A recent article in the Journal of the American Medical Association (JAMA. 2010;303(15):1490-1497) found a high intake of added sugar is associated with increased risk for low HDL cholesterol and high triglycerides (blood fats). The HDL cholesterol is the one that transports the cholesterol back to the liver where it is used. When the HDL is low it is associated with a higher level of heart attack and stroke risk.
Compared with adults who got less than 5% of their total energy intake from added sugars, those getting 17.5%–25% of their energy from added sugars were about twice as likely to have low HDL levels.
The message lower your sugar to lower you risk of heart attack and stroke.
