Scientific explanation

Research-backed

Pistachios provides approximately 560 kcal per 100g, delivering a robust macronutrient profile that includes 20.16g of plant-based protein, 27.17g of carbohydrates, and 45.32g of dietary fat. Of the total carbohydrate content, a significant portion is comprised of dietary fiber (10.6g per 100g), which yields a net carbohydrate count of approximately 16.57g. This high fiber-to-carbohydrate ratio, combined with the presence of healthy monounsaturated and polyunsaturated fatty acids, contributes to an exceptionally low estimated glycemic index (GI) of 15. Consequently, consuming these nuts results in a slow, sustained release of glucose into the bloodstream rather than a rapid spike, making them an excellent option for metabolic health and glycemic control.
