Key points from article :
Xylitol, a sugar alcohol sweetener in sugar-free products, is linked to higher risk of heart attack and stroke.
It is found naturally in fruits and vegetables but at much lower levels than commercially added amounts.
Researchers studied over 3,000 people for three years and found those with high blood xylitol had a higher risk of cardiovascular events.
Lab tests showed xylitol increases blood cell clotting which can block blood flow and raise heart attack/stroke risk.
The mice also had significantly faster clot formation in their veins after receiving xylitol injections.
Experts advise consumers to be aware of potential risks but not to avoid products with low xylitol content.
More research is needed on the impact of all artificial sweeteners on cardiovascular health.
