ErythritolSweetener
Witkowski et al. 2023 (Nature Medicine, PMID 36849732) reported elevated plasma erythritol associated with major adverse cardiovascular events (MACE) in two cohorts (n=4,000+), with in-vitro and ex-vivo evidence of enhanced platelet aggregation. Replication is ongoing; FDA and EFSA have not changed their safety positions, but the signal is real and the additive is purely cosmetic. Better-established concern: GI tolerance — single doses above ~50 g cause osmotic diarrhea. Lower threshold for children.
