The USDA reports 358 mg of potassium per 100 grams of raw banana. We have good news for fruit haters. One healthy protein has more potassium per serving.
The powerful salmon. Cooked wild Atlantic salmon has 628 mg of potassium per 100 grams (USDA). Only 358 milligrams of potassium are in a 100-gram raw banana.
A similar 101-gram serving of raw banana is merely a little banana, 6–7 inches long. Most of us don't eat little bananas. Does salmon still have more potassium than a larger banana?
Yes, it does. A medium-sized raw banana (7–8 inches) has 422 milligrams of potassium. Salmon still dominates. Even a huge banana (8–9 inches) has 487 mg of potassium.
Even a 9-inch banana would be short. A 152-gram extra-large raw banana has 544 milligrams of potassium, according to the USDA. Wild salmon is now known to be high in potassium, like bananas.
That's down from 628 milligrams in the same-size wild-caught salmon dish. Farmed salmon narrowly beats the 101-gram small-sized banana, which has 362 milligrams of potassium.
Salmon, farmed or wild-caught, is healthy. Healthline reports that potassium may lower cardiovascular disease risk. In a 2017 JCI Insight rodent study, potassium deficiency was linked to heart disease.
They found that mice with less potassium had more calcium accumulation in their arteries and stiffer aortas. Conversely, increasing potassium intake reduced vascular calcification and aortic stiffness, both cardiovascular disease risk factors.
