ISTOCK
Have you ever wondered why some foods, like yoghurt, idli, or even pickles, taste a little tangy? That special flavour comes from fermentation, a natural process where tiny, friendly microbes turn simple ingredients into something tastier and healthier. Fermented foods are not just delicious – they are like superheroes for your gut!
Inside your stomach and intestines lives a whole world of good bacteria. These bacteria help you digest food, absorb nutrients, and even fight off harmful germs. When you eat fermented foods, you add more of these helpful bacteria to your gut. It is like inviting extra helpers to keep your digestive system running smoothly. Yoghurt, for example, contains live cultures that make it easier to digest lactose, which is the sugar in milk. That is why some people who cannot drink plain milk find yoghurt easier on their tummy.
Fermented foods can also boost your immunity. A healthy gut is linked to a stronger immune system, meaning your body is better prepared to fight off infections. Traditional foods like dosa batter, kimchi, miso soup, sauerkraut, and kefir are all examples of fermented goodies packed with beneficial microbes.
The best part? Fermentation also makes food more nutritious. It can increase vitamins, make minerals easier for your body to use, and sometimes even add new flavours that you cannot get from fresh ingredients alone. Think of the soft, spongy idli or the crunchy bite of pickled mango – both are results of fermentation at work.
Idli batter ferments faster in hot weather because microbes love heat.
Blue cheese gets its sharp taste from special moulds that grow during fermentation.
In Korea, families buried kimchi pots underground to keep them cool while they fermented.
