A ton of research suggests limiting sugar-sweetened beverages, which are pretty much the ultimate example of zero nutrition. In fact U.S. Dietary Guidelines suggest there’s strong evidence these beverages contribute to excess weight in adults and children. Surprisingly, some choices in this category are better than others. Ginger ale has 32 grams of sugar per can versus 49 grams in the same amount of cream soda, according to the USDA Food Database. But it might be better to just cut this category of drinks from your diet.
