Beef Consumption and Fatty Acids Serum Concentration:Relationship with Salivary Gland Tumors in Córdoba, Argentina

Abstract

Aim: The objective of the present study was toanalyze beef consumption, conjugated linoleic acid (CLA)and n-3 fatty acid (FA) serum concentration and theirrelation to salivary gland tumors (SGT). A questionnaire onnon-nutritional risk factors and a validated food frequencyquestionnaire were applied in 20 SGT and 20 control (Co)patients. Materials and Methods: Food data were processedby the Interfood v.1.3 software. Serum CLA was analyzed bychromatography. Results: Non-significant differences werefound between SGT and Co regarding lean and fatty BC andserum CLA. Serum n-3 linolenic acid concentration washigher in Co than in SGT (p=0.004). No associationsbetween BC and CLA serum concentration were found, but astrong-positive association between total energy intake andtotal fat intake and SGT were observed. A significant inverseassociation between oleic and linoleic FA intake and SGTwas recorded. Conclusion: Serum oleic and linolenic FAsshowed a significant negative association with SGT.
