Market researcher Kantar said annual grocery inflation was 16.5% in the four weeks to June 11, down from 17.2% in its May data set.
Prime Minister Rishi Sunak's key pledge to halve inflation in 2023 has been undermined by persistently high food inflation.
"Price rises are now being compared to the increasing rate of grocery inflation seen last summer, which means that it should continue to fall in the coming months," he said.
Market leader Tesco (TSCO.L) said on Friday food inflation was starting to ease and it was hopeful it would moderate through the year.
The Kantar data for June provides the most up to date snapshot of UK grocery inflation.
