Are dietary changes over eight years in the prospective NutriNet-Santé cohort consistent with the EAT-Lancet reference diet?

Background: The transition toward sustainable dietary patterns, such as the planetary diet proposed by the EAT-Lancet Commission, is warranted to optimize health and achieve environmental sustainability.

Objectives: To examine the extent to which the evolution of dietary changes over an 8-y period in the French NutriNet-Santé cohort aligned with the EAT-Lancet diet.

Methods: A sample of 17,187 participants of the prospective NutriNet-Santé study was used.

Dietary pattern trajectories in French adults of the NutriNet-Santé cohort over time (2014-2022): role of socio-economic factors.

Despite the urgent need for plant-based dietary shifts, few studies have examined current diet trajectories using longitudinal data. This study analyzed dietary transitions of French adults over 8 years (2014-2022), assessing diet quality and the role of various socio-economic factors. Consumption data from 17 187 NutriNet-Santé cohort participants, weighted for the French Census, were collected via FFQ in 2014, 2018 and 2022.

The nature of protein intake as a discriminating factor of diet sustainability: a multi-criteria approach.

Animal production is responsible for 56-58% of the GHG emissions and limiting meat consumption would strongly contribute to reducing human health risks in Western countries. This study aimed to investigate the nature of protein intake as a discriminating factor for diets' sustainability. Using data from 29,210 French adults involved in the NutriNet-Santé cohort, we identified clusters according to 23 protein sources.
