Here's a word of caution to those with a sweet tooth. reports that too much sugar may cause cardiovascular damage..

According to a study by researchers from the University of Texas Health Science Center at Houston (UTHealth), overconsumption of sugar may lead the heart to accumulate a small molecule called glucose 6-phosphate (G6P). This may then cause stress to the heart, affect muscle proteins, and eventually result in pump irregularities which then lead to heart failure.

The effect is especially dangerous for those who have existing cardiovascular issues. "When the heart muscle is already stressed from high blood pressure or other diseases, and then takes in too much glucose, it adds insult to injury," says principal investigator Heinrich Taegtmeyer.

In order to avoid the unhealthy accumulation of G6P, researchers recommend taking sugar in moderation, avoiding the excessive consumption of artificially sweetened food and drinks, and exercising regularly.
