Eating too much spicy, salty, and dry food not only leaves you with a dry mouth and throat but can also lead to dry skin and eyes.
When excessive salt enters the bloodstream, it increases the osmotic pressure of the blood. This causes the cells in the interstitial fluid to lose water, leading to dehydration. Spicy foods can accelerate skin blood circulation and increase sweating, which also results in a loss of body moisture. Roasted and fried foods are already low in moisture, and the high-temperature processing makes them very dry. The proteins they contain are hydrophilic substances that are eager to reabsorb the moisture lost during processing. Therefore, as soon as you eat these foods, the moisture in the oral and pharyngeal mucous membranes is ruthlessly drawn away. On top of that, these roasted and fried foods often contain high levels of salt, which is an additional burden for the delicate mucous membranes.
