The Claim
In male Wistar rats, dietary intake of 10% sucrose or 10% high fructose corn syrup (HFCS-55) does not significantly alter fasting plasma insulin levels or HOMA-IR index compared to a whole grain control diet.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When male Wistar rats were fed diets containing 10% sucrose or 10% high fructose corn syrup, their fasting insulin levels and insulin resistance measures remained unchanged compared to rats fed a whole grain diet.
See the scientific wording
In male Wistar rats, consumption of diets with 10% sucrose or 10% high fructose corn syrup (HFCS-55) did not significantly alter fasting plasma insulin levels or HOMA-IR index compared to a whole grain control diet, indicating no measurable effect on insulin resistance under these experimental conditions.
The liver processes fructose and glucose from sugar without overloading insulin production, and muscles and fat cells continue to take up blood sugar normally, so insulin levels in the blood stay steady.
What the research says
1 studyRats that ate sugar or high fructose corn syrup had the same insulin levels and insulin resistance as rats eating plain grain — meaning neither sugar made their bodies worse at handling blood sugar under these conditions.
