Sugar: How much is too much?
To stay within healthy limits, start retraining your brain not to crave sweetened foods and beverages.
Sad to say, there isn't much room in a healthy diet for the sweet stuff. The American Heart Association (AHA) recommends that adult men take in no more than 150 calories per day of added sugar. That isn't that much—about the equivalent of nine teaspoons of table sugar, or a little more than the amount of sugar in a single 12-ounce can of regular Coke.
But 12 ounces of sweetened beverage appears to be enough to raise your risk of heart disease if you imbibe regularly. Researchers at the Harvard School of Public Health tracked about 43,000 men for 22 years. Men who drank the most sugar-sweetened beverages daily were 20% more likely to have a heart attack over the study period, compared with men who drank the fewest.
