Adult dietary patterns with increased bean consumption are associated with greater overall shortfall nutrient intakes, lower added sugar, improved weight-related outcomes and better diet quality

Background Limited evidence is available that focuses on beans within American dietary patterns and health. The purpose of this study was to identify commonly consumed adult dietary patterns that included beans and compare shortfall nutrient intakes and diet quality, relative to adults whose typical dietary pattern did not include beans. Methods The analyses used data from the National Health and Nutrition Examination Survey, 2001–2018. Cluster analysis was used to identify bean patterns of consumption, while the USDA food coding system defined daily beans consumed. Five bean dietary patterns of consumption were identified, of which four patterns included both canned beans and dry beans, while one pattern had no bean consumption. Bean consumption was defined as those consuming kidney beans, black beans, chickpeas, and/or pinto beans. Results Adults consuming Bean Dietary Patterns 1, 2, 3 and 4 had significantly higher diet quality scores (as assessed by USDA’s Healthy Eating Index-2015) compared to the no-bean pattern (61.2 ± 0.5, 58.9 ± 0.5, 55.2 ± 0.4 and 56.5 ± 0.8 vs 48.8 ± 0.2 p’s < 0.0001). Bean consumers also had significantly higher intakes of several shortfall nutrients (choline, alpha-linolenic acid, folate, iron, magnesium and vitamin E) relative to non-consumers of beans. Similarly, intake of dietary fiber, potassium and calcium, all nutrients of public health concern were significantly higher in bean patterns compared to no-beans. Bean Dietary Pattern 1 (~ 13.5% of total daily kcal from beans or ~ 2 servings of beans/day) and 2 (~ 9.5% of total daily kcal from beans or ~ 1.7 servings of beans/day) were significantly associated with lower BMI, decreased body weight and improved waist circumference relative to no-beans. Conclusions Dietary patterns that are rich in canned and dry beans were associated with significantly higher diet quality scores and greater intake of shortfall nutrients, including nutrients of public health concern. Bean dietary patterns were also associated with improved weight-related outcomes. Dietary guidance should consider the nutrient and health benefits associated with the promotion of increased canned and dry bean consumption in American dietary patterns.


Background
Dietary patterns that contribute optimal nutrition while concurrently supporting the environment and mitigating climate change is becoming increasingly relevant globally.Beans, and other protein-rich legumes are considered one of the lowest climate impacting foods via reduced greenhouse gas emissions [1], removal of carbon from the atmosphere during production and improved soil fertility through nitrogen fixation [2,3].Additionally, the inclusion of beans within American dietary patterns has routinely been recommended by current [4] and previous Dietary Guidelines for Americans (DGA) [5].Indeed, beans contribute nutrient density (i.e., provide a meaningful daily contribution as recommended by National Academies Sciences, Engineering and Medicine, Institute of Medicine's Dietary Reference Intakes; https:// nap.natio nalac ademi es.org/ catal og/ 11537/ dieta ry-refer enceintak es-the-essen tial-guide-to-nutri ent-requi remen ts) to dietary patterns, with a 100 g serving (115-164 kcal) of cooked beans contributing 5.3-10 g of dietary fiber, 111-168 mg of potassium, 83-207 mcg of folic acid, 17-70 mg of calcium, 7.7-9.3g of protein, 0.4-2.6 g of total fat, and 21-27 g of carbohydrate [6].A recent panel of experts examining the evidence surround carbohydrate food quality reported fruits, vegetables, beans and other legume products scored the highest quality carbohydrate score predominantly due to the contribution of higher dietary fiber and potassium levels and lower amounts of sugar and sodium levels [7][8][9].Beans, peas, and lentils are unique foods in that they can be considered a part of the protein foods group as well as the vegetable group.DGA has previously stated "shifts are needed within the protein foods group to add variety and selecting from the seafood subgroup or the beans, peas, and lentils subgroup more often could help meet recommendations while still ensuring adequate protein consumption" [4].Nonetheless, less than 20% of the population are at or above recommendations for bean, peas and lentil consumption [4].Beans, peas, and legumes are consumed in relatively small amounts, at an average of 0.1 cup eq/ day [10].Canned beans account for approximately 75% of units sold at US retail, outselling other forms by roughly 4:1 [11].
Previous work using NHANES 1999-2002 has shown numerous nutrient and health outcome benefits associated with both canned and dry bean consumption.In particular, adults consuming baked beans had reduced systolic blood pressure versus non-consumers, even in the presence of higher daily sodium intakes.Similarly, adults reporting consumption of a variety of beans (pinto, kidney, etc.) had greater intakes of shortfall nutrients, and improved weight-related outcomes, relative to bean non-consumers.The inclusion of both baked beans and a variety of beans in dietary patterns was associated with reduced intake of discretionary fat and added sugars [12].A recent systematic review and meta-analysis of randomized clinical trials further substantiates the health benefits stemming from bean consumption, such that beans significantly reduced LDL-cholesterol, cardiovascular disease (CVD) and coronary heart disease (CHD) risk [13].Similarly, data from a large cohort showed legume consumption four times or greater per week, was associated with significantly reduced risk for CVD and CHD in adults, leading the investigators to argue in support of increasing legume consumption as a key dietary strategy to help prevent CHD in the general population [14].Others have shown that bean consumption does not impact cardiovascular risk factors, however, the intervention period has also been questioned as being short in duration [15].
The nutrient-density of beans [16,17] and their contributions to diet quality have been documented by the most recent collaboration between the National Cancer Institute (NCI) and the United States Department of Agriculture (USDA) to update the Healthy Eating Index (HEI) diet quality scale.The sub-component of 'greens and beans' allow for a maximum score from this component when an individual has ≥ 0.2 cup equivalents per 1000 kcal and a score of zero if the dietary patten contains no dark green vegetables or legumes (i.e., beans and peas) [18].While the average diet quality has slightly improved in the last decade, scores indicate that diet quality is not aligned with DGA recommendations [4,5], yet accumulating evidence exists supporting increased fruit, legumes and vegetables and improvements in diet quality and longevity [19][20][21][22][23].
As current dietary guidance includes beans, peas, and lentils as a component of the core elements that comprises a healthy dietary pattern and includes these foods within both the vegetable and protein food groups, the purpose of the current analysis was to identify how beans are consumed within American dietary patterns and determine relationships with nutrient intakes and diet quality in adults.

Methods
The analysis used data from What We Eat in America (WWEIA), which represents the dietary intake component of NHANES.NHANES is a cross-sectional, nationally representative survey directed by the National Center for Health Statistics.NHANES samples free-living, noninstitutionalized individuals and is currently a continuous study complied by the Centers for Disease Control and Prevention (CDC) where data are released every two years [24,25].Ethical protocols, including informed consent from study participants have been previously obtained, approved and documented by the CDC ethic boards.The distribution of the US population, in addition to response rates and population totals for NHANES are summarized by the CDC [26].Data for the nutrients examined are from the U.S. Department of Agriculture (USDA) Food and Nutrient Database for Dietary Studies (FNDDS) database for NHANES [27].The FNDDS databases determine food and beverage nutrient values in WWEIA.The collection procedure for WWEIA involves use of the Automated Multiple Pass Method (AMPM), representing a dietary collection tool that provides a valid, evidence-based approach for gathering data for national dietary surveys [28,29].Although two days of recall are recorded in NHANES, the current analysis focused on 24-h recalls obtained from Day 1 which were collected via an in-person interview.Accuracy, effectiveness, and efficiency of the AMPM method has been extensively reported and previously documented [29].
Bean patterns of consumption were determined using SAS 9.4 (SAS Institute, Cary, NC, USA) PROC CLUSTER using the first day of 24-h dietary recall from NHANES 2001-2018 and appropriate population weights.The cluster analysis approach is a statistical procedure that analyses large datasets to identify various dietary patterns while maximizing differences among the dietary patterns.Cluster analysis allows for the focus on a specifically defined aspect (i.e., bean consumption) and then directs maximal differences in clusters for evaluations.For these analyses bean consumption was defined to include kidney beans (i.e., white and red), black beans, chickpeas, and pinto beans (canned and non-canned), while soybean consumption was excluded in the analysis.For the present analyses, cluster analysis allowed for group comparisons rather than factor analysis which examines associations.
USDA classifies foods into 15 main food groupings, about 45 food subgroups and over 150 separate food categories [30].For the present analyses, food groups were collapsed into the 14 WWEIA food groups (excluding the baby food group) and beans as defined by the bean definition.All food codes fit in one and only one of the food pattern groupings.The patterns identified by the cluster analysis were then identified by percent calories within each food pattern grouping (only foods that contributed 3% or more of calories were included) at the centroid of each cluster.Using this method resulted in 4 readily identifiable bean patterns (refer to Table 1).In addition, a 'no consumption' of beans group (i.e., no beans reportedly consumed throughout the 24-h reporting session) was identified, thus creating a total of 5 unique patterns of consumption for evaluation.With food patterns identified, each participant was placed into one bean pattern of consumption.The cluster definitions and the associations of subjects with a cluster were directly from the output of the cluster procedure and each subject was placed in the cluster that matched most closely to the pattern of calories across the food categories.
Means (± standard errors) for daily nutrient intakes, food group consumption, and diet quality were determined using day 1 dietary intake data.Diet quality was assessed using USDA's 2015 Healthy Eating Index (HEI) [18].HEI is a validated dietary tool that provides a measure of diet quality and conformance to US dietary guidance [18].
Covariates for analyses of nutrient/energy intake, HEI-2015 and HEI-2015 sub-components were age, gender,   ethnicity, and household poverty income ratio (PIR).PIR was grouped into three categories (< 1.25, 1.25-3.49,and > 3.49) and was based the US federally established poverty criteria, thus a PIR of < 1.25 equated to below 125% of poverty level, while higher values represented the subject was from a household with higher income status.Nutrient and food group intakes were adjusted for covariates mentioned above, but also for energy intakes.
The main comparison of interest was to compare results between the various bean patterns of consumption identified and the no bean consumption dietary pattern group.A p-value of ≤ 0.05 was used to determine statistical significance in the current analysis.

Bean patterns of consumption in adults
Four bean foods patterns of consumption (i.e., clusters) were identified in the present analysis, one of which included adults who did not consume any beans during the first dietary recall.Table 1 lists bean patterns isolated in adults, with the highest bean consumption seen in Bean Dietary Pattern 1 (13.5% of daily calories stemming from beans) and the lowest bean consumption seen in Dietary Pattern 3 (9.3% of daily calories originating from beans).Bean Dietary Pattern 4 had the greatest contribution of calories (36.6% of daily calories) stemming from sweets/snacks (i.e., cakes, cookies, pies, doughnuts, potato chips, candy, etc.), while Bean Dietary Pattern 3 had 36.7% of all calories derived from mixed dishes-a category which includes mixed meals (i.e., Mexican burrito and taco dishes, Asian fried rice, pizza, hamburgers, hot dogs, cold cut sandwiches, macaroni and cheese, etc.), which have been known to contribute greater amounts of sodium and saturated fat.Bean Dietary Pattern 1 and 2 had the largest caloric contributions from vegetables, (5.8% of total daily calories).

Nutrient and energy intake within bean patterns of consumption
Mean energy and nutrient intakes are summarized in Table 2. Daily energy intake was higher in 3 of the 4 bean patterns relative to the no beans pattern, however, numerous statistically significant and favorable outcomes were observed both in macro-and micronutrient intakes after adjusting for energy intake.While overall carbohydrate intake was elevated in 3 of the 4 bean patterns of consumption, added and total sugars were significantly lower in Bean Dietary Pattern 2 and 3 compared to the no bean pattern.Added and total sugars were signficantly greater in Bean Dietary Pattern 4, likely due to the greater consumption of sweets and snacks in this group (see Table 1).Daily protein intake was significantly greater in two of the bean clusters and daily total and saturated fat intake was higher in three of the bean clusters when compared to the no bean group.Adults in Bean Dietary Pattern 1, which represented the bean cluster with the greatest calories sourced from beans, had significantly lower total fat and saturated fat intake relative to the no bean cluster.Total monounsaturated and polyunsaturated fatty acids were significantly elevated in 3 of the 4 bean patterns of consumption compared to no beans.When considering dietary fiber and potassium, both identified as public health nutrients of concern by DGA, both nutrients were substantially higher in all four bean deiatry patterns compared the dietary pattern that excluded beans.Other shortfall nutrients, including magnesium, folate DFE, iron and vitamin E, were significantly higher in several dietary patterns that included beans when compared to the dietary patterns without daily bean intake.While no signifiant differences were observed between Bean Dietary Pattern 1 and the no bean pattern, the remaining bean patterns of consumption all showed elevated daily sodium relative to the no bean pattern.Total choline, while underconsumed in the US population, was significantly higher in adults consuming Bean Dietary Pattern 1, 2 and 3 in comparison to adults in the no bean pattern of consumption.

Diet quality scores within bean patterns of consumption
Table 3 provides a measure of diet quality scores, as measured by HEI-2015, within each bean pattern of consumption identified and compares all bean patterns to the no bean pattern of consumption.All bean dietary patterns idenified showed significantly higher total diet quality scores compared to the no bean dietary pattern of consumption.Moreover, adults in all four bean dietary patterns consumed significantly greater amounts of total vegetables, greens and beans, seafood, and plant proteins.Participants in Bean Dietary Pattern 1 and 2 consumed greater amounts of total frut and whole fruit in comparison to the no bean dietary pattern, as indicated by the higher scores in these food categories.Adults in Bean Dietary Pattern 1, 2, and 3 consumed greater quanities of whole grain relative to the no bean group.Adults consuming Bean Dietary Pattern 1, 2, and 4 showed improved fatty acid ratios, which considered levels of polyunsaturated fatty acids (PUFAs), monounsaturated fatty acids (MUFAs) and saturated fatty acids (SFAs) when compared to the no bean group (standard for maximum score [PUFAs + MUFAs/SFAs] ≥ 2.5; standard for minimum score of zero [PUFAs + MUFAs/SFAs] ≤ 1.2).
When considering nutrients or food groups to moderate, added sugar scores (standard for maximum score ≤ 6.5% of energy; standard for minimum score of zero ≥ 26% of energy) were significantly better in 3 of the 4 bean patterns of consumption (Dietary Pattern 1, 2, and 3) relative to the no-bean group, while Bean Dietary Pattern 4 had a higher added sugar contribution, likely due to the large added sugar contribution from sweets and snacks (see Table 1).Saturated fat contribution from 3 of the 4 bean patterns of consumption was greater (standard for maximum score ≤ 8% of energy; standard for minimum score of zero ≥ 16% of energy) versus the no bean group, while Bean Dietary Pattern 3 was not statistically different from the no bean group.Refined grains (standard for maximum score ≤ 1.8 oz equivalents per 1,000 kcal; standard for minimum score of zero ≥ 4.3 oz equivalents per 1,000 kcal) provided significantly less energy in Bean Dietary Pattern 2 and 4, while Bean Dietary Pattern 3 contributed a greater amount of refined grains relative to the no bean group.Sodium scores (standard for maximum score ≤ 1.1 g per 1,000 kcal; standard for minimum score of zero ≥ 2.0 grams1,000 kcal) were poorer in Bean Dietary Pattern 3 and improved in Bean Dietary Pattern 4 compared to the no bean group.

Fruit, vegetables, grain and fat intake within bean patterns of consumption
The mean intake of various FPED food groups within the dietary patterns of consumption identified are summarized in Table 4.Total fruit consumption was 30% higher in the greatest bean consumption pattern (Bean Dietary Pattern 1) relative to the no bean group (1.3 ± 0.06 vs. 1.0 ± 0.02 cup equivalents; p < 0.0001).Adults consuming Bean Dietary Pattern 2 had lower total fruit consumption versus the no bean group.Total   1).

Discussion
Several bean dietary patterns of consumption in US adults were associated with favorable nutrient intakes.Bean consumers showed higher intakes of several shortfall nutrients (choline, alpha-linolenic acid, folate, iron, magnesium and vitamin E) relative to no bean consumption.Similarly, intake of dietary fiber, potassium and calcium, all nutrients of public health concern were significantly elevated in bean patterns relative to avoiding beans in dietary patterns.Two of the bean-rich dietary patterns were also significantly associated with improved weight-related measures, such that adults consuming Bean Dietary Pattern 1 and 2 had lower BMIs (-0.8 kg/m 2 and kg/m 2 , respectively), reduced body weight (-2.5 kg and -2.0 kg, respectively) and smaller waist circumferences (-2.3 cm and -1.7 cm) in comparison to adults in the no-bean group.Dietary patterns that are rich in beans were associated with significantly higher diet quality scores, predominantly due to elevated scores from food groups encouraged by DGA, including total vegetables, greens and beans, seafood, and plant proteins.The current findings suggest that avoiding beans within dietary patterns may lead to nutrient and public health consequences in adults.Upcoming dietary guidance should consider the health benefits associated with the promotion of increased bean consumption in dietary patterns and develop strategies to encourage increased consumption in American adults.The current analysis is aligned with a previous study using data from NHANES 1999-2002, where various types of canned and dry bean consumption were associated with improved nutrient intakes and favorable health outcomes [12].Shared findings between the various groups of bean consumers showed that irrespective of the type of beans consumed, bean consumption was associated with greater dietary fiber and potassium intakes versus non-bean consumption.When considering baked beans, a very popular form of bean consumption in American dietary patterns, adult consumers had higher intakes of several shortfall nutrients, including dietary fiber, potassium, magnesium, and iron compared to bean non-consumers.Further, adult baked bean consumers had significantly lower systolic blood pressure versus non-consumers, concurrent to greater sodium intake.In the same analysis, adults consuming a variety of beans (i.e., pinto bean, kidney beans, etc.) also had higher intakes of dietary fiber, potassium, magnesium, iron, and total folate in comparison to non-consumers.Adults consuming a variety of beans showed lowered body weights, reduced waist circumferences and a 29% lower risk of having an elevated waist circumference compared to non-consumers.When consumption of baked beans and variety beans were combined in the analysis, adult consumers had a 23% lowered risk of increased waist circumference and a 22% reduced risk of having obesity relative on non-consumers [12].
The current work consistently showed that all beaninclusive dietary patterns were associated with higher diet quality scores relative to non-bean consumption, as much as 25% higher.This finding is consistent with evidence presented in the 2020 DGAC.Specifically, higher diet quality scores have been documented among Asian Americans predominantly propelled by higher intakes of fruits, vegetables, greens and beans concurrent to reduced added sugar and saturated fat intake [1].Diet quality has consistently been reported as a key component of health outcomes, quality of life and longevity.For instance, a recent review described strong substantiation stemming from prospective cohort trials where higher diet quality scores were related to a 14-29% reduced risk of cardiovascular disease and 0.5-2.2 years greater cardiovascular-free survival time [31].Similarly, evidence from the Women's Health Initiative Observational Cohort Study demonstrated 23% reduced cardiovascular disease risk and 30% lowered risk of heart failure in individuals with the greatest diet quality scores [32].Data from nearly 39,000 men in the Health Professional's Follow-Up Study cohort and 68,000 women from the Nurses' Health Study cohort demonstrated significant multivariate risk reductions related to diet quality scores, such that improved diet quality (i.e., higher diet quality scores) was associated with 39% and 19% decreased risk of cardiovascular disease in men and women, respectively [33].Similarly, another analysis using data from Health Professional's Follow-Up Study cohort and the Nurses' Health Study found participants in the top diet quality score quintile had an overall 19% lowered risk for major chronic disease.Further, the investigators showed the highest diet quality score quintile to be associated with 24% decreased risk of cardiovascular disease, 31% reduced risk for coronary heart disease, 20% lowered risk for stroke, 23% decreased risk for diabetes, and 6% reduced risk for cancer [33].Likewise, the Mediterranean Diet Score, which encompasses high consumption of legumes amongst other components, found that higher scores were related to significant reductions in all-cause, coronary heart disease and cancer mortality rates in a Greek cohort of approximately 22,000 men and women.Indeed, a greater adherence to a Mediterranean diet was associated with 25%, 33% and 24% reduced risk of all-cause, coronary heart disease and cancer mortality, respectively [34].The Global Burden of Disease Study [35] recently further emphasized the prominence of diet quality and associations to cardiovascular disease-related mortality outcomes.In particular, of thirteen dietary risk factors examined for cardiovascular disease mortality risk, only a high sodium consumption, a low intake of whole grains and reduced intake of legumes contributed significantly to age-adjusted mortality and disabilityadjusted life years, leading the investigators to recommend reducing sodium, and increasing consumption of whole grains and legumes as the top global priority to improve diet quality and significantly reduce cardiovascular disease burden [35].The relationship between diet quality and chronic disease outcomes is evident with the revisions and updating of the HEI-2015 scale via collaborations involving the USDA and the National Cancer Institute [18].While the majority of the dietary components were unaltered, a major amendment involved the procedure by which legumes were assigned to the food components of the HEI scale.Specifically, in HEI-2015, which represents the most recent version of the diet quality scale, legumes are distributed to four of the thirteen components of which includes 'Total Protein Foods' , seafood and Plant Proteins, 'Total Vegetables' , and 'Greens and Beans' [18].
DGA 2020 advocates that Americans consume below 2300 mg/day of sodium as part of a healthy dietary pattern [4].Nevertheless, approximately 9 in 10 Americans ≥ 2 years-old consume excessive levels of sodium daily [36], with average sodium intakes being greater than 3400 mg per day [37].In the present analysis, while sodium levels were higher in three bean dietary patterns of consumption, relative to the nobean group, potassium intake levels were significantly higher in all bean patterns of consumption examined.An important, and often missed principle, involves potassium intakes when assessing sodium intakes in the American population.When the US Congress asked the CDC to assess and review the Dietary Reference Intakes for sodium, the CDC decided to combine sodium and potassium into one assessment given the clear and established interrelationship of the two nutrients and the evident role sodium and potassium contribute to public health [38].The American Heart Association has previously stated "foods with potassium can help control blood pressure by blunting the effects of sodium and the more potassium you eat, the more sodium you process out of the body.Potassium also helps relax blood vessels, which helps lower blood pressure" [39,40].It is also important to note that higher sodium contributions in Bean Dietary Pattern 2, 3 and 4 were likely contributed from the greater intake of sweets/snacks and mixed dishes (see Table 1).In addition, canned beans can contribute greater sodium, however, a substantial amount of sodium can be eliminated via draining the brine and rinsing the beans prior to consumption.Nonetheless, as it has been documented that Americans consume greater amounts of canned beans vs. dry beans [11], it is logical to assume that the present positive nutritional findings, as well as NHANES-based results from previously published data [12], are driven to a substantial extent from canned bean consumption, irrespective of sodium levels.Indeed, other researchers using NHANES datasets highlighted the nutritional benefits of including both dried beans and drained canned beans as a strategy to promote healthy dietary patterns [41].Future research should consider bean patterns of consumption and various health outcomes, including blood pressure and cardiovascular outcomes that have been linked to sodium intake.
Limitations with NHANES datasets have been previously reported [42][43][44].Nutrient intake and diet quality data are obtained from 24-h dietary recalls, which rely on study participant memory.While validated procedures are used to collect the data, recalled information may be inaccurate and biased from misreporting or memory challenges [45,46].In addition, the current evidence, being observational, cannot establish a causal link between the different bean dietary patterns examined and improvements in nutrient intakes and diet quality.However, a significant and robust advantage of the current work stems from the use of NHANES, which is a large continuous survey that examines a nationally representative sample of about 5,000 individuals yearly by highlytrained medical personnel [29].Additionally, numerous covariates were used to adjust the data in an attempt to remove potential confounding scenarios.For the diet quality analysis, the simple algorithm and code available to the public was used in the analysis, and day-to-day variability may pose as a limitation, however, the large sample size of the current analysis helps mitigate this issue.

Conclusions
The present analyses demonstrated favorable associations with bean consumption, shortfall nutrient intakes, weight outcomes, and diet quality.Adults consuming bean dietary patterns had higher intakes of several shortfall nutrients compared to no bean consumption, and greater intake of dietary fiber, potassium and calcium, all nutrients of public health concern.Two of the bean dietary patterns identified were further associated with significant improvements in weight-related measures, including BMI, body weight and waist circumference, relative to dietary patterns with no beans.All bean dietary patterns of consumption were associated with significantly higher diet quality scores, predominantly due to elevated scores from food groups encouraged by DGA, including total vegetables, greens and beans, seafood, and plant proteins.The avoidance of beans within dietary patterns may exacerbate current nutrient shortfalls and may even lead to nutrient and public health consequences in adults.Dietary strategies involving the promotion of increased canned and dry bean consumption within dietary patterns may prove to have numerous public health benefits for American adults.
