The Claim
Higher consumption of ultra-processed foods is associated with lower sustainable lifestyle scores in diverse populations across Latin America and Spain, with the strongest associations found for fast food and sugary drinks.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat more ultra-processed foods, especially fast food and sugary drinks, tend to have lower scores for sustainable living habits.
See the scientific wording
Ultra-processed food consumption is inversely associated with sustainable lifestyle scores across diverse populations in Latin America and Spain, with the strongest associations observed for fast food and sugary drinks, suggesting that UPF intake may serve as a behavioral indicator of broader unsustainable consumption patterns.
Eating fast food and sugary drinks triggers strong pleasure signals in the brain, which reinforces repeated consumption and reduces interest in healthier, more sustainable choices like local or plant-based foods. This habit formation makes people more likely to drive instead of walk, buy packaged goods instead of bulk items, and ignore environmental impacts.
What the research says
1 studyStudy: Consumption of Ultra-Processed Foods and Sustainable Lifestyles: A Multicenter Study
People in Latin America and Spain who eat a lot of fast food and sugary drinks are much more likely to have lifestyles that harm the environment—like driving more and buying less local food. This study shows that eating these foods is a good sign someone has a less sustainable lifestyle overall.
