In recent years, the trend of growing vegetables on green roofs has gained momentum as a way of promoting agricultural sustainability in Dhaka City. Rooftop gardens become an important part of urban agriculture's recent rejuvenation and offer alternative spaces for urban markets to grow vegetable products. Green roofs create spaces for vegetable crop production, thereby creating opportunities for agricultural incorporation into urban communities. At present, however, vegetable production activities on rooftops are limited due to multiple challenges that need to be addressed before widespread implementation takes place. Rooftop agriculture can improve various ecosystem services, enhance the biodiversity of urban areas and reduce food insecurity. Food production from green roofs will help support and sustain food for urban communities and provide a rare opportunity to grow food efficiently in typically unused spaces. As human populations become more urbanized and urban consumers become more interested in local food for their families, the use of alternative agricultural production systems, such as green roof technologies, will increase in importance. While cultivating food on buildings is a key component of making cities more sustainable and habitable, green roofs are not the total solution for providing cities with food security. They should be viewed more as a supplement to other sources of food production in urban areas.

Purpose Energy drink (ED) consumption has become a common trend, especially among the youth. Hence, the purpose of this study was undertaken to assess the ED consumption pattern among the university students and investigate the independent predictors for their preference of such drinks. Design/methodology/approach It was a cross-sectional study conducted among 323 students from various departments of Noakhali Science and Technology University, Bangladesh. Findings Among students, about 57 per cent were male, and mostly between 21-23 years. About 31 per cent of the students had never consumed ED, while 69 per cent had consumed such drinks at least once in their lifetime. Only 31.4 per cent of the ever consumer had knowledge of its components, and 14.3 per cent of them did not know the negative effects of ED. Bivariate analysis identified the variables that were significantly associated with students’ consumption of ED. Taking the significant factors into a multivariate model, the risks of ED consumption were male gender (OR = 3.82; 95 per cent CI = 2.24 − 6.52), longer study duration in university (OR = 1.02; 95 per cent CI = 1.00 − 1.03) and doing regular physical activity (OR = 1.69; 95 per cent CI = 1.04 − 2.75). Originality/value High consumption of ED among university students is evident, yet their perception regarding components and potential health hazards of such drinks is opaque. This study results suggest the necessity of formulating policy and intervention strategies concentrating on the predictors of ED consumption to promote consciousness about ingredients and related health effects of ED among students of all levels in Bangladesh and other countries as well.

Aim: Ascorbic acid (vitamin C) is the most important food constituent because of its antioxidant and functional activity. The study aims to determine the Vitamin C content in commercially available fruit drinks collected from selected shops in Bangladesh. Study Design: This study is an experimental study.  Place and Duration of Study: The present study was conducted in the food analysis laboratory of Department Food Technology and Nutrition Science, Noakhali Science and Technology University, from January 2019 to May 2019. In the present study, a total of 22 branded different fruit drinks samples (orange, mango, lichi) were collected from the local market of Noakhali, Bangladesh. Methodology: Vitamin C was analyzed with the titrimetric method and Sugar content, pH was also successfully determined by refractometer, pH meter respectively. Results: The analyzed Vitamin C was found in the range of 2.96 to 70 mg/100 ml. Sugar content, pH was also successfully determined from the samples. The majority of the samples were found less in vitamin C concentration while only two samples (samples 3, 18) were found high the vitamin C concentration. Conclusion: From the above study, titrimetric analysis proves itself as a scientific method in the determination of vitamin C concentration in the samples.

Background Teachers play a pivotal role in imparting nutritional knowledge to their students. This research aimed to evaluate the nutrition-related knowledge, attitudes, and practices (KAP) of selected Bangladeshi school teachers across the country. Methods A cross-sectional study was performed using a multistage sampling method. A pretested and structured questionnaire was used to collect data. Statistical analyses, including descriptive statistics, multiple regression analysis, and ANOVA tests, were performed to carry out the study. Results Among the 280 participants, only 9.9% were happy with their understanding of childhood nutrition requirements, around 54.2% were familiar with basic nutrition-related knowledge, and overall, 97.7% of participants had a positive attitude towards learning about nutrition-related knowledge focusing on the well-being of children. Moreover, only 38.7% had training in pediatric nutrition. Age, type of school, type of residence, professional training of school teachers, and the intent of having ever taken part or paying attention to nutrition-related knowledge significantly impacted the respondents’ nutrition knowledge score (p<0.05). Conclusion Adequate planning and intervention measures should be developed to improve teachers’ understanding, behavior, and practice that encourage the growth of optimal nutrition-related behavior among school-aged children to establish a healthy nation.
