The Claim

In female Sprague-Dawley rats consuming a 13% (w/v) high-fructose corn syrup-55 solution for 8 weeks, hepatic triglyceride accumulation and total lipid content are significantly higher than in rats consuming sucrose or fructose solutions under conditions of equivalent caloric intake, indicating that the slightly higher fructose content in HFCS-55 promotes greater hepatic lipid deposition under hypercaloric conditions.

Source: High-fructose corn syrup-55 consumption alters hepatic lipid metabolism and promotes triglyceride accumulation.

How it works
1 study reviewed
In plain English

Female Sprague-Dawley rats fed a 13% high-fructose corn syrup-55 solution for 8 weeks developed higher levels of fat in the liver than rats fed equal calories of sucrose or fructose, due to the higher fructose content in the corn syrup.

See the scientific wording

In female Sprague-Dawley rats consuming a 13% (w/v) high-fructose corn syrup-55 solution for 8 weeks, hepatic triglyceride accumulation and total lipid content were significantly higher than in rats consuming sucrose or fructose solutions, despite equivalent caloric intake, indicating that the slightly higher fructose content in HFCS-55 promotes greater hepatic lipid deposition under hypercaloric conditions.

Why this might work

When HFCS-55 is consumed, the liver receives more fructose than from other sugars, which triggers the liver to make more fat from scratch, stops the liver from burning fat for energy, and blocks the liver from packaging and sending fat out of the body, causing fat to build up inside liver cells.

    Rats that drank a sugary solution with HFCS-55 got more fat in their livers than rats drinking the same amount of sugar from regular table sugar or pure fructose—even though they all ate the same calories. This suggests HFCS-55 is worse for the liver because of its specific mix of sugars.
