A new analysis of food additive glutamate and cardiovascular risk in the large French NutriNet-Sante cohort was published in the American Journal of Clinical Nutrition on August 8, 2026, from the Touvier and Srour group, the team behind much of the influential additive and ultra processed food cohort work.
The digest logged this as a heads up item: this group's outputs reliably become consumer headlines within weeks. No direction or magnitude of association was extracted from the paper.
The numbers
| Cohort | NutriNet-Sante, France |
| Exposure and outcome | food additive glutamate and cardiovascular risk; effect sizes not extracted |
What this does not show
- Any effect size yet. The digest recorded the study's existence, journal, team and cohort; no direction or magnitude of association was extracted, so no finding is summarised here.
- Causation. NutriNet-Sante is an observational cohort with self reported diet. Additive exposure estimation and residual confounding limit causal reading of any association it reports.
- Athlete relevance. General nutrition epidemiology; nothing here is specific to exercise or endurance fueling.
Caveats worth holding
- Watch list item: the digest recorded existence and provenance only, with no findings extracted. Read the paper before citing any association.
- Observational cohort with self reported diet; associations from this design cannot establish causation.
- Same team behind much of the additive and ultra processed food cohort literature, so expect prominent secondary coverage that may outrun the evidence.
