Production for self-consumption can meet the principles of food safety such as respect for food habits and diversity. The participation of production for self-consumption in food availability was compared to the purchase of food for 30 days in 79 households (272 inhabitants) of the rural area of a Brazilian city in 2012. The food security was evaluated by the method "Food energy deficiency in the domicile" that classified 12.7% of the households as insecure. In all households, staple foods (rice, pasta, corn, beans, milk, eggs, meats) were available and more than 60% had processed foods (cookies, soft drinks). Only 22.7% of the calories came from production for own consumption and the biggest expense was the purchase of carbohydrates (91.1%), mainly sugar (12.2%). Evaluating only the energy availability of food is not sufficient since the quality and origin of food is of great relevance in the food security condition.
