4 Reasons to Eat More Kimchi

April 03, 2026

Love it or hate it, kimchi is hard to forget once it hits your plate. But there’s a lot more to kimchi than just bold flavors.

This fermented staple has been around for generations, and it comes with real health benefits to back up the hype.

We asked Ulysses Wu, MD, with Hartford HealthCare, for four reasons to make room for kimchi in your weekly routine.

1. It supports gut health

Let’s start with the big one. Kimchi is a fermented food, which means it contains important bacteria that keeps your gut microbiome in balance.

“The probiotics in fermented foods support healthy digestion and overall gut function,” says Dr. Wu. “A healthier gut can affect everything from nutrient absorption to immune health.”

If you’re new to fermented foods, start with small portions and work your way up to avoid any discomfort.

2. It’s packed with nutrients

Kimchi is made primarily with cabbage, so it’s packed with vitamins and nutrients.

“Because kimchi is made from vegetables like cabbage, radishes and scallions, it provides vitamins A, C and K, along with antioxidants,” Dr. Wu says.

And since fermentation helps break down nutrients, your body will absorb them more easily than they would from raw vegetables alone.

3. It supports immune health

Gut health tends to get all the attention, but kimchi may be great for your immune system, too.

“A large portion of the immune system is connected to the gastrointestinal tract,” says Dr. Wu. “Supporting a healthy gut microbiome can help your immune system function more effectively.”

That doesn’t mean kimchi replaces vaccines or good hygiene, but it can be a helpful addition.

4. It adds big flavor with very few calories

Unlike butter and sugar, kimchi can change the flavor profile of your meal without adding fat and calories.

“Kimchi is low in calories but high in flavor, which makes it a great way to add interest to meals without relying on heavy sauces. And depending on the brand and how it’s made, it probably isn’t as spicy as you’d think,” Dr. Wu adds.

Use it as a side dish, mix it into rice or grain bowls or add it to eggs, soups or tacos for an instant upgrade.

How to make kimchi part of your routine

You don’t need to eat a whole jar to see benefits.

“A few spoonfuls a day can go a long way,” says Dr. Wu. “The key is consistency, not quantity.”

Kimchi is easy to find in most grocery stores and some big box stores. Look in the refrigerated section to make sure it still contains live cultures, and don’t be afraid to experiment. Your taste buds — and your gut — will be glad you did.
