The Claim

Rapid nutrient absorption from ultra-processed foods triggers supraphysiological insulin spikes and hepatic de novo lipogenesis, which contribute to insulin resistance and non-alcoholic fatty liver disease through mitochondrial oxidative stress and endoplasmic reticulum dysfunction.

How it works
1 study reviewed
In plain English

Consuming ultra-processed foods causes abnormally high insulin levels and forces the liver to produce excess fat, leading to insulin resistance and fatty liver disease through cellular stress in mitochondria and the endoplasmic reticulum.

See the scientific wording

The rapid nutrient absorption from ultra-processed foods triggers supraphysiological insulin spikes and hepatic de novo lipogenesis, contributing to insulin resistance and non-alcoholic fatty liver disease through mitochondrial oxidative stress and endoplasmic reticulum dysfunction.

Why this might work

When food is heavily processed, it breaks down too quickly in the mouth and stomach, causing sugar and fat to flood into the bloodstream all at once. This forces the pancreas to release too much insulin, which tells the liver to turn excess sugar into fat. The liver gets overwhelmed, its energy factories (mitochondria) leak harmful molecules, and its internal packaging system (endoplasmic reticulum) gets stressed. These problems block insulin signals in the liver and muscles, making the body resistant to insulin, while fat builds up in the liver, causing disease.

  1. Study: The collapse of the food matrix: how ultra-processed foods impact satiety and metabolism by altering physical structure beyond nutrient composition

    When food is heavily processed, it gets digested too fast, making your body release too much insulin and turn extra sugar into fat in the liver. This study shows people eat 500 extra calories a day on processed foods—even when they have the same nutrients—because the food falls apart too quickly in the body.
