Looking at these, you'd be forgiven for thinking the consumption of stevia and/or splenda had been found to cause heart attacks.
The study wasn't even about these sweeteners - it was about erythritol. How much erythritol was consumed by the subjects of that study? They don't know - maybe none. The "link" between the substance and "major adverse cardiovascular events" was that people who had high levels of it in their blood were more likely to experience these events.
But the thing is, we produce erythritol in our bodies. And if we have certain chronic illnesses, we produce a lot more of it. Serum erythritol was already known to be a biomarker of metabolic disease. From that point of view this study found nothing new or interesting.
