Non-alcoholic beverages are a diverse group of products, including carbonated drinks, still and dilutable drinks, fruit juices, nectars and bottled waters. Some contain sugar, others contain non-caloric sweeteners and yet others are unsweetened. And even the sugar levels of beverages containing sugar vary considerably from one beverage to another. The same goes for energy content, with many non-alcoholic beverages having only a negligible calorie value. In other words, non-alcoholic beverages cannot be classified as one homogenous group.
