Correlation is not causation. As a European myself here is another correlation that probably has a lot more to do with the fact that people in Europe are not buying as much high quality food:

After the politicians printed so much money in order to pay for COVID costs, general inflation has accumulated to 18% or so, split in two years of 8-9%.

Basic food after Ukraine disruption of cereal and oils and increment in energy prices went up over 30%.

The fact that buying buying basic food is 30% more expensive I believe has a lot more to do with people looking for alternatives, specially poor people that could not pay the higher prices anymore.
