Article
Full-text available
Almost all foods are processed to some extent, if only by preservation, and it is therefore unhelpful to criticise foods as being ‘processed’. A number of food classifications have been devised that pay special attention to types of processing. A systematic review has shown that, of these, NOVA is the most specific, coherent, clear, comprehensive and...
