Fermented foods are packed with beneficial probiotics and have been linked to a broad spectrum of health incentives right from digestion to stronger immune responses.
Take this two-minute read to get an overview of food fermentation, its amazing benefits and safety.
What is Fermentation?
Fermentation is a natural metabolic process where microorganisms like bacteria, yeast, or fungi convert carbs like sugars and starch into alcohol or acids. This process not only helps in preserving food but also improves its flavour, texture, and nutritional profile. Additionally, this process also supports the growth of beneficial gut bacteria, called probiotics. Fermentation has been used for ages in numerous cultures around the world to produce a variety of foods and beverages.

The process of fermentation occurs in two main types:
Alcoholic Fermentation:
This process uses yeast to convert sugars into alcohol and carbon dioxide. It's commonly used in the manufacturing of alcoholic beverages like beer and wine.
Lactic Acid Fermentation:
This method of fermentation uses lactic acid bacteria, which convert sugars into lactic acid. It is commonly used in the making of yogurt, sauerkraut, and pickles.
Potential Benefits of Fermentation
Fermentation offers umpteen benefits, both for the preservation of food and for human health:
Augments Nutritional Value
Fermented foods usually boast impressive nutrients such as vitamins, minerals, and enzymes. For instance, the process of fermentation increases the bioavailability of B vitamins and vitamin K2 in certain foods.
Promotes Digestion
The fermentation process breaks down complex carbohydrates and proteins into simpler and, easier digestible. This is particularly beneficial for people with lactose intolerance, as the fermentation of dairy products reduces their lactose content and supports better assimilation of nutrients.
