In the first study, published online ahead of print in the American Journal of Clinical Nutrition and administered by the Dairy Research Institute™, researchers conducted a clinical trial in which 40 overweight and obese adults with metabolic syndrome were randomly assigned to consume either a low dairy or adequate dairy (at least three servings per day) weight maintenance diet for 12 weeks. They found adequate dairy intake significantly improved multiple health indicators compared to low intake. Markers of both oxidative and inflammatory stress in subjects with metabolic syndrome were reduced. High blood pressure and insulin resistance also showed improvement, while fat mass and waist circumference decreased with no significant change in body weight for either group.
For the second study, published in the European Journal of Clinical Nutrition, Chinese researchers conducted a systematic review and meta-analysis of seven prospective studies examining the association between dairy product consumption and type 2 diabetes. They found higher dairy intake was associated with a 14% reduction in type 2 diabetes risk compared with those with the lowest intakes. Low-fat dairy consumption was associated with an 18% reduction in type 2 diabetes risk; yogurt consumption was associated with a 17% reduction in type 2 diabetes risk. They also found type 2 diabetes risk was decreased 10% with an additional daily serving of low-fat dairy.
“Although additional research is needed, evidence is growing that indicates dairy’s positive role not only in improving health and nutrition but also in reducing risk of chronic disease," said Gregory Miller, Ph.D., president of the Dairy Research Institute and executive vice president of the National Dairy Council.
