Association Between Ultraprocessed Food Consumption and Risk of Mortality Among Middle-aged Adults in France.

Overview

Schnabel L et al.. JAMA Intern Med 2019 · PMID 30742202 · DOI 10.1001/jamainternmed.2018.7289

Each 10% more ultra-processed food was linked with 14% higher death risk.

Does the study support the specific claim? Yes · Methodological quality: moderate

Study explained simply

What did the researchers want to find out?: Is UPF consumption associated with all-cause mortality?
How was the study done?: Prospective cohort (NutriNet-Santé), web 24-h records.
How many people, animals or samples were studied?: 44,551; 602 deaths; Adults >=45 y, 73% women
What was actually found?: HR per 10% increment 1.14 (1.04-1.27); UPF 14.4% of weight, 29.1% of energy; higher UPF linked to lower income/education, living alone, higher BMI, lower activity.
How large was the observed effect?: HR 1.14 per 10%
What do the results mean in everyday life?: Association only.
What are the study's limitations?: Volunteer cohort, mostly women; Few deaths; NOVA misclassification possible; Residual confounding; Self-reported diet
What does it say about Elawady's specific claim?: Supports C-UPF-03.
Do the results apply to Germany and Europe?: High (France).
What can explicitly not be concluded from this study?: Causation.

Is UPF consumption associated with all-cause mortality?

Study design: Cohort study – Prospective cohort (NutriNet-Santé), web 24-h records.
Population: Adults >=45 y, 73% women
Country: France
Period: 2009-2017; median 7.1 y
Sample size: 44,551; 602 deaths
Inclusion and exclusion criteria: >=1 set of 3 records in first 2 years

Results: HR per 10% increment 1.14 (1.04-1.27); UPF 14.4% of weight, 29.1% of energy; higher UPF linked to lower income/education, living alone, higher BMI, lower activity.
Absolute risks: 602 deaths (1.4%)
Authors' conclusion: UPF consumption appears associated with higher mortality; further studies needed.

Modest HR.

Supports C-UPF-03.

None.

High (France).

Supportive cohort.
