Abstract

Increased consumption of ultra-processed foods (UPF) is associated with higher incidences of many noncommunicable diseases (NCDs) and death from all causes. However, the association between UPF and cardiovascular disease (CVD) mortality remains controversial. Our study investigated whether UPF consumption is associated with a higher risk of death from all causes, NCDs, and CVD. This study includes 14,747 participants from the ELSA-Brasil cohort followed up over an eight-year period. The NOVA classification was used to estimate the proportion of UPF (grams/day) in one’s diet. Cox regression was also applied. After adjustment for sociodemographic, health, and behavioural factors, a 10% increase in UPF in participants’ diets raised the risk of death from all causes and NCDs by 10% (95%CI: 1.01-1.19) and 11% (95%CI:1.02-1.21), respectively. However, UPF consumption was not associated with CVD mortality. The findings support public policies aimed at reducing UPF consumption in an attempt to reduce the NCD burden.
