One factor in a healthy diet is the amount of sugar consumed. Sugar comes in many forms, including white sugar, brown sugar, raw sugar, corn syrup, honey and molasses. It provides you with calories, but little else nutritionally, according to the U.S. Department of Agriculture. To avoid getting too many calories from sugar, try to limit the amount of sugars added to your diet to 6 teaspoons a day if you eat about 1,600 calories, 12 teaspoons at 2,200 calories or 18 teaspoons at 2,800 calories. Added sugar doesn't just mean the sugar you add at the table, but also the sugar found in candy, soft drinks, jams, jellies and other sweetened foods.
