What is fermentation?
Fermentation, a natural process driven by microorganisms like bacteria and yeast, involves the conversion of carbohydrates such as sugars and starches into alcohol and organic acids. During fermentation unique compounds produced, such as antimicrobial peptides and lactic acid, hinder the growth of pathogenic microorganisms and prevent food from spoiling.
Preserving Food Through Fermentation
Fermentation serves as a natural method for preserving food. For thousands of years, humans have utilized this method to preserve food, enhance flavors, and pioneer new culinary creations. But today food industries, use chemical preservatives for preserving food and overshadowing traditional preservation methods such as fermentation. Chemical preservatives cause serious health hazards.
Fermentation is a natural process that has been used for centuries to preserve food and enhance its flavor and texture.
What are the benefits of fermentation?
Improves Gut health
Eating fermented foods boosts the number of beneficial bacteria, in your gut thereby promoting gut health.
What is Gut health?
The gut microbiome refers to the complex community of microorganisms, including bacteria, viruses, fungi, and other microbes, that reside within the gastrointestinal tract, particularly the colon. These microorganisms play a crucial role in various aspects of human health, including digestion, nutrient absorption, immune function, and even mental health. If your gut microbiome is disrupted, it can cause dysbiosis—which leads to chronic illness.
Fermented foods like can bolster the gut microbiome, creating a healthier mix of microbes and strengthening the walls of the intestines to keep them from leaking.
Improves the availability of nutrients
During fermentation, bacteria synthesize vitamins and minerals, and produce biologically active peptides which eliminate non-nutritive compounds.
Some natural compounds, like phytic acid found in legumes including soy beans, inhibits the absorption of nutrients like iron and zinc. Through fermentation, these “anti-nutrients” are eliminated, thereby rendering them to be easily absorbed.
Helps in synthesizing vitamins & minerals
Enhancing the population of beneficial bacteria in the gut helps promote the manufacture B vitamins and vitamin K.
Adds flavor and texture to food
Fermentation contributes a tangy flavor to foods and adds zest to the meals. Furthermore, fermentation enhances both the taste and texture of foods, enriching the culinary experience.
Helps in digestion
Due to the bacterial breakdown of certain natural sugars and starches, fermented foods become more easily digestible.
Supports immune function
Incorporating a variety of fermented foods into your diet can potentially bolster your immune function and diminish your susceptibility to infections.
Helps Regulate Blood sugar
During fermentation, complex carbohydrates are broken down into simpler sugars, resulting in foods with a relatively low glycemic index.
Helps in improving oral health
Indeed, beneficial bacteria can nourish the microbiome within your mouth, potentially resulting in improved oral health. This may translate to reduced dental plaque and tartar buildup, as well as a decreased risk of cavities and gum disease.
How are foods fermented?
-
-
- Natural fermentation: In this process, also called spontaneous fermentation, the microorganisms that cause fermentation are already in the environment. For example, the fermentation of idli and dosa batter.
- Culture fermentation: This process uses a starter, like a sourdough starter, to ferment foods. Kombucha is another food that uses a starter.
Varieties of fermented food
There are variety of fermented foods like
– Sauerkraut
– Kombucha
– Kefir
– Idli & dosa
– Koozh which is made from ragi or Kambu flour
– Kanji which is a salty and sour Indian probiotic drink made from carrots
Among the many fermented delicacies, one that particularly stands is the idli.
During the fermentation process of idli batter, beneficial bacteria transform the carbohydrates and sugars found in rice and dal into lactic acid. This not only imparts the characteristic tang to idlis but also unleashes a wealth of nutritional benefits.
Idlis are naturally gluten-free, which makes them an ideal option for individuals who are gluten sensitive. Fermented foods like idli are a natural source of probiotics, which promote gut health.
Conclusion
As more people reside in urban areas and adopt Westernized diets, there is often a lack of knowledge about fermentation and limited awareness regarding the nutritional benefits of fermented foods, as well as how to prepare them. Let’s consider a healthier breakfast option.
