This study examined the prevalence, patterns, and health associations of consumer participation in different stages of the food system using a survey of 663 adults in one U.S. county. Consumer food system participation by stage was 43% in food production, 47% in food processing, 65% in food distribution, 62% in food acquisition, 61% in food preparation, and 100% in food consumption. Consumers participated in an average of 3.7 of these 6 possible stages. Women and unmarried people participated in more stages. Food system participation was associated with few health problems, although people reporting some illnesses had higher food system participation.
