Abstract: Importance: Clear guidelines on the health effects of dairy food are important given the high prevalence of obesity, cardiovascular disease and diabetes, and increasing global consumption of dairy food. Objective: To evaluate the effects of increased dairy food on cardio metabolic risk factors. Data Sources: Searches were performed until April 2013 using MEDLINE, Science Direct, Google,Embase, the Cochrane Central Register of Controlled Trials, reference lists of articles, and proceedings of major meetings. Study Selection: Randomized controlled studies with healthy adults randomized to increased dairy food for more than one month without additional interventions. Data Extraction and Synthesis: A standard list was used to extract descriptive, methodological and key variables from all eligible studies. If data was not included in the published report corresponding authors were contacted. Results: 20 studies with 1677 participants with a median duration of dietary change of 26 (IQR 10-39) weeks and mean increase in dairy food intake of 3.6 (SD 0.92) serves/day were included. Limitations: Most clinical trials were small and of modest quality. . Conclusion: Increasing whole fat and low fat dairy food consumption increases weight but has minor effects on other cardio-metabolic risk factors.
