Will Bananas Ruin My Diet?

As one of the more energy-dense fruits available, bananas might seem like a poor addition to a weight-loss plan -- yet these fruits may actually be a dieter's dream. Packed with fiber, nutrients and tropical flavor, bananas can serve as a healthy snack or accessory to a meal, providing essential nutrition and curbing your appetite without breaking your calorie budget.

Calories and Nutrition

Bananas can provide a boost of nutrients in a relatively low-calorie package. According to the USDA National Nutrient Database for Standard Reference, one medium-sized banana contains only 105 calories, and offers 3 g of fiber, 1 g of protein, 422 mg of potassium, 32 mg of magnesium, 10 mg of vitamin C, 24 mcg of folate and small amounts of vitamin B-6, niacin, riboflavin, thiamin, selenium, manganese and iron. Bananas contain virtually no fat, cholesterol or sodium.

Benefits

Bananas can sweeten your diet without filling your menu with processed sugars or empty calories, making this fruit a healthy way to satisfy your sweet tooth. Due to their abundance of potassium and low content of fat, sodium and cholesterol, bananas may help reduce your risk of high blood pressure and stroke, according to Chiquita Bananas. In addition, fiber-rich foods like bananas may help protect against heart disease, and this fruit's high concentration of vitamin C and vitamin B6 may contribute to a stronger immune system, faster healing times, better iron absorption, improved protein metabolism and greater central nervous system function.

Myths

The concept that bananas are fattening is a pervasive but unfounded nutrition myth. As the Eastern Illinois University dining service explains, bananas are relatively low in calories compared to other foods: It would take six bananas to yield the same number of calories in a single slice of New York-style pizza, for example. Rather than packing on pounds, bananas are more likely to lower your blood pressure and boost your immune system from their matrix of nutrients.

Considerations

Although bananas are packed with nutrition and offer a number of health perks, they're not calorie free. If you're trying to lose weight, don't simply pile bananas on top of your existing eating plan: Use them to replace higher-calorie foods such as cookies, cakes, candy or other desserts, and as with any food, consume them in moderation. If you have a latex allergy, consult your physician and watch for any adverse symptoms after consuming bananas. As Dr. Sumana Reddy explains, latex-sensitive individuals sometimes have reactions to bananas due to their related protein component, and may experience symptoms such as oral itching or even anaphylactic shock.
