Does Diet Soda Cause Alzheimer’s? The Truth Revealed
Some studies suggest a potential link between diet soda consumption and increased Alzheimer’s risk, but more research is needed for definitive conclusions.
Many people switch to diet soda to cut calories, but recent studies suggest a possible link to Alzheimer’s disease. While research is ongoing, the evidence isn’t conclusive. Here’s what you need to know.
The Study Linking Diet Soda to Dementia
A 2017 study from Boston University School of Medicine followed over 4,000 people for ten years. It found that those who drank one or more artificially sweetened beverages daily had a higher risk of stroke and dementia compared to those who rarely consumed them.
However, this study only showed correlation—not causation. Other factors, like diabetes or obesity, could also play a role. For example, people with diabetes often choose diet soda to manage sugar intake, and diabetes itself increases dementia risk.
Why Might Artificial Sweeteners Affect the Brain?
Researchers have two main theories:
- Artificial sweeteners trick the brain. They may make people crave more sugar, leading to poor dietary habits linked to dementia.
- They may harm gut bacteria. Some artificial sweeteners break down into metabolites that could impact brain function.
Does Sugar Also Increase Dementia Risk?
Yes. High sugar intake is tied to diabetes, which disrupts brain function by affecting glucose levels. Excess sugar can also lead to beta-amyloid plaques, a hallmark of Alzheimer’s.
Balanced blood sugar is key. Too much or too little glucose can harm the hippocampus, the brain’s memory center.
What About Other Risk Factors?
Diet soda alone isn’t the sole culprit. Other factors include:
| Risk Factor | Impact on Dementia |
|---|---|
| High Blood Pressure | Increases stroke and vascular dementia risk |
| Lack of Mental Stimulation | Speeds cognitive decline |
| Poor Diet | Contributes to inflammation and brain damage |
Should You Stop Drinking Diet Soda?
While more research is needed, moderation is wise. Instead of diet soda, consider healthier options like:
- Water infused with lemon or berries
- Herbal teas
- Sparkling water with natural flavors
If you enjoy smoothies, try using a high-quality blender to make nutrient-rich drinks. For a refreshing alternative, check out our guide on the best ice cream for milkshakes.
What Experts Recommend
To lower dementia risk, focus on overall health:
- Exercise regularly to improve blood flow to the brain.
- Eat a balanced diet rich in antioxidants.
- Stay mentally active with puzzles, reading, or learning new skills.

Final Thoughts
The link between diet soda and Alzheimer’s isn’t proven, but reducing artificial sweeteners may benefit long-term health. Opt for natural beverages and maintain a healthy lifestyle to protect your brain.
