The Claim
High consumption of ultra-processed foods is associated with lower sustainable lifestyle scores after adjusting for age, sex, BMI, physical activity, smoking, and country of residence.
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 a lot of ultra-processed foods tend to have lower scores on measures of sustainable living, even when accounting for age, sex, body weight, exercise, smoking, and where they live.
See the scientific wording
High consumption of ultra-processed foods is associated with lower sustainable lifestyle scores independently of age, sex, BMI, physical activity, smoking, and country of residence, suggesting that UPF intake may be a distinct behavioral marker of unsustainable living patterns.
Eating lots of ultra-processed foods changes the bacteria in the gut, which triggers chronic low-grade inflammation throughout the body. This inflammation affects brain regions that control decision-making and self-control, making people less likely to choose environmentally friendly habits like walking instead of driving or avoiding single-use plastics.
What the research says
1 studyStudy: Consumption of Ultra-Processed Foods and Sustainable Lifestyles: A Multicenter Study
People who eat a lot of fast food, sugary drinks, and snacks are much more likely to have habits that harm the environment—like driving more or using too much plastic—even when you account for their age, weight, or where they live. This suggests that eating ultra-processed foods is a sign of a less sustainable lifestyle overall.
