Folic acid content of the diet in various types of British household

The total folic acid content of household diets in Britain has been derived from National Food Survey records for 1979, 1980 and 1981, and was found to average 210-213 micrograms/person/day. There were only small regional differences, with the South East of England and East Anglia having higher and Scotland having lower intakes than the average. Income differences were more marked, with households depending on unearned income having the highest intakes. The largest differences were found between households of different compositions groups: households without children obtained between 215 and 257 micrograms/person/day but those containing six or more people averaged only between 168 and 194 micrograms/person/day.
