be managed by more of the same. Here, we view adolescent obese pregnancy through the lens of the social contract with youth. The disruption of this contract is faced by today's adolescents, with work, social and economic dilemmas which perpetuate socioeconomic and health inequities across generations. The lack of employment, education and social opportunities, together with obesogenic settings, increase vulnerability and exposure to lifelong health risks, affecting their offspring's life chances too. To break such vicious circles of disadvantage and achieve sustainable solutions in real-world settings, strong efforts on the part of policymakers, healthcare providers and the community must be oriented towards guaranteeing equity and healthy nutrition and environments for today's adolescents. The involvement of adolescents themselves in developing such programs is paramount, not only so that they feel a sense of agency but also to better meet their real life needs.

Small-holder farm households in developing countries mainly depend on rain-fed agriculture activities, thus seasonality affects eating habits and contributes to micronutrient deficiencies. This study assessed women's dietary diversity score (WDDS) across three agricultural seasons in the Kapchorwa District, Uganda. In each season, 445 women with under five-year-old children from small-holder farm households were interviewed on socio-demographic characteristics as well as dietary practices between May 2016 and January 2017. Linear regression models estimated differences in WDDS across seasons. The mean WDDS at the lean, harvest and post-harvest seasons was 4.33 ± 1.21, 4.63 ± 1.30 and 4.36 ± 1.21, respectively. Mean WDDS was higher in urban regions across all seasons. Women in urban regions generated more income through off-farm activities, had better access to markets and consumed significantly more 'meat, poultry and fish' (p < 0.001), dairy products (p < 0.05), 'vitamin A-rich fruits and vegetables' (p < 0.001) and 'other vegetables' (p < 0.001) during the lean season, whilst rural women ate more dark green leafy vegetables (p < 0.001) during the same period. Poorer households in the rural setting were more likely to be affected by seasonally limited food availability and accessibility. Hence, strengthening the linkages between market participation, agricultural activities, improved food storage and preservation techniques and dietary intake is recommended.
RESUMEN
BACKGROUND: Many developing countries are experiencing a rapid nutrition transition in urban areas. OBJECTIVE: To investigate whether a nutrition transition was occurring in a rural area by examining the dietary patterns of women in rural Tanzania. METHODS: A total of 252 women aged 16 to 45 years from three districts of northeastern and central Tanzania participated. During three different seasons in 2006-2007, the women were interviewed with the use of a structured, interviewer-administered questionnaire, including a 24-hour dietary recall. From these recalls, the mean intakes of 12 main food groups were calculated and used to establish five dietary patterns by principal component analysis. Data were also obtained on attitudes toward obesity, body mass index (BMI), hemoglobin level, and measures of socioeconomic status and analyzed for associations with dietary patterns. RESULTS: The five dietary patterns were "traditional-coast," characterized by fruits, nuts, starchy plants, and fish; "traditional-inland," characterized by cereals, oils and fats, and vegetables; "purchase," characterized by bread and cakes (usually fried in oil), sugar, and black tea; "pulses," characterized mainly by pulses, with few or no vegetables; and "animal products," characterized by a high consumption of meat, eggs, and/or milk. Significant positive associations were found, among others, between the purchase pattern and BMI (p = 0.192, p = .005) and between the animal products pattern and wealth (p = 0.168, p = .002). CONCLUSIONS: Differences between traditional and modern nutritional food patterns were evident. This study found the"traditional-inland" pattern to be the most healthy, while the "purchase" food pattern was the most prevalent. The purchase pattern, in particular, may provide some evidence for early stages of the nutrition transition in rural Tanzania.

Seasonal variations in food availability and access contributes to inadequate nutrient intakes, particularly in low income countries. This study assessed the effect of seasonality on dietary diversity (DD) and nutrient intakes of women and children aged 6-23 months in a rural setting in Western Kenya. A longitudinal study was conducted among 426 mother-child pairs during the harvest and post-harvest seasons in 2012. Dietary intakes were assessed using 24-h dietary recalls and dietary diversity scores (DDS) and nutrient intakes calculated for both seasons. Effect of seasonality on women dietary diversity scores (WDDS) and children's dietary diversity scores (CDDS) were assessed using generalised linear mixed models (GLMM). The proportion of women consuming diets with high DDS (>4 out of 9 food groups) increased from 36.4 to 52.4% between the two seasons, with mean WDDS being significantly higher in November compared to July/August (4.62 ± 1.43 vs. 4.16 ± 1.14, P < 0.001). A significantly higher proportion of children consumed foods from ≥4 out of 7 food groups in November compared to July/August (62.4 vs. 52.6%, P = 0.004). Mean CDDS (3.91 vs. 3.61, P = 0.004) was low but significantly higher in November compared to July/August. Estimated marginal mean WDDS increased from 4.17 to 4.38, and decreased for CDDS from 3.73 to 3.60 between the seasons. Seasonality had a small but significant effect on WDDS, P = 0.008 but not on CDDS, P = 0.293. Increase in CDDS in November was due to age and not seasonal effect. Higher women education and household food security were associated with higher WDDS and CDDS. Intakes of iron, calcium and vitamin E were higher among women in November and significantly different between the seasons. Agro-ecological zone, ethnic group and home gardening influenced nutrient intakes of the women. Seasonality had an effect on the DD of women but not of children, thus other factors apart from food availability influence the quality of children's diets during the complementary feeding period. With increasing age and transition to family foods, children's DD is expected to be affected by seasonality. Integrated interventions to alleviate seasonal food insecurity and strengthen rural households' resilience against seasonal deterioration in diet quality are recommended.
RESUMEN
Bitter gourd (BG, Momordica charantia) exerts proven blood glucose- and body weight-lowering effects. To develop an effective and safe application, it is necessary to identify the bioactive compounds and biochemical mechanisms responsible for these effects in type 2 diabetes. A total of forty-five 4-week-old male db/db mice were assigned to five groups of nine each. The mice were given sterile tap water as a control, a whole fruit powder, the lipid fraction, the saponin fraction or the hydrophilic residue of BG at a daily oral dosage of 150 mg/kg body weight for 5 weeks, respectively. Weight gain was significantly decreased in all the BG-treated groups (P ≤ 0.05). Glycated Hb levels were the highest in the control mice compared with all the four BG-treated mice (P = 0.02). The lipid fraction had the strongest effect, and it tended (P = 0.075) to reduce glycated Hb levels from 9.3 % (control mice) to 8.0 % (lipid fraction-treated mice). The lipid and saponin fractions reduced lipid peroxidation of adipose tissue significantly (P ≤ 0.01). Additionally, the saponin fraction and the lipid fraction reduced protein tyrosine phosphatase 1B (PTP 1B) activity in skeletal muscle cytosol by 25 % (P = 0.05) and 23 % (P = 0.07), respectively. PTP 1B is the physiological antagonist of the insulin signalling pathway. Inhibition of PTP 1B increases insulin sensitivity. This is the first study to demonstrate that BG is involved in PTP 1B regulation, and thus explains one possible biochemical mechanism underlying the antidiabetic effects of BG in insulin resistance and type 2 diabetes.

BACKGROUND: Protein Energy Malnutrition is an important cause of child morbidity and mortality in middle- and low-income countries. It has been suggested that excessive free radical activity may be responsible for the clinical manifestation of kwashiorkor. Antioxidants may be able to curb excessive free radical activity and prevent the development of kwashiorkor in susceptible children. OBJECTIVES: To evaluate the benefits of supplementation of vitamin E, selenium, cysteine and riboflavin (alone or in combination) in preventing kwashiorkor. SEARCH STRATEGY: We conducted searches of CENTRAL 2009 (The Cochrane Library 2009 Issue 2), MEDLINE 1966 to 2009, EMBASE 1980 to 2009, CINAHL 1982 to 2009, LILACS 1982 to 2009, Meta register of Controlled trials, Open Sigle, African Index Medicus. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs evaluating vitamin E, selenium, cysteine and riboflavin alone or in combination in healthy pre-school children in middle- and low-income countries. DATA COLLECTION AND ANALYSIS: Two authors extracted and independently analysed data. MAIN RESULTS: One cluster-RCT including 2372 children met our inclusion criteria. Children were randomised, based on household, either to a supplement containing all four micronutrients or to placebo. No statistically significant difference in the incidence of kwashiorkor between the intervention and control groups could be demonstrated at 20 weeks (RR 1.70; 95% CI 0.98 to 2.42). Nor could any statistically significant difference in all-cause mortality be demonstrated (RR 0.75; 95% CI 0.17 to 3.36). AUTHORS' CONCLUSIONS: Based on the one available trial, we could draw no firm conclusion for the effectiveness of supplementary antioxidant micronutrients for the prevention of kwashiorkor in pre-school children.

The double burden of malnutrition presents a great challenge to society and research. Whilst undernutrition in all its forms - wasting, stunting, micronutrient deficiency - still affects millions of children and adults worldwide, overweight and obesity have become increasingly prevalent even in countries where people are sometimes facing food insecurity. Adequate breastfeeding and improved dietary diversity are still goals to be fulfilled. The challenge for scientists as well as administrators and politicians is to address these problems within a framework that is market-oriented almost everywhere. This implies that producers and traders of food attempt to get people to consume as much as possible independent from dietary requirements. Studies have demonstrated gaps in achieving optimal breastfeeding in regions where this type of infant feeding is lifesaving. Most children in sub-Saharan Africa are still not fed a minimum acceptable diet as defined by WHO. Benefits from phytochemicals, like polyphenols and vitamins, are increasingly better understood, as are food effects on the human gut microbiota. Recent research underlines the importance of behavioral change based on information and capabilities. Besides the focus on child growth and public health, the environmental effects of food production and processing need to be considered carefully. The publication of the "Food in the Anthropocene" report has set the stage for developing sustainable food systems everywhere in the world. This requires much more focus on local and regional resources and their optimal utilization.

BACKGROUND: Lunch provision is expected to improve the nutritional status of Cambodian garment workers. The objective of this study is to evaluate the effects of a model lunch provision through a canteen on anthropometry, hemoglobin, and micronutrient status in female garment workers in Cambodia. METHODS: This exploratory randomized controlled trial was implemented at a garment factory in Phnom Penh, Cambodia. Female workers (nulliparous, non-pregnant) were recruited and randomly allocated into an intervention arm (workday's lunch provision) and a control arm. Served lunch sets (~ 700 kcal on average) included diverse local dishes. Anthropometry (body mass index, weight, triceps skinfold thickness, and mid-upper arm muscle circumference), as well as hemoglobin, serum ferritin and soluble transferrin receptor, serum retinol binding protein, and serum folate concentrations were assessed at baseline and after 5 months of lunch provision. A general linear model with adjustments for baseline values was used to estimate intervention effects for each outcome variable. RESULTS: Two hundred twenty-three women were recruited (n = 112 control and n = 111 intervention). 172 (n = 86 in each arm) completed the study. Baseline prevalence of underweight, anemia, depleted iron stores, and marginal iron stores, were 31, 24, 21, and 50%, respectively. Subjects were not affected by frank vitamin A or folate deficiency, whereas 30% showed a marginal folate status. Overall, mean changes in anthropometric variables, hemoglobin, and retinol binding protein were marginal and not significant among intervention subjects. Mean folate concentration increased insignificantly by + 1.1 ng/mL (- 0.02, 2.2) (p = 0.054). On the other hand, mean ferritin decreased by - 6.6 µg/L (- 11.9, - 1.3) (p = 0.015). Subgroup analysis prompts that effects are differently pronounced according to the baseline status of workers. CONCLUSIONS: Findings indicate that model lunch sets provided a beneficial amount of dietary folate, but need to be revisited for iron content and/or iron bioavailability. It is believed that distinct positive effects on anthropometry, hemoglobin, and micronutrient status can solely be expected in malnourished individuals. The authors suggest that similar larger trials, which include sets adapted to the concrete needs of workers affected by underweight, anemia and/or definite micronutrient deficiencies, should be performed. TRIAL REGISTRATION: The trial was registered at the German Clinical Trials Register (9 January 2015, Identifier: DRKS00007666).

The objective of this paper is to compare food consumption by Cambodian garment workers with and without access to a free model lunch provision through a factory-based canteen. Data from an exploratory randomised controlled trial were analysed. In total, 223 female Cambodian garment workers were allocated to an intervention arm (six-month lunch provision) or a control arm. Dietary intake on workdays was assessed by qualitative 24-h recalls at baseline and twice at follow-ups during the period of lunch provision using the Food and Agricultural Organization (FAO) guideline on assessing women's dietary diversity. In total, 158 participants provided complete data on the dietary intake over workdays at all interviews. Lunch provision resulted in a more frequent consumption of dark green leafy vegetables (DGLV), vitamin A-rich fruits, other fruits, and oils and fats during lunch breaks. In contrast, flesh meats, legumes, nuts and seeds, as well as sweets, were eaten at a lower frequency. Except for a higher consumption rate of vitamin A-rich fruits and a lower intake frequency of sweets, lunch provision had a less clear impact on total 24-h intake from different food groups and was not associated with a higher women's dietary diversity score (WDDS). A more gap-oriented design of the lunch sets taking into account underutilised foods and the nutritional status of the workers is recommended.

ETHNOPHARMACOLOGICAL RELEVANCE: Impaired glucose tolerance and diabetes mellitus have become major health issues even in non-industrialized countries. As access to clinical management is often poor, dietary interventions and alternative medicines are required. For bitter gourd, Momordica charantia L., antidiabetic properties have been claimed. AIM OF THE STUDY: The main objective of the intervention study was to assess antidiabetic effects of daily bitter gourd consumption of 2.5g powder over the course of eight weeks among prediabetic individuals. MATERIALS AND METHODS: In a randomized placebo-controlled single blinded clinical trial, 52 individuals with prediabetes were studied after consuming a bitter gourd or a cucumber juice. For reducing the impact of between subject differences in the study population, a crossover design was chosen with eight weeks for each study period and four weeks washout in between. Fasting plasma glucose was chosen as the primary outcome variable. RESULTS: Comparing the different exposures, the CROS analysis (t=-2.23, p=0.031, r=0.326) revealed a significant difference in the change of FPG of 0.31mmol/L (5.6mg/dL) with a trend (R2=0,42387). The number of 44 finally complete data sets achieved a power of 0.82, with a medium-to-large effect size (Cohen's d 0.62). The effect was also proven by a general linear mixed model (estimate 0.31; SE: 0.12; p: 0.01; 95%CI: 0.08; 0.54). Not all participants responded, but the higher the initial blood glucose levels were, the more pronounced the effect was. No serious adverse effects were observed. CONCLUSIONS: Bitter gourd supplementation appeared to have benefits in lowering elevated fasting plasma glucose in prediabetes. The findings should be replicated in other intervention studies to further investigate glucose lowering effects and the opportunity to use bitter gourd for dietary self-management, especially in places where access to professional medical care is not easily assured.

BACKGROUND: The establishment of staff canteens is expected to improve the nutritional situation of Cambodian garment workers. The objective of this study is to assess the nutritive value of low-price model lunch sets provided at a garment factory in Phnom Penh, Cambodia. METHODS: Exemplary lunch sets were served to female workers through a temporary canteen at a garment factory in Phnom Penh. Dish samples were collected repeatedly to examine mean serving sizes of individual ingredients. Food composition tables and NutriSurvey software were used to assess mean amounts and contributions to recommended dietary allowances (RDAs) or adequate intake of energy, macronutrients, dietary fiber, vitamin C (VitC), iron, vitamin A (VitA), folate and vitamin B12 (VitB12). RESULTS: On average, lunch sets provided roughly one third of RDA or adequate intake of energy, carbohydrates, fat and dietary fiber. Contribution to RDA of protein was high (46% RDA). The sets contained a high mean share of VitC (159% RDA), VitA (66% RDA), and folate (44% RDA), but were low in VitB12 (29% RDA) and iron (20% RDA). CONCLUSIONS: Overall, lunches satisfied recommendations of caloric content and macronutrient composition. Sets on average contained a beneficial amount of VitC, VitA and folate. Adjustments are needed for a higher iron content. Alternative iron-rich foods are expected to be better suited, compared to increasing portions of costly meat/fish components. Lunch provision at Cambodian garment factories holds the potential to improve food security of workers, approximately at costs of <1 USD/person/day at large scale. Data on quantitative total dietary intake as well as physical activity among workers are needed to further optimize the concept of staff canteens.
