The Claim
In adults with obesity, higher consumption of ultra-processed foods is associated with lower diet quality as measured by the Diet Quality Index–DQI-DFG, with individuals in the highest tertile (>35.4% of calories) having a lower mean diet quality score (37±10) compared to those in lower tertiles (45–47±9).
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.
Adults with obesity who eat more ultra-processed foods have lower diet quality scores on the Diet Quality Index–DQI-DFG than those who eat less of these foods.
See the scientific wording
In adults with obesity, higher consumption of ultra-processed foods is associated with lower diet quality, as measured by the Diet Quality Index–DQI-DFG, with individuals in the highest tertile (>35.4% of calories) classified as having a low-quality diet (score 37±10) compared to intermediate quality in lower tertiles (45–47±9).
Eating a lot of ultra-processed foods means eating less of fruits, vegetables, and whole proteins. This lowers the amount of fiber and essential nutrients entering the gut, which changes the types of bacteria living there and reduces the production of beneficial compounds that help regulate appetite and metabolism.
What the research says
1 studyPeople with obesity who ate more ultra-processed foods (like chips, sugary snacks, and processed meats) had much worse diets—eating fewer fruits, veggies, and proteins—than those who ate less of these foods.
