Behold the mighty salmon. In a 100-gram serving of cooked wild Atlantic salmon, you’ll get an impressive 628 milligrams of potassium (via USDA). Remember, in the same 100-gram serving of raw banana, you’ll find only 358 milligrams of potassium. However, a similar 101-gram serving of raw banana is only the equivalent of a small-sized banana measuring around 6 inches to just under 7 inches long. Most of us aren’t eating a banana that small. Therefore, does salmon still trump a larger-sized banana in terms of potassium content?
Indeed, it does. One medium-sized raw banana measuring between 7 inches and just under 8 inches long contains 422 milligrams of potassium. As you can see, salmon still comes out on top. The same is true even for a large banana measuring between 8 inches and just under 9 inches in length, which contains 487 milligrams of potassium. Even if you ate a banana that is or exceeds 9 inches in length, the fruit would still come up short. The USDA states that this 152-gram extra-large serving of raw banana contains 544 milligrams of potassium. While bananas are undeniably a great source of potassium, we now know that wild salmon definitely is, too.
