When the levels of blood sugar are higher than what is normal but not in the range of diabetes, then a person receives a diagnosis of pre-diabetes.
The Center for Disease Control in the U.S. estimates that if a person diagnosed with pre-diabetes ignores symptoms they have between a 15% and a 30% chance of developing the disorder over a period of five years.
In the recent study, researchers made two groups between 54 adults who were pre-diabetic. The two groups followed a diet that was calorie regulated consisting of 50% of energy through carbohydrates, 35% through fat and 15% through protein.
One of the two groups added 57 grams per day of pistachios to their diet, while the other group added olive oil as well as other fats.
By the end of the study of 4 months, insulin, fasting blood sugar levels and the hormonal markers of resistance to insulin dropped in those who added pistachio to their diets. In addition, the same had increased in the other group.
One researcher said that although this work examined pistachios, it is our opinion that any effects that are beneficial on the metabolism of glucose are shared by all types of nuts, as their general composition has lots of compounds that are bioactive to beneficially affect the pathways leading to resistance to insulin and diabetes.
Another researcher added that there had been results that were similar found for walnuts and almonds and said that although it was rare, allergies to nuts might be the only discouraging factor preventing people from including nuts in their daily diet.
Nuts are known to be a healthy rich form of protein and are positive in the diet for other reasons besides diabetes.
