When researchers kept insulin levels high but blood sugar normal in rats for a week, the rats' bodies didn't hold onto more sodium than usual - their sodium levels stayed steady at about 0.34 mmol.

Seven Days of Euglycemic Hyperinsulinemia Induces Insulin Resistance for Glucose Metabolism but Not Hypertension, Elevated Catecholamine Levels, or Increased Sodium Retention in Conscious Normal Rats

Cohort Study

Animal

1997 Oct

The study gave rats insulin for 7 days while keeping their blood sugar normal, then measured how much sodium they retained. The results showed their sodium balance stayed exactly at 0.34 mmol the whole time - just like the claim says. The study confirms the claim is true.

Giving rats insulin for a week while keeping their blood sugar normal doesn't change their blood pressure.

Scientists found that when they kept rats with normal blood sugar on high insulin for a week, their stress hormone levels didn't change at all - they stayed exactly the same.

Scientists found that keeping insulin levels artificially high for a week made rats develop severe insulin resistance - their bodies became much worse at processing sugar, with glucose uptake dropping by 39% and sugar storage falling by 62%.
