Do Artificial Sweeteners Affect Your Brain? The Latest Evidence with Dr. Claudia Suemoto
In this episode of Causes or Cures, Dr. Eeks talks with Dr. Claudia Suemoto in Brazil about her new 8-year study looking at whether artificial sweeteners are linked to changes in thinking and memory.
We cover:
• How she started studying dementia and why she became curious about sweeteners.
• What the research team hoped to learn and what they actually found.
• Why these results are different from older, one-time “snapshot” studies.
• Why the link between sweeteners and thinking problems showed up in people under 60, but not over 60.
• The seven sweeteners they studied and whether any looked more concerning than others.
• What a small decline on a cognition test really means in everyday life.
• Whether people who switch to sweeteners because of health issues make sweeteners look guilty.
• Whether there seems to be a “safe range” or if more sweetener means more risk.
• How to use studies like this when they show association, not proof.
• Easy ways to cut back on sweeteners without doubling your sugar.
• What policies she thinks make sense while we wait for more data.
• Her top tips for protecting your brain and lowering dementia risk.
If you want a clear, calm, evidence-based take on sweeteners and brain health, this episode is for you.
