Average daily food intakes of 90 rural pregnant women belonging to arid, semi-arid and wet zones of Haryana State, Northern India have been determined. As a result of questionnaires and interviews, food intake for three consecutive days were collected. Intakes of cereals, pulses, roots and tubers, other vegetables and sugar and jaggery by the respondents were significantly lower than the prescribed Indian Recommended Dietary Intakes (RDI). The consumption of milk and milk products and fats and oils was significantly higher than that of RDI whereas, green leafy vegetables and fruits were the most limited food items. As the diets of rural pregnant women were inadequate with respect to some food groups, which resulted in lower intake of protein, β-carotene and ascorbic acid. Despite their poor intake their weights and heights were not much below the standards. BMI classification projected that only about one fourth of the respondents were underweight. There is pressing need to educate rural pregnant women regarding their increased nutritional requirements.

Background/Objective: Vegetables and fruits play a highly significant role in food security of the underprivileged in both urban and rural settings. The study was designed to determine the nutritional composition of some neglected underutilized fruits and vegetables in Southeast geopolitical zone of Nigeria. Methodology: The commonly occuring underutilized fruits and vegetables were selected for the study. The food crops were harvested and identified at the Herbarium in the Department of Plant Science and Biotechnology, University of Nigeria Nsukka. Twenty underutilized fruits and vegetables each were cleaned and analysed for nutrients composition using standard methods. Data were presented using descriptive statistics, percentage, mean, standard deviation and frequency. Results: The proximate composition of the fruits ranged from 54.34-80.30% moisture, 0.27-6.21% protein, 0-3.08% fat, 0.28-8.58 % fibre, 0.33-11.05% ash and 9.08-36.61% carbohydrate. The ranges for mineral values of the fruits were iron 0.10-9.60 mg, zinc 0.02-10.30 mg, manganese 0.10-6.60 mg and calcium 5.42-46.50 mg.  The vitamin contents of the fruits ranged from beta-carotene traces -5666.67 RE, ascorbic acid 0-48.82 mg and vitamin E 0 -11.99 mg. The proximate composition of the vegetables ranged from moisture 60.45-91.00%, protein 0.02-6.60%, fat 0.02-2.19%, fibre 0.04-5.01%, ash 0.04-4.20% and carbohydrate 10.30-36.61%. The ranges for mineral values of the vegetables were iron 1.40-14.80 mg, zinc trace-9.40 mg, manganese 0.07-4.80 mg and calcium 18.19-400.00 mg. The vitamin levels of the vegetables were beta-carotene 15.20-1933.33 RE, ascorbic acid 2.40-38.40 mg and vitamin E traces - 6.67 mg. Conclusion: The use of these fruits and vegetables should be encouraged particularly in areas where they are not produced through nutrition education in order to promote the food use of these crops.

AbstractWe aimed to investigate the trends of breast milk lutein concentrations at different times and their relationship with dietary lutein intake during the 12 weeks after delivery. Breast milk samples were collected from thirty-seven mothers at 4, 8 and 12 weeks postpartum. A HPLC detection method was used to measure breast milk lutein concentrations. Dietary intake was assessed using an FFQ, and then dietary lutein intake was calculated. The correlations between dietary lutein intake and breast milk lutein concentrations during lactation were investigated by Pearson’s correlation coefficient. General linear regression models were used to evaluate the optimal regression equation. The mean values of dietary lutein intake at 4, 8 and 12 weeks postpartum were 5·22 (sd 3·60), 7·28 (sd 4·30) and 7·33 (sd 4·24) mg/d, respectively. The mean values of breast milk lutein concentrations at 4, 8 and 12 weeks postpartum were as follows: 46·41 (sd 41·36), 57·96 (sd 40·00) and 62·33 (sd 30·10) μg/l, respectively. Breast milk lutein concentrations were positively associated with dietary lutein intake at 4 weeks postpartum (r 0·527, P < 0·05), which was consistent with the positive correlations observed at 8 and 12 weeks postpartum (r 0·444, P < 0·05; r 0·468, P < 0·05) by the sensitivity analysis. Increased dietary lutein intake can increase the concentration of lutein in the breast milk, and women are recommended to increase their dietary intake of green leafy vegetables and fruits that are rich in lutein during the pregnancy and postpartum periods.

The Moringa oleifera has proven to be an ancient medicine for for anemia, skin infections, blackheads, anxiety, and pimples, for intestinal worms, lactation, diabetes and pregnancy. Green leafy vegetables and fruits provide much needed essential micronutrients. Moringa leaves in particular are a rich, inexpensive source of micronutrients. In teenage girls a large number of hormonal changes are witnessed and due to the change in diet which lacks the intake of leafy vegetables and fruits that are essential, a large number of anemic cases are observed. To overcome this problems moringa oleifera leaves extract was formulated. 10 girls of the age group ranging between 17-21 years were selected and their haematological investigation was done. Oral administration of this extract was continued for over a month to these girls. After a month haematological investigation were repeated. Haemoglobin of the moringa extract treated group when compared with the before treatment group were , found out to be increased due to the phytochemical constituents in the extract and also presence of minerals and vitamins.
