Americans swallow about 22 teaspoons of sugar each day.
The majority of the excess sugar comes from drinking soft drinks. Eating candy, cakes and cookies doesn't help either.
Now in a newly released scientific statement, the American Heart Association says it is time to cut way back.
"Take a good hard look at your diet," said Rachel K. Johnson, the statement's lead author and a professor of nutrition at the University of Vermont in Burlington. "Figure out where the sources of added sugars are and think about how to cut back on that."
Women should have no more than six teaspoons of sugar a day. It is the equivalent of about 100 calories.
And men should consume no more than nine teaspoons - or 150 calories.
However, the guidelines don't apply to naturally occurring sugars such as those found in fruit, vegetables and dairy products.
