The Claim

The gastrointestinal transit effects of casein hydrolysis observed in rat pups do not apply to human preterm infants without additional clinical evidence.

Description
1 study reviewed
In plain English

Gastrointestinal responses to casein hydrolysis in rat pups cannot be used to predict how preterm human infants will respond without direct clinical studies in infants.

See the scientific wording

The gastrointestinal transit effects of casein hydrolysis observed in rat pups cannot be assumed to apply to human preterm infants without additional clinical evidence, as the study explicitly acknowledges its translational limitations.

Why this might work

When casein is broken down into small pieces before digestion, it stops releasing opioid-like substances that slow down the gut. Without these substances, the gut moves food through faster. This happens because the opioid substances normally block the muscles in the gut from contracting properly; when they are absent, the muscles contract more freely and push food along quicker.

  1. Study: Hydrolysis of Casein Accelerates Gastrointestinal Transit via Reduction of Opioid Receptor Agonists Released from Casein in Rats

    The study found that changing the type of protein made baby rats digest food faster, but the scientists themselves said we don't know if this happens in premature human babies — so we can't assume it does without testing it in humans.
