The present paper provides an insight into the food value chain of three specific sectors (fruit and vegetables, poultry and rice) in the Dominican Republic. The Glocal methodology used for the study combines a global view with local conditions and thus it can be applied to food markets. Each of these food chains is analyzed by following traditional industrial organization theory, based on structure, conduct and performance. Regarding the specific case of the Dominican Republic, different sources of information are used to analyze the weaknesses of the studied chains, including direct interviews. The food value chains of fruit and vegetables, poultry and rice in the Dominican Republic show a lack of structure and they are undergoing changes; however, they also have great opportunities to improve efficiency by making some changes.

Induction of phase 2 detoxication enzymes [e.g., glutathione transferases, epoxide hydrolase, NAD(P)H: quinone reductase, and glucuronosyltransferases] is a powerful strategy for achieving protection against carcinogenesis, mutagenesis, and other forms of toxicity of electrophiles and reactive forms of oxygen. Since consumption of large quantities of fruit and vegetables is associated with a striking reduction in the risk of developing a variety of malignancies, it is of interest that a number of edible plants contain substantial quantities of compounds that regulate mammalian enzymes of xenobiotic metabolism. Thus, edible plants belonging to the family Cruciferae and genus Brassica (e.g., broccoli and cauliflower) contain substantial quantities of isothiocyanates (mostly in the form of their glucosinolate precursors) some of which (e.g., sulforaphane or 4-methylsulfinylbutyl isothiocyanate) are very potent inducers of phase 2 enzymes. Unexpectedly, 3-day-old sprouts of cultivars of certain crucifers including broccoli and cauliflower contain 10–100 times higher levels of glucoraphanin (the glucosinolate of sulforaphane) than do the corresponding mature plants. Glucosinolates and isothiocyanates can be efficiently extracted from plants, without hydrolysis of glucosinolates by myrosinase, by homogenization in a mixture of equal volumes of dimethyl sulfoxide, dimethylformamide, and acetonitrile at −50°C. Extracts of 3-day-old broccoli sprouts (containing either glucoraphanin or sulforaphane as the principal enzyme inducer) were highly effective in reducing the incidence, multiplicity, and rate of development of mammary tumors in dimethylbenz(a)anthracene-treated rats. Notably, sprouts of many broccoli cultivars contain negligible quantities of indole glucosinolates, which predominate in the mature vegetable and may give rise to degradation products (e.g., indole-3-carbinol) that can enhance tumorigenesis. Hence, small quantities of crucifer sprouts may protect against the risk of cancer as effectively as much larger quantities of mature vegetables of the same variety.

This systematic review discusses data on the dietary intake of preschool children living in the Mediterranean countries of the European Union, including the comparison with a Mediterranean-like diet and the association with nutritional status. Specifically, data from the multinational European Identification and Prevention on Dietary and life style induced health effects in children and infants (IDEFICS) study and national studies, such as the Estudo do Padrão Alimentar e de Crescimento Infantil (EPACI) study and Geração XXI cohort in Portugal, ALimentando la SAlud del MAñana (ALSALMA) study in Spain, Étude des Déterminants pré-et postnatals précoces du développement et de la santé de l'ENfant (EDEN) cohort in France, Nutrintake 636 study in Italy, and Growth, Exercise and Nutrition Epidemiological Study in preSchoolers (GENESIS) cohort in Greece, were analyzed. In the majority of countries, young children consumed fruit and vegetables quite frequently, but also consumed sugared beverages and snacks. High energy and high protein intakes mainly from dairy products were found in the majority of countries. The majority of children also consumed excessive sodium intake. Early high prevalence of overweight and obesity was found, and both early consumption of energy-dense foods and overweight seemed to track across toddler and preschool ages. Most children living in the analyzed countries showed low adherence to a Mediterranean-like diet, which in turn was associated with being overweight/obese. Unhealthier diets were associated with lower maternal educational level and parental unemployment. Programs promoting adherence of young children to the traditional Mediterranean diet should be part of a multi-intervention strategy for the prevention and treatment of pediatric overweight and obesity.

The development of bone mass during the growing years is an important determinant for risk of osteoporosis in later life. Adequate dietary intake during the growth period may be critical in reaching bone growth potential. The Saskatchewan Bone Mineral Accrual Study (BMAS) is a longitudinal study of bone growth in Caucasian children. We have calculated the times of maximal peak bone mineral content (BMC) velocity to be 14.0 +/- 1.0 y in boys and 12.5 +/- 0.9 y in girls; bone growth is maximal similar to6 mo after peak height velocity. In the 2 y of peak skeletal growth, adolescents accumulate over 25% of adult bone. BMAS data may provide biological data on calcium requirements through application of calcium accrual values to factorial calculations of requirement. As well, our data are beginning to reveal how dietary patterns may influence attainment of bone mass during the adolescent growth spurt. Replacing milk intake by soft drinks appears to be detrimental to bone gain by girls, but not boys. Fruit and vegetable intake, providing alkalinity to bones and/or acting as a marker of a healthy diet, appears to influence BMC in adolescent girls, but not boys. The reason why these dietary factors appear to be more influential in girls than in boys may be that BMAS girls are consuming less than their requirement for calcium, while boys are above their threshold. Specific dietary and nutrient recommendations for adolescents are needed in order to ensure optimal bone growth and consolidation during this important life stage.

Four farmer groups for mango production and marketing were formed in 2002 in southern Vietnam in response to government support for the creation of market oriented farmer cooperatives. The role and structure of these groups is considered in terms of the degree to which they conform to internationally recognised principles for cooperative formation. Each of the farmer groups studied has evolved in different ways and their degree of compliance with the principles of cooperation varies widely. It is evident that state intervention and market forces may give rise to cooperative structures that differ from that intended under the principles surrounding cooperative law.

Previous studies indicate that regular consumption of a diet rich in fruits and vegetables is associated with a lower risk for age-related diseases. The aim of the present study was to evaluate whether the often-reported age-related decrease of plasma antioxidants in man depends on differences in dietary intake or on other age- and gender-related factors. In this observational case-control study, thirty-nine community-dwelling healthy subjects aged 65 years and older consuming high intakes of fruits and vegetables daily (HI) and forty-eight healthy subjects aged 65 and older consuming low intakes of fruit and vegetables daily (LI) were enrolled. Plasma levels of retinol, tocopherols, carotenoids and malondialdehyde (MDA) as well as content of protein carbonyls in Ig G were measured. Plasma levels of retinol, tocopherols and carotenoids were significantly higher in group HI than in group LI subjects independent of age and gender. MDA levels were inversely correlated with vitamin A and α-carotene. Protein carbonyls were inversely correlated with γ-tocopherol. In the elderly, a higher daily intake of fruits and vegetables is associated with an improved antioxidant status in comparison to subjects consuming diets poor in fruits and vegetables. Modification of nutritional habits among other lifestyle changes should be encouraged to lower prevalence of disease risk factors in later life. © The Authors 2005.

This paper emphasizes on the concept of innovation which is more and more nowadays recognized as of significant importance for all companies across different business sectors. The paper initially provides a review of the innovation literature in terms of types, classifications, and sources of innovation that have been proposed over time. Then, innovation in the context of the food industry is examined and it is attempted to identify innovation strategies followed by Greek food companies based on a value driven approach of innovation. The paper finally, provides insights from eight Greek food companies, which were selected from four subsectors: fruit and vegetables, dairy products, meat products (cured meats), and bakery products. The criterion used for the selection was market success and outstanding performance (e.g. market share, achieved results). Evidence indicates that companies tend to innovate along the dimension of offerings, which is more related to the traditional view of product and process innovation.

Data integration for the purposes of tracking, tracing and transparency are important challenges in the agri-food supply chain. The Electronic Product Code Information Services (EPCIS) is an event-oriented GS1 standard that aims to enable tracking and tracing of products through the sharing of event-based datasets that encapsulate the Electronic Product Code (EPC). In this paper, the authors propose a framework that utilises events and EPCs in the generation of "linked pedigrees" - linked datasets that enable the sharing of traceability information about products as they move along the supply chain. The authors exploit two ontology based information models, EEM and CBVVocab within a distributed and decentralised framework that consumes real time EPCIS events as linked data to generate the linked pedigrees. The authors exemplify the usage of linked pedigrees within the fresh fruit and vegetables supply chain in the agri-food sector.

O estudo apresentado avaliou a adequabilidade da ingesta de nutrientes e energia de estudantes do Instituto Politécnico de Santarém (IPS), através do preenchimento de um relatório alimentar de 24 horas, preenchido on line. Foram obtidas 103 respostas válidas para avaliação, maioritariamente do género feminino (77%), com uma idade média de 21 anos e valores de IMC normoponderais (78%). Cerca de metade dos participantes apresentou um estilo de vida sedentário. No geral, a alimentação caracterizou-se por elevados consumos de arroz, massa, batatas ou cereais de pequeno-almoço, de carne ou ovos, e consumos reduzidos de peixe, leguminosas e hortícolas crus ou cozinhados. O consumo de frutos e vegetais foi maioritariamente inferior ao recomendado, assim como a ingesta de energia e fibra. Ao contrário, a ingesta de lípidos totais e lípidos saturados foi superior ao recomendado na maioria dos participantes. A prevalência de inadequação de micronutrientes como cálcio, vitamina A, vitamina C e folatos foi próxima dos 50% ou superior. Perante os dados obtidos sugere-se uma melhoria dos hábitos alimentares e de estilo de vida, nomeadamente, o aumento do número de refeições realizadas, o aumento do consumo de frutos, hortícolas e leguminosas e o aumento da prática de atividade física.

Eating food prepared outside of the home has become the norm for adults on the island of Ireland. On 24% of eating or drinking occasions in the Republic of Ireland, food is cooked and prepared "out of the home". Bought-in cooked food makes up an average of 11% of a person’s energy intake in the United Kingdom. "Convenient" and "fast" cheap food has also become increasingly available to people. However, food prepared outside of the home has been found to contain considerably more dietary fat and less fibre and micronutrients than food prepared within the home. Traditionally, Indian diets are low in fat and high in fibre and rich in fruit and vegetables. However, these traditional meals have been adapted to suit Western palates and, as such, different ingredients in various quantities are added, potentially increasing their fat and salt content. Given the diversity of Indian takeaway dishes available on the island of Ireland, this survey has been designed to provide an insight into the energy (calorie), total fat, saturated fat, protein and salt content of the most popular starters, main courses and side dishes from various Indian takeaways and Indian restaurants with a takeaway service, as well as supermarkets or shop-bought equivalents. With two out of every three adults on the island of Ireland currently classified as overweight or obese, excess body weight is now one of the most important nutritional issues of our times. In addition to this, salt and fat intake is high and consumption of fruit, vegetables and fibre on the island of Ireland is low, increasing the risk of common chronic diseases, such as cardiovascular disease, diabetes and certain cancers. The consumption of excess calories and nutrient-poor foods contributes to our current obesity epidemic.

The Health Behaviours in School Children (HBSC) survey 2014 shows that overall health levels are good. There are encouraging findings on consumption of fruit and vegetables, teeth cleaning, and a drop in smoking levels and consumption of sweets and soft drinks.  However, many children said they find it easy to get cigarettes, too many children are going to bed hungry, and there are concerns about levels of cyber bullying. A total of 13,611 pupils were surveyed with questions on topics like general health, food and dietary behaviour, exercise and physical activity, self-care, smoking, use of alcohol and other substances, bullying including cyber bullying, and sexual health behaviours.

The First World War was won not just on the battlefields but on the Home Front, by the men, women and children left behind. This book explores the lives of the people of Pershore and the surrounding district in wartime, drawing on their memories, letters, postcards, photographs, leaflets and recipes to demonstrate how their hard work in cultivating and preserving fruit and vegetables helped to win the Great War. Pershore plums were used to make jam for the troops; but ensuring these and other fruits and vegetables were grown and harvested required the labour of land girls, Boy Scouts, schoolchildren, Irish labourers and Belgian refugees. When submarine warfare intensified, food shortages occurred and it became vital for Britain to grow more and eat less food. Housewives faced many challenges in feeding their families and so in 1916 the Pershore Women’s Institute was formed, providing many women with practical help and companionship during some of Britain’s darkest hours in history.
