Alkylresorcinols, phenolic lipids present in high amounts in whole-grain wheat and rye but not present in appreciable amounts in other foods, are candidates as biomarkers of whole-grain intake from these cereals. We estimated the intake of alkylresorcinols in Sweden and the UK using two different methods: food supply data (FSD); food consumption data (FCD; based on individual and household survey data). The average per capita intake of alkylresorcinols in Sweden was 17.5 mg/d (FSD) and 22.9 (SD 16.6) mg/d (FCD), while in the UK it was 11.9 mg/d (FSD) and 11.8 (SD 18.62) mg/d (FCD). Ninety-six per cent of all Swedes consumed some alkylresorcinols, compared with 50 % of British people surveyed. Both women and men over the age of 40 years had a higher alkylresorcinol intake than younger people. The average results from the two methods were similar, but the FCD data provided more detail about the range of alkylresorcinol intake, and indicate that because the intake of alkylresorcinols varies so widely, they may be good markers of diets rich or poor in whole-grain wheat/rye products.
