The Claim

Consumption of sucralose at 30% of the acceptable daily intake for 30 days in healthy lean individuals causes a 20.3% significant decrease in insulin sensitivity, as measured by the Matsuda index after a mixed meal tolerance test.

Source: Sucralose consumption modifies glucose homeostasis, gut microbiota, Curli protein, and related metabolites in healthy individuals: a randomized placebo-controlled, triple-blind trial.

Cause and effect

In plain English

In healthy lean individuals, consuming sucralose at 30% of the recommended daily limit for 30 days reduces insulin sensitivity by 20.3% during a mixed meal tolerance test.

See the scientific wording

Consumption of sucralose at 30% of the acceptable daily intake for 30 days in healthy lean individuals causes a 20.3% significant decrease in insulin sensitivity, as measured by the Matsuda index after a mixed meal tolerance test, suggesting a direct metabolic impact of this artificial sweetener on glucose regulation.

Why this might work

Sucralose changes the bacteria in the gut, causing more inflammatory bacterial proteins and higher levels of certain amino acids. These changes trigger low-grade inflammation and block insulin from working properly in muscle and fat tissue, so the body cannot remove sugar from the blood effectively after eating.

What the research says

1 study
  1. Study: Sucralose consumption modifies glucose homeostasis, gut microbiota, Curli protein, and related metabolites in healthy individuals: a randomized placebo-controlled, triple-blind trial.

    This study found that when healthy people took a common daily dose of sucralose for a month, their bodies became less able to use insulin properly, causing blood sugar to stay higher after meals. This matches exactly what the claim says.
