The Mediterranean diet, plant-based diets, and diets containing high amounts of fruits and vegetables, nuts, legumes, fish, whole grains, antioxidants, and omega-3 fatty acids and lower amounts of red and processed meat, trans fat, dairy, sugar, sodium, and alcohol are associated with a lower risk of ED.[1][2][3][4][5][6][7]
However, some studies suggest that any association between the type of diet one follows (i.e., Mediterranean, low-fat, low-carbohydrate, ketogenic, vegetarian/vegan, pescatarian) and ED disappears when controlling for age, BMI, and other risk factors.[8][9] Weight loss achieved through a low-fat, low-calorie diet;[10][11], a high-protein, low-carbohydrate diet;[12] a high-protein, low-fat diet; or a high-carbohydrate, low-fat diet[13] improves erectile function in men with diabetes and/or overweight/obesity.
