Abstract

A randomized-control test of a multimedia nutrition intervention-the Nutrition for a Lifetime System (NLS©)- utilized supermarket receipts to examine effects of NLS treatment on the daily per person nutritional content of participants' supermarket purchases. In regression analyses controlling for background variables, baseline purchases and trends toward increased purchasing, NLS treatment contributed to lower levels of total fat and to higher levels of total fiber and servings of fruits and vegetables at post-test. Redemption of NLS coupons contributed to greater decreases in fat and increases in servings of fruits and vegetables in users' purchases. Implications for future interventions promoting healthier food choices include tailoring program content and addressing broader lifestyle issues such as caloric intake and expenditure.
