Green leafy vegetables are important component of human diets, providing fibre, minerals and vitamins. Recently, non-conventional food plants are incorporated in diet to provide not only nutrient but also traditional treatment for various ailments. In a way to combat the devastating effect of malnutrition, there should be a long term intervention such as dietary diversification which can be achieved by increasing the production of locally produced foods and non-conventional vegetables. This study analysed the nutritional composition and anti-oxidant potential of Heliotropium indicum L. (Lamiales: Boraginaceae). The proximate analyses were carried out using the methods described by the Association of Official Analytical Chemist (AOAC). Vitamins were quantified by high performance liquid chromatography (HPLC). Mineral content were determined by Atomic Absorption Spectrophotometric (AAS) technique. The anti-oxidant activity was tested spectrophotometrically using ascorbic and gallic acid as standards. The nutrient constituents revealed that the fat content ranged between 0.67% +/- 0.05% and ash content ranged between 15.7% +/- 0.04%. Varying levels of vitamins like ascorbic acid, retinol, tocopherols, riboflavin, thiamine and niacin was quantified in the samples. Ascorbic acid content ranged between 622.6 mg/100 g. The aqueous extracts of the samples significantly (P < 0.05) inhibited DPPH radical with an IC50 value of 38 ug/mL. It is evident from this study that these indigenous leafy vegetable which are not widely known and consumed are of high nutritional quality and anti-oxidant potential. This vegetable can contribute significantly to the nutrient requirement of man and could complement the conventional ones in enhancing food security and sustainable livelihood. Hence, their cultivation and consumption should be encouraged.

Now-a-days consumption of plant-based foods, including green leafy vegetables are being considered as part of a healthy diet and importance is given on this by almost all health regulatory bodies of the developed countries. The plant, Emilia sonchifolia belongs of the family, Asteraceae. Nutritional composition of the plant and presence of some essential major elements were analyzed by using standard methods. Freshly collected healthy plants were subjected to assessment for different parameters and nutritional content such as moisture, fat, ash, protein, crude fiber, carbohydrate and energy value as well as probable mineral contents. After nutritional assessment it was revealed that, the contents of total moisture, fat, ash, protein, fiber and carbohydrate were 83.18%, 0.938%, 2.84%, 3.11%, 2.84% and 7.042%, respectively. The total energy content of the plant was 52.624 kcal. The results of the nutritional assessment of E. sonchifolia were near to the popular edible spinach of Amaranthus which contained moisture 81.8 - 83.9%, fat 0.3 - 0.5%, ash 2.8 - 3.6%, protein 4.1 - 4.8%, carbohydrate 4.3 - 5.2%, and energy 47 - 51 kcal. Concentration of macro minerals calcium (Ca), potassium (K), magnesium (Mg) and sodium (Na) was found to be 310, 137, 119 and 55 mg/100g, respectively whereas the concentration of micro minerals iron (Fe), copper (Cu), zinc (Zn), manganese (Mn) and chromium (Cr) was observed as 29, 0.17, 1.21, 1.52 and 0.20 mg/100g, respectively which was between the recommended limit.

Dietary Requirements

The supply of nutrients and proximate matter is insufficient to fulfil the dietary needs of the quickly expanding human population. Green leafy vegetables can prove economical sources of minerals, vitamins and fibers to overcome nutritional deficiencies. Five leafy vegetables (Brassica juncea, Spinacia oleracea, Trigonella foenum-graecum, Chenopodium album and Lactuca sativa) were collected from a horticulture garden and vegetable market for the evaluation of their proximate matter and nutritional composition. Their contents of proximate (moisture, ash, fats, fibers, carbohydrates and protein), minerals (Ca2+, K+ and P+) and anti-nutrients were examined using standard protocols. The contents of fats (0.43 mg g−1f.w.) in S. oleracea; fibers (0.8 mg g−1f.w.) in S. olerace; carbohydrates (0.89 mg g−1f.w.); in B. juncea, proteins (0.91 mg g−1f.w.) in L. sativa; and vitamin A (1.18 mg g−1f.w.) in C. album from the horticulture garden were high enough to meet the daily dietary requirements of adults. Tannins were higher in species collected from the market, which is toxic for human health. It is concluded that vegetables of horticulture garden grown in suitable environmental conditions possess better nutritional composition as compared to vegetables purchased from markets. However, a large-scale research is needed for the analysis of vitamins, minerals, antioxidants, anti-nutrients and heavy metals in leafy vegetables. Further research on ethnomedicinal attributes of leafy vegetables is recommended.

Fresh leafy vegetables which include Amarathus hybridus (Bush green), Telfairia occidentalis (Fluted pumpkin leaf), Vernonia amygdalina (Bitter leaf) and Pterocarpus mildbraedii (White campwood leaf) were subjected to spontaneous fermentation for 5 days at room temperature. Physicochemical properties (pH, temperature, and total titratable acidity) were monitored during the fermentation. It was observed that the pH (6.8 to 3.78) of all the vegetables decreased steadily as fermentation progressed. However, the temperature (27°C to 34°C) and total titratable acidity expressed as lactic acid equivalent (0.014-0.147) for all the vegetables increased as fermentation progressed. The percentage of occurrence of bacteria isolated from the fermenting mass include Bacillus spp. (39.1%), Lactobacillus spp. (26.1%), Escherichia coli and Staphylococcus spp. (8.7%), Proteus spp., Serratia spp., Citrobacter spp. and Pseudomonas spp (4.3%) respectively. The proximate composition and mineral contents of fermented and unfermented leaves were investigated. Significant increase in ash content was noticed for unfermented (8.07%-15.72%) and for fermented vegetables (12.50%-23.28%). The protein contents of T. occidentalis (24.29%-25.65%), and A. hybridus (14.27%-16.96%) increased significantly after fermentation. A decrease in fiber content was noticed for all fermented vegetables except for V. amygdalina where significant increase was noticed (10.97%-14.55%). Increase in both thiamine (1.37-1.52mg/ml) and niacin (1.32-1.62mg/ml) contents were observed in T. occidentalis after fermentation while significant reductions were recorded for A. hybridus and V. amygdalina. Generally, vitamin C content of the vegetables decreased during fermentation while some increases were recorded in the mineral content of fermented vegetables.

Purpose – The purpose of this paper is to analyze the nutritional composition and the acceptability of value-added products prepared from the dehydrated leaf mixture of underutilized green leafy vegetables (GLVs). GLVs are dense in micronutrients and are of great importance to the nutrition of population in developing countries. Nutritive value of commonly consumed GLVs has been studied extensively, but there is limited information available on nutritive value and acceptability of unconventional leafy vegetables. Design/methodology/approach – The nutritional potential and acceptability of leaf mixtures (LMs) prepared from the less-utilized leaves of beet root (Beta vulgaris), carrot (Daucus carota), cauliflower (Brassica oleracea) and turnip (Brassica rapa) which are usually discarded or are used as animal fodder were analyzed in the present study. The LM was prepared by mixing the powders of above-mentioned greens in a definite ratio (1:2:1:1). The LM was analyzed for the proximate, mineral composition (Ca, P, Fe, Cu, Zn, Mn and Mg) and antinutritional factors (oxalate and phenols). In total, 20 different recipes with different levels (0, 5, 10, 15 and 20 per cent) of LM incorporation were prepared and were assessed for quality on the basis of sensory attributes. Findings – The LM contains appreciable amount of proteins, fat, fiber, carbohydrate and calorific value, mineral elements and generally low levels of antinutrients. Products were well-accepted to the level of 10 per cent. Protein, iron and calcium content was significantly (p < 0.05) higher in the LM-incorporated recipes, and the increase was directly proportional to the level of LM incorporated. Originality/value – Dehydrated GLVs are concentrate source of micronutrients and can be used in product formulation. Value addition of traditional products with dehydrated GLVs can be advocated as a feasible food-based approach to combat micronutrient deficiencies.

Primary Infertility

Abstract This study assessed the rate of primary infertility and its associated factors among 402,807 currently married women aged 20–49 years in India using National Family Health Survey-4 data collected in 2015–2016. Dietary patterns and selected morbidities were included as independent variables, and socioeconomic variables were considered as covariates. Bivariate and multivariate analyses were done to estimate the prevalence of primary infertility and assess its association with the selected variables, respectively. The rate of primary infertility among currently married women in India in 2015–16 was 1.9% and this was significantly associated with younger age (<35 years), higher age at marriage (≥18 years), urban residence, higher secondary or above education and poverty. The consumption of dairy products (OR = 0.79, CI = 0.73–0.86), dark green leafy vegetables (OR = 0.57, CI = 0.39–0.81) and fruit (OR = 0.88, CI = 0.77–1.01) significantly reduced the odds of primary infertility. Daily consumption of fish and aerated drinks was related to 1.06–1.21 times higher odds of primary infertility. Overweight/obesity, high blood pressure and high blood glucose levels were associated with 1.08–1.21 times elevated odds of primary infertility. Thyroid disorder (OR = 1.38, CI = 1.21–1.60), heart disease (OR = 1.17, CI = 1.16–1.19) and severe anaemia (OR = 1.24, CI = 1.00–1.53) were associated with an increased likelihood of primary infertility among women (OR 1.17–1.39, CI 1.00–1.60). The findings provide compelling evidence that primary infertility among women is related to dietary patterns and morbidities. Interventions and programmes targeting the promotion of healthy diets and lifestyles could be beneficial in addressing the issue of primary infertility among women.
