Beyond Achaar: Why Your Gut Needs Kimchi for A Boost Of Probiotics in Body

Whether it is K-dramas or Korean skin care products, different Korean trends have seen a surge in demand across the global market, including India. One such viral trend is Korean food, and Kimchi, which is a traditional Korean dish, is making headlines for its health benefits alongside its spicy and savoury flavours. In South Asian families, Pickle (Achaar) is a staple used for its tangy and spicy kick, but due to its high oil and vinegar content, many do not feel comfortable consuming it in large quantities. While many consider Kimchi and Pickles to be from the same family, they are nutritionally very different.

You do not need to eat Kimchi just to follow a trend, but for its abundance of health benefits, says our expert, Dr Archana Batra, Dietitian and Certified Diabetes Educator. She further explains how Kimchi helps boost probiotics in your body, making your gut stronger and more balanced. Continue reading to know what else she shared with us.

How Is Kimchi Different From Achaar?

Kimchi is a traditional Korean dish prepared by fermenting vegetables, most commonly Napa cabbage or Korean radish. While it is gaining popularity globally, many in India also compare it to our traditional Pickle.

In conversation with the editorial team of Onlymyhealth, Dr Batra says, "Kimchi is a live fermented food. It is made by fermenting vegetables, usually Napa cabbage or radish, with salt, garlic, ginger, and chilli, allowing beneficial bacteria to grow naturally over time. This process creates a rich source of live enzymes.

Pickle, on the other hand, is typically preserved using oil, salt, vinegar, or heat. Dr Batra explains the difference, "Most commercial and even homemade achaar varieties are not naturally fermented in a way that promotes bacterial growth. Instead, they are meant for preservation and flavour, meaning they do not contain the same level of live probiotics or contribute to microbial diversity in the way Kimchi does." However, earlier, many used to make pickles by fermenting.

Why Your Gut Needs Kimchi

According to a study published in npj Science of Food, fermented foods such as Kimchi help in improving gut bacteria while strengthening the immune system.

"Kimchi actively adds good bacteria to your gut. Most achaar does not offer this benefit unless it is a traditionally fermented, low-oil, sun-matured variety. Kimchi is particularly rich in lactic acid bacteria (LAB), which are essential for a healthy internal ecosystem," notes Dr Batra. These include:

• Lactobacillus plantarum
• Lactobacillus brevis
• Leuconostoc mesenteroides
• How Kimchi Helps In Digestion

The probiotic strains found in Kimchi are known for surviving harsh stomach acid and reaching the intestines alive, which is key to their effectiveness. Dr Batra highlights the specific digestive benefits:

• Improved breakdown of food
• Support for nutrient absorption
• Reduce bloating and gas
• Strengthening the gut lining
• Compete with harmful bacteria

Can Kimchi Improve Immunity and Gut Balance?

Dr Batra emphasises that yes, Kimchi improve immunity and gut balance depending on its cooking process and consumption. "About 70% of our immune cells are located in the gut. Therefore, Kimchi provides a balanced gut microbiome that directly benefits immune signalling," says Dr Batra.

She further explains that the fermentation process facilitates the bioavailability of vitamins such as B vitamins and Vitamin K. "The intense anti-inflammatory compounds found in the garlic, ginger, and chilli used in Kimchi can help increase overall immune function. A better gut equals lower levels of chronic inflammation throughout the body," notes Dr Batra.

How Much Kimchi Is Safe To Eat Daily?

For most people, a little goes a long way. Dr Batra recommends the following:

1. ¼ to ½ cup per day (30–60 g) is usually enough for probiotic benefits.
2. Beginners should start with 1-2 tablespoons and gradually build up to avoid digestive upset.
3. You do not need to eat large quantities, as eating a small amount consistently matters more than volume.

Who Should Not Eat Kimchi?

While it is a nutritional powerhouse, Kimchi isn’t for everyone in unlimited amounts. Dr Batra advises caution if you:

• Have chronic acid reflux, gastritis, or stomach ulcers.
• Suffer from IBS and are sensitive to fermented or highly spicy foods.
• Are on a strictly low-sodium diet.
• Have a known histamine intolerance.

"When it comes to gut health, Kimchi is actually closer to curd or Kanji than it is to modern commercial Achaar. It is a functional fermented food, a powerful tool for your health, not just a condiment, when eaten mindfully and in the right quantity," adds Dr Batra.

Bottomline

The traditional Korean food, Kimchi, does help in overall well-being in many ways, including boosting probiotics in the human body. If consumed systematically and as part of a balanced diet, it can act as a natural shield for your digestive system. While Achaar remains a delicious part of Indian food, incorporating a live-fermented food like Kimchi can provide the microbial diversity your modern gut needs to thrive.
