The Claim
Thirty days of sucralose consumption in healthy, non-habitual users is associated with reduced insulin sensitivity, concurrent alterations in gut microbiota composition, and elevated serum endotoxin levels.
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.
In healthy people who do not regularly consume artificial sweeteners, taking sucralose for 30 days is linked to decreased insulin sensitivity, changes in gut bacteria, and higher levels of endotoxin in the blood.
See the scientific wording
The reduction in insulin sensitivity induced by 30 days of sucralose consumption in healthy, non-habitual users is associated with concurrent changes in gut microbiota composition and elevated serum endotoxin, suggesting a potential microbiota-mediated mechanism for impaired glucose metabolism.
Sucralose changes the types of bacteria in the gut, causing more toxin-producing bacteria to grow. These bacteria release toxins that leak into the bloodstream. The toxins activate inflammation in the body, which blocks the ability of muscle, liver, and fat cells to respond to insulin, leading to higher blood sugar.
What the research says
1 studyThis study found that people who took sucralose for a month became less sensitive to insulin, and their gut bacteria changed in a way that let more bacterial toxins into their blood. This suggests the sugar substitute might be hurting metabolism through the gut bacteria.
