Brain-derived neurotrophic factor (BDNF) rs6265 Val/Met and Met/Met variants were negatively associated with the risk for type 2 diabetes. Sex and stress levels had an interaction with BDNF Val/Met in the risk for type 2 diabetes. BDNF rs6265 had consistent gene–diet interactions with energy and protein intake. With low-energy, low-protein, and high-carbohydrate intake, BDNF Val/Met lowered the risk for type 2 diabetes. People with BDNF Val/Val are prone to developing type 2 diabetes even in low energy and protein intake in middle-aged adults.
