Bannanas are considered high in K+.

The physiological concentrations sodium,
potassium, and chloride, in the body fliuds of all mammals
is almost exacttly the same as sea water.
Ion | Seawater | Mammals
Na+ | 480mM/L | 142mM/L
K+ | 10 mM/L | 4 mM/L
Ca++ | 11 mM/L | 2.4mM/L
Cl- | 560mM/L | 103mM/L

It is usually excreted with urine in fairly high concentrations,
to maintain the concentration gradients. Low extracellular and
