1 Your skin can improve.
One medium banana contains 13% of the daily manganese needs—a fairly high percentage for such a small, easy snack. Manganese intake can mean improved skin appearance, because "manganese is essential for making collagen, which creates a youthful appearance and protects against free radical damage that can lead to wrinkles."

2 Your colon will thank you.
Bananas have something called "resistant starch. While starch may sound like a negative—generally, something we try to avoid over-consuming, this resistant starch actually "helps generate the production of short-chain fatty acids.
Short-chain fatty acids "play a vital role in colon health, so the more you generate, the healthier your colon will be.

3 You can avoid muscle cramps.
Bananas contain essential electrolytes that can help keep the body hydrated and balanced. When the body gets out of balance related to our minerals, we can begin experiencing negative side effects like muscle cramps.

4 They can balance out the salt you're eating.
The potassium levels bananas are known for are crucial for overall dietary health, especially if you're loading up on salt in other areas.
Bananas are a rich source of potassium, which is an essential nutrient that helps combat the negative effects of sodium. Having a good level of potassium in your diet is great for your heart health and blood pressure, helping to reduce the risk of strokes and heart disease.

5 They can help you lose weight.
Bananas have a notorious reputation for being high in sugar and high in calories compared to other fruits.
But, despite this seemingly negative reputation, the fruit can actually help with weight control, "due to the fiber and antioxidant content."
Bananas are high in fiber which slows down digestion to make you feel full longer (hello appetite control!) and will normalize your bowel movements. This makes a banana the perfect thing to grab when you are in between meals!
