The Claim

Consumption of sucralose for 30 days in healthy lean individuals increases the postprandial areas under the curve for glucose, insulin, and GLP-1, indicating altered hormonal responses to meals.

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
1 study reviewed
In plain English

In healthy lean people, drinking sucralose for 30 days leads to higher levels of glucose, insulin, and GLP-1 in the blood after meals compared to baseline.

See the scientific wording

Sucralose consumption for 30 days in healthy lean individuals increases postprandial glucose, insulin, and GLP-1 areas under the curve, indicating altered hormonal responses to meals.

Why this might work

After consuming sucralose for 30 days, bacteria in the gut change in a way that produces more inflammatory proteins and raises levels of certain amino acids. These changes cause muscle and fat tissue to become less responsive to insulin, so sugar stays in the blood longer after eating. The pancreas releases more insulin to compensate, and the gut releases more GLP-1 to try to lower blood sugar, resulting in higher overall levels of all three after meals.

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

    After people took sucralose for a month, their blood sugar, insulin, and a gut hormone called GLP-1 spiked higher after meals than before, meaning their bodies reacted differently to food. This suggests sucralose might mess with how the body handles sugar.
