A Wall Street Journal article warns that a second wave of food inflation may be building. U.S. grocery prices rose 0.4% in October 2026, ending months of quiet food inflation, with fresh food rising faster — lettuce jumped 8% — and food costs climbing at the fastest rate in six months, which the article attributes to snarled supply chains, weather, and fuel prices elevated by the Iran war, with retail diesel up more than 66% to a record $6.53. Economists caution one month proves little, but Scotiabank's Olivier Gervais says the worst of food inflation is yet to come, and Kraft Heinz's Steve Cahillane warns price increases across its portfolio are coming in 2027.
