ABSTRACT
AIM: The objective of the present study was to analyze beef consumption, conjugated linoleic acid (CLA) and n-3 fatty acid (FA) serum concentration and their relation to salivary gland tumors (SGT). A questionnaire on non-nutritional risk factors and a validated food frequency questionnaire were applied in 20 SGT and 20 control (Co) patients. MATERIALS AND METHODS: Food data were processed by the Interfood v.1.3 software. Serum CLA was analyzed by chromatography. RESULTS: Non-significant differences were found between SGT and Co regarding lean and fatty BC and serum CLA. Serum n-3 linolenic acid concentration was higher in Co than in SGT (p=0.004). No associations between BC and CLA serum concentration were found, but a strong-positive association between total energy intake and total fat intake and SGT were observed. A significant inverse association between oleic and linoleic FA intake and SGT was recorded. CONCLUSION: Serum oleic and linolenic FAs showed a significant negative association with SGT.
