Forget Kimchi. Malaysia's Own Fermented Foods Are Gut-Health Superstars Too!

Whether you’re pairing them with ulam or a side of steamed rice, these condiments are a must-try for any spice lover.

Lately, it feels like kimchi is everywhere.

Korean fermented cabbage is reportedly growing on Amazon at roughly 25% year-over-year. Sauerkraut has its own TikTok subculture. Sourdough still commands a cult following five years after the pandemic baking boom.

Meanwhile, here in Malaysia, most of us are walking past the very foods that the wellness world is now scrambling to "discover."

The truth is, our nenek and tok were eating probiotics long before "probiotic" was a word on a Yakult bottle. Long before there were RM200 jars of artisanal kimchi at upmarket grocers. We just called it makan kampung.

Here are four traditional Malaysian fermented foods that, by any honest reading of the science, deserve a seat at the global wellness table — possibly at the head of it.

1. Tempeh - The Protein Powerhouse

Made from soybeans bound together by the soft white mycelium of Rhizopus mould, tempeh is the kind of food that makes nutritionists' eyes light up. It is rich in plant protein, comes packed with prebiotics that feed your gut bacteria, and — uniquely — contains live microbial cultures that researchers have linked to a more diverse, more resilient gut microbiome.

Studies on fermented soy have observed measurable increases in beneficial gut bacteria like Bifidobacterium and Lactobacillus — the same bugs you pay good money for in probiotic supplements at the pharmacy.

Maybe it is time we stop treating it like filler and start treating it like the everyday wellness food it actually is.

2. Tapai — The Sweet, Slightly Boozy Heirloom

Tapai is the dessert with a secret. Made by fermenting glutinous rice (tapai pulut) or cassava (tapai ubi) with ragi — a starter culture of yeasts and lactic acid bacteria — it gives off that distinctive sweet-tart-faintly-alcoholic aroma that anyone with a Malay grandmother recognises instantly.

What is happening inside that little banana-leaf parcel is microbial poetry. Researchers studying Malaysian tapai have identified yeasts like Saccharomyces cerevisiae working alongside lactic acid bacteria including Lactobacillus plantarum and Lactobacillus brevis — the same families of bacteria celebrated in fancy European yoghurts and supermarket kombuchas.

The poetic thing is, tapai shows up most often during Hari Raya, kenduri, and weddings. Malaysians were quietly serving a probiotic-rich functional dessert at every major celebration for generations. We just never had the marketing budget for it.

3. Budu — Kelantan's Liquid Gold

If you have ever sat down to nasi kerabu and watched someone drizzle a dark, deeply pungent sauce over the rice, you have met budu.

Made by fermenting whole anchovies in salt for months — sometimes nearly a year — budu is to Kelantan what fish sauce is to Vietnam, what soy sauce is to Japan, what garum was to ancient Rome. It is umami in its rawest, most uncompromising form.

It is also a microbial ecosystem in a bottle. Studies have isolated Bacillus subtilis and other halophilic (salt-loving) microbes from traditional budu, with some Malaysian research even pointing to potential anti-cancer compounds developed during the long fermentation. The same process that gives budu its powerful flavour also breaks proteins down into bioavailable amino acids — making the nutrients easier for the body to absorb.

A teaspoon goes a long way. Bukan untuk yang lemah hati, but for those who have grown up with it, no nasi kerabu tastes right without it.

4. Cincalok — Melaka's Little Pink Wonders

Drive into Melaka, take the turn-off toward Klebang, and you will start seeing roadside stalls selling small bottles filled with what looks like translucent pink confetti. That is cincalok — tiny shrimp (udang geragau) fermented with salt and a little rice for just three days.

The fermentation here is short and bright. It produces a tangy, salty, faintly fizzy condiment that pairs with fried fish, sliced chilli padi, and shallots like it was born to. Researchers have identified Bacillus amyloliquefaciens among the dominant microbes in cincalok — a strain studied for its antimicrobial properties against unfriendly bacteria like Salmonella and Listeria.

Translation: cincalok is not just delicious. It is also doing some quiet protective work inside your gut.

So Why Are We Still Talking About Kimchi?

Part of it is honest marketing. South Korea has spent decades — and serious public investment — turning kimchi into a global wellness symbol. Part of it is the wellness industry's tendency to find new, "exotic" foods to spotlight every few years.

There is no good reason that tempeh, tapai, budu, and cincalok should not stand alongside kimchi, miso, and sauerkraut on any honest list of the world's great fermented foods.

The science is there. The flavours are there. The cultural depth is unmatched.

The only thing missing is us, treating them with the seriousness they deserve.
