The food exchange list (FEL) is a tool for planning meals using a list of foods grouped with approximately the same amount of energy and macronutrients. The Philippine FEL underwent three revisions from its publication in 1953 until 1994. This most recent revision of the FEL aimed to review calculations of macronutrient and energy content per exchange and by food group, review the methods of dietary calculation, and enhance the design and appearance of the handbook. Revision of the handbook started with needs assessment using a survey as study design among 529 registered nutritionist-dietitians (RNDs) and nutrition students, and focus group discussion (FGD) among 36 selected hospital nutrition supervisors, nutrition faculty, and health workers in three cities of the Philippines -- namely, Manila, Cebu, and Davao. The seven food groups in the previous FEL editions were adopted as the main components of foods for substitution. Macronutrient content per exchange was computed from the 2017 Philippine food composition tables (FCTs) and foreign food databases. Results of the survey revealed that most RNDs used the FEL in a clinical or hospital setting (98.1%), while students used the FEL for themselves (93.8%). The FEL was mainly used for meal planning (87.5%), as reference (62.8%), and for counseling (48.4%). Almost all respondents described the FEL as very useful. The addition of more foods available in the market was the most common suggestion of respondents. Based on the suggestions from the survey and FGD the following changes were made: recomputed and reclassified 525 food items within the seven food groups and subgroups; reclassified rice group into low-, medium-, and high-protein subgroups; the alphabetical arrangement of foods with Filipino common names and English names; additional equations for deriving desirable body weight (DBW) and total energy requirement (TER); and included photos of selected foods per exchange. Improvement of the design and appearance of the handbook was accomplished through the use of color-coding, food photos, and a tabulated food listing. [ABSTRACT FROM AUTHOR]

Growing older in rural areas can be challenging since access to support from others can be difficult. I conducted an exploratory descriptive study, framed by exchange theory, in rural Appalachian North Carolina in the United States over the course of a year with 16 rural elders with physical limitations and 8 of their supporters to determine how and why they constructed their networks of support. I conducted a total of 50 interviews. Through the analysis of interview data a theme regarding the important role of the exchange of food emerged. For this group of rural elders, food is both given to and received from others. The giving of food to others helps to rebalance exchanges where elders are receiving a good deal of support. In addition, food is exchanged for reasons that move well beyond nutritional needs. Food is used to initiate and support social exchanges, as expressions of kindness and neighborliness, and as a way to share abundance. Results expand on our understanding of the role of food exchanges in the lives of rural elders and expand exchange theory to include the motivations behind exchanges as an additional component of the theory.

This review focuses at highlighting the importance of Food Exchange List in cultural perspective, as an effective dietary tool to help individuals' manage their dietary modifications in relation to non communicable diseases whilst specifying measures that can help improve the quality of Food Exchange Lists for combating various non communicable diseases and addressing adherence related issues to specialized diets. A search was done using PubMed & Google Scholar till June 2016. Search terms used were food exchange list AND disease, diet AND non-communicable diseases. We included only studies that discussed Food Exchange List (FEL) in relation to non-communicable diseases; in addition to factors like cultural relevance and adherence. Out of the 837 papers accessed 57 were identified as relevant to the Food Exchange List, out of which 39 papers were focused to the concept and development of the Food Exchange List. Only 18 discussed FEL in relation to non communicable diseases and were thus included in the review. Food exchange list is a user friendly tool for dietary modification due to disease. This tool may help to customize meals for people as it provides information regarding various food items in different groups. This tool is helpful in reducing blood & plasma glucose levels, maintaining lipid profile & effectively combating other diet related diseases & those ailments in which diet plays a significant role in maintenance & prevention from reoccurrences. However, better management and adherence to modified diets for non communicable diseases can be ensured by keeping cultural relevance under consideration before using Food Exchange Lists for such diseases.

BackgroundFood exchange lists are one of the main methods of nutritional education. However, Korean food exchange lists have not been revised since 1994. Therefore, we surveyed the opinions of diabetes educators and patients with diabetes regarding the need for revision of the current food exchange lists.MethodsFor two weeks beginning on 10 March 2008, a 12-item questionnaire regarding the opinion and need for revision of the current food exchange lists was e-mailed to diabetes educators nationwide. Another 15-question survey was administered to patients with diabetes in 13 hospitals located in the Seoul and Gyeonggi regions of Korea.ResultsWe obtained survey responses from 101 diabetes educators and 209 patients; 65 (64.3%) of the educators answered that the current food exchange lists should be revised. The items that needed revision were the glycemic index, addition of new foods and reaffirmation of exchange standard amounts. The patients demanded specific education about choosing appropriate foods, a balanced meal plan, proper snacks, and dining intake.ConclusionOur survey results demonstrate the need to revise the Korean food exchange lists. This process should focus on glycemic index, the addition of new foods and reconfirmation of one exchange reference unit.

We examine the cultural context of food insecurity among Inuit in Ulukhaktok, Northwest Territories, Canada. An analysis of the social network of country food exchanges among 122 households in the settlement reveals that a household’s betweenness centrality—a measure of brokerage—in the country food network is predicted by the age of the household. The households of married couples were better positioned within the sharing network than were the households of single females or single males. Households with an active hunter or elder were also better positioned in the network. The households of single men and women appear to experience limited access to country food, a considerable problem given the increasing number of single-adult households over time. We conclude that the differences between how single women and single men experience constrained access to country foods may partially account for previous findings that single women in arctic settlements appear to be at particular risk for food insecurity.

The anemone-anemonefish association is the quintessential symbol of a symbiotic mutualism from the Indo-Pacific waters. Both historical field documentation and extant scientific research advocate that these interactions are fundamental at the level of nutrient exchanges and evolutionary driving forces (natural selection) to facilitate this mutualism. Through the use of N and C stable isotope tracers, complementary laboratory- and field-based experiments were implemented in the Philippines to investigate the possibility of nutrient transmission from the host anemone, Heteractis crispa and/or endosymbiotic zooxanthellae, to two species of exosymbiotic anemonefishes ( Amphiprion clarkii and A. perideraion). Mass spectrometry analyses suggest that N and C concentrations were significantly higher in tissues of the anemonefishes (intestines, liver, gills, and gonads), anemone host, and zooxanthellae compared with controls. We interpret the presence of N and C in the anemonefish tissues as direct empirical evidence for the transmission of nitrogen and/or carbon from host anemone and endosymbiotic zooxanthellae to resident anemonefish. These 'translocations' and resultant recycling of elements within this classical tripartite relationship highlight the fundamental role of nutrient dynamics in this synergistic symbiosis.

The Department of Agriculture's MyPyramid is presented as food guidance for the US general public and not "a therapeutic diet for any specific health condition," although many adults in this country are overweight or obese and many experience diet-related disorders. This paper shows the recommendations in MyPyramid are remarkably consistent with the various recommendations to control obesity and diabetes, heart disease and stroke, hypertension, cancer, and osteoporosis. Specifically, the food intake recommendations are similar to those recommended by the Dietary Approaches to Stop Hypertension Eating Plan, the American Heart Association, and the American Cancer Society; plus, the calculated nutrient intakes associated with following the guide are generally within the ranges of nutrient recommendations from the Clinical Guidelines on Overweight and Obesity, the American Diabetes Association, the National Cholesterol Education Program, the American Heart Association, the National Committee on High Blood Pressure, and the American Institute for Cancer Research. However, for actual nutrient levels to conform to dietary guidance, key assumptions regarding how closely individuals will follow the MyPyramid patterns must be made: an appropriate energy level must be selected and adhered to, and an appropriate profile of foods must be selected. These issues must be understood by food and nutrition professionals and disseminated to the public for MyPyramid to reach its potential.

Pastries and desserts that is an important place in Turkish cuisine have variety too much according to the designs and cooking materials. This research planned and carried out (1) to analyze the amount of protein, fat, moisture and ash and determine to energy values; (2) to determine the places of in the food change lists of the some bakery products consumed by Turkish people frequently. To this purpose, this research was conducted on total 89 pieces consisting of the salty dry pastries, sweet dry pastries, patty, cake and desserts whose production is in the 4 large patisseries located in Ankara. Functional product development efforts in collaboration with food industry and health care professionals should be done related to compositions of these kind products in order to make to bring them healthier.

Objective: Determine the effects of a short-term, multi-faceted, point-of-selection intervention on college students’ perceptions and selection of 10 targeted healthful foods in a university dining hall and changes in their self-reported overall eating behaviors. Participants: 104 college students, (age 18–23) completed pre-I and post-I surveys. Methods: Pre-survey collected at dining hall in April 2007, followed by 3-week intervention then post-survey collected via email. Healthy choice indicators, large signs, table tents, flyers and colorful photographs with “benefit-based messages” promoted targeted foods. Response rate to both surveys was 38%. Results: Significantly more participants reported that healthful choices were clearly identified in the dining hall after the intervention. Over 20% of participants reported becoming more aware of healthful food choices in the dining hall after the intervention. Significant increases in self-reported intake were reported for cottage cheese and low-fat salad dressing, with a trend toward increased consumption of fresh fruit. Seven of the 14 assessed eating behaviors had significant changes in the desired direction. Increased awareness of healthful foods was the top reason for self-reported changes in overall eating behaviors. Conclusion: Short-term, multi-faceted, point-of-selection marketing of healthful foods in university dining halls may be beneficial for improving college students’ perceptions and selections of targeted healthful foods in the dining hall and may improve overall eating behaviors of college students.

The article discusses the diabetes exchange list and the carbohydrate counting. It mentions that carbohydrate plays a significant role in an individual's nutritional needs as it is the body's number one fuel base. It cites the two types of carbohydrates which is the simple and complex or the ones known as starches. It notes that a diabetic diet should set the carbohydrate level at about 50 percent of a person's estimated caloric needs.

Mathematical diet optimization models are used to create food plans that best resemble current eating habits while meeting prespecified nutrition and cost constraints. This study used linear programming to generate food plans meeting the key 2007 dietary recommendations issued by the World Cancer Research Fund/American Institute of Cancer Research (WCRF/AICR). The models were constructed to minimize deviations in food intake between the observed and the WCRF/AICR-recommended diets. Consumption constraints were imposed to prevent food plans from including unreasonable amounts of food from a single group. Consumption norms for nutrients and food groups were taken from dietary intake data for a sample of adult men and women (n = 1611 in the Pacific Northwest. Food plans meeting the WCRF/AICR dietary guidelines numbers 3-5 and 7 were lower in refined grains and higher in vegetables and fruits than the existing diets. For this group, achieving cancer prevention goals required little modification of existing diets and had minimal impact on diet quality and cost. By contrast, the need to meet all nutritional needs through diet alone (guideline no. 81 required a large food volume increase and dramatic shifts from the observed food intake patterns. Putting dietary guidelines into practice may require the creation of detailed food plans that are sensitive to existing consumption patterns and food costs. Optimization models provide an elegant mathematical solution that can help determine whether sets of dietary guidelines are achievable by diverse U.S. population subgroups. [ABSTRACT FROM AUTHOR]

Our objective in this study was to develop and implement an effective intervention strategy to manipulate the amount and composition of dietary fat and carbohydrate (CHO) in free-living individuals in the RISCK study. The study was a randomized, controlled dietary intervention study that was conducted in 720 participants identified as higher risk for or with metabolic syndrome. All followed a 4-wk run-in reference diet [high saturated fatty acids (SF)/high glycemic index (Gl)[. Volunteers were randomized to continue this diet for a further 24 wk or to 1 of 4 isoenergetic prescriptions [high monounsaturated fatty acids (MUFA)/high GI; high MUFA/Iow GI; low fat (LF)/high GI; and LF/low GI]. We developed a food exchange model to implement each diet. Dietary records and plasma phospholipid fatty acids were used to assess the effectiveness of the intervention strategy. Reported fat intake from the LF diets was significantly reduced to 28% of energy 1% E) compared with 38% E from the HM and LF diets. SF intake was successfully decreased in the HM and LF diets to ≤10% E compared with 17% E in the reference diet (P= 0.001). Dietary MUFA in the HM diets was ∼17% E, significantly higher than in the reference (12%E) and LF diets (10%E) (P = 0.001). Changes in plasma phospholipid fatty acids provided further evidence for the successful manipulation of fat intake. The GI of the HGI and LGI arms differed by ∼9 points (P = 0.001). The food exchange model provided an effective dietary strategy for the design and implementation across multiple sites of 5 experimental diets with specific targets for the proportion of fat and CHO.

This article reports on a contestation around the meaning of 'local food', between a group engaged in 'alternativizing' food exchanges building on a vision of cooperative knowledge-sharing and opportunity-sharing, and one engaged in 'reform' of the conventional system. The latter envisions the formation of individual entrepreneurs and a top-down provision of commercial and production knowledges, emphasizing 'innovation' in food products as the way to gain access to the global system. The contestation is ongoing in a single space, where the two visions of advancing the local food project coexist and are found within separate but overlapping networks. The paper suggests that the struggle between them is not only over strategies to improve economic returns to such producers, but also over the social forms and relations of production seen as appropriate for 'rural development' in the Irish context. The 'ambiguities' of the relations of power across space, while not affecting the market discourse of local food, work to disorganise and destablise relations within the alternative network and to make the project of an alternative local food system vulnerable to transition into forms more compatible with capitalist development policy.

Aims: The aim of this study is to compare the efficacy of low glycaemic index (GI) vs. conventional carbohydrate exchange (CCE) dietary advice on glycaemic control and metabolic parameters in patients with type 2 diabetes. Methods: A total of 104 patients with type 2 diabetes were randomly assigned to either a low GI (GI) or CCE dietary advice over a 12-week period. The primary end-point was glycaemic control as assessed by glycated haemoglobin A1c (HbA1c), fructosamine level and plasma glucose. The secondary end-points were anthropometric measurements and metabolic parameters that include blood pressure, lipid profile and insulin levels. The oral antidiabetic medications remained unchanged throughout the duration of the study. Results: A low-GI diet was associated with significant changes in the fructosamine level (ΔGI = −0.20 ± 0.03; ΔCCE = −0.08 ± 0.03 mmol/l, p < 0.01) and waist circumference (ΔGI group = −1.88 ± 0.30 cm; ΔCCE group: −0.36 ± 0.4 cm, p < 0.05) at week 4. At week 12, the changes in fasting glucose (ΔGI = −0.03 ± 0.3; ΔCCE = 0.7 ± 0.3 mmol/l; p < 0.05) and waist circumference (ΔGI = −2.35 ± 0.47 cm; ΔCCE group = −0.66 ± 0.46 cm; p < 0.05) in the GI group was significantly lower than the CCE group. With the low-GI diet, the changes in postprandial glycaemia at time 0, 60, 150 and 180 min after consuming the standard test meal was lower than with the CCE diet (p < 0.05). No significant differences were found between the groups for the remaining parameters that were measured. Conclusions: Use of a low-GI diet resulted in significant changes of serum fructosamine level, plasma glucose and waist circumference in Asian patients with type 2 diabetes over a 12-week period compared with those following a CCE diet. The effect on HbA1c and other metabolic parameters was not significantly different between the two study groups but the improvement within the GI group was more pronounced and of clinical benefit.

Objective: To develop exchange lists for the assessment of food and nutrient intakes for people with diabetes in Mali. Design: Based on North American exchange lists, a Malian food exchange system was developed using food composition tables for Mali. Dietary intakes were assessed by two 48-hour dietary recalls. Daily numbers of exchanges were determined for the whole sample and for each gender. Energy and macronutrient intakes obtained by a software-based nutritional analysis of the dietary recalls were compared with the average energy and nutrient values calculated with the exchange lists. Setting: Centre National de Lutte contre le Diabète. Subjects: Seventeen male and 40 female adults with type 2 diabetes. Results: The analysis of food recalls using the Malian exchange system showed that subjects consumed the following numbers of exchanges per day: 2.6 ± 1.5 meat and substitutes, 0.5 ± 0.8 legumes, 0.7 ± 1.2 milk, 8.0 ± 4.1 fat, 8.3 ± 3.0 starch, 1.5 ± 0.9 vegetables, 0.2 ± 0.5 fruit, and 0.0 ± 0.2 sugar-added foods, totalling 1 854 ± 648 kcal, 260 ± 92 g carbohydrate, 56 ± 23 g protein and 63 ± 31 g fat. These results concerning energy and macronutrients did not differ significantly from those obtained from the nutritional analysis of food recalls with software using data from the Food Composition Table for Mali. Compared to women, men consumed significantly larger numbers of exchanges of meat and substitutes, fat, starch, and fruit. No significant differences were found for the intakes of legumes, milk, vegetables and sugar-added foods. Conclusions: This study allowed the development of Malian food exchange lists and demonstrated their usefulness for the description of the dietary pattern and energy and macronutrient intakes of male and female Malian type 2 diabetic patients.

Aim: The present study was conducted to develop a meal-planning exchange list for Middle Eastern foods commonly included in the Jordanian cuisine. Methods: Forty types of appetisers and another 40 types of desserts were selected, with five different recipes for each item. Recipes were collected from different housewives and Arabic cookbooks. Ingredients’ weight and dish net weight were recorded based on an average recipe, and dishes were prepared accordingly. Dishes were proximately analysed following the Association of Official Analytical Chemists procedures. Proximate analysis was compared with the World Health Organisation Food Composition Tables for the Use in the Middle East, and with food analysis software (ESHA). Results: Significant correlations ( P < 0.001) were found between macronutrient content obtained from proximate analysis and those obtained from ESHA. The correlation coefficients (r) were 0.92 for carbohydrate, 0.86 for protein and 0.86 for fat. Strong correlations were also detected between proximate analysis World Health Organisation food composition tables for carbohydrate (r = 0.91, P < 0.001) and protein (r = 0.81; P < 0.001) contents. However, this significant correlation was not found as strong, yet significant for fat (r = 0. 62, P < 0.001). Conclusion: A valid exchange system for traditional desserts and appetisers is now available and ready to be used by dietitians and health-care providers in Jordan and Arab World.

In this article, an instrument is presented to diagnose microbial safety control activities in a food safety management system. The need of such a tool is derived from the importance of microbial safety control and the need for improvement of existing control systems. Careful diagnosis of these systems provides the basis for their improvement. The diagnostic instrument provides a comprehensive checklist of crucial control activities, addressing major technology-dependent and managerial activities in design and operation of preventive measures, intervention processes, and monitoring systems. Secondly, it provides detailed grids describing three levels of execution for each safety control activity to enable a differentiated assessment of ones food safety control system situation. The basic assumption underlying the diagnostic instrument is that activities on a higher level are more predictable and better able to achieve a desired safety outcome, due to more insight in underlying mechanisms and more accurate information. Finally, we discuss that using the instrument may contribute in finding effective types and levels of control activities within given contextual dependencies. [Copyright &y& Elsevier]

Reciprocity and redistribution economies are often used by low-income households to increase access to food, adequate diets, and food security. A United States study of two high poverty rural counties and two low-income urban neighborhoods reveal poor urban households are more likely to access food through the redistribution economy than poor rural households. Reciprocal nonmarket food exchanges occur more frequently in low-income rural households studied compared to low-income urban ones. The rural low-income purposeful sample was significantly more likely to give food to family, friends, and neighbors and obtain food such as fish, meat, and garden produce from friends and family compared to the urban low-income group. Further, 58% of the low-income rural group had access to garden produce while only 23% of the low-income urban group reported access. In a rural random sample of the whole population in the two high poverty counties access to garden produce increased chances of attaining recommended vegetable and fruit servings controlling for income, education, and age. Access to a garden also significantly increased the variety of fruits and vegetables in diets. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Our objectives in this study were to expand a previously reported U.S. market basket survey using a larger sample size and to estimate levels of PBDE intake from food for the U.S. general population by sex and age. METHODS: We measured concentrations of 13 polybrominated diphenyl ether (PBDE) congeners in food in 62 food samples. In addition, we estimated levels of PBDE intake from food for the U.S. general population by age (birth through ≥ 60 years of age) and sex. RESULTS: In food samples, concentrations of total PBDEs varied from 7.9 pg/g (parts per trillion) in milk to 3,726 pg/g in canned sardines. Fish were highest in PBDEs (mean, 1,120 pg/g; median, 616 pg/g; range, 11.14–3,726 pg/g). This was followed by meat (mean, 383 pg/g; median, 190 pg/g; range, 39–1,426 pg/g) and dairy products (mean, 116 pg/g; median, 32.2 pg/g; range, 7.9–683 pg/g). However, using estimates for food consumption (excluding nursing infants), meat accounted for the highest U.S. dietary PBDE intake, followed by dairy and fish, with almost equal contributions. Adult females had lower dietary intake of PBDEs than did adult males, based on body weight. We estimated PBDE intake from food to be 307 ng/kg/day for nursing infants and from 2 ng/kg/day at 2–5 years of age for both males and females to 0.9 ng/kg/day in adult females. CONCLUSION: Dietary exposure alone does not appear to account for the very high body burdens measured. The indoor environment (dust, air) may play an important role in PBDE body burdens in addition to food. [ABSTRACT FROM AUTHOR]

Humans harbor a consortium of commensal bacteria in their gut that are thought to be crucial for normal health. However, the extent of microbial diversity in the gut and the physiologic functions of the microflora have not yet been fully characterized. Molecular tools are now available to characterize the associations between diet, microflora composition, and health in greater depth. New molecular studies have confirmed earlier culture-based observations that diet has a role in the regulation of microflora composition. In the near future, new insight into these associations should allow for the design of specific diets aimed at improving health by modulating microflora. [ABSTRACT FROM AUTHOR]
