The Claim
Higher dietary intake of artificial sweeteners is associated with increased incidence of cardiovascular disease, cerebrovascular disease, and coronary heart disease.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who consume more artificial sweeteners in their diet have a higher rate of cardiovascular disease, cerebrovascular disease, and coronary heart disease.
See the scientific wording
Higher dietary intake of artificial sweeteners is associated with increased incidence of cardiovascular disease, cerebrovascular disease, and coronary heart disease.
Artificial sweeteners change how the gut and pancreas respond to sugar, causing the body to release too much insulin and become less able to use it properly. This leads to high blood sugar and fat buildup in blood vessels, which damages the inner lining of arteries. At the same time, artificial sweeteners make blood platelets overly sticky, causing clots to form more easily. Together, these effects narrow arteries and trigger heart attacks and strokes.
What the research says
4 studiesPeople who eat or drink more artificial sweeteners were found to have a slightly higher chance of developing heart and blood vessel problems, even after accounting for other factors like genetics and diabetes. This suggests cutting back on artificial sweeteners might help protect your heart.
This big study found that people who eat or drink more artificial sweeteners, like those in diet sodas, were more likely to have heart problems, strokes, or heart disease over time compared to those who didn’t consume them.
This study found that people who are genetically more likely to consume artificial sweeteners also have a higher risk of heart disease, suggesting the sweeteners might be causing the problem — not the other way around.
This study found that people who naturally have higher levels of erythritol (a sugar substitute) in their bodies are more likely to have heart attacks and strokes, suggesting that consuming more of this sweetener might increase heart disease risk.
