Using Mintel's definition, the healthy snacks market generated $14.6 billion in food, drug store and mass merchandiser (FDM) sales in 2004, an increase of 7% from 2002. For most of the foods listed above, Mintel included total FDM sales for each when determining the healthy snack market size, assuming that the foods are consumed primarily as snacks. However, four of these foods—cereal, cheese, yogurt, and snack bars—often are consumed either as a meal replacement or as part of a meal (for instance, a yogurt for lunch or a slice of cheese in a sandwich). Therefore, for these categories, Mintel included a portion of sales representing the “snacking market” for each food, based on the average percent of eating occasions that the food is consumed as a snack, according to a June 2005 consumer survey.
