The Claim

Higher intake of ultra-processed foods during pregnancy is associated with elevated C-reactive protein levels, independent of total energy intake.

In plain English

Pregnant individuals who consume more ultra-processed foods have higher levels of C-reactive protein, a marker of inflammation in the blood, even when total calorie intake is accounted for.

See the scientific wording

Higher ultra-processed food intake during pregnancy is associated with elevated C-reactive protein levels, a marker of systemic inflammation, independent of total energy intake, suggesting a potential role for food processing beyond caloric content in driving maternal inflammation.

Why this might work

Ingredients in ultra-processed foods damage the lining of the gut, allowing bacteria and toxins to leak into the bloodstream, which activates immune cells to release inflammatory signals that raise C-reactive protein levels in the blood.

1 study
  1. Study: Associations of ultra-processed food intake with maternal weight change and cardiometabolic health and infant growth

    Pregnant women who ate more ultra-processed foods like chips and soda had higher levels of a blood marker for inflammation, even when they ate the same number of calories as others — meaning the food processing itself, not just calories, may be causing more inflammation.
