Bananas are Great for You
One large banana is about 8- to 9-inches long and equal to one serving of fruit. It has about 120 calories and 490 milligrams of potassium. That’s 19% of a woman’s daily potassium needs and 15% of a man’s. This nutrient can remove sodium from your body and relax blood vessel walls, which helps manage blood pressure. The golden fruit is also a good source of vitamin B6, which is essential for your immune system, nervous system, and brain.
