Cashew Nuts

Cashewnuts are one of the popular weight-gain dry fruits. A 100gms serving of cashews offers a whopping 553 calories, most of which comes from fat and carbohydrates. Cashews are also body-building foods due to the high amounts of protein present in them. Additionally, they contain copper, iron, phosphorous, potassium etc., making them good weight gain supplements. Just roast some of these nuts and season them with salt and pepper to snack on them.
