Reported organic food consumption and metabolic syndrome in older adults: cross-sectional and longitudinal analyses

Abstract Objective: The association between organic food consumption and biomarkers of inflammation, c-reactive protein (CRP) and cystatin C (CysC), were explored in this cross-sectional analysis of older adults. Design: Dietary data and organic food consumption was collected in 2013 from a Food Frequency Questionnaire (FFQ). Alternative Mediterranean diet score (A-MedDiet) was calculated as a measure of healthy eating. Biomarkers CRP and CysC were collected in serum or plasma in 2016. We used linear regression models to assess the associations between organic food consumption and CRP and CysC. Setting: This cross-sectional analysis uses data from the nationally representative, longitudinal panel study of Americans over 50, the Health and Retirement Study (HRS). Participants: The mean age of the analytic sample (n=3,815) was 64.3(SE 0.3) years with 54.4% being female. Results: Log CRP and log CysC were inversely associated with consuming organic food after adjusting for potential confounders (CRP: β= -0.096, 95% CI=(-0.159, -0.033)]; CysC: β=-0.033, 95% CI=(-0.051, -0.015)]. Log CRP maintained statistical significance [β=-0.080; 95% CI=(-0.144, -0.016)] after additional adjustments for the A-MedDiet, while log CysC lost statistically significant [β=-0.019; 95% CI=(-0.039, 0.000)]. The association between organic food consumption and log CRP was driven primarily by milk, fruit, vegetables, and cereals while log CysC was primarily driven by milk, eggs, and meat after adjustments for A-MedDiet. Conclusions: These findings support the hypothesis that organic food consumption is inversely associated with biomarkers of inflammation CRP and CysC, although residual confounding by healthy eating and socioeconomic status cannot be ruled out.

Organic Food Consumption

Abstract The increased prevalence and adverse health consequences of obesity have made it one of the leading public health issues in recent years. Importantly, several epidemiological studies have revealed significant associations between BMI and organic food consumption. However, although these studies have suggested that this factor holds promise to prevent obesity, they all suffer from methodological limitations, including self-reporting methods to assess BMI, not controlling for potential confounding factors or using a non-representative sample. Moreover, all were restricted to an adult sample. We present the results of a cross-sectional epidemiological study assessing the association of organic food consumption with BMI and obesity in a representative lifespan French sample (INCA3 study). Objective methods were used to measure BMI, and several potentially confounding variables were controlled for. In total, 1775 children and adolescents and 2121 adults underwent anthropometric measurements and completed questionnaires concerning their dietary habits and lifestyle. Unadjusted models systematically revealed negative associations between organic food consumption and both BMI and obesity across all age groups. These associations tended to remain statistically significant even after controlling for several confounding variables concerning socio-economic status, quality of the diet and physical activity. The effect sizes were, however, small. These data confirm the association between organic food consumption and obesity during both childhood and adulthood. Evidence from randomised controlled trials is required to investigate causality between organic food consumption and lower BMI or obesity rate.

Reported Data

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.

Organic Food Consumption

Abstract Objective: To study the association between organic food consumption and lifestyle, socio-demographics, and dietary habits. Design: Cohort participants completed detailed questionnaires about organic food consumption, diet, and lifestyle between 1999 and 2002. Polytomous logistic regression models were used to estimate the association between organic food consumption, and lifestyle, socio-demographics, and dietary habits. Setting: This cross-sectional study uses data from the Danish Diet, Cancer and Health cohort. Participants: A total of 43,209 men and women aged between 54 and 73 years were included in the study. Results: Overall, 15% reported never consuming organic food, 39% had low organic food consumption, 37% had medium organic food consumption and 10% had high organic food consumption. The relative risk of consuming organic food versus never consuming organic food was highest among women, persons with body mass index <25 kg/m2, persons with low alcohol intake, persons participating in sports, persons who did not smoke or were former smokers, and among persons who adhered to the Danish national dietary guidelines. Associations were more distinct with higher levels of organic food consumption. Conclusion: Based on a historical cohort of Danish adults, organic food consumption was associated with a generally healthy lifestyle, more favorable socio-demographics, and dietary habits. These findings have to be considered in the adjustment strategy for future studies linking organic food consumption with health outcomes.

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.
