The Claim
Genetically predicted artificial sweetener intake is associated with a 43.3% reduction in insulin sensitivity index, and this reduction mediates approximately 19.6% of the increased coronary heart disease risk associated with this genetic predisposition.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with genetic variants linked to higher artificial sweetener consumption have a 43.3% lower insulin sensitivity, and this reduced insulin sensitivity accounts for about 19.6% of their higher risk of coronary heart disease.
See the scientific wording
Genetically predicted artificial sweetener intake is associated with a 43.3% reduction in insulin sensitivity index, and this reduction mediates approximately 19.6% of the increased coronary heart disease risk linked to this genetic predisposition.
People with genetic traits that lead them to consume more artificial sweeteners experience a drop in how well their body responds to insulin. This causes blood sugar and insulin levels to stay high, which forces the liver to make more fat. The extra fat enters the bloodstream and builds up inside artery walls, making them stiff and inflamed. Over time, this narrows the heart's arteries and increases the chance of a heart attack.
What the research says
1 studyPeople who are genetically more likely to use artificial sweeteners also tend to have worse insulin sensitivity, and this worse insulin sensitivity explains about one-fifth of why they’re more likely to get heart disease. The study confirms this chain of events.
