And juices always contain more calories per ounce than fruit. The first clue to how nutritious a juice may be is always the name. But makers now sidestep that reality by not calling their products anything. For example, Mountain Sun has a drink called Cranberry Zip. One look at the nutrition label and it's clear this drink makes no contribution to the diet beyond the calories.
Sugar is sugar whether it occurs naturally in the juice or is added.
Since 1994, the government has required makers to list the percentage of juice in the product on the label, but that's only part of the story. The devil is in the details. All juices are not created equal. If the first ingredient is apple, grape or pear juice, there is no nutritional bang for the buck. No sugar added.
