ABSTRACT

Biofortification is an innovative agricultural approach aimed at reducing global micronutrient deficiencies, often referred to as "hidden hunger," by enhancing the nutritional quality of staple crops through breeding, genetic engineering, and agronomic practices. This strategy targets essential micronutrients such as iron, zinc, and provitamin A, particularly in regions where diets are predominantly based on nutrient-poor staple foods. Biofortified crops, such as vitamin A-enriched sweet potatoes and iron-rich beans, have demonstrated significant improvements in nutrient intake and health outcomes, including reduced anemia and enhanced child growth. Despite its promise, the adoption and widespread implementation of biofortified crops face multiple challenges, including technical constraints in breeding for nutrient stability and bioavailability, regulatory barriers for genetically modified varieties, and socio-cultural resistance due to consumer preferences and lack of awareness. Moreover, environmental factors, such as soil nutrient content and agro-ecosystem dynamics, can influence the success and sustainability of biofortification. Addressing these issues requires advancing research in nutrient bioavailability, developing more resilient crop varieties, and incorporating biofortification into broader food and nutrition policies. Scaling up biofortified crops will depend on effective community engagement, public-private partnerships, and integration into existing agricultural extension systems. Successful examples, such as the widespread adoption of orange-fleshed sweet potatoes in Sub-Saharan Africa, highlight the potential of biofortification to improve nutritional security and livelihoods when supported by targeted advocacy and policy initiatives. Thus, while challenges persist, biofortification remains a valuable, cost-effective solution to addressing micronutrient malnutrition and improving global food security, especially when implemented in tandem with other nutrition and health interventions.

ABSTRACT

This study aimed to enhance traditional cereal-based complementary foods in Nigeria by developing and evaluating a nutrient-dense blend of sweet potato, carrot, and crayfish. The objective was to address protein-energy malnutrition in low-resource settings by improving the nutritional profile of local complementary foods. Samples were analyzed in triplicate for proximate composition and selected micronutrients using AOAC standard techniques. Sensory evaluation was conducted using a 5-point hedonic scale with a panel of ten nursing mothers from the Department of Human Nutrition and Dietetics, Lead City University. Results showed that the blend contained 14.74�32% crude protein, 72.19�51% carbohydrates, and 0.97�02% fat. Micronutrient analysis revealed high levels of vitamin C (19.06�70 mg/100ml) and phosphorus (497.33�37 mg/100ml). Sensory evaluation indicated that the product was well-accepted, with mean scores of 4.2�6 for taste (slightly sweet), 4.0�7 for color (light brown), and 3.8�8 for flavor (mildly fishy). This novel blend significantly improves upon traditional cereal-based complementary foods by providing a more balanced nutrient profile that meets WHO/FAO recommendations. It offers a practical, locally-sourced solution to enhance infant nutrition in low-resource settings, potentially reducing the prevalence of protein-energy malnutrition. Further studies on its long-term effects on child growth and development are recommended.

ABSTRACT

Artocarpus heterophyllus (Jack fruit) and its seeds are nutritionally rich packed with proteins, carbohydrates, micronutrients, iron, dietary fibre, vitamin, resistant starch, and antioxidants. They lower the risk of heart diseases, controls blood sugar, promotes weight loss, help in managing stress levels, skin diseases, good eyesight, strengthens immunity of the body, and maintains gut health. The seed coat of jackfruit comprises a thin, waxy, parchment-like testa (husk) and a brown, membranous tegmen. Typically, the white outer membrane of jackfruit seeds is removed and discarded before consumption. In this study, we aimed to assess the nutritional and pharmacological properties of this unexplored slimy, white outer membrane. The methanolic extract of the seed coat membrane [Testa] was obtained using Soxhlet extraction and used for the analysis. Phytochemical analysis of the test sample revealed the presence of flavonoids, saponins, phenols, xanthoprotein, proteins, and phytosterols, with measurable amounts of phenols and proteins. The extract exhibited significant antioxidant activity with an IC50 value of 232 ?g/ml, using the DPPH method, and demonstrated cytotoxic properties. GC-MS analysis revealed the presence of several compounds with anticancer and antioxidant properties. The results imply that the extract has the potential to serve as an excellent source for antioxidant and anticancer drug in pharmaceutical medicines.

This is essential to implement preventive measures and treatment with vitamin A in order to avoid irreversible consequences.

ABSTRACT

This is an exhaustive narrative review on nutritional importance regarding periodontium health. Macronutrients have a significant impact on oral health. Highly refined carbohydrate intake has been linked to dental cavities and periodontal diseases. In contrast, complex carbohydrates in whole grains and vegetables promote periodontal health. Proteins are essential for host defenses and the synthesis of connective tissues, making them crucial for periodontal well-being. Vegetable proteins positively affect periodontal health. Dietary fats promote inflammation and increase the risk of periodontal disease. Omega-3 fatty acids are well-known for their anti-inflammatory properties and minimizing periodontal inflammation. Vitamins and minerals are essential in maintaining periodontal health. Vitamins A, D, and K are necessary for oral epithelial integrity, bone growth, and tissue maintenance. Ca2+ and Mg2+ deficiencies have been associated with severe periodontal diseases. Antioxidants like vitamin C can mitigate periodontal inflammation. Most dental practitioners acknowledge that a person’s nutritional status attenuates periodontal disorders. The severity of inflammation in the gums is indirectly impacted by the inherent resistance of the periodontal tissues to infection at a systemic level. Dental professionals should address local irritants through different procedures, promote daily plaque control at home, and offer nutritional counseling on improving overall periodontal health

ABSTRACT

Rice is a vital staple crop that serves as the primary source of calories for over half of the global population, particularly in Asia. Despite its importance, rice is inherently deficient in several essential micronutrients, and the nutritional value is further diminished through processing. This study examines the nutritional composition of fortified rice provided through the Public Distribution System (PDS) in KGBV hostels, emphasizing its potential to address nutritional deficiencies. The analysis focused on key parameters including moisture, ash, fat, crude fiber, protein, carbohydrates, energy, and iron content. Results revealed that fortified rice contains 11.8% moisture, 1.57% ash, 0.78% fat, and 31.05 mg of iron, crude fiber content was 0.3%, protein levels were 7.7%, carbohydrate content was 77.85g, and energy content was 349.22 kcal. These findings highlight the superior nutritional profile of fortified rice, particularly in terms of its ash, energy, and iron content, making it a highly beneficial option for addressing nutritional deficiencies and improving public health outcomes.

ABSTRACT

Though mostly ignored, micronutrients are most important. Reducing the negative effects of micronutrient shortages requires the use of effective techniques like vitamin supplements and dietary diversification. It is known that when agricultural yields are reduced because of inadequate soil micronutrient concentration, malnutrition may result. Deficits in soil micronutrients can result from a number of variables, such as the use of intensive cropping practices, micronutrient leaching, soil characteristics, and decreased use of farmyard waste. The availability of micronutrients in the soil is determined by a number of factors, including soil pH, and status of the soil organic matters. Numerous factors, including the structure of root hairs, the release of organic acids, sugar, and several root enzymes, as well as interactions between microorganisms and plants, affect how well plants absorb and use micronutrients. Numerous studies have been carried out to investigate the soil's micronutrient absorption and bioavailability. In order to improve crop utilisation of soil nutrients, the discussion also included an analysis of the relationships between plant functions and soil nutrients.

ABSTRACT

RESUMEN Perú generó 8.215.355 t de residuos sólidos municipales en el 2021; de este, 57,64 % corresponde a residuos orgánicos (RO) y 61,28 % son dispuestos en rellenos sanitarios con múltiples deficiencias de gestión, lo que exige buscar alternativas para tratar de manera segura los RO. Frente a esta situación, el compostaje permite la biotransformación, la reducción y la obtención de biofertilizantes, que se pueden aplicar como sustrato o enmienda. El objetivo de la investigación fue evaluar indicadores de procesamiento y calidad de compost derivado de residuos sólidos orgánicos urbanos, en Leoncio Prado, región Huánuco, Perú. Se evaluaron los tipos de residuos, basados en la normativa peruana para caracterización de residuos, los indicadores del proceso (temperatura y pH), la caracterización fisicoquímica y calidad en base a las normas internacionales. Los resultados muestran diferencia significativa para pH, nitrógeno, calcio, potasio, cobre y zinc; contrariamente, la materia orgánica, el % de cenizas, la conductividad eléctrica, el sodio y el fósforo no mostraron diferencias, siendo lo más destacado los altos niveles de pH, además, la calidad del compost es de "Clase B", según la norma chilena 2880. Los compost producidos son de calidad media y se recomienda su uso como sustrato o enmienda en la agricultura, previo tratamiento para corregir los altos niveles de pH.

ABSTRACT Peru generated 8,215,355 t of municipal solid waste in 2021, of which 57.64% corresponds to organic waste (OW) and 61.28% is disposed of in landfills with multiple management deficiencies, which makes it necessary to seek alternatives to safely treat OW. In view of this situation, composting allows biotransformation, reduction and obtaining biofertilizers that can be applied as a substrate or amendment. The objective of the research was to evaluate the processing indicators and quality of compost derived from urban organic solid waste in Leoncio Prado, Huánuco-Peru. Waste types were evaluated based on Peruvian regulations for waste characterization, process indicators (temperature and pH), physicochemical characterization and quality based on international standards. The results show significant differences for pH, nitrogen, calcium, potassium, copper and zinc; on the contrary, organic matter, % ash, electrical conductivity, sodium and phosphorus showed no differences, the most outstanding being the high pH levels, and the quality of the compost is "Class B" according to Chilean standard 2880. The compost produced is of medium quality and is recommended for use as a substrate or amendment in agriculture after treatment to correct the high pH levels.

ABSTRACT

Introduction. Altered serum zinc levels, lower and higher than values in healthy controls, have been observed in individuals affected by non-communicable chronic diseases. However, to date, studies describing potential determinants of zinc levels in general populations free of chronic diseases appear to be limited. Objective. To evaluate whether nutrient intake, biochemical and clinical measures, lifestyle, and family history of cardio-metabolic diseases are independently associated with zinc levels in apparently healthy individuals. Materials and methods. We evaluated 239 healthy subjects. Serum zinc was measured via flame atomic absorption spectrometry, and the remaining biochemical markers were assessed using enzymatic colorimetric methods. Standard techniques were employed to quantify waist circumference, height, and weight. Body fat was measured via bioimpedance, and blood pressure was measured using digital sphygmomanometers. We applied a survey to record the personal and family history of non-communicable chronic diseases, and nutrient intake was estimated using the 24-hour recall method. Results. Women had lower serum zinc levels than men. In multivariate analyzes, total fat intake (ß = -0.15; standard error = 0.03; p < 0.001), plasma log-triglycerides (ß = -10.18; standard error = 3.9; p = 0.010), and female gender (ß = -6.81; standard error = 3.3; p = 0.043) were significant predictors for serum zinc levels. Zinc intake was not significantly related to serum zinc in univariate and multivariate analyses. Conclusions. Variables related to cardiometabolic risk, such as plasma triglyceride levels and total fat intake, were associated with serum zinc levels in individuals without a diagnosis of chronic or infectious/inflammatory diseases. Further studies are required to confirm our findings and to evaluate possible biological mechanisms for these relationships.Keywords: Zinc; heart disease risk factors; triglycerides; micronutrients.

Introducción. Se han observado niveles séricos alterados de zinc, más altos o más bajos, en personas afectadas por enfermedades crónicas no transmisibles. Sin embargo, la información sobre determinantes de zinc sérico en poblaciones sin enfermedad crónica es muy limitada. Objetivo. Evaluar si la ingestión de nutrientes, las medidas bioquímicas y clínicas, el estilo de vida y los antecedentes familiares de las enfermedades cardiometabólicas están asociados de forma independiente con los niveles de zinc en individuos aparentemente sanos. Materiales y métodos. Se evaluaron 239 sujetos sanos. El zinc sérico se midió por espectrometría de absorción atómica de llama y el resto de los marcadores bioquímicos por métodos enzimáticos-colorimétricos. Se utilizaron técnicas estándar para medir la antropometría. Se aplicó una encuesta para registrar antecedentes personales y familiares, y se estimó el consumo de nutrientes por recordatorio de 24 horas. Resultados. Las mujeres tenían niveles séricos de zinc más bajos que los hombres. En los análisis multivariados, la ingestión total de grasas (ß = -0,15; error estándar = 0,03; p < 0,001), los triglicéridos plasmáticos (ß = -10,18; error estándar = 3,9; p = 0,010), y el sexo femenino (ß = -6,81; error estándar = 3.3; p = 0,043) fueron predictores significativos de los niveles séricos de zinc. La ingestión de zinc no estuvo significativamente relacionada con el zinc sérico en los análisis univariados y multivariados. Conclusiones. Las variables relacionadas con el riesgo cardiometabólico como los niveles de triglicéridos y la ingestión total de grasas se asociaron con los niveles de zinc en individuos sin diagnóstico de enfermedades crónicas o infecciosas-inflamatorias. Se requieren más estudios para confirmar estos hallazgos, así como la evaluación de los posibles mecanismos biológicos de estas relaciones.

Conclusiones: El consumo de calcio y vitamina D es deficiente en la población urbana costarricense y, presentó una relación inversa con el IMC(AU)

ntroduction: The presence of overweight and obesity increase the morbimortality of people in Latin America. Micronutrient deficiencies, such as calcium and vitamin D, are associated with an increased risk of obesity. Objective: To determine the relationship between vitamin D and calcium intake with risk factors for obesity in the Costa Rican urban population included in the ELANS Study. Materials and methods: For this analysis we used the 798 Costa Rican participants of the study (ELANS). The distribution of calcium and vitamin D intake was determined according to socioeconomic status, physical activity, and anthropometric measures. The Mann ­ Whitney and Kruskal-Wallis U tests were used, as well as linear and logistic regression models were performed. Results: Calcium and vitamin D intake was inadequate in more than 98% of the participants. Women, individuals with a lower socioeconomic level, low physical activity, younger age and those with excess weight and abdominal obesity presented lower consumptionofcalciumandvitamin D. Theconsumption of calcium and vitamin D was greater in the groups that have a lower BMI (p= 0.023 for calcium and p= 0.252 for vitamin D). The smaller the waist circumference, the greater the consumption of calcium and vitamin D (p= 0.002 for calcium and p= 0.008 for vitamin D). No association of the consumption of calcium and vitamin D was found in the regression models. Conclusions: Consumption of calcium and vitamin D is deficient in the Costa Rican urban population, and more prevalent among those with higher BMI. Arch Latinoam Nutr 2024(AU)

ABSTRACT

BACKGROUND:Osteonecrosis is a common refractory disease in clinical practice,and observational studies have suggested that micronutrients may have a prognostic role in osteonecrosis.However,the specific causal association between micronutrients and osteonecrosis is not known. OBJECTIVE:To explore the causal association between micronutrients and osteonecrosis by Mendelian randomization using summary data from a large population-based genome-wide association study(GWAS)for clinical diagnosis and treatment. METHODS:The required exposure and outcome data(calcium,magnesium,iron,vitamin E,carotenoids,retinol&osteonecrosis)were extracted from the IEU OpenGWAS database,GWAS catalog database,and FinnGen database.Data were analyzed by bidirectional Mendelian randomization with inverse-variance weighted as the primary study method,and weighted median method,simple mode method,weighted mode method,and MR-Egger regression to complement the results.The reliability of the data was then verified through sensitivity analyses. RESULTS AND CONCLUSION:(1)The results found a positive correlation between serum iron concentration and osteonecrosis,while no correlation was found for other micronutrients.There was no reverse causality in all the data.(2)The results of sensitivity analysis showed a robust causality.(3)By Mendelian randomization method,this study provided evidence of causality between serum iron concentration and osteonecrosis,and understanding the causality of micronutrient elements on osteonecrosis can help in the clinical diagnosis and treatment of osteonecrosis,which is of great clinical significance.

ABSTRACT

ABSTRACT Objective This study aimed to assessment the risk factors affecting development of hypothyroidism and to examine the selected dietary micronutrient intakes of primary hypothyroidism, subclinical hypothyroidism and euthyroid individuals comparing the healthy control group, and to evaluate the relationship between dietary micronutrient intakes and serum thyroid hormones. Additionally, this study planned to observe anxiety severities in different hypothyroidism groups. Methods This case-control study was carried out with 120 individuals: 60 in the patient group and 60 in the control group. The patient group was further subdivided into primary hypothyroidism, subclinical hypothyroidism, and euthyroid groups. A questionnaire and the Beck Anxiety Inventory were administered to all participants. 24-hour food consumption records, anthropometric measurements, biochemical parameters were taken. Results When serum vitamin D level increased by one unit (ng/mL), risk of disease decreased by 1%; and when age (year) increased by one unit, risk of disease increased by 5.1%. Dietary micronutrient intakes were similar in all groups. There were negative correlations between serum T4 levels and selenium intake in primary hypothyroidism group, and serum TSH levels and copper intake in subclinical hypothyroidism group, and serum TSH levels and iodine intake in control group. Beck Anxiety Inventory scores of patient groups were higher than control group. There was no statistically difference between primary, subclinical and euthyroid hypothyroidism groups in terms of anxiety scores. Conclusion Serum vitamin D level and age affected the risk of hypothyroidism. Micronutrient intake was associated with thyroid parameters. Anxiety was higher in hypothyroid patients, independent of thyroid hormone levels.

ABSTRACT

Vegetables are one of the main elements in terms of ensuring a person's food security and nutritional well-being. Integrated application of macronutrients coupled with adequate incorporation of micronutrients is one of the key factors for quality vegetable production. For ensuring maximum vegetable production with superior quality foliar nutrition is the better alternative in the era of climate change. Foliar application is the easiest and most effective way to administer micronutrients as compared to other methods. Trace elements such as iron (Fe), zinc (Zn), manganese (Mn), molybdenum (Mo), boron (B), chlorine (Cl), copper (Cu), and nickel (Ni) are essential for vegetable crops. The primary goal of this review article is to investigate the merits of micronutrients and the production potential of various vegetable crops through foliar nutrition. Additionally, this study aims to clarify the role of micronutrients in quality vegetable production. Several studies suggested that the exogenous application of micronutrients has a tremendous effect on overall growth and quality in a variety of crops. Many researchers have demonstrated that applications of Boron @250ppm significantly influenced the fresh weight of fruit, number of fruits per plant, number of seeds per plant, germination%, vigour index and root and shoot lengths of seedlings in sweet pepper. Various researchers also concluded that the application of Zn @1000 ppm + B @200 ppm + Mo @50 ppm provides a significant impact on head diameter, volume of head, chlorophyll a, chlorophyll b and chlorophyll total in cabbage.

ABSTRACT

The current study, named "effect of micronutrients and biofertilizer on yield parameters of coriander Coriandrum sativum (L.) cv. RCR-41," is planned to be carried out in the Research Field, Department of Horticulture, College of Agriculture, Gwalior, M.P., during Rabi 2020-21 and 2021-22. The experiment was designed in a Completely Randomized Block Design (CRBD) with two factors concepts i.e., Micronutrients (ZnSO4 (0.5%), FeSo4 (0.5%), CuSo4 (0.5%), Biofertilizers (Phosphorus Solubilizing Bacteria (PSB), Azotobacter, Potassium Solubilizing Bacteria (KSB) and replicated three times and included three replications. At the time of coriander seeding, treatments combinations including RDF doses of fertilisers and biofertilizers were used. The results showed that treatment M1 (ZnSO4 @ 0.5%) was the optimum micronutrient level treatment for coriander production. Treatment B2 (Azotobacter) was shown to be the optimal biofertilizer level for coriander production. The treatment combination M1B2 (ZnSO4 @ 0.5% x Azotobacter) was shown to be considerably better among all treatment combinations, yielding the highest coriander yield characteristics.

ABSTRACT

Soil fertility evaluation of barren land is the most basic decision-making tool for an effective sustainable plan for a particular area. Thus, the present study was carried out to evaluate the soil fertility status in session variation of the two blocks of Kanpur Dehat (Akabrpur and Maitha). The soil samples were randomly collected based on the variability of land at a depth of 0-15 cm, 15-30 cm, and 30-60 cm in 5-5 sites in the both blocks. A GPS device was used to identify the location of the soil sampling points. Soil samples were analyzed for texture, pH, OC, EC, N, P, K, S, Fe, Zn, Cu, Mn, and exchangeable cations status following standard analytic methods in the laboratory of Soil Science and Agricultural Chemistry, C.S.A. University of Agriculture and Technology, Kanpur, UP. The soil organic carbon ranged from 0.18 to 0.34% of both blocks. Available nitrogen ranged from 102.78 to 138.39 kg ha-1, available phosphorous ranged from 9.89 to 16.47 kg ha-1 and available potassium ranged from 230.65 to 276.38 kg ha-1 in the surface soil of Maitha, all of which showed a decrease in value with increase in depth. Exchangeable calcium ranged from 4.58 to 6.34 (cmol (p+) kg-1), exchangeable magnesium ranged from 2.20 to 4.40 (cmol (p+) kg-1), and the pH of the soil in both blocks was highly alkaline in nature, all of which varied significantly with site and depth. The results indicated that soils are not good for the cultivation of various crops. Farmers are required to maintain Soil Health Card which helps them to adopt suitable management practices and provide proper nutrition to soil.

ABSTRACT

Micronutrient deficiencies play a significant role in impacting the yield and quality of grapes in vineyards. To address the deficiencies, a field study was conducted during the summer, of 2022 by using foliar micronutrient mixtures in three different concentrations (0.5%, 1.0%, and 1.5%), with one spray during pre-fruit set stage and twice at pre-fruit set/berry growth stages. The study aimed to investigate the effects of foliar micronutrient application on the biochemical quality characteristics of the Muscat Hamburg grapevine cultivar. The results of the study showed that the application of micronutrients spray showed a beneficial impact on all the yield parameters, such as number of bunches per vine (ranging from 28 to 44), the yield per vine (varied from 5.56 to 6.55 kg per vine), with overall yield range between 20.7 to 24.2 t ha-1. The biochemical properties of the berries, including sugars (reducing, non-reducing, and total sugars), juice pH and content, TSS (Total Soluble Solids), Titrable acidity, and berry firmness, were found to be high in grapevines sprayed at 1.0% twice. Results showed that total sugars ranged from 15.2% to 10.7%, with a juice pH of 3.47 to 3.94, juice content of 83.5 to 95.5%, and TSS from 15.6 to 17.40º Brix. Regarding the Titrable acidity and firmness of the berries, the outcomes showed a range of 0.92% to 1.14% for acidity and 9.4 to 12.9 N for firmness. Findings from the study clearly showed that applying 1.0% micronutrients twice at fruit-set and berry stages increased yield and improved quality indices of Paneer grapes.
