The Claim

In male Wistar rats, consumption of high-fructose and high-fat diets reduces the expression of transcription factors PDX1, INSIG1, SREBP1c, FOXO1, and PEPCK, which regulate insulin production and hepatic glucose production, leading to impaired regulation of glucose metabolism in pancreatic beta cells and the liver.

Source: High-fructose diet is as detrimental as high-fat diet in the induction of insulin resistance and diabetes mediated by hepatic/pancreatic endoplasmic reticulum (ER) stress

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In male Wistar rats, diets high in fructose and fat reduce the activity of specific genes that control insulin production and liver glucose output, resulting in disrupted glucose metabolism in the pancreas and liver.

See the scientific wording

In male Wistar rats, high-fructose and high-fat diets reduce expression of key transcription factors regulating insulin production (PDX1, INSIG1, SREBP1c) and hepatic glucose production (FOXO1, PEPCK), suggesting impaired regulation of glucose metabolism in pancreatic beta cells and liver.

Why this might work

Eating too much sugar and fat overloads liver and pancreas cells with nutrients, causing stress in a cellular compartment called the endoplasmic reticulum. This stress triggers a chain reaction that shuts down genes needed to make insulin in the pancreas and to control sugar production in the liver. The stress also activates signals that kill insulin-producing cells and prevent the liver from responding to insulin, leading to high blood sugar.

  1. Study: High-fructose diet is as detrimental as high-fat diet in the induction of insulin resistance and diabetes mediated by hepatic/pancreatic endoplasmic reticulum (ER) stress

    In rats, eating too much sugar or fat lowers the activity of genes that help the pancreas make insulin and the liver control blood sugar, which can lead to diabetes-like problems.
