Lazarova SV, Sutherland JM, Jessri M. Adherence to emerging plant-based dietary patterns and its association with cardiovascular disease risk in a nationally representative sample of Canadian adults. Am J Clin Nutr 2022; 116:57-73. [PMID: 35265975 PMCID: PMC9257478 DOI: 10.1093/ajcn/nqac062] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 03/07/2022] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Little is known about the role of emerging plant-based dietary patterns in cardiovascular disease (CVD) risk at the national population level. OBJECTIVES The objectives of this research were to assess the validity and reliability of newly established plant-based dietary indices, and to evaluate their associations with CVD risk among Canadian adults. METHODS Data were obtained from repeated 24-h dietary recalls of adult participants in the cross-sectional, nationally representative Canadian Community Health Survey cycle 2004 linked to health administrative databases (n = 12,323) and cycle 2015 (n = 14,026). Plant-based diet quality was assessed with a revised Plant-based Dietary Index (PDI), EAT-Lancet Reference Diet (ERD) score, and the latest Dietary Guidelines for Americans Adherence Index (DGAI) 2020. Weighted multivariate analyses were used for testing associations between diet quality and lifestyle characteristics, and weighted multivariable-adjusted Cox proportional hazards models for associations with CVD risk. RESULTS Construct validity was confirmed for the revised PDI and DGAI 2020 (but not the ERD) because participants in the highest (healthiest) quartile, compared to those in the lowest (least healthy), were more likely to be female (mean ± SE: 52.63% ± 1.27% compared with 44.80% ± 1.65% for revised PDI; 59.37% ± 2.01% compared with 40.84% ± 1.71% for DGAI 2020), older (mean ± SE: 50.55 ± 0.39 y compared with 45.56 ± 0.43 y for revised PDI; 51.57 ± 0.39 y compared with 46.35 ± 0.54 y for DGAI 2020), to have postsecondary education (mean ± SE: 32.36% ± 1.55% compared with 21.12% ± 1.31% for revised PDI; 34.17% ± 2.69% compared with 17.87% ± 0.98% for DGAI 2020), and less likely to be daily smokers (mean ± SE: 8.21% ± 1.0% compared with 17.06% ± 1.45% for revised PDI; 7.36% ± 1.71% compared with 21.53% ± 1.58% for DGAI 2020) (P-trend < 0.0001). No significant associations were observed between dietary index scores and CVD risk. CONCLUSIONS The revised PDI and DGAI 2020 provided valid and meaningful measures of plant-based eating among Canadians, whereas the validity of the ERD was not directly confirmed. Adherence to the plant-based dietary patterns was not associated with CVD risk. Future large-scale studies are necessary to further evaluate the role of plant-based eating in CVD prevention.

Abstract
BACKGROUND Hybrid methods of dietary patterns analysis have emerged as a unique and informative way to study diet-disease relationships in nutritional epidemiology research. OBJECTIVE To identify an obesogenic dietary pattern using weighted partial least squares (wPLS) in nationally representative Canadian survey data, and to identify key foods and/or beverages associated with the defined dietary pattern. DESIGN Data from one 24-hr dietary recall data from the cross-sectional Canadian Community Health Survey-Nutrition (CCHS) 2015 (n = 12,049) were used. wPLS was used to identify an obesogenic dietary pattern from 40 standardized food and beverage categories using the variables energy density, fibre density, and total fat as outcomes. The association between the derived dietary pattern and likelihood of obesity was examined using weighted multivariate logistic regression. Key dietary components highly associated with the derived pattern were identified. RESULTS Compared to quartile one (i.e. those least adherent to an obesogenic dietary pattern), those in quartile four had 2.40-fold increased odds of being obese (OR = 2.40, 95% CI = 1.91, 3.02, P-trend< 0.0001) with a monotonically increasing trend. Using a factor loading significance cut-off of ≥|0.17|, three food/beverage categories loaded positively for the derived obesogenic dietary pattern: fast food (+0.32), carbonated drinks (including energy drinks, sports drinks and vitamin water) (+0.30), and salty snacks (+0.19). Seven categories loaded negatively (i.e. in the protective direction): whole fruits (-0.40), orange vegetables (-0.32), "other" vegetables (-0.32), whole grains (-0.26), dark green vegetables (-0.22), legumes and soy (-0.18) and pasta and rice (-0.17). CONCLUSION This is the first study to apply weighted partial least squares to CCHS 2015 data to derive a dietary pattern associated with obesity. The results from this study pinpoint key dietary components that are associated with obesity and consumed among a nationally representative sample of Canadians adults.

Abstract
Background: Analyzing the effects of dietary patterns is an important approach for examining the complex role of nutrition in the etiology of obesity and chronic diseases.Objectives: The objectives of this study were to characterize the dietary patterns of Canadians with the use of a priori, hybrid, and simplified dietary pattern techniques, and to compare the associations of these patterns with obesity risk in individuals with and without chronic diseases (unhealthy and healthy obesity).Design: Dietary recalls from 11,748 participants (≥18 y of age) in the cross-sectional, nationally representative Canadian Community Health Survey 2.2 were used. A priori dietary pattern was characterized with the use of the previously validated 2015 Dietary Guidelines for Americans Adherence Index (DGAI). Weighted partial least squares (hybrid method) was used to derive an energy-dense (ED), high-fat (HF), low-fiber density (LFD) dietary pattern with the use of 38 food groups. The associations of derived dietary patterns with disease outcomes were then tested with the use of multinomial logistic regression.Results: An ED, HF, and LFD dietary pattern had high positive loadings for fast foods, carbonated drinks, and refined grains, and high negative loadings for whole fruits and vegetables (≥|0.17|). Food groups with a high loading were summed to form a simplified dietary pattern score. Moving from the first (healthiest) to the fourth (least healthy) quartiles of the ED, HF, and LFD pattern and the simplified dietary pattern scores was associated with increasingly elevated ORs for unhealthy obesity, with individuals in quartile 4 having an OR of 2.57 (95% CI: 1.75, 3.76) and 2.73 (95% CI: 1.88, 3.98), respectively (P-trend < 0.0001). Individuals who adhered the most to the 2015 DGAI recommendations (quartile 4) had a 53% lower OR of unhealthy obesity (P-trend < 0.0001). The associations of dietary patterns with healthy obesity and unhealthy nonobesity were weaker, albeit significant.Conclusions: Consuming an ED, HF, and LFD dietary pattern and lack of adherence to the recommendations of the 2015 DGAI were associated with a significantly higher risk of obesity with and without accompanying chronic diseases.

Abstract
BACKGROUND Dietary pattern analysis represents a departure from the traditional focus on single foods and nutrients and provides a comprehensive understanding of the role of the diet in chronic disease prevention and etiology. Dietary patterns of Canadians have not been evaluated comprehensively with the use of an updated a priori dietary quality index. OBJECTIVES We aimed to update the Dietary Guidelines for Americans Adherence Index (DGAI) on the basis of the 2015 Dietary Guidelines for Americans (DGA), to evaluate the construct validity and reliability of the revised index, and to examine whether closer adherence to this index is associated with a lower risk of obesity with or without an accompanying chronic disease. DESIGN Data from 11,748 participants (≥18 y of age) in the cross-sectional Canadian Community Health Survey cycle 2.2 were used in weighted multivariate analyses. Multinomial logistic regression was used to test the association between diet quality and obesity risk. RESULTS With the use of principal component analyses, the multidimensionality of the 2015 DGAI was confirmed, and its reliability was shown with a high Cronbach's α = 0.75. Moving from the first to the fourth (healthiest) quartile of the 2015 DGAI score, there was a trend toward decreased energy (2492 ± 26 compared with 2403 ± 22 kcal, respectively; ±SE) and nutrients of concern (e.g., sodium), whereas intakes of beneficial nutrients increased (P-trend < 0.05). In the age- and sex-adjusted model, a lack of adherence to the 2015 DGA recommendations increased the OR of being unhealthy obese from 1.42 (95% CI: 1.02, 1.99) in quartile 3 to 2.08 (95% CI: 1.49, 2.90) in quartile 2 to 2.31 (95% CI: 1.65, 3.23) in the first quartile of the 2015 DGAI score, compared with the fourth quartile (healthiest) (P-trend < 0.0001). The odds of being obese without a chronic disease (healthy obese) and having a chronic disease without being obese also increased in the lowest DGAI quartile compared with the highest DGAI quartile, albeit not as much as in the unhealthy obese group. CONCLUSION The 2015 DGAI provides a valid and reliable measure of diet quality among Canadians.

Association between barriers and facilitators to meeting the Dietary Guidelines for Americans and body weight status of caregiver-child dyads: the Healthy Eating and Lifestyle for Total Health Study. Am J Clin Nutr 2016; 104:143-54.

Abstract
BACKGROUND Few Americans meet the Dietary Guidelines for Americans (DGA), yet a large percentage are overweight. OBJECTIVE The goal of this research was to examine the association between barriers and facilitators to meeting the DGA and weight in a multisite study. DESIGN This was a cross-sectional study in which 836 caregiver-child dyads among 3 race/ethnic groups completed the questionnaire across 6 sites participating in the HEALTH (Healthy Eating and Lifestyle for Total Health) Study. Barriers and facilitators to meeting the DGA were assessed by using a validated questionnaire developed specifically for the HEALTH Study. Heights and weights were measured. A series of bivariate regression analyses were conducted to examine the association between caregiver body mass index (BMI) or child BMI z score and the barriers and facilitators to meeting the DGA, adjusting for appropriate covariates in the models. Path analysis was used to examine the relation of caregiver and child barriers and facilitators to their relative BMIs. RESULTS In children, the BMI z score was associated positively (P < 0.001) with total barriers and negatively (P < 0.001) with total facilitators. In caregivers, BMI was associated positively only with total barriers (P < 0.0001). For each of the 8 MyPyramid components, barriers consistently were associated positively (P < 0.0001) and facilitators were associated negatively (P < 0.001) with BMI z score in children (with the exception of the fruit and physical activity components). For caregivers, most of the barriers to meeting recommendations for meats and beans; solid fats, alcohol, and added sugars; and physical activity components were associated positively (P < 0.01) with BMI. Path analyses show that caregiver facilitators were significantly related to children's facilitators to meeting DGA recommendations (standardized β: 0.12; P < 0.001). CONCLUSION To our knowledge, our findings are among the first to show associations between weight and barriers and/or facilitators to meeting the DGA in a national, large sample of caregiver-child dyads. This trial was registered at clinicaltrials.gov as NCT02725970.

Abstract
AbstractObjectiveThe objective of the present study was to examine the relationship between plasma alkyresorcinol (AR) concentrations, which are biomarkers of whole-grain intake, and atherosclerotic progression over 3 years in postmenopausal women with coronary artery disease.DesignPlasma AR concentrations were measured by a validated GC–MS method in fasting plasma samples. Atherosclerosis progression was assessed using change in mean minimal coronary artery diameter (MCAD) and percentage diameter stenosis (%ST), based on mean proximal vessel diameter across up to ten coronary segments. Dietary intake was estimated using a 126-item interviewer-administered FFQ.SettingA prospective study of postmenopausal women participating in the Estrogen Replacement and Atherosclerosis trial.SubjectsFor the analysis of plasma AR concentrations and atherosclerotic progression, plasma samples and follow-up data on angiography were available for 182 women.ResultsMean whole-grain intake was 9·6 (se 0·6) servings per week. After multivariate adjustment, no significant associations were observed between plasma AR concentrations and change in mean MCAD or progression of %ST. Plasma AR concentrations were significantly correlated with dietary whole grains (r=0·35, P<0·001), cereal fibre (r=0·33, P<0·001), bran (r=0·15, P=0·05), total fibre (r=0·22, P=0·003) and legume fibre (r=0·15, P=0·04), but not refined grains, fruit fibre or vegetable fibre.ConclusionsPlasma AR concentrations were not significantly associated with coronary artery progression over a 3-year period in postmenopausal women with coronary artery disease. A moderate association was observed between plasma AR concentrations and dietary whole grains and cereal fibre, suggesting it may be a useful biomarker in observational studies.

Abstract
BACKGROUND Maintaining health and well-being in aging populations is critical. OBJECTIVE To examine the association between dietary patterns in midlife and prevalence of healthy aging. DESIGN Cross-sectional observational study. SETTING Nurses' Health Study. PARTICIPANTS 10 670 women with dietary data and no major chronic diseases between 1984 and 1986, when they were in their late 50s and early 60s (median age, 59 years). Women provided information on health an average of 15 years later. MEASUREMENTS Diet quality in midlife was ascertained using the Alternative Healthy Eating Index-2010 (AHEI-2010) and Alternate Mediterranean diet scores, averaged from 2 food-frequency questionnaires (1984 to 1986). "Healthy" aging was defined as survival to 70 years or older with maintenance of 4 health domains: no major chronic diseases or major impairments in cognitive or physical function or mental health. RESULTS After multivariable adjustment, greater adherence to the AHEI-2010 (upper vs. lower quintiles) in midlife was related to 34% (95% CI, 9% to 66%; P for trend < 0.001) greater odds of healthy versus usual aging. Greater adherence to Alternate Mediterranean diet was related to 46% (CI, 17% to 83%; P for trend = 0.002) greater odds of healthy aging. When the 4 components of healthy aging were analyzed separately, the AHEI-2010 and Alternate Mediterranean diet were significantly associated with greater likelihood of no major limitations in physical function and mental health. LIMITATIONS Residual confounding was possible, although many confounding factors were considered. Bias due to complex patterns of measurement error within diet scores cannot be excluded. CONCLUSION Better diet quality at midlife seems to be strongly linked to greater health and well-being in persons surviving to older ages.

Abstract
People with healthy eating identities report healthier diets and demonstrate greater receptivity to nutrition interventions, but other types of eating identity are likely important. We developed the Eating Identity Type Inventory (EITI) to assess affinity with four eating identity types; healthy, meat, picky, and emotional. This study assessed factorial validity, using confirmatory factor analysis (CFA) and established reliability and convergent validity of the EITI. In a telephone survey, 968 primary household food shoppers completed the EITI and a dietary questionnaire; 101 repeated the EITI approximately 1month later.CFA revealed that an 11-item model provided acceptable fit (χ(2)=206; df=38), CFI=.938, NNFI=.925, RMSEA=.070; SRMR=.059). The EITI demonstrated acceptable internal consistencies with Cronbach alpha's ranging from .61 to .82 and good test-retest reliability for healthy, emotional, and picky types (Pearson's correlations ranging from .78 to .84). Ordinary Least Squares (OLS) used to assess relationships between eating identity type and diet analyses demonstrated significant hypothesized relationships between healthy eating identity and healthier dietary intake and meat and picky eating identities and less healthy dietary intake. The EITI could facilitate behavioral and cognitive research to yield important insights for ways to more effectively design messages, interventions, and policies to promote healthy dietary behaviors.

Abstract
The Healthy Eating Index-2005 (HEI-2005) measures adherence to the 2005 Dietary Guidelines for Americans, but the association between the HEI-2005 and risk of chronic disease is not known. The Alternative Healthy Eating Index (AHEI), which is based on foods and nutrients predictive of chronic disease risk, was associated inversely with chronic disease risk previously. We updated the AHEI, including additional dietary factors involved in the development of chronic disease, and assessed the associations between the AHEI-2010 and the HEI-2005 and risk of major chronic disease prospectively among 71,495 women from the Nurses' Health Study and 41,029 men from the Health Professionals Follow-Up Study who were free of chronic disease at baseline. During ≥24 y of follow-up, we documented 26,759 and 15,558 incident chronic diseases (cardiovascular disease, diabetes, cancer, or nontrauma death) among women and men, respectively. The RR (95% CI) of chronic disease comparing the highest with the lowest quintile was 0.84 (0.81, 0.87) for the HEI-2005 and 0.81 (0.77, 0.85) for the AHEI-2010. The AHEI-2010 and HEI-2005 were most strongly associated with coronary heart disease (CHD) and diabetes, and for both outcomes the AHEI-2010 was more strongly associated with risk than the HEI-2005 (P-difference = 0.002 and <0.001, respectively). The 2 indices were similarly associated with risk of stroke and cancer. These findings suggest that closer adherence to the 2005 Dietary Guidelines may lower risk of major chronic disease. However, the AHEI-2010, which included additional dietary information, was more strongly associated with chronic disease risk, particularly CHD and diabetes.

Abstract
For decades, oxidative stress has been discussed as a key mechanism of endothelial dysfunction and cardiovascular disease. However, attempts to validate and exploit this hypothesis clinically by supplementing antioxidants have failed. Nevertheless, this does not disprove the oxidative stress hypothesis. As a certain degree of reactive oxygen species (ROS) formation appears to be physiological and beneficial. To reduce oxidative stress therapeutically, two alternative approaches are being developed. One is the repair of key signalling components that are compromised by oxidative stress. These include uncoupled endothelial nitric oxide (NO) synthase and oxidized/heme-free NO receptor soluble guanylate cyclase. A second approach is to identify and effectively inhibit the relevant source(s) of ROS in a given disease condition. A highly likely target in this context is the family of NADPH oxidases. Animal models, including NOX knockout mice and new pharmacological inhibitors of NADPH oxidases have opened up a new era of oxidative stress research and have paved the way for new cardiovascular therapies.

Abstract
Coronary heart disease (CHD) is the leading cause of death in women. A nested case-control study tested whether dietary patterns predicted CHD events among 1224 participants in the Women's Health Initiative-Observational Study (WHI-OS) with centrally confirmed CHD, fatal or nonfatal myocardial infarct compared to 1224 WHI-OS controls matched for age, enrollment date, race/ethnicity, and absence of CHD at baseline or follow-up. The first six principal components explained >75% of variation in dietary intakes and K-mean analysis based on these six components produced three clusters. Diet cluster 1 was rich in carbohydrate, vegetable protein, fiber, dietary vitamin K, folate, carotenoids, α-linolenic acid [18:3(n-3)], linoleic acid [18:2(n-6)], and supplemental calcium and vitamin D. Diet cluster 2 was rich in total and animal protein, arachidonic acid [20:4(n-6)], DHA [22:6(n-3)], vitamin D, and calcium. Diet cluster 3 was rich in energy, total fat, and trans fatty acids (all P < 0.01). Conditional logistic regression analysis demonstrated diet cluster 1 was associated with lower CHD risk than diet cluster 2 (reference group) adjusted for smoking, education, and physical activity [OR = 0.79 (95% CI = 0.64, 0.99); P = 0.038]. This difference was not significant after adjustment for BMI and systolic blood pressure. Diet cluster 3 was associated with higher CHD risk than diet cluster 2 [OR = 1.28 (95% CI = 1.04, 1.57); P = 0.019], but this difference did not remain significant after adjustment for smoking, education, and physical activity. Within this WHI-OS cohort, distinct dietary patterns may be associated with subsequent CHD outcomes.

Abstract
Consumption of a diet consistent with dietary guidelines is believed to have a beneficial effect on the prevention of chronic diseases and the promotion of general health. This study was conducted to explore the relationship between adherence to the Korean Food Guidance System (KFGS), which was based on the 2010 revised KDRIs, and the risk of metabolic abnormalities. Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data were collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. The number of servings consumed from each food group was compared to the KFGS recommended servings for each of the 6 food groups. Poor adherence to the recommendations for servings of milk and dairy products (OR: 2.038, 1.128-3.682) was associated with a higher risk of MetS, and poor adherence to the guidelines for fruit consumption (OR: 1.849, 1.027-3.329) was associated with a higher risk for the existence an elevated waist circumference. Conversely, the consumption of meat, fish, eggs, and beans above the recommended number of servings was associated with a lower risk of having an elevated waist circumference (OR: 0.523, 0.288-0.950), and the consumption of vegetables above the recommended number of servings was associated with a reduced risk of having elevated fasting glucose (OR: 0.533, 0.298-0.954). These results suggest that adherence to the KFGS guidelines helps to prevent the development of MetS, but this association needs to be confirmed by prospective studies.

Abstract
The process of atherosclerosis may begin in youth and continue for decades, leading to both nonfatal and fatal cardiovascular events, including myocardial infarction, stroke, and sudden death. With primordial and primary prevention, cardiovascular disease is largely preventable. Clinical trial evidence has shown convincingly that pharmacological treatment of risk factors can prevent events. The data are less definitive but also highly suggestive that appropriate public policy and lifestyle interventions aimed at eliminating tobacco use, limiting salt consumption, encouraging physical exercise, and improving diet can prevent events. There has been concern about whether efforts aimed at primordial and primary prevention provide value (ie, whether such interventions are worth what we pay for them). Although questions about the value of therapeutics for acute disease may be addressed by cost-effectiveness analysis, the long time frames involved in evaluating preventive interventions make cost-effectiveness analysis difficult and necessarily flawed. Nonetheless, cost-effectiveness analyses reviewed in this policy statement largely suggest that public policy, community efforts, and pharmacological intervention are all likely to be cost-effective and often cost saving compared with common benchmarks. The high direct medical care and indirect costs of cardiovascular disease-approaching $450 billion a year in 2010 and projected to rise to over $1 trillion a year by 2030-make this a critical medical and societal issue. Prevention of cardiovascular disease will also provide great value in developing a healthier, more productive society.

Abstract
Although dietary fat and its role in cardiovascular prevention has been one of the most extensively studied nutritional topics, it continues to be an ever-expanding research area. Particularly thanks to studies on Mediterranean diet, we now know that fat quality is more relevant than the amount of fat we eat in the diet. Thus, saturated and trans fats have been found to increase the risk of atherogenic disease. This is why it is recommended to substitute complex carbohydrates or unsaturated fat for unsaturated and trans fats with the aim of reducing saturated and trans fat intake to <10% and <1%, respectively, of the total calorie intake. Recent population studies, particularly that conducted in Kuopio, Finland, and those on Mediterranean diet, stress the important role of monounsaturated and polyunsaturated fats as key nutrients in preventing cardiovascular disease in modern societies. Furthermore, a special type of polyunsaturated fatty acids, i.e. those of the omega-3 (n-3) series, is increasingly becoming essential nutrients for a healthy diet, especially in the case of children. Therefore, there is a rationale for four the Scientific Societies that are strongly committed to disseminate the benefits of a healthy diet in preventing cardiovascular disease, and to prepare a joint statement with the purpose of spreading improved knowledge on the importance of changing to a healthy diet with a well-balanced fat intake for industrialized populations. Accordingly, a multidisciplinary panel of experts from the following institutions has developed the present joint statement targeted at both adults and children of different ages: Spanish Society of Arteriosclerosis, Spanish Society of Family and Community Medicine, Spanish Association of Paediatrics, Spanish Society of Gastroenterology, Hepatology and Paediatric Nutrition and Dietetics, and Spanish Society for Food Sciences.

Abstract
Americans are under assault by a fierce epidemic of obesity, diabetes, and cardiovascular disease, of their own doing. Lowered death rates from heart disease and reduced rates of smoking are seriously threatened by the inexorable rise in overweight and obesity. Latest data indicate that 32% of children are overweight or obese, and fewer than 17% exercise sufficiently. Over 68% of adults are overweight, 35% are obese, nearly 40% fulfill criteria for the metabolic syndrome, 8–13% have diabetes, 34% have hypertension, 36% have prehypertension, 29% have prediabetes, 15% of the population with either diabetes, hypertension, or dyslipidemia are undiagnosed, 59% engage in no vigorous activity, and fewer than 5% of the US population qualifies for the American Heart Association (AHA) definition of ideal cardiovascular health. Health, nutrition, and exercise illiteracy is prevalent, while misinformation and unrealistic expectations are the norm. Half of American adults have at least one cardiovascular risk factor. Up to 65% do not have their conventional risk biomarkers under control. Of those patients with multiple risk factors, fewer than 10% have all of them adequately controlled. Even when patients are treated according to evidence-based protocols, about 70% of cardiac events remain unaddressed. Undertreatment is also common. Poor patient adherence, probably well below 50%, adds further difficulty in reducing cardiovascular risk. Available data indicate that only a modest fraction of the total cardiovascular risk burden in the population is actually now being eliminated. A fresh view of these issues, a change in current philosophy, leading to new and different, multimechanistic methods of prevention may be needed. Adherence to published guidelines will improve substantially outcomes in both primary and secondary prevention. Primordial prevention, which does not allow risk values to appear in a population, affords more complete protection than subsequent partial reversal of elevated risk factors or biomarkers. Current evidence supports recent calls for massive educational programs supporting primordial prevention, individual responsibility and pride in achieving population-wide ideal cardiovascular health through lifestyle modification. Environmental and social changes will be necessary, along with major supportive adjustments in the food industry and the assistance of the media. Cooperation is critical to the success of such an initiative.

Abstract
The European Union is implementing a new regulatory framework for nutrition and health claims (HCs) that will greatly impact the communication of health messages on foodstuffs. In particular, approved HCs will be included in a positive register of generic claims. In the currently available literature, assessment of the relevance of HCs has mainly been related to scientific substantiation, and the issue of relevance in terms of public health has tended to be overlooked. Interestingly, the new regulation states that claims must be well understood by the average consumer. This article delves beyond the issue of scientific substantiation of claims and reviews possible discrepancies between consumer perception/understanding of HCs and the public health nutrition reality, which can confuse or mislead the consumer and ultimately impact public health nutrition. Six pitfalls are described herein and a comprehensive overview of the critical examination of any HC is proposed.

Abstract
Clearly defined processes exist for developing evidence-based guidelines in clinical medicine. Approaches such as the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) where recommendations are made on the basis of quality of evidence gathered in a systematic literature review are also appropriate for recommendations relating to nutritional management of disease. Strong recommendations are based on high-quality evidence derived from randomized controlled trials (RCTs). In nutritional studies, RCTs often examine risk factors and occasionally other surrogates of disease rather than clinical end-points. Criteria are suggested as to when such surrogates may be used. GRADE and similar approaches are less appropriate when considering recommendations regarding chronic disease prevention. Cancer develops over many years, and RCTs exploring nutritional measures to reduce risk are inappropriate. The World Cancer Research Fund (WCRF) has developed an approach in which recommendations are based on clearly defined 'convincing' or 'probable' relationships between nutritional variables and disease outcomes. The WCRF criteria have been adapted for developing a wide range of policy recommendations which provide opportunities for those responsible for implementing policy to select options best suited to their purpose. Recommendations related to nutrition policy tend to evolve as a delicate balance between political wisdom and judgement of the scientific evidence. However, policy recommendations are important since they have the potential to create environments which are conducive to the behavioural changes required for improved nutrition.

Abstract
OBJECTIVE The Nordic countries have published joint dietary recommendations, the Nordic Nutrition Recommendations (NNR), since 1980. We evaluated adherence to the NNR as a measure of a healthy diet and its potential association with self-reported upper respiratory tract infection (URTI). DESIGN A prospective, population-based study with a follow-up period of 4 months. Dietary intake was assessed using a semi-quantitative FFQ with ninety-six items, along with other lifestyle factors, at baseline. URTI was assessed every three weeks. A Poisson regression model was used to control for age, sex and other confounding factors. SETTING A middle-sized county in northern Sweden. SUBJECTS Swedish men and women (n 1509) aged 20-60 years. RESULTS The NNR include recommendations on macronutrient proportions, physical activity and intake of micronutrients, sodium, fibre and alcohol. We found that overall adherence to the NNR was moderately good. In addition, we found that high adherence to the NNR (>5·5 adherence points) was not associated with a lower risk of URTI (incidence rate ratio (IRR) 0·89, 95% CI 0·73, 1·08) compared with low adherence (<4·5 adherence points). When investigating individual components of the NNR, only high physical activity was associated with lower URTI risk (IRR = 0·82, 95% CI 0·69, 0·97) whereas none of the dietary components were associated with risk of URTI. CONCLUSIONS Overall adherence to the NNR was moderately good. Overall adherence to the NNR was not associated with URTI risk in our study. However, when investigating individual components of the NNR, we found that high physical activity was associated with lower URTI risk.
