The railways changed what we eat and the culinary tastes of the population. Moving produce around at speed was suddenly possible - fresh meat, wet fish, dairy, fruit and veg, were now widely available. And it was in London where arguably the nation's diet changed the most. With a new system of rapid transport it was now possible for the capital to enjoy food supplies from all corners of the nation. Diets improved in terms of the variety and quality of food available. Victorian men and women developed a taste for one particular dish that would be popular with the masses for generations to come - fish and chips.
