Eating just two servings of nuts a day may combat type 2 diabetes

Eating nuts may help to combat type 2 diabetes, new research suggest. 
Two servings of tree nuts a day appears to lower and stabilise blood sugar levels in people with the disease, according to evidence collected from 12 clinical trials. Tree nuts cover most types including walnuts, cashews, hazelnuts and pecans, but exclude peanuts.  A single serving was defined as 30 grams. 
Nut consumption improved two key markers of blood sugar, the results from analysing data on 450 trial participants showed. One, the HbA1c test, measures blood sugar levels over three months. The other, the fasting glucose test, assesses blood sugar after the patient has not eaten for eight hours.
