Abstract

The aim of this work was to compare the efficacy of two strategies designed to improve folate status: increasing the intake of vegetables, and the consumption of a folic acid-fortified food. Residents (126) from three old people's homes in the Madrid region (Spain) were studied. To each centre a dietary intervention was assigned to be followed for 6 months: (1) the consumption of margarine fortified with 200 μg folic acid/10 g portion (centre M), (2) increasing the consumption of vegetables to three servings per day (centre V), (3) control (centre C). At the beginning and end of the intervention period the subjects' intakes, serum and erythrocyte concentrations of folate were measured. The use of fortified margarine (centre M) led to a significant increase in folate intake (260·9 μg/d), serum concentration (10·3 (sd 8·3) nmol/l) and erythrocyte concentration (638·4 nmol/l). At centre V the increase in total vegetable intake achieved was very poor; these foods met with very poor acceptance, although the intake of certain vegetables particularly rich in folate improved. Therefore, the intake of this vitamin increased a little (26·7 (sd 33·0) μg/d); erythrocyte folate concentration also increased somewhat (460·5 nmol/l), althought less than centre M. The daily consumption of margarine fortified with folic acid was the more effective strategy for improving the folate status of the study subjects.
