In some EU countries, simplified information systems for consumers are developed to inform them about nutritious values. These are e.g. traffic lights and food-choice logo. Juices produced according to the EU directive fulfill criteria for healthy products. 100% pureed juices, especially vegetable juices, are a category of products, which may fulfill conditions set for health and nutritional claims considering the content of several mineral constituents (especially potassium) and vitamins (C, B₆, foliates, β-carotene i vitamin K), and even dietary fibre. Vegetable juices are a better source of nutrients than fruit juices, having also much lower content of carbohydrates, including sugars, and lower caloric value. In some countries, significant position occupy "smoothies", however, this category of products has not been regulated by official rules, contrary to fruit juices. In Poland homogenized juices and nectars based on puree are considered as "smoothies". It is necessary for the industry to adapt to changing market requirements related to legislation changes and to the requirements of rational nutrition. The industry must also take into account wrong habits of the consumers established over many decades. Use of nutritional and health claims may play important role in changing consumers habits but their reliability should be rigorously controlled.
