Coffee isn't the only place sugar sneaks in. Having a can of cola every day adds nine teaspoons of sugar to your diet.
Fruit drinks are no bargain either.
A 12-ounce glass of a fruit drink adds 12 teaspoons of sugar to your daily total. If you switch to 100 percent juice, such as orange or grapefruit, you get more nutrition and no added sweetener. If you chase your morning coffee with a donut, you just gobbled another two teaspoons of sugar from the cruller. Have an eight-ounce container of fruit yogurt with lunch and you are spooning an additional seven teaspoons of sugar on the heap. A cup of ice cream or frozen yogurt for dessert adds another six teaspoons of sugar to your daily intake.
