Indigenous food ingredients for complementary food formulations to combat infant malnutrition in Benin : a review

This paper reviews indigenous Beninese food resources as potential ingredients for complementary infant foods with the aim to develop affordable formulations for low-income households in each agro-ecological zone of the country. Potential ingredients were selected on their documented nutritional value. The selected foods encompass 347 food resources, namely 297 plant products from home gardens or collected from natural vegetation and 50 animals, either domesticated or from the wild. The compiled data reveal that the distribution of the available food resources was unbalanced between agro-ecological zones. Only a few animal ingredients are obtainable in northern Benin. Most resources are seasonal, but their availability may be extended. A high variation was observed in energy and nutrient contents. Antinutritional factors were identified in some resources, but processing techniques were reported to reduce their presence in meals. In general, ingredients from local tree foods (Adansonia digitata, Parkia biglobosa) were adequate as sources of nutrients for complementary infant foods. Based on this review, local foods for the development of complementary food formulas for Beninese infants and children may be selected for each agro-ecological zone. The approach used is exemplary for other sub-Saharan African countries in need of complementary infant foods

Cohort profile: effect of malaria in early pregnancy on fetal growth in Benin (RECIPAL preconceptional cohort).

PURPOSE: REtard de Croissance Intra-uterin et PALudisme (RECIPAL) is an original preconceptional cohort designed to assess the consequences of malaria during the first trimester of pregnancy, which is a poorly investigated period in Africa and during which malaria may be detrimental to the fetus. PARTICIPANTS: For this purpose, a total of 1214 women of reproductive age living in Sô-Ava and Akassato districts (south Benin) were followed up monthly from June 2014 to December 2016 until 411 of them became pregnant. A large range of health determinants was collected both before and during pregnancy from the first weeks of gestation to delivery. Five Doppler ultrasound scans were performed for early dating of the pregnancy and longitudinal fetal growth assessment. FINDINGS TO DATE: Pregnant women were identified at a mean of 6.9 weeks of gestation (wg). Preliminary results confirmed the high prevalence of malaria in the first trimester of pregnancy, with more than 25.4% of women presenting at least one microscopic malarial infection during this period. Most infections occurred before six wg. The prevalence of low birth weight, small birth weight for gestational age (according to INTERGROWTH-21st charts) and preterm birth was 9.3%, 18.3% and 12.6%, respectively. FUTURE PLANS: REtard de Croissance Intra-uterin et PALudisme (RECIPAL) represents at this time a unique resource that will provide information on multiple infectious (including malaria), biological, nutritional and environmental determinants in relation to health outcomes in women of reproductive age, pregnant women and their newborns. It will contribute to better define future recommendations for the prevention of malaria in early pregnancy and maternal malnutrition in Africa. It confirms that it is possible to constitute a preconceptional pregnancy cohort in Africa and provides valuable information for researchers starting cohorts in the future

Food Groups Associated with a Composite Measure of Probability of Adequate Intake of 11 Micronutrients in the Diets of Women in Urban Mali

The prevalence of micronutrient deficiency is high among women of reproductive age living in urban Mali. Despite this, there are little data on the dietary intake of micronutrients among women of reproductive age in Mali. This research tested the relationship between the quantity of intake of 21 possible food groups and estimated usual micronutrient (folate, vitamin B-12, calcium, riboflavin, niacin, vitamin A, iron, thiamin, vitamin B-6, vitamin C, and zinc) intakes and a composite measure of adequacy of 11 micronutrients [mean probability of adequacy (MPA)] based on the individual probability of adequacy (PA) for the 11 micronutrients. Food group and micronutrient intakes were calculated from 24-h recall data in an urban sample of Malian women. PA was lowest for folate, vitamin B-12, calcium, and riboflavin. The overall MPA for the composite measure of 11 micronutrients was 0.47 +/- 0.18. Grams of intake from the nuts/seeds, milk/yogurt, vitamin A-rich dark green leafy vegetables (DGLV), and vitamin C-rich vegetables food groups were correlated (Spearman's rho = 0.20-0.36; P 0.5, respectively. These findings can be used to further the development of indicators of dietary diversity and to improve micronutrient intakes of women of reproductive age. J. Nutr. 140: 2070S-2078S, 2010

Impact of Moringa oleifera Leaf Flour supplement on Weight Gain in Moderately Acutely Malnourished Children in Benin

In developing countries, malnutrition represents a public health problem, which affects many children under five, during their complementary feeding period. One way to overcome this problem is through the supplementation of complementary flours with locally available food resources, such as Moringa oleifera leaf (MOL). An experimental study was conducted from June through November 2019 in the southern-Benin, with moderately acutely malnourished (MAM) children, using a porridge made of a mixture of corn, malted sorghum, soybean, peanut, milk, and moringa leaf powder. A total of 150 MAM children aged 12-59 months were recruited and divided into two groups, an intervention group (48) and a control group (75). The intervention group received the test food, a porridge made of maize flour supplemented with Moringa oleifera leaf flour (MOL-flour), at least 5 times/week for 6 months. The control group, whose mothers received nutritional education sessions on food diversification as well as the different ways of preparing MOL meals. Sensory evaluation, anthropometric and dietary diversity data were collected. Z-scores Weight/Height, Weight/Age et Height/Age were determined before and right after the intervention. Results showed that 70% of the children and more than 75% of the mothers assessed the porridge as palatable. A significant average weight gain of 1.720 g (p < 0.005) was observed in the intervention group at the end of the experimentation, with a reduction of the prevalence of underweight by 1,33% (p > 0.05), and the number of acute Malnutrition children by 10,42% (p < 0.005)

Factors Explaining Adolescent Girls’ Eating Habits in Urban Benin: A Qualitative Study

Adolescence is a period between childhood and adulthood with eating habits often against the nutritional needs of adolescents. The present study used a socio-ecological approach to investigate personal and environmental factors influencing the eating habits of 15- to 19-years old Beninese urban schoolgirls. Eleven focus groups (n = 77) and seven individual interviews were conducted with adolescent girls attending school in Cotonou, Benin. Focus groups were as homogeneous as possible regarding age group and school character. Transcripts were analyzed using an inductive-deductive thematic method using the socio-ecological model. Taste preference for sweet foods, insufficient dietary knowledge and low personal income were factors explaining unhealthy food choices, while higher self-efficacy and healthy outcome expectations mainly characterized their healthy eating habits at the intrapersonal level. Family influence was beneficial for healthy eating while friends’ pressure led to an unhealthy diet at the interpersonal level. At the organizational level, adolescents reported unhealthy school food environments and urban areas increased their unhealthy eating habits. It appears that one factor alone is not enough to influence adolescent girls’ eating habits. Therefore, this study presents the need of elaborating interventions in a school context to improve eating habits in adolescents focusing on different factors in Beninese adolescent schoolgirls

Perception of secondary school adolescent girls on their own diet and health status in urban Benin

From childhood to adulthood, adolescence phase transition, implies many lifestyle changes. This study aims to investigate the perception of adolescent girls of their own diet and health status. A cross-sectional study, using a structured face-to-face administered questionnaire, were carried out in 395 adolescent girls 15 - 19 years old in secondary schools in Cotonou, in Benin. Chi 2 and Wilcoxon - Mann Whitney tests were performed to appreciate the variables associations. Logistic regression was executed to appraise the effect of self-perception on dietary practices. The average age of the participants was 16.7 ± 1.26 years. The prevalence of self-reported anaemia, diet quality and overweight/obesity was 18.23%; 57.72% and 9.87% respectively. Considering school character, more adolescents in private schools perceived themselves as being “overweight/obese” (22.8%) compared to their peers from public schools (0.4%). Self-perceived anaemia was related to dark green leafy vegetable and vitamin C-rich fruits consumption while self-perceived overweight/obesity decrease the consumption of meat and meat products. Adolescents who perceived their own diet as healthy reached the Minimum Dietary Diversity. The findings of this study highlight the importance of self-perception in adolescents eating habits and this should be considered in interventions improving their diet quality

Comparing intake estimations based on food composition data with chemical analysis in Malian women

Objective: Food composition databases are essential for estimating nutrient intakes in food consumption surveys. The present study aimed to evaluate the Mali food composition database (TACAM) for assessing intakes of energy and selected nutrients at population level. Design: Weighed food records and duplicate portions of all foods consumed during one day were collected. Intakes of energy, protein, fat, available carbohydrates, dietary fibre, Ca, Fe, Zn and vitamin A were assessed by: (i) estimating the nutrient intake from weighed food records based on an adjusted TACAM (a-TACAM); and (ii) chemical analysis of the duplicate portions. Agreement between the two methods was determined using the Wilcoxon signed-rank test and Bland–Altman plots. Setting: Bamako, Mali. Subjects: Apparently healthy non-pregnant, non-lactating women (n 36) aged 15–36 years. Results: Correlation coefficients between estimated and analysed values ranged from 0·38 to 0·61. At population level, mean estimated and analysed nutrient intakes differed significantly for carbohydrates (203·0 v. 243·5 g/d), Fe (9·9 v. 22·8 mg/d) and vitamin A (356 v. 246 µg retinol activity equivalents). At individual level, all estimated and analysed nutrient intakes differed significantly; the differences tended to increase with higher intakes. Conclusions: The a-TACAM is sufficiently acceptable for measuring average intakes of macronutrients, Ca and Zn at population level in low-intake populations, but not for carbohydrate, vitamin A and Fe intakes, and nutrient densities

Vegetable consumption in the food system of Benin : identifying drivers of consumer behaviour and entry point for interventions

Despite its health benefits, vegetable consumption in Sub-Saharan Africa is below recommended levels. This report is part of a larger project, aiming to pilot and scale innovative approaches within the food systems of Benin, Mali and Burkina Faso to improve consumption of safe vegetables. The aim of this report is to obtain insights into the vegetable consumption behaviour of urban consumers in Benin. For this purpose, a literature review was conducted. Results were reviewed and validated by relevant experts in the field of nutrition, health, and food safety in Benin. This was important as most relevant literature referred to the larger context of West Africa. This report describes the results for Benin and identifies potential entry points for enhancing the consumption of safe vegetables

Comparison of Micronutrient Intervention Strategies in Ghana and Benin to Cover Micronutrient Needs: Simulation of Bene-Fits and Risks in Women of Reproductive Age

Overlapping micronutrient interventions might increase the risk of excessive micronutrient intake, with potentially adverse health effects. To evaluate how strategies currently implemented in Benin and Ghana contribute to micronutrient intake in women of reproductive age (WRA), and to assess the risk for excess intakes, scenarios of basic rural and urban diets were built, and different on-going interventions were added. We estimated micronutrient intakes for all different scenarios. Four types of intervention were included in the scenarios: fortification, biofortification, supplementation and use of locally available nutrient-rich foods. Basic diets contributed poorly to daily micronutrient intake in WRA. Fortification of oil and salt were essential to reach daily requirements for vitamin A and iodine, while fortified flour contributed less. Biofortified products could make an important contribution to the coverage of vitamin A needs, while they were not sufficient to cover the needs of WRA. Iron and folic acid supplementation was a major contributor in the intake of iron and folate, but only in pregnant and lactating women. Risk of excess were found for three micronutrients (vitamin A, folic acid and niacin) in specific contexts, with excess only coming from voluntary fortified food, supplementation and the simultaneous overlap of several interventions. Better regulation and control of fortification and targeting of supplementation could avoid excess intakes
