You don't have to have diabetes to benefit from better blood sugar control.The reviewed research showed that sometimes it doesn't have to be very difficult(Parham M, et al. 2014).The participants of this study had type 2 diabetes. One group was given 25g of pistachio nuts as snacks twice a day for 12 weeks while the other group was given a control meal without nuts.After 12 weeks the groups were switched so the group that got the test meal now received the nuts. The pistachio nuts reduced fasting blood glucose, HbA1c (a measurement of long term glucose control), blood pressure, BMI (body mass index) and CRP an inflammatory marker.All this from just eating some nuts.
