Development of international criteria for a front of package food labelling system: the International Choices Programme

BACKGROUND: A global push to reduce the amount of saturated and trans-fatty acids, added salt and sugar in processed food, and to enhance fruit, vegetable and whole grain intake, while limiting energy intake, exists for most populations. OBJECTIVES: To redesign the International Choices Program (note: this is unrelated to the US Smart Choices Program), initially Netherlands focused, by an international board of scientists to create a generic, global front-of-pack nutrition logo system that helps consumers make healthier food choices and stimulates product reformulation. METHODS: The Programme is a product-group-specific-nutrient-profiling approach with a distinction between basic and discretionary foods. The basic product groups are main contributors of essential and beneficial nutrients, and are based on food-based dietary guidelines from more than 20 countries across the globe. Generic criteria are derived from international nutrient recommendations for trans-fatty acids, saturated fatty acids, sodium, added sugar, fibre and energy, and evaluated against food composition data from 12 countries across Europe and market reality (actual foods on the market). Selected debates such as the source of fibre are also presented. RESULTS: Generic criteria and a decision framework were developed to further define food categories, so as to meet the unique country- and region-specific dietary needs. The result is a complete set of criteria that is evaluated on a regular basis to ensure its alignment with international dietary patterns, new scientific insights and current developments within the food market. CONCLUSIONS: These guidelines are currently used in a number of countries across the globe, and are being evaluated for effectiveness. Completed studies have demonstrated an increase in consumer awareness, a positive effect on product innovation and a potential impact on nutrient intakes

Trunk fat and leg fat have independent and opposite associations with fasting and postload glucose levels: the Hoorn study

Trunk fat and leg fat have independent and opposite associations with fasting and postload glucose levels: the Hoorn study. Snijder MB, Dekker JM, Visser M, Bouter LM, Stehouwer CD, Yudkin JS, Heine RJ, Nijpels G, Seidell JC; Hoorn study. Institute for Research in Extramural Medicine, VU University Medical Center, Amsterdam, The Netherlands. [email protected] OBJECTIVE: Waist and hip circumferences have been shown to have independent and opposite associations with glucose levels. Waist circumference is positively associated with glucose levels, whereas hip circumference is negatively associated. It is unclear which tissues are involved in the pathophysiological mechanism causing these associations. The main goal was to determine which tissue in the trunk and legs, fat or lean tissue, is associated with measures of glucose metabolism. RESEARCH DESIGN AND METHODS: In 623 participants of the third examination of the Hoorn Study, whole-body dual-energy X-ray absorptiometry was performed to determine fat and lean soft-tissue mass in the trunk and legs. Fasting and 2-h postload glucose levels after 75-g oral glucose tolerance test (OGTT) were determined. After exclusion of known diabetic patients, cross-sectional analyses were performed in 275 men aged 60-87 years (140 with normal glucose metabolism, 92 with impaired glucose metabolism; and 43 with diabetes) and in 281 women (148 with normal glucose metabolism, 90 with impaired glucose metabolism, and 43 with diabetes). RESULTS: Greater trunk fat mass was associated with higher glucose levels after adjustment for age, trunk lean mass, leg lean mass, and leg fat mass. Standardized beta (95% CI) in men were 0.44 (0.25-0.64) for fasting and 0.41 (0.22-0.60) for postload glucose. For women, these values were 0.49 (0.35-0.63) and 0.47 (0.33-0.61), respectively. In contrast, in the same regression models, a larger leg fat mass was associated with lower glucose levels. Standardized beta in men were -0.24 (-0.43 to -0.05) and -0.12 (-0.31 to 0.07) and in women -0.24 (-0.37 to -0.10) and -0.27 (-0.40 to -0.13) for fasting and postload glucose, respectively. In these models, larger leg lean mass was also associated with lower glucose levels but was only statistically significant in men. CONCLUSIONS: If trunk fat is taken into account, accumulation of fat in the legs seems to be protective against a disturbed glucose metabolism, particularly in women. Further research is needed to unravel underlying pathophysiological mechanism

A prospective study on obesity and subcutaneous fat patterning in relation to breast cancer in post-menopausal women participating in the DOM project.

The associations of body fat and body fat distribution with breast cancer risk were examined in a prospective study in 9,746 post-menopausal women with a natural menopause, aged 49-66 at intake, participating in a breast cancer screening project (the DOM project in Utrecht). During a follow-up period of 15 years (mean follow-up time 12.5 years) 260 women developed breast cancer. Fat distribution, assessed by contrasting groups of subcapsular and triceps skinfold thickness, was found to be unrelated to breast cancer incidence. No significant relationship between body fat, measured either by weight, Quetelet's index, triceps skinfold or subscapular skinfold, and breast cancer risk was found when analysed in quartiles. However, women in the upper decile compared with the lower decile of the distribution of Quetelet's index were found to have a 1.9 times (95% CI 1.1-3.3) higher risk for breast cancer. These results seemed to be in contrast with the significant positive association between fatness, analysed in quartiles, and breast cancer observed in a cross-sectional study, based on mammographic screening, carried out previously in the same population. Although the differences between the present, prospective, study and our cross-sectional study may be due to chance it may be that there are differences between characteristics of breast cancer detected at screening and subsequently, which influence the associations between measures of fatness and risk of breast cancer

Etnografía en la “Ecoferia la Tierra Sabe”: un estudio de subjetividades emergentes

Este trabajo presenta los resultados parciales e interrogantes surgidos en una investigación realizada en el marco de una Beca de Experiencia Laboral de la FCNyM llevada a cabo durante el corriente año. El objetivo principal es analizar y describir las prácticas que tienen lugar en el espacio público del Jardín Botánico del Parque Saavedra de La Plata, focalizando en los discursos y representaciones en torno a los estilos de vida y hábitos de consumo de los actores presentes en el espacio. En los últimos años la ciudad de La Plata es escenario de la conformación de un circuito “alternativo” (Magnani, 2014), caracterizado por la emergencia y proliferación de espacios de producción, distribución y consumo en donde participan diversos actores con propuestas culturales, educativas y comerciales que promueven formas de gestionar la alimentación y la salud y maneras de organizarse que buscan escapar de las prácticas y discursos hegemónicos. Dentro de este circuito podemos trazar una red de espacios que incluyen centros culturales, emprendimientos productivos autogestivos, centros o institutos de terapias alternativas, entre otros. En las páginas siguientes narraré la historia del surgimiento del mercado alternativo en el Jardín Botánico, dando cuenta de los diversos actores y discursos que jugaron en la configuración del mismo tal como existe en la actualidad. El relato nos permitirá observar cómo el espacio emerge, en primer lugar, a partir de un posicionamiento en relación a lo público, al consumo y a la búsqueda de un estilo de vida más saludable. Mostraremos cómo a partir de estos posicionamientos comunes llegan a confluir en él una gran cantidad de propuestas, a la par que se da cierta fragmentación respecto del modo de establecer y resignificar los vínculos con el Estado.Facultad de Humanidades y Ciencias de la Educació

Involving children in creating a healthy environment in low Socioeconomic Position (SEP) neighborhoods in The Netherlands:A Participatory Action Research (PAR) project

To ensure that health behavior interventions for children living in low socioeconomic position (SEP) neighborhoods are in line with children’s wishes and needs, participation of the children in the development, implementation, and evaluation is crucial. In this paper, we show how children living in three low SEP neighborhoods in the Netherlands can be involved in Participatory Action Research (PAR) by using the photovoice method, and what influences this research process. Observations, informal chats, semi structured interviews, and focus group discussions with children and professionals were done to evaluate the research process. The photovoice method provided comprehensive information from the children’s perspectives. With the help of the community workers, the children identified feasible actions. We found that it is important to constantly discuss the research process with participants, start with a concrete question or problem, and adapt the project to the local context and skills of participants

Ionospheric quasi-static electric field anomalies during seismic activity in August–September 1981

The paper proposes new results, analyses and information for the plate tectonic situation in the processing of INTERCOSMOS-BULGARIA-1300 satellite data about anomalies of the quasi-static electric field in the upper ionosphere over activated earthquake source regions at different latitudes. The earthquake catalogue is made on the basis of information from the United State Geological Survey (USGS) website. The disturbances in ionospheric quasi-static electric fields are recorded by IESP-1 instrument aboard the INTERCOSMOS-BULGARIA-1300 satellite and they are compared with significant seismic events from the period 14 August–20 September 1981 in magnetically very quiet, quiet and medium quiet days. The main tectonic characteristics of the seismically activated territories are also taken in account. The main goal of the above research work is to enlarge the research of possible connections between anomalous vertical electric field penetrations into the ionosphere and the earthquake manifestations, also to propose tectonic arguments for the observed phenomena. The studies are represented in four main blocks: (i) previous studies of similar problems, (ii) selection of satellite, seismic and plate tectonic data, (iii) data processing with new specialized software and observations of the quasi-static electric field and (iiii) summary, comparison of new with previous results in our studies and conclusion. We establish the high informativity of the vertical component <i>Ez</i> of the quasi-static electric field in the upper ionosphere according observations by INTERCOSMOS-BULGARIA-1300 that are placed above considerably activated earthquake sources. This component shows an increase of about 2–10 mV/m above sources, situated on mobile structures of the plates. The paper discusses the observed effects. It is represented also a statistical study of ionospheric effects 5–15 days before and 5–15 days after the earthquakes with magnitude M 4.8–7.9

Морфологічне дослідження впливу мелатоніну на стан слизової оболонки шлунка щурів в умовах експериментальної гастральної виразки

Введение серотонина вызывает в слизистой оболочке желудка животных острые деструктивные изменения преимущественно в виде эрозий и язв различного размера и численности, которые сопровождаются уменьшением содержания нейтральных мукополисахаридов в цитоплазме клеток поверхностно-ямочного эпителия. Введение мелатонина при гастральной язве уменьшает деструктивные изменения в слизистой оболочке желудка и восстанавливает состояние защитного слизистого барьера.Введение серотонина вызывает в слизистой оболочке желудка животных острые деструктивные изменения преимущественно в виде эрозий и язв различного размера и численности, которые сопровождаются уменьшением содержания нейтральных мукополисахаридов в цитоплазме клеток поверхностно-ямочного эпителия.

Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective

This Report has a number of inter-related general purposes. One is to explore the extent to which food, nutrition, physical activity, and body composition modify the risk of cancer, and to specify which factors are most important. To the extent that environmental factors such as food, nutrition, and physical activity influence the risk of cancer, it is a preventable disease. The Report specifies recommendations based on solid evidence which, when followed, will be expected to reduce the incidence of cancer

Small portion sizes in worksite cafeterias: do they help consumers to reduce their food intake?

Background:Environmental interventions directed at portion size might help consumers to reduce their food intake.Objective:To assess whether offering a smaller hot meal, in addition to the existing size, stimulates people to replace their large meal with a smaller meal.Design:Longitudinal randomized controlled trial assessing the impact of introducing small portion sizes and pricing strategies on consumer choices.Setting/participants:In all, 25 worksite cafeterias and a panel consisting of 308 consumers (mean age39.18 years, 50% women).Intervention:A small portion size of hot meals was offered in addition to the existing size. The meals were either proportionally priced (that is, the price per gram was comparable regardless of the size) or value size pricing was employed.Main outcome measures:Daily sales of small and the total number of meals, consumers self-reported compensation behavior and frequency of purchasing small meals.Results:The ratio of small meals sales in relation to large meals sales was 10.2%. No effect of proportional pricing was found B0.11 (0.33), P0.74, confidence interval (CI): 0.76 to 0.54). The consumer data indicated that 19.5% of the participants who had selected a small meal often-to-always purchased more products than usual in the worksite cafeteria. Small meal purchases were negatively related to being male (B0.85 (0.20), P0.00, CI: 1.24 to 0.46, n178).Conclusion:When offering a small meal in addition to the existing size, a percentage of consumers that is considered reasonable were inclined to replace the large meal with the small meal. Proportional prices did not have an additional effect. The possible occurrence of compensation behavior is an issue that merits further attention. © 2011 Macmillan Publishers Limited All rights reserved

The effects of a 25% discount on fruits and vegetables: results of a randomized trial in a three-dimensional web-based supermarket

<p>Abstract</p> <p>Background</p> <p>Lowering the price of fruit and vegetables is a promising strategy in stimulating the purchase of those foods. However, the true effects of this strategy are not well studied and it is unclear how the money saved is spent. The aim of this study is to examine the effects of a 25% discount on fruits and vegetables on food purchases in a supermarket environment.</p> <p>Methods</p> <p>A randomized controlled trial with two research conditions was conducted: a control condition with regular prices (n = 52) and an experimental condition with a 25% discount on fruits and vegetables (n = 63). The experiment was carried out using a three-dimensional web-based supermarket, which is a software application in the image of a real supermarket. Data were collected in 2010 in the Netherlands. Participants received a fixed budget and were asked to buy weekly household groceries at the web-based supermarket. Differences in fruit and vegetable purchases, differences in expenditures in other food categories and differences in total calories were analyzed using independent samples t-tests and multiple linear regression models accounting for potential effect modifiers and confounders.</p> <p>Results</p> <p>The purchased amount of fruit plus vegetables was significantly higher in the experimental condition compared to the control condition (Δ984 g per household per week, <it>p </it>= .03) after appropriate adjustments. This corresponds to a 25% difference compared to the control group. Both groups had similar expenditures in unhealthier food categories, including desserts, soda, crisps, candy and chocolate. Furthermore, both groups purchased an equal number of food items and an equal amount of calories, indicating that participants in the discount condition did not spend the money they saved from the discounts on other foods than fruits and vegetables.</p> <p>Conclusion</p> <p>A 25% discount on fruits and vegetables was effective in stimulating purchases of those products and did neither lead to higher expenditures in unhealthier food categories nor to higher total calories purchased. Future studies in real supermarkets need to confirm these findings.</p
