Days of Cheap Food to End

Mark Hill, food and agriculture partner at Deloitte, the accountancy firm , warned that rising demand for wheat and maize was bound to result in increases in the price of staple foods. The era of cheap, subsidised food, which had lasted since the war, was over, he said. We are going to see sustained price inflation - a general upward trend for staple foods such as grains, milk and meat.

The price of milk, poultry and pork is also expected to increase because of a rise in the cost of livestock feed . Wheat and maize prices are at their highest level in more than a decade.

The growing trend of turning wheat and corn into alternative fuels had come at a time when stocks had been run down. Grain supplies were already under pressure as a result of bad weather that reduced harvests and pushed up prices last year. Population increases and growing affluence in China and India could double global grain consumption within the next 40 years.
