An Assessment of the Potential Consumption Impacts of WHO Dietary Norms in OECD Countries

The member countries of the World Health Organization (WHO) have recently endorsed its Global Strategy on Diet, Physical Activity and Health. The strategy emphasizes the need to limit the consumption of saturated fats and trans fatty acids, salt and sugars, and to increase consumption of fruits and vegetables in order to combat the growing burden of non communicable diseases. Adherence to the norms recommended by the WHO would call for major changes in the consumption, production and trade of several key food products and several sectors of the food industry have expectedly raised serious concerns about the potential impact of these norms on their future growth prospects. This paper attempts a broad quantitative assessment of the consumption impacts of these norms in OECD countries using a mathematical programming approach. We find that adherence to the WHO norms would involve a significant decrease in the consumption of vegetable oils (30%), dairy products (28%), sugar (24%), animal fats (30%) and meat (pig meat, 13.5%, mutton and goat 14.5%) and a significant increase in the human consumption of cereals (31%), fruits (25%) and vegetables (21%). The paper also explains the apparent dilemma that some OECD countries face when simultaneously trying to liberalise agricultural markets and promote healthy diets.Food Consumption/Nutrition/Food Safety,

Farmers' perceptions about exotic multipurpose fodder trees and constraints to their adoption

Many organizations in Ethiopia have for many years promoted exotic multipurpose fodder trees (EMPFT) for livestock feed and soil improvement. Despite the apparent benefits, the number of farmers planting these trees was low. The objectives were to elucidate farmers¿ perceptions about their use value, management practices and constraints to adoption in three districts representing annual (one wheat-based and one teff-based) and perennial (coffee-based) crop-livestock systems in the Ethiopian highlands. Data were collected from 235 farm households. Most farmers (95.3%) had awareness of EMPFTs and the principal information sources were development agents (75.3%). Over half of the farmers were motivated to plant EMPFTs for feed value. Motivation for other purposes depended on cropping system, vegetation cover and availability of alternative local fodder trees in the area. Farmers had positive perceptions about EMPFTs for their feed value and contribution to soil conservation. Current adopters had a mean number of 587 (SE ± 84) EMPFTs per farm. Major constraints to adoption of EMPFTs were agronomic problems, low multipurpose value, and land shortage. Majority of farmers (89.8%) were interested to either continue or begin fodder tree development. Of the interested respondents, 44.5% preferred local fodder trees whereas 55.5% preferred EMPFTs. We conclude that farmers are aware of use values of EMPFTs while perceived constraints suggest that introduction of EMPFTs need consideration of farmers multiple criteria, but also awareness of feeding fodder trees and resource availability. Moreover, current development approaches have to recognize the importance of involving the end-users at all stages through participatory approaches to enhance adoptio

Lactococcus lactis M4, a potential host for the expression of heterologous proteins

Background: Many plasmid-harbouring strains of Lactococcus lactis have been isolated from milk and other sources. Plasmids of Lactococcus have been shown to harbour antibiotic resistance genes and those that express some important proteins. The generally regarded as safe (GRAS) status of L. lactis also makes it an attractive host for the production of proteins that are beneficial in numerous applications such as the production of biopharmaceutical and nutraceutical. In the present work, strains of L. lactis were isolated from cow's milk, plasmids were isolated and characterised and one of the strains was identified as a potential new lactococcal host for the expression of heterologous proteins. Results: Several bacterial strains were isolated from cow's milk and eight of those were identified as Lactococcus lactis by 16S rRNA sequence analysis. Antibiotic susceptibility tests that were carried out showed that 50% of the isolates had almost identical antibiotic resistance patterns compared to the control strains MG1363 and ATCC 11454. Plasmid profiling results indicated the lack of low molecular weight plasmids for strain M4. Competent L. lactis M4 and MG1363 were prepared and electrotransformed with several lactococcal plasmids such as pMG36e, pAR1411, pAJ01 and pMG36e-GFP. Plasmid isolation and RE analyses showed the presence of these plasmids in both M4 and the control strain after several generations, indicating the ability of M4 to maintain heterologous plasmids. SDS-PAGE and Western blot analyses also confirmed the presence of GFP, demonstrating the potential of heterologous protein expression in M4. Conclusions: Based on the 16S rRNA gene molecular analysis, eight Gram-positive cocci milk isolates were identified as L. lactis subsp. lactis. One of the strains, L. lactis M4 was able to maintain transformed low molecular weight plasmid vectors and expressed the GFP gene. This strain has the potential to be developed into a new lactococcal host for the expression of heterologous proteins

Road-based goods transportation : a survey of real-world logistics applications from 2000 to 2015

The vehicle routing problem has been widely studied from a technical point of view for more than 50 years. Many of its variants are rooted in practical settings. This paper provides a survey of the main real-life applications of road-based goods transportation over the past 15 years. It reviews papers in the areas of oil, gas and fuel transportation, retail, waste collection and management, mail and package delivery and food distribution. Some perspectives on future research and applications are discussed

Factors associated with clinically significant hyperbilirubinemia among abo-incompatible newborns at a tertiary care hospital in Kenya.

Background: ABO incompatibility is one of the most common causes of immune-mediated neonatal jaundice. It occurs in approximately 20-25% of all pregnancies. Literature shows that 60- 80% of newborns will develop physiological jaundice within the first week of life. Globally, the incidence ranges from 10-41%. Early detection of newborns with ABO incompatibility-related jaundice can prevent the incidence of bilirubin-induced neurological dysfunction. Whereas there have been extensive published data on rhesus isoimmunization, very few studies have examined ABO incompatibility and isoimmunization. From the published literature, there has been no known study that has assessed risk factors for developing clinically significant jaundice amongst ABO-incompatible neonates in the Kenyan context. Objectives: To determine the factors associated with clinically significant hyperbilirubinemia among ABO-incompatible newborns at a tertiary care hospital in Kenya. Methods: An unmatched case-control study was conducted amongst neonates with blood group A or B who were born to mothers with blood group O positive between March 2016 and December 2022. Consecutive sampling was done until the desired sample size of 83 cases and 83 controls was achieved. Factors such as gestational age, baby’s blood group, mode of feeding, gender, direct Coombs test, mother’s gravidity, and the mode of delivery were obtained from the medical records. Data was collected using a data collection form and entered into Microsoft Excel. Results: One hundred and sixty-six participants were recruited, comprising 83 cases and 83 controls. Only three of the factors studied were associated with clinically significant jaundice among ABO-incompatible newborns. Mixed feeding with an adjusted OR of 40.22 (CI 5.67-283.95), P= Conclusions: Isoimmunization caused by ABO hemolytic disease in the newborn has been overlooked as a disease. In the ABO setup, newborns with a positive direct Coombs test, a high reticulocyte count, and mixed or formula feeding are more likely to develop severe jaundice. Therefore, caution should be used when providing for newborns with the abovementioned risks. ABO incompatibility-related jaundice in high-risk infants should be risk-stratified, and prompt interventions should be taken

Organic Farming and Climate Change

This publication concludes that organic agriculture has much to offer in both mitigation of climate change through its emphasis on closed nutrient cycles and is a particularly resilient and productive system for adaptation strategies. It also raises the issue of whether organic agriculture should be eligible for carbon credits under voluntary carbon offsetting markets and the Clean Development Mechanism
