A Pilot School Meal Program Using Local Foods with Soybean in Rural Bangladesh: Effects on the Nutritional Status of Children

Growth retardation, which includes stunting, wasting, underweight and micronutrient deficiency, continues to be a major public health problem in most low-income countries. Growth retardation and micronutrient deficiency contribute to mortality, morbidity, reduced immune competence and impaired cognitive function and productivity.  

In Bangladesh, school feeding programs with fortified biscuits have been evaluated. However, the impacts of a school meal program using local foods on the growth and nutritional status of children have not been investigated. In this study, the authors aimed to determine whether a school meal program (SMP) using local foods with soybean could improve children’s growth and micronutrient status in rural Bangladesh.

Two primary schools were randomly assigned as intervention (SMP; n = 172) and control (non-SMP; n = 182) schools. Children in the intervention school were supplied a school meal with local foods including soybean, containing more than one-third of the recommended daily allowance of energy and nutrients, 5 days/week for 8 months. The attendance rate and school lunch consumption of the children were monitored. Sociodemographic data were collected at baseline only. Anthropometrical data and blood samples were collected from all children at baseline and at the end of the study.

The results demonstrated that there were no significant differences in anthropometric measurements at baseline between the intervention and control groups, but there were differences in the prevalence of anemia, vitamin A deficiency and zinc deficiency. After the intervention, children in the SMP school showed a larger degree of improvement in the height-for-age Z-score (P < 0.001), red blood cell count (P = 0.001) and hemoglobin concentration (P < 0.001) than children in the non-SMP school. However, there were no positive effects on the body mass index (BMI)-for-age Z-score, serum ferritin, serum retinol or serum zinc status among children in the SMP school. 

In conclusion, a school meal program using local foods with soybean improved the height velocity and hemoglobin concentration of children in rural Bangladesh. In addition, these findings support the positive effects of school meal program with local foods which contain adequate nutrients on improving nutritional status of children in low-income countries.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...
