AbstractMilk and milk products contribute approximately 22 % of the nation's saturated fat (SFA) intake. Recently, the role of dairy and its SFA composition and link to cardiovascular disease (CVD) has been analysed( 1 ), suggesting a beneficial action of this food group on reducing cardiovascular risk in high-risk groups( 2 , 3 ). The aim of this study was to examine the effects of 4 weeks full-fat cheese on circulating lipoprotein fractions, blood pressure and arterial stiffness in healthy adults. Participants were recruited in the city of Chester, UK. Those meeting entry criteria of: 18–65 years of age, not taking antihypercholesterolaemic or antihypertensive medication took part in the study. Participants were randomised to receive either 50 g of a full-fat Red Leicester (FFC) or placebo (virtually zero fat Cheddar cheese, ZFC) per day for 4 weeks. Anthropometry, blood pressure, brachial and aortic augmentation index (BAIX and AAIX, respectively), pulse-wave velocity (PWV) and a full lipid profile were determined at baseline and post-intervention. Participants were asked to keep a 3-day food diary prior to and for the last 3 days of the protocol. All procedures were approved by the Faculty of Medicine, Dentistry and Life Sciences Research Ethics Committee at the University of Chester. Eighty-six (86) individuals completed the study (43 per group). No significant changes were observed in any measured parameter (Table 1). Both ZFC and FFC groups showed a significant increase in calcium intake during the course of the study (1002·1 ± 639·1 mg to 1815·0 ± 1340·1 mg and 1219·6 ± 1169·1 mg 1845·8 ± 1463·2 mg, P < 0·001, respectively) showing good adherence to the protocol. In conclusion, these results suggest that inclusion of 50 g full fat cheese into the diet of a healthy population does not impact negatively on traditional CVD risk markers. Future strategies to reduce SFA intake should focus on – and acknowledge the importance of the source – of SFA in the diet.
