"...linked to higher risk of strokes."
No. To link it to a higher risk of strokes, you would need to find more strokes than expected in people consuming it vs those who don't, after accounting for confounding factors.
What this study found was that human cerebral microvascular endothelial cells in culture change gene expression when exposed to the sweetener.
Prior studies suggest an epidemiological link to strokes, but the way this is reported is trash.
