Nutritional Characterization of Traditional Foods Based on Millet, Sorghum and Cowpea from the North-Central Region of Burkina Faso

The food and nutrition situation in Burkina Faso, like most developing countries in sub-Saharan Africa, is marked by growing food vulnerability. The majority of local dishes are being abandoned in favor of a minority of imported cereal dishes and other ultra-processed foods. This minority of cereal foods is blamed for stunted growth in children, while ultra-processed foods are linked to chronic diseases such as hypertension, certain types of diabetes and cancer. Knowledge of the nutritional value of local foods is needed to determine their nutritional quality. The aim of this study was to determine the nutritional values of local dishes based on millet, sorghum and cowpea in the Centre-North region. The methodology consisted of making an inventory of millet-, sorghum- and cowpea-based dishes using focus groups made up of women and men from three age groups comprising young people, adults and the elderly in the communes of Lebda and Boussouma. The dishes were reproduced, and standard biochemical methods were used for nutritional characterization. A total of 34 dishes were inventoried, including 16 millet/sorghum-based dishes, 8 cowpea-based dishes and 10 dishes composed of millet/sorghum and cowpea or leaves. The mean protein, carbohydrate, ash and iron contents per 100 g DM of the three types of dishes were significantly different (p ≤ 0.05), ranging respectively from 13.61 to 22.63 g, 70.76 to 80.88 g, 1.87 to 5.96 g and 7.67 to 12.06 mg. Those for lipid, energy and zinc were not significantly different, ranging from 5.51 to 6.56 g, from 427 to 433 Kcal and from 2.98 to 3.32 mg respectively. Cowpea-based and mixed dishes cover the nutritional requirements for protein, carbohydrates, iron, zinc and energy recommended for children and adults. The consumption of mixed dishes and cowpea-based dishes could be promoted by nutritional policy to reduce stunting and recommended to obese, hypertensive and diabetic people as part of their diet.

Factors Contributing to Contamination of Street Foods in Bamako, Mali

The World Health Organization states that foodborne diseases are a worldwide public health issue. Although street foods can provide nutritious and affordable ready-to-eat meals for city dwellers, their health risks can outweigh the benefits. A cross-sectional study was conducted in the Bamako district, focusing on street food vendors near schools, universities, extensive markets, administrative centers, and major roads. We aimed to sample fifty (50) sellers per municipality, making 300 sellers for the Bamako district. We developed a survey sheet to collect data, and six teams rotated between the municipalities each month. Before starting the collection, the teams were provided administrative papers approved by the municipal authority. The survey revealed three types of sales sites: fixed (65%), semi-fixed (30%), and mobile (4.40%). The proportion of sellers was 26.8%, 23.2%, 19.7%, and 4.2% in municipalities III, IV, and I. In municipalities I, II, III, IV, and VI, respectively, 92%, 95.70%, 93%, 87.2%, and 100% of the sellers were female. The age distribution of sellers was 65.63%, 46.81%, 40.82%, 38.30%, 36.17%, 36%, and 32% in the 25-34 and 35 - 44 age groups. Illiteracy rates were 59.20%, 61.70%, 55.30%, 75%, and 56% in municipalities I, II, III, IV, and VI, respectively. The study identified two categories of sellers: 48.3% in type 1 and 51.7% in type 2. The first category comprised 154 sellers, and the second 165 sellers. The survey found that 66.00%, 56.00%, 48.90%, 44.90%, 38.30%, and 34.40% of municipal V, VI, III, I, II, and IV sales sites were open-air. In municipality I, 63.30% of the sites were under hangars, while in municipalities II and IV, the corresponding percentages were 51.10% and 59.40%, respectively. Moreover, 46.00%, 31.90%, 31.30%, 30.60%, and 27.70% of the sites in municipalities VI, II, IV, I, and III were located next to gutters. In conclusion, this study identified several factors that could compromise the quality of street foods sold in the six municipalities of Bamako.

Giving Food a Fiber Boost: Adding High Beta-Glucan Ingredient from Barley to Everyday Foods

Lack of dietary fiber contributes to many health issues, particularly chronic vascular diseases. Mixed linkage β-1.3 - 1.4 beta-glucan (beta-glucan, in this paper) is a confirmed beneficial ingredient for the human diet through reduction of cholesterol and the glycemic index. Barley contains the highest beta-glucan content of all the grains, and in this study, a percentage of flour from two high beta glucan lines was, each, added to an array of wheat-based food products to measure how it impacted total dietary fiber. Results showed that beta-glucan content was higher in all the products containing the added high beta-glucan flour, along with increased total dietary fiber content. Protein content in the food products is also increased with the higher protein in the barley flours added. Beta-glucan content in the barley-added products increased to 1.2% - 4.0% versus 0.2% - 0.5% in the pure wheat products, while the dietary fibers increased to 3.5% - 24.4% versus 2.1% - 9.1% in pure wheat product controls. This research provided experimental evidence that using a high beta-glucan barley ingredient in food can increase dietary fiber to benefit health.

Food intolerance and the few-foods(or oligoantigenic)diet in children with attention-deficit hyperactivity disorder

The hypothesis that some children with attention-deficit hyperactivity disorder(ADHD)may show sensitivity or allergic reactions to various food items has led to the development of the the few-foods(or oligoantigenic)diet.The rationale of the diet is to eliminate certain foods from the diet in order to exclude potential allergens contained either naturally in food or in artificial ingredients with allergenic properties.The oligoantigenic diet attempts to identify individual foods to which a person might be sensitive.First,ADHD symptoms are monitored while multiple foods are excluded from the diet.Subsequently,if symptoms remit,foods are re-introduced,while observing the individual for the return of symptoms.An advantage of the oligoantigenic diet is that it can be tailored to the individual.A growing body of evidence suggests that behavioral symptoms of subgroups of children with ADHD may benefit from the elimination of certain foods.The effect sizes of an oligoantigenic diet regarding improvement of ADHD symptoms have been found to be medium to large.Available evidence suggests that the investigation of the role of food hypersensitivities in ADHD is a promising avenue worthy of further exploration.Further large-scale,randomized controlled studies including assessment of long-term outcome are therefore warranted.

Comprehensive analysis of advanced glycation end-products in commonly consumed foods:presenting a database for dietary AGEs and associated exposure assessment

Advanced glycation end-products(AGEs)are a group of heterogeneous compounds formed in heatprocessed foods and are proven to be detrimental to human health.Currently,there is no comprehensive database for AGEs in foods that covers the entire range of food categories,which limits the accurate risk assessment of dietary AGEs in human diseases.In this study,we first established an isotope dilution UHPLCQq Q-MS/MS-based method for simultaneous quantification of 10 major AGEs in foods.The contents of these AGEs were detected in 334 foods covering all main groups consumed in Western and Chinese populations.Nε-Carboxymethyllysine,methylglyoxal-derived hydroimidazolone isomers,and glyoxal-derived hydroimidazolone-1 are predominant AGEs found in most foodstuffs.Total amounts of AGEs were high in processed nuts,bakery products,and certain types of cereals and meats(>150 mg/kg),while low in dairy products,vegetables,fruits,and beverages(<40 mg/kg).Assessment of estimated daily intake implied that the contribution of food groups to daily AGE intake varied a lot under different eating patterns,and selection of high-AGE foods leads to up to a 2.7-fold higher intake of AGEs through daily meals.The presented AGE database allows accurate assessment of dietary exposure to these glycotoxins to explore their physiological impacts on human health.

Haba and Huitlacoche,Nutritious Foods of Little Consumption

Haba and Huitlacoche are foods of little consumption worldwide.Both provide nutrients to the human body due to the fiber,antioxidants,vitamins and essential amino acids they contain.The broad bean can be grown alone or intercropped with corn and pumpkin.Huitlacoche is a fungus that affects corn,however in Mexico it has been used as food since the times of the Aztec culture.

The hypoglycemic potential of phenolics from functional foods and their mechanisms

Long-term postprandial hyperglycemia is a primary risk factor for developing chronic metabolic diseases such as obesity,type 2 diabetes,and cardiovascular disease.Chronic hyperglycemia induces the glycation of proteins,oxidative stress,inflammation and increases plasma insulin and lipid concentrations.Insulin resistance is the primary cause of postprandial excursions of blood glucose and lipids.Hyperglycemia can be treated by lowering dietary carbohydrates intake,digestion,and absorption.Various functional foods improve glucose metabolism by increasing insulin sensitivity and inhibitingα-glucosidase in the small intestine.Natural phytochemicals,especially active phenolics are good antioxidants and show anti-inflammatory action and regulate blood glucose.This review aimed to report on hypoglycemic properties of active phenolics from functional foods and their proposed anti-diabetic mechanisms.Nevertheless,further clinical trials are required to confirm the bioavailability,safety,and efficacy of phenolics,especially the dosage and duration of treatment,to avoid adverse effects and give better dietary recommendations.

Gut microbiota axis:potential target of phytochemicals from plant-based foods

Food-microbiota-host interactions provide an overarching framework for understanding the function of the gut microbiota axis.Diet is a major modulator of gut microbiota.Plant-based foods are rich in phytochemicals;therefore,it is essential to assess such foods and elucidate the mechanisms underlying their action.In this review,we summarize the role of gut microbiota in the communication between the gut and the brain,liver,lung,kidney,and joints,as well as the role of the gut microbiota axis in diseases involving these organs.In addition,we assess the effects of phytochemicals from plant-based foods on the gut microbiota axis via different pathways.

Roles of fermented plant-,dairy-and meat-based foods in the modulation of allergic responses

This review attempts to delineate the effects and roles of fermented foods on allergic responses(AR),specifically from milk,plant,and meat sources.Evidence for AR alleviation and aggravation were noted for many different fermented food groups.Positive outcomes on AR through fermented foods could be linked to microbial hydrolysis of food allergens,improvement in gut microbiota robustness,and modulation of the immune system that promotes a balance between T helper 1(Th1)and Th2 cells.Studies on plant-based,non-protein rich fermented foods tend to show more favourable results compared to those on meat-based or protein-rich group.The usage of specific and known starter cultures are helpful in alleviating AR,as in the case for many yogurt,Kefir or Dahi products.Sufficient fermentation time was also deemed important,exemplified in studies that showed inefficient AR reduction through consumption of fresh cheese.However,formation of new allergens through fermentation of certain meat-based foods,or by using specific fermenting microbes(e.g.Penicillium sp.),is possible.Thus,combination of starter cultures and food substrates must be considered in preventing or eliminating AR from intake of these foods.This review may aid consumers to make informed decision during the consumption of fermented food.

Determination of Veterinary Drug Residues in Animal-derived Foods by Liquid Chromatography-Mass Spectrometry

[Objectives]This study was conducted to establish a rapid and effective method for simultaneous extraction of 54 kinds of veterinary drug residues in animal-derived food, including sulfonamides, quinolones, tetracyclines, malachite greens, penicillins, nitroimidazoles, tranquilizers and macrolides, by HPLC-MS. [Methods] The samples were extracted with 80% acetonitrile water(containing 0.1% formic acid), combined with QuEChERS extraction technology and C18 and PSA purification, analyzed by high performance liquid chromatography-mass spectrometry, and quantified by external standard method. The target substances were analyzed on ZORBAX Eclipse C18 chromatographic column using 0.2% formic acid water and 0.2% methanol as mobile phases. The gradient elution mode was used for chromatographic separation and multiple reaction detection. [Results] In the linear range of 0.5-50.0 ng/ml, the linear relationship of the 54 kinds of veterinary drug residues was good, with correlation coefficients(r~2) greater than 0.995, and the detection limits ranged from 0.30 to 1.00 μg/kg. The results showed that the recovery ranged from 75.4% to 118.2% when different matrixes were added for recovery. [Conclusions] This method is simple, efficient, accurate, stable, and highly operable. It is applicable to simultaneous batch screening of veterinary drug residues in animal-derived food, and has high practical application value.

The impact of demographic dynamics on food consumption and its environmental outcomes:Evidence from China

With increasing population and changing demographics,food consumption has experienced a significant transition in quantity and quality.However,a dearth of knowledge remains regarding its environmental impacts and how it responds to demographic dynamics,particularly in emerging economies like China.Using the two-stage Quadratic Almost Demand System(QUAIDS)model,this study empirically examines the impact of demographic dynamics on food consumption and its environmental outcomes based on the provincial data from 2000 to 2020 in China.Under various scenarios,according to changes in demographics,we extend our analysis to project the long-term trend of food consumption and its environmental impacts,including greenhouse gas(GHG)emissions,water footprint(WF),and land appropriation(LA).The results reveal that an increase in the proportion of senior people significantly decreases the consumption of grain and livestock meat and increases the consumption of poultry,egg,and aquatic products,particularly for urban residents.Moreover,an increase in the proportion of males in the population leads to higher consumption of poultry and aquatic products.Correspondingly,in the current scenario of an increased aging population and sex ratio,it is anticipated that GHG emissions,WF,and LA are likely to decrease by 1.37,2.52,and 3.56%,respectively.More importantly,in the scenario adhering to the standards of nutritional intake according to the Dietary Guidelines for Chinese Residents in 2022,GHG emissions,WF,and LA in urban areas would increase by 12.78,20.94,and 18.32%,respectively.Our findings suggest that changing demographics should be considered when designing policies to mitigate the diet-environment-health trilemma and achieve sustainable food consumption.

Profile of the Functional Categories of Food Additives in Industrial Foods Marketed in Senegal

Food additives, whether natural or artificial substances, are widely used around the world to improve the sensory quality of products, extend their shelf life and make them more competitive. However, the abusive and uncontrolled consumption of food additives is the cause of numerous illnesses and diseases such as poisoning, allergies, diabetes and numerous cancers. So, in addition to setting up control and regulatory bodies, it is becoming essential to keep a constant watch on the presence of food additives on the market. The aim of this study is to highlight the main categories of food additives in food products frequently sold on the Senegalese market. The methodology of the study is based on the identification of food additives from the information given on the labels of food packaging. Information was collected in markets in two (2) major regions of Senegal: Dakar and Saint-Louis. The results of our study show the presence of 153 food additives on the labels of 514 samples collected. Moreover, the frequency and diversity of additives depended on the food category. On the other hand, beyond their important technological and functional roles, some additives such as aspartame and monosodium glutamate have been implicated in pathologies, and others, such as titanium dioxide, are the subject of much controversy and even withdrawal in certain legislations for their impacts deemed potentially negative on consumer health.

Understanding Saudi Public’s Awareness, Perception, and Attitudes towards Genetically Modified Foods

Introduction: Recent technological developments have enabled many scientists to produce a wide variety of foods that meet consumers’ desires for diversity and quality. Genetically modified (GM) foods have long been a controversial topic, and consumer reliance on these foods depends on their trust in biotechnology institutions due to their lack of knowledge about the risks and benefits. This study aimed to assess the awareness, attitude, and perception of GM foods among the Saudi population, as well as to identify the association between age, gender, and education level in the studied population and their awareness level towards genetically modified foods. Method: Data was collected using a structured, pretested questionnaire drawn from previous studies, after obtaining written consent. The questionnaire included three sections focusing on personal data, general knowledge of GM foods, and perception, attitudes, and beliefs towards GM foods. Our study included 500 responses. Results: The majority of the participants were female, located in the central region, and had a university education. Most participants provided a correct definition of GM foods and indicated that they had heard about them, but were unsure if they had eaten these foods in the past. Their knowledge of these foods was good. Regarding opinions and attitudes towards these foods, the majority of participants were neutral. They approved of using GM foods because it produces more food, tastes better, and can be stored for a long time. In conclusion, the study highlights the urgent necessity to raise awareness and knowledge regarding genetically modified foods among the Saudi population. It emphasizes the importance of educating consumers about the potential advantages and risks associated with consuming such foods, enabling them to make informed decisions. It is crucial to integrate awareness and education about genetically modified foods into the technological and agricultural advancements in Saudi Arabia.

Resilience effects for household food expenditure and dietary diversity in rural western China

A more resilient livelihood is increasingly recognized as an efficient way to improve vulnerable households’food security and optimize their dietary decisions.This study quantifies rural household resilience in western China,identifies the three pillars(absorptive capacity,adaptive capacity,and transformative capacity)contribution to resilience,and then establishes the estimated Resilience Capacity Index(RCI)linked with food security and dietary diversity supported by the multiple indicator multiple cause(MIMIC)model.Results show that,despite geographical heterogeneity,the RCI consistently increased from 2015 to 2021.Households with a higher RCI inheriting better capacity to deal with risk and shocks are significantly and positively correlated with increasing food expenditure and diversifying food choices.It can be because resilient households will allocate more money to food expenditure instead of saving for livelihood uncertainty.Thus,policymakers can provide more incentives for rural households to adopt more dynamic and effective risk management strategies.This,in turn,could yield positive spillover effects by preventing human capital loss associated with dietary-related chronic diseases and mortality.

Natural and modified food hydrocolloids as gluten replacement in baked foods:Functional benefits

Gluten,the protein responsible for the superior viscoelastic properties of refined wheat flour dough over glutenfree cereals,causes celiac disease in people susceptible to gluten-allergy.Moreover,the sustainability of using wheat flour in baked foods is threatened by its high cost,especially in countries that depend on imported wheat for their bakery industry.Research has shown that hydrocolloids serve as gluten replacements in baked foods,in response to these challenges.Food hydrocolloids are a class of high-molecular weight polysaccharides and proteins,which serve as functional ingredients in the food industry that modify the foods’rheological and textural properties.They function as stabilizers,viscosity modifiers,gelling agents,water binders,fibres,and inhibitors of ice crystal in foods.Further,food hydrocolloids have also been reported to possess health-promoting properties,such as lowering of postprandial blood glucose and plasma cholesterol concentrations,colon cancer prevention,and modulation of intestinal transit and satiety.They are obtained from plants,animals or microorganisms,and can be used in their natural or modified forms.The aim of this paper is to review the functional benefits of natural and modified hydrocolloids as gluten replacements in baked foods,emphasizing their physicochemical,nutraceutical,and sensorial importance.The application effects of food hydrocolloids as gluten substitutes in gluten-free baked products’quality were discussed.Also,some practical approaches to improve the quality of gluten-free baked products,in response to an increasing consumers’demand and the rising cost of refined wheat flour were highlighted.

Potential Probiotic Tiger Nut-Cashew Nut-Milk Production by Fermentation with Two Lactic Bacteria Isolated from Ivorian Staple Foods

Probiotification of plant milk can improve its sensory and health-promoting properties. As traditional fermented foods where lactic acid bacteria (LAB) are present have been associated with beneficial effects on human health, the beneficial effects of two LAB recently isolated from two current Ivorian staple foods (a pepper and a traditional beer) were screened. These two strains LAC 1 (Lactobacillus plantarum) and LAC 2 (Pediococcus acidilactici) which presented probiotic, exopolysaccharides, inflammatory and anti-oxidant activities, were used to ferment a composite plant milk of tiger-nut and cashew (80/20) compared to two starters of a commercial yogourt. The obtained plant milks SCT 2 and SCT 3 with a significant increase in their antioxidant and/or anti-inflammatory activities and lactic bacteria contents were more preferred by consumers than SCT 1 obtained by fermentation of the commercial yogourt starters. The mixing of LAC 1 and LAC 2 was not beneficial. SCT 2 (with an anti-inflammatory activity of 31.38% and an anti-oxidant activity of 17.30%) and SCT 3 (with an anti-oxidant activity of 22.28) could be further tested in animal models to verify their nutrition-health claims.

Repositioning fertilizer manufacturing subsidies for improving food security and reducing greenhouse gas emissions in China

China removed fertilizer manufacturing subsidies from 2015 to 2018 to bolster market-oriented reforms and foster environmentally sustainable practices.However,the impact of this policy reform on food security and the environment remains inadequately evaluated.Moreover,although green and low-carbon technologies offer environmental advantages,their widespread adoption is hindered by prohibitively high costs.This study analyzes the impact of removing fertilizer manufacturing subsidies and explores the potential feasibility of redirecting fertilizer manufacturing subsidies to invest in the diffusion of these technologies.Utilizing the China Agricultural University Agri-food Systems model,we analyzed the potential for achieving mutually beneficial outcomes regarding food security and environmental sustainability.The findings indicate that removing fertilizer manufacturing subsidies has reduced greenhouse gas(GHG)emissions from agricultural activities by 3.88 million metric tons,with minimal impact on food production.Redirecting fertilizer manufacturing subsidies to invest in green and low-carbon technologies,including slow and controlled-release fertilizer,organic-inorganic compound fertilizers,and machine deep placement of fertilizer,emerges as a strategy to concurrently curtail GHG emissions,ensure food security,and secure robust economic returns.Finally,we propose a comprehensive set of government interventions,including subsidies,field guidance,and improved extension systems,to promote the widespread adoption of these technologies.

Women’s empowerment and food consumption:Evidence from female-headed households in Tanzania

Despite the growing recognition of women’s increasing role in the household and corresponding empowerment programs in sub-Saharan Africa,intensive research on the relationship between women’s influence and household food consumption is minimal.Using the most recent(2017-2018)national household survey data from Tanzania,this study examined the influence of women’s empowerment on household food consumption.First,we compared the monthly consumption of eight food categories between female-headed households(FHHs)and male-headed households(MHHs)using both descriptive statistics and the propensity score matching(PSM)method.Furthermore,we adopted the two-stage Linear Expenditure System and Almost Ideal Demand System model(LES-AIDS)to estimate income and price elasticities for the two household types.The results show that FHHs consume bread and cereals,fish,oils and fats,vegetables,and confectionery(sugar,jam,honey,chocolate,etc.)more than MHHs.Moreover,FHHs have a significantly higher income elasticity of demand for all food groups than MHHs.They are also more price elastic than MHHs in meat,fish,oils,fats,sugar,jam,honey,chocolate,etc.

Immunoglobulin G-mediated food intolerance and metabolic syndrome influence the occurrence of reflux esophagitis in Helicobacter pylori-infected patients

BACKGROUND Reflux esophagitis has an increasing prevalence and complex and diverse symptoms.Identifying its risk factors is crucial to understanding the etiology,prevention,and management of the disease.The occurrence of reflux esophagitis may be associated with food reactions,Helicobacter pylori(H.pylori)infection,and metabolic syndromes.AIM To investigate the risk factors for reflux esophagitis and analyze the effects of immunoglobulin(Ig)G-mediated food intolerance,H.pylori infection,and metabolic syndrome on reflux esophagitis.METHODS Outpatients attending the Second Medical Center of the PLA General Hospital between 2017 and 2021 were retrospectively enrolled.The patients’basic information,test results,gastroscopy results,H.pylori test results,and IgG-mediated food intolerance results were collected.Multivariate logistic regression analysis was used to analyze risk factors for reflux esophagitis.Statistical mediation analysis was used to evaluate the effects of IgG-mediated food intolerance and metabolic syndrome on H.pylori infection affecting reflux esophagitis.RESULTS A total of 7954 outpatients were included;the prevalence of reflux esophagitis,IgG-mediated food intolerance,H.pylori infection,and metabolic syndrome were 20.84%,61.77%,35.91%,and 60.15%,respectively.Multivariate analysis showed that the independent risk factors for reflux esophagitis included IgG-mediated food intolerance(OR=1.688,95%CI:1.497-1.903,P<0.00001)and metabolic syndrome(OR=1.165,95%CI:1.030-1.317,P=0.01484),and the independent protective factor for reflux esophagitis was H.pylori infection(OR=0.400,95%CI:0.351-0.456,P<0.00001).IgG-mediated food intolerance had a partially positive mediating effect on H.pylori infection as it was associated with reduced occurrence of reflux esophagitis(P=0.0200).Metabolic syndrome had a partially negative mediating effect on H.pylori infection and reduced the occurrence of reflux esophagitis(P=0.0220).CONCLUSION Patients with IgG-mediated food intolerance and metabolic syndrome were at higher risk of developing reflux esophagitis,while patients with H.pylori infection were at lower risk.IgG-mediated food intolerance reduced the risk of reflux esophagitis pathogenesis in patients with H.pylori infection;however,metabolic syndrome increased the risk of patients with H.pylori infection developing reflux esophagitis.
