Nutrition and Cost Comparisons of Select Canned, Frozen, and Fresh Fruits and Vegetables

A common call to action for addressing public health concerns of both obesity and hunger is improving access to and consumption of fruits and vegetables. Previous research has examined the nutritional merits of fresh, frozen, and canned fruits and vegetables. However, there are limited data on the cost-effectiveness of fresh compared with processed-that is, canned and frozen-food. This study examined the nutrition delivered in 8 common vegetables and 10 common fruits across multiple packaging options (fresh, frozen, and canned) relative to average costs. A method of scoring based on nutrient intake recommendations was used to calculate the nutrients per calorie, and average costs were obtained from the US Department of Agriculture's Economic Research Service. Nutrient scores for the vegetables were similar across the 3 packaging options, whereas canned vegetables had a lower cost per edible cup compared with frozen and fresh. Nutrient scores were variable for the fruits across the 3 packaging options, and canned fruits were either lower or comparably priced per edible cup. The evidence from this study suggests that fruits and vegetables packaged as frozen or canned are cost-effective and nutritious options for meeting daily vegetable and fruit recommendations in the context of a healthy diet.
