Several studies have found that consuming **artificially sweetened beverages — especially diet sodas with artificial sweeteners — is associated with a higher risk of both stroke and dementia, including Alzheimer’s disease, compared with people who rarely or never drink them. (American College of Cardiology)
🧠 What the Research Found
- In a long‑term population study, people who reported drinking artificially sweetened soft drinks daily had nearly three times the risk of ischemic stroke and Alzheimer’s dementia than those who did not consume these drinks. (PubMed)
- Importantly, in that same research, regular sugar‑sweetened sodas were not linked to increased stroke or dementia risk — the association was specific to artificially sweetened beverages. (PubMed)
🧠 What This Means
- These findings are associations, not proof of direct cause and effect — but they raise concern about frequent consumption of diet/artificially sweetened drinks and long‑term brain and vascular health. (NEJM Clinician)
- Many experts advise limiting intake of artificially sweetened soft drinks and choosing water, plain tea, or other minimally processed drinks instead.
In short:
👉 Diet or artificially sweetened soft drinks — such as many zero‑calorie sodas — have been linked in research to a higher risk of stroke and dementia when consumed frequently. (American College of Cardiology)
If you want, I can explain why artificial sweeteners might be linked to these risks and what healthier alternatives to choose.
