Research shows that nuts play an important role in preventing type 2 diabetes [1], managing existing diabetes [2], and preventing or reducing the progression of diabetes-related complications [2].
Eating just one handful of nuts four times a week is associated with a 13% reduced risk of developing diabetes [1], and nuts can improve blood glucose levels and lower HbA1c for those with type 2 diabetes [2].

How do nuts help manage diabetes?

• While nuts are not low GI (they don’t have enough carbohydrate), they have a GI lowering effect, meaning that they reduce the overall GI of a meal [3]. 
• Nuts contain mainly healthy unsaturated fats (mono- and polyunsaturated fats), and are low in saturated fats. Replacing saturated and trans fats with unsaturated fats improves insulin sensitivity and reduces T2DM risk [4].
• Nuts are a good source of fibre. Diets high in fibre have been shown to help manage diabetes and metabolic syndrome, and can reduce the risk of developing diabetes [5, 6].
• Most nuts are a rich source of magnesium, which can reduce the risk of developing type 2 diabetes. Magnesium also improves fasting blood glucose and blood lipid levels in people with diabetes [7].

People with diabetes are more than twice as likely to die from cardiovascular disease and are more likely to have abnormal blood lipids including high cholesterol and triglycerides and lower ‘good’ HDL cholesterol [8].
