A new trial has found that following a Mediterranean diet (MD) supplemented with extra dairy foods could significantly increase health outcomes for those at risk of cardiovascular disease (CVD).
The study compared an MD with three-four daily servings of dairy (MedDairy), rather than the usual one-two servings, and a low-fat (LF) control diet among 41 participants in Australia aged between 45 and 75, and at risk of CVD. The participants followed the MedDairy and LF intervention for eight weeks, with the two intervention periods separated by an eight-week washout period during which they returned to their usual diet.
The study found that compared with LF, the MedDairy intervention resulted in significantly lower morning home systolic blood pressure (SBP) and diastolic blood pressure as well as clinic SBP. It also resulted in higher high-density lipoprotein (HDL) cholesterol, lower triglycerides, and lower ratio of total to HDL cholesterol, compared to the LF diet.
Presenting the findings in the American Journal of Clinical Nutrition, the authors said the MedDairy diet may be appropriate for an improvement in CV risk factors in a population at risk of CVD.
