The sharp rise in food prices is being felt acutely by poor families on food stamps, the federal food assistance program.

In the past year, the cost of food for what the government considers a minimum nutritional diet has risen 7.2 percent nationwide. It is on track to become the largest increase since 1989, according to April data, the most recent numbers, from the United States Department of Agriculture. The prices of certain staples have risen even more. The cost of eggs, for example, has increased nearly 20 percent, and the price of milk and other dairy products has risen 10 percent.
