The Claim
The collapse of the food matrix in ultra-processed foods suppresses postprandial secretion of the satiety hormones GLP-1 and PYY by causing rapid nutrient absorption in the proximal intestine, which prevents nutrient delivery to the ileal L-cells that trigger these hormonal responses.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Ultra-processed foods break down quickly in the upper intestine, causing nutrients to be absorbed too fast and preventing them from reaching the lower intestine where signals for fullness are produced.
See the scientific wording
The collapse of the food matrix in ultra-processed foods suppresses postprandial secretion of the satiety hormones GLP-1 and PYY by causing rapid nutrient absorption in the proximal intestine, preventing nutrient delivery to the ileal L-cells that normally trigger these hormonal responses.
When food is heavily processed, its structure breaks down so completely that nutrients get absorbed too quickly in the upper gut, leaving no food particles to reach the lower gut where special cells detect fullness and release hormones that tell the brain to stop eating.
What the research says
1 studyWhen food is heavily processed, it breaks down too fast in your gut, so your body doesn’t get the signal that you’re full. This study shows people eat 500 extra calories a day on processed foods, even when they have the same nutrients, because the food’s structure is ruined and the fullness hormones don’t kick in.
