Typology of eaters based on conventional and organic food consumption: results from the NutriNet-Santé cohort study

AbstractLimited information is available on large-scale populations regarding the socio-demographic and nutrient profiles and eating behaviour of consumers, taking into account both organic and conventional foods. The aims of this study were to draw up a typology of consumers according to their eating habits, based both on their dietary patterns and the mode of food production, and to outline their socio-demographic, behavioural and nutritional characteristics. Data were collected from 28 245 participants of the NutriNet-Santé study. Dietary information was obtained using a 264-item, semi-quantitative, organic FFQ. To identify clusters of consumers, principal component analysis was applied on sixteen conventional and sixteen organic food groups followed by a clustering procedure. The following five clusters of consumers were identified: (1) a cluster characterised by low energy intake, low consumption of organic food and high prevalence of inadequate nutrient intakes; (2) a cluster of big eaters of conventional foods with high intakes of SFA and cholesterol; (3) a cluster with high consumption of organic food and relatively adequate nutritional diet quality; (4) a group with a high percentage of organic food consumers, 14 % of which were either vegetarians or vegans, who exhibited a high nutritional diet quality and a low prevalence of inadequate intakes of most vitamins except B12; and (5) a group of moderate organic food consumers with a particularly high intake of proteins and alcohol and a poor nutritional diet quality. These findings may have implications for future aetiological studies investigating the potential impact of organic food consumption.

Organic Food Consumption

AbstractPesticides are used in large quantities in current agriculture all over Europe. Some pesticides are suspected of having negative effects on human health. While the risk associated with occupational exposure is getting well-documented, evidence of dietary exposure to these molecules in the general population is lacking. The aim of this study is to describe dietary exposure to pesticides among NutriNet-Santé cohort participants’.NutriNet-Santé is a web-based cohort of French middle-aged adults launched in 2009. BioNutriNet is an ancillary study launched in 2014, aiming to measure organic and conventional food consumption and evaluate different dimensions of diet sustainability. Dietary intake of organic and conventional foods was assessed using a 264 items self-administered semi-quantitative food frequency questionnaire. Exposure to 25 commonly used pesticides was evaluated using contamination data from CVUA Stuttgart accounting for farming system. Dietary pesticide exposure profiles were identified using Non-Negative Matrix factorization (NMF), specially adapted for non-negative data with excess zeros. The NMF scores were then introduced in a hierarchical clustering process. Identified clusters were described in terms of sociodemographics, dietary patterns and exposure to pesticides.A total of 34,442 participants were selected. Four clusters were identified. All clusters seemed to be exposed to the same molecules, with gradual intensity. The first cluster was characterized by the lowest energy-intake, highest organic food consumption (26.9%) and lowest dietary pesticide exposure; participants had highest consumption levels of organic food groups, including fruits and vegetables. Proportion of male participants and of rural residents was higher than in other groups. Clusters 2 and 3 were characterized by intermediate energy intake, and low organic food consumption. High conventional fruits and vegetables intake and moderate pesticide exposure were observed in cluster 2, composed of a lower smokers’ proportion. Cluster 3 individuals were less exposed to pesticides than clusters 2 and 4, except for Spinosad and Pyrethrins. Cluster 4 was characterized by the highest energy intake, lowest organic food consumption (12.2%), and highest pesticide exposure ; high consumption levels of conventional fruits, vegetables and a higher proportion of vegetarians were observed. This cluster was composed of 85.6% female participants, mainly retired (47.5%), mostly living in cities of 200 000 inhabitants and more (48.2%), and physically active.Dietary pesticide exposures seem to vary across the clusters and depending on the proportion of organic food in the diet. High consumers of conventional fruits and vegetables consumers seem to be more exposed to our selection of pesticides.

Organic Food Consumption

Abstract Pesticides are commonly used in current agriculture and some negative effects are suspected for human health but evidence from dietary exposure in the general population is lacking. This study aimed to describe dietary pesticide exposure among French cohort participants. Organic and conventional food consumption was assessed using a self-administered semi-quantitative food frequency questionnaire in 2014 in the NutriNet-Santé cohort. Exposure to 25 commonly used pesticides was estimated using contamination data (CVUA Stuttgart) accounting for farming system. Dietary pesticide exposure profiles were identified using Non-negative Matrix Factorization, adapted for non-negative sparse data and then introduced in a hierarchical clustering process. The 6 identified clusters (n = 34,193) seemed to be exposed to the same molecules with gradual intensity. Cluster 1 was characterized by the lowest energy-intake and dietary pesticide exposure, and high consumption of organic food groups (23.3%). Proportion of male participants was higher than in other groups. Clusters 2 and 5 were characterized by intermediate energy intake, lower organic food consumption and intermediate pesticide exposure. High conventional fruits and vegetables intake and high pesticide exposure were observed in cluster 3, composed of a lower smokers’ proportion. Cluster 6 was characterized by the highest energy intake, lowest organic food consumption (9%), and highest pesticide exposure; high consumption levels of conventional fruits, vegetables and a higher proportion of vegans were observed. For cluster 4, pesticide exposure varied more across molecules than for other clusters. The highest exposures were observed for Acetamiprid, Azadirachtin, Cypermethrin, Pyrethrins, Spinosad pesticides. Proportion of organic food in the diet was the highest (31.5%). Dietary pesticide exposures seem to vary across the clusters and related to the proportion of organic food in the diet. Key messages Dietary pesticide exposures seemed to vary gradually across the clusters and depending on the proportion of organic food in the diet. High consumers of conventional FV in this cohort seem to be more exposed to our selection of pesticides.

Abstract Background UK adolescents consume fewer fruits and vegetables and more free sugars than any other age group. Established techniques to understand diet quality can be difficult to use with adolescents because of high participant burden. This study aimed to identify key foods that indicate variation in diet quality in UK adolescents for inclusion in a short food frequency questionnaire (FFQ) and to investigate the associations between adolescent diet quality, nutritional biomarkers and socio-demographic factors. Methods Dietary, demographic and biomarker data from waves 1–8 of the National Diet and Nutrition Survey rolling programme were used (n=2587; aged 11–18 years; 50% boys; n=≤997 biomarker data). Principal component analysis (PCA) was applied to 139 food groups to identify the key patterns within the data. Two diet quality scores, a 139-group and 20-group, were calculated using the PCA coefficients for each food group and multiplying by their standardised reported frequency of consumption and then summing across foods. The foods with the 10 strongest positive and 10 strongest negative coefficients from the PCA results were used for the 20-group score. Scores were standardised to have a zero mean and standard deviation of one. Results The first PCA component explained 3.0% of variance in the dietary data and described a dietary pattern broadly aligned with UK dietary recommendations. A correlation of 0.87 was observed between the 139-group and 20-group scores. Bland-Altman mean difference was 0.00 and 95% limits of agreement were − 0.98 to 0.98 SDs. Correlations, in the expected direction, were seen between each nutritional biomarker and both scores; results attenuated slightly for the 20-group score compared to the 139-group score. Better diet quality was observed among girls, non-white populations and in those from higher socio-economic backgrounds for both scores. Conclusions The diet quality score based on 20 food groups showed reasonable agreement with the 139-group score. Both scores were correlated with nutritional biomarkers. A short 20-item FFQ can provide a meaningful and easy-to-implement tool to assess diet quality in large scale observational and intervention studies with adolescents.

AbstractObjectiveWe aimed to assess dietary profiles of adults from the NutriNet-Santé cohort according to different levels of organic food consumption using detailed self-reported data on organic food intakes.DesignFood intakes were obtained using an organic food frequency questionnaire (Org-FFQ). The participants were ranked into five groups (quintiles, Q) according to the proportion of organic foods in their diet. To determine diet quality, two scores were computed reflecting adherence to food-based recommendations (mPNNS-GS) and the probability of adequate nutrient intake (PANDiet). Relationships between levels of organic food consumption and dietary characteristics were assessed using multivariable-adjusted ANCOVA models.SettingThe NutriNet-Santé Study.SubjectsFrench adults from the NutriNet-Santé Study (n 28 245).ResultsIntakes of foods of plant origin increased along with the contribution of organic foods to the diet while a reverse trend was identified for dairy products, cookies and soda (P-trend<0·0001). The diet quality scores increased from Q1 (mPNNS-GS, 7·89 (se 0·02); PANDiet: 63·04 (se 0·11)) to Q5 (mPNNS-GS, 8·78 (se 0·02); PANDiet, 69·37 (se 0·10)). Overall, high organic food consumers exhibited better diet quality, although intermediate organic food consumers showed better adherence to specific nutritional recommendations related to animal products.ConclusionsThe study provides new insights into the understanding of organic food consumption as a part of a healthy diet and sheds some light on the dietary profiles of different categories of organic food consumers. These results underline strong dietary behaviour correlates associated with organic food consumption that should be controlled for in future aetiological studies on organic foods and health.

Abstract Objectives Organic food consumption has been inversely associated with obesity in cross-sectional studies. Few have investigated this with prospective data. We examined whether organic food consumption was associated with the risk of obesity. Methods We used data from 37,706 eligible Sister Study (2003–2009) participants aged 35–74 years who provided information on frequency of organic food consumption. Participants reported their consumption of organic produce, meat, and dairy during the past 12 months as never, less than half the time, about half the time, or more than half the time. An organic diet score (ODS) was calculated by assigning scores of 0, 1, 2 and 3 for increasing consumption proportions and summing across food groups (maximum score 9). Prevalent obesity was based on measured general obesity (body mass index [BMI]≥30.0) and central obesity (waist circumference [WC] ≥88 cm, waist-to-height ratio [WHtR] ≥0.5). To evaluate incident overweight and obesity, self-reported BMI at enrollment was compared to self-reported BMI during follow-up (mean, 8.3 years). We used generalized log-linear models with robust error variance to estimate multivariable-adjusted prevalence ratios (PRs) and relative risks (RRs) for prevalent and incident obesity, respectively. Results At baseline, 62% of women reported eating organic food in the last 12 months. Compared with no consumption of organic food, higher ODS (≥3) was associated with a lower prevalence of obesity at baseline (PR for BMI = 0.98; 95% CI, 0.97–0.99; PR for WC = 0.94; 95% CI, 0.92–0.97; and PR for WtHR = 0.95; 95% CI, 0.93–0.98), after adjusting for socioeconomic, demographic, and lifestyle factors, including physical activity and other dietary measures. Higher ODS was inversely associated with gaining ≥5 kg (RR = 0.87; 95% CI, 0.82–0.92; P-trend < .001), a BMI increase ≥10% (RR = 0.88; 95% CI, 0.82–0.94; P-trend < .001). Among those who were not overweight or obese at enrollment, higher ODS was associated with becoming overweight (RR = 0.81; 95% CI, 0.73–0.91; P-trend < .001) or obese (RR, 0.84; 95% CI, 0.74–0.96; P-trend = .007). Associations did not differ by diet quality or socio-demographic factors. Conclusions Organic food consumption was associated with decreased risk of weight gain and decreased risk of becoming overweight or obese.

Organic Food Consumption

Organic food consumption has risen in many countries during the past decades, but individual motives leading to these choices remain unclear. This study aimed to evaluate the associations between cognitive restraint (CR), history of dieting and organic food intake. This cross-sectional analysis included 20,085 organic food consumers from the NutriNet-Santé cohort. CR (range score 1–4) was evaluated by the Three-Factor-Eating-Questionnaire and practice of dieting (never vs. past/current) was assessed by an ad hoc questionnaire. Frequencies of organic food intake overall and in 16 food groups were assessed by the Organic Food Frequency Questionnaire. Linear regression and analysis of covariance (ANCOVA) were performed to investigate the association between CR score, history of dieting and contribution of organic food intake to the total food intake. A lower overall contribution of organic options in the diet was observed in women with higher levels of CR (β = −3.61%, 95% CI: −4.32; −2.91 for 1 point of CR, p < 0.001) and with a history of dieting (31.1 ± 0.4% in past/current vs. 32.6 ± 0.3% in never dieters; p = 0.001). Consistent associations were observed in men with a history of dieting (26.4 ± 0.8% in past/current vs. 28.7 ± 0.4% in never dieters; p = 0.012). Overall, individuals—in particular women—with higher CR scores or with a history of dieting selected fewer organic food options. Our findings illustrate the complexity of potentially concurrent motives to food choices, in a context of increasing interest in organic food consumption.
