If a food has 300 mg of Sodium and 300 mg of Potassium does the potassium NEGATE the sodium's water holding/bloating affects? Me and salt dont get along. Does the potasssium wash out the sodium?
Thanks
In short, no. Sodium or (NaCL) is the main cation (Positively charged ion) in extracelluar fluid (or inside your arteries/veins/capillaries.) Sodium's concentration is over 10x higher in extracellular fluid than intracellular fluid regions, and it is the primary osmotically charged particle responsible for fluid shifting/maintenance within the body.
Potassium (K) in the main cation (Positively charged ion) residing in intracellular fluid (or directly inside the cells themselves.) Potassium's concentration is over 30x great in intracelluar fluid, than extracellular fluid.
The concentration differences between potassium and sodium across cell membranes create an electrochemical gradient known as the membrane potential. A cell's membrane potential is maintained by ion pumps in the cell membrane, especially the sodium, potassium-ATPase pumps. These pumps use ATP (energy) to pump sodium out of the cell in exchange for potassium.
The large proportion of energy dedicated to maintaining sodium/potassium concentration gradients emphasizes the importance of this function in sustaining life.
So, in laymens terms, your body requires a balance of these electrolytes in order to maintain homeostasis (or a normal functioning of body cellular processes.) Sodium is primarily responsible for the shifting of fluids (mainly water) in and out of the cells all while regulating hemodynamic factors such as your blood pressure and normal cellular functioning. Potassium WILL NOT negate the effects of excessive sodium intake.
If you take in an abundance of sodium, you will retain not only extra fluid through enteral (by mouth), but it can even lead to intracellular dehydration despite a euvolemic state (or normal water/fluid extracellular levels.)
