This study examines the effect of a meal planner's nutritional awareness, exercise habits, and household socioeconomic characteristics on market participation and frequency of purchase of snack peanuts. Data are from a household survey of 2880 U.S. households collected by Gallup in 1997. Statistical tests showed that a double-hurdle or Cragg model best represented consumers' participation and purchase level decisions in the snack peanut market. The results indicated that meal planner's nutritional considerations while making food purchase decisions had little effect on the participation level decisions, but did affect purchase frequency of snack peanuts. Those household meal planners who were overly concerned about undesirable nutritional factors tended to decrease their purchase of snack peanuts. Promotion of snack peanuts on the basis of nutritional benefits through health professional and media is a useful tool to increase purchase frequency.
