Associations of plasma total phospholipid fatty acid patterns with feeding practices, growth, and psychomotor development in 6-month-old South African infants.

The objective of this study was to assess plasma fatty acid (FA) patterns of 6-month-old South African infants and to determine their association with feeding practices, growth, and psychomotor development. Plasma total phospholipid FA composition (% of total FAs) of 6-month-old infants (n = 353) from a peri-urban township was analysed, and principal component and factor analysis were performed to identify plasma FA patterns. Feeding practices, anthropometric measurements, and psychomotor development scores were determined. Four major plasma phospholipid FA patterns were identified: A plant-based C18 FA, a high n-6 long-chain polyunsaturated fatty acids (LCPUFA), a C16:1 and long-chain saturated fatty acid (SFA), and a high n-3 and low n-6 LCPUFA pattern. Formula feeding was associated with higher, whereas breastfeeding was associated with lower scores for the plant-based C18 FA and C16:1 and long-chain SFA patterns. On the other hand, breastfeeding, the consumption of cow's milk, and the consumption of semisolid foods were associated with higher scores, whereas formula feeding was associated with lower scores for the high n-6 LCPUFA pattern. Breastfeeding and the consumption of semisolids were also associated with higher high n-3 and low n-6 LCPUFA pattern scores. The C16:1 and long-chain SFA and high n-3 and low n-6 LCPUFA patterns were positively associated with psychomotor development scores. In 6-month-old South African infants, we identified distinct plasma FA patterns that presumably represent the FA quality of their diet and that are associated with psychomotor development. Our results suggest that breast milk is an important source of n-6 LCPUFAs and formula-fed infants may be at risk of inadequate LCPUFA intake.

Consumption of Traditional and Indigenous Foods and Their Contribution to Nutrient Intake among Children and Women in Botswana.

In Botswana, traditional diets are gradually being replaced by westernized diets high in energy-dense and nutrient- poor, while micro nutrient deficiencies among the population remain. We determined the consumption of traditional and indigenous foods (TIF) and their contribution to nutrient intake among children and women in Botswana. TIF accounted for relatively high percentages of energy intake in children (41%) and women (36%) respectively. The mean intake of vitamin A in children and vitamin A and zinc in women was high from TIF compared to non-TIF. Research attention to determining the full potential of TIF in contributing to nutrition and health is warranted.

Inventory on the dietary assessment tools available and needed in africa: a prerequisite for setting up a common methodological research infrastructure for nutritional surveillance, research, and prevention of diet-related non-communicable diseases.

OBJECTIVE: To carry out an inventory on the availability, challenges, and needs of dietary assessment (DA) methods in Africa as a pre-requisite to provide evidence, and set directions (strategies) for implementing common dietary methods and support web-research infrastructure across countries. METHODS: The inventory was performed within the framework of the "Africa's Study on Physical Activity and Dietary Assessment Methods" (AS-PADAM) project. It involves international institutional and African networks. An inventory questionnaire was developed and disseminated through the networks. Eighteen countries responded to the dietary inventory questionnaire. RESULTS: Various DA tools were reported in Africa; 24-Hour Dietary Recall and Food Frequency Questionnaire were the most commonly used tools. Few tools were validated and tested for reliability. Face-to-face interview was the common method of administration. No computerized software or other new (web) technologies were reported. No tools were standardized across countries. CONCLUSIONS: The lack of comparable DA methods across represented countries is a major obstacle to implement comprehensive and joint nutrition-related programmes for surveillance, programme evaluation, research, and prevention. There is a need to develop new or adapt existing DA methods across countries by employing related research infrastructure that has been validated and standardized in other settings, with the view to standardizing methods for wider use.

Household access to traditional and indigenous foods positively associated with food security and dietary diversity in Botswana.

OBJECTIVE: To determine access to traditional and indigenous foods (TIF) and the association with household food security, dietary diversity and women's BMI in low socio-economic households. DESIGN: Sequential explanatory mixed-methods design, including a random household cross-sectional survey on household food insecurity access (HFIA), household dietary diversity (HDD) and women's BMI, followed by focus group discussions. SETTING: Two rural and two urban areas of Botswana. SUBJECTS: Persons responsible for food preparation or an adult in a household (n 400); for BMI, non-pregnant women aged 18-49 years (n 253). RESULTS: Almost two-thirds of households experienced moderate or severe food insecurity (28·8 and 37·3 %, respectively), but more than half of women were overweight or obese (26·9 and 26·9 %, respectively). Median HDD score was 6 (interquartile range 5-7) out of a total of 12. A positive correlation was found between number of TIF accessed and HDD score (r=0·457; P<0·001) and a negative correlation between number of TIF accessed and HFIA score (r=-0·272; P<0·001). There was no correlation between number of TIF accessed and women's BMI (r=-0·066; P=0·297). TIF were perceived as healthy but with declining consumption due to preference for modern foods. CONCLUSIONS: TIF may potentially have an important role in household food security and dietary diversity. There is need to explore potential benefits that may be associated with their optimal use on food security and nutrition outcomes.

Iodine status and associations with feeding practices and psychomotor milestone development in six-month-old South African infants.

Iodine is important for normal growth and psychomotor development. While infants below 6 months of age receive iodine from breast milk or fortified infant formula, the introduction of complementary foods poses a serious risk for deteriorating iodine status. This cross-sectional analysis assessed the iodine status of six-month-old South African infants and explored its associations with feeding practices and psychomotor milestone development. Iodine concentrations were measured in infant (n = 386) and maternal (n = 371) urine (urinary iodine concentration [UIC]), and in breast milk (n = 257 [breast milk iodine concentrations]). Feeding practices and psychomotor milestone development were assessed in all infants. The median (25th-75th percentile) UIC in infants was 345 (213-596) µg/L and was significantly lower in stunted (302 [195-504] µg/L) than non-stunted (366 [225-641] µg/L) infants. Only 6.7% of infants were deficient. Maternal UIC (128 [81-216] µg/L; rs  = 0.218, p < 0.001) and breast milk iodine concentrations (170 [110-270] µg/kg; rs  = 0.447, p < 0.0001) were associated with infant UIC. Most infants (72%) were breastfed and tended to have higher UIC than non-breastfed infants (p = 0.074). Almost all infants (95%) consumed semi-solid or solid foods, with commercial infant cereals (60%) and jarred infant foods (20%) being the most common solid foods first introduced. Infants who reported to consume commercial infant cereals ≥4 days weekly had significantly higher UIC (372 [225-637] µg/L) than those reported to consume commercial infant cereals seldom or never (308 [200-517] µg/L; p = 0.023). No associations between infant UIC and psychomotor developmental scores were observed. Our results suggest that iodine intake in the studied six-month-old infants was adequate. Iodine in breast milk and commercial infant cereals potentially contributed to this adequate intake.

Acceptability of Novel Small-Quantity Lipid-Based Nutrient Supplements for Complementary Feeding in a Peri-Urban South African Community.

BACKGROUND: Small-quantity lipid-based nutritional supplements (SQ-LNS) may potentially be used for home fortification in poor settings, where low nutrient-dense complementary foods are commonly used for infant feeding. However, they need to be acceptable to succeed. OBJECTIVE: This study assessed the acceptability of 2 novel, SQ-LNS (A and B) for supplementing complementary foods among infants aged 6 to 12 months in a peri-urban South African community. METHODS: Both supplements were soy-based pastes and contained micronutrients and essential fatty acids. In addition, supplement B contained docosahexaenoic acid, arachidonic acid, phytase and l-lysine. Mother-infant pairs were enrolled in a 2-part trial. Part 1 (n = 16) was a test-feeding trial with a crossover randomized design, and a 5-point hedonic scale was used for sensory evaluation (disagree = 1, agree = 5). Part 2 (n = 38) was a 2-week, home-use trial followed by focus group discussions. RESULTS: In part 1, more than 70% of mothers reported a score ≥4 on sensory attributes for both SQ-LNSs indicating that both supplements were well perceived. In part 2, the mean reported consumption over the 2-week period was 65.3% ± 34.2% and 62.0% ± 31.3% of the 20 g daily portion for supplements A and B, respectively. Focus group discussions confirmed a positive attitude toward the supplements in the study population. CONCLUSION: This study showed acceptance of both SQ-LNSs in terms of sensory characteristics as well as in terms of practicality for home use.

Effects of a multi-micronutrient-fortified beverage, with and without sugar, on growth and cognition in South African schoolchildren: a randomised, double-blind, controlled intervention.

Little is known about the effects of combined micronutrient and sugar consumption on growth and cognition. In the present study, we investigated the effects of micronutrients and sugar, alone and in combination, in a beverage on growth and cognition in schoolchildren. In a 2 × 2 factorial design, children (n 414, 6-11 years) were randomly allocated to consume beverages containing (1) micronutrients with sugar, (2) micronutrients with a non-nutritive sweetener, (3) no micronutrients with sugar or (4) no micronutrients with a non-nutritive sweetener for 8.5 months. Growth was assessed and cognition was tested using the Kaufman Assessment Battery for Children version II (KABC-II) subtests and the Hopkins Verbal Learning Test (HVLT). Micronutrients decreased the OR for Fe deficiency at the endpoint (OR 0.19; 95% CI 0.07, 0.53). Micronutrients increased KABC Atlantis (intervention effect: 0.76; 95% CI 0.10, 1.42) and HVLT Discrimination Index (1.00; 95% CI 0.01, 2.00) scores. Sugar increased KABC Atlantis (0.71; 95% CI 0.05, 1.37) and Rover (0.72; 95% CI 0.08, 1.35) scores and HVLT Recall 3 (0.94; 95% CI 0.15, 1.72). Significant micronutrient × sugar interaction effects on the Atlantis, Number recall, Rover and Discrimination Index scores indicated that micronutrients and sugar in combination attenuated the beneficial effects of micronutrients or sugar alone. Micronutrients or sugar alone had a lowering effect on weight-for-age z-scores relative to controls (micronutrients - 0.08; 95% CI - 0.15, - 0.01; sugar - 0.07; 95% CI - 0.14, - 0.002), but in combination, this effect was attenuated. The beverages with micronutrients or added sugar alone had a beneficial effect on cognition, which was attenuated when provided in combination.

Changes in Nigeria's enabling environment for nutrition from 2008 to 2019 and challenges for reducing malnutrition.

Key 2025 global nutrition targets are unlikely to be met at current rates of progress. Although actions necessary to reduce undernutrition are already mostly known, knowledge gaps remain about how to implement these actions in contextually appropriate ways, and at scales commensurate with the magnitude of the problem. This study describes the nutrition enabling environment in Nigeria, a country that contributes significantly to the global undernutrition burden, and identifies potential entry points for improving the enabling environment that could facilitate implementation and scale-up of essential intervention coverage. Study data were obtained from two sources: content analysis of 48 policies/strategies from agriculture, economic, education, environment, health, nutrition, and water/sanitation/hygiene sectors; and interviews at federal level (16) and in two states (Jigawa (10) and Kaduna (9) States). The study finds that aspects of the enabling environment improved between 2008 and 2019 and facilitated improvements in implementation of nutrition-specific and nutrition-sensitive interventions. Enabling environment components that improved included the framing of nutrition as a multisectoral issue, nutrition advocacy, political attention, evidence around intervention coverage, civil society involvement, and activity of nutrition champions. These factors have been especially important in creating and sustaining momentum for addressing malnutrition. While challenges remain in these aspects, greater challenges persist for factors needed to convert momentum into improvements in nutrition outcomes. Research and data that facilitate shared understanding of nutrition; improved multisectoral and vertical coordination; increased and improved delivery and operational capacity; and increased resource mobilization will be especially important for achieving future progress in nutrition in Nigeria.

Training to Build Nutrition Capacity in the Nigerian Agricultural Sector: Initial Assessment and Future Directions.

BACKGROUND: In response to calls to increase nutrition-sensitive agriculture (NSA), the Federal Ministry of Agriculture and Rural Development developed the Nigeria Agricultural Sector Food Security and Nutrition Strategy 2016-2025 (AFSNS). Capacity development activities to facilitate the AFSNS implementation subsequently commenced. OBJECTIVE: This study analyzed the processes and outputs of initial capacity development efforts, examined findings from the analysis using existing literature, and identified critical next steps for nutrition capacity development in the Nigerian agriculture sector. METHODS: The study reviewed documents including a proposal for nutrition training of agriculture sector actors, reports of meetings held among 6 resource persons who designed and/or delivered training, training reports, participants' pre- and posttraining assessments, and participants' training evaluation. Interviews were conducted with 2 resource persons involved in training design and delivery. Documents and interviews were coded and analyzed to identify emergent themes. Participants' pre- and posttests results were compared using paired t test in Stata 12.0. RESULTS: Knowledge and practice gaps were more extensive than had been anticipated. Training had some but limited effects on knowledge scores at the federal level. Modules addressing implementation practices had to be scaled down for participants to keep up with the learning pace. Existing literature indicates that such training would have been better planned as part of a broader sectoral nutrition workforce strategy, to facilitate greater tailoring of training to participants' job roles. CONCLUSION: Effective AFSNS implementation requires developing and operationalizing a comprehensive short-, medium- and long-term Agriculture Sector Nutrition Capacity Development Strategy for Nigeria.

Dietary Recommendations for Ethiopians on the Basis of Priority Diet-Related Diseases and Causes of Death in Ethiopia: An Umbrella Review.

Food-based dietary guidelines (FBDG) need to be evidence-based. As part of the development of Ethiopian FBDG, we conducted an umbrella review to develop dietary recommendations. Protein-energy malnutrition (PEM), deficiencies of vitamin A, zinc, calcium, or folate, cardiovascular diseases (CVD), and type 2 diabetes mellitus (T2DM) were selected as a priority. Systematic reviews were eligible if they investigated the impact of foods, food groups, diet, or dietary patterns on priority diseases. After a search, 1513 articles were identified in PubMed, Scopus, and Google Scholar published from January 2014 to December 2021. The results showed that 19 out of 164 systematic reviews reported the impact of diet on PEM or micronutrient deficiencies. Daily 30-90 g whole-grain consumption reduces risk of CVD and T2DM. Pulses improve protein status, and consuming 50-150 g/d is associated with a reduced incidence of CVD and T2DM. Nuts are a good source of minerals, and consuming 15-35 g/d improves antioxidant status and is inversely associated with CVD risk. A daily intake of 200-300 mL of milk and dairy foods is a good source of calcium and contributes to bone mineral density. Limiting processed meat intake to <50 g/d reduces CVD risk. Fruits and vegetables are good sources of vitamins A and C. CVD and T2DM risks are reduced by consuming 200-300 g of vegetables plus fruits daily. Daily sugar consumption should be below 10% of total energy to lower risk of obesity, CVD, and T2DM. Plant-based fat has favorable nutrient profiles and modest saturated fat content. The association of saturated fatty acids with CVD and T2DM is inconclusive, but intake should be limited because of the low-density lipoprotein cholesterol-raising effect. Plant-based diets lower risk of CVD and T2DM but reduce micronutrient bioavailability. The review concludes with 9 key dietary recommendations proposed to be implemented in the Ethiopian FBDG. This review was registered at PROSPERO (CRD42019125490).

The feasibility of implementing food-based dietary guidelines and food graphics in Ethiopia.

This study aimed to test the acceptability, cultural appropriateness, consumers' understanding, and practicality of the Ethiopian food-based dietary guideline's messages, tips, and food graphics. A qualitative study design was applied with focus group discussions and key informant interviews. Four different participant groups were included: 40 consumers, 15 high-level nutrition experts, 30 frontline community health extension workers (HEWs), and 15 agriculture extension workers (AEWs) to incorporate different stakeholder perspectives. Data collection was conducted using 7 focus group discussions (FGDs) and 30 key informant interviews (KIIs). Collected data were coded and analyzed using QSR International NVivo V.11 software. Most of the study participants were highly interested in implementing the dietary guidelines once these guidelines are officially released. Based on the participants' views, most of the messages align with the current nutrition education materials implemented in the country except the messages about physical activity and alcohol intake. However, participants suggested defining technical terms such as ultra-processing, whole grain, safe and balanced diet in simpler terms for a better understanding. Practicality, affordability, availability, and access to the market were the major barriers reported for adherence to the guidelines. To be more inclusive of cultural and religious beliefs, findings show that the guideline should address fasting and traditional cooking methods. In conclusion, the dietary guidelines were well received by most stakeholders. They are thought to be feasible once feedback on wording, affordability, availability, and access is considered in the messages, tips, and graphic designs.

Development of the Ethiopian Healthy Eating Index (Et-HEI) and evaluation in women of reproductive age.

Ethiopia announced its first food-based dietary guidelines (FBDGs) on 15 March 2022. The present study aims to develop and evaluate the Ethiopian Healthy Eating Index (Et-HEI) based on the FBDG. Data were collected from 494 Ethiopian women of reproductive age sampled from households in five different regions. The Et-HEI consists of eleven components, and each component was scored between 0 and 10 points, the total score ranging from 0 to 110, with maximum adherence to the FBDG. The Et-HEI score was evaluated against the Minimum Dietary Diversity for Women (MDD-W) and the probability of nutrient adequacy. The average Et-HEI score for women of reproductive age was 49 out of 110. Adherence to the recommendations for grains, vegetables, legumes, fat and oils, salt, sugar and alcohol contributed the most to this score. Most women had low scores for fruits, nuts and seeds, and animal-sourced foods, indicating low intake. The Cronbach's alpha coefficient, indicating the reliability of the Et-HEI to assess its diet quality, was 0⋅53. The low mean Et-HEI score agreed with a low mean score of the MDD-W (3⋅5 out of 10). Also, low nutrient adequacies confirmed poor adherence to nutrient-dense components of the FBDG. The Et-HEI was not associated with the intake of vitamin B12, vitamin C and calcium in this study population. Women who completed secondary school and above had relatively lower Et-HEI scores. The newly developed Et-HEI is able to estimate nutrient adequacy while also assessing adherence to the Ethiopian FBDG though there is room for improvement.

The state of food systems worldwide in the countdown to 2030.

This Analysis presents a recently developed food system indicator framework and holistic monitoring architecture to track food system transformation towards global development, health and sustainability goals. Five themes are considered: (1) diets, nutrition and health; (2) environment, natural resources and production; (3) livelihoods, poverty and equity; (4) governance; and (5) resilience. Each theme is divided into three to five indicator domains, and indicators were selected to reflect each domain through a consultative process. In total, 50 indicators were selected, with at least one indicator available for every domain. Harmonized data of these 50 indicators provide a baseline assessment of the world's food systems. We show that every country can claim positive outcomes in some parts of food systems, but none are among the highest ranked across all domains. Furthermore, some indicators are independent of national income, and each highlights a specific aspiration for healthy, sustainable and just food systems. The Food Systems Countdown Initiative will track food systems annually to 2030, amending the framework as new indicators or better data emerge.

Understanding drivers of stunting reduction in Nigeria from 2003 to 2018: a regression analysis.

Nigeria is a high burden country for stunting. Stunting reduction has been slow and characterized by unequal progress across the 36 states and federal capital territory of the country. This study aimed to assess the changes in prevalence of stunting and growth determinants from 2003 to 2018, identify factors that predicted the change in stunting, and project future stunting prevalence if these predicted determinants improve. Trend and linear decomposition analyses of growth outcomes and determinants were conducted using 2003, 2008, 2013, and 2018 Nigeria Demographic and Health Survey data. Pooled data included 57,507 children 0 to 59 months old. Findings show that stunting and severe stunting significantly reduced from 43 to 37% and 23% to 17%, respectively (p < 0.001), between 2003 and 2018. Disturbingly, height-for-age z-scores at birth significantly decreased, indicating risks of potential future stunting increase. Improvements in nine stunting determinants (maternal body mass index, maternal height, ≥ 4 antenatal care visits, health facility delivery, reduced child illnesses, asset index, maternal education, paternal education, and preceding birth interval) predicted stunting reductions in children 0-59 months. Few of these nine determinants improved in subpopulations with limited stunting progress. Intra-sectoral and multisectoral coordination were potentially inadequate; 12% of children had received all of three selected health sector interventions along a continuum of care and 6% had received all of six selected multisector interventions. Forward looking projections suggest that increased efforts to improve the nine predictors of stunting change can reduce under-five stunting in Nigeria to ≤ 27% in the short term.

Challenges to joint planning, monitoring, and evaluation for nutrition-sensitive agriculture in Ethiopia: an exploratory qualitative study.

Background: Nutrition-sensitive agriculture is an effective multi-sectoral approach to address the underlying causes of malnutrition. However, successful implementation requires the involvement of different sectors to jointly plan, monitor, and evaluate key activities, which is often challenged by contextual barriers. Previous studies in Ethiopia have not adequately explored these contextual barriers. Hence, the current study aimed to qualitatively explore the challenges to joint planning, monitoring, and evaluation for nutrition-sensitive agriculture among sectors in Ethiopia. Methods: A qualitative exploratory study was conducted in Tigray and Southern Nations, Nationalities, and Peoples (SNNP) of Ethiopia regional states in 2017. Ninety-four key informants were purposively selected from government agencies primarily in health and agriculture, from local (kebele) to national levels, and ranging from academic organizations, research institutions, and implementing partners. Researchers developed a semi-structured guide and conducted key informant interviews which were audiotaped, transcribed verbatim in local language, and translated to English. All transcriptions were imported into ATLAS.ti Version 7.5 software for coding and analysis. The data analysis followed an inductive approach. Transcriptions were coded line by line; then similar codes were grouped into categories. Subsequently, non-repetitive themes were identified from the categories using thematic analysis methodology. Results: The following themes were identified as challenges that hinder joint planning, monitoring, and evaluation to link nutrition to agriculture: (1) limited capacity, (2) workload in home sector (agriculture or nutrition), (3) lack of attention to nutrition interventions, (4) inadequate supportive supervision, (5) problematic reporting system, and (6) weak technical coordinating committees. Conclusions and recommendations: Gaps in human and technical resources, limited attention from different sectors, and absence of routine monitoring data hindered joint planning, monitoring, and evaluation activities for nutrition-sensitive agriculture in Ethiopia. Short-term and long-term training for experts and intensification of supportive supervision may address gaps in capacity. Future studies should address whether routine monitoring and surveillance in nutrition-sensitive multi-sectoral activities provides long-term improvement in outcomes.

Sustainable food systems and nutrition in the 21st century: a report from the 22nd annual Harvard Nutrition Obesity Symposium.

Food systems are at the center of a brewing storm consisting of a rapidly changing climate, rising hunger and malnutrition, and significant social inequities. At the same time, there are vast opportunities to ensure that food systems produce healthy and safe food in equitable ways that promote environmental sustainability, especially if the world can come together at the UN Food Systems Summit in late 2021 and make strong and binding commitments toward food system transformation. The NIH-funded Nutrition Obesity Research Center at Harvard and the Harvard Medical School Division of Nutrition held their 22nd annual Harvard Nutrition Obesity Symposium entitled "Global Food Systems and Sustainable Nutrition in the 21st Century" in June 2021. This article presents a synthesis of this symposium and highlights the importance of food systems to addressing the burden of malnutrition and noncommunicable diseases, climate change, and the related economic and social inequities. Transformation of food systems is possible, and the nutrition and health communities have a significant role to play in this transformative process.

Perspective: Food Environment Research Priorities for Africa-Lessons from the Africa Food Environment Research Network.

Over the last 2 decades, many African countries have undergone dietary and nutrition transitions fueled by globalization, rapid urbanization, and development. These changes have altered African food environments and, subsequently, dietary behaviors, including food acquisition and consumption. Dietary patterns associated with the nutrition transition have contributed to Africa's complex burden of malnutrition-obesity and other diet-related noncommunicable diseases (DR-NCDs)-along with persistent food insecurity and undernutrition. Available evidence links unhealthy or obesogenic food environments (including those that market and offer energy-dense, nutrient-poor foods and beverages) with suboptimal diets and associated adverse health outcomes. Elsewhere, governments have responded with policies to improve food environments. However, in Africa, the necessary research and policy action have received insufficient attention. Contextual evidence to motivate, enable, and create supportive food environments in Africa for better population health is urgently needed. In November 2020, the Measurement, Evaluation, Accountability, and Leadership Support for Noncommunicable Diseases Prevention Project (MEALS4NCDs) convened the first Africa Food Environment Research Network Meeting (FERN2020). This 3-d virtual meeting brought researchers from around the world to deliberate on future directions and research priorities related to improving food environments and nutrition across the African continent. The stakeholders shared experiences, best practices, challenges, and opportunities for improving the healthfulness of food environments and related policies in low- and middle-income countries. In this article, we summarize the proceedings and research priorities identified in the meeting to advance the food environment research agenda in Africa, and thus contribute to the promotion of healthier food environments to prevent DR-NCDs, and other forms of malnutrition.

Point-of-use micronutrient fortification: lessons learned in implementing a preschool-based pilot trial in South Africa.

This current pilot trial assessed the feasibility of implementing a point-of-use (PoU) micronutrient fortification in preschool settings. Preschool children (n = 151) aged 36-79 months were randomized into intervention (n = 76) and control (n = 75) groups, both receiving breakfast maize-porridge with added micronutrient or placebo powder for 52 school days. Process evaluation and early childhood development indicators were used to assess trial feasibility. Process evaluation results showed that the implementation components were feasible and could be delivered with high fidelity. The improvement in hemoglobin concentration in intervention and control groups were not significantly different (P = 0.250). There was medium likelihood for practical significance for the two global cognitive scores assessed: non-verbal index (intervention effects: 7.20; 95% confidence interval: 2.60, 11.81; P = 0.002, effect size: 0.55) and mental processing index (intervention effects: 2.73; 95% confidence interval: 0.25, 5.70; P = 0.072, effect size: 0.36) on the Kaufman Assessment Battery for Children, Second Edition. The lessons from this trial could help in planning/implementing future PoU micronutrient fortification trial among South African preschool children.

Traditional and Indigenous Fruits and Vegetables for Food System Transformation.

Fruit and vegetable consumption is recommended in numerous food-based dietary guidelines and forms a key recommendation in many international statements related to healthy diets. There are thousands of fruit and vegetable species from which to choose, but despite this abundance from nature, populations in most countries neither produce nor consume the recommended daily amounts of fruits and vegetables. There is enormous potential to better incorporate the wealth of diverse fruit and vegetable species and varieties into food systems. Known and preserved by indigenous communities, these hidden food treasures can foster collaborative research and learning. This perspective from the Task Force on Traditional and Indigenous Food Systems and Nutrition of the International Union of Nutritional Sciences (IUNS) highlights 5 key actions that can be taken by individuals, communities, and nations to reshape dialogue about traditional and indigenous fruits and vegetables to benefit people and planetary ecosystems.
