Micronutrient-rich Foods Research Articles

Evaluating the roles of food matrix, lipid micronutrients and bioactives in controlling postprandial hypertriglyceridaemia and inflammation.

Lipids play an important role in human nutrition. Although adequate lipid consumption is necessary for an optimal functioning of the human body, overconsumption of saturated fatty acids can lead to postprandial hypertriglyceridaemia, which triggers the development of atherosclerosis. Important parameters that impact postprandial lipaemia and inflammation are related to the matrix structure and the fat-soluble micronutrient profile of ingested foods/lipids, but the specific effect of these parameters should be further studied, as most of the available studies evaluate their effect at fasting state. This review specifically explores the effects of food structure and fat-soluble micronutrients, from either micronutrient-rich foods or supplements, on postprandial hypertriglyceridaemia and inflammation. The review also highlights the potential of emerging biomarkers such as miRNAs or circulating microvesicles, as an alternative to the widely use biomarkers (e.g. low-density lipoproteins or blood concentration of pro-inflammatory cytokines), to identify inflammation associated with postprandial hypertriglyceridaemia at early stages.

Understanding Behavioral Drivers of Iron and Folic Acid Supplementation and Vitamin A- and Iron-Rich Food Consumption among Women and Adolescent Girls in Niger.

This study examined drivers and barriers to iron and folic acid (IFA) supplementation and consumption of iron- and vitamin A-rich foods among women of reproductive age (WRA) and adolescent girls in Niger. This was an exploratory qualitative study using focus group discussions and semi-structured interviews. This study was conducted in the rural areas of three districts in Maradi and Zinder regions of southern Niger. The study included a purposive sample of 56 WRA (15-49 years), 34 non-pregnant adolescent girls (10-14 years), 105 family members and community leaders, 32 health workers, and 12 national and regional level stakeholders. Respondents demonstrated widespread knowledge of recommendations for IFA during pregnancy and had positive attitudes toward supplements. However, supply barriers were significant, and adherence was limited by side effects, among other constraints. Despite knowledge about and positive attitudes towards micronutrient source foods, respondents reported that limited food access was an overriding constraint to increasing consumption. WRA were seen as nutritionally vulnerable, however husbands were often not able to provide sufficient nutritious food and there was a cultural expectation that wives serve themselves food last. Adolescent girls were not seen as nutritionally vulnerable and there was little family support for their consumption of nutritious foods. Projects should work with local actors to develop multi-pronged solutions that address supply and access barriers for IFA and micronutrient-rich foods and to improve social support for nutrition.

Association between micronutrient intake and cognitive performance of school-aged children attending selected private schools in Lagos State

Background: It has been reported that the academic performance of school-aged children has been on the decline in recent years. Feeding pattern determines micronutrient consumption and plays an important role in cognitive performance. Objectives: This research assessed the micronutrient consumption, feeding pattern, and cognitive performance of school-aged children in selected private schools in Lagos State. Methods: The socio-demographic characteristics of the parents and children, knowledge of parents on micronutrients, feeding pattern of the children, and identifying micronutrient-rich food among consumed foods were obtained using a semi-structured questionnaire. The micronutrient intake was assessed using twenty-four-hour dietary recall and the cognitive performance of the respondents was evaluated with structured questions from Slosson’s intelligence test revised third edition after which the micronutrient consumption was correlated against overall cognitive performance using Pearson’s multiple correlation range test. Results: The results indicated that the feeding pattern of the children showed that 51.3% were fed three times a day, 47.3% took snacks at least once a day and more than half (52.0%) took fruits and vegetables once a day. The micronutrient-rich foods among consumed foods were identified and they include efo and egusi, ewedu, okro, apple, orange, and milk, among others. There was a negative correlation (p<0.05) between micronutrient consumption and cognitive performance among the students studied. Conclusion: This study concludes that an increase in micronutrient consumption alone does not increase cognitive performance.

Food-sourcing from on-farm trees mediates positive relationships between tree cover and dietary quality in Malawi

Food security policies often overlook the potential of trees to provide micronutrient-rich foods. Here, through causal mediation analysis, we show the positive effect of tree cover on micronutrient adequacy, explained by people sourcing food from on-farm trees. Detailed survey data (n = 460 households with repeated surveys) from Malawi were linked to high-resolution (3 m) tree-cover data to capture forest and non-forest trees. Our findings support integrating nutrition and landscape restoration policies.

Evaluation of micronutrient and nutritional status among preschool children in Jordan: results from a Nationwide survey.

Jordan faces various malnutrition challenges, including undernutrition, micronutrient deficiencies, overweight, obesity, and diet-related non-communicable diseases. The country has shifted from issues of undernutrition to rising rates of overweight and obesity, while still dealing with micronutrient deficiencies. The 2010 national survey revealed high rates of iron and vitamin D deficiencies among preschool children, with about 20% experiencing vitamin A deficiencies. The goals of the 2019 Jordan National Micronutrient & Nutrition Survey (JNMNS) include assessing feeding practices of infants and young children, determining the frequency of consuming micronutrient-rich foods, evaluating causes of anemia, assessing the health status of specific subgroups, and comparing findings to the 2010 survey. JNMNS 2019 was a comprehensive national cross-sectional survey structured across four strata. Within each stratum, 40 primary sampling units were chosen in proportion to their size based on the 2015 Jordan census. Subsequently, the Department of Statistics conducted household listings in each PSU. Separate response rates were assumed for households and target groups, encompassing interviews, anthropometric measurements, and specimen collection. The survey aimed to collect data from 2,210 households, including interviews and anthropometry for 1,232 preschool children, with blood samples obtained from 992 of them. The findings revealed no severe anemia cases, but 11% of preschoolers aged 12-59 months were anemic. Iron deficiency affected 22.4%, with 5% having iron deficiency anemia. Vitamin D deficiency increased to 22.9% in 2019. Stunting and wasting rates improved slightly to 6.3 and 0.1%, respectively. Overweight and obesity rates remained stable at 6.2 and 2.1%. Anemia decreased by 5-6%, but iron deficiency rose by 7%. Vitamin A deficiency decreased, but iron deficiency anemia remained largely unchanged. Undernutrition was rare, but vitamin D deficiency affected 27.7% of preschoolers, impacting growth and immunity. Iron deficiency, affecting 25% of children, poses a risk to cognitive development. Overweight or obesity affected 9% of children, a medium public health issue according to the WHO. While malnutrition rates are low, the persistent issues of vitamin D deficiency, iron deficiency, and childhood obesity require focused attention. The study highlights ongoing nutritional challenges among Jordanian preschoolers. Although severe anemia was rare, 11% were anemic, and 22.4% had iron deficiency, including 5% with iron deficiency anemia. Vitamin D deficiency affected 22.9%, impacting growth and immunity. While stunting and wasting improved, childhood overweight and obesity rates remained steady. Anemia decreased, but iron deficiency rose by 7%. Despite reduced vitamin A deficiency, stable iron deficiency anemia rates indicate ongoing concerns. Overall, undernutrition is uncommon, but vitamin D and iron deficiencies, along with childhood obesity, need sustained attention and targeted interventions to improve children's health in Jordan.

Integrating nutrition in the Sasakawa Africa Association extension services: Knowledge, attitude and practices among smallholder farmers

This survey aimed to establish nutrition-related knowledge, attitudes and practices, and to observe how gender influences household food-related decision-making processes in the Sasakawa Africa Association (SAA) intervention areas in the Oromia and Southern Nation Nationalities and People regions of Ethiopia. The findings would inform implementation of communication for nutrition social and behaviour change among small-holder farmers as part of the SAA corporate strategy on nutrition-sensitive agriculture. The study population was smallholder farmers supported by SAA from which 311 respondents were selected through multistage sampling. Data were collected via a mixed methods approach consisting of a household survey, focus group discussions (FGDs) and key informant interviews (KIIs). Quantitative data were analysed using descriptive statistics while qualitative data was analysed using a narrative and content approach. The study focused on knowledge, attitudes and practices related to production and consumption of micronutrient-rich foods. Majority (59.5%) of the respondents were male. Men were the main decision makers on staple or commercial food crop production and proportion of produced crops to be consumed at home or sold in the market. Women mainly made decisions regarding production and consumption of fruits and vegetables, intra-household food distribution, preservation and storage. There was a lack of knowledge on iron and vitamin A fortified or biofortified sources of food. Nearly three quarters (72%) of women did not meet the minimum dietary diversity for women, a proxy indicator of adequacy of micronutrient intake and diet quality. The mean dietary diversity score was 3.8 with animal source foods being the least consumed. Not having sufficient money to buy food, unavailability of different food groups and poor intra-household food distribution were among the key reasons for lack of diverse diets. Majority of the respondents were aware of the importance of production and consumption of micronutrient-rich foods. However, there was a gap in practice and awareness about biofortified and fortified foods. While most of the respondents had produced fruits and vegetables in home gardens in the three months prior to this survey, more than half (54%) of the respondents thought it was not likely that they would produce fruits and vegetables for home consumption. More targeted nutrition campaigns are required to increase the ability of small-holder farmers to adopt best practices while reducing the barriers associated with access and consumption. Promotion of fruit and vegetable production in home gardens could be considered as option for improving household dietary quality as well as empowering women to make more decisions.

Considerations for Correction of Micronutrient Deficiencies Through Supplementation in Pregnant Women and Children Under-5 in Latin America.

Micronutrient deficiencies in Latin America are a public health concern, nonetheless, lack of information still exists in many countries, so that the true magnitude of the problem remains uncertain. To summarise experiences that can inform the development of policies and programs to address micronutrient deficiencies throung supplementation in pregnant women and chlidren under five years of age in Latin American. Review of the most evidence on the effects of micronutrients supplementation, focusing on pregnant women and children under five years of age. Certain population groups, as women of reproductive age and children under 2 years of age, are at increased risk for deficiency due to their high micronutrient requirements. This is compounded by the limited access to micronutrient-rich foods for many people living in vulnerable situations. Micronutrient supplementation is an effective intervention to prevent and treat deficiency and to mitigate its adverse effects on health, nutrition, and pregnancy outcomes in micronutrient-deficient populations. The potential benefits of supplementation programs, however, are realized only when they reach those who have the potential to benefit, that is, with inadequate intakes of micronutrients from dietary sources, and when the quality of design and delivery of the programs aresufficient to reach that population timely, regularly, and effectively to enable and motivate consumption. Several resources and experiences exist that can help favor the development of programs that can realize this biological and programmatic potential. There is need for continuous efforts to augment coverage and achieve results that can translate into economic benefits for individuals, families, and nations.

Stakeholder-driven transformative adaptation is needed for climate-smart nutrition security in sub-Saharan Africa

Improving nutrition security in sub-Saharan Africa under increasing climate risks and population growth requires a strong and contextualized evidence base. Yet, to date, few studies have assessed climate-smart agriculture and nutrition security simultaneously. Here we use an integrated assessment framework (iFEED) to explore stakeholder-driven scenarios of food system transformation towards climate-smart nutrition security in Malawi, South Africa, Tanzania and Zambia. iFEED translates climate–food–emissions modelling into policy-relevant information using model output implication statements. Results show that diversifying agricultural production towards more micronutrient-rich foods is necessary to achieve an adequate population-level nutrient supply by mid-century. Agricultural areas must expand unless unprecedented rapid yield improvements are achieved. While these transformations are challenging to accomplish and often associated with increased greenhouse gas emissions, the alternative for a nutrition-secure future is to rely increasingly on imports, which would outsource emissions and be economically and politically challenging given the large import increases required.

A Landscape of Micronutrient Dietary Intake by 15- to 65-Years-Old Urban Population in 8 Latin American Countries: Results From the Latin American Study of Health and Nutrition.

Latin American countries have shifted from traditional diets rich in micronutrients to a Westernized diet rich in high energy-dense foods and low in micronutrients. This study aimed to determine the prevalence of adequate micronutrient intakes in urban populations of 8 Latin American countries. Micronutrient dietary intake data were collected from September 2014 to August 2015 from 9216 men and women aged 15.0 to 65.0 years living in urban populations of 8 Latin American countries. Dietary intake was collected using two 24-hour recalls on nonconsecutive days. Micronutrient adequacy of intake was calculated using the Estimated Average Requirement cut-off method. In general terms, the prevalence of inadequate intake of thiamine, riboflavin, niacin, folate, cobalamin, iron, phosphorus, copper, and selenium ranged from 0.4% to 9.9%. In contrast, the prevalence of inadequacy of pyridoxine, zinc, vitamin C, and vitamin A ranged from 15.7% to 51.5%. The nutrients with a critical prevalence of inadequacy were magnesium (80.5%), calcium (85.7%), and vitamin D (98.2%). The highest prevalence of inadequate intakes was observed in the low educational level, participants with overweight/obesity, in men, and varies according to socioeconomic status. There is an urgent need to define direct regional actions and strategies in Latin America aimed at improving micronutrient adequacy, either through staple food fortification programs, agronomic biofortification, or food policies that facilitate economic access to micronutrient-rich foods.

Deteriorating complementary feeding practices and dietary quality in Jordan: Trends and challenges.

Quality complementary feeding (CF) of infants and young children is key to their growth and development. But in Jordan, providing appropriate CF remains a challenge. This study assesses trends in infant and young child feeding (IYCF)practices, and consumption by infants and young children aged 6-23 months of breast milk substitutes (BMSs), sugar-sweetened beverages (SSBs), and micronutrient-rich foods in Jordan from 1990 to 2017. We combined dietary data on infants and young children from six Demographic and Health Surveys (DHS)(n = 14,880 children) to compute IYCF indicators. The latter included minimum dietary diversity (MDD),minimum meal frequency (MMF),and minimum acceptable diet (MAD),as well as intake of micronutrient-rich foods and food groups, specific SSBs, and infant formula. We conducted trend analyses using logistic regression models adjusted for child's age in month, child age squared, governorates, urban/rural residence, mother's educational attainment, and household wealth quintiles. We found that the proportion of consumption of micronutrient-rich food groups declined significantly between 1990 and 2017, with fewer infants and young children consuming eggs (OR = 0.39, p ≤ 0.001, 2002 reference), meat, poultry, and fish (OR = 0.25, p ≤ 0.001, 2002 reference), dairy (OR = 0.59, p ≤ 0.001, 2002 reference) and Vitamin A-rich fruits and vegetables (OR = 0.66, p ≤ 0.001, 2002 reference). Conversely, there was increased use of BMSs and sugar-sweetened juices that paralleled a decline in the share of infants and young children meeting appropriate CF practices and consuming micronutrient-rich foods and food groups. By 2017, children aged 6-23 months were significantly less likely to meet MDD, MMF, and subsequently MAD; the odds of consuming BMSs were almost three times the reference (OR = 3.8, p ≤ 0.001, 1990 reference), as werethe odds of consumingsugar sweetened juices (OR = 3.63, p ≤ 0.001, 1990 reference). Food insecurity and undernutrition are low in Jordan; however, overweight and obesity rates are increasing concurrently as are micronutrient deficiencies. This highlights the need for policymakers to address factors at individual and household levels (behaviours and practices) as well as environmental issues (increasing access to unhealthy and ultraprocessed foods).

Knowledge, attitude and practice towards malnutrition and micronutrient deficiency among male and female farmers in Ethiopia

BackgroundDespite a large body of literature on the nexus between knowledge, attitude and practice towards nutrition and gender, this nexus is likely to vary and is not clear in many societies, such as Ethiopia.ObjectivesThe study aimed to analyze the level of gender-based knowledge, attitude, and practice towards malnutrition and micronutrient deficiency using primary data collected from two regional states in Ethiopia.MethodsQualitative and quantitative data collection approaches were used. Qualitative data were analyzed using a narrative and content approach. Quantitative data were analyzed using descriptive statistics.ResultsResults indicate that female are generally more adept than male at identifying the symptoms of malnutrition. However, concerning vitamin A and iodine food types and its deficiency, male respondents had relatively better knowledge and consumption practice than female. Results show that there is very little awareness about biofortified and fortified foods. When we rate respondents, male had a relatively better understanding about fortified foods than their female counterparts.ConclusionFindings can support development agents working to improve nutrition in Ethiopia to focus on improving community knowledge and perception of biofortified and fortified foods to improve diet quality through increased micronutrient intake. The majority of the respondents were aware of the importance of consuming micronutrient rich foods and had a positive attitude towards them. However, there is still a gap in practice. It may therefore require more targeted campaigns to increase the ability of community members to adopt best practices while reducing barriers to consumption of nutritious diet.

Dietary patterns in North and South India: a comparison with EAT-Lancet dietary recommendations.

Environmentally sustainable diets are represented in the EAT-Lancet recommendations developed by the Lancet Commission on Planetary Health in 2019. Very few studies have compared Indian diets with the EAT-Lancet recommendations. The present study performed such a comparison using primary dietary consumption data from adults in north and south India. Data from 8762 adults (52.4 ± 11.7 years) residing in Sonipat and Vizag India were collected on sociodemographic characteristics, wealth index (household assets) and dietary intake (food frequency questionnaire: nine food groups). The quantity consumed and energy from each food group was compared with the EAT-Lancet recommendations. We investigated the likelihood of deficit or excess in consumption compared to the EAT-Lancet recommendations by different sociodemographic factors. Half of the participants were women and half resided in rural areas. Vegetables and fruits were consumed in lower quantity, whereas dairy and added fats were consumed in higher quantity than recommended by the EAT-Lancet recommendations. For whole grains, female gender and poorest wealth index were the factors associated with deficit or no consumption, whereas, for vegetables and fruits, it was poorest wealth index and residence in rural areas (p < 0.05, all). Rural residence and poorest wealth index were associated with excess consumption of dairy and added fats (p < 0.05, all). The diets of the study participants were mainly plant-based, and high in dairy but lacking in nutrient-rich foods such as vegetables and fruits. Appropriate policy actions for making healthy sustainable diets and micronutrient-rich foods available and affordable to all with a particular focus on the poor and rural populations are warranted.

What Do United States Adolescents Eat? Food Group Consumption Patterns and Dietary Diversity from a Decade of Nationally Representative Data

BackgroundAlthough the importance of adolescent nutrition has gained attention in the global nutrition community, there is a gap in research focused on adolescent dietary diversity and food group consumption. ObjectivesThis study aimed to characterize population-level food group consumption patterns and quantify the extent of dietary diversity among United States adolescents using a large nationally representative sample of adolescents aged 10–19 y. MethodsWe used 24-h dietary recall data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2018 to construct the 10 food groups comprising the minimum dietary diversity for women (MDD-W) indicator and estimated the prevalence of intake of each food group. A composite metric adolescent dietary diversity score (ADDS) was derived for each adolescent where 1 point was awarded per food group. Both population scores and the distribution of individual scores were estimated. Differences in proportions of food groups consumed across sociodemographic categories were tested using the Rao–Scott χ2 test, and pairwise comparisons were expressed as population prevalence differences and prevalence ratios. ResultsFood group consumption patterns were very similar across 2 d of dietary recall but varied significantly by sex, race/ethnicity, and income status. The food groups with the highest prevalence of consumption were grains, white roots, and tubers (∼99%), milk products (∼92%), and meat, poultry, and fish (∼85%), whereas <15% of adolescents consumed key micronutrient-dense foods, such as vitamin A–rich fruits and vegetables and dark green vegetables. The mean ADDS was 4.69, with modest variation across strata. ConclusionsOn average, United States youth consumed fewer than 5 food groups on a given day. The lack of dietary variety and relatively low prevalence of consumption of several micronutrient-rich plant-based foods could pose a risk for adolescents’ ability to achieve micronutrient adequacy in the United States.

Dietary diversity and micronutrient rich food consumption patterns among women of reproductive age in Kayunga and Jinja, Uganda

The diets of women of reproductive age (WRA) in low-income countries have been reported to be inadequate in micronutrients which lead to undernutrition. The foods commonly consumed by women are usually starchy plant-based cereals, roots and tubers which are limited in micronutrients. Amidst Uganda producing abundance of fruits and vegetables which are sources of micronutrients, it seems that consumption patterns have a role to play. The aim of this study was, therefore, to evaluate the prevailing diets of women of reproductive age in Kayunga and Jinja districts. A cross- sectional study was conducted in August 2019. Four hundred and ninety two (492) women of reproductive age were purposively selected from the two sub-counties to participate in the study. A 24-hour recall questionnaire was used estimate the women’s minimum dietary diversity for women of reproductive age (MDD-W) and it is contribution towards meeting micronutrient requirements. Means were computed for continuous variables, while proportions were computed for the descriptive variables that were placed under different themes and categories. Results revealed that more than 80% of women did not achieve the minimum dietary diversity. Less than 50% of the women consumed foods from plant and animal protein rich food groups that are major sources of iron, zinc, calcium, and vitamin B-12. In addition, more than 80% of the women’s diets lacked vitamin A- rich fruits and vegetables and dark green leafy vegetables which are the rich food group sources for vitamin A and folate. Therefore, over 80% of the women in Kayunga and Jinja districts did not obtain the required micronutrients for their good health and that of their children and thus, are at risk of poor health due to micronutrient deficiencies. It is recommended to have nutrition education coupled with demonstrations to mothers on how to prepare a diversified diet. Key words: Women, dietary diversity, food groups, micronutrients, nutrient adequacy

Determinants of uptake of biofortified crop varieties by smallholder farmers in Uganda

Hunger and malnutrition can be said to be one of the important global problems that have recently been exacerbated by climate change and environmental degradation. Meanwhile, an estimated two billion people suffer from micronutrient malnutrition, mostly due to low intake of vitamins and minerals such as iron and zinc. Biofortification, an agricultural technology that can increase the micronutrient content of staples, may confer large benefits to rural families and poor children with limited access to expensive high-quality foods. Possible pathways include own-consumption when directly consumed, the income pathway when they are sold and/or the food price pathway when they increase the availability of micronutrient-rich foods in the market place. This research aims to understand the factors associated with the uptake of biofortified crop varieties (BCV) among smallholder farmers in Uganda and derive policy information to support their accelerated uptake. The analysis used two waves of panel data consisting of 6,400 observations collected from 6 districts in Uganda as part of the Feed the Future (FtF) innovation laboratory for nutrition. Descriptive analysis was used to help discern the differences between adopters and non-adopters of BCV. Double hurdle regression analysis was used to understand the factors associated with adoption and the intensity of adoption of biofortified crop varieties. Descriptive results reveal significant differences between adopters and non-adopters of BCV. Double hurdle regression analysis results indicate that the primary determinants of uptake of biofortified crop varieties include geographical location, extension staff visits, household size, and mobile phone ownership. Other important factors associated with the adoption of BCV include the amount of land owned by the household. Results suggest that extension staff visits, and mobile phone ownership were important sources of information for rural households that appear to drive the decision to adopt biofortified crop varieties. Meanwhile, household size, regional location of the household and total land owned were important motivators in adopting BCV technology. From the present analysis, it was not possible to clearly discern the key drivers of the intensity of adoption of biofortified crop varieties among smallholder households in Uganda.

Determinants of Maternal Diet Quality in Winter in the Kyrgyz Republic.

Diet quality influences maternal health and nutrition from preconception through pregnancy and lactation, as well as infant health and nutrition. Women are vulnerable to poor nutrition given their increased nutrient requirements during the prenatal period through the first 2 years postpartum. Minimum diet diversity among women, a good predictor of adequate micronutrient intake, is often used as a proxy for diet quality. The Kyrgyz Republic is experiencing a triple burden of malnutrition-stunting in children, overweight and obesity in women, and micronutrient deficiencies and anemia in both women and children. In this study, we assessed factors associated with the quality of maternal diets in winter when micronutrient-rich foods may be more difficult to access due to scarcity and price. We conducted secondary data analysis from a survey conducted in the winter of 1,359 mothers of children aged younger than 2 years. Women were asked about the types of foods they stored and preserved in the fall and whether any remained in winter. After controlling for maternal characteristics, household size, main source of income, and region (including urban and rural), women with preserved food remaining at the time of the survey, who stored more than 4 different types of food in the fall, and who lived in Jalal-Abad oblast were more likely to have consumed a minimally diverse diet. Where seasonality affects food availability, promoting culturally appropriate home processing of a variety of foods in the fall and increased market access may improve diet diversity in winter.

Effect of 12 weeks consumption of palm weevil larvae and orange-fleshed sweet potato fortified biscuit on nutritional status and cognitive performance of school children in Kumasi, Ghana

Micronutrients are important for improving the physical growth and cognition of school-aged children. Food fortification strategies using locally available and consumed micronutrient rich foods such as edible insects can be cost effective and sustainable in improving nutritional and cognitive outcomes in school children. The study evaluated the impact of biscuits fortified with palm weevil larvae and orange-fleshed sweet potato on cognitive performance and nutritional status of school children from low income families in an urban setting in Ghana. A 12-week randomized, blinded controlled trial was conducted. 102 school children aged 6-11 years were assigned to consume either the fortified biscuits or non-fortified biscuits. Raven’s cognition test, anthropometrics, hematological and biochemical parameters were assessed at baseline and at the end of the study. After 12 weeks of intervention, there were no statistically significant differences in the means of the nutritional outcomes and cognitive performance between the treatment and control groups (p&gt;0.05). However, significant increase in mean levels of serum ferritin (Baseline: 26.15 ± 18.42 µg/L, Endline: 42.63 ± 19.54 µg/L, mean increase: +16.48 µg/L, p=0.001), weight-for-age (Baseline: -0.37 ± 0.97, Endline: -0.11 ± 0.91, mean increase: +0.26, p&lt;0.0001), and Raven’s cognition test score (Baseline: 14.22 ± 4.93, Endline: 16.35 ± 4.40, mean increase: +2.13, p&lt;0.0001) were observed within the treatment group compared to the control group where significant increase was observed in only the Ravens cognition test score (Baseline: 14.79 ± 4.57, Endline: 15.95 ± 5.32, mean increase: +1.16, p&lt;0.029). Moreover, the mean increase in cognition score was higher in intervention (+2.13) than control (+1.16) children. Results from binary logistic regression showed that although statistically insignificant, children in the treatment group had lower odds of iron deficiency (AOR= 0.7, p = 0.545, 95%CI= 0.2-2.4). In conclusion, consumption of the fortified biscuit significantly improved serum ferritin and weight-for-age in the school-aged children within the treatment group. Improvement in cognitive test score was also higher in the treatment group than the control group. Key words: Fortified biscuit, cognition, micronutrients, school children, palm weevil larvae, insects

A Review of Food-Based Intervention Strategies for Improving Micronutrient Status and Health During Childhood

Micronutrient deficiencies, especially those of iron, vitamin A, zinc and iodine are most common around the world, particularly in children and adolescents. These deficiencies can be prevented through nutrition education and consumption of a healthy diet containing diverse foods, as well as food fortification and supplementation. Available evidence has suggested that instead of synthetic supplements, dietary diversification and modification by including micronutrient-rich foods with appropriate food preparation methods to increase bioavailability, is an effective strategy to treat deficiency state. Therefore, a literature search was conducted for studies i) developing nutritious food products and ii) evaluating food intervention effects. Twelve studies described formulation of snacks/recipes using micronutrient-rich foods and proper cooking methods to enhance bioavailability. Twenty-four food-based intervention trials in children (6 months–16 years) reported increase in micronutrient intakes. Of these, 4 studies reported improvements in all growth parameters except one study showing no improvement in height z scores, 6 studies observed positive changes in bone and muscle development, whereas one study found no effect of dairy intervention on bone mass accrual, 6 studies noted increases in biochemical parameters and/or decrease in infections, whereas two showed no change in serum levels, 4 studies noticed improved cognitive/scholastic performance. Thus, available literature indicates that supplementing snacks or small meals with high bioavailable micronutrient contents significantly increases micronutrient intake and help improving growth and development of children. Further research is warranted to devise food-based strategies for improving micronutrient quality of diets to lower the associated health risks.

Formulation, process optimization, and quality evaluation of barnyard millet ( Echinochloa frumentacea )‐based ready‐to‐eat ( RTE ) extruded snack

COVID-19 pandemic has increased the demand for antioxidant and micronutrient-rich foods that are easy to prepare, consume, and require less handling. In this research, we worked on the development of nutritious extruded snack made from barnyard millet, defatted soy flour, Indian gooseberry powder, and rice flour. Box–Behnken Design of Response Surface Methodology was utilized to determine the influence of process variables viz; blend ratio of barnyard millet and defatted soy flour, extruder barrel temperature, and Indian gooseberry powder on nutritional and organoleptic properties of snack. Optimized extruded snack were attained at blend ratio (6:1), barrel temperature (115°C), and Indian gooseberry (12.25 g/100 g of total flour). Extruded snack presented good overall acceptability along with high fiber (16.84 g/100 g), protein (18.91 g/100 g), total phenol (67.51 mg GAE/100 g), and total flavonoid (153.61 mg RE/100 g) content. Microbial analysis indicates that extruded snack can be stored for up to 60 days without microbial contamination. Novelty impact statement The pandemic has made people refocus on the foods that are nutritious, yet take less time to prepare and handle. In the present research, we explored the use of locally available and low-cost barnyard millet and defatted soy flour coupled with Indian gooseberry powder—a rich source of antioxidants and rice flour for the preparation of nutritious snack. Extrudates developed with a higher blend ratio at higher barrel temperature and enriched with Indian gooseberry content displayed excellent nutritional, bioactive, and dimensional characteristics. The study will help formulate extruded snack with high protein, antioxidants, as well as fiber content.

Social assistance programme impacts on women's and children's diets and nutritional status.

Investments in social assistance programmes (SAPs) have accelerated alongside interest in using SAPs to improve health and nutrition outcomes. However, evidence of how design features within and across programme types influence the effectiveness of SAPs for improving diet and nutrition outcomes among women and children is limited. To address this, we reviewed evaluations of cash, in‐kind and voucher programmes conducted between 2010 and 2020 among women and children, and examined associations between design features (targeting, including household and individual transfers, fortified foods and behaviour change communication) and positive impacts on diet (diet diversity, micronutrient intake) and nutrition (anthropometric indicators, haemoglobin, anaemia) outcomes. Our review has several key findings. First, SAPs improve dietary diversity and intake of micronutrient‐rich foods among women and children, as well as improve several nutrition outcomes. Second, SAPs were more likely to impact diet and nutrition outcomes among women compared with children (23/45 [51%] vs. 52/144 [36%] of outcomes measured).
