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.

Countries have become increasingly concerned about the safety of their food. Many countries have imposed standards on both domestically produced and imported food. In particular, countries have implemented regulations to control the quantity and quality of vegetable imports. Maximum Residue Limit (MRL) standards are one of the main restrictions adopted by numerous countries. Japan has one of the strictest MRL standards in the world. This study builds on previous studies to explore the impact of MRL standards on Japanese vegetable imports. Gravity models are used to analyze how MRL standards influence the Japanese imports of different types of vegetables (fruit vegetables, leafy vegetables, bulb vegetable, and root vegetables). The results reveal that the trade impacts of MRL standards are different for different types of vegetables, with the most significant impact on imports of leafy and fruit vegetables and the least significant impact on imports of bulb vegetables.

AbstractObjectiveThe present study aimed to investigate whether organic conversion in catering has positive effects on the nutritional quality of menus offered.DesignThe methodology was based on a self-administered questionnaire. The self-declared priority given to the use of organic foods was measured as the basis for assigning catering managers to one of two groups: ‘green’ or ‘non-green’ caterers. These groups were then compared with regard to the relative nutritional quality of the menu options offered to customers.SettingThe study was carried out among randomly selected Danish worksite catering outlets.SubjectsThe subjects participating in the study comprised 526 Danish worksite catering managers.ResultsThe results showed a strong correlation between caterers' ‘green-ness’ and the nutritional quality of the menu options offered. Green caters had more healthy options in their menus than non-green caters, which is likely to result in improved nutritional quality of the diets of end consumers. The reason for this may partly be the increased service training efforts that green caterers practise in order to be able to implement organic foods successfully. It may also be associated with the fact that the price premiums and availability of the organic products forces caterers to serve menus with higher amounts of root and non-green leafy vegetables, pulses and seasonal vegetables.ConclusionThe present findings suggest that organic conversion of public canteens may be a good opportunity to promote healthier eating in public catering.

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.

Background/Objective: Vegetables and fruits are important sources of protective substances, which are highly beneficial for the maintenance of good health and prevention of diseases. Phytochemicals are non-nutritive plant chemicals that have protective or disease preventive properties. The study was designed to determine the phytochemicals, In-vitro-bioavailability of beta carotene and anti-nutrient composition of some neglected underutilized fruits and vegetables in Southeast geopolitical zone of Nigeria. Methodology: The frequently occurred 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 phytochemicals, In vitro bioavailability of beta carotene and anti-nutrients composition using standard methods. Data were presented using descriptive statistics, percentage, mean, standard deviation and frequency. Results: The result showed that 0 - 40% of beta carotene were bioavailable in the fruits studied.  The antinutrient levels in fruits were cyanide (0.02-3.47 mg), oxalate 1.22-12.38 mg and phytate traces- 12.60 mg. The range of phytochemicals in the fruits were tannins trace-10.40 mg, flavonoids 0-0.10%, saponins trace-0.051 mg, lycopene trace-94.20 mg, and phenol 0-4.01mg. The antinutrient levels in vegetables were cyanide 0.35-13.20 mg, oxalate 2.27-24.69 mg and phytate traces- 2.57 mg.  The result showed that 22- 68.80% of beta carotene were bio available in the vegetables studied. The phytochemicals in the vegetables were tannins 0.10-10.30 mg, flavonoids trace-0.20%, saponins trace-0.10 mg, lycopene trace-31.20 mg and phenol 0.01-3.31 mg. Conclusion: The use of these neglected fruits and vegetables is imperative because of their nutritional and health benefit.
