Street Food (SF) consists of out-of-home food consumption and has old, historical roots with complex social-economic and cultural implications. Despite the emergence of modern fast food, traditional SF persists worldwide, but the relationship of SF consumption with overall health, well-being, and obesity is unknown.
This is an observational, cross-sectional study. The study was performed in Palermo, the largest town of Sicily, Italy. Two groups were identified: consumers of SF (n = 687) and conventional restaurant food (RES) consumers (n = 315). Study subjects answered a questionnaire concerning their health conditions, nutritional preferences, frequency of consumption of SF and a score relative to SF consumption ranging from 0 to 20 was calculated.
Body mass index (BMI, kg/m2) was significantly and independently correlated with the score of street food consumption (r = 0,103; p < 0.002). The prevalence of different diseases, including hypertension and type 2 diabetes, and the use of medications did not differ between the two groups. Milza (a sandwich stuffed with thin slice of bovine spleen and lung) consumers had a significantly higher prevalence of hypertension (12.2% vs 6.2% in non consumers; p < 0.005) and in this subgroup the use of anti-hypertensive drugs was inversely correlated with the frequency of milza consumption (r = 0.11; P = 0.010).
This study suggests that SF consumption in Palermo is associated with a higher BMI and higher prevalence of hypertension in milza consumers. Further studies should evaluate whether frequent SF consumers have unfavourable metabolic and cardiovascular profile.
