Pistachio consumption reduces blood sugar, systolic BP and increases HDL levels: Study

Iran: Pistachio consumption could improve some components of metabolic syndrome (MetS), including triglyceride, systolic blood pressure, HDL, and fasting blood glucose, a recent study in Nutrition Reviews has stated. However, the supplementation does not affect anthropometric indices and diastolic blood pressure.

Nut consumption has been shown to reduce the risk of diabetes and coronary heart disease and promote healthy body weights due to their favorable macronutrient profile. Pistachios, compared to other nuts have a balanced nutrition profile with lower fat [polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs)], higher protein, fiber (both soluble and insoluble), potassium, phytosterols, γ-tocopherol, vitamin K, and xanthophyll carotenoids. They are also known for their high antioxidant potential

Previous observational and experimental studies have evaluated the effects of pistachio intake on MetS but have yielded inconsistent results. Soudeh Khanamani Falahati-Pour, Rafsanjan University of Medical Sciences, Rafsanjan, Iran, and colleagues aimed to determine the effect of pistachio consumption on MetS components by performing a systematic review and meta-analysis of data from randomized controlled trials.
