The claim overstates the actual cumulative increase by roughly a factor of two to three: the real rise since 2015 is around 33–41%, whereas 'almost doubled' implies close to +100%.
Food prices did fall slightly around 2015–2016 (commodity-driven food deflation), so the 2015 base makes the increase look marginally larger than a 2016 base, but still nowhere near a doubling.
The most recent primary source (Eurostat Statistics Explained) reports the change for 2016–2025, a base year one year later than the '2015' stated in the claim; the difference does not affect the conclusion.
