160 - Why do we use salt to preserve food?

Salt helps preserve food by stopping the growth of bacteria and other bad organisms that can make us sick. Here's how it works:

  1. Salt sucks out water from the bacteria, making it hard for them to survive.
  2. Salt also makes it difficult for bacteria to move and reproduce.
  3. By controlling bacteria growth, salt helps to keep the food fresh for a longer time.

This way, salt acts like a shield to protect the food from spoiling, allowing us to enjoy our favorite foods for longer.
