Fermentation has been a part of Indian cooking and eating habits since the very beginning. Our ancestors used to have naturally fermented foods in their daily diets even before commercialized probiotic drinks were a thing. From fermented dough for bread to calming curds and buttermilk, several tasty options can make your tummy happy just like that.

Historically, fermentation was used to preserve food in the absence of refrigerators. Healthy active bacteria like yeast and fungi were added to the foods to increase their shelf lives. Sugar and salts were also very common preservatives at that time. Together they create lactic acid which acts as a natural preservative in foods.

Apart from increasing the life of the foods, probiotics also impact our digestive system. Our gut system is full of millions and trillions of bacteria that are constantly working in different parts of our digestive system. Today, we will try to find the answer about why fermented foods are called healthy and how eating different fermented foods can be good for your digestive system.

What Are Probiotics?

When we talk about probiotics and foods that can be probiotic, fermented foods come to mind first. The process of fermentation makes them rich in good bacteria which is why they are suggested by doctors to help your digestive system. 

Probiotics are live bacteria and yeast that are good for us. Some people think of them as bad organisms but actually, they are very much responsible for the smooth working of our system. There is a larger number of bacteria in our body system which are good for digestion of which they are one.

How Do Fermented Foods Work?

Fermented foods like curd, yoghurt, kombucha and kefir are all probiotic-rich foods. Let's see how they work for our digestion, and why fermented foods are good for your gut.

  1. After a long term illness, when you take a lot of antibiotics, the good bacteria in your stomach can be lost as the PH level of our stomach gets disturbed. That is when probiotics plays their role, and help in restoring the good bacteria. It normalizes the increased PH level with good bacteria and helps your stomach recover.
  2. Probiotics play a great role in keeping a balance between the ‘good’ and the ‘bad’ bacteria in our digestive system. There are about 100 trillion or so bacteria and microorganisms that live in your digestive tract. Research shows that these little fellows (probiotics) help in strengthening your gut microbiomes. That’s why fermented foods, that are rich in probiotics, are the best friends for your gut.

2. Helps to Digest Tough Foods

Tough foods, like sprouts, hard lentils, heavy grains and spicy foods can easily be neutralized with fermented foods (There is a good reason for having Boondi raita with Rajma Chawal). Our traditional Achaar or vegetable/fruit pickles are also good examples of Indian fermented foods.

3. Boosts Immune System
