Daily Yogurt Decreased Risk for Type 2 Diabetes

Cohorts included nearly 200,000 American medical professionals….

Mu Chen, a doctoral candidate at the Harvard School of Public Health, said in a press release, “Our study benefited from having such a large sample size, high rates of follow-up and repeated assessment of dietary and lifestyle factors.” Chen and colleagues evaluated results from three prospective cohorts that followed medical history and lifestyle habits of health professionals.

The cohorts included 41,497 U.S. male dentists, pharmacists, veterinarians, osteopathic physicians and podiatrists ages 40 to 75 years in the Health Professionals Follow-Up Study (1986-2010); 67,138 U.S. female nurses ages 30 to 55 years in the Nurses’ Health Study (1980-2010); and 85,884 U.S. female nurses ages 25 to 42 years in the Nurses’ Health Study II (1991-2009). Overall, 15,156 type 2 diabetes cases were identified through follow-up. There was no associated risk for type 2 diabetes and total dairy consumption in age- and multivariate-adjusted models among all participants (P>.05).

There was a 4% lower risk with one serving per day increment of dairy consumption in the age-, BMI- and energy-adjusted model. However, further adjustment made the association null. High consumption of yogurt was associated with a lower risk for type 2 diabetes when researchers adjusted for risk for chronic disease. When researchers incorporated other study results with their own, they found that one 28g serving of yogurt per day decreased the risk for type 2 diabetes by 18%.

Practice Pearls:

  • They evaluated results from three prospective cohorts that followed medical history and lifestyle habits of 41,497 male health professionals, 67,138 female nurses aged 30 to 55 years and 85,884 female nurses aged 25 to 42 years.
  • There was a 4% lower risk with one serving per day increment of dairy consumption.
  • They found that one 28g serving of yogurt per day decreased the risk for type 2 diabetes by 18%.
