What’s the Difference Between Fermenting and Rotting?

Ever wonder what’s the difference is between fermenting and rotting food?

Short Answer:

Rotting is an uncontrolled act of a food decomposing. Dangerous bacteria take over the food in question, breaking it down to a dangerous and foul state. Rotting kills the food.

Fermenting is just the opposite. Fermentation is a controlled process that creates an environment in which the food is placed; when done correctly, beneficial bacteria are produced that discourage the growth of harmful bacteria allowing you to eat it well past its usual shelf life.

Break it down.

During the fermentation process, microorganisms such as bacteria, yeast or fungi convert organic compounds, such as sugars and starch into alcohol or acids.

For example, starches and sugars in vegetables and fruits are converted to lactic acid, and this lactic acid acts as a natural preservative.

The lactic acid is how the food gets its good stuff, the distinctive, intense, slightly sour flavors to common in kimchi, sauerkraut, pickles and the like.

It’s a balancing act.

The challenge is to balance both the good and bad bacteria.

Humans have both good and bad bacteria living in their guts. The good bacteria are called Probiotics. Probiotics are what line your gut and support nutrient absorption and a healthy immune system. They help with digestion, absorption, and absorption of nutrients.

Eating fermented foods on a daily basis will help you build up the colonies of good bacteria and achieve a healthy gut.

It will help your body digest, absorb, and get better use of the foods you’re eating.
