Daily polyphenol intake in France from fruit and vegetables

The objective of this study was to create a French database on the polyphenol content of fruit and vegetables as uncooked fruits and vegetables and then to evaluate polyphenol intake through fruit and vegetable consumption in France. To achieve this, we used the Folin-Ciocalteu method adapted to fruit and vegetable polyphenol quantitation (1). Vegetables with the highest polyphenol concentration were artichokes, parsley, and brussels sprouts [>250 mg of gallic acid equivalent (GAE)/100 g fresh edible portion (FEP)]; fruits with the highest concentrations were strawberries, lychees, and grapes (>180 mg of GAE/100 g FEP). Conversely, melons (Cantaloupe cv.) and avocados had the lowest polyphenol concentration for fruits and vegetables, respectively. Based on fruit consumption data, apples and strawberries are the main sources of polyphenols in the French diet, whereas potatoes, lettuces, and onions are the most important vegetable sources. Total polyphenol intake from fruit is about 3 times higher than from vegetables, due to the lower polyphenol concentration in vegetables. The calculation of polyphenol intake, based on both assessment methods used [(Société d'Etudes de la Communication, Distribution et Publicité (SECODIP) and Supplémentation en Vitamines et Minéraux Antioxydants (SUVIMAX)], showed that apples and potatoes provide approximatively half of the total polyphenol intake from fruit and vegetables in the French diet.     

Increasing antioxidant intake from fruits and vegetables: practical strategies for the Scottish population

Background Increasing intakes of dietary antioxidants may help to reduce oxidative damage caused by free radicals and provide protection against the progression of a number of chronic diseases. The present study aimed to estimate the antioxidant intake from fruits and vegetables in the UK and Scottish population and to examine consumption models to identify potential strategies to optimize antioxidant intake from these foods. Methods This was a retrospective study of cross‐sectional data on fruit and vegetable intake in relation to antioxidant intake. Antioxidant capacity of individual fruits and vegetables was determined by the ferric reducing antioxidant power assay and data on quantity and frequency of consumption of fruits and vegetables determined from National Diet and Nutrition Survey 2000–2001. Results Mean antioxidant intake in UK population from fruits and vegetables varied by region. In the Scottish sample (n = 123), mean antioxidant intake was estimated at 680 ± 689 μmol day^?1 with 92% subjects consuming <400 g of fruits and vegetables per day. Consumption data showed that strawberries, apples, orange citrus fruits, purple broccoli and cauliflower were the top five sources of antioxidants from fruits and vegetables in the Scottish population. Conclusions Appropriate selection of fruits and vegetables would help to achieve a higher antioxidant intake with the potential to produce significant health benefits.     

Consumption of Dried Fruits Is Associated with Greater Intakes of Underconsumed Nutrients,Higher Total Energy Intakes,and Better Diet Quality in US Adults: A Cross-Sectional Analysis of the National Health and Nutrition Examination Survey, 2007-2016

BackgroundDried fruits are shelf-stable alternatives to fresh fruit that avert common barriers to consuming fruit. Consumption of dried fruits may facilitate greater fruit consumption and contribute to better diet quality and nutrient intakes.ObjectiveOur aims were to assess differences in diet quality and cardiometabolic health between dried fruit consumers and nonconsumers, and evaluate differences in nutrient intakes on days when dried fruits were consumed vs not consumed.DesignThis is a cross-sectional analysis of data from the National Health and Nutrition Examination Survey 2007-2016.Participants/settingMean dried fruit intakes were estimated in adults 20 years and older (n = 25,590) who completed a dietary recall. Dried fruit consumers (one-quarter cup-equivalent/day or more) were defined in respondents with 2 complete dietary recalls (n = 22,311). Within-person differences in nutrient intakes were assessed in respondents who consumed dried fruit on 1 of 2 dietary recalls (n = 1,233).Main outcome measuresCardiometabolic risk factors, diet quality scored using the Healthy Eating Index 2015, and nutrient intakes were assessed.Statistical analysesDiet quality and cardiometabolic health were compared in consumers vs nonconsumers using multivariate linear regression, adjusted for demographic and lifestyle factors. Within-person differences in nutrient intakes on days when dried fruits were consumed vs not were assessed using multivariate linear regression.ResultsMean ± standard error dried fruit intake was 0.04 ± 0.001 cup-equivalents and represented 3.7% of total fruit consumed. Consumers (7.2% of adults) had higher quality diets than nonconsumers (mean ± standard error Healthy Eating Index 2015 score = 60.6 ± 0.5 vs 52.6 ± 0.3; P < 0.001) and lower mean body mass index, waist circumference, and systolic blood pressure (P < 0.01). Total carbohydrate, dietary fiber, potassium, and polyunsaturated fat intakes were greater on days when dried fruits were consumed vs not consumed (P < 0.001). Total calorie intakes were also greater (208-215 kcal; P ≤ 0.002) when dried fruits were consumed.ConclusionsDried fruit consumption is associated with higher diet quality and greater intakes of underconsumed nutrients. However, dried fruits do not appear to displace other calorie sources on days when consumed.     

Kinder sollten mehr Obst und Gemüse essen

A diet rich in fruits and vegetables in schoolchildren is important for the physical and cognitive development of the child as well as for the prevention of nutrition-related diseases. In Germany, 816?schoolchildren (boys and girls, aged 10-13?years) from 14?public schools in the central region of Hesse were asked about their fruit and vegetable intake in May?2009. The results show that the mean fruit intake is 185?g fruit per day and 83?g vegetables per day in all schoolchildren. There is no significant difference in the amounts of fruit consumed by boys and girls. Regarding the amounts of consumed vegetables, there is a significant difference between gender (p?=?0.004). Schoolchildren eat fruits more frequently than vegetables. Furthermore, they prefer sweet fruits and convenient vegetables. German schoolchildren still do not reach national recommendations for fruit and vegetable intake, although current results show slightly equal or rather lower intake levels for fruits, but not for vegetables, in comparison to other national studies (e.g., National Consumption Study II, Donald Study, and EsKiMo Study). Health-promotion strategies should focus on both fruit and vegetable consumption to ensure a large variety of food choices and nutrient intake.     

Fruit and vegetable consumption among high school students--United States, 2010

A diet high in fruits and vegetables is associated with a decreased risk for many chronic diseases and some cancers, and can aid in weight management. Current daily fruit and vegetable recommendations for adolescents who participate in <30 minutes of physical activity daily are 1.5 cups of fruit and 2.5 cups of vegetables for females and 2 cups of fruit and 3 cups of vegetables for males (1 cup is approximately equal to one medium apple, eight strawberries, 12 baby carrots, or one large tomato). However, recently published data from the National Health and Nutrition Examination Survey 2003-2004 revealed that consumption was considerably below these levels. To assess fruit and vegetable consumption among high school students, CDC analyzed data from the 2010 National Youth Physical Activity and Nutrition Study (NYPANS). This report describes the results of that analysis, which indicated that, in 2010, the median number of times per day that high school students consumed fruits and vegetables was 1.2 for both. For vegetables, the median number of times per day was lower for non-Hispanic black students (1.0) and Hispanic students (1.1) than non-Hispanic white students (1.4). Overall, 28.5% of high school students consumed fruit <1 time daily, and 33.2% of high school students consumed vegetables <1 time daily. The infrequent fruit and vegetable consumption by high school students highlights the need for effective strategies to increase consumption. Policy and environmental approaches to provide greater access to and availability of fruits and vegetables are among the strategies that schools and communities might choose to achieve this goal.     

Assessment of fruit and vegetable intake among the population of junior high school students from Oleśnica

The aim of this study was to assess fruit and vegetable intake among the population of junior high school students. 113 students from Junior High School No. 2 in Ole?nica participated in the research. In order to assess the intake of fruit and vegetables, the method of food frequency questionnaire was used. It was stated that vegetables appearing most frequently in the diet of girls were: tomatoes, carrots, cucumbers and fresh vegetable salads, and in the meals of boys were: tomatoes, fresh vegetable salads, cucumbers and vegetable salads. Boys and girls declared that the most often consumed fruits were: apples, oranges, mandarins and bananas. The mean daily total consumption of fruit and vegetables by the junior high school students was 358.5 g/day. Compared with current dietary recommendations, intakes of fruit and vegetables were too low.     

Low intake of fruits,berries and vegetables is associated with excess mortality in men: the Kuopio Ischaemic Heart Disease Risk Factor (KIHD) Study

Diets rich in fruits and vegetables have been of interest because of their potential health benefits against chronic diseases such as cardiovascular disease (CVD) and cancer. The aim of this work was to assess the association of the dietary intake of a food group that includes fruits, berries and vegetables with all-cause, CVD-related and non-CVD-related mortality. The subjects were Finnish men aged 42-60 y examined in 1984-1989 in the prospective Kuopio Ischaemic Heart Disease Risk Factor (KIHD) Study. Dietary intakes were assessed by 4-d food intake record during the baseline phase of the KIHD Study. The risk of all-cause and non-CVD-related deaths was studied in 2641 men and the risk of CVD-related death in 1950 men who had no history of CVD at baseline. During a mean follow-up time of 12.8 y, cardiovascular as well as noncardiovascular and all-cause mortality were lower among men with the highest consumption of fruits, berries and vegetables. After adjustment for the major CVD risk factors, the relative risk for men in the highest fifth of fruit, berry and vegetable intake for all-cause death, CVD-related and non-CVD-related death was 0.66 [95% confidence interval (CI) 0.50-0.88], 0.59 (0.33-1.06), and 0.68 (0.46-1.00), respectively, compared with men in the lowest fifth. These data show that a high fruit, berry and vegetable intake is associated with reduced risk of mortality in middle-aged Finnish men. Consequently, the findings of this work indicate that diets that are rich in plant-derived foods can promote longevity.

目的 了解湖南省浏阳市居民新鲜水果摄入频率情况,探讨新鲜水果摄入频率与脑卒中发病关联。 方法 利用中国慢性病前瞻性研究湖南省浏阳市项目点30～79岁常住居民基线调查数据和随访获得的脑卒中发病数据,利用Cox比例风险模型,在调整混杂因素后,评估新鲜水果摄入频率与脑卒中发病的关联。 结果 共57 288名研究对象纳入分析,浏阳市仅7.38%的研究对象每周有4 d及以上吃新鲜水果 。男性、家庭年收入水平低、文化程度低、吸烟、饮酒人群新鲜水果摄入频率较低(P<0.001)。2015—2019年共随访观察到2 720例脑卒中发病。增加新鲜水果摄入频率对脑卒中的发病有保护作用,与不吃或极少吃新鲜水果相比,每周有4 d及以上吃新鲜水果脑卒中的发病风险降低了28%(HR=0.72,95%CI:0.61~0.85),缺血性脑卒中的发病风险降低了25%(HR=0.75,95%CI:0.60~0.94),出血性脑卒中的发病风险降低了51%(HR=0.49,95%CI:0.35~0.76)。 结论 新鲜水果摄入频率增加能降低脑卒中发病风险。浏阳市居民新鲜水果摄入频率情况不容乐观,针对这一问题,需要采取适当措施以增加居民新鲜水果摄入频率。     

The relationships among socioeconomic status, fruit and vegetable intake, and alcohol consumption

Abstract Purpose . We examined the relationships among fruit and vegetable intake, alcohol consumption, and socioeconomic status (SES). We hypothesized that fruit and vegetable consumption would be inversely associated with alcohol consumption and the relationship would differ by SES. Design . A cross-sectional analysis. Setting . Large, urban Midwestern county. Subjects . A unique, racially/ethnically diverse sample of 9959 adults (response rate: 66.3%). Measures . Fruit and vegetable intake was measured using two items that assessed servings per day. Alcohol consumption was measured in terms of volume of alcohol consumed and binge drinking. Individual measures of SES included education and household income. Analysis . Weighted multivariate linear and Poisson regression were used to estimate effects. Results . The relationship between fruit and vegetable intake and alcohol consumption varied by SES. Those with lower household incomes who consumed five or more servings of fruits and vegetables per day were less likely to engage in binge drinking relative to those consuming zero to one servings of fruits and vegetables per day (risk ratio = .66; 95% confidence interval: .46, .95). No association was observed for higher-household-income individuals. Conclusion . We observed an inverse relationship between fruit and vegetable consumption and alcohol intake in those with lower household incomes but not in those with higher household incomes. Results suggest that the relationship between diet and alcohol consumption may be more relevant in populations with more restricted economic choices. Results are, however, based on cross-sectional data.     

Dietary intake and major food sources of polyphenols in Finnish adults

Phenolic acids, flavonoids, proanthocyanidins, and ellagitannins are polyphenols that may have beneficial effects on human health and provide protection against chronic diseases. To date, limited data exist on quantitative intake of polyphenols. The aims of this study were to estimate the quantitative intakes of polyphenols by using analyzed concentrations together with individual food consumption records and to determine major dietary sources. Analyzed concentrations of phenolic acids, anthocyanidins, and other flavonoids, proanthocyanidins, and ellagitannins (44 total polyphenol compounds) were entered into the national food composition database, Fineli. The absolute intakes of the polyphenols and the corresponding food sources were calculated on the basis of 48-h dietary recalls of 2007 Finnish adults. The mean total intake of polyphenols was 863 +/- 415 mg/d. Phenolic acids comprised the dominant group of polyphenols (75% of total intake) followed by proanthocyanidins (14%) and anthocyanidins and other flavonoids (10%). Due to their high consumption and high concentrations of phenolic acids, coffee and cereals were the main contributors to total polyphenol intake. Berries and berry products were the main source for anthocyanidins, ellagitannins, and proanthocyanidins, and fruits were the main source for flavonols, flavones, and flavanones. The results give additional support to the recommendations for a varied diet with fruits, berries, cereals, and vegetables.     

2013年中国25岁及以上人群水果摄入不足的归因死亡分析

目的 分析2013年我国≥ 25岁人群归因于水果摄入不足的死亡情况及其对期望寿命的影响。方法 利用2013年中国慢性病及其行为危险因素监测调查数据计算分性别和地区的水果摄入量,采用潜在影响分值（PIF）分析归因于水果摄入不足的相关疾病死亡数、死亡率及对期望寿命的影响情况。结果 2013年,我国≥ 25岁人群的水果摄入量平均为（113.3±168.9）g/d[男性为（103.6±160.1）g/d,女性为（122.7±176.6）g/d）],城市居民的水果摄入量明显高于农村地区,东部地区高于中部和西部地区;总死因中的15.21%是由于水果摄入不足造成的,水果摄入不足对相关疾病的PIF均约为35.00%。农村地区（16.50%）全死因的PIF高于城市地区（13.88%）,东部（15.48%）及中部（16.27%）全死因的PIF高于西部地区（13.75%）;归因于水果摄入不足导致死亡数约为134.84万,相关疾病死亡数依次为缺血性心脏病（47.25万）、出血性中风（33.88万）、缺血性中风（25.90万）、肺癌（20.84万）、食管癌（6.07万）、喉癌（0.54万）和口腔癌（0.36万）;城市的全死因及相关疾病的归因死亡数明显低于农村地区,中部地区的全死因归因死亡数（45.27万）高于东部（53.11万）及西部地区（36.46万）,我国因水果摄入不足造成期望寿命损失1.73岁（男性损失1.80岁,女性损失1.58岁）,农村高于城市,中部高于东部和西部地区。结论 我国水果摄入量与推荐标准相差甚远,水果摄入不足导致相关疾病的PIF较高,且对居民期望寿命的影响较为严重。     

Dietary fiber constituents of selected fruits and vegetables

This study compared the dietary fiber (DF), neutral detergent fiber (NDF), cellulose, hemicellulose, lignin, and pectin content of selected fruits and vegetables. Apples and peaches (fresh and canned), oranges (fresh), strawberries (fresh, canned, and frozen), carrots, green beans, and potatoes (fresh, fresh cooked, canned, and frozen), and tomatoes (fresh, fresh cooked, and canned) were studied. When possible, two varieties, two stores, and name and store brands were chosen. Samples were analyzed for NDF, acid detergent fiber, 72% sulfuric acid, lignin, and pectin. From those values, DF, cellulose, and hemicellulose were calculated. Fresh fruits in gm/100gm wet weight had decreasing DF, NDF, and hemicellulose values as follows: apples, peaches, strawberries, and oranges. Apples were highest in cellulose; strawberries, highest in lignin; and oranges, highest in pectin. Fresh-cooked vegetables in gm/100gm wet weight have decreasing DF and NDF values as follows: green beans, carrots, potatoes, and tomatoes. Green beans were highest in cellulose and hemicellulose; potatoes highest in lignin; and carrots highest in pectin. On a wet-weight basis, fresh apples and peaches, fresh-cooked green beans, canned carrots, and canned and frozen potatoes were higher in DF and NDF than other forms of the fruit or vegetable. There were few differences according to stores, brands, or varieties of fruits and vegetables. On a dry-weight basis, fresh apples, peaches, strawberries, green beans, and tomatoes appear to have higher DF and NDF contents than their processed counterparts. Fresh-cooked carrots and fresh potatoes appear to have less DF and NDF than their canned and frozen counterparts.     

5-A-DAY: dietary behavior and the fruit and vegetable intake of Latino children.

OBJECTIVES. The purpose of the study was to examine children's intake of fruits and vegetables in relation to the recent national "5-A-DAY" campaign. METHODS. Four 24-hour dietary recalls per child collected from 205 mothers of 4- to 5-year-old urban Latino children were used to analyze average 5-A-DAY fruit and vegetable consumption and examine associations between 5-A-DAY consumption, nutrient intakes, and eating patterns. RESULTS. The reported mean servings per day of fruits and vegetables, as defined by 5-A-DAY criteria, were 1.8 and 1.0, respectively, with only 6.8% (n = 14) of the children averaging five or more servings per day. Fruit juice accounted for 36% of 5-A-DAY servings. There were significant linear trends in intake of vitamins A and C, potassium, iron, cholesterol, protein, and fiber across quintiles of 5-A-DAY intake. There were no differences among quintiles in intake of saturated or total fat or in servings from most non-5-A-DAY food groups. CONCLUSIONS. Latino children's intake of fruits and vegetables falls far short of current recommendations. Fruit juice accounted for a disproportionate amount of 5-A-DAY intake in this population. Sensible 5-A-DAY interventions should take into consideration the existing eating patterns of the target population.     

Dietary Polyphenol Intake in US Adults and 10-Year Trends: 2007-2016

BackgroundPolyphenols are a class of phytochemicals that have antioxidant, anti-inflammatory, anticancer, and antiviral properties. Previous research suggests that dietary polyphenol intake is protective against major chronic diseases. To our knowledge, no data on polyphenol intake for the US adult population are available.ObjectiveThis study explored usual dietary polyphenol intake among US adults in 2013-2016 and examined trends in intake during 2007-2016 by demographic characteristics, and identified major dietary sources of polyphenols.DesignThe National Health and Nutrition Examination Survey is a series of cross-sectional surveys representative of the civilian noninstitutionalized US population.Participants/settingThis study included 9,773 adults aged 20 years and older.Main outcome measuresDietary and supplement data were obtained from two 24-hour dietary recalls. Polyphenol intake was estimated using the Phenol Explorer Database and adjusted for total energy intake.Statistical analysis performedUsual intake was estimated both overall and by demographic characteristics using the National Cancer Institute method. Trends in intake on a given day over 10 years were evaluated using regression analysis. The complex survey design was incorporated in all analyses.ResultsIn 2013-2016, the usual intake of dietary polyphenols was a mean (standard error) of 884.1 (20.4) mg per 1,000 kcal/d. Polyphenol intake was higher in adults 40 years and older, women, non-Hispanic White adults, and college graduates. During 2007-2016, the mean daily polyphenol intake did not change significantly over time for overall and demographic groups. Main polyphenol classes consumed were phenolic acids (mean [standard error] of 1,005.6 [34.3] mg/d) and flavonoids (mean [standard error] of 379.1 [10.7] mg/d). Foods and beverages contributed 99.8% of polyphenol intake, with coffee (39.6%), beans (9.8%), and tea (7.6%) as major dietary contributors.ConclusionFindings from this study suggest that polyphenol intake is consistent with the low intake of fruits, vegetables, and whole grains in the US population, and provide more evidence of the need for increased consumption of these food groups.     

Glycaemic index of fruits and fruit products in patients with diabetes

Patients with diabetes are often recommended to use whole fruit rather than canned fruit or fruit juice because of a belief that the addition of sucrose to canned fruit and the removal of dietary fibre to make fruit juice may increase blood glucose responses. However, the glycaemic responses of few fruits and fruit products have been assessed in patients with diabetes. Therefore, we determined the glycaemic index (GI) values of ten fruits and fruit products in patients with diabetes, for comparison with the GI of white bread (100). The mean ± s.e.m. GI values, with number of subjects in parentheses, were: pineapple juice, 66 ± 3 (13); grapefruit juice, 69 ± 5 (13); apple juice, 59 ± 8 (6); canned peaches, 74 ± 7 (11); canned pears, 63 ± 6 (10); canned apricots, 91 ± 6 (9); fruit cocktail, 79 ± 5 (8); dried apricots, 46 ± 7 (9); fresh oranges, 69 ± 11 (10); and fresh pears, 58 ± 7 (13). It is concluded that in patients with diabetes the glycaemic responses of various fruit products vary over a two-fold range. Most canned fruits and fruit juices tested had similar glycaemic responses to fresh fruits when equivalent amounts of carbohydrate were consumed.

目的 描述中国慢性病前瞻性研究(CKB)项目10个地区人群食物摄入频率特征的地区差异。方法 CKB项目于2004－2008年在城市和农村各5个地区募集自愿参加的30～79岁常住居民进入队列并完成基线调查。本研究分析10个项目地区中512 891名30～79岁队列成员12组食物的摄入频率,描述各食物组摄入频率特征的地区差异。结果 南方城市(99.0%)和南方农村(99.9%)人群每天摄入的谷类食物以大米为主,北方农村(99.0%)和北方城市如青岛(88.4%)人群则以面食为主。河南人群每天摄入杂粮人群比例最高(98.8%)。甘肃人群每天摄入新鲜蔬菜比例最低(74.0%)。在南方城市人群每天摄入新鲜水果、腌制蔬菜、肉类及其制品比例高于农村地区,北方也存在相同现象。北方城市(37.1%)和农村(14.6%)人群每天摄入蛋类及其制品高于南方城市(6.5%)和农村(6.9%)。北方城市地区人群每天摄入豆制品、乳类及其制品比例最高,其中哈尔滨人群每天摄入豆制品比例最高(10.0%),青岛人群每天摄入乳类及其制品比例最高(34.3%)。结论 CKB项目研究人群谷类食物、蛋类及其制品、豆制品摄入频率存在南北差异,肉类及其制品、家禽及其制品、水产/海产品、新鲜水果、腌制蔬菜、乳类及其制品摄入频率存在城乡差异。     

Marginal,Low, and Very-Low Food Security among Children Are Associated with Intake of Select Dietary Factors during Summer

BackgroundSchool meals are associated with improved food security status and dietary intake. Children receiving free and reduced-price school meals lose access to these meals during the summer. The association between food security status and dietary intake in these children during summer is unclear.ObjectiveTo examine the association between food security status (high, marginal, low, and very-low food security) among children and intake of select dietary factors during summer in children certified for free and reduced-price school meals by age group (3 to 4 years, 5 to 8 years, 9 to 12 years, and 13 to 17 years).DesignCross-sectional analysis.Participants/settingSecondary data from 11,873 children aged 3 to 17 years in the control group of the US Department of Agriculture Summer Electronic Benefit Transfer for Children Demonstration Project.Main outcome measuresConsumption of total fruits and vegetables; fruits and vegetables, excluding fried potatoes; whole grains; added sugars; added sugars, excluding cereals; added sugars from sugar-sweetened beverages; and dairy products assessed using questions from the 2009-2010 National Health and Nutrition Examination Survey Multifactor Diet Screener.Statistical analysisMultiple linear regression.ResultsFor the majority of age groups, marginal food security, low food security, and very-low food security were associated with lower fruit and vegetable consumption and low food security and very-low food security were associated with lower dairy consumption, with children from households with very-low food security having the lowest consumption. Children from households with very-low food security consumed 0.73 (95% CI –0.93 to –0.53) to 0.99 (95% CI –1.59 to –0.39) cup equivalents less per day of fruits and vegetables and 0.49 (95% CI –0.65 to –0.34) to 0.68 (95% CI –1.07 to –0.29) cup equivalents less per day of dairy compared with children from households experiencing high food security.ConclusionsLower food security was associated with reduced consumption of fruits and vegetables and dairy products during summer in children from low-income households.     

Most Americans eat much less than recommended amounts of fruits and vegetables

OBJECTIVE: To estimate the proportions of the population meeting recommendations for fruit and vegetable intake, we first estimated the usual intake distributions of total fruits and vegetables and then compared the results to the 5 A Day recommendation and to the recommendations for fruits and vegetables combined, found in the new US Department of Agriculture food guide, MyPyramid. DESIGN/SUBJECTS: The primary dataset was created from one 24-hour recall from each of 8,070 respondents in the 1999-2000 National Health and Nutrition Examination Survey. Variances were estimated using one or two 24-hour recalls from 14,963 respondents in the 1994-1996 Continuing Survey of Food Intakes by Individuals. STATISTICAL ANALYSIS: The statistical method developed at Iowa State University was used for estimating distributions of usual intake of dietary components that are consumed daily. It was modified to allow the adjustment of heterogeneous within-person variances using an external estimate of heterogeneity. RESULTS: In 1999-2000, only 40% of Americans ate an average of five or more (1/2)-cup servings of fruits and vegetables per day. The proportions of sex-age groups meeting the new US Department of Agriculture recommendations ranged from 0.7% of boys aged 14 to 18 years, whose combined recommendation is 5 cups, to 48% of children aged 2 to 3 years, whose combined recommendation is 2 cups. CONCLUSIONS: Americans need to consume more fruits and vegetables, especially dark green and orange vegetables and legumes. Nutritionists must help consumers realize that, for everyone older than age 3 years, the new recommendations for fruit and vegetable intakes are greater than the familiar five servings a day.     

Squeezing Fact from Fiction about 100% Fruit Juice

Total fruit intake in the United States is ~1 cup equivalent per day, or one-half of the 2010 Dietary Guidelines for Americans recommendation for adults. Two-thirds of the fruit consumed is whole fruit and one-third is 100% juice. The nutritional value of whole fruit, with the exception of fiber and vitamin C, may be retained with appropriate juice production methods and storage conditions. One-hundred percent fruit juice consumption is associated with a number of health benefits, such as improved cardiovascular health and decreased obesity, although some of these and other potential benefits are controversial. Comprehensive analyses of the evidence by the Academy of Nutrition and Dietetics in 2014, the US Dietary Guidelines Advisory Committee in 2010, and the Australian Dietary Guidelines of 2013 concluded that 100% fruit juice is not related to adiposity in children when consumed in appropriate amounts for age and energy needs. However, some reports suggest the consumption of fruit juice contributes to unhealthful outcomes, particularly among children. A dietary modeling study on the best ways to meet the fruit intake shortfall showed that a combination of whole fruit and 100% juice improved dietary density of potassium and vitamin C without significantly increasing total calories. Notably, 100% juice intake was capped at amounts consistent with the 2001 American Pediatric Association guidance. The preponderance of evidence supports the position that 100% fruit juice delivers essential nutrients and phytonutrients, provides year-round access to a variety of fruits, and is a cost-effective way to help people meet fruit recommendations.     

国家慢性病综合防控示范区居民蔬菜水果摄入情况及影响因素分析

目的 了解国家慢性病综合防控示范区（示范区）居民蔬菜水果摄入情况,探索影响示范区居民蔬菜和水果摄入的主要因素。方法 采用多阶段整群随机抽样的方法,于2016年11-12月对抽取的10个示范区4 000名≥ 18岁常住居民进行入户调查,使用问卷收集示范区居民人口社会学特征、健康相关行为养成等信息。结果 有效问卷为3 891份,72.1%的示范区居民每天摄入蔬菜;53.6%的居民每天摄入水果。知晓示范区活动的居民蔬菜和水果摄入充足的比例分别是不知晓者的3.017倍（95% CI：2.426~3.753）和1.261倍（95% CI：1.007~1.580）。参与示范区活动程度高的居民蔬菜摄入充足率（χ²=83.942,P<0.001）较高。居民参与示范区活动程度越高,水果摄入充足比例也越高（中：OR=1.431,95% CI：1.210~1.694;高：OR=1.573,95% CI：1.315~1.882）。结论 示范区创建提高了居民蔬菜和水果摄入充足率,在示范区开展的相关活动利于居民健康生活方式的养成。
