Eating salty and sweet preparations urges you to sip water, this is because of the fact that although salt and sugar act differently in our bodies, but when it comes to causing thirst, their effects are almost the same. Particles of salt or sugar are absorbed into the bloodstream soon after we eat them. The concentration of the blood increases significantly outside the cells as compared to that inside the cells and water is pulles out ouf the cell by a process known as osmosis (movement of molecules from an area of high concentration to an area of lower concentration). The cells notice the change right away, so they try to hold in water, and send chemical messengers to alert the brain. The body pulls intracellular water in order to isotonic concentration of solute in the body.
The brain also has its own sensors that detect when the blood becomes too concentrated with particles of sugar or salt. After the brain gets the message that the body needs water to dilute the sugar or salt, you start to feel thirsty.
Cookies, candy etc. can make you just as thirsty as salty foods like chips, nachos etc. That’s because particles of sugar and salt both pull water out of your body cells and trigger the chain of reactions that make you feel thirsty.Apart from sweet and salty preparations, spicy food preparations also makes us feel thirsty.
Happy Eating :-)
