In the late course of chronic pancreatitis (CP), weight loss is often seen because of reduced caloric intake and a reduction of pancreatic enzyme secretion, resulting in maldigestion. Most of these patients can be managed by dietary recommendations and pancreatic enzyme supplementation. However, approximately 5% of these patients are reported to be candidates for enteral nutrition support during their course of CP. Although small bowel access for enteral feeding can be easily obtained by percutaneous endoscopic gastrojejunostomy (PEG/J) or direct percutaneous endoscopic jejunostomy (DPEJ), to date there are no data regarding clinical outcome and safety of long-term jejunal feeding in CP.

Objetivo: determinar la ingesta de macronutrientes adecuada para mejorar el estado nutricional de las mujeres atletas y su rendimiento deportivo. Métodos: se realizó una búsqueda en cuatro bases de datos: EBSCO, Proquest, Pubmed y OvidSP, empleando las palabras clave “protein intake” AND “athletes” y “endurance athletes” AND “nutrition”. Criterios de selección: artículos originales sobre el consumo de proteínas en atletas femeninas (Entre 2009 y 2014), en revistas científicas indexadas. Resultados: se identificaron 722 artículos, de los cuales solo el 1,4% fueron considerados como incluidos. El 100% eran ensayos clínicos finalizados y publicados en el extranjero, el 50% en EE. UU. El 20% eran estudios exclusivos de mujeres atletas y el 80% incluían hombres y mujeres en la muestra. En el 70% de los estudios las mujeres atletas presentaron déficits energéticos; en la ingesta proteica, el 70% cumplieron con las recomendaciones dietéticas; la ingesta de hidratos de carbono fue inadecuada en el 90% de los ensayos clínicos y, en el 50%, las mujeres presentaban una sobreingesta de grasas. Conclusiones: existe una deficiencia de información acerca de la nutrición en mujeres atletas en Europa y a nivel internacional. Las atletas femeninas consumen energía y macronutrientes en menor proporción que los atletas masculinos. No existe consenso en el rango de proteínas recomendado y se encuentran discrepancias en el consumo en función del tipo de ejercicio físico que se realice. Se recomienda llevar a cabo un acuerdo entre instituciones científicas de prestigio sobre la ingesta energética y de macronutrientes en el deporte, especialmente en la mujer.

Aim: We aimed to explore the meaning of obesity in elderly persons with knee osteoarthritis (KO) and to determine the factors that encourage or discourage weight loss. Background: Various studies have demonstrated that body mass index is related to KO and that weight loss improves symptoms and functional capacity. However, dietary habits are difficult to modify and most education programs are ineffective. Design: A phenomenological qualitative study was conducted. Intentional sampling was performed in ten older persons with KO who had lost weight and improved their health-related quality of life after participating in a health education program. A thematic content analysis was conducted following the stages proposed by Miles and Huberman. Findings: Participants understood obesity as a risk factor for health problems and stigma. They believed that the cause of obesity was multifactorial and criticized health professionals for labeling them as “obese” and for assigning a moral value to slimness and diet. The factors identified as contributing to the effectiveness of the program were a tolerant attitude among health professionals, group education that encouraged motivation, quantitative dietary recommendations, and a meaningful learning model based on social learning theories. Conclusion: Dietary self-management without prohibitions helped participants to make changes in the quantity and timing of some food intake and to lose weight without sacrificing some foods that were deeply rooted in their culture and preferences. Dietary education programs should focus on health-related quality of life and include scientific knowledge but should also consider affective factors and the problems perceived as priorities by patients.

Primary Objective: To document the clinical characteristics of acute dysphagia in a group of pediatric patients after traumatic brain injury (TBI). Research Design: Prospective group study. Methods: Fourteen subjects (7 males, 7 females), aged 4 years 1 month to 15 years, with moderate or severe TBI (Glasgow Coma Scale [GCS] < 12). Subjects were assessed via clinical bedside examination documenting cognitive status, oromotor function, feeding function, dietary recommendations, and an indication of overall feeding severity Results: A pattern of impaired cognition, altered behavior related to feeding, severe tonal and postural deficits, oromotor, respiratory, and laryngeal impairments, and oral sensitivity issues was revealed. Conclusions: Swallowing impairment was affected by multilevel deficits, which both individually and in combination had a negative impact on swallowing competence and safety. In light of deficits identified, which could not be observed on videofluoroscopic investigation alone, this study highlighted the importance of the clinical bedside examination in assessing dysphagia in pediatric patients post-TBI for identifying targets for intervention.

Expanded understanding of the trends and determinants of food consumption is needed to reduce the ecological impacts of the contemporary agro-food system while also being attentive to broader issues pertaining to health and the environment. Incorporating these additional aspects and formulating meaningful dietary recommendations is a major challenge. This article seeks to highlight differences in ecological footprint (EF) by activity level for various so-cial groups to meet suggested physiological requirements by nutritionists versus actual food consumption. The study is based on a combination of healthy diet requirements (as expressed by national guidelines) and a survey of a repre-sentative sample of 1,013 Hungarian adults using a bottom-up approach for calculating EFs. Students and women with small children have a higher than average food-related EF due to their higher nutritional needs. At the same time, the elderly are characterized by lower footprints. Perhaps most interesting is our finding that people with seden-tary forms of employment have higher food footprints than those with jobs that require physical labor. We offer rec-ommendations for food-policy planning based on encouraging dietary changes for individuals, differentiated by the nature of their work. The research suggests that dietary policy that improves health often has environmental benefits.

Background: Arterial pulse pressure, the difference between systolic and diastolic blood pressure, has been used as an indicator (surrogate measure) of arterial stiffness. High arterial pulse pressure (> 40) has been associated with increased cardiovascular disease and mortality. Several clinical trials have reported that the proportion of calories from carbohydrate has an effect on blood pressure. The primary objective of this study was to assess arterial pulse pressure and its association with carbohydrate quantity and quality (glycemic load) with diabetes status for a Cuban American population. Methods: A single point analysis included 367 participants. There was complete data for 365 (190 with and 175 without type 2 diabetes). The study was conducted in the investigator’s laboratory located in Miami, Florida. Demographic, dietary, anthropometric and laboratory data were collected. Arterial pulse pressure was calculated by the formula systolic minus the diastolic blood pressure. Glycemic load, fructose, sucrose, percent of average daily calories from carbohydrate, fat and protein, grams of fiber and micronutrient intakes were calculated from a validated food frequency questionnaire. Results: The mean arterial pulse pressure was significantly higher in participants with (52.9 ± 12.4) than without (48.6 ± 13.4) type 2 diabetes. The odds of persons with diabetes having high arterial pulse pressure (>40) was 1.85 (95% CI =1.09, 3.13); p=0.023. For persons with type 2 diabetes higher glycemic load was associated with lower arterial pulse pressure. Conclusions: Arterial pulse pressure and diet are modifiable risk factors of cardiovascular disease. Arterial pulse pressure may be associated with carbohydrate intake differently considering diabetes status. Results may be due to individuals with diabetes following dietary recommendations. The findings of this study suggest clinicians take into consideration how medical condition, ethnicity and diet are associated with arterial pulse pressure before developing a medical nutrition therapy plan in collaboration with the client.

Background: Research indicates that a diet rich in whole grains may reduce the risk of prevalent chronic diseases, including cardiovascular disease, diabetes, and some cancers, and that risk for these diseases varies by ethnicity. The objective of the current study was to identify major dietary sources of grains and describe their contribution to B vitamins in five ethnic groups. Methods. A cross-sectional mail survey was used to collect data from participants in the Multiethnic Cohort Study in Hawaii and Los Angeles County, United States, from 1993 to 1996. Dietary intake data collected using a quantitative food frequency questionnaire was available for 186,916 participants representing five ethnic groups (African American, Latino, Japanese American, Native Hawaiian and Caucasian) aged 45-75 years. The top sources of grain foods were determined, and their contribution to thiamin, riboflavin, niacin, vitamin B6, and folic acid intakes were analyzed. Results: The top source of whole grains was whole wheat/rye bread for all ethnic-sex groups, followed by popcorn and cooked cereals, except for Native Hawaiian men and Japanese Americans, for whom brown/wild rice was the second top source; major contributors of refined grains were white rice and white bread, except for Latinos. Refined grain foods contributed more to grain consumption (27.1-55.6%) than whole grain foods (7.4-30.8%) among all ethnic-sex groups, except African American women. Grain foods made an important contribution to the intakes of thiamin (30.2-45.9%), riboflavin (23.1-29.2%), niacin (27.1-35.8%), vitamin B6 (22.9-27.5%), and folic acid (23.3-27.7%). Conclusions: This is the first study to document consumption of different grain sources and their contribution to B vitamins in five ethnic groups in the U.S. Findings can be used to assess unhealthful food choices, to guide dietary recommendations, and to help reduce risk of chronic diseases in these populations.

UNLABELLED: Understanding associations between food preferences and weight loss during various effective diets could inform efforts to personalize dietary recommendations and provide insight into weight loss mechanisms. We conducted a secondary analysis of data from a clinical trial in which participants were randomized to either a 'choice' arm, in which they were allowed to select between a low-fat diet (n = 44) or low-carbohydrate diet (n = 61), or to a 'no choice' arm, in which they were randomly assigned to a low-fat diet (n = 49) or low-carbohydrate diet (n = 53). All participants were provided 48 weeks of lifestyle counseling. Food preferences were measured at baseline and every 12 weeks thereafter with the Geiselman Food Preference Questionnaire. Participants were 73% male and 51% African American, with a mean age of 55. Baseline food preferences, including congruency of food preferences with diet, were not associated with weight outcomes. In the low-fat diet group, no associations were found between changes in food preferences and weight over time. In the low-carbohydrate diet group, increased preference for low-carbohydrate diet congruent foods from baseline to 12 weeks was associated with weight loss from 12 to 24 weeks. Additionally, weight loss from baseline to 12 weeks was associated with increased preference for low-carbohydrate diet congruent foods from 12 to 24 weeks. Results suggest that basing selection of low-carbohydrate diet or low-fat diet on food preferences is unlikely to influence weight loss. Congruency of food preferences and weight loss may influence each other early during a low-carbohydrate diet but not low-fat diet, possibly due to different features of these diets. CLINICAL TRIAL REGISTRY: NCT01152359.

SACN reviewed the evidence on vitamin D and health to see if UK dietary recommendations, set in 1991, were still appropriate. In addition to the main report, you can read the SACN press release. In a change to previous advice, SACN is now recommending: a reference nutrient intake (RNI) of 10 micrograms of vitamin D per day, throughout the year, for everyone in the general population aged 4 years and older an RNI of 10 micrograms of vitamin D per day for pregnant and lactating women and population groups at increased risk of vitamin D deficiency a ‘safe intake’ of 8.5 to 10 micrograms per day for all infants from birth to 1 year of age a ‘safe intake’ of 10 micrograms per day for children aged 1 to 4 years The RNI and safe intakes were developed to ensure that the majority of the UK population has enough vitamin D to protect musculoskeletal health, all year round. SACN did not take account of sunlight exposure in making recommendations because of the number and complexity of factors that affect skin synthesis of vitamin D. The RNI and safe intakes refer to intake from all dietary sources: natural food sources fortified foods (including infant formula milk) supplements They also refer to average intakes over a period of time, such as a week, and take account of day-to-day variations in intake.

The impact of cooking methods (industrial pre-frying, deep-fat frying and baking) on the nutritional quality and safety of chicken breaded nugget samples from supermarket and commercial brands was evaluated. The changes in the quality characteristics (nutritional composition, fatty acids profile, cholesterol and salt) of the fried food and frying oil, after ten consecutive frying operations, were evaluated. The total fat content of nuggets varied between 10.9 and 22.7 g per 100 g of edible portion and the salt content ranged from 0.873 to 1.63 g per 100 g. Taking into account one portion of nuggets, the daily intake of salt can reach 49%, which can have a significant impact on the health of those who regularly consume this type of food, especially considering the prevalence of hypertension around the world. The analysed chicken breaded nuggets are rich in unsaturated fatty acids, which have been related with potential health benefits, namely regarding cardiovascular diseases. The cholesterol content of baked samples was two times higher when compared with the fried ones. The trans fatty acids and polar compounds contents of the frying oil used for frying significantly increased, but the values were still away from the maximum recommended by legal entities for its rejection. From a nutritional point of view, it is possible to conclude that the applied cooking methods can significantly influence the nutritional quality and safety of the analysed chicken breaded nuggets. This study will contribute to important knowledge on how the applied cooking methods can change the nutritional quality and safety of foods, namely of chicken nuggets, and can be very useful for dietary recommendations and nutritional assessment.

Objectives Maternal nutrition during pregnancy plays an important role in predisposing offspring to the development of chronic disease in adulthood, including osteoporosis. Our aim was to investigate maternal dietary intakes during pregnancy, with a focus on nutrients important for skeletal development in the offspring. Methods In this case-control study, cases were pregnant women recruited for the Vitamin D in Pregnancy Study (n = 350, age 20-40 years) and controls were non-pregnant peers participating in the Geelong Osteoporosis Study (n = 305, age 20-40 years). Dietary intakes of nutrients were quantified using a validated food frequency questionnaire. Results Compared to controls, cases consumed more energy [median (interquartile range): 7831 (6506-9461) vs. 7136 (6112-8785) kJ/day]; median intakes for cases were greater for carbohydrates [206.2 (172.5-249.9) vs. 188.2 (147.7-217.5) g/day], fat [77.9 (60.3-96.6) vs. 72.1 (53.3-87.4) g/day], potassium [2860 (2363-3442) vs. 2606 (2166-3442) mg/day] and calcium [1022 (819-1264) vs. 918 (782-1264) mg/day] (all p ≤ 0.05). However, pregnant women were not consuming greater amounts of those nutrients which had an increased demand (protein, magnesium, phosphorus and zinc). Similarly, this translated to the likelihood of achieving national recommendations for corresponding nutrients. Conclusions for Practice Compared to their non-pregnant peers, pregnant women were more likely to meet dietary recommendations for calcium and potassium; however, this was not the pattern observed for protein, magnesium and zinc. Future public health messages should perhaps focus on increasing awareness of the importance of all these nutrients during pregnancy.

BACKGROUND: Skipping breakfast is associated with poorer diet quality among adults, but evidence of associations for other eating patterns [e.g., eating occasion (EO), meal, or snack frequency] is equivocal. An understanding of how eating patterns are associated with diet quality is needed to inform population-level dietary recommendations. OBJECTIVE: We aimed in this cross-sectional study to determine the relation between frequency of meals, snacks, and all EOs with nutrient intakes and diet quality in a representative sample of Australian adults. METHODS: Dietary data for 5242 adults aged ≥19 y collected via two 24-h recalls during the 2011-2012 National Nutrition and Physical Activity Survey were analyzed. EO, meal, and snack frequency was calculated. Adherence to recommendations for healthy eating was assessed with the use of the 2013 Dietary Guidelines Index (DGI) and its subcomponents. Linear regression, adjusted for covariates and energy misreporting, was used to examine associations between eating patterns, energy-adjusted nutrient intakes, and the DGI-2013. RESULTS: The frequency of meals, but not of snacks, was positively associated with micronutrient intakes, overall diet quality [men: β = 5.6 (95% CI: 3.9, 7.3); women: β = 4.1 (95% CI: 2.2, 5.9); P < 0.001], and DGI-2013 component scores for cereals, lean meat and alternatives, and alcohol intake (P < 0.05). A higher frequency of all EOs, meals, and snacks was positively associated with DGI-2013 scores for food variety, fruits, and dairy foods (P < 0.05). Conversely, a higher snack frequency was associated with a lower compliance with guidelines for discretionary foods and added sugars among men (P < 0.05). CONCLUSIONS: These findings suggest that meal frequency is an important determinant of nutrient intakes and diet quality in Australian adults. Inconsistent associations for snack frequency suggest that the quality of snack choices is variable. More research examining the dietary profiles of eating patterns and their relations with diet quality is needed to inform the development of meal-based guidelines and messages that encourage healthy eating.

Aim: To examine the amount of money spent on food by household income, and to ascertain whether food expenditure mediates the relationship between household income and the purchase of staple foods consistent with Australian dietary guideline recommendations. ----- ----- Methods: In face-to-face interviews (n = 1003, 66.4% response rate), households in Brisbane, Australia were asked about their purchasing choices for a range of staple foods, including grocery items, fruits and vegetables. For each participant, information was obtained about their total weekly household food expenditure, along with their sociodemographic and household characteristics. ----- ----- Results: Household income was significantly associated with food expenditure; participants residing in higher-income households spent more money on food per household member than those from lower-income households. Lower income households were less likely to make food purchasing choices of dietary staples that were consistent with recommendations. However, food expenditure did not attenuate the relationship between household income and the purchase of staple foods consistent with dietary guideline recommendations. ----- ----- Conclusions: The findings suggest that food expenditure may not contribute to income inequalities in purchasing staple foods consistent with dietary guideline recommendations: instead, other material or psychosocial factors not considered in the current study may be more important determinants of these inequalities. Further research should examine whether expenditure on non-staple items and takeaway foods is a larger contributor to socioeconomic inequalities in dietary behavior.

Dietary intake and food habits are important contributors to the obesity epidemic. They are highly modifi able components of energy balance and are usually targeted in both obesity prevention and treatment programs. However, measurement of total diet creates challenges and can convey a large burden in terms of cost, technical expertise, impact on respondents and time. It is not surprising therefore that comprehensive reports of dietary intake in children are uncommon and, when reported, have limitations. The aim of this paper is to guide researchers and practitioners in selecting the most appropriate dietary assessment method for situations involving children and adolescents. This paper presents a summary of the issues to consider when choosing a method, a description of some of the more commonly used dietary assessment methods for young people and a series of case-studies to illustrate the range of circumstances faced when measuring dietary intake. We recommend that researchers consider the specifi c components of dietary intake addressed in their research and practice, and whether diet should be reported comprehensively or as targeted components. Other considerations include age, cognitive ability, weight status, physical activity level, respondent burden, and reliability and validity in the context of program goals and research questions. A checklist for selecting the appropriate dietary methodology is provided. This guide aims to facilitate the reporting of dietary intake and food habits in the context of obesity using valid and reliable measures, thus contributing to the evidence-base for nutrition policies and programs relating to obesity.

Background/Objectives: The main objective of European Food Consumption Validation (EFCOVAL)-child Project is to define and evaluate a trans-European methodology for undertaking national representative dietary surveys among children in the age group of 4–14 years. In the process of identifying the best dietary assessment methodologies, experts were brought together at a workshop. The paper presents the discussion of the best available method and the final recommendations for a trans-European dietary assessment method among 4- to 14-year-old children.
Subjects/Methods: The starting point was to investigate whether the method (two non-consecutive 24-h dietary recalls (24-HDRs)) suggested for the adults in European Food Consumption Survey Method (EFCOSUM) would be usable for children in
the age group between 4 and 14 years. However, all available dietary assessment methods were included in the discussion to ensure that the final recommendation would be based on the best evidence. Six criteria were defined and used as additional
guidance in the process.
Results: The literature does not give a clear recommendation on the dietary assessment methods that are most suitable for children in the age group of 4–14 years. Nevertheless, on the basis of the literature, the recommendations were separated for preschoolers (4–6 years) and schoolchildren (7–14 years).
Conclusion: For preschoolers, two non-consecutive days of a structured food record are recommended, using a (for children adapted) picture booklet and household measures for portion-size estimation. For schoolchildren, repeated 24-HDRs are recommended, using a picture booklet and household measures for portion-size estimation. In addition, the child should bring a booklet to register what is eaten out of home. One parent should assist the schoolchild at the 24-HDR interview, and therefore face-to-face interviews are required.
