Among South Asian Indians with Type II diabetes, 86% of males and 98% of females have dyslipidemia characterized by low HDL and high LDL levels. Almost 80% of the entire South Asian Indian population have dyslipidemia partially due to the common Indian diet, which is high in carbohydrates and low in healthy fats. However, supplementing diet with 30 grams of unsalted cashews has been shown to increase HDL concentrations in Asian Indian populations with Type II diabetes. A study performed by Departments of Diabetology and Foods, Nutrition & Dietetics Research, Madras Diabetes Research Foundation focused on Asian Indians with Type II diabetes. The experimental group supplemented their regular diet with 30 grams of cashews per day for 12 weeks, while the control group continued with their regular diet. After the 12 weeks, the experimental group showed a 16-fold increase in HDL levels compared to the control group.
