Background The study of dietary patterns is gaining interest. Although the health benefits of yogurt and lignans have been investigated separately, to our knowledge there are no studies on their associative effects.Objective The aim of this study was to evaluate a possible association between yogurt and lignans using biomarkers of cardiovascular disease risk in an elderly population.Design We conducted a cross-sectional analysis of the association between baseline dietary information and cardiovascular risk parameters using food frequency questionnaires.Participants We enrolled 7,169 Spanish participants of the PREDIMED (Prevencion con Dieta Mediterranea) study (elderly men and women at high cardiovascular risk) from June 2003 to June 2009.Main outcome measures Cardiovascular risk parameters, including cholesterol, tri-glycerides, glucose, body mass index, weight, waist circumference, and blood pressure were measured.Statistical analysis General linear models were used to assess the relationship between categorical variables (yogurt, total dairy intake, lignans, and yogurt plus lignans) and cardiovascular risk parameters.Results The consumption of either yogurt or lignans seems to have beneficial effects on human health, but the consumption of both showed greater improvement in some cardiovascular health parameters. Indeed, participants with a higher consumption of both yogurt and lignans showed lower total cholesterol (estimated beta-coefficients= -6.18; P=0.001) and low-density lipoprotein cholesterol levels (beta=-4.92; P=0.005). In contrast, participants with lower yogurt and lignan consumption had a higher body mass index (beta=0.28; P=0.007) and weight (beta=1.20; P=0.008).Conclusions High lignan and yogurt consumption is associated with a better cardiovascular risk parameters profile in an elderly Mediterranean population. Further research is warranted to determine the mechanisms and consequences of this potential effect.
