The Claim
Each additional teaspoon of artificial sweetener consumed daily is associated with a 1.2% increased risk of incident cardiovascular disease, a 1.8% increased risk of coronary artery disease, and a 3.5% increased risk of peripheral arterial disease in middle-aged and older adults, independent of lifestyle, metabolic, and genetic factors.
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.
In middle-aged and older adults, consuming one more teaspoon of artificial sweetener per day is linked to higher rates of cardiovascular disease, coronary artery disease, and peripheral arterial disease.
See the scientific wording
Each additional teaspoon of artificial sweetener consumed daily is associated with a 1.2% increased risk of incident cardiovascular disease, a 1.8% increased risk of coronary artery disease, and a 3.5% increased risk of peripheral arterial disease in middle-aged and older adults, independent of lifestyle, metabolic, and genetic factors, suggesting a consistent link between low-calorie sweetener intake and vascular health risks.
When people consume artificial sweeteners, the chemicals change the bacteria in the gut, which causes the body to release more insulin even when there is no sugar to process. Over time, this makes the body less able to control blood sugar, leading to high blood sugar levels that damage the lining of blood vessels. This damage causes inflammation and thickening of artery walls, which blocks blood flow and leads to heart attacks, strokes, and poor circulation in the legs.
What the research says
1 studyThis study found that people who add one more teaspoon of artificial sweetener each day have a tiny but real increase in their risk of heart and artery problems over time, even if they’re healthy, fit, or don’t have a family history of heart disease. The sweetener might be causing harm by increasing diabetes risk, which then leads to heart issues.
