Recent discoveries in inclusive food-based approaches and dietary patterns for reduction in risk for cardiovascular disease.

PURPOSE OF REVIEW: To discuss new evidence-based dietary recommendations founded on an inclusive food strategy and to address the challenges that are posed by integrating a growing list of heart healthy foods into the diet without increasing energy intake beyond that required to achieve a healthy body weight. RECENT FINDINGS: New food-based dietary recommendations issued by the American Heart Association with the objective of reducing risk for cardiovascular disease (CVD) promote an inclusionary approach. The American Heart Association recommends a variety of foods to target four major goals: achieve a healthy overall diet, achieve a healthy weight, promote desirable lipid levels, and promote desirable blood pressure. Specific foods recommended include fruits and vegetables, grain products (including whole grains), fish, lean meat and poultry, fat-free or low-fat dairy products, and legumes. In addition, the new National Cholesterol Education Program Adult Treatment Panel III recommends reductions in saturated fat and cholesterol and therapeutic dietary options for enhancing LDL-cholesterol lowering, with inclusion of plant stanols/sterols (2 g/day) and increased viscous (soluble) fiber (10-25 g/day). In parallel with the evolution of new dietary recommendations is the expanding list of specific foods that have cardioprotective effects. Additional foods on this list are nuts, soy, legumes, alcohol, tea, and garlic. SUMMARY: It will be challenging to include all foods that reduce CVD risk in the diet and still maintain energy control. Strategies are needed that facilitate developing heart healthy dietary patterns that maximally reduce CVD risk.

The relation of dietary patterns to future survival, health, and cardiovascular events in older adults.

BACKGROUND: There have been few long-term follow-up studies of older adults who follow different dietary patterns. METHODS: We cluster-analyzed data on dietary fat, fiber, protein, carbohydrate, and calorie consumption from the U.S. Cardiovascular Health Study (mean age=73), and examined the relationship of the dietary clusters to outcomes 10 years later. RESULTS: The five clusters were named "Healthy diet" (relatively high in fiber and carbohydrate and low in fat), "Unhealthy diet" (relatively high in protein and fat, relatively low in carbohydrates and fiber); "High Calorie," "Low Calorie," and "Low 4," which was distinguished by higher alcohol consumption. The clusters were strongly associated with demographic factors, health behaviors, and baseline health status. The Healthy diet cluster had the most years of life and years of healthy life, and the Unhealthy diet cluster had the fewest. The Low 4 cluster had the best cardiovascular outcomes. Differences were not usually large. CONCLUSIONS: Older adults who followed the healthy eating pattern had somewhat longer and healthier lives, and the cluster with more alcohol consumption was associated with fewer cardiovascular events. The unhealthy eating pattern had the worst outcomes.

Dietary patterns in a high-risk population for glucose intolerance. Japanese-Brazilian Diabetes Study Group.

We evaluated dietary habits as risk factor for glucose intolerance in a high risk population of Japanese-Brazilians enrolled in a study on the prevalence of diabetes (DM). Based on oral glucose tolerance test and WHO criteria, 331 had normal tolerance (NGT), 88 impaired tolerance (IGT) and 83 had type 2 DM (51 self-reported, 32 newly diagnosed diabetics). Clinical, laboratory and dietary data, assessed by food frequency questionnaire (FFQ), were compared between the NGT group and another composed of IGT and newly diagnosed DM (disturbed glucose tolerance or DGT group). Associations of total energy intake and nutrient intakes with glucose intolerance were analyzed by logistic regression. Also, subjects with NGT and DGT entered into separate models of multiple linear regression including BMI as the dependent variable, and total energy intake or each nutrient as independent variables. DGT group showed higher waist-to-hip ratio, blood pressure, plasma glucose and insulin levels and worse lipid profile. Total energy intake, macronutrients, fibers, alcohol and saturated fat intakes did not differ between groups; DGT was not associated with any nutrient intake in multivariate analyses. BMI of the subjects with DGT but not with NGT was associated with protein and cholesterol intakes in linear regression analysis. Our findings did not support an association between nutritional factors and glucose intolerance even in subjects who are unaware of their DGT, using FFQ to reflect current habits. However, we suggest that protein and cholesterol intakes may be markers of increased BMI. Despite assuming that obesity and insulin resistance precedes DM, FFQ may not be useful in the assessment of unfavorable dietary patterns among subjects at risk for glucose intolerance, such as Japanese-Brazilians with elevated BMI.

[Familial history of cancer and dietary pattern, serum cholesterol, serum protein and blood hemoglobin].

The relationships between the history of cancer in parents and the dietary pattern, serum cholesterol, serum protein and blood hemoglobin were examined to assess the possible role of lifestyle transmission in the familial aggregation of cancer. Individuals with history of cancer in parents were selected from a population of 1,221 individuals. Five age- and sex-matched controls for each case were selected from individuals, the parents of whom were alive at the age of the case parent. Intake of miso soup, pickles and milk product showed associations with the history of cancer in parents. It was also found that serum cholesterol was significantly lower in individuals with history of cancer other than stomach in the mother. Interestingly, serum protein, especially the globulin fraction, was found to be significantly lower among individuals with the history of cancer in parents. These findings suggest that lifestyle transmission might play some role in the familial aggregation of cancer.

Relationship of food intake and dietary patterns with blood pressure levels among middle-aged Japanese men.

To investigate the relationship of food intake habits and dietary patterns to blood pressure, a cross-sectional study was conducted for 473 middle-aged Japanese males. After adjustment for age, residence, occupation, body mass index and alcohol consumption, mean systolic and diastolic blood pressure (SBP and DBP) were inversely associated with each intake frequency of dairy products, coffee, fruits, egg, beef, pork and chicken. The adjusted mean SBP and DBP of the individuals with 'all (= three)' of the following three dietary habits; 'once and over/wk of dairy products', 'once and over/wk of fruits', and 'three times and over/wk of beef, pork or chicken', were 7.4 mmHg and 6.9 mmHg lower (p < 0.001, for each) than those of 'zero or one' group. According to the analyses on 3-days weighed food records of 157 volunteers, the adjusted mean daily intake of total protein, animal protein and potassium were markedly higher in the 'two' or the 'three' group than in the 'zero or one' group (p < 0.05, for each). These results suggest that habitual intake of dairy products, fruits, and meat or chicken may be associated with the reduction of blood pressure possibly through the intake of protein and potassium.

Nutritional status and dietary patterns in disabled people.

BACKGROUND AND AIM: Obesity, cardiovascular diseases, diabetes and osteoporosis are the most frequent pathologies among people with a severe reduction of physical activity. The impairment in nutritional status, consequent to quantitative and qualitative inadequacy of diet, could be one of the first steps in the development of co-morbidities in disabled subjects. In order to evaluate this hypothesis we investigated the nutritional status and the food intake in patients with physical or mental disabilities. METHODS AND RESULTS: Thirty-seven disabled subjects (24 with exclusively physical inactivity and 13 with mental retardation and physical inactivity) mean age 33.5+/-9.2 years and 25 healthy subjects (mean age 31.0+/-9.3 years) were enrolled. Anthropometric measurements, indirect calorimetry, dual-energy X-ray absorptiometry, dietary intake and biochemical parameters were collected for each subject. Forty percent of disabled were overweight and 14% were obese. Fat free mass (FFM) and bone mineral content (BMC) was lower and fat mass (FM) was higher than able-bodied control. Absolute resting energy expenditure (REE) was lower in disabled subjects, but this difference disappeared when REE was normalized to FFM. Dietary intake resulted unbalanced (16%, 31%, 50% of total daily energy intake derived from protein, lipid and carbohydrate respectively) with a distribution of dietary fatty acid quite far from the recommended ratio [3.1(SFA):4.1(MUFA):1.0(PUFA)] and an excessive consumption of simple carbohydrates (mean intake 17.5+/-4.9%). Insufficient intake of fibre, iron, calcium, potassium and zinc was also found. Finally, alterations in the cholesterol profile were evident in more than one third of the disabled subjects, whereas fasting glucose intolerance was evident in one fourth. CONCLUSION: This study shows a consistent nutritional status impairment in disabled patients resulting in an reduction of FFM and BMC, in an over-representation of FM and in a number of biochemical risk factors for cardiovascular disease. The altered nutritional status is counterparted by a widespread inadequacy of dietary patterns. This nutritional and dietary impairment occurs both in subjects with mental and physical diseases.

Adherence to the Mediterranean dietary pattern among the population of the Balearic Islands.

The aim of the present study was to assess the prevalence of the Mediterranean dietary pattern (MDP) in the population of the Balearic Islands and socio-demographic and lifestyle factors that might determine adherence to the MDP. A cross-sectional nutritional survey was carried out in the Balearic Islands between 1999 and 2000. A random sample (n 1200) of the adult population (16-65 years) was interviewed. Dietary questionnaires incorporating questions related to socio-economic status, education level, lifestyle factors and health status were utilised. Dietary habits were assessed by means of two 24 h recalls, and a quantitative food-frequency questionnaire. Adherence to the MDP was defined according to a score constructed considering the consumption of nine MDP characteristic components: high MUFA:saturated fatty acids ratio, moderate ethanol consumption, high legumes, cereals and roots, fruits, vegetables, and fish consumption, and low consumption of meat and milk. Then, socio-demographic, lifestyle and health status variables that could determine a higher or lower adherence were assessed. Adherence to the MDP among the population of the Balearic Islands was found to be 43.1 (sd 5.8)%, and was similar in all socio-demographic and lifestyle groups, with some differences according to age, sex and physical status. There was an increase in the percentage of adherence with age, which was greater in males than in females. A more physically active lifestyle was associated with a higher adherence to the MDP. The promotion of the Mediterranean lifestyle, including the MDP and greater physical activity, should be reinforced in the population of the Balearic Islands and especially in the younger generations.

Staging of dietary patterns among African American women.

This article describes the development of a behavioral staging algorithm for use in the Eat Well, Live Well Nutrition Program, a peer-delivered community-based program for African American women (N = 301). The authors examined whether increased frequency in performing low-fat eating behaviors and lower percentage calories from fat intake resulted as a participant moved through five stages of readiness to change each of five low-fat dietary patterns. Frequency of performing low-fat dietary behaviors was significantly different (p<.05) between four stages for the pattern of avoid fried foods, three stages for modify meats, and two stages for the patterns of substitution, avoid fat as seasoning, replacement. Percentage calories from fat were significantly different (p<.05) between four stages for the pattern of replacement, three stages for avoid fried foods and modify meats, and two stages for substitution and avoid fat as seasoning. Implications of these findings for the tailoring of community-based dietary programs are presented.

Effects of carbohydrate supplementation during intense training on dietary patterns, psychological status, and performance.

The purpose of this study was to determine the effects of carbohydrate supplementation during intense training on dietary patterns, psychological status, and markers of anaerobic and aerobic performance. Seven members of the U.S. National Field Hockey Team were matched to 7 team counterparts (N = 14). One group was blindly administered a carbohydrate drink containing 1 g.kg-1 of carbohydrate four times daily, while the remaining group blindly ingested a flavored placebo during 7 days of intense training. Subjects underwent pre- and posttraining aerobic and anaerobic assessments, recorded daily diet intake, and were administered the Profile of Mood States (POMS) psychological inventory prior to and following each practice. Results revealed that the carbohydrate-supplemented group had a greater (p < .05) total energy intake, carbohydrate intake, and change (pre vs. post) in time to maximal exhaustion following training while reporting less postpractice psychological fatigue. However, no significant differences were observed in remaining psychological, physiological, or performance-related variables.

Adolescent vegetarians: how well do their dietary patterns meet the healthy people 2010 objectives?

OBJECTIVES: To examine whether adolescent vegetarians were more likely than nonvegetarian peers to meet the dietary recommendations of the Healthy People 2010 objectives and to examine differences in other nutrients between these 2 groups. DESIGN: A total of 4746 adolescents from 31 middle and high schools in the Twin Cities area of Minnesota. Data were collected via self-report surveys, with a student response rate of 81.5%. SETTING: Urban secondary schools. PARTICIPANTS: Participants were equally divided by sex. The mean age was 14.9 years; 34.3% were in junior high school and 65.7% in high school. The racial/ethnic distribution was 48.5% white, 19.0% African American, 19.2% Asian American, 5.8% Hispanic, 3.5% American Indian, and 3.9% mixed or other. MAIN OUTCOME MEASURES: Questions on vegetarian status and whether particular foods (eggs, dairy foods, chicken, fish) were excluded. Dietary intake was assessed using the Youth and Adolescent Food Frequency Questionnaire. RESULTS: Vegetarian adolescents were significantly more likely than nonvegetarian adolescents to meet the Healthy People 2010 objectives. This was particularly noteworthy for total fat (70% vs 48%), saturated fat (65% vs 39%), daily servings of vegetables (26% vs 14%), and 5 or more servings of fruits and vegetables (39% vs 28%). Vegetarians were also less likely to eat fast food or drink regular soda and fruit drinks. Vegetarians consumed less vitamin B(12), more diet soda, more caffeine, and more iron. CONCLUSION: Adolescent vegetarians have a dietary pattern that is more likely than nonvegetarians to meet the Healthy People 2010 objectives.

Trends in the dietary patterns and prevalence of obesity among Greenlandic school children.

OBJECTIVE: The aim of the study was to examine the trends in the dietary patterns of selected food items and in the prevalence of self-perceived obesity in a population of Greenlandic schoolchildren. STUDY DESIGN: The study is based on three school surveys among Greenlandic schoolchildren, class 6 to 11 in public schools, and contributing to the Health Behaviour in School-aged Children (HBSC) Study. Data are collected through self-completed questionnaires administered in the classroom. Three surveys have been carried out in Greenland in 1994, 1998 and 2002 with the participation of 2,999, 3,057 and 2,010 pupils, respectively. RESULTS: The intake of vegetables has increased significantly since 1994, and the intake of fruits, sweets and soft drink has decreased significantly at a 5% level. An unchanged high proportion of schoolchildren report to be on a diet or consider themselves obese. CONCLUSION: Most of the observed trends are positive, with regard to intake of vegetables and sweets and consumption of soft drinks. The fact that a high proportion of schoolchildren consider themselves to be obese must be assumed to have a negative impact on the psychological well-being of this population. The results of the survey can reveal changes which have occurred over time for the specified population. This knowledge can be used in public health work and planning.

Effect of dietary patterns on ambulatory blood pressure : results from the Dietary Approaches to Stop Hypertension (DASH) Trial. DASH Collaborative Research Group.

We measured ambulatory blood pressure (ABP) in 354 participants in the Dietary Approaches to Stop Hypertension (DASH) Trial to determine the effect of dietary treatment on ABP (24-hour, day and night) and to assess participants' acceptance of and compliance with the ABP monitoring (ABPM) technique. After a 3-week run-in period on a control "typical" American diet, subjects (diastolic blood pressure [BP], 80 to 95 mm Hg; systolic BP, <160 mm Hg; mean age, 45 years) were randomly assigned to 1 of 3 diets for an 8-week intervention period: a continuation of the control diet; a diet rich in fruits and vegetables; and a "combination" diet that emphasized fruits, vegetables, and low-fat dairy products. We measured ABP at the end of the run-in and intervention periods. Both the fruit/vegetable and combination diets lowered 24-hour ABP significantly compared with the control diet (P<0. 0001 for systolic and diastolic pressures on both diets: control diet, -0.2/+0.1 mm Hg; fruit/vegetable diet, -3.2/-1.9 mm Hg; combination diet, -4.6/-2. 6 mm Hg). The combination diet lowered pressure during both day and night. Hypertensive subjects had a significantly greater response than normotensives to the combination diet (24-hour ABP, -10.1/-5.5 versus -2.3/-1.6 mm Hg, respectively). After correction for the control diet responses, the magnitude of BP lowering was not significantly different whether measured by ABPM or random-zero sphygmomanometry. Participant acceptance of ABPM was excellent: only 1 participant refused to wear the ABP monitor, and 7 subjects (2%) provided incomplete recordings. These results demonstrate that the DASH combination diet provides significant round-the-clock reduction in BP, especially in hypertensive participants.

Dietary patterns in 10 groups and the relationship with blood pressure. Collaborative Study Group for Cardiovascular Diseases and Their Risk Factors.

An epidemiological comparative study on dietary patterns and population means of blood pressure was undertaken in 10 groups (3 of workers, 6 of farmers, 1 of fishermen) of adult males and females of northeast, north, south, middle and east China. Standardized methods and record forms were used for blood pressure measurements and 24-hr dietary recall interviews. Simple correlation and linear regression, multiple regression (adjusted for age, sex and body mass index) and ridge regression were used to analyze the relationship of dietary electrolytes and animal protein to blood pressure. The results show a significant negative association of mean daily intake of Ca and animal protein with population mean blood pressure. Excluding the fishermen's group, mean daily intake of Na showed significant positive association with both systolic and diastolic blood pressure. The Chinese diet should probably be improved, increasing Ca and animal protein and cutting salt to a much lower level.

How different is the dietary pattern in non-alcoholic steatohepatitis patients?

BACKGROUND/AIMS: This study aimed at evaluating whether patients with non-alcoholic steatohepatitis (NASH) had a specific dietary pattern and how it compared with data representative from the same geographical region individuals. SUBJECTS AND METHODS: Clinical, biochemical and anthropometrics: weight, height, body mass index (BMI) and waist circumference were collected in 45 NASH patients. Diet history was assessed using a validated semi-quantitative food frequency questionnaire, analysed with the Food Processor Plus, and was compared, after adjustment for BMI, with data from a sample of 856 free-living individuals, frequency matched for sex and age. RESULTS: Patients' mean age was 49.6+/-10.6 years, 26 F: 19 M, BMI: 31.2+/-5.0 kg/m2. Comparison of their diet history with control data (C) revealed that carbohydrate consumption was lower in patients (P): P-243.6+/-5.7 g vs. C-261.5+/-1.6 g, P<0.05, and most patients had very low fibre intake. Conversely, total fat consumption was higher in patients: P-79.7+/-1.7 g vs. 73.0+/-0.4, P<0.01. A significantly higher intake of n-6 fatty acids (P=0.003) and n-6/n-3 ratio was found in patients, P<0.001. CONCLUSIONS: Our results suggest that the quality and combination of carbohydrates and fat intake may be more relevant than their isolated amount; an increased fat intake with an excessive amount of n-6 fatty acids can be implicated in promoting necro-inflammation, and provides further grounds for individualized dietary therapy.

Identification of dietary patterns using factor analysis in an epidemiological study in São Paulo.

CONTEXT AND OBJECTIVE: Diet and nutrition are environmental factors in health/disease relationships. From the epidemiological viewpoint, diet represents a complex set of highly correlated exposures. Our objective was to identify patterns of food intake in a group of individuals living in São Paulo, and to develop objective dietary measurements for epidemiological purposes. DESIGN AND LOCAL: Exploratory factor analysis of data in a case-control study in seven teaching hospitals in São Paulo. METHODS: The participants were 517 patients (260 oral cancer cases and 257 controls) admitted to the study hospitals between November 1998 and March 2001. The weekly intake frequencies for dairy products, cereals, meat, processed meat, vegetables, pulses, fruits and sweets were assessed by means of a semi-quantitative food frequency questionnaire. Dietary patterns were identified by factor analysis, based on the intake of the eight food groups, using principal component analysis as an extraction method followed by varimax rotation. RESULTS: Factor analysis identified three patterns that accounted for 55% of the total variability within the sample. The first pattern ("prudent") was characterized by vegetable, fruit and meat intake; the second ("traditional") by cereals (mainly rice) and pulses (mainly beans); and the third ("snacks") by dairy products and processed meat. CONCLUSION: This study identified food intake patterns through an a posteriori approach. Such analysis may be useful for nutritional intervention programs and, after computing scores for each individual according to the patterns identified, for establishing a relationship between diet and other epidemiological measurements of interest.

A clinical trial of the effects of dietary patterns on blood pressure. DASH Collaborative Research Group.

BACKGROUND: It is known that obesity, sodium intake, and alcohol consumption factors influence blood pressure. In this clinical trial, Dietary Approaches to Stop Hypertension, we assessed the effects of dietary patterns on blood pressure. METHODS: We enrolled 459 adults with systolic blood pressures of less than 160 mm Hg and diastolic blood pressures of 80 to 95 mm Hg. For three weeks, the subjects were fed a control diet that was low in fruits, vegetables, and dairy products, with a fat content typical of the average diet in the United States. They were then randomly assigned to receive for eight weeks the control diet, a diet rich in fruits and vegetables, or a "combination" diet rich in fruits, vegetables, and low-fat dairy products and with reduced saturated and total fat. Sodium intake and body weight were maintained at constant levels. RESULTS: At base line, the mean (+/-SD) systolic and diastolic blood pressures were 131.3+/-10.8 mm Hg and 84.7+/-4.7 mm Hg, respectively. The combination diet reduced systolic and diastolic blood pressure by 5.5 and 3.0 mm Hg more, respectively, than the control diet (P<0.001 for each); the fruits-and-vegetables diet reduced systolic blood pressure by 2.8 mm Hg more (P<0.001) and diastolic blood pressure by 1.1 mm Hg more than the control diet (P=0.07). Among the 133 subjects with hypertension (systolic pressure, > or =140 mm Hg; diastolic pressure, > or =90 mm Hg; or both), the combination diet reduced systolic and diastolic blood pressure by 11.4 and 5.5 mm Hg more, respectively, than the control diet (P<0.001 for each); among the 326 subjects without hypertension, the corresponding reductions were 3.5 mm Hg (P<0.001) and 2.1 mm Hg (P=0.003). CONCLUSIONS: A diet rich in fruits, vegetables, and low-fat dairy foods and with reduced saturated and total fat can substantially lower blood pressure. This diet offers an additional nutritional approach to preventing and treating hypertension.

A comprehensive outpatient weight reduction program: dietary patterns, psychological considerations, and treatment principles.

A comprehensive outpatient approach to weight reduction has the best chance of long-term success. This article outlines the dietitian's role and summarizes dietary patterns and psychological problems encountered in such a program at the University of Virginia Clinical Nutrition Center. Patients were assisted in making gradual changes in eating patterns through nutrition education and the use of behavior modification techniques. Initial food diaries often reflected a low intake of fruits, vegetables, whole grains, and legumes; increased consumption of these high-fiber foods is advocated as an aid to weight loss. Psychological support is an important component of the weight reduction process. The dietitian must be adequately prepared to provide this therapy but also must be able to recognize when patients should be referred for further psychological counseling. Two case studies are presented to illustrate the sabotage which must be dealt with by patients as they lose weight and struggle to maintain that weight loss.

Calcium intake in preschool children--a study of dietary patterns in a low socioeconomic community.

BACKGROUND: There is a lack of published data on sources and quantity of calcium intake in preschool children. STUDY OBJECTIVES: To assess calcium intake compared with the Dietary Reference Intake (DRI), to identify major food sources of calcium, and to compare dietary patterns of healthy preschool children who do and do not meet the calcium DRI. DESIGN: Cross-sectional study. SETTING: Primary care pediatrics practice at a large urban medical center. SUBJECTS: A group of 228 children aged 44 to 60 months in a low socioeconomic community. METHODS: Diet was assessed using three or four 24-hour recalls administered approximately three months apart to the parents. Nutrient values were computed using a dietary analysis program based on USDA values. RESULTS: Mean daily calcium intake was 852 mg/day (S.D., 271) and 44% reported mean calcium intake less than the DRI of 800 mg/day. Milk consumption accounted for 64.3% and cheese for 6.7% of the daily calcium intake. Multiple linear regression analysis adjusting for age, sex, race, body mass index, and total caloric intake confirmed the main contribution of mainly milk and, to a much lesser extent, cheese consumption, as determinants of calcium intake. All of the children who consumed less than 1.2 servings of milk (288 ml) milk per day reported mean daily calcium intake below the DRI. CONCLUSIONS: Calcium intake below the DRI may be common in preschool children in low socioeconomic communities, and is associated primarily with lower milk intake. These findings indicate the need to promote the consumption of low-fat milk in preschool children.
