ABSTRACT

BACKGROUND/OBJECTIVES: Whole grain intake has been associated with a small but significant lower body weight gain in observational studies, but there is limited knowledge about the associations with specific whole grain types. The objective was to investigate the association between whole grains, different sources of whole grains and biomarkers of whole grain intake (alkylresorcinols) in relation to subsequent changes in waist circumference (WC) and body weight. SUBJECTS/METHODS: Cohort study of 57 053 participants with baseline information on whole grain intake from questionnaires (FFQ) and biomarkers of whole grain rye and wheat intake, plasma alkylresorcinols, for a subset. WC and body weight were measured at baseline and again at follow-up. The associations were estimated using multiple linear regression analyses and logistic regression. RESULTS: For women, overall whole grain intake was not related to changes in WC or body weight. For men, total whole grain intake was associated with gains in WC (ΔWC per 25 g increment: 0.44 cm, 95% CI: 0.34 cm; 0.54 cm) and body weight (Δweight per 25 g increment: 150 g, 95% CI: 78 g; 222 g), but the results changed to null or changed direction when adjusting for baseline anthropometry. For the different sources of whole grains, rye (women) and crispbread was significantly associated with gains in WC and body weight. Plasma alkylresorcinol concentration was associated with reduced WC, but not body weight, for women (ΔWC per 50 nmol/l increment: -0.69 cm, 95% CI:-1.26 cm;-0.13 cm), but no association was found for men. CONCLUSIONS: Overall, no strong relationship between whole grain intake, measured from questionnaires or using biomarkers was found in relation to changes in body weight and WC.

ABSTRACT

BACKGROUND/OBJECTIVES: Diets high in saturated and trans fat and low in unsaturated fat may increase type 2 diabetes (T2D) risk, but studies on foods high in fat per unit weight are sparse. We assessed whether the intake of vegetable oil, butter, margarine, nuts and seeds and cakes and cookies is related to incident T2D. SUBJECTS/METHODS: A case-cohort study was conducted, nested within eight countries of the European Prospective Investigation into Cancer (EPIC), with 12,403 incident T2D cases and a subcohort of 16,835 people, identified from a cohort of 340,234 people. Diet was assessed at baseline (1991-1999) by country-specific questionnaires. Country-specific hazard ratios (HRs) across four categories of fatty foods (nonconsumers and tertiles among consumers) were combined with random-effects meta-analysis. RESULTS: After adjustment not including body mass index (BMI), nonconsumers of butter, nuts and seeds and cakes and cookies were at higher T2D risk compared with the middle tertile of consumption. Among consumers, cakes and cookies were inversely related to T2D (HRs across increasing tertiles 1.14, 1.00 and 0.92, respectively; P-trend <0.0001). All these associations attenuated upon adjustment for BMI, except the higher risk of nonconsumers of cakes and cookies (HR 1.57). Higher consumption of margarine became positively associated after BMI adjustment (HRs across increasing consumption tertiles: 0.93, 1.00 and 1.12; P-trend 0.03). Within consumers, vegetable oil, butter and nuts and seeds were unrelated to T2D. CONCLUSIONS: Fatty foods were generally not associated with T2D, apart from weak positive association for margarine. The higher risk among nonconsumers of cakes and cookies needs further explanation.

ABSTRACT

BACKGROUND/OBJECTIVES: Follow-up studies have suggested that total intake of trans fatty acids (TFA) is a risk factor for gain in body weight and waist circumference (WC). However, in a cross-sectional study individual TFA isomers in adipose tissue had divergent associations with anthropometry. Our objective was to investigate the association between intake of TFA from ruminant dairy and meat products and subsequent changes in weight and WC. Furthermore, potential effect modification by sex, age, body mass index and WC at baseline was investigated. SUBJECTS/METHODS: Data on weight, WC, habitual diet and lifestyle were collected at baseline in a Danish cohort of 30,851 men and women aged 50-64 years. Follow-up information on weight and WC was collected 5 years after enrolment. The associations between intake of ruminant TFA (R-TFA) and changes in weight and WC were analysed using multiple linear regression with cubic spline modelling. RESULTS: Intake of R-TFA, both absolute and energy-adjusted intake, was significantly associated with weight change. Inverse associations were observed at lower intakes with a levelling-off at intakes >1.2 g/day and 0.4 energy percentage (E %). Absolute, but not energy-adjusted, intake of R-TFA was significantly associated with WC change. An inverse association was observed at lower intakes with a plateau above an intake of 1.2 g/day. CONCLUSIONS: The present study suggests that intake of R-TFA is weakly inversely associated with changes in weight, whereas no substantial association with changes in WC was found.

ABSTRACT

BACKGROUND/OBJECTIVES: The relation between lifetime use of alcohol and measures of abdominal and general adiposity is unknown. SUBJECTS/METHODS: Among 99,381 men and 158,796 women of the European Prospective Investigation into Cancer and Nutrition (EPIC) study, means of waist circumference (WC), waist-to-hip-ratio (WHR) and body mass index (BMI), and odds ratios (OR) for a larger WC than predicted for a given BMI (WClp=positive residuals of gender specific linear regression of BMI on WC) across categories of average lifetime use of alcohol (total, from wine and from beer) were calculated, all adjusted for socio-demographic, lifestyle and health factors. RESULTS: WC, WHR and BMI in men using lifetime ≤6 g/d alcohol were 95.1 cm, 0.942 and 27.3 kg/m(2), and 96.2 cm, 0.961 and 28.3 kg/m(2) when using >96 g/d. WC and WHR in women was 83.2 cm and 0.813 for ≤6 g/d, and 84.6 cm and 0.830 for >60 g/d, whereas BMI deviated only slightly with the lowest BMI (26.7 kg/m(2)) observed for >6-24 g/d. Compared with ≤6 g/d, OR for a WClp in both genders increased steadily across categories of alcohol use (up to 1.40 (95% confidence interval 1.32, 1.49) in men using >60 g/d and 1.63 (1.54, 1.73) in women using >24 g/d), though increase was higher for alcohol from beer than from wine (P for difference between beer and wine<0.001 (men) and=0.002 (women)). CONCLUSION: Lifetime alcohol use is positively related to abdominal and general adiposity in men, possibly following the male weight gain pattern; in women, it is positively related only to abdominal adiposity. In this context, beer may contribute additionally to abdominal adiposity.

ABSTRACT

BACKGROUND: As protein is considered to increase thermogenesis and satiety more than other macronutrients, it may have beneficial effects on prevention of weight gain and weight maintenance. OBJECTIVE: The objective of this study is to assess the association between the amount and type of dietary protein, and subsequent changes in weight and waist circumference (WC). METHODS: 89,432 men and women from five countries participating in European Prospective Investigation into Cancer and Nutrition (EPIC) were followed for a mean of 6.5 years. Associations between the intake of protein or subgroups of protein (from animal and plant sources) and changes in weight (g per year) or WC (cm per year) were investigated using gender and centre-specific multiple regression analyses. Adjustments were made for other baseline dietary factors, baseline anthropometrics, demographic and lifestyle factors and follow-up time. We used random effect meta-analyses to obtain pooled estimates across centres. RESULTS: Higher intake of total protein, and protein from animal sources was associated with subsequent weight gain for both genders, strongest among women, and the association was mainly attributable to protein from red and processed meat and poultry rather than from fish and dairy sources. There was no overall association between intake of plant protein and subsequent changes in weight. No clear overall associations between intakes of total protein or any of the subgroups and changes in WC were present. The associations showed some heterogeneity between centres, but pooling of estimates was still considered justified. CONCLUSION: A high intake of protein was not found associated with lower weight or waist gain in this observational study. In contrast, protein from food items of animal origin, especially meat and poultry, seemed to be positively associated with long-term weight gain. There were no clear associations for waist changes.

ABSTRACT

OBJECTIVE: The aim of this study was to examine the association of body mass index (BMI) and weight gain with eating at restaurants and similar establishments or eating at work among 10 European countries of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. SUBJECTS: This study included a representative sample of 24,310 randomly selected EPIC participants. METHODS: Single 24-h dietary recalls with information on the place of consumption were collected using standardized procedures between 1995 and 2000. Eating at restaurants was defined to include all eating and drinking occasions at restaurants, cafeterias, bars and fast food outlets. Eating at work included all eating and drinking occasions at the workplace. Associations between eating at restaurants or eating at work and BMI or annual weight changes were assessed using sex-specific linear mixed-effects models, controlling for potential confounders. RESULTS: In southern Europe energy intake at restaurants was higher than intake at work, whereas in northern Europe eating at work appeared to contribute more to the mean daily intake than eating at restaurants. Cross-sectionally, eating at restaurants was found to be positively associated with BMI only among men (ß=+0.24, P=0.003). Essentially no association was found between BMI and eating at work among both genders. In a prospective analysis among men, eating at restaurants was found to be positively, albeit nonsignificantly, associated with weight gain (ß=+0.05, P=0.368). No association was detected between energy intake at restaurants and weight changes, controlling for total energy intake. CONCLUSION: Among men, eating at restaurants and similar establishments was associated with higher BMI and possibly weight gain.

ABSTRACT

OBJECTIVES: To describe energy intake and its macronutrient and food sources among 27 regions in 10 countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. METHODS: Between 1995 and 2000, 36 034 subjects aged 35-74 years were administered a standardized 24-h dietary recall. Intakes of macronutrients (g/day) and energy (kcal/day) were estimated using standardized national nutrient databases. Mean intakes were weighted by season and day of the week and were adjusted for age, height and weight, after stratification by gender. Extreme low- and high-energy reporters were identified using Goldberg's cutoff points (ratio of energy intake and estimated basal metabolic rate <0.88 or >2.72), and their effects on macronutrient and energy intakes were studied. RESULTS: Low-energy reporting was more prevalent in women than in men. The exclusion of extreme-energy reporters substantially lowered the EPIC-wide range in mean energy intake from 2196-2877 to 2309-2866 kcal among men. For women, these ranges were 1659-2070 and 1873-2108 kcal. There was no north-south gradient in energy intake or in the prevalence of low-energy reporting. In most centres, cereals and cereal products were the largest contributors to energy intake. The food groups meat, dairy products and fats and oils were also important energy sources. In many centres, the highest mean energy intakes were observed on Saturdays. CONCLUSIONS: These data highlight and quantify the variations and similarities in energy intake and sources of energy intake among 10 European countries. The prevalence of low-energy reporting indicates that the study of energy intake is hampered by the problem of underreporting.

ABSTRACT

OBJECTIVES: This paper describes the dietary intake of total fat, saturated (SFA), monounsaturated (MUFA) and polyunsaturated fatty acids (PUFA) and cholesterol of participants in the European Prospective Investigation into Cancer and Nutrition (EPIC) in 27 centres across 10 countries. METHODS: Between 1995 and 2000, a stratified random sample of 36 034 participants (age range 35-74 years) completed a standardized 24-h dietary recall, assessed by means of the computer software EPIC-SOFT. Lipid intake data were calculated using a standardized nutrient database. RESULTS: On average, the contribution of fat to total energy intake was >or=34% of energy intake (%en) in women and >or=36%en in men for most EPIC centres, except for the British, Dutch and most Italian cohorts. Total fat (>40%en) and MUFA intakes (21%en, mainly from olive oil) were highest in Greece. Except for the Greek, Spanish and Italian centres, the average MUFA intake ranged between 10 and 13%en, with a high proportion derived from animal sources. SFA intake in women and men was lowest in the Greek, Spanish, Italian and UK cohorts with an average of

ABSTRACT

OBJECTIVES: To investigate whether dietary glycaemic index (GI) and glycaemic load (GL) were associated with subsequent weight and waist circumference change. DESIGN: Population-based prospective cohort study. SETTING: Five European countries, which are Denmark, Germany, Italy, The Netherlands and the United Kingdom. PARTICIPANTS: A total of 89,432 participants, aged 20-78 years (mean =53 years) at baseline and followed for 1.9-12.5 years (mean=6.5 years). All participants were free of self-reported cancer, cardiovascular diseases and diabetes at baseline. METHODS: Glycaemic index and GL were calculated on the basis of dietary intake assessed by food frequency questionnaires and by using a GI table developed for this study with published GI values as the main sources. Anthropometric data were collected both at baseline and at the end of follow-up. Multiple linear regression analyses were conducted in each centre and random-effect meta-analyses were used to combine the effects. Adjustment was made for baseline anthropometrics, demographic and lifestyle factors, follow-up duration and other dietary factors. RESULTS: Mean GI and GL were 57 and 134, respectively. Associations of GI and GL with subsequent changes of weight and waist circumference were heterogeneous across centres. Overall, with every 10-unit higher in GI, weight increased by 34 g per year (95% confidence interval (CI): -47, 115) and waist circumference increased by 0.19 cm per year (95% CI: 0.11, 0.27). With every 50-unit higher in GL, weight increased by 10 g per year (95% CI: -65, 85) and waist circumference increased by 0.06 cm per year (95% CI: -0.01, 0.13). CONCLUSIONS: Our findings do not support an effect of GI or GL on weight change. The positively significant association between GI, not GL, and subsequent gain in waist circumference may imply a beneficial role of lower GI diets in the prevention of abdominal obesity. However, further studies are needed to confirm this finding given the small effect observed in this study.

ABSTRACT

It has been hypothesized that visceral fat releases free fatty acids and adipokines and thereby exposes the liver to fat accumulation. The authors aimed to evaluate current epidemiologic evidence for an association between abdominal fat and liver fat content. Clinical and epidemiologic studies with data on abdominal fat and liver fat content were reviewed. Studies using waist circumference to estimate abdominal fat mass suggested a direct association between abdominal fat and liver fat content. Studies using imaging methods suggested a direct association between intraabdominal fat and liver fat content, but not between subcutaneous abdominal fat and liver fat content. In conclusion, clinical and epidemiologic studies of abdominal fat and liver fat content suggest a direct association between abdominal fat and liver fat content which is probably accounted for by visceral fat. However, results from the included studies do not allow strong conclusions regarding the temporal sequence of events. Future longitudinal studies are recommended to obtain additional information on associations and mechanisms. Both abdominal fat depots and other body compartments of interest should be included to further investigate the association between specific fat depots and liver fat content. Biomarkers may provide insight into underlying mechanisms.

ABSTRACT

OBJECTIVE: To estimate the intake of ruminant trans fatty acids (TFA) in the Danish population aged 1-80 years. DESIGN: Descriptive study. SUBJECTS: A sex- and age-stratified random sample drawn from the Danish Civil Registration System. A total of 3098 participants (51% female) aged 1-80 years were included. The participation was 66%. DIETARY INFORMATION: A 7-day dietary record. RESULTS: The estimated median intake of ruminant TFA was 1.4 g/day with the 80% central range being from 0.9 to 2.1 among children aged 1-6 years and 1.6 g/day (1.0-2.4) among children aged 7-14 years. The median TFA intake was 1.8 g/day (0.9-2.9) among adults aged 15-29 years and among adults aged 30-80 years. The intake expressed as percentage of energy intake was 0.8, 0.6, 0.7, and 0.7, respectively. Dairy products were the main source of ruminant TFA. CONCLUSIONS: The median intake of ruminant TFA in the Danish population aged 1-80 years is estimated to be 1.7 g/day (0.9-2.7), corresponding to 0.7% of energy intake (0.5-1.0), with dairy products being the main source of ruminant TFA. SPONSORSHIP: The Danish Heart Foundation (Grants 02-2-9-8-22010 and 03-2-9-4-22087) and the Female Researchers in Joint Action (FREJA) programme from the Danish Medical Research Council.

ABSTRACT

INTRODUCTION: The European Union is financing a large-scale campaign, in which olive oil is represented as the optimal fat for dietetic prevention of coronary heart disease. METHOD: We reviewed all controlled dietary studies comparing the effect on blood lipids of olive oil and alternative vegetable oils. Fifteen studies were identified. RESULTS: Consumption of olive oil was associated with significantly raised plasma concentrations of low density lipoprotein cholesterol (+6.5%), high density lipoprotein cholesterol (), and triglycerides (+7%) as compared with an average of the alternative oils. In the light of these differences in blood lipids and the risk coefficients published earlier, we calculated that the consumption of olive oil was associated with a 7% increase in the risk of coronary heart disease. CONCLUSION: We conclude that olive oil cannot be considered more cardioprotective than other unsaturated vegetable oils as judged from its effects on blood lipids.
