A 4-month in-home study was conducted with 58 volunteer families using a double-blind design to assess home use of regular test salt (RS) and a mineral test salt (MS). No other salt was consumed during the study. All families had a 13-year-old child in a comprehensive school who participated in a community program to influence cardiovascular risks in youths. After 2 months, parents were given a 5-hour (1 hour/week) nutrition counseling course (by a physician and nutritionist) aimed at reducing salt intake. Test salt consumption was measured after 2 and 4 months. At study initiation, and after 2 and 4 months, 24-hour urine samples were taken from the parents and 13-year-olds. Daily home use of test salt decreased insignificantly (2.9 to 2.6 g/family member in the RS group), but significantly (3.4 to 2.9 g/family member) in the MS group. No significant changes in urinary sodium or potassium excretions were noted during the study. This study confirmed the general feeling that reducing salt intake is not easy. More effort is needed from food manufacturers to lower the salt content of foods without impairing their acceptance. (wz)
