The following table provides the answer to this question.
Percentage 1997 58 1998 56 1999 57 2000 56 2001 56 2002 54 2003 53 2004 53 2005 50 2006 49 2007 50 2008 153 1 Provisional. Note: This should not be confused with the measure of UK Self-Sufficiency in all Food, which in 2008 was 60 per cent. (provisional figure), since self sufficiency shows the percentage of all UK food production, including UK exports, as a percentage of consumption. Both measures are based on the value of unprocessed food.
