Answer 2

Because of sodium level in your cell and intercellular media.

Step-by-step explanation:

Your organism works as a perfect mechanism. The part of this mechanism is sodium/potassium pump. If you eat a lot of salty food you will raise the amount of sodium in all of your organism and disrupt the balance with potassium. So you will become thirsty due to your organism needing more water to get rid of excess sodium.
