Preliminary Evidence of Diet Soda Harms

The study tracked the habits and health of 2,500 adults in Manhattan for nearly ten years. Those who drank diet soda had a 48% higher chance of either stroke or heart attack than those who didn’t drink soda at all. So far, the entire science between the finding hasn’t been concluded, but the study says the link exists regardless of factors like exercise, smoking, diabetes, weight and alcohol consumption. Even healthy people are victim to the diet soda.
Correlation, not intervention/control, but still: randomly selected (Manhattan) residents over a 10 year period. It’s suspicious to me that they didn’t mention caffeine, which is correlated with diet soda imbibed :)

Also, no study text available. Looks super-preliminary - press release science.

This was all I could find in the conference program:

Salt implicated in stroke risk by the same team:

It’s commonly recommended that people with high blood pressure avoid salt, so perhaps this is sensible. I refuse to modify my salt intake beyond what my taste tells me until I hear a better case that I specifically am at risk, or that on net the harms of a high-salt diet exceed the benefits.
