RESUMEN
BACKGROUND: Numerous studies have shown inverse associations between serum magnesium (Mg) and risk of cardiovascular disease (CVD), but studies of dietary Mg have not been consistent. AIM: To examine the association of a Mg-rich diet score with risks of CVD, coronary heart disease (CHD), and ischemic stroke in the Atherosclerosis Risk in Communities (ARIC) study. METHODS: There were 15,022 Black and White adults without prevalent CVD at baseline (1987-89) included in this analysis. Diet was assessed at two visits 6 years apart using an interviewer-administered 66-item food frequency questionnaire. A Mg-rich diet score was created that included servings of whole grain products, nuts, vegetables, fruit, legumes, coffee, and tea. Cox proportional hazard regression evaluated associations of incident CVD, CHD and stroke across quintiles of Mg-rich diet score, adjusting for demographics, lifestyle factors, and clinical characteristics. RESULTS: Over >30 years of follow-up, there were 3,531 incident CVD events (2,562 CHD, 1,332 ischemic stroke). Participants who consumed more Mg-rich foods were older, female, White, had lower blood pressure, fewer were not current smokers, and more reported being physically active. A Mg-rich diet was inversely associated with incident CVD (HRQ5 vs Q1=0.87, 95%CI: 0.77-0.98, ptrend=0.02) CHD (HRQ5 vs Q1=0.82, 95%CI: 0.71-0.95, ptrend=0.01); however, the diet-stroke association was null (HRQ5 vs Q1=1.00, 95%CI: 0.82-1.22, ptrend=0.97). CONCLUSIONS: Consuming a diet including Mg-rich foods, such as whole grains, nuts, vegetables, fruits, legumes, coffee and tea, is associated with lower risk of CVD and CHD, but not ischemic stroke.
This study showed an inversely association between a magnesium-rich (mg-rich) diet score and risk of cardiovascular disease (CVD) in adults aged 45-64 at baseline (1987-89) and followed for over 30 years. The mg-rich diet score was created by summing the reported number of daily servings consumed from whole grain products, fruit, vegetables, legumes, nuts, coffee and tea.A mg-rich diet score may be associated with lower risk of developing CVD and coronary heart disease, but not ischemic stroke.
RESUMEN
The impact of dietary intake on cognitive outcomes and dementia prevention is a topic of increasing interest. Meta-analyses of observational studies, mostly conducted within US and European populations, have reported benefits of healthy diet patterns on cognitive performance, but results from individual studies have been inconsistent. These inconsistencies are likely due to the diverse methodology used in studies, including different diet and cognitive function assessment instruments, follow-up periods, and analytical methods, which make drawing conclusions relevant to dietary guidance challenging. The objective of this project is to describe a protocol to conduct a retrospective harmonization study on dietary intake and cognitive health using data from European and US studies. The recommendations resulting from the project can be used to support evidence-based synthesis for future iterations of the Dietary Guidelines for Americans or other population-based dietary guidance. Additionally, this study will serve as a harmonization guide for future research on the relationship between diet patterns and cognition. The approach outlined ultimately aims to optimize resources and expedite research efforts for dementia prevention.
RESUMEN
AIMS: Numerous studies report positive associations between total carbohydrate (CHO) intake and incident metabolic syndrome (MetS), but few differentiate quality or type of CHO relative to MetS. We examined source of CHO intake, including added sugar (AS), AS-rich CHO foods, and sugar-sweetened beverages (SSBs) associated with incident MetS in adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. METHODS AND RESULTS: Among 3154 Black American and White American women and men aged 18-30 years at baseline, dietary intake was assessed by diet history three times over 20 years. Sources of AS-rich CHO foods and beverages include sugar-rich refined grain products, candy, sugar products, and SSBs. Incident MetS was created according to standard criteria. Time-dependent Cox proportional hazards regression analysis evaluated the associations of incident MetS across quintiles of cumulative intakes of AS-rich CHO foods and beverages, AS, and SSBs adjusted for potential confounding factors over 30 years of follow-up. The associations of AS-rich CHO foods and beverages, AS, and SSB intakes with incident MetS were consistent. Compared with the lowest intake, the greatest intakes of AS-rich CHOs, AS, and SSBs were associated with 59% (Ptrend < 0.001), 44% (Ptrend = 0.01), and 34% (Ptrend = 0.03) higher risk of developing MetS, respectively. As expected, diet quality was lower across increasing quintiles of AS-rich CHO foods and beverages, AS, and SSBs (all Ptrend < 0.001). CONCLUSION: Our study findings are consistent with an elevated risk of developing MetS with greater consumption of AS, AS-rich CHO foods, and SSBs, which support consuming fewer AS-rich CHO foods and SSBs.
Metabolic syndrome (MetS) is a condition consisting of three out of five heart disease risk factors. Researchers have found that the risk of developing MetS increases as carbohydrate (CHO) intake also increases. However, how this risk is related to the type and quality of CHO has not been well studied. To study this, we used data from 3154 African American and White American women and men aged 1830 years old at baseline (198586). Information was collected about their health and what they ate. This allowed us to find out if MetS occurred over time if it ever did. We determined how much added sugar (AS), sugar-sweetened beverages (SSBs), and AS-rich CHO foods and beverages they ate. Added sugarrich foods and beverages contain sugars, syrups, and caloric sweeteners added to them during production or preparation. Carbohydrate foods containing AS include refined grain breads, rolls, bakery products, candy, and jellies. We found that people with the greatest intake of AS, SSBs, and AS-rich CHO foods and beverages had a higher risk of developing MetS compared with those with the lowest intake. These results align with US Dietary Guidelines as well as European guidelines to consume less AS and, therefore, to consume fewer AS-rich CHO foods and SSBs.

BACKGROUND AND AIMS: Numerous prospective studies have examined sugar sweetened beverage (SSB) intake associated with weight gain or incident obesity. Because SSB accounts for only 33 % of added sugar (AS) intake, we investigated the associations of AS intake with change in weight and waist circumference and risk of developing obesity. METHODS AND RESULTS: At baseline (1985-86) Black and White women and men, aged 18-30 years, enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study and were followed for 30 years (2015-16). A diet history assessed dietary intake 3 times over 20 years. Multivariable linear regression evaluated the associations of change in weight (n = 3306) and waist circumference (n = 3296) across quartiles of AS, adjusting for demographics, lifestyle factors, and anthropometrics. Proportional hazards regression analysis evaluated the associations of time-varying cumulative AS intake with risk of incident obesity (n = 4023) and abdominal obesity (n = 3449), adjusting for the same factors. Over 30 years of follow-up, greater AS intake was associated with gaining 2.3 kg more weight (ptrend = 0.01) and 2.2 cm greater change in waist circumference (ptrend = 0.005) as well as increased risk of incident obesity (HR 1.28; 95 % CI: 1.08-1.53) and incident abdominal obesity (HR 1.27; 95 % CI:1.02-1.60). CONCLUSION: Our findings are consistent with recommendations from the 2020-2025 U S. Dietary Guidelines for Americans to limit daily AS intake.

BACKGROUND: Artificial sweetener (ArtSw) intakes have been previously associated with higher BMI in observational studies and may promote visceral and skeletal muscle adipose tissue (AT) accumulation. This study aimed to determine whether habitual, long-term ArtSw or diet beverage intakes are related to greater AT depot volumes and anthropometry-related outcomes. METHODS: A validated diet history questionnaire was administered at baseline, year 7, and year 20 examinations in 3088 men and women enrolled in the Coronary Artery Risk Development in Young Adults cohort (CARDIA), mean age of 25.2 years and mean BMI of 24.5 kg/m2 at baseline. Volumes of visceral (VAT), intermuscular (IMAT), and subcutaneous adipose tissue (SAT) were assessed by computed tomography at year 25. Linear regression evaluated associations of aspartame, saccharin, sucralose, total ArtSw, and diet beverage intakes with AT volumes, anthropometric measures, and 25-year change in anthropometry. Cox regression estimated associations of ArtSw with obesity incidence. Adjustments were made for demographic and lifestyle factors, total energy intake, and the 2015 healthy eating index. RESULTS: Total ArtSw, aspartame, saccharin, and diet beverage intakes were positively associated with VAT, SAT, and IMAT volumes (all ptrend ≤ 0.001), but no associations were observed for sucralose intake (all ptrend > 0.05). In addition, total ArtSw, saccharin, aspartame, and diet beverage intakes were associated with greater body mass index, body weight, waist circumference, and their increases over a 25-year period. Except for saccharin (ptrend = 0.13), ArtSw, including diet soda, was associated with greater risks of incident obesity over a median 17.5-year follow-up (all ptrend < 0.05). CONCLUSIONS: Results suggest that long-term intakes of aspartame, saccharin, or diet soda may increase AT deposition and risk of incident obesity independent of diet quality or caloric intake. Coupled with previous evidence, alternatives to national recommendations to replace added sugar with ArtSw should be considered since both may have health consequences.

BACKGROUND AND AIMS: Few studies have examined long-term associations of walnut, other nut, and no nut consumption with cardiovascular disease (CVD) risk factors. Results from prospective studies with long-term follow-up can provide further evidence for dietary guideline messaging to consume nuts. Therefore, we examined the associations of walnut, other nut, and no nut consumption with diet quality and CVD risk factors over 30 years of follow-up. METHODS AND RESULTS: Data were analyzed from 3092 young adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. Dietary intake, including walnuts and other nuts, was assessed 3 times over 20 years. CVD risk factors were measured at multiple exams. General linear regression evaluated the associations of walnut, other nut, and no nut consumption with CVD risk factors over 30 years (Y30) of follow-up. The 20-year cumulative mean intake of walnuts (0.74 oz/d), other nuts (1.6 oz/d), or no nut consumption was differentially associated with HEI-2015 and CVD risk factors by Y30. Generally, walnut consumers had significantly higher HEI-2015, lower body mass index, waist circumference, blood pressure, and triglyceride concentration, and gained less weight since baseline than other nut consumers (p ≤ 0.05 for all). Further, walnut consumers had lower fasting blood glucose than no nut consumers (p ≤ 0.05). CONCLUSION: Study findings that walnut and other nut consumption was associated with better CVD risk factors and diet quality aligns with the 2020-2025 US. Dietary Guidelines for Americans recommendation to consume nuts, such as walnuts, within the context of a healthy diet.

BACKGROUND AND AIMS: Various food groups have been associated with measures of left ventricular geometry and function. Whether the Dietary Approaches to Stop Hypertension (DASH) dietary pattern in mid-life is associated with a favorable cardiac structure and function later in life is unknown. METHODS AND RESULTS: The study population consisted of the Atherosclerosis Risk in Communities study participants free of cardiovascular disease at study visit 3 in 1993-1995. Dietary intake was assessed by food frequency questionnaire at study visits 1 (1987-1989) and 3 (1993-1995). Participants who underwent transthoracic echocardiograms at the Jackson field center at visit 3 (n = 1974) and at all field centers at study visit 5 (2011-2013; n = 4651) were included in this study. General linear regression was used to evaluate associations between dietary intake and markers of cardiac structure and function adjusting for potential confounders. Higher DASH score was associated with lower left ventricle mean wall thickness and higher absolute value of longitudinal strain at visit 5 (ptrend = 0.004 and < 0.001, respectively). CONCLUSION: The DASH dietary pattern in midlife was favorably associated with left ventricle structure and systolic function later in life. These results emphasize the importance of adhering to a healthy eating plan as one lifestyle measure to preserve cardiac structure and function.

BACKGROUND: Published studies are inconsistent about whether differences in diet are associated with risk of venous thromboembolism. We studied the association between dietary patterns and incident venous thromboembolism in a large US cohort. METHODS: The Atherosclerosis Risk in Communities study followed 14,818 middle-aged males and females for incident venous thromboembolism over an average of 22 years between 1987 and 2015. Trained interviewers assessed dietary intake at visits 1 and 3, using a food frequency questionnaire. We derived 2 dietary pattern scores using principal component analysis and ascertained and verified hospitalized venous thromboembolism. In separate proportional hazards regression analyses, we examined associations of quintiles of the prudent and the Western dietary pattern scores with risk of developing non-cancer-related and total venous thromboembolism, adjusting for demographic characteristics, lifestyle factors, body mass index, and diabetes. RESULTS: With 860 total incident venous thromboembolism events, the hazard ratios (95% confidence intervals) of incident non-cancer-related venous thromboembolism (n = 631) across quintiles of the prudent dietary pattern score were 1 (reference), 1.04 (0.81-1.32), 0.84 (0.65-1.08), 0.70 (0.53-0.91), and 0.88 (0.67-1.15), Ptrend = .04. Across quintiles of the Western dietary pattern score, hazard ratios of non-cancer-related venous thromboembolism were 1 (reference), 1.13 (0.87-1.45), 1.20 (0.92-1.56), 1.03 (0.77-1.39), and 1.58 (1.13-2.21), Ptrend = .04. Associations were similar for total venous thromboembolism. CONCLUSIONS: In this community-based cohort, a prudent dietary pattern was associated with a lower risk of future venous thromboembolism, whereas a Western dietary pattern was associated with a higher risk.

BACKGROUND AND AIMS: Observational studies and clinical trials have shown cardiovascular benefits of nut consumption, including walnuts. However, the relations of walnut consumption with systolic and diastolic function, risk factors for heart failure, are unknown. We examined the associations of walnut consumption with cardiac structure and function parameters in black and white adults enrolled in the Coronary Artery Risk Development in Young Adults (CARDIA) study. METHODS AND RESULTS: After exclusions, the study population included 3341 participants. Dietary intake was assessed using the CARDIA Diet History questionnaire at baseline, year 7 and year 20 exams. Cardiac structure and function were measured by echocardiography at year 25. Multivariable linear regression evaluated the associations of walnut consumption with blood pressure (BP), heart rate, and cardiac phenotypes, adjusting for age, sex, race, lifestyle habits, and clinical characteristics. We found the majority of walnut consumers compared to non-consumers were females, whites, and more highly educated, and had lower waist circumference, diastolic BP, and heart rate, and higher diet quality score. Even though cardiac structure and function measures were generally within normal ranges among participants, walnut consumers had significantly better values for diastolic function parameters A wave, E/A ratio, septal and lateral e' than non-consumers. Further adjustment for body mass index and diabetes status did not materially change the significance between walnut consumer groups. Systolic function parameters did not differ by walnut group. CONCLUSION: Compared to non-consumers, walnut consumption is associated with better diastolic dysfunction in young to middle-aged adults.

AIM: The purpose of this study was to determine the relationships of pericardial adipose tissue and visceral adipose tissue volume with added sugar and sugar-sweetened beverage intakes. We hypothesized that both added sugar and sugar-sweetened beverages were positively associated with pericardial adipose tissue and visceral adipose tissue volumes in black and white men and women enrolled in the prospective Coronary Artery Risk Development in Young Adults study. METHODS AND RESULTS: Dietary intake was assessed by diet history at baseline, year 7 and year 20 examinations in 3070 participants aged 18-30 and generally healthy at baseline. After 25 years follow-up, participants underwent a computed tomography scan of chest and abdomen; the computed tomography scans were read, and pericardial adipose tissue, visceral adipose tissue, and subcutaneous adipose tissue volumes were calculated. Quintiles were created for the average of baseline, year 7 and year 20 added sugar and for the average of sugar-sweetened beverages. General linear regression analysis evaluated the associations of pericardial adipose tissue and visceral adipose tissue volumes across quintiles of added sugar and across quintiles of sugar-sweetened beverage intakes adjusted for potential confounding factors. In a multivariable model, pericardial adipose tissue volume was higher across increasing quintiles of added sugar and sugar-sweetened beverage intakes (ptrend = 0.001 and ptrend < 0.001, respectively). A similar relation was observed for visceral adipose tissue (ptrend < 0.001 for both added sugar and sugar-sweetened beverages). CONCLUSIONS: Long-term intakes of added sugar and sugar-sweetened beverages were associated with higher pericardial adipose tissue, visceral adipose tissue, and subcutaneous adipose tissue volumes. Because these ectopic fat depots are associated with greater risk of disease incidence, these findings support limiting intakes of added sugar and sugar-sweetened beverages.
