RESUMO
OBJECTIVES: The aim of this study was to investigate the association between dairy product consumption and plasma inflammatory biomarkers levels among a representative sample of Brazilian adults from São Paulo City. METHODS: Data were acquired from the Health Survey for São Paulo, a cross-sectional population-based study. All individuals 20 to 59 y of age with complete food consumption information (24-h dietary recall and food frequency questionnaire) and blood sample analysis were included (N = 259). The sample was separated into two groups according to systemic inflammatory pattern considering plasma levels of C-reactive protein; tumor necrosis factor-α; soluble intracellular adhesion molecule; soluble vascular cell adhesion molecule, monocyte chemoattractant protein; interleukin-1ß, -6, -8, -10, and -12; adiponectin; leptin; and homocysteine. Multiple logistic regression tests were conducted to estimate the odds ratio for the inflammatory cluster across tertiles of dairy consumption. RESULTS: When adjusted by age, smoking status, and energy intake the odds ratio for the inflammatory cluster group in the highest tertile of yogurt consumption was 0.34 (95% confidence interval [CI], 0.14-0.81) relative to the reference tertile, demonstrating also a linear effect (Ptrend = 0.015). Cheese consumption exhibited an odds ratio of 2.49 (95% CI, 1.09-5.75) relative to the reference. CONCLUSIONS: Increasing yogurt consumption might have a protective effect on inflammation, whereas cheese consumption appears to be associated with a proinflammatory status. The results of the present study aggregate a new perspective on existing evidence demonstrating the importance of assessing the contribution of dairy products on diet and their effect on the development of non-communicable diseases and associated risk factors.

Introdução - Evidências recentes de estudos clínicos e epidemiológicos sugerem uma relação inversa entre o consumo de alimentos lácteos e inflamação, demonstrando a relevância do tema para Saúde Pública diante de sua possível atuação na redução do risco cardiovascular. Objetivo - Avaliar a associação entre consumo de alimentos lácteos e marcadores inflamatórios em uma amostra representativa de adultos residentes no município de São Paulo. Métodos - Trata-se de um estudo com delineamento transversal, de base populacional, que utilizará dados bioquímicos (coleta de sangue) e de consumo alimentar (Recordatório Alimentar de 24 horas e Questionário de Frequência Alimentar) provenientes de 269 indiviÍduos de ambos os sexos e idade entre 19 e 59 anos participantes do ISA Capital - 2008/2009. Resultados - Após ajustes de idade e sexo, o consumo total de lácteos demonstrou correlação inversa com as concentrações séricas de homocisteína e interleucina-8. O tercil de maior consumo de iogurte esteve significativamente associado com menores níveis de interleucina-8, fator de necrose tumoral-, homocisteína, triglicérides e VLDL-colesterol e maiores da leptina quando comparado ao tercil de menor consumo (p<0,005). Os queijos com menor teor de gordura apresentaram seu consumo inversamente associado às concentrações de interleucina-8, proteína quimiotática de monócitos-1 e triglicérides e positivamente com HDL-colesterol e leptina, apesar de também correlacionados ao fator de necrose tumoral- e adiponectina (p<0,005). Os grupos do leite e queijos em geral também estiveram associados com alguns marcadores inflamatórios.
Introduction - Recent evidence from clinical and epidemiological studies suggest an inverse relationship between dairy consumption and inflammation, which demonstrates the relevance of the subject to Public Health considering its possible role on reducing cardiovascular risk. Objective - To investigate the association between dairy products consumption and circulating levels of inflammatory biomarkers among a representative sample of Brazilian adults from São Paulo City. Methods - The data come from a cross-sectional population-based study, Health Survey for São Paulo (HS-SP). All individuals aged 20 to 59 included in this research gave out completed food consumption information (24-hour dietary recall and Food Frequency Questionnaire) and blood sampling analysis totalizing a 269 subjects sample. Results - After age and gender adjustments, total dairy consumption exhibited an inverse relation with both homocysteine and interleunkin-8. A higher consumption of yogurt was significantly associated with lower levels of interleukin-8, tumor necrosis factor-, homocysteine, triglycerides and VLDL-cholesterol and higher of leptin (p for trend 0.005).
