But instant foods never leaves the synthetic preservatives behind. They're going together most of the times, and leave their effects to our body. The effects are mostly negative, such as cancer. Scientist actually suggests that if a substance can kills bacteria, it's also can kills you.

There are actually some substances that can preserve foods without damaging our body. Natural food preservatives are natural substances that can create a hostile environment for microorganism. Therefore, the foods will be fresh for longer times. The following is a list of natural food preservatives:

  1. Salt: Salt dehydrates microbes through the process of known as osmosis. Thus, the microbes cannot lives. Salted meats sometimes can last for many years. The use of salt may not suitable for people who don't like salty foods or not allowed to eat salt for certain reason.
  2. Sugar: Sugar can preserve foods using the osmosis strategy as salt do. It mostly used to preserve fruits.
  3. Vinegar: Vinegar is acidic, and can inhibit the growth of bacteria. There are many kinds of homemade vinegar in your local grocery stores.
