Proposal for a World Food Policy Institute: Report of TAC Subcommittee
Report of a TAC subcommittee consisting of Sir John Crawford, W. David Hopper, Vernon W. Ruttan, and P.A. Oram. The report argued the need for an independent institute to keep the global food and agricultural situation under surveillance, to examine major food and agricultural policy and trade problems, and to identify and study important problems of food production and utilization. The report discusses the mandate, functions, research and training activities, organization, and funding of the proposed center. Agenda document discussed at TAC 8 and CGIAR International Centers Week July-August 1974, and again at the CGIAR meeting in October, 1974
Healthy Start vitamins—a missed opportunity:findings of a multimethod study
OBJECTIVE: To evaluate and provide a real-life view of the operation of the Healthy Start vitamins scheme. SETTING: The study took place in primary care and community settings that served rural, urban and ethnically diverse populations, in two sentinel sites: London, and Yorkshire and the Humber. An online consultation and stakeholder workshops elicited views from across England. PARTICIPANTS: 669 health and social care practitioners including health visitors, midwives, public health practitioners, general practitioners, paediatricians and support staff participated in focus group discussions (n=49) and an online consultation (n=620). 56 participants representing health and social care practitioners, policymakers, service commissioners, and voluntary and independent sectors took part in stakeholder workshops. METHODS: Three-phase multimethod study comprising focus group discussions, an online consultation and stakeholder workshops. Qualitative data were analysed thematically and quantitative data from the online survey were analysed using descriptive statistics. RESULTS: Study participants were concerned about the low uptake of Healthy Start vitamin supplements and the consequences of this for health outcomes for women and young children. They experienced Healthy Start vitamin distribution as logistically complex, requiring the time, resources and creative thinking of a range of local and regional practitioners from senior strategists to administrative support workers. In the light of this, many participants argued that moving to universal provision of vitamin supplements would be more cost-effective than the current system. CONCLUSIONS: There is consistency of views of health practitioners that the current targeted system of providing free vitamin supplements for low-income childbearing women and young children via the Healthy Start programme is not fulfilling its potential to address vitamin deficiencies. There is wide professional and voluntary sector support for moving from the current targeted system to provision of free vitamin supplements for all pregnant and new mothers, and children up to their fifth birthday
Improving the Nutritional Quality of Charitable Meals for Homeless and Vulnerable Adults: A Mixed Method Study of Two Meals Services in a Large English City
Inadequate nutrition may contribute to poor health in homeless and vulnerable adults. Charitable meals are critical to this group’s nutrition. The nutrient content of charitable meals at 2 organizations was assessed. Ethnography investigated organizational practice; semistructured interviews explored influences on meal provision. Meals were adequate for energy and the majority of nutrients but exceeded thresholds of saturated fat, salt, and sugars and lacked vitamin D and selenium in both organizations. Organizations were constrained by budget, equipment, food donations, volunteer capabilities, and time. Organizational values influenced meal provision; strategies to reduce fat, salt, and sugar content may be resisted because of an ethos of hospitality and overprovision
Calcium to phosphorus ratio, essential elements and vitamin D content of infant foods in the UK: possible implications for bone health
Adequate intake of calcium and phosphorus in the appropriate ratio of 1–2:1 (Ca:P), in addition to magnesium and vitamin D, is vital for bone health and development of infants. In this feasibility study, the ratio of Ca:P in conjunction with vitamin D and other essential elements (Cu, Fe, K, Mg, Na, and Zn) in a range of commercial infant food products in the UK was investigated. The elemental analysis was carried out using inductively coupled plasma optical emission spectrometry, and vitamin D levels were determined using an enzyme-linked immunosorbent assay. The quantitative data were further evaluated, based on a standardised menu, to measure the total daily intake of an infant aged 7–12 months against the Reference Nutrient Intake. The results from the study show that the Ca:P ratio of the infant's total dietary intake was within the recommended range at 1.49:1. However, the level of intake for each of the nutrients analyzed, with the exception of sodium, was found to be above the Reference Nutrient Intake, which warrants further investigation in relation to both micronutrient interactions and in situations where the intake of fortified infant formula milk is compromised. Finally, as the study is the first to include consumption of infant snack products, the level of total calorie intake was also calculated in order to assess the total daily estimated energy intake; the results indicate that energy intakes exceed recommendations by 42%, which may have implications for obesity
Understanding the role of carbohydrates in optimal nutrition
In recent years, the regulation of carbohydrate intake has become regarded as essential to achieve a balanced diet, with a range of health benefits attributed to low-carbohydrate diets. However, much of the advice on reduced carbohydrate intake does not reflect government-led dietary guidelines. As a result of this conflicting information, patients requiring assistance with weight management or glycaemic control may become confused about the appropriate carbohydrate intake, or be encouraged to experiment with ‘fad’ diets. As front-line healthcare professionals, nurses are in a prime position to advise patients on carbohydrate intake, as well as signposting them to evidence-based dietary resources. This article outlines the constituents of dietary carbohydrate, considers the health benefits of carbohydrates, and explains their importance as part of a healthy and balanced diet

Survey of the prevalence of Salmonella species on laying hen farms in Kosovo
A survey on the prevalence of Salmonella (S.) species was carried out on 39 layer farms in Kosovo between April and September 2012. In total 367 samples, comprising feces, dust, eggs, and internal organs from dead birds, were investigated using bacteriological culture methods. Additionally, data on the location of the farm, the total number of birds on the farm, age of birds, and laying performance were collected. Salmonella were isolated from 38 samples obtained from 19 (49%) farms. The most common serovar identified was Salmonella enteritidis, found on 18 farms. The most common S. enteritidis phage type was PT29 followed by PT6, PT7, PT21, PT13a, PT8, PT14b, and PT4. One S. enteritidis isolate was not typable. Six farms had more than one phage type. Furthermore, serovar S. Bovismorbificans also was found in samples from 3 farms. Flock size or production stage was not associated with the probability of isolating Salmonella. The only flock factor found to be significantly associated was percent hen/day production: It was 2.8 times more likely to isolate Salmonella from flocks with production above 80% hen/day production compared to flocks producing at a lower level. Analysis of antimicrobial resistance patterns of 30 isolates revealed that all isolates were sensitive to gentamicin, ampicillin, sulphamethoxazole trimethoprim, and oxytetracycline, and 29 (97%) were sensitive to ciprofloxacin. All isolates showed intermediate resistance or were resistant to minocycline and cloxacillin. Twenty-six isolates (86%) had intermediate resistance to amoxicillin and 27 isolates (90%) were fully resistant to streptomycin. The present survey revealed a high prevalence of Salmonella enteritidis in layer flocks in Kosovo, indicating that table eggs have to be suspected as an important source of human salmone-llosis
An exploration of knowledge, attitudes and advice given by health professionals to parents in Ireland about the introduction of solid foods. A pilot study
<p>Abstract</p> <p>Background</p> <p>For the purposes of this paper "weaning is defined as the introduction of the first solid foods to infants". Global recommendations by the World Health Organisation (WHO) recommend that all infants be exclusively breast-fed for the first six months of life. No global recommendations have been made for formula fed infants. In Europe it is recommended that weaning foods should be introduced between 18 weeks and 26 weeks regardless of whether infants are breast or formula fed. In the United Kingdom it is recommended that solids be introduced at around six-months for both breast and formula fed infants. In Ireland official guidelines recommend that breast fed infants should be introduced solids at 6 months of age while for formula fed infants the recommendation is for 4 months. The disparity between these global, European, UK and local recommendations may be a source of confusion for parents and health care professional based in Ireland. Emerging evidence suggests that babies in Ireland are given solid foods before the recommended age but there has been little investigation of the weaning advice provided by health professionals. Since community health professionals have routine parent interactions in the pre-weaning and early-weaning period and hence are in a unique position to positively influence parental weaning decisions, this study aimed to explore their knowledge, attitudes and advice practices about weaning.</p> <p>Methods</p> <p>A mixed-methods approach was used for the research, commencing with a multi-disciplinary focus group to guide and develop a questionnaire. Questionnaires were then distributed in a postal survey to General Practitioners (GPs) (<it>n </it>179), Practice Nurses (PNs) (<it>n </it>121), Public Health Nurses (PHNs) (<it>n </it>107) and Community Dieticians (CDs) (<it>n </it>8).</p> <p>Results</p> <p>The results indicate varying levels of knowledge of official weaning recommendations and a variety of advice practices. CDs and PHNs acknowledged a clear role in providing weaning advice while demonstrating high confidence levels in providing this advice. However, 19% of PNs and 7% of GP respondents did not acknowledge that they have a role in providing weaning advice to parents; even though Health Service Executive (HSE) written literature given to parents states that they should seek information from PNs and GPs.</p> <p>Conclusion</p> <p>Small pockets of misinformation about the introduction of solid foods persist amongst health professionals which may lead to inconsistent advice for parents. Further research is needed.</p
Aquatic food security:insights into challenges and solutions from an analysis of interactions between fisheries, aquaculture, food safety, human health, fish and human welfare, economy and environment
Fisheries and aquaculture production, imports, exports and equitability of distribution determine the supply of aquatic food to people. Aquatic food security is achieved when a food supply is sufficient, safe, sustainable, shockproof and sound: sufficient, to meet needs and preferences of people; safe, to provide nutritional benefit while posing minimal health risks; sustainable, to provide food now and for future generations; shock-proof, to provide resilience to shocks in production systems and supply chains; and sound, to meet legal and ethical standards for welfare of animals, people and environment. Here, we present an integrated assessment of these elements of the aquatic food system in the United Kingdom, a system linked to dynamic global networks of producers, processors and markets. Our assessment addresses sufficiency of supply from aquaculture, fisheries and trade; safety of supply given biological, chemical and radiation hazards; social, economic and environmental sustainability of production systems and supply chains; system resilience to social, economic and environmental shocks; welfare of fish, people and environment; and the authenticity of food. Conventionally, these aspects of the food system are not assessed collectively, so information supporting our assessment is widely dispersed. Our assessment reveals trade-offs and challenges in the food system that are easily overlooked in sectoral analyses of fisheries, aquaculture, health, medicine, human and fish welfare, safety and environment. We highlight potential benefits of an integrated, systematic and ongoing process to assess security of the aquatic food system and to predict impacts of social, economic and environmental change on food supply and demand
Campylobacter infection of broiler chickens in a free-range environment
Campylobacter jejuni is the most common cause of bacterial gastroenteritis worldwide, with contaminated chicken meat considered to represent a major source of human infection. Biosecurity measures can reduce C. jejuni shedding rates of housed chickens, but the increasing popularity of free-range and organic meat raises the question of whether the welfare benefits of extensive production are compatible with food safety. The widespread assumption that the free-range environment contaminates extensively reared chickens has not been rigorously tested. A year-long survey of 64 free-range broiler flocks reared on two sites in Oxfordshire, UK, combining high-resolution genotyping with behavioural and environmental observations revealed: (i) no evidence of colonization of succeeding flocks by the C. jejuni genotypes shed by preceding flocks, (ii) a high degree of similarity between C. jejuni genotypes from both farm sites, (iii) no association of ranging behaviour with likelihood of Campylobacter shedding, and (iv) higher genetic differentiation between C. jejuni populations from chickens and wild birds on the same farm than between the chicken samples, human disease isolates from the same region and national samples of C. jejuni from chicken meat
