The survey was conducted in seven provinces. Three approaches to data gathering were used: group interviews in which forms were filled out during interviews; individual interviews in which the interviewer asked one person about the survey-related tasks; and semi-structured group interviews. The survey data were analyzed and the results obtained made it possible to draw up four technological diagrams of almond products and three of almond processing into butter. The surveys showed that shea kernels were produced by boiling, pit fermented, and then smoked, or only smoked. In terms of butter making, the classic churning and roasting processes were used. These results revealed that the processes of butter making and processing are not uniform in all the units of producers. However, further studies are recommended, especially to determine the physico-chemical, sensory, and microbiological parameters of the butter from the productions to better appreciate their qualities.

Thus, introducing adequate complementary foods in the child's diet is essential for his development. Very few studies have looked at the compliance of local infant flours with compositional standards. The objective was to evaluate the macronutrient adequacy of local infant flours sold in Ouagadougou for the needs of children aged 6-23 months. Nutritional parameters were determined using reference methods. The modeling was performed using Excel 2016 software. Fats content ranged from 6.16g to 16.76g, proteins from 6.18g to 22.08g, carbohydrates from 63.4g to 70.96g, and energy values from 406.02 kcal/100g to 458.92 kcal/100g.

Pesticides are a potential health hazard for users and consumers and are a major constraint to the export and commercialization of mangoes. The objective of this study was to evaluate phytosanitary practices in orchards and pesticide residue levels in four varieties of fresh and dried mangoes (Amelie, Brooks, Kents and Lippens) produced in four localities in Burkina Faso in order to determine their health impact on consumers. Surveys on pesticide use and monitoring of phytosanitary practices were carried out among 16 orchard owners in the localities of Bobo-Dioulasso, Orodara, Toussiana and Banfora, a high mango production area. Also, a total of 120 samples, including 60 samples of fresh mangoes and dried 60 samples of dried mango were collected. A multi-residue method was developed to detect pesticide levels in the collected samples by gas chromatography with a micro-electron capture detector. The study revealed the use of unauthorized pesticides, often specifically for other crops, and a monitoring trapping network in the orchards against insects. 34 chemical pesticides were detected in 120 samples of all mango varieties collected. Pesticide residues were detected in 72% of the samples, and of the positive samples, 48.52% contained concentrations above the maximum residue limit permissibility. Organochlorine pesticide residues were present in fresh mangoes (60.5%) and a total of fifteen active compounds were detected in dried mangoes. The very poor management and use of pesticides found in these orchards could pose a threat to the productivity of natural ecosystems

In Burkina Faso, chronic kidney disease (CKD) is a major public health problem due to its increasing prevalence, severity and the high cost of treatment. Aim. The aim of this study was to describe nutritional status of subjects diagnosed with severe and moderate stages of chronic renal insufficiency, followed in nephrology consultation at the Yalgado Ouedraogo University Hospital Center (YO-UHC) of Ouagadougou. Methods. A descriptive cross-sectional study conducted over a period of eight months and included 75 patients in total. The socialdemographic parameters were determined on the basis of the patients' declaration and the use of their medical records. Biological parameters were collected from the results of laboratory examinations performed by each patient. The nutritional status of the patients was assessed by the anthropometric method. Finally, all patients were asked about their dietary habits and lifestyle using the 24-hour recall method. Results. Our results revealed a male predominance, out of the total number of patients included. The percentage of men and women was 54.70% and 45.30% respectively with a sex (male/female) ratio of 1.20. The average of Body Mass Index was 24.79 Kg/m 2. The percentage of overweight and obesity of women was 64.71% compared to 26.83% for men. The proportion of women with severe chronic kidney disease (58.82%) was twice as high as that of men (29.27%), (P<0.05). The average waist circumference of the subjects aged 30-39 years was significantly lower than that of the subjects aged 60-85 years. So, average hip circumference was 93.77 cm, with a significant difference according to sex (P<0.05). The prevalence of hyperglycaemia and diabetes increased with age. Hyperglycaemia in the 40-49 age group was increased significantly from 16.67% to 26.67% in the 70-85 age group (P<0.05). Diabetes in the 50-59 age group was 10% and doubled in the 70-85 age group (P<0.05). A percentage of 67.99% of the patients had a history of hypertension in either first-degree relatives or collaterals. The highest proportion was found in the hypertensive collaterals (37.33%; P=0.059). This study revealed a low level of physical activity among all patients. Only 38.67% of the patients practiced regular physical activity. There was no significant association between the level of physical activity and the stage of renal failure. Conclusion. Knowledge of nutritional status is a crucial part of better nutritional management of CKD patients. Finally, previous studies on the dietary habits of patients suffering from CKD will allow a better understanding of their nutritional status for a better management according to the stage of progression of the disease.

The objective of this review is to identify the most effective nutrition programs used in the prevention and management of child malnutrition in children under five years. Also, it is to suggest courses of action to improve interventions in the fight against malnutrition. The promotion of exclusive breastfeeding and food diversification improves the mothers' knowledge and contributes to prevention of malnutrition. Food supplementation increases the weight/height ratio of malnourished children. The two programs combined bring better results on mothers' feeding practices and children's anthropometric data. This review has highlighted the importance of food supplementation and nutritional education in the management and prevention of child malnutrition. In addition, the combination of several approaches to good dietary practices brings better results. Finally, primary prevention can protect children from the harmful consequences of malnutrition.

These oils come from various animal materials raw and vegetable products. Edible oils are prone to many contaminants. Contaminants can be found at all levels from oilseed production to conservation through refining processes and end up in oils. The contaminants origin may be of endogenous or exogenous. These are water, phosphorus, non-visible insoluble compounds, free fatty acids, residual hexane, benzo [a] pyrene, pesticides, dioxins, mycotoxins, mineral oils, cargo residues, minerals such as iron, copper, lead, gossypol, many primary and secondary oxidation products, etc. To eliminate or limit these compounds having a nuisance or toxicity for the consumer, it is allowed the refining of oils (chemical, physical or enzymatic). In addition, the regulatory limits of anti-nutritional factors in edible oils have been set in order to obtain quality oils and to guarantee the health of consumer living in developing country. This results in analytical methods developed for quantitative and qualitative evaluation of oils intended for human consumption. Contribution/Originality: This study on the contaminants of edible oils contributes to knowledge the sanitary consumption of these oils and their analytical methods. Previously, the contaminants in the oils did not experience infatuation. Our study focuses on pesticides, mycotoxins and gossypol which are anti-nutritional factors present in edible oils widely consumed.
