      Salt and sugar act differently in our bodies, but when it comes to causing thirst, their effects are pretty much the same. Here’s why. Particles of salt or sugar enter the bloodstream soon after we eat them. As they move through the body, they pull water out of our body cells. The cells notice the change right away, and they do not like it! So they try to hold in water and send chemical messages to the brain.
     The brain also has its own sense organs that detect when the blood contains too much sugar or salt. After the brain gets the message that the body needs water to reduce the amount of the sugar or salt, you start to feel thirsty. That is why cookies, candy, or even very sugary soda or juice, can make you just as thirsty as salty foods.
