We have entered a new 'age of eating' where most of our calories come from an entirely novel set of substances called Ultra-Processed Food - industrially processed, and designed and marketed to be addictive. For too long we've been told we just need to make different choices, when really, we're living in a food environment that makes it nigh-on impossible. This is a book about our right to know what we eat and what it does to our bodies, and the right to eat and enjoy good, affordable food.
