Serum Salicylic Acid And Fruit And Vegetable Consumption In Obese And Normal-Weight Children: A Pilot-Study

Salicylic acid (SA), a phenolic compound produced by plants, may play a beneficial role on health. This pilot study evaluated whether there might be an association between serum SA and fruit and vegetable (FV) consumption in obese and normal-weight children. Thirty-four obese children (17 boys and 17 girls) and 34 normal-weight children were recruited. Dietary intake was evaluated by the 7-day dietary record. Serum SA was measured using gas chromatography-mass spectrometry method. FV intake in obese and normal-weight children was not different between groups (175.00 (97.66) g versus 192.29 (90.54) g, p = .455). Obese children had lower serum SA than normal-weight children [ mean difference, -0.025; 95% CI ( -0.044; -0.006) mu mol/L]. Serum SA was not associated with daily intake of FV in obese (p=.111) and normal-weight (p = .092) children. Further studies are needed to evaluate the role of FV on serum SA, taking into account also the quantity and the type.
