What is it? -

Fermented foods are basically just old food. They are 'spoiled' to some degree, but there's a key difference between fermented food and rotten food.

Fermented vs rotten -

When food goes rotten, it is essentially killed and broken down by bacteria. In comparison, fermented food gains beneficial bacteria and does not become dangerous.

Raw food actually increases its nutritional value when fermented. It gains vitamins, minerals, friendly bacteria, and live enzymes.

Bacteria - The human body is home to more than one trillion bacteria. They contribute to around 4 lbs (1.8 kg) of our total body weight!

Bacteria - There are 'good' bacteria and 'bad' bacteria, which need to remain balanced. If there is too much bad bacteria in your gut, you can experience bloating, constipation, or diarrhoea.
