Objective: We aimed to assess dietary profiles of adults from the NutriNet-Sante cohort according to different levels of organic food consumption using detailed self-reported data on organic food intakes. Design: Food 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. Setting: The NutriNet-Sante Study. Subjects: French adults from the NutriNet-Sante Study (n 28 245). Results: Intakes 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. Conclusions: The 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.
