The Mediterranean diet offers a range of health benefits. However, previous studies indicate that the restricted consumption of red meat in the diet may affect long-term sustainability in non-Mediterranean countries. A 24-week randomised controlled parallel cross-over design compared a Mediterranean diet supplemented with 2-3 serves per week of fresh, lean pork (MedPork) with a low-fat control diet (LF). Thirty-three participants at risk of CVD followed each intervention for 8 weeks, with an 8-week washout period separating interventions. The primary outcome was home-measured systolic blood pressure. Secondary outcomes included diastolic blood pressure, fasting lipids, glucose, insulin, C-reactive protein (CRP), body composition and dietary adherence. During the MedPork intervention, participants achieved high adherence to dietary guidelines. Compared with the MedPork intervention, the LF intervention led to greater reductions in weight (Delta = -0 center dot 65; 95 % CI -0 center dot 04, -1 center dot 25 kg, P = 0 center dot 04), BMI (Delta = -0 center dot 25; 95 % CI -0 center dot 03, -0 center dot 47 kg/m(2), P = 0 center dot 01) and waist circumference (Delta = -1 center dot 40; 95 % CI -0 center dot 45, -2 center dot 34 cm, P < 0 center dot 01). No significant differences were observed for blood pressure, lipids, glucose, insulin or CRP. These findings indicate that Australians are capable of adhering to a Mediterranean diet with 2-3 weekly serves of fresh, lean pork. Larger intervention studies are now required to demonstrate clinical efficacy of the diet in populations with elevated blood pressure.
