Can walnut kernels lower blood glucose?

Walnut kernels generally do not have a blood sugar-lowering effect. The detailed analysis is as follows:

Walnut kernels are one of the more common types of nuts in daily life, containing nutrients such as dietary fiber, vitamins, and amino acids. Eating an appropriate amount can help supplement the body's nutritional needs, increase gastric satiety, and reduce intake of other foods. However, walnut kernels do not possess blood sugar-lowering properties. There is also no clear evidence among known blood sugar-reducing foods that walnuts effectively improve glucose uptake and utilization in the body. Therefore, walnut kernels generally do not lower blood glucose levels.

Walnut kernels have a relatively low carbohydrate content. For individuals experiencing elevated blood sugar, consuming a moderate amount may help reduce overall food intake and thus contribute to better blood glucose control. If blood sugar is only slightly elevated—due to factors such as emotional stress, excessive consumption of high-sugar foods, or mild diabetes—special medical treatment may not be necessary. In such cases, adjusting diet and increasing physical activity may be sufficient for improvement. However, for patients with significantly elevated blood sugar levels that cannot be effectively managed through non-drug methods, medication such as acarbose tablets or pioglitazone hydrochloride tablets should be used under medical supervision.
