Copper (Cu) has a strong impact on the function of the immune system through several different pathways. These impacts include helping the function of monocytes, neutrophils, and macrophages, and enhancing Natural Killer cells’ activities. Cu also has a role in antimicrobial properties and inflammatory response. It is also important for IL-2 production and response, which is a component of adaptive immune cells. Additionally, Cu has multiple roles in both proliferation and differentiation of T cells and is involved in the production of antibodies. Cu deficiency can even lead to "increased viral virulence"1. Copper has a long history of use in medicine, and has continued to be used for purification of water, including use in hospitals to prevent legionnaires disease. The CDC pre released information on a study completed in March 2020 on the lifespan of COVID-19 on different surfaces which included its lifespan on copper, where it was completely dead within 4 hours. In addition, "Several reports demonstrated that Cu deficiency weakens the human immune response" 2. Given the multiple avenues of impact, it has been suggested that Cu supplementation, within recommended levels, be given to individuals who are low in Cu to help them fight off COVID-19. It is also possible that Cu supplementation, within recommended levels, may help prevent COVID-19 infection, or help individuals who are not low in Cu to fight off COVID-19 infection. However, dosage would have to be carefully managed, as excess levels of Cu can lead to both neurodegenerative and neurodevelopmental diseases.

Edible mushrooms form very nourishing meals especially for invalids, for they are easily digestible. They are consumed not only for their innate flavor and taste, but also for their important nutritional value, therefore, we analyzed the micronutrient contents of fresh and canned Agaricusbisporusand Pleurotusostreatus mushroom for their calcium, potassium and iron content. Fresh Agaricus was insignificantly higher in its calcium and iron contents (36.0 and 37.5 mg/100g; respectively) than Pleurotus(33.8 and 29.8 mg/100g) although the later was significantly higher in its potassium content (3890.4 mg/100g) versus 3102.9 in Agaricus. The micronutrient content of the canned Agaricus was higher than the canned cut Pleurotus. As these species of mushrooms are good sources of calcium, potassium, and iron, so they can be used as supplementary healthy foods for human nutrition.

There is increasing evidence of the prevalence manifestations of metabolic syndrome worldwide. Metabolic syndrome is a cluster of abnormalities characterized by hypertension, central obesity, insulin resistance, endothelial dysfunction, dyslipidemia and oxidative stress. All these alterations predispose individuals to type 2 diabetes and cardiovascular disease that are major contributing factors to earlier mortality among people. The investigation of food nutrients that could reverse the features of metabolic syndrome is an important aspect for dietary-based therapies that may ameliorate the burden of the disorder. Antioxidant micronutrients are of great interest due to the recent described association between obesity, cardiovascular alterations and oxidative stress. These antioxidant nutrients are also being considered in the management of metabolic syndrome due to their potential benefits on hypertension, insulin resistance and hypertriglyceridemia since growing evidence has emerged that point to a causal link between oxidative stress and metabolic syndrome. Thus, dietary antioxidant supplements could have favourable effect on the attenuation and prevention of the manifestations of metabolic syndrome traits. Therefore, the present review focuses on the importance of antioxidant micronutrients in the treatment and management of metabolic syndrome.

The high prevalence of anemia among children and adolescents in India is still an overwhelming problem. Not only that, there is also a considerable deficiency of various micronutrients such as Vitamin A, Vitamin B12, Vitamin D, serum ferritin, Zinc and Folate etc. in children. These micronutrients have several functional roles for the normal growth and development of children. Unfortunately, recent studies on public health and nutrition intervention have so far focused less on these micronutrition and more on anemia and nutrition. Data for this study obtained from the Comprehensive National Nutrition Survey (CNNS 2016-18), a nationally representative survey covering different age group. Specifically, it includes information on 9767 children aged 1-4 years. Out of these surveyed children biomarker data for hemoglobin, serum ferritin, zinc, folate, vitamin A, vitamin B12 and Vitamin D were collected from 8242 children. Micronutrient deficiencies were identified based on WHO and other established cut-off criteria. Wealth quintiles were computed to identify household economic inequality. The prevalence of anemia at the national level was 40.7%. Among micronutrients, folate (22.9%) and zinc (18.7%) deficiencies were most commonly observed, followed by vitamins A (18.3), vitamin B12 (13.8%) and vitamin D (14.0%). Iron deficiency as measured by ferritin was present in 31.6% of children. It is alarming that nearly one in three children (32.8%) suffer from deficiencies in two or more micronutrients. Clear socioeconomic disparities were observed for all micronutrient deficiencies (MND); children in the poorest groups had significantly higher levels of micronutrient deficiencies than children in the richest groups. Among the states, Gujarat and Madhya Pradesh had the highest overall micronutrient deficiencies, while West Bengal and Kerala had the lowest. This clearly shows that a large proportion of preschool children in India suffer from anemia and MND, with the prevalence being even more alarming in lower socio-economic settings. This study suggests that there is a need to move beyond single-nutrient interventions and implement comprehensive, multi-micronutrient supplementation or food fortification strategies seamlessly into the existing national health and nutrition programs.

The growing population demands and environmental concerns associated with traditional protein sources have prompted the exploration of alternative and sustainable food sources. The purpose of this comprehensive review is to highlight the nutritional benefits and sustainability of insect-based foods as a promising solution. Global population growth necessitates innovative approaches to meet the demand for nutritious and sustainable protein sources. There are numerous challenges associated with traditional livestock farming, including land use inefficiency, high water usage, and greenhouse gas emissions. As a result, edible insects have emerged as a viable alternative, providing proteins (35-77% of dry matter), healthy fats (10-50%), essential amino acids, and micronutrients such as iron (up to 31mg/100g) and zinc (up to 20mg/100g), vitamins, and minerals. In contrast to livestock, which requires 22,000-43,000 liters of water to produce 1 kg of beef, insect farming consumes significantly less water and land resources. Insects have the potential to address nutritional deficiencies and strengthen food security as they are recognized for sustainable production. The study thoroughly investigates the literature addressing environmental and sustainability concerns associated with edible insect farming, using a rigorous bibliometric and scientometric analysis via Vos viewer. With the help of Vos Viewer, it was possible to identify the geographical distribution of countries that contributed to the field of edible insects and their acceptance, as well as the top ten documents in this field with the most citations and mostly used keywords in this field of research. Future research and implementation strategies will be able to benefit global food security and environmental conservation through these alternative protein sources.

We report 2 cases of vitamin B12 deficiency in children due to deficient intake. These were 2 girls aged 4 years (case 1) and 6 years (case 2), respectively, hospitalized in December 2020 and March 2021 in the pediatric ward of Le Dantec hospital. Both patients presented with aregenative anemia, melanoderma and undernutrition. The bone marrow count in case 1 showed a dysmyelopoiesis with megablastosis. The blood vitamin B12 level was low in both cases. Folic acid blood levels were normal in both patients, but an associated martial deficiency was found in case 2. The dietary survey revealed a lack of intake of animal products rich in vitamin B12. Vitamin B12 replacement therapy was effective with rapid regression of all clinical signs observed in both children. The control of the vitamin B12 level after 1 month of treatment was normal in both patients. The disappearance of the symptoms under substitute treatment confirmed the deficiency of Vitamin B12 intake in both patients. Conclusion: Both of our patients had a profound Vitamin B12 deficiency in a context of deficiency in nutrition. The regression of the symptoms was spectacular under vitamin B12 replacement therapy, confirming the deficiency. We recommend in our context a contribution in micronutrients such as vitamins in children after weaning to avoid dietary errors.

Acute malnutrition affects nearly 52 million of under five years children globally, 75% of them live in low to middle income countries. The treatment of acute malnutrition using supplement foods could help children recovering and could reduce the risk of sickness. The present study investigated the factors associated with recovery among children with moderate acute malnutrition (MAM) under a follow-up program at health facilities. A prospective study was conducted in 16 health centers of Kirehe District of Rwanda and included 200 children from 6 to 59 months. A semi-structured questionnaire was used for data collection. All children enrolled in the study spent three months in nutrition program at health centers. The results show that after 3 months in the program 77.5% recovered from MAM. Children aged above 36 to 59 months were recovered at 90% whereas children aged from 24-35 months were recovered at 73.5%. Micronutrients and deworming provided at health facility were contributed to the recovery as children who received them were recovered at 89.1% and for those who didn’t were recovery at 72.1%. The findings demonstrated that boys were 16 times more likely to recover from MAM in three months of intervention than girls (AOR=16.19, p<0.001, 95% CI: 5.39- 48.63). Children from moderate income families were 3 more likely to recover than those from very low income families (AOR=2.8, p=0.029, 95% CI: 1.11-7.51). Male gender, receiving micronutrients and deworming from health facilities and family income status were factors associated with MAM recovery status

Objectives: World has witnessed a considerable increase in the proportion of elderly population.Aging is associated with decreased physical activity and metabolism and thereby the changes in the nutritional requirements of older adults.The objective of this communication was to assess the nutritional status of rural elderly population in India. Methodology: A community based cross-sectional study; adopting multistage stratified random sampling procedure was carried out by the National Nutrition Monitoring Bureau (NNMB), during 2005-06 among the rural population of nine major states of India. A total of 3871 older adults were covered for anthropometry and of them, a total of 2138 older adults were covered for dietary assessment. Key Results: In general, the consumption of all the foods was below recommended daily intakes (RDI), and the in-adequacy (<70% of RDI) of intake was high with respect to leafy vegetables, milk & milk products, fats & oils and sugar & jaggery. Similarly, the in-adequacy of intakes of micronutrients such as vitamin A, iron, riboflavin and free folic acid was high among both genders. The poor intake of diet was reflected in high prevalence of chronic energy deficiency (CED) among the rural elderly in India. Conclusions: In general,the rural elderly were subsisting on inadequate diets in terms of both quantity and quality. Similarly, the prevalence of CED among elderly is a ‘‘very high’’ public health nutrition problem in India. Therefore, the Government of India should initiate appropriate nutrition intervention measures to improve the overall nutritional status and special nutrition policies to address the health and nutritional problems of the aging population.
