Health impacts of artificial sweeteners

Entities: University of Colorado Boulder · duloxetine · Maple syrup · UK Biobank · Neurology (journal)

Overview

A systematic review of 21 randomized trials (July 2026) found that saccharin, aspartame, sucralose and stevia raise fasting insulin, HbA1c and may impair insulin sensitivity versus non‑caloric controls. Laboratory work at the University of Cambridge showed that roughly a quarter of tested sweeteners suppress the growth of at least one beneficial gut bacterium, and that common additives and several antidepressants generate more than 100 unexpected interactions that further disrupt the microbiome. A follow‑up Cambridge study of 39 widely used sweeteners on 25 gut‑bacterial species reported that about three‑quarters altered the growth of at least one strain; the stevia‑derived sweetener isosteviol, when combined with duloxetine, markedly reduced microbial diversity in an artificial gut model. Observational data from a Brazilian cohort of nearly 13,000 adults followed for eight years linked six artificial sweeteners (all except tagatose) to a 62 % faster overall cognitive decline—equivalent to roughly 1.6 years of additional brain aging—especially among participants under 60 and those with diabetes, with the highest‑risk intake level around 191 mg per day (one diet‑soda can). Neurology journals (July 2026) added that frequent consumption of aspartame, sucralose and acesulfame potassium is associated with accelerated cerebral aging and memory impairment, though lifestyle confounders remain a concern. Nutrition commentary highlighted Canadian maple syrup and dried plums as lower‑glycemic, nutrient‑rich alternatives. New Neurology data (August 2026) reaffirmed a 62 % faster rate of cognitive decline for daily users of low‑calorie sweeteners, identifying erythritol among six problematic compounds. Laboratory experiments from the University of Colorado Boulder suggested erythritol may impair the blood‑brain barrier by reducing nitric‑oxide production, raising endothelin‑1, lowering plasminogen activators and increasing free‑radical formation, mechanisms that could elevate stroke risk. Both studies are observational; causality has not been established.

Claims

What the coverage asserts, and how well corroborated each claim is across sources.

[● 7 SOURCES] Erythritol impairs the function of the blood‑brain barrier. (laboratory study)
[● 7 SOURCES] The studies are observational; a direct causal link has not been established. (caveat)
[● 6 SOURCES] Erythritol reduces nitric oxide production and increases endothelin‑1 levels in endothelial cells. (laboratory study)
[● 6 SOURCES] Erythritol lowers plasminogen activator release and raises free‑radical formation, potentially promoting vascular constriction and clot formation. (laboratory study)
[○ 1 SOURCE] Daily consumption of low‑calorie sweeteners is associated with a 62 % faster cognitive decline. (observational)
[○ 1 SOURCE] An average intake of 191 mg of sweeteners per day corresponds to about 1.6 years of additional brain aging. (observational)
[○ 1 SOURCE] Six of seven studied sweeteners (aspartame, saccharin, erythritol, etc.) were deemed problematic; tagatose was not. (observational)
[○ 1 SOURCE] People under 60 and diabetics showed a stronger association between sweetener intake and cognitive decline. (observational)
