    Abstract:

    Objective To provide scientific guidance for consumers to choose nutritious and cheap foods, the association between street food prices and nutritional value in Wuhan was analyzed.Methods One gourmet street was randomly selected from Jianghan, Jiang’an and Wuchang District of Wuhan City, respectively. Fifty two kinds of street foods of 6 types (barbecue, frying, steaming, baking, beverage and cold food) were selected, and the prices were recorded. After analyzing the nutrient components through standard testing in laboratory and using nutrition calculators, energy prices and the average price of nutrient-rich food (NRF6.3) index was calculated. The correlation between unit price and NRF6.3 index was analyzed by Spearman rank sum test.Results Baked food had the highest energy density, reaching 308.41 kcal/100 g, while beverages had the lowest energy density, reaching 79.35 kcal/100 g(P<0.001). The energy price was the highest for barbecue (22.47 yuan/100 kcal). And the energy prices of steaming, frying, drinks, baking and cold food were 2.15, 4.88, 3.56, 3.95 and 5.61 yuan/100 kcal. The average price of NRF6.3 index was -2.90/yuan. The food with the highest NRF6.3 index that one yuan could buy was cold food (2.43), and the lowest was steaming food (-11.09). Besides, the price of street food was significant positively correlated with protein (P<0.001), dietary fiber (P=0.014) and fat (P=0.001), and significant negatively correlated with added sugar (P<0.001). There was no rank correlation between the unit price and its NRF6.3 index among 6 types of foods (P>0.05).Conclusion The overall price of street food in Wuhan is relatively high with high energy density, while the price of NRF6.3 index is low. This results suggest that, for the same price, the recommended nutrient content of street food is not high, and the nutritional value is low, which does not meet the requirements of a healthy diet.
