The cost of food and fuel soared in May and that pushed the cost of living up 0.6% - about what analysts had expected:

The Labor Department reported Friday that consumer prices rose by 0.6 percent last month, the biggest one-month increase since last November, as gasoline costs surged by 5.7 percent. Food prices, which have also been rising sharply, were up 0.3 percent as the cost of beef and bakery products showed big gains.

Core inflation, however, which excludes energy and food, edged up a more moderate 0.2 percent in May. That increase was right in line with expectations and should help relieve worries that the big increases in food and energy could be breaking through to more widespread inflation.

Ian Shepherdson, chief U.S. economist at High Frequency Economics, said that the moderate gain in core prices showed price pressures are remaining contained despite fears at the Federal Reserve.

The Fed, which from September through April was aggressively cutting interest rates to fight a mounting economic slowdown, is now indicating that its biggest concern has changed from the threat of a recession to worries about inflation.

In a speech Monday, Fed Chairman Ben Bernanke said that the Fed will "strongly resist an erosion of longer-term inflation expectations." Those comments have raised expectations that the Fed's next move later this year will be to start raising interest rates.
