Healthy U.S.-style dietary patterns can be modified to provide increased energy from protein.

BACKGROUND: Dietary patterns developed by the USDA provide modest levels of protein (14-18% energy) within the Acceptable Macronutrient Distribution Range (AMDR) of 10-35% for adults, though diets providing a higher percentage of energy may be beneficial for some individuals. The purpose of this study was to determine if it is feasible to modify the Healthy U.S.-Style Eating Pattern ("HEP") to provide a higher percentage of energy from protein. METHODS: Using the framework implemented by the USDA in developing the HEP, energy from protein was set at 20%, 25%, and 30%. Amounts of protein foods were proportionally increased while amounts of other foods were adjusted iteratively within specified parameters. The models also disaggregated total meat/poultry into fresh and processed forms to develop patterns maintaining current proportions, current levels, reduced, or no processed meat/poultry. Nutrient intakes were compared with nutrient goals for representative U.S. populations with 2,000 kcal needs (females 19-30 years, males 51-70 years), with 90% of the Recommended Dietary Allowance or Adequate Intake regarded as sufficient. RESULTS: Dietary patterns with 20% energy from protein were constructed with minor deviations from the current 2,000 kcal HEP. Dietary patterns with 25% energy from protein were constructed for all levels of processed meat/poultry excluding the current proportion model, though relative to the current HEP the constructed patterns reflect substantial reductions in amounts of refined grains and starchy vegetables, and substantial increases in protein foods consumed as beans and peas, seafood, and soy products. It was not possible to develop a pattern with 30% energy from protein without reducing the percentage of energy from carbohydrate below the AMDR or non-compliance with other modeling constraints. Stepwise reductions in processed meat/poultry reduced sodium intake. CONCLUSIONS: It is feasible to develop dietary patterns in a 2,000 kcal diet while mirroring the HEP that meet recommended intakes of nutrients with 20% or 25% energy from protein, though the pattern with 25% energy from protein may be more idealistic than realistic. Reduced levels of processed meat/poultry may translate to lower sodium intake.

Adequacy of total usual micronutrient intakes among pregnant women in the United States by level of dairy consumption, NHANES 2003-2016.

Background: Dairy products are a rich source of nutrients of public health concern, though most women do not meet the recommended intake of 3 cup-eq/day. Aim: The objective of this analysis was to examine micronutrient adequacy among pregnant women in the US by level of dairy consumption. Methods: Pregnant women (n = 791) ages 20-44 years in NHANES 2003-2016 were categorized by level of dairy consumption (<1, 1 to <2, 2 to <3, and ≥3 cup-eq/day). Usual micronutrient intakes and prevalence of intakes below the Estimated Average Requirement (EAR) or above the Adequate Intake level (AI) were calculated from food alone and food plus dietary supplements using the National Cancer Institute method. Diet quality was assessed with the Healthy Eating Index 2015 (HEI-2015). Results: Pregnant women consuming ≥3 cup-eq/day of dairy were more likely to meet the potassium AI than women consuming lower levels. Compared to women consuming ≥3 cup-eq/day of dairy, women consuming <1 or 1 to <2 cup-eq/day were more likely to have inadequate intake of vitamin D, magnesium, zinc, and vitamin A from foods plus supplements. Compared to women consuming ≥3 cup-eq/day of dairy, women consuming <1 cup-eq/day were more likely to have inadequate intake of calcium and riboflavin. The median urinary iodine concentration (UIC) among pregnant women consuming ≥3 cup-eq/day of dairy was 220 ng/mL compared with median UICs of 98-135 mg/mL among women consuming the lowest levels. Pregnant women consuming ≥3 cup-eq/day of dairy had the highest intake of sodium (mg/day) and saturated fat intake evaluated as a HEI-2015 component. Conclusions: Consumption of recommended levels of dairy products may help pregnant women achieve adequate intakes of select micronutrients.

Frequency of fruit juice consumption and association with nutrient intakes among Canadians.

BACKGROUND: In Canada, studies on consumption of 100% fruit juice and nutrient intakes are limited. AIM: This study aimed to evaluate nutrient intakes and adequacy of intake by frequency of fruit juice consumption. METHODS: Individuals ≥1 year (n = 34,351) participating in the Canadian Community Health Survey, 2004 with a 24-hour dietary recall and reported usual frequency of fruit juice consumption (assumed to be 100% juice) were categorized by frequency of consumption as <0.5, ≥0.5 to <1.5, or ≥1.5 times/day. RESULTS: More frequent consumption of fruit juice (≥0.5 times/day) was associated with higher intakes of total fruits and vegetables, whole fruits, energy, total sugars, vitamin C and potassium. More frequent consumption of fruit juice was associated with improved intake adequacy of vitamin C for adults. CONCLUSIONS: Fruit juice consumption contributes to increased intakes of vitamin C and potassium as well as energy and total sugars, thus presenting a trade-off for consumers to balance.

Reduction in Dietary Acrylamide Exposure-Impact of Potatoes with Low Acrylamide Potential.

Acrylamide forms primarily from a reaction between reducing sugars (e.g., glucose and fructose) and an amino acid (asparagine, Asn) formed naturally in foods, including potatoes. This reaction occurs when carbohydrate-rich foods are heated at temperatures above 120 °C. Multiple potato varieties were transformed with potato genomic DNA that results in down-regulation of the expression of the asparagine synthetase-1 gene (Asn1), significantly reducing synthesis of free Asn, and consequently lowering the potential to form acrylamide during cooking. These potatoes with low acrylamide potential (LAP) were tested in agronomic trials, and processed into French fries and potato chips. Decreased levels of acrylamide were measured in these cooked food products when derived from LAP potatoes compared with those derived from conventional potatoes. These reductions can be directly attributed to reduction in Asn levels in the LAP potatoes. The corresponding average reduction in exposure to acrylamide from French fry and potato chip consumption is estimated to be 65%, which would amount to approximately a 25% reduction in overall dietary exposure. Considering that children consume nearly three times more acrylamide than adults on a per kg body weight basis, they would experience the most impact from the reduced acrylamide associated with LAP potatoes. The potential public health impacts, in context of dietary acrylamide exposure reduction, are discussed in this study.

Daily intake of dairy products in Brazil and contributions to nutrient intakes: a cross-sectional study.

OBJECTIVE: Dairy products are sources of protein and micronutrients important in a healthy diet. The purpose of the present analysis was to estimate consumption of dairy products by Brazilians and identify contributions of dairy products to nutrient intakes. DESIGN: Dairy consumption data were obtained from 24 h dietary records. Dairy products were defined as milk (including flavoured), cheese and yoghurt. Estimates of dairy product intakes were generated for all individuals, individuals in urban and rural households and for age groups 10-18 years, 19-59 years and ≥60 years. Contributions to nutrient intakes were estimated for the total sample and sub-populations. SETTING: Nationwide cross-sectional survey, 2008-2009. SUBJECTS: Nationally representative sample of individuals aged ≥10 years in the Individual Food Intake survey, a component of the Brazilian Household Budget Survey (n 34 003). RESULTS: Among individuals aged ≥10 years, per capita intake of dairy products was 142 (se 2.1) g/d. Dairy product intake was higher among individuals in urban compared with rural areas and among groups 10-18 years and ≥60 years compared with adults aged 19-59 years. Dairy products accounted for 6.1% of daily energy intake, 7.3% of protein, 16.9% of saturated fat, 11.1% and 4.3% of total and added sugars, respectively, and 10.2-37.9% of daily Ca, vitamin D, P, vitamin A and K. CONCLUSIONS: Dairy products were substantial contributors to daily intakes of selected nutrients of concern in Brazil, although mean daily dairy product consumption was less than a typical portion. Education efforts in Brazil to raise awareness about the nutritional role of dairy foods may serve to improve overall diet quality.

Chemistry, manufacturing and exposure assessments to support generally recognized as safe (GRAS) determinations.

Identity, stability, purity, intended use levels in what foods and technical effects, and probable intake are among the key components in an assessment to support GRAS determinations. The specifications of identity of a food substance are an important component of the safety assessment as changes in the physical and chemical properties of a food substance can influence its technical effect in food and can influence its nutritional or toxicological properties of the food substance. Estimating exposure is a key determining step in the safety evaluation of a food substance. Intake assessment in GRAS determination is necessarily comprehensive based on cumulative exposure, i.e. proposed new uses plus background dietary exposure. Intake estimates for safety assurance in a GRAS determination also represent conservative overestimate of chronic exposure as they are based on 2-day average daily intake and the upper percentile (90th) intake among consumers. In contrast, in a nutrient assessment where realistic intake estimates are of interest, usual intake estimates are relied upon. It should also be noted that intake estimates for GRAS determinations are also more conservative than estimate of dietary exposure by EPA (FIFRA), where mean per capita are used to assess chronic exposure. Overall, for safety assurance, intake assessments in GRAS determinations are comprehensively cumulative and typically conservative overestimate of exposures.

Partitioning of Dietary Metal Intake--A Metal Dietary Exposure Screening Tool.

Detection of heavy metals at trace or higher levels in foods and food ingredients is not unexpected given the widespread unavoidable presence of several metals in nature, coupled with advancement in analytical methods and lowering limits of detection. To assist risk managers with a rapid risk assessment when facing these situations, a metal dietary exposure screening tool (MDEST) was developed. The tool uses food intake rates based on the National Health and Nutrition Examination Survey 2005-2010 consumption data for the U.S. population two+ years and up and for infants age six months to

Global assessment of select phytonutrient intakes by level of fruit and vegetable consumption.

Despite dietary recommendations that have repeatedly underscored the importance of increasing consumption of fruits and vegetables, intakes worldwide are lower than recommended levels. Consequently, the diets of many individuals may be lacking in nutrients and phytonutrients typical of a diet rich in a variety of fruits and vegetables. In the present study, we estimated phytonutrient intakes by adults categorised by sex, level of fruit and vegetable consumption (< 5 v. ≥ 5 servings/d), and geographic diet cluster. Intakes of nine select phytonutrients were estimated from the 2002-4 World Health Survey fruit and vegetable servings intake data (n 198,637), the FAO supply utilisation accounts data, and phytonutrient concentration data obtained from the US Department of Agriculture databases and the published literature. Percentage contributions to each phytonutrient intake from fruit and vegetable sources were also estimated. Estimated intakes of phytonutrients from fruits and vegetables varied across the thirteen geographic diet clusters, reflecting regional differences in both numbers and proportions of fruit and vegetable servings consumed, and the specific types of fruits and vegetables available in the diet. The mean phytonutrient intakes by adults consuming ≥ 5 servings/d of fruits and vegetables were approximately 2- to 6-fold the mean phytonutrient intakes by adults with low fruit and vegetable consumption (< 5 servings/d). In some cases, phytonutrient intakes by adults consuming ≥ 5 servings/d of fruits and vegetables in one geographic diet cluster were lower than the intakes by adults reporting < 5 servings/d in another cluster. The findings from this assessment provide important information regarding the major dietary patterns of phytonutrient intakes across geographic diet clusters.

Revising the daily values may affect food fortification and in turn nutrient intake adequacy.

The Nutrition Facts panel on food labels in the United States currently displays Daily Values (DVs) that are based on outdated RDAs. The FDA has indicated that it plans to update the DVs based on the newer Dietary Reference Intakes (DRIs), but there is controversy regarding the best method for calculating new DVs from the DRIs. To better understand the implications of DV revisions, assuming that manufacturers choose to maintain current label claims for micronutrients from voluntarily fortified foods, we modeled intake of 8 micronutrients using NHANES 2007-2008 data and 2 potential methods for calculating DVs: the population-weighted Estimated Average Requirement (EAR) and the population-coverage RDA. In each scenario, levels of fortified nutrients were adjusted to maintain the current %DV. Usual nutrient intakes and percentages with usual intakes less than the EAR were estimated for the U.S. population and subpopulations aged ≥ 4 y (n = 7976). For most nutrients, estimates of the percentage of the U.S. population with intakes below the EAR were similar regardless of whether the DV corresponded to the population-weighted EAR or the population-coverage RDA. Potential decreases were observed in adequacy of nutrients of concern for women of childbearing age, namely iron and folate (up to 9% and 3%, respectively), adequacy of calcium among children (up to 6%), and adequacy of vitamin A intakes in the total population (5%) assuming use of the population-weighted EAR compared with the population-coverage RDA for setting the DV. Results of this modeling exercise will help to inform decisions in revising the DVs.

Body weight status and cardiovascular risk factors in adults by frequency of candy consumption.

BACKGROUND: Limited information is available regarding the impact of candy consumption on health. The purpose of this study was to investigate associations between typical frequency of candy consumption and body weight status and select cardiovascular risk factors among adults in the United States. METHODS: Using data collected in the 2003-2006 National Health and Nutrition Examination Surveys (NHANES), adults were categorized as infrequent (≤ 3 eating occasions [EO]/month), moderate (> 3 EO/month and ≤ 3.5 EO/week), or frequent (> 3.5 EO/week) candy consumers based on the combined frequency of chocolate and other candy consumption over the previous 12 months. Weight and adiposity status were analyzed using logistic regression models, and blood pressure, lipids, and insulin sensitivity were analyzed using linear regression models. Models were adjusted for age, sex and race/ethnicity, and also for additional covariates with potential associations with the outcomes. Appropriate statistical weights were used to yield results generalizable to the US population. RESULTS: Frequency of candy consumption was not associated with the risk of obesity, overweight/obesity, elevated waist circumference, elevated skinfold thickness, blood pressure, low density lipoprotein (LDL) or high density lipoprotein (HDL) cholesterol, triglycerides, or insulin resistance. Increased frequency of candy consumption was associated with higher energy intakes and higher energy adjusted intakes of carbohydrates, total sugars and added sugars, total fat, saturated fatty acids and monounsaturated fatty acids (p < 0.05), and lower adjusted intakes of protein and cholesterol (p < 0.001). CONCLUSIONS: Increased frequency of candy consumption among adults in the United States was not associated with objective measures of adiposity or select cardiovascular risk factors, despite associated dietary differences. Given the cross-sectional study design, however, it cannot be concluded that candy consumption does not cause obesity or untoward levels of cardiovascular risk markers. The lack of an association between frequency of candy consumption and cardiovascular risk factors could be due to reduced intake of candy among the overweight due to dieting or a health professional's recommendations. Additionally, it is important to note that the analysis was based on frequency of candy consumption and not amount of candy consumed. Longitudinal studies are needed to confirm the lack of associations between frequency of candy consumption and cardiovascular risk factors.

Beverage Consumption Patterns among U.S. Adolescents and Adults from a New 24-h Beverage Recall Survey Compared to the National Health and Nutrition Examination Survey (NHANES) 2017-2018.

Beverages are major dietary components of the United States (U.S.) population. Understanding the current consumption pattern of beverages is an important element in supporting healthy diets. Our objective was to assess the validity of the 24-h beverage consumption recall data collected in 2021 through a self-administered online questionnaire (referred to as the American Beverage Association-Brandscapes Worldwide survey, ABA-BSW) by comparing it to the 24-h dietary recall data collected in the 2017-2018 National Health and Nutrition Examination Survey (NHANES). Summary statistics on the reported consumption amounts and consumption occasions (COs) of 13 beverage types (e.g., bottled water, carbonated soft drinks (CSD), tea, and others) by participants aged 13-64 years were compared between ABA-BSW (n = 20,553) and NHANES (n = 4437). The average daily consumption amount among consumers of all 13 beverage types combined was higher in ABA-BSW than in NHANES (1903 mL/day vs. 1704 mL/day). Within each beverage type, the average daily consumption amounts among consumers were generally lower in ABA-BSW except for CSD, plant-based drinks, and still juices and fruit-flavored drinks. Compared to NHANES, ABA-BSW participants reported consuming a wider variety of beverage groups, a higher number of COs per day, and lower consumption amounts within a given CO. Overall, beverage consumption patterns observed in ABA-BSW and NHANES were generally similar, supporting the design and implementation of the former survey. Further, the ABA-BSW data provide additional information on the within-day temporal beverage consumption patterns among adolescents and adults in the U.S. Differences in the observed consumption patterns between the surveys may be the result of various factors, including the survey implementation method, a consumption pattern shift between the survey time periods, beverage type availability, and impact of the COVID-19 pandemic on dietary patterns.

Egg consumption and CHD and stroke mortality: a prospective study of US adults.

OBJECTIVE: To evaluate the relationship between egg consumption and CHD and stroke mortality using the Third National Health and Nutrition Examination Survey 1988-1994 (NHANES III) and follow-up survey. DESIGN: A cross-sectional survey using a stratified, multi-stage probability sample was analysed, adjusting for survey design. Egg consumption was obtained from the FFQ and separated into categories of egg intake. Hazard ratios (HR) were calculated for CHD and stroke mortality using multivariate Cox regression models. SETTING: A health and nutrition survey conducted in the USA from 1988 to 1994 with follow-up through 31 December 2000. SUBJECTS: The study population included men and women who were free of CVD and had completed a FFQ at baseline. RESULTS: Multivariate models adjusting for health, lifestyle and dietary factors indicated that 'high' egg consumption (≥ 7 times/week v. <1 time/week) was not associated with significantly increased CHD mortality (HR = 1·13, 95 % CI 0·61, 2·11 (men); HR = 0·92, 95 % CI 0·27, 3·11 (women)). There was a statistically significant inverse association between 'high' egg consumption and stroke mortality among men (HR = 0·27, 95 % CI 0·10, 0·73), but the estimate was imprecise because of sparse data. We did not observe a statistically significant positive association between 'high' egg consumption and CHD or stroke mortality in analyses restricted to individuals with diabetes, but these analyses may be limited due to the small number of diabetics. CONCLUSIONS: We did not find a significant positive association between egg consumption and increased risk of mortality from CHD or stroke in the US population. These results corroborate the findings of previous studies.

Intake of low and no-calorie sweeteners (LNCS) by the Brazilian population.

Estimated intake of six low and no-calorie sweeteners (LNCS) (acesulfame potassium, aspartame, cyclamate, saccharin, steviol glycosides and sucralose) from processed foods and beverages, as well as from tabletop sweeteners uses, by the Brazilian population were derived and compared to the respective Acceptable Daily Intake (ADI). The estimates were based on dietary consumption data from a nationwide cross-sectional survey conducted by the Instituto Brasileiro de Geografia e Estatística (IBGE) in 2008-2009 and LNCS use rates and associated market share information based on data provided by Brazilian industry members. Two intake scenarios were considered: a conservative brand loyal consumer scenario that assumes all LNCS-containing foods and beverages and tabletop sweeteners contain the maximum reported LNCS concentrations (Scenario A) and a scenario representative of the general consumer population that uses a market share weighted average of the reported concentrations (Scenario B). Intake estimates were derived for the total Brazilian population (age 10 + y), and for the subpopulations of adolescents (10-18y), adults (19-59y), and older adults (60 + y). Intake of LNCS up to the 95th percentile did not exceed their respective ADI for all subpopulations considered, in either the general consumer scenario or the brand loyal scenario. Among consumers age 10 + y, the 95th percentile intakes of the various LNCS ranged from 6.8% to 54% of their respective ADI for the brand loyal scenario and from <1% to 6.0% of their respective ADIs for the general consumer scenario.

Screening level intake estimates of low and no-calorie sweeteners in Argentina, Chile, and Peru.

As obesity rates increase, several countries in Latin America have implemented strategies to curb the consumption of sugars, resulting in reformulations of products with low and no-calorie sweeteners (LNCS). The increased availability of LNCS-containing products raises concerns about the potential risk of exceeding the Acceptable Daily Intake (ADI). Information on the intake of LNCS among Latin American countries are limited by the lack of publicly available national consumption data. Using the Budget Method, screening level intake estimates of six LNCS (acesulfame potassium, aspartame, cyclamate, saccharin, steviol glycosides, and sucralose) were derived for Argentina, Chile, and Peru based on national sales data and product labels. Four tiered assessments were conducted where assumption of LNCS use ranged from the most conservative Tier 1 to the more refined yet conservative LNCS use and concentrations in subsequent tiers. The estimated intakes, applicable to the total population as well as children, were below their ADIs for all tiers. For Tier 2 where average LNCS concentrations were assumed present in all LNCS-containing products, intakes were <60% of the ADI. Estimates for the more refined tiers were comparable to published estimates based on select subpopulations in these countries, validating the approach used in this study.

Adequacy and Sources of Protein Intake among Pregnant Women in the United States, NHANES 2003-2012.

Limited information is available on protein intake and adequacy of protein intake among pregnant women. Using data from a sample of 528 pregnant women in the National Health and Nutrition Examination Surveys (NHANES) 2003-2012, usual intake of protein (g/day and g/kg body weight (bw)/day) and prevalence of intake below the Estimated Average Requirement (EAR) by trimester of pregnancy were calculated using the National Cancer Institute method. Percent contributions to protein intake by source (i.e., plant and animal, including type of animal source) were also calculated. Mean usual intake of protein was 88 ± 4.3, 82 ± 3.1, and 82 ± 2.9 g/day among women in trimester 1, 2, and 3 of pregnancy, respectively, or 1.30 ± 0.10, 1.35 ± 0.06, and 1.35 ± 0.05 g/kg bw/day, respectively. An estimated 4.5% of women in the first trimester of pregnancy consumed less protein than the EAR of 0.66 g/kg bw/day; among women in the second and third trimesters of pregnancy, 12.1% and 12.8% of women, respectively, consumed less protein than the EAR of 0.88 g/kg bw/day. Animal sources of protein accounted for approximately 66% of total protein. Findings from this study show that one in eight women in the second and third trimesters of pregnancy have inadequate intake of protein. Pregnant women should be encouraged to consume sufficient levels of protein from a variety of sources.

Tiered intake assessment for low- and no-calorie sweeteners in beverages.

A tiered intake assessment approach is presented and applied to derive the maximum potential global low- and no-calorie sweeteners (LNCS) intake estimates. The US and Uk markets served as representative for the world and the EU region, respectively, to determine the maximum potential exposure for acesulfame potassium (AceK), aspartame, saccharin, steviol glycosides, and sucralose in various subpopulations, including brand-loyal consumers. Conservative intake estimates for LNCS used in non-alcoholic beverages were calculated for the general population 2 + y, toddlers (12-35 months (US) or 18-35 months (UK)), young children 3-9 y, adolescents 10-17 y, adults 18-64 y, elderly 65-74 y, and very elderly 75 + y based on assumed uses in high beverage consumption markets, leveraging either the 2-day food consumption data from the 2013-2016 US National Health and Nutrition Examination Survey or the 4-day food consumption data from the 2008-2017 UK National Diet and Nutrition Survey Rolling Programme. Strong concordance between the refined budget method and the brand-loyal deterministic approach was shown, the latter assumes the maximum industry-reported global LNCS use level is present in 100% of non-alcoholic beverages. This study shows that safety of LNCS in beverages at proposed use levels can be supported for any geography, with all intake estimates falling below the acceptable daily intake in refined assessments. Importantly, this study shows the refined budget method to be a valid first-tier screening assessment in prioritising those LNCS that may benefit from more refined intake assessments when warranted.

Potassium chloride-based replacers: modeling effects on sodium and potassium intakes of the US population with cross-sectional data from NHANES 2015-2016 and 2009-2010.

BACKGROUND: Sodium intake in the USA exceeds recommendations. The replacement of added sodium chloride (NaCl) with potassium chloride (KCl) provides a potential strategy to reduce sodium intake. OBJECTIVE: The purpose of this study was to quantitatively estimate changes in intakes of sodium and potassium by the US population assuming use of potassium-based NaCl replacers in top dietary sodium sources. METHODS: Data collected in the What We Eat in America (WWEIA) component of the 2015-2016 and 2009-2010 NHANES were used to identify top-ranking sources of dietary sodium among the population aged 2 y and older based on contributions from food categories aligning with the FDA draft guidance for voluntary sodium reduction. Predicted nutrient intakes were estimated in models assuming total and feasible and practical (F&P) replacement of added NaCl with KCl in foods and ingredients within the top food sources of sodium. An expert elicitation was conducted to collect information on the F&P KCl replacement of added NaCl. RESULTS: Using 2015-2016 consumption data, the total replacement of added NaCl with KCl in the 18 top-ranking sources of dietary sodium results in a predicted sodium intake of 2004 mg/d from the replacement of 1406 mg/d sodium with 1870 mg/d potassium as KCl. Modeled F&P replacement predicted sodium intakes of 3117 mg/d (range of 2953 to 3255 mg/d) from the replacement of 294 mg/d sodium (155 to 457 mg/d) with 390 mg/d potassium (206 to 608 mg/d). Similar results are seen with 2009-2010 data. CONCLUSIONS: The F&P replacement of NaCl with KCl in top-ranking sources of dietary sodium modeled in this study can result in decreased sodium to a level consistent with the short-term intake goal targeted by the FDA of 3000 mg/d, with the mean potassium intake remaining in the range recommended for the apparently healthy population.

Contribution of specific dietary factors to CHD in US females.

OBJECTIVE: To estimate dietary cholesterol contribution to CHD risk among US females, relative to other dietary risk factors. DESIGN: A risk apportionment model was applied to apportion CHD risk shares among the lifestyle and dietary risk factors. SETTING: The model was implemented using relative risks from the Nurses' Health Study and data on CHD risk factors and consumption from the National Health and Nutrition Examination Survey 1999-2002. SUBJECTS: US females aged 25 years or older. RESULTS: On average, poor diet contributes 20 % of the CHD risk relative to obesity, inactivity and smoking, of which trans fat intake contributes 2.9 %, dietary cholesterol 1.5 % and 16 % is due to low consumption of nutrients, i.e. MUFA (1.5 %), PUFA (1.7 %), marine n-3 fatty acids (2.7 %), alpha-linolenic acid (1.1 %), dietary fibre (2.4 %), vitamin B6 (4.1 %), vitamin C (0.5 %) and folate (1.8 %). CONCLUSIONS: Reducing trans fat and dietary cholesterol intakes could lead to CHD reduction, but greater risk reduction may be achieved by improving intakes of heart-healthy nutrients currently deficient in US females' diets. Total diet consideration is essential in any CHD risk reduction strategy.

Tiered intake assessment for food colours.

A tiered intake assessment approach, ranging from the conservative default and refined budget method to refined dietary exposure assessments using national food consumption surveys is presented and applied to derive maximum potential global colour intake estimates. The US and UK markets served as representative for the world and the EU, respectively, to determine the maximum potential exposure ceilings for eleven colours in various sub-populations, including brand-loyal consumers. Industry-reported global use levels were assigned as the maximum level. Conservative intake assessments for food colours used in non-alcoholic beverages were estimated for the general population 2 + y, toddlers, children 3-9 y, adolescents 10-17 y, adults 18-64 y, elderly 65-74 y, very elderly 75 + y based on assumed uses in high intake markets. Refined dietary exposures were estimated using either the 2-day food consumption data from the 2013-2016 US National Health and Nutrition Examination Survey or the 4-day food consumption data from the 2008-2016 U.K. National Diet and Nutrition Survey Rolling Programme. In the most refined market-share adjusted assessment, brand-specific market volume data were used to place appropriate weight on corresponding beverage type uses. Strong concordance between the refined budget method and the brand-loyal deterministic approach was shown, in which the latter assumes that the maximum use level of the colour is present in 100% of non-alcoholic beverages. This study shows that safety of colours - both synthetic and natural - in beverages at proposed use levels can be supported for any geography, with all intake estimates falling below the acceptable daily intake in refined assessments. Importantly, this study demonstrates that the refined budget method is a valid first-tier screening assessment to prioritise food colours that may benefit from more refined intake assessments when warranted.

Health Care Costs and Savings Associated with Increased Dairy Consumption among Adults in the United States.

BACKGROUND: The purpose of this study is to estimate the impact on health care costs if United States (US) adults increased their dairy consumption to meet Dietary Guidelines for Americans (DGA) recommendations. METHODS: Risk estimates from recent meta-analyses quantifying the association between dairy consumption and health outcomes were combined with the increase in dairy consumption under two scenarios where population mean dairy intakes from the 2015-2016 What We Eat in America were increased to meet the DGA recommendations: (1) according to proportions by type as specified in US Department of Agriculture Food Intake Patterns and (2) assuming the consumption of a single dairy type. The resulting change in risk was combined with published data on annual health care costs to estimate impact on costs. Health care costs were adjusted to account for potential double counting due to overlapping comorbidities of the health outcomes included. RESULTS: Total dairy consumption among adults in the US was 1.49 cup-equivalents per day (c-eq/day), requiring an increase of 1.51 c-eq/day to meet the DGA recommendation. Annual cost savings of $12.5 billion (B) (range of $2.0B to $25.6B) were estimated based on total dairy consumption resulting from a reduction in stroke, hypertension, type 2 diabetes, and colorectal cancer and an increased risk of Parkinson's disease and prostate cancer. Similar annual cost savings were estimated for an increase in low-fat dairy consumption ($14.1B; range of $0.8B to $27.9B). Among dairy sub-types, an increase of approximately 0.5 c-eq/day of yogurt consumption alone to help meet the DGA recommendations resulted in the highest annual cost savings of $32.5B (range of $16.5B to $52.8B), mostly driven by a reduction in type 2 diabetes. CONCLUSIONS: Adoption of a dietary pattern with increased dairy consumption among adults in the US to meet DGA recommendations has the potential to provide billions of dollars in savings.
