ADA 2018: Dr. Adham Abdel Mottalib on Dairy Consumption and Type 2 Diabetes

Op-Med is a collection of original articles contributed by Doximity members.

Dr. Adham Abdel Mottalib presented “The Effect of Dairy Consumption and Its Fat Content on Glycemic Control and Cardiovascular Risk Factors in Patients with T2D” at the 78th Scientific Sessions for the American Diabetes Association (June 22–26) in Orlando, FL.

Doximity discussed the research with Dr. Mottalib at ADA 2018. Below is a transcript of the video interview.


Mottalib: Our first study is a randomized controlled study looking into the effects of dairy product consumption on patients with diabetes—things like milk, yogurt, cheese—and is the first study of its kind among this patient population.

What we did is that we randomized patients into three groups: [for] one group, we asked them to increase their daily intake of full fat dairy products; another group were [asked] to increase their daily intake from low or nonfat dairy; and then there was a control group [that] we followed over six months. These people at baseline had uncontrolled diabetes—average A1C was above 8, which is well above what the American Diabetes Association recommends.

What we found is that increasing daily intake had no effect whatsoever on glycemic control as well as body weight.

Doximity: Were there any results that surprised you?

Mottalib: Parent nutrition guidelines for Americans recommend that adults can consume three about three servings of low or nonfat dairy every day. Our research shows that the daily the fat content of the dairy doesn't really matter, so we might be less strict about the low-fat or nonfat part of the dietary recommendations.

Doximity: Can you tell us about you presentation on bariatric surgery?

Mottalib: Another important study that was [represented] at ADA this year [looked] into the effects of bariatric surgery on patients with type 1 diabetes and obesity.

What we found is that patients with type 1 diabetes who had bariatric surgery were able to lose about 25 percent of their body weight and were able to maintain this weight loss over three years. They were able to improve their lipid profile, so they their HDL, which is the good cholesterol, went up; bad cholesterol, or LDL, went down as well as triglycerides.

But the thing that is surprising is that the surgery had no effect whatsoever on their A1C or their glycemic control over the three years.
