In Western societies scientists are increasingly expected to seek media exposure and cooperate with industry. Little attention
has been given to the way such expectations affect the role of scientific experts in society. To investigate scientists’ own
perspectives on these issues eight exploratory, in-depth interviews were conducted in Denmark with reputable nutrition scientists.
Additionally, eight interviews were held with ‘key informants’ from the field of nutrition policy. It was found that nutrition
scientists experience two dilemmas: first, between their aspiration to make a collective impact on public health and the powerful
incentives of each to appear frequently in the media with new messages; second, between their need to cooperate with the food
industry for financial reasons and their fear that this may compromise their independence and scientific integrity. It is
argued that the dilemmas identified in this study should be dealt with openly by the relevant groups of scientists. 相似文献

AbstractThe aim of this study was to quantify the food intake of an International Cyclist Union (UCI) World Tour professional cyclist team and to analyse changes in body composition during the Tour of Spain. Nine male professional road cyclists (31.3?±?3.0 years) volunteered to participate in the study. Nutritional data were collected each day throughout the 3-week Tour by two trained investigators who weighed the food ingested by the cyclists. Mean nutritional intake of the cyclists was as follows: carbohydrate, 12.5?±?1.8?g/kg/day of body weight (BW) (65.0?±?5.9%); fat, 1.5?±?0.5 g/kg/day BW (17.9?±?5.6%); and protein, 3.3?±?0.3?g/kg/day BW (17.1?±?1.6%). Intake of all micronutrients, except for folate, vitamin D and potassium (which were 78.7%, 46% and 84% of Recommended Dietary Allowances (RDA), respectively), exceeded the RDA. Height, weight, skinfolds, circumferences and diameters were taken following the guidelines outlined by the International Society for the Advancement of Kinanthropometry. Body density, body fat percentage, muscle mass, total muscle mass and fat mass of the arms and thighs were calculated. Percentage body fat, fat mass and upper arm fat mass significantly decreased (p < .05) after the Tour independent of the equation method used in the calculations. Total muscle mass remained unchanged. Generally, this sample of cyclists consumed more protein and less fat than the recommended amount and had low weight, BMI and fat mass. It is suggested that sports nutritionists design personalised diets in order to maintain a correct proportion of nutrients as well as controlling possible anthropometrical changes that could affect performance. 相似文献

Objectives
To examine how the subject of nutrition is being addressed in the work with children at risk of poor nutrition in educational institutions and what the barriers are which may hinder inclusion of this subject.Methods
A structured questionnaire was constructed for the purpose of this study and was implemented with 111 students in Israel who are working in their internships in educational institutions with children who are exposed to risk factors of poor nutrition (e.g., parental neglect, lack of knowledge, poverty).Results
Participants attributed a high level of importance to integrating nutrition-related components in their work. However, the findings indicate less emphasis on nutrition-related components than on psycho-social-educational components, as well as a low level of collaboration with specialists in the area of nutrition. In addition, it was found that knowledge-based barriers and institutional-related systemic barriers may hinder future teachers’ capabilities to incorporate those components despite their favorable approach towards this subject.Conclusions
The findings illuminate the need to reduce barriers hampering the individual work with children at risk of poor nutrition in educational institutions.Practice implications
In the training of future teachers, there is a need to advance a bio-psycho-social educational approach incorporating a knowledge base about assessing situations of poor nutrition, including how to advance an interdisciplinary collaboration with specialists in the area of nutrition. 相似文献26.

用模糊数学的方法确定甜玉米采收期 总被引：3，自引：0，他引：3
章在对乳熟期甜玉米25项营养成分进行动态分析的基础上,说明了仅以水分和糖分确定甜玉米采收期的局限性。采用模糊数学的方法-以多种营养素计频数来确定甜玉米的采收期,结果表明：普甜玉米适宜采收期为DAP18-21天,最佳采收期为DAP19天,当加工中对某种营养成分有特殊要求时还可增加其权重,择时采收。 相似文献
