Dietary recommendations comparing Dietary Guidelines from brazil and the united states
Cadernos De Saude Publica, 2010Co-Authors: Rosely Sichieri, Stephanie E Chiuve, Rosângela Alves Pereira, Aline Cristine Souza Lopes, Walter C WillettAbstract:The Brazilian Dietary Guidelines are based in part on mainstream United States' recommendations, in spite of the criticisms and shortcomings of the American Guidelines. In this paper, Brazilian food Guidelines are summarized and discussed in comparison with the USA recommendations. American and Brazilian Dietary recommendations are quite similar in many aspects, particularly those related to variety in the diet, the importance of physical activity and weight management. Different to American Guidelines, those from Brazil advise people to choose fresh foods, to prefer healthier types of fat, to limit trans fat intake and to eat good sources of protein, but does not recommend the consumption of whole grains. Besides the challenges related to their implementation, indicators for the evaluation of the effectiveness of these Guidelines should be established from the beginning, particularly those related to changes in Dietary habits and the prevalence of obesity.

Dietary pattern analysis for the evaluation of Dietary Guidelines
Asia Pacific Journal of Clinical Nutrition, 2008Co-Authors: Walter C Willett, Marjorie L McculloughAbstract:Dietary Guidelines for the promotion of overall good health and the prevention of disease often play an important role in setting nutritional policy and in the education of the public about healthy food choices. Although much has been written about adherence to such Guidelines, until recently there was no evidence on whether adherence to specific Dietary Guidelines is associated with better health. As an outcome variable for such analyses, we have used the incidence of major chronic disease, which includes incidence of any major cardiovascular disease, cancer, or death from any cause excluding violence. We have evaluated the Dietary Guidelines for Americans using a scoring system called the Healthy Eating Index developed by the Department of Agriculture to quantify adherence to these Guidelines. We found that adherence to the Dietary Guidelines and the Food Guide Pyramid was associated with only a small reduction in major chronic disease risk in a population of over 100,000 US adult men and women. We also assessed whether an alternate index, which took into account the type of fat and quality of carbohydrate, would better predict risk. In contrast with the original Healthy Eating Index, adherence to the alternative index predicted lower rates of major chronic disease, and particularly cardiovascular disease, suggesting that the Dietary Guidelines were not offering optimal Dietary guidance. These analyses suggest that Dietary Guidelines should be evaluated for their ability to predict the occurrence of major illness, and that such analyses can help refine these Guidelines.

overall adherence to the Dietary Guidelines for americans is associated with reduced prevalence of early age related nuclear lens opacities in women
Journal of Nutrition, 2004Co-Authors: Suzen M Moeller, Walter C Willett, Marjorie L Mccullough, Katherine L Tucker, Allen Taylor, Leo T Chylack, Susan E Hankinson, Paul F JacquesAbstract:Few studies have examined the efficacy of the Dietary Guidelines for Americans in the prevention of age-related chronic disease, such as age-related cataract. We examined whether adherence to the Guidelines was associated with a lower prevalence of age-related nuclear lens opacities in women. Eye exams were conducted in 479 Nurses' Health Study participants aged 52 to 73 y without previously diagnosed cataract or diabetes living in the Boston, MA area. Four FFQs, collected during a 9- to 11-y period before evaluation of lens status, were used to define diet quality according to the following: 1) daily number of servings of fruits, vegetables, and whole grains; 2) Recommended Foods Score (RFS); and 3) Healthy Eating Index (HEI). Nuclear opacities were defined as scores >/= 2.5 using the Lens Opacification Classification System III. After adjusting for age, smoking, and other risk factors, women in the highest quartile category of HEI scores were significantly less likely to have nuclear opacities than those in the lowest category [odds ratio (OR) = 0.47; 95% CI: 0.26-0.84]. This association appeared to be stronger among nonusers of supplemental vitamin C (OR = 0.23; 95% CI: 0.10-0.52). Decreased prevalence odds of nuclear opacities were also observed with high intake of fruit (OR = 0.58; 95% CI: 0.32-1.05) and whole grains (OR = 0.64; 95% CI: 0.36-1.15). These results suggest that overall compliance with the Dietary Guidelines, as measured by the HEI, protects against nuclear opacities.

endothelial function arterial stiffness and adherence to the 2010 Dietary Guidelines for americans a cross sectional analysis
British Journal of Nutrition, 2015Co-Authors: Katherine A Sauder, Lisa M Troy, Paul F Jacques, David N Proctor, Mosuk Chow, Na Wang, Joseph A Vita, Ramachandran S Vasan, Gary F Mitchell, Naomi M HamburgAbstract:Endothelial dysfunction and arterial stiffness are early predictors of CVD. Intervention studies have suggested that diet is related to vascular health, but most prior studies have tested individual foods or nutrients and relied on small samples of younger adults. The purpose of the present study was to examine the relationships between adherence to the 2010 Dietary Guidelines for Americans and vascular health in a large cross-sectional analysis. In 5887 adults in the Framingham Heart Study Offspring and Third Generation cohorts, diet quality was quantified with the 2010 Dietary Guidelines Adherence Index (DGAI-2010). Endothelial function was assessed via brachial artery ultrasound and arterial stiffness via arterial tonometry. In age-, sex- and cohort-adjusted analyses, a higher DGAI-2010 score (greater adherence) was modestly associated with a lower resting flow velocity, hyperaemic response, mean arterial pressure, carotid-femoral pulse wave velocity (PWV), and augmentation index, but not associated with resting arterial diameter or flow-mediated dilation (FMD). In multivariable models adjusting for cardiovascular risk factors, only the association of a higher DGAI-2010 score with a lower baseline flow velocity and augmentation index persisted (β = - 0·002, P= 0·003 and β = - 0·05 ± 0·02, P< 0·001, respectively). Age-stratified multivariate-adjusted analyses suggested that the relationship of higher DGAI-2010 scores with lower mean arterial pressure, PWV and augmentation index was more pronounced among adults younger than 50 years. Better adherence to the 2010 Dietary Guidelines for Americans, particularly in younger adults, is associated with a lower peripheral blood flow velocity and arterial wave reflection, but not FMD. The present results suggest a link between adherence to the Dietary Guidelines and favourable vascular health.

overcoming the challenges of translating the us Dietary Guidelines into healthier grain based foods
Nutrition Today, 2013Co-Authors: Paul F Jacques, Denise Hauge, Katherine Voth, Mindy Hermann, Beth Maschoff, Len MarquartAbstract:How can we translate the 2010 US Dietary Guidelines for Americans recommendations into grain-based foods that are more nutrient-rich, less calorie-dense, and more widely available to consumers? Grain-based foods are highly consumed and have the opportunity to be modified to provide healthier attributes. All segments of the food delivery system, from science (theory) to consumers (practice), need to work together in an integrated and multifaceted process that delivers grain-based foods richer in whole grain and fiber with smaller portion sizes and less solid fat, added sugars, and sodium, while still having a desirable taste profile and being accessible to the end consumer. Agradual shift in the amount of these ingredient/ nutrient categories could be achieved by setting incremental goals through collective knowledge, targeted research, policy recommendations, and a supportive regulatory environment. A greater abundance of accessible, healthier foods in targeted food environments, in unison with nutrition education, may be a more realistic approach for helping consumers come closer to meeting Dietary guidance. 1

the 2005 Dietary Guidelines for americans and risk of the metabolic syndrome
The American Journal of Clinical Nutrition, 2007Co-Authors: Jeanene J Foglicawley, Johanna T Dwyer, Marjorie L Mccullough, Edward Saltzman, Lisa M Troy, James B Meigs, Paul F JacquesAbstract:Background: The 2005 Dietary Guidelines for Americans Index (DGAI) was created to assess adherence to the Dietary recommendations of the 2005 Dietary Guidelines for Americans (DGA) in relation to chronic disease risk. Objective: The objective was to assess the relation between Dietary patterns consistent with the 2005 DGA as measured by the DGAI and both the prevalence of the metabolic syndrome (MetS) and individual MetS risk factors. Design: DGAI scores and metabolic risk factors for MetS were assessed in a cross-sectional study of 3177 participants from the Framingham Heart Study Offspring Cohort. MetS was defined on the basis of the National Cholesterol Education Program Adult Treatment Panel III criteria. Results: After adjustment for potential confounders, the DGAI score was inversely related to waist circumference (P for trend < 0.001), triacylglycerol concentration (P for trend = 0.005), both diastolic (P for trend = 0.002) and systolic (P for trend = 0.01) blood pressure, the prevalence of abdominal adiposity (P for trend < 0.001), and hyperglycemia (P for trend = 0.03). The prevalence of MetS was significantly lower in individuals in the highest DGAI quintile category than in those in the lowest category (odds ratio: 0.64; 95% CI: 0.47, 0.88; P for trend = 0.005) when those being treated for any of the risk factors were excluded. There was a significant interaction between DGAI score and age; the association between the DGAI score and MetS was confined largely to adults younger than 55 y (odds ratio: 0.57; 95% CI: 0.36, 0.92; P for trend <0.01). Conclusions: A Dietary pattern consistent with the 2005 DGA was associated with a lower prevalence of MetS-a potential risk factor for CVD.

the 2005 Dietary Guidelines for americans adherence index development and application
Journal of Nutrition, 2006Co-Authors: Jeanene J Foglicawley, Johanna T Dwyer, Marjorie L Mccullough, Edward Saltzman, Lisa M Troy, Paul F JacquesAbstract:The sixth edition of the Dietary Guidelines for Americans (DGA) was released in January 2005, with revised healthy eating recommendations for all adult Americans. We developed the 2005 Dietary Guidelines Adherence Index (DGAI) as a measure of adherence to the key Dietary intake recommendations. Eleven index items assess adherence to energy-specific food intake recommendations, and 9 items assess adherence to "healthy choice" nutrient intake recommendations. Each item was scored from a minimum of 0 to a maximum of 1, depending on the degree of adherence to the recommendation. A score of 0.5 was given for partial adherence on most items or for exceeding the recommendation for energy-dense food items. The DGAI was applied to Dietary data collected at the fifth examination of the Framingham Heart Study Offspring Cohort. The mean DGAI score was 9.6 (range 2.5-17.50). Those with higher DGAI scores were more likely to be women, older, multivitamin supplement users, and have a lower BMI and less likely to be smokers. The DGAI demonstrated a reasonable variation in this population of adult Americans, and by design this index was independent of energy consumption. The DGAI also demonstrated face validity based on the observed associations of the index with participant characteristics. Given these attributes, this index should provide a useful measure of diet quality and adherence to the new 2005 Dietary Guidelines for Americans.

development of healthy and sustainable food based Dietary Guidelines for the netherlands
Public Health Nutrition, 2019Co-Authors: Elizabeth J Brink, Corne Van Dooren, Marjolein Geurts, Ido Toxopeus, Caroline T M Van Rossum, Astrid Postmasmeets, Annette Stafleu, Danielle Wolvers, Elly J M Buurmarethans, M C OckeAbstract:Objective:To derive healthy and sustainable food-based Dietary Guidelines (FBDG) for different target groups in the Netherlands and describe the process.Design:Optimised Dietary patterns for children, adolescents, adults and the elderly were calculated using an optimisation model. Foods high in saturated and trans-fatty acids, salt and sugar, and low in Dietary fibre, were excluded. The Dietary patterns resembled the current food consumption as closely as possible, while simultaneously meeting recommendations for food groups, nutrients, maximum limits for foods with a high environmental impact, and within 85 % of the energy requirement. Recommended daily amounts of food groups were based on the optimised Dietary patterns and expert judgement.Setting:The Netherlands.Participants:FBDG were derived for Dutch people with different ages, genders, activity levels and food preferences.Results:For most target groups the optimisation model provided Dietary patterns that complied with all requirements. For some food groups, the optimised amounts varied largely between target groups. For consistent messages to consumers, the optimised Dietary patterns were adjusted to uniform recommendations per target group. Recommendations were visualised in the Wheel of Five. The advice is to eat the recommended amounts of foods according to the Wheel of Five and limit consumption of other foods.Conclusions:Based on an optimisation model, scientific evidence, information on Dietary patterns and expert knowledge, we derived FBDG for different target groups. The Wheel of Five is a key food-counselling model that can help Dutch consumers to make their diets healthier and more environmentally sustainable.

healthy diets with reduced environmental impact the greenhouse gas emissions of various diets adhering to the dutch food based Dietary Guidelines
Food Research International, 2017Co-Authors: Mirjam E Van De Kamp, Corne Van Dooren, A Hollander, Marjolein Geurts, Elizabeth J Brink, Caroline Van Rossum, Sander Biesbroek, Elias De Valk, Ido Toxopeus, Elisabeth H M TemmeAbstract:Abstract Objective To determine the differences in environmental impact and nutrient content of the current Dutch diet and four healthy diets aimed at lowering greenhouse gas (GHG) emissions. Methods GHG emissions (as proxy for environmental impact) and nutrient content of the current Dutch diet and four diets adhering to the Dutch food based Dietary Guidelines (Wheel of Five), were compared in a scenario study. Scenarios included a healthy diet with or without meat, and the same diets in which only foods with relatively low GHG emissions are chosen. For the current diet, data from the Dutch National Food Consumption Survey 2007–2010 were used. GHG emissions (in kg CO 2 -equivalents) were based on life cycle assessments. Results are reported for men and women aged 19–30 years and 31–50 years. Results The effect on GHG emissions of changing the current Dutch diet to a diet according to the Wheel of Five (corresponding with the current diet as close as possible), ranged from − 13% for men aged 31–50 years to + 5% for women aged 19–30 years. Replacing meat in this diet and/or consuming only foods with relatively low GHG emissions resulted in average GHG emission reductions varying from 28–46%. In the scenarios in which only foods with relatively low GHG emissions are consumed, fewer Dietary reference intakes (DRIs) were met than in the other healthy diet scenarios. However, in all healthy diet scenarios the number of DRIs being met was equal to or higher than that in the current diet. Conclusions Diets adhering to food based Dietary Guidelines did not substantially reduce GHG emissions compared to the current Dutch diet, when these diets stayed as close to the current diet as possible. Omitting meat from these healthy diets or consuming only foods with relatively low associated GHG emissions both resulted in GHG emission reductions of around a third. These findings may be used to expand food based Dietary Guidelines with information on how to reduce the environmental impact of healthy diets.
