A. Yes, bananas are considered to be a low-fat fruit. A medium-sized banana typically contains less than 1 gram of fat. The majority of the calories in a banana come from carbohydrates in the form of natural sugars, primarily glucose, fructose, and sucrose. Bananas are also a good source of dietary fiber, vitamins (such as vitamin C and vitamin B6), and minerals (such as potassium). Keep in mind that while bananas themselves are low in fat, the way you prepare or consume them can affect their overall fat content. For example, if you add toppings like peanut butter or chocolate, you'll be adding additional fats to your banana-based snack or meal.
