The Claim
Higher consumption of ultra-processed foods is associated with lower scores on the Nutrient Rich Food Index (NRF) and hybrid nutrient density in Iranian adults, indicating poorer overall diet quality.
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.
Iranian adults who eat more ultra-processed foods have lower nutrient density scores and poorer diet quality compared to those who eat less.
See the scientific wording
Higher consumption of ultra-processed foods is associated with lower scores on both the Nutrient Rich Food Index (NRF) and hybrid nutrient density, indicating poorer overall diet quality in Iranian adults.
When people eat more ultra-processed foods, they replace whole foods like fruits, vegetables, whole grains, and legumes. These whole foods naturally contain vitamins, minerals, and fiber. Without them, the body gets fewer essential nutrients and less fiber, which lowers overall diet quality.
What the research says
1 studyPeople in Iran who ate more ultra-processed foods had diets that were less nutritious — they got fewer healthy vitamins and minerals and ate less fruit, fiber, and whole grains. So yes, eating more junk food means your diet is worse overall.
