Consumption of ultra‐processed foods and cognitive decline in the ELSA‐Brasil study: a prospective study

Consumption of ultra‐processed foods (UPF) has progressively increased worldwide in the last 30 years. High intake of UPF is associated with cardiovascular disease and cancer and hypothesized to induce systemic inflammation and oxidative stress. Although UPF may also be a risk factor for cognitive decline through these pathways, little is lnown about the effects of UPF on cognition. We aimed to investigate the longitudinal association between UPF consumption and cognitive decline in the ELSA‐Brasil study during 9 years of follow‐up.
