With more tea and wheat in England than ever before, prices dropped. Tea had been a valuable delicacy in the previous century. In the 1800s the average factory worker gulped a cup down with his slice of bread - although in fact this was little better nutritionally than the gruel and ale of previous diets. As commodity production expanded, so did the importance of the British Empire which provided, as well as raw materials, new overseas markets in which mass-produced goods could be sold. Consequently vast amounts of cargo moved across the world, enabling the houses of wealthy Europeans to become crammed with products. At the same time, the colonies became increasingly dependent on European imports.http://www.bl.uk/learning/langlit/booksforcooks/1800s/1800sfood.html

This shows the presence of inflation in the 1800s european society. Over production caused prices to drop on certain produce. As well diets changed due to the cheap prices of certain produce which was now easier to afford.
