Normal Heart Function
Having a banana at breakfast every day adds a nutrient to
your body to support normal heart function. Bananas are rich in a mineral
electrolyte called potassium. When potassium enters your body, it absorbs
directly into your bloodstream through intestinal walls. Potassium travels
around to cells all over your body and dissolves in fluid inside of cells. It
travels across cell membranes if needed to keep fluid balanced in and around
cells. This process keeps electricity flowing throughout your system, which is
required to make your heart beat. In cases of severe potassium deficiency, your
heart rhythm may become irregular, which can be deadly. According to the Linus
Pauling Institute, you need 4,700 milligrams of potassium on a daily basis.
Bananas provide more than 360 milligrams per 6-inch piece of fruit.
