A new study has revealed that eating a handful of walnuts everyday can lead to better diet and improvements in health risk factors among people at high risk of diabetes. The study revealed that the walnut diet was associated with improvements in blood vessel cell wall function and ‘bad’ cholesterol after six months, although it didn’t have any impact on blood pressure or blood glucose levels. In the study, researchers assigned 112 people to either following a diet with dietary counselling designed to curb calorie intake, or one without. Within these two groupings, participants were randomly assigned to the daily inclusion of 56 g of walnuts in their diet or the complete avoidance of walnuts for a period of six months.
