A research team from the U.S. and Singapore found that women who eat large amounts of walnuts may be cutting their risk of developing type 2 diabetes. Using participants from the Nurses’ Health Study (NHS) and  Nurses’ Health Study II (NHS II), they followed 58,063 women aged 52–77 years old from the first study and 79,893 women aged 35–52 years old from the second for 10 years. None of the participants had diabetes, cardiovascular disease, or cancer when the studies began.

Every four years, the researchers evaluated how many walnuts the participants consumed through a validated food frequency questionnaire. The participants also reported if they developed type 2 diabetes through a validated supplemental questionnaire. A total of 5,930 type 2 diabetes cases were documented during the 10 years of follow-up.

In the first statistical model, the data was analyzed without including the participants’ body mass index (BMI). the results from this analysis indicated that participants who ate:

  • One-three 28 gram servings per month had a 93 percent chance of developing type 2 diabetes
  • One 28 gram serving per week had an 81 percent chance
  • Two or more serving per week had a 67 percent chance

In the second statistical model, which included BMI, the researchers found that participants who ate:

  • One-three 28 gram servings per month had a 96 percent chance of developing type 2 diabetes
  • One 28 gram serving per week had an 87 percent chance
  • Two or more serving per week had a 76 percent chance

In both analyses, the results suggested that high levels of walnut consumption helps protect women from developing type 2 diabetes.
