The Claim
Among Brazilian adolescents aged 12–17, consuming ultra-processed foods at or above 44.9% of daily caloric intake is associated with a 3.9% higher prevalence of low-grade inflammation, as indicated by C-reactive protein levels above 3 mg/L, after adjusting for age, sex, socioeconomic status, physical activity, and body composition.
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.
Brazilian adolescents aged 12–17 who get at least 44.9% of their daily calories from ultra-processed foods have a 3.9% higher rate of low-grade inflammation, measured by C-reactive protein levels above 3 mg/L, compared to those who consume less, after accounting for age, sex, socioeconomic status, physical activity, and body composition.
See the scientific wording
Among Brazilian adolescents aged 12–17, consuming ultra-processed foods at or above 44.9% of daily caloric intake is associated with a 3.9% higher prevalence of low-grade inflammation, as indicated by C-reactive protein levels above 3 mg/L, after adjusting for age, sex, socioeconomic status, physical activity, and body composition, though this association is not observed with specific types of ultra-processed foods.
Eating a lot of ultra-processed foods causes blood sugar to spike quickly, which stresses the body and damages blood vessels. This stress activates immune signals that tell the liver to make a protein called CRP. At the same time, these foods lack fiber and contain additives that harm gut bacteria, letting bacterial toxins leak into the bloodstream. These toxins further activate immune cells, which also signal the liver to produce more CRP.
What the research says
1 studyBrazilian teens who got more than 44.9% of their calories from packaged foods like chips and soda had a tiny bit more inflammation in their blood than those who ate less, but no single food like soda or candy was to blame—it was just eating a lot of these foods overall.
